    Description: The objective of this research work was to evaluate the effectiveness of free games in the development of creative thinking in 5-year-old students of the Educational Institution Nº 329 of Huancavelica. The methodology of free games offers a dynamic and active education to students, which encourages the development of creative thinking in 5-year-old students, through a greater sense of security and self-confidence. This methodology was carried out in a motivating environment and free areas, focusing on dynamic and motivating participation, in order to strengthen their abilities and skills, seeking for them to develop autonomous learning. With the results obtained, it can be affirmed that free games directly favor the development of creative thinking in 5-year-old children, since Student's t-test with 53 degrees of freedom, for independent samples, with a significance of 5%, shows a value of 0.038, which is lower than the value proposed, accepting the alternative hypothesis as valid.

    Description: La educación de nuestros días está inmersa en un conflicto de complejas dimensiones y reproduce las desigualdades en la distribución de bienes y saberes a nivel internacional. Es posible afirmar que la educación vive una suerte de modernización sin modernidad, que se manifiesta por contar con infraestructuras de alto nivel formal y tecnológico, bajo condiciones de desigualdad y de opresión individual y social. Dicho escenario, que alcanza su mayor expresión en las naciones más pobres del planeta, se expresa tambien de una manera inocultable en prácticamente todos los países - incluyendo naturalmente los de América Latina y el sur de Europa-.Por sus alcances globales, la modernización es un factor que enlaza -real o virtualmente- a grupos y a individuos más allá de las fronteras geográficas. En tal sentido, el eje configurado por la modernización y la educación pone en contacto a determinados segmentos sociales que, de manera independiente a sus orígenes culturales y regionales, llegan a encontrar grandes afinidades entre sí merced a sus condición e intereses socioecónomicos. En la educación de principios del siglo XXI, los grandes avances y los indicadores exitosos siguen teniendo como contraparte la ignorancia y la desigual distribución social y regional del conocimiento.

    Description: Education is a complex phenomenon made up of multiple factors that interact simultaneously, since it involves the participation of all social actors. From the epistemological point of view, Education allows us to reflect on the educable nature of the human being; it studies the educational phenomenon from a rational and emotional point of view that delves into the person as a being linked to his environment, to society and to the culture to which he belongs.

    Description: It is evident that having solid reading and writing skills is fundamental to achieve an outstanding academic performance during the university stage; both competencies constitute modes of knowledge construction and, therefore, are fundamental in the social, academic and professional development of human beings. In this sense, reading and writing skills allow students to integrate into the disciplinary discursive communities and to achieve participation and success in the tasks of textual analysis and production, necessary for their learning process (Carlino, 2005). Thus, several researches have been concerned with investigating the deficiencies in the reading and writing levels of students entering university (Colectivo Comunicación, 2002; Flórez et al., 2005; Pérez and Rincón, 2013), since this difficulty is related to academic failure and dropout in higher education (Benítez et al., 2021; Guerrero, 2018; Mendoza et al., 2022; Olave-Arias et al., 2013).

    Description: Es evidente que tener habilidades sólidas de lectura y escritura resulta fundamental para lograr un desempeño académico sobresaliente durante la etapa universitaria, ambas competencias se constituyen en modos de construcción del conocimiento y, por tanto, son fundamentales en el desarrollo social, académico y profesional del ser humano. En ese sentido, las competencias de lectura y escritura permiten que los estudiantes se integren en las comunidades discursivas disciplinares y que logren ser partícipes y exitosos en las tareas de análisis y producción textual, necesarias para su proceso de aprendizaje (Carlino, 2005). Es así, que diversas investigaciones se han preocupado por indagar sobre las deficiencias en los niveles de lectura y escritura de los estudiantes de nuevo ingreso a la universidad (Colectivo Comunicación, 2002; Flórez et al., 2005; Pérez y Rincón, 2013), ya que esta dificultad se relaciona con el fracaso académico y el abandono en la educación superior (Benítez et al., 2021; Guerrero, 2018; Mendoza et al., 2022; Olave-Arias et al., 2013).

    Description: Quizás después de la salud y la economía, el tercer gran damnificado con la crisis planetaria es el mundo del trabajo, los mercados laborales advierten cambios sensibles: competencia global, aumento del desempleo en los mercados formales, mayor vulnerabilidad de los mercados informales, profundidad de la precariedad, generalización de la incertidumbre laboral para todos. La mayor consecuencia de esta crisis y gran depresión planetaria de la que quizás nos demoremos toda esta década siguiente en recuperarnos, como fue el caso de la gran depresión de 1929, es que deberemos soportar grandes pérdidas, lo que no deja de enfrentarnos a un proceso de trauma y duelo por ello. Se perderán empleos, 195 millones, en el mundo y 14 millones en América Latina dice la Organización Internacional del Trabajo (OIT); se perderá capacidad adquisitiva derivada de una constricción del salario, en algunos sectores perderán hasta el 50 % de su ingreso mensual (turismo, entretenimiento, transporte, etc.). Se perderá también riqueza sobre todo en los que estaban en condición de independencia laboral, autónomos, y emprendedores, quienes no solo han perdido sus empleos, sino sus empresas, sus emprendimientos; perderán lo que habían ganado y hasta los ahorros de toda su vida, perderán su patrimonio. Los empleados, en su gran mayoría, perderán no solo el empleo y el valor de su salario, también perderán todos aquellos beneficios adicionales: primas legales y extralegales, apoyos económicos para educación y bienestar, bonos complementarios de compensación, etc. Estas pérdidas han quedado profundizadas de manera acelerada, en cuestión de semanas; los efectos y capacidad de recuperación se calculan en no pocos años.

    Description: En América Latina y especialmente en Colombia una de las principales barreras para el ejercicio pleno de los derechos humanos, particularmente el de la educación, ha sido la discriminación o exclusión de las personas o grupos que históricamente han representado las minorías dentro del sistema educativo. Hacer frente a esta problemática y a sus causas, en el suroccidente colombiano, ha sido el foco de atención en el diseño, estructura y puesta en marcha de la prueba piloto de la creación del Observatorio de Educación Inclusiva–OEI de la Facultad de Educación de la Universidad Santiago de Cali. Una de las experiencias más significativas de su funcionamiento, ha sido el trabajo articulado con el Centro de Apoyo para la Inclusión y la REIS (Red de Educación e Inclusión Social), las cuales constituyen dos de las cinco unidades operativas del observatorio, con una I.E del municipio de Candelaria–Valle, Colombia. En ese lugar, se abordó la inclusión desde las reflexiones sobre las ¨Perspectivas de Género y la Diversidad Sexual con enfoque diferencial¨, con el propósito de poder sentar bases para la prevención del bullying, la salud mental en los contextos educativos, así como también, para la prevención de la intimidación y la ideación suicida, y finalmente, para garantizar la sana convivencia, los am bientes escolares libres de discriminación y el rendimiento escolar en niños, niñas y adolescentes.

    Description: Tejiendo Paz desde las Aulas es un texto en el que se reúnen las voces de diferentes investigadoras e investigadores latinoamericanos en torno a un tema que debe ser fundamental en la formación de los maestros. El texto, desde su título, es una apuesta por la revisión juiciosa de uno de los aspectos más importantes en el escenario de la vida cotidiana de la escuela: la convivencia escolar. Como en una representación teatral se reúnen todos los días en la escuela los distintos actores que, en el cumplimiento de sus roles, toman diversas actitudes que determinan las relaciones que entre ellos se establecen. Adultos, niños y adolescentes, reacomodan sus formas de actuar para establecer las normas de convivencia en la escuela. En este punto es pertinente aclarar que, cuando se habla de normas, no necesariamente se hace referencia a las aceptadas por los sistemas educativos; en la mayoría de los casos estas normas que rigen los comportamientos (especialmente entre los estudiantes), son normas recreadas a partir de las vivencias que en algunos casos se constituyen en una normalización de la agresión escolar.

    Description: Al comenzar la labor de prologar este libro me encontré en una posición familiar para mí: sin saber qué hacer. Y, ante la ignorancia y el no conocimiento del siguiente paso, pensé: ¿Qué es lo que hace un investigador? Pues curiosea, investiga, pregunta, hasta que descubre cual es el siguiente paso, que es lo que toca hacer ahora. Y en la búsqueda está el camino. En la investigación el investigador se va formando a sí mismo, impulsado por dos cosas: 1) El reconocimiento de que no sabe y 2) El querer saber. La humildad académica y la curiosidad son el combustible y motor del investigador, sin ellos la investigación no existe. En el momento en el que se tiene una actitud de “saberlo todo” el camino se ha terminado. Rosaura Rojas Monedero es una investigadora, ya que en ella están presentes ambos elementos, junto con un tercero muy particular, que si se combina con la humildad académica y la curiosidad se logran resultados extraordinarios: la pasión. Rosaura es una mujer apasionada por saber, por investigar, y sobre todo por lograr lo que se propone. Tuve la fortuna de conocer este proyecto desde su génesis, cuando una estudiante del Doctorado en Métodos Alternos de Solución de Conflictos de la Facultad de Derecho y Criminología de la Universidad Autónoma de Nuevo León, del cual soy egresada, me contactó buscando una guía adicional para la elaboración de su tesis.

    Description: Posterior a la Restauración de la República – como hoy se conoce al periodo en el que, en el terreno de las armas y hasta cierto punto en el de las ideas, el grupo liberal juarista se impuso sobre los conservadores– se inició en nuestro país un movimiento de renovación educativa que caló hondo y puso sobre la mesa de las discusiones la tarea de formar maestros que dominaran las ciencias de la educación y el “arte de enseñar”.

    Description: El presente capítulo busca exponer algunas de las teorías sobre la “memoria colectiva” que son consideradas como parte del “canon” de las ciencias culturales (Kulturwissenschaften) alemanas. Esta línea de pensamiento se distingue de los estudios culturales o “cultural studies” anglosajones en que su enfoque está dirigido al tema de la memoria colectiva y a su conexión con las ciencias históricas43. No obstante, en el contexto anglosajón han surgido teorías culturales que analizan a profundidad la relación entre imaginarios y el poder político, lo cual complementa necesariamente a las ciencias culturales de esta vertiente alemana. En este texto, el objetivo es presentar dicha producción de conocimiento de las ciencias culturales alemanas, así como algunas miradas críticas desde los contextos anglosajón y francófono para, finalmente, elaborar una reflexión de esta producción de conocimiento desde América Latina. Es decir: ¿qué nos aportan las ciencias culturales en sus vertientes alemana, anglosajona y francófona en el sentido de elaborar cuestionamientos en torno a la memoria colectiva? ¿cuál es el aporte de un diálogo con estas epistemologías? Más allá, es importante XXpreguntarnos por las limitantes de dicho canon desde contextos del sur global si queremos reflexionar sobre estos temas desde México. ¿Qué cuestionamientos y vetas de investigación pueden proponerse y abrirse en torno a la memoria colectiva y la enseñanza de la historia en México desde una reflexión crítica de este corpus teórico?

    Description: La historia de las comunidades indígenas según Luis Villoro ha estado escrita desde una mirada que “juzga”, desde una “realidad disfrazada” y un discurso y lenguaje ideológico que ha excluido la visión del propio indígena. Argumenta: “la historia se oculta detrás de una especie de «metahistoria». Esta trasposición de la historia abstracta es la labor que realiza sin proponérselo conscientemente la ideología” (Villoro, 1998, p. 10). El autor hace crítica además de una mirada del pasado indígena generalizadora o mitológica, recomienda: “El indio se considerará, desde el principio, como un caso más en la humanidad, como un pueblo entre los similares (...)” (Villoro, 1998, p. 178).

    Description: Las medidas implementadas a propósito del COVID-19 han desencadenado una doble crisis. Por un lado, está la sensación de vulnerabilidad que provoca en la mayoría de las personas un virus que ha mostrado la capacidad de arrebatar la vida sin discriminar edad, género, etnia o condición socioeconómica. Por otro lado, ha quedado al descubierto la fragilidad de las seguridades sobre las cuales han reposado las prácticas habituales que organizan nuestra vida social en sus distintos ámbitos: el mundo del trabajo, el financiero, las dinámicas económicas, las relaciones familiares e interpersonales en general. Ambos desdoblamientos han sido intersectados por un discurso intimidante acerca del colapso que podríamos experimentar como sociedad, en caso de no adaptarnos a los efectos inevitables del virus y flexibilizar las medidas restrictivas del aislamiento en función de una pronta activación de las actividades productivas que dan vida a la economía.

    Description: El objetivo central de esta propuesta es poner en consideración algunas reflexiones sobre cómo será la universidad pospandemia, luego de los cambios vertiginosos ocurridos a partir del COVID-19. El recorte ontológico está puesto en la interfase entre salud mental y educación universitaria, a partir de un ejercicio de “futurología” sobre los posibles aspectos y desafíos que enfrentarán las instituciones de educación superior luego de la pandemia. Estas reflexiones están inspiradas en la Teoría de la Subjetividad y la Epistemología Cualitativa creada por González Rey (2012a; 2012b; 2014; 2016; 2017; 2019); González Rey y Mitjáns Martínez, (2017; 2016); González Rey y Patiño Torres, (2017); Patiño y Goulart, (2020), Patiño y Goulart, (2016), perspectiva que estudia la unidad simbólico/emocional subyacente en las tramas de vida de las personas, grupos y colectivos.

    Description: Education, Recent History and Memory. Research and Methodological Approaches: Recent Latin American history has been marked by processes of political radicalization, dictatorships, authoritarianism and armed conflicts. Education, pedagogical thinking and educational policies in the region were not immune to these historical conditions. This work studies the intersections between the recent history of education, on the one hand, and memory, on the other, a field which adopted methodological perspectives with specific features. The compiled chapters attempt to answer some key questions for Argentina and Colombia: how to approach the role of pedagogical ideas in the revolutionary projects, in the configuration of schools, in the circulation and confrontation of memories about a traumatic past? What place do educational policies and the commitment of educators occupy in the approach to social and political conflict?

    Description: Existe una tendencia mundial a pensar que por culpa de la pandemia del COVID-19, la educación debe pasar de lo presencial a lo virtual, de un momento a otro, como si fuera una actividad tan sencilla a la que no se le debe dar tanto tiempo en adoptarse o en asumirse como una nueva o novedosa forma de aprender. En todos los niveles, desde preescolar hasta la universidad, los educandos han tenido que cambiar intempestivamente la forma de acceder al conocimiento, y en este cambio abrupto se han visto inmiscuidos, por su injerencia directa en ese proceso, los padres de familia, las instituciones educativas, los profesores y la sociedad misma; todos han tenido que acoplarse a pesar de su disposición, tiempo, deseos, miedos, dudas, incertidumbres y otras tantas situaciones, a esta nueva forma que si bien se desarrolla en un medio virtual al que casi todos acceden frecuentemente, muy pocos la habían relacionado directamente con la, tal vez, única forma de continuar los estudios actualmente, esto ha traído cierta crisis en este entorno porque ha costado un desgaste emocional tanto de unos como de otros.

    Description: A finales de la década de los años ochenta del siglo pasado, la historiografía de la educación en México tuvo un cambio significativo, pues a partir de ese momento, comenzaron a surgir estudios que planteaban la posibilidad de reconstruir historias del pasado educativo que en la “historiografía tradicional” no habían sido contempladas. En este sentido, nuevos objetos de estudio han ido cobrando relevancia en las investigaciones en torno a la historia de la educación; las mujeres, los niños, el magisterio, los libros escolares o la cultura escolar forman parte hoy en día de esos objetos en los que los investigadores de la educación se han interesado. Esta inquietud por conocer cómo era la educación de ayer, ha trazado horizontes de investigación en donde la interdisciplinariedad ha tenido un lugar preponderante. El diálogo que la Historia ha podido sostener con otras ciencias como la Antropología, la Sociología o la Pedagogía (por mencionar algunos ejemplos) ha enriquecido los trabajos en Historia de la Educación en los últimos años. La diversidad de sujetos históricos que se han ido estudiando ha mostrado las peculiaridades que la educación ha tenido en nuestro país; cada una de las particularidades que los investigadores han encontrado deben considerarse como las piezas de un rompecabezas.

    Description: El presente capítulo aborda la política pública como una respuesta organizada del Estado con relación a necesidades sentidas por la población, basada en un sentido ético de la acción política, entendida como la actividad mancomunada de los que sienten tales necesidades. Entendemos que la política pública es colocada como un horizonte límite en el análisis, lo que no permite profundizar en la calidad de la justicia y los bienes jurídicos a defender. Por tanto, este capítulo reclama un análisis y reflexión, por parte de las profesiones asistenciales, que vaya más allá de los límites de una política o programa concreto accediendo a las necesidades sentidas por los afectados y sus formas de organización socio-política, de tal manera la justicia aparecería como un nuevo horizonte reflexivo que hasta ahora no se presenta con claridad. Para estas reflexiones nos servimos de la investigación Visibilizando la Paternidad Adolescente en Contextos de Pobreza, financiada por la Comisión Sectorial de Investigaciones Científicas de la Universidad de la República, especialmente de las entrevistas realizadas a técnicos que trabajan en torno al embarazo a edades tempranas.

    Description: La crisis planetaria derivada de la de salud pública desatada por la pandemia del COVID-19 ha replanteado las reglas de juego de la geopolítica, la economía y la convivencia social en tiempos de globalización. Esta pandemia tuvo como primer impacto el colapso del sistema sanitario, y como segundo, el ingreso a una cuarentena a nivel global que paralizó la sociedad y la economía, y nos empujó a un confinamiento preventivo. Esto a su vez implicó el empuje hacia la virtualización de las actividades, tales como la educación remota y el teletrabajo, o mejor aún, el trabajo en casa, de manera intempestiva, involuntaria e improvisada; acelerando así el ingreso en la cuarta revolución industrial, pues el trabajo y estudio apoyado en la tecnología virtual basada en internet, que iba a tomar dos décadas en instalarse como modelo dominante, tomó ahora solo tres meses. Esta virtualización improvisada e impuesta es la vez antídoto y veneno, pues permite seguir con las actividades laborales, académicas y sociales, pero a la vez trae riesgos para la salud mental de los seres humanos y la expansión de un estado de malestar general: que se suma al, de por sí, malestar del confinamiento.

    Description: El Colegio de San Ignacio de Loyola fue una institución que tuvo su origen en el año de 1732, cuando un grupo de vascongados residentes en la capital del virreinato de la Nueva España, tomó la decisión de abrir un establecimiento que tuviera como objetivo principal, el asilo y el cuidado de las mujeres novohispanas que se encontraban en una situación de vulnerabilidad social; es decir, viudas o huérfanas. De acuerdo con la concepción cultural de la época, las mujeres debían ser protegidas de los males que la vida podía tener, los mismos que se asociaron con la calle, la ociosidad y la falta de virtudes cristianas y morales. Los vascos y navarros que fundaron el Colegio y que pertenecían a la Cofradía de Nuestra Señora de Aránzazu, estaban convencidos que el sector femenino debía contar con los cuidados necesarios dentro del hogar; de esta manera, se evitaría que las mujeres cayeran en tentaciones malsanas y, que por el contrario, estuvieran entregadas a la vida familiar, al cuidado de los hijos y apegadas a las prácticas cristianas que arraigaban en ellas las virtudes femeninas de amor y compasión hacia el próximo.

    Description: The purpose of this book is to explain the process of establishing the seven Spanish grand colleges where a large part of the State and the Church elite servants were educated in the 16th and 17th centuries. To this end those colleges are considered, first, in the framework of the European collegiate movement, before placing them in the Spanish one. A study of the institutional system of those foundations follows and, in the process, several given truths are challenged. The book closes with an analysis of the careers of the individuals educated in those ‘schools’ for high bureaucrats – labelled as ‘schools of empire’ – which, with the time, became a power within the State thus causing its disappearance.---El propósito de esta obra es explicar el proceso de creación de los siete colegios mayores, en los que se formó gran parte de la elite que gestionó las principales instituciones del Estado y de la Iglesia en la España de los siglos XVI y XVII. Para ello, se sitúan primero los colegios en el contexto general del movimiento colegial europeo, antes de considerar específicamente el movimiento colegial español. Se describe después el sistema institucional de esas fundaciones, consideradas como un todo, y se cuestionan algunos planteamientos generalmente aceptados en torno a las mismas. En la tercera parte se analiza la proyección profesional de los colegiales formados en esas “escuelas” de formación de altos burócratas –a las que se denomina “escuelas de imperio”– los cuales, con el tiempo, acabarán convirtiéndose en una potencia dentro del Estado, provocando así su desaparición.

    Description: El Segundo Congreso Internacional de Humanidades Digitales fue co-organizado por primera vez con una institución universitaria, la Facultad de Humanidades y Artes de la Universidad Nacional de Rosario. Desde el título elegido, La cultura de los datos, la sede(s), la modalidad de organización y la orientación multinivel y transdisciplinaria es reflejo del desarrollo teórico, experimental y transformador que la AAHD desea plasmar año tras año al invocar un espacio colaborativo de saberes, impulsando sus ya habituales modos de hacer y compartir proyectos durante sus jornadas. En estas Actas, la cultura de los datos aparece como el eje de las presentaciones y debates, que revisa nuestras taxonomías y prácticas en tanto creadores o usuarios de datos. Los trabajos también habilitan reflexiones sobre los modos y contextos de circulación, y sobre la difusión y preservación de datos, ya que no son ubicuos ni ahistóricos. Se reflejan aquí trabajos colaborativos, comunidades e infraestructuras, ya que “data are relata”, los datos solo tienen sentido si están relacionados con otros datos, fenómenos, procesos, personas, comunidades. Los datos solo tienen sentido si están organizados y en este libro encontramos las claves actuales para ese proceso.

    Description: Este libro reúne los trabajos presentados en el I Encuentro Cuerpo, educación y sociedad (Ensenada, 7 al 9 de noviembre de 2016). Las temáticas abordadas en los mismos se vinculan de manera más o menos directa con los temas de investigación que se desarrollan en el Centro Interdisciplinario Cuerpo, Educación y Sociedad. Todos ellos vinculados al cuerpo, las prácticas corporales, su educación y formación en las sociedades contemporáneas. Hay trabajos más generales, vinculados a problematizaciones conceptuales y trabajos más específicos vinculados a problemas histórico-empíricos. Los ejes a partir de los cuales se problematiza el cuerpo, las prácticas corporales y su educación pasan por el juego, las sexualidades, las artes performáticas y la discapacidad entre otros. Dentro de estas características se ubican, tanto las presentaciones de las ponencias como las de los paneles e incluimos también una pequeña síntesis de los talleres de trabajo con el interés de mostrar los diversos modos en que la investigación sobre el cuerpo, su educación y las prácticas corporales se llevan a cabo en los momentos de transmisión de contenidos.

    Description: This book studies the configuration of the freedom of higher education in Spain and in Europe during the 19th century. After a comparative study of European reality (France, Germany, Belgium, Italy, Great Britain and the United States), the book shows that in Spain, during the Revolutionary Sexennium (1868-1874), measures were carried out that were in the European vanguard. The study analyzes, at different stages, who had a monopoly on university education; if professors could freely teach a program; if students had freedom to organize their studies and exams; if the University was free to grant its degrees; and if the university degrees allowed the holder to directly and freely practice his profession. The book concludes with an extensive appendix of legislation, speeches and other virtually unknown materials of the Revolutionary Sexennium.---Este libro estudia la configuración de la libertad de enseñanza superior en España y en Europa durante el siglo XIX. Tras un estudio comparado de la realidad europea (Francia, Alemania, Bélgica, Italia, Gran Bretaña y Estados Unidos), en el libro se muestra que en España, durante el Sexenio Revolucionario (1868-1874), se llevaron a cabo medidas que estuvieron en la vanguardia europea. El estudio analiza, en las diferentes etapas, quién tenía el monopolio de la enseñanza universitaria; si los docentes podían enseñar libremente un programa; si los estudiantes gozaban de libertad para organizar sus estudios y sus exámenes; si la Universidad tenía libertad para otorgar sus títulos; y si los grados universitarios facultaban a su titular para ejercer directa y libremente su profesión. El libro concluye con extenso apéndice de legislación, discursos y otros materiales prácticamente desconocidos del Sexenio Revolucionario.

    Description: Se estudia en esta obra colectiva el papel desempeñado por la Junta para Ampliación de Estudios e Investigaciones Científicas (JAE) y la Junta de Educaçao Nacional (JEN) en la renovación de los métodos y las prácticas educativas en los centros de enseñanza secundaria de los dos países ibéricos en el primer tercio del siglo XX. Se aborda ese objetivo mediante una doble estrategia. Por una parte, se ofrece la biografía colectiva e individual de más de una cincuentena de profesores de instituto pensionados por la JAE en el extranjero que contribuyeron a la renovación de la enseñanza secundaria. Por otro lado, se ofrecen diversos estudios de caso que muestran las innovaciones que se introdujeron en la enseñanza de las ciencias y de las humanidades en institutos españoles y liceos portugueses entre 1900 y 1936. Así se analizan los cambios producidos en la interacción con los objetos científicos para evaluar qué tipo de enseñanza experimental se llevó a cabo, y se realizan aproximaciones a los dispositivos visuales usados en las aulas para potenciar la enseñanza por los ojos, como fueron las placas de cristal y el cine.

    Description: Wind tunnel tests have been conducted on an NACA 2412 airfoil section at Reynolds number of 2.2 x 10(exp 6) and Mach number of 0.13. Detailed measurements of flow fields associated with turbulent boundary layers have been obtained at angles of attack of 12.4 degrees, 14.4 degrees, and 16.4 degrees. Pre- and post-separated velocity and pressure survey results over the airfoil and in the associated wake are presented. Extensive force, pressure, tuft survey, hot-film survey, local skin friction, and boundary layer data are also included. Pressure distributions and separation point locations show good agreement with theory for the two layer angles of attack. Boundary layer displacement thickness, momentum thickness, and shape factor agree well with theory up to the point of separation. There is considerable disparity between extent of flow reversal in the wake as measured by pressure and hot-film probes. The difference is attributed to the intermittent nature of the flow reversal.

    Description: The implementation of a two-equation k-omega turbulence model into the NPARC flow solver is described. Motivation for the selection of this model is given, major code modifications are outlined, new imputs to the code are described, and results are presented for several validation cases: an incompressible flow over a smooth flat plate, a subsonic diffuser flow, and a shock-induced separated flow. Comparison of results with the k-epsilon model indicate that the k-omega model predicts simple flows equally well whereas, for adverse pressure gradient flows, the k-omega model outperforms the other turbulence models in NPARC.

    Description: An approach for solving the compressible Euler and Navier-Stokes equations upon meshes composed of nearly arbitrary polyhedra is described. Each polyhedron is constructed from an arbitrary number of triangular and quadrilateral face elements, allowing the unified treatment of tetrahedral, prismatic, pyramidal, and hexahedral cells, as well the general cut cells produced by Cartesian mesh approaches. The basics behind the numerical approach and the resulting data structures are described. The accuracy of the mixed volume grid approach is assessed by performing a grid refinement study upon a series of hexahedral, tetrahedral, prismatic, and Cartesian meshes for an analytic inviscid problem. A series of laminar validation cases are made, comparing the results upon differing grid topologies to each other, to theory, and experimental data. A computation upon a prismatic/tetrahedral mesh is made simulating the laminar flow over a wall/cylinder combination.

    Description: Measurements of wing buffeting, using root strain gages, were made in the NASA Langley 0.3 m cryogenic wind tunnel to refine techniques which will be used in larger cryogenic facilities such as the United States National Transonic Facility (NTF) and the European Transonic Wind Tunnel (ETW). The questions addressed included the relative importance variations in frequency parameter and Reynolds number, the choice of model material (considering both stiffness and damping) and the effects of static aeroelastic distortion. The main series of tests was made on three half models of slender 65 deg delta wings with a sharp leading edge. The three delta wings had the same planform but widely differing bending stiffnesses and frequencies (obtained by varying both the material and the thickness of the wings). It was known that the steady flow on this configuration would be insensitive to variations in Reynolds number. On this wing at vortex breakdown the spectrum of the unsteady excitation is unusual, having a sharp peak at particular frequency parameter. Additional tests were made on one unswept half-wing of aspect ratio 1.5 with an NPL 9510 aerofoil section, known to be sensitive to variations in Reynolds number at transonic speeds. The test Mach numbers were M = 0.21 and 0.35 for the delta wings and to M = 0.30 for the unswept wing. On this wing the unsteady excitation spectrum is fairly flat (as on most wings). Hence correct representation of the frequency parameter is not particularly important.

    Description: Analytical investigation of dynamic stall on HAWT (horizontal-axis wind turbines) rotor loads was conducted. Dynamic stall was modeled using the Gormont approach on the MOD-2 rotor, treating the blade as a rigid body teetering about a fixed axis. Blade flapwise bending moments at station 370 were determined with and without dynamic stall for spatial variations in local wind speed due to wind shear and yaw. The predicted mean flapwise bending moments were found to be in good agreement with test results. Results obtained with and without dynamic stall showed no significant difference for the mean flapwise bending moment. The cyclic bending moments calculated with and without dynamic stall effects were substantially the same. None of the calculated cyclic loads reached the level of the cyclic loads measured on the MOD-2 using the Boeing five-minute-average technique.

    Description: A coordinated effort has been underway over the past four years to elevate unstructured-grid methodology to a mature level. The goal of this endeavor is to provide a validated capability to non-expert users for performing rapid aerodynamic analysis and design of complex configurations. The Euler component of the system is well developed, and is impacting a broad spectrum of engineering needs with capabilities such as rapid grid generation and inviscid flow analysis, inverse design, interactive boundary layers, and propulsion effects. Progress is also being made in the more tenuous Navier-Stokes component of the system. A robust grid generator is under development for constructing quality thin-layer tetrahedral grids, along with a companion Navier-Stokes flow solver. This paper presents an overview of this effort, along with a perspective on the present and future status of the methodology.

    Description: Grid generation plays an integral part in the solution of computational fluid dynamics problems for aerodynamics applications. A major difficulty with standard structured grid generation, which produces quadrilateral (or hexahedral) elements with implicit connectivity, has been the requirement for a great deal of human intervention in developing grids around complex configurations. This has led to investigations into unstructured grids with explicit connectivities, which are primarily composed of triangular (or tetrahedral) elements, although other subdivisions of convex cells may be used. The existence of large gradients in the solution of aerodynamic problems may be exploited to reduce the computational effort by using high aspect ratio elements in high gradient regions. However, the heuristic approaches currently in use do not adequately address this need for high aspect ratio unstructured grids. High aspect ratio triangulations very often produce the large angles that are to be avoided. Point generation techniques based on contour or front generation are judged to be the most promising in terms of being able to handle complicated multiple body objects, with this technique lending itself well to adaptivity. The eventual goal encompasses several phases: first, a partitioning phase, in which the Voronoi diagram of a set of points and line segments (the input set) will be generated to partition the input domain; second, a contour generation phase in which body-conforming contours are used to subdivide the partition further as well as introduce the foundation for aspect ratio control, and; third, a Steiner triangulation phase in which points are added to the partition to enable triangulation while controlling angle bounds and aspect ratio. This provides a combination of the advancing front/contour techniques and refinement. By using a front, aspect ratio can be better controlled. By using refinement, bounds on angles can be maintained, while attempting to minimize the number of Steiner points.

    Description: A direct numerical simulation (DNS) algorithm has been developed and validated for use in the investigation of crossflow instability on supersonic swept wings, an application of potential relevance to the design of the High-Speed Civil Transport (HSCT). The algorithm is applied to the investigation of stationary crossflow instability on an infinitely long 77-degree swept wing in Mach 3.5 flow. The results of the DNS are compared with the predictions of linear parabolized stability equation (PSE) methodology. In-general, the DNS and PSE results agree closely in terms of modal growth rate, structure, and orientation angle. Although further validation is needed for large-amplitude (nonlinear) disturbances, the close agreement between independently derived methods offers preliminary validation of both DNS and PSE approaches.

    Description: Two F-18 aircraft were flown, one above the other, in two formations, in order for the shock systems of the two aircraft to merge and propagate to the ground. The first formation had the canopy of the lower F-18 in the inlet shock of the upper F-18 (called inlet-canopy). The flight conditions were Mach 1.22 and an altitude of 23,500 ft. An array of five sonic boom recorders was used on the ground to record the sonic boom signatures. This paper describes the flight test technique and the ground level sonic boom signatures. The tail-canopy formation resulted in two, separated, N-wave signatures. Such signatures probably resulted from aircraft positioning error. The inlet-canopy formation yielded a single modified signature; two recorders measured an approximate flattop signature. Loudness calculations indicated that the single inlet-canopy signatures were quieter than the two, separated tail-canopy signatures. Significant loudness occurs after a sonic boom signature. Such loudness probably comes from the aircraft engines.

    Description: A multiblock, discrete sensitivity analysis method is used to couple a direct optimization method and a flow analysis method. The domain is divided into smaller subdomains for which the sensitivities are obtained separately. Then, an effective sensitivity equation is solved to complete the coupling of all the sensitivity information. The flow analysis is based on the thin-layer Navier-Stokes equations solved by an implicit, upwind-biased, finite-volume method. The method of feasible directions is used for the present gradient-based optimization approach. First, a transonic airfoil is optimized to investigate the behavior of the method in highly nonlinear flows as well as the effect of different blocking strategies on the procedure. A supercritical airfoil is produced from an initially symmetric airfoil with multiblocking affecting the path but not the final shape. Secondly, a two-element airfoil is shape optimized in subsonic flow to demonstrate the present method's capability of shaping aerodynamically interfering elements simultaneously. For a very low and a very high Reynolds number cases, the shape of the main airfoil and the flap are optimized to yield improved lift-to-drag ratios.

By factoring out the rapidly varying terms in the complex-time development operator in the interaction representation, better approximate expressions can be obtained. As a result, the spectral density can be expressed in terms of the line-coupling functions in which two coupled lines are arranged symmetrically and whose frequency detunings are omega - 1/2(omega(sub ji) + omega (sub j'i'). Using the approximate values omega - omega(sub ji) results in expressions that do not satisfy the detailed balance principle. However, this principle remains satisfied for the symmetrized spectral density in which not only the coupled lines are arranged symmetrically, but also the initial and final states belonging to the same lines are arranged symmetrically as well.

    Description: To identify planform characteristics which have promise for a highly maneuverable vehicle, an investigation was conducted in the Langley Subsonic Basic Research Tunnel to determine the low-speed longitudinal aerodynamics of 21 planform geometries. Concepts studied included twin bodies, double wings, cutout wings, and serrated forebodies. The planform models tested were all 1/4-in.-thick flat plates with beveled edges on the lower surface to ensure uniform flow separation at angle of attack. A 1.0-in.-diameter cylindrical metric body with a hemispherical nose was used to house the six-component strain gauge balance for each configuration. Aerodynamic force and moment data were obtained across an angle-of-attack range of 0 to 70 deg with zero sideslip at a free-stream dynamic pressure of 30 psf. Surface flow visualization studies were also conducted on selected configurations using fluorescent minitufts. Results from the investigation indicate that a cutout wing planform can improve lift characteristics; however, cutout size, shape, and position and wing leading-edge sweep will all influence the effectiveness of the cutout configuration. Tests of serrated forebodies identified this concept as an extremely effective means of improving configuration lift characteristics; increases of up to 25 percent in the value of maximum lift coefficient were obtained.

    Description: The computational fluid dynamics code, PARC3D, is tested to see if its use of non-physical artificial dissipation affects the accuracy of its results. This is accomplished by simulating a shock-laminar boundary layer interaction and several hypersonic flight conditions of the Pegasus(TM) launch vehicle using full artificial dissipation, low artificial dissipation, and the Engquist filter. Before the filter is applied to the PARC3D code, it is validated in one-dimensional and two-dimensional form in a MacCormack scheme against the Riemann and convergent duct problem. For this explicit scheme, the filter shows great improvements in accuracy and computational time as opposed to the nonfiltered solutions. However, for the implicit PARC3D code it is found that the best estimate of the Pegasus experimental heat fluxes and surface pressures is the simulation utilizing low artificial dissipation and no filter. The filter does improve accuracy over the artificially dissipative case but at a computational expense greater than that achieved by the low artificial dissipation case which has no computational time penalty and shows better results. For the shock-boundary layer simulation, the filter does well in terms of accuracy for a strong impingement shock but not as well for weaker shock strengths. Furthermore, for the latter problem the filter reduces the required computational time to convergence by 18.7 percent.

    Description: An optimization procedure is developed for the simultaneous improvement of the aerodynamic and sonic boom characteristics of high speed aircraft. From a sonic boom perspective, it is desirable to minimize the first peak in the overpressure signal at a specified distance away from the aircraft. From aerodynamic point of view, the aerodynamic drag coefficient ratio must be minimized while maintaining the lift coefficient at desired level. The optimization procedure is applied to wing-body configurations related to high speed aircraft. The objectives of this current research are: (1) development of a multiobjective optimization procedure for aerospace vehicles with the integration of sonic boom and aerodynamic performance criteria; and (2) development of semi-analytical approach for calculating sonic boom design sensitivities.

    Description: During the Higher Harmonic Control Aeroacoustic Rotor Test, extensive measurements of the rotor aerodynamics, the far-field acoustics, the wake geometry, and the blade motion for powered, descent, flight conditions were made. These measurements have been used to validate and improve the prediction of blade-vortex interaction (BVI) noise. The improvements made to the BVI modeling after the evaluation of the test data are discussed. The effects of these improvements on the acoustic-pressure predictions are shown. These improvements include restructuring the wake, modifying the core size, incorporating the measured blade motion into the calculations, and attempting to improve the dynamic blade response. A comparison of four different implementations of the Ffowcs Williams and Hawkings equation is presented. A common set of aerodynamic input has been used for this comparison.

    Description: An extensive quantity of airload measurements was obtained for a pressure-instrumented model of the BO-105 main rotor for a large number of higher-harmonic control (HHC) settings at Duits-Nederlandse Wind Tunnel (DNW). The wake geometry, vortex strength, and vortex core size were also measured through a laser light sheet technique and LDV. These results are used to verify the BVI airload prediction methodologies developed by AFDD, DLR, NASA Langley, and ONERA. The comparisons show that an accurate prediction of the blade motion and the wake geometry is the most important aspect of the BVI airload predictions.

    Description: This is a guide for the use of the pressure disk rotor model that has been placed in the incompressible Navier-Stokes code INS3D-UP. The pressure disk rotor model approximates a helicopter rotor or propeller in a time averaged manner and is intended to simulate the effect of a rotor in forward flight on the fuselage or the effect of a propeller on other aerodynamic components. The model uses a modified actuator disk that allows the pressure jump across the disk to vary with radius and azimuth. The cyclic and collective blade pitch angles needed to achieve a specified thrust coefficient and zero moment about the hub are predicted. The method has been validated with experimentally measured mean induced inflow velocities as well as surface pressures on a generic fuselage. Overset grids, sometimes referred to as Chimera grids, are used to simplify the grid generation process. The pressure disk model is applied to a cylindrical grid which is embedded in the grid or grids used for the rest of the configuration. This document will outline the development of the method, and present input and results for a sample case.

    Description: Future hypersonic vehicles are going to be designed largely with computational fluid dynamic methods based on appropriate physical models. The question on how much of this design process can be completed with the present state of computational aerothermodynamics is addressed. Some limitations of current models are discussed. It is shown that much more research is required before it will be possible to accurately design a hypersonic vehicle for all of its flight conditions. The quantities that must be computed accurately so that a minimum weight hypersonic vehicle can be designed are discussed. The use of computational fluid dynamics methods coupled with current thermochemical models in order to compute the quantities under specific flow conditions is considered.

    Description: An experimental investigation was conducted to determine the aerodynamic characteristics of a store as it was separated from the lee side of a flat plate inclined at 15 deg to the free-stream flow at Mach 6. Two store models were tested: a cone cylinder and a roof delta. Force and moment data were obtained for both stores as they were moved in 0.5-in. increments away from the flat plate lee-side separated flow region into the free-stream flow while the store angle of attack was held constant at either 0 deg or 15 deg. The results indicate that both stores had adverse separation characteristics (i.e., negative normal force and pitching moment) at an angle of attack of 0 deg, and the cone cylinder had favorable separation characteristics (i.e., positive normal force and pitching moment) at an angle of attack of 15 deg. At an angle of attack of 15 deg, the separation characteristics of the roof delta are indeterminate at small separation distances and favorable at greater separation distances. These characteristics are the result of the local flow inclination relative to the stores as they traversed through the flat plate lee-side flow field. In addition to plotted data, force and moment data are tabulated and schlieren photographs of the stores and flat plate are presented.

    Description: A high Reynolds number investigation of a commercial transport model was conducted in the National Transonic Facility (NTF) at Langley Research Center. This investigation was part of a cooperative effort to test a 0.03-scale model of a Boeing 767 airplane in the NTF over a Mach number range of 0.70 to 0.86 and a Reynolds number range of 2.38 to 40.0 x 10(exp 6) based on the mean aerodynamic chord. One of several specific objectives of the current investigation was to evaluate the level of data repeatability attainable in the NTF. Data repeatability studies were performed at a Mach number of 0.80 with Reynolds numbers of 2.38, 4.45, and 40.0 x 10(exp 6) and also at a Mach number of 0.70 with a Reynolds number of 40.0 x 10(exp 6). Many test procedures and data corrections are addressed in this report, but the data presented do not include corrections for wall interference, model support interference, or model aeroelastic effects. Application of corrections for these three effects would not affect the results of this study because the corrections are systematic in nature and are more appropriately classified as sources of bias error. The repeatability of the longitudinal stability-axis force and moment data has been accessed. Coefficients of lift, drag, and pitching moment are shown to repeat well within the pretest goals of plus or minus 0.005, plus or minus 0.0001, and plus or minus 0.001, respectively, at a 95-percent confidence level over both short- and near-term periods.

    Description: An experimental investigation was conducted to determine the effect of diverter wedge half-angle and nacelle lip height on the drag characteristics of an assembly consisting of a nacelle fore cowl from a typical high-speed civil transport (HSCT) and a diverter mounted on a flat plate. Data were obtained for diverter wedge half-angles of 4.0 deg, 6.0 deg, and 8.0 deg and ratios of the nacelle lip height above a flat plate to the boundary-layer thickness (h(sub n)/delta) of approximately 0.87 to 2.45. Limited drag data were also obtained on a complete nacelle/diverter configuration that included fore and aft cowls. Although the nacelle/diverter drag data were not corrected for base pressures or internal flow drag, the data are useful for comparing the relative drag of the configuration tested. The tests were conducted in the Langley Unitary Plan Wind Tunnel at Mach numbers of 1.50, 1.80, 2.10, and 2.40 and Reynolds numbers ranging from 2.00 x 10(exp 6) to 5.00 x 10(exp 6) per foot. The results of this investigation showed that the nacelle/diverter drag essentially increased linearly with increasing h(sub n)/delta except near 1.0 where the data showed a nonlinear behavior. This nonlinear behavior was probably caused by the interaction of the shock waves from the nacelle/diverter configuration with the flat-plate boundary layer. At the lowest h(sub n)/delta tested, the diverter wedge half-angle had virtually no effect on the nacelle/diverter drag. However, as h(sub n)/delta increased, the nacelle/diverter drag increased as diverter wedge half-angle increased.

    Description: Water droplet trajectories within the NASA Lewis Research Center's Icing Research Tunnel (IRT) were studied through computer analysis. Of interest was the influence of the wind tunnel contraction and wind tunnel model blockage on the water droplet trajectories. The computer analysis was carried out with a program package consisting of a three-dimensional potential panel code and a three-dimensional droplet trajectory code. The wind tunnel contraction was found to influence the droplet size distribution and liquid water content distribution across the test section from that at the inlet. The wind tunnel walls were found to have negligible influence upon the impingement of water droplets upon a wing model.

    Description: This document outlines the tests performed to make aerodynamic force and torque measurements on the SOFIA wind tunnel model telescope. These tests were performed during the SOFIA 2 wind tunnel test in the 14 ft wind tunnel during the months of June through August 1994. The test was designed to measure the dynamic cross elevation moment acting on the SOFIA model telescope due to aerodynamic loading. The measurements were taken with the telescope mounted in an open cavity in the tail section of the SOFIA model 747. The purpose of the test was to obtain an estimate of the full scale aerodynamic disturbance spectrum, by scaling up the wind tunnel results (taking into account differences in sail area, air density, cavity dimension, etc.). An estimate of the full scale cross elevation moment spectrum was needed to help determine the impact this disturbance would have on the telescope positioning system requirements. A model of the telescope structure, made of a light weight composite material, was mounted in the open cavity of the SOFIA wind tunnel model. This model was mounted via a force balance to the cavity bulkhead. Despite efforts to use a 'stiff' balance, and a lightweight model, the balance/telescope system had a very low resonant frequency (37 Hz) compared to the desired measurement bandwidth (1000 Hz). Due to this mechanical resonance of the balance/telescope system, the balance alone could not provide an accurate measure of applied aerodynamic force at the high frequencies desired. A method of measurement was developed that incorporated accelerometers in addition to the balance signal, to calculate the aerodynamic force.

    Description: The work reported here pertains only to the first year of research for a three year proposal period. As a prelude to this two dimensional interface element, the one dimensional element was tested and errors were discovered in the code for built-up structures and curved interfaces. These errors were corrected and the benchmark Boeing composite crown panel was analyzed successfully. A study of various splines led to the conclusion that cubic B-splines best suit this interface element application. A least squares approach combined with cubic B-splines was constructed to make a smooth function from the noisy data obtained with random error in the coordinate data points of the Boeing crown panel analysis. Preliminary investigations for the formulation of discontinuous 2-D shell and 3-D solid elements were conducted.

    Description: Test flights were conducted to evaluate the capability of Differential Global Positioning System (DGPS) to provide the accuracy and integrity required for International Civil Aviation Organization (ICAO) Category (CAT) III precision approach and landings. These test flights were part of a Federal Aviation Administration (FAA) program to evaluate the technical feasibility of using DGPS based technology for CAT III precision approach and landing applications. An IAI Westwind 1124 aircraft (N24RH) was equipped with DGPS receiving equipment and additional computing capability provided by E-Systems. The test flights were conducted at NASA Ames Research Center's Crows Landing Flight Facility, Crows Landing, California. The flight test evaluation was based on completing 100 approaches and landings. The navigation sensor error accuracy requirements were based on ICAO requirements for the Microwave Landing System (MLS). All of the approaches and landings were evaluated against ground truth reference data provided by a laser tracker. Analysis of these approaches and landings shows that the E-Systems DGPS system met the navigation sensor error requirements for a successful approach and landing 98 out of 100 approaches and landings, based on the requirements specified in the FAA CAT III Level 2 Flight Test Plan. In addition, the E-Systems DGPS system met the integrity requirements for a successful approach and landing or stationary trial for all 100 approaches and landings and all ten stationary trials, based on the requirements specified in the FAA CAT III Level 2 Flight Test Plan.

    Description: Low-speed wind-tunnel tests were conducted in the Langley 12-Foot Low-Speed Tunnel on a model of the Boeing Multirole Fighter (BMRF) aircraft. This single-seat, single-engine configuration was intended to be an F-16 replacement that would incorporate many of the design goals and advanced technologies of the F-22. Its mission requirements included supersonic cruise without afterburner, reduced observability, and the ability to attack both air-to-air and air-to-ground targets. So that it would be effective in all phases of air combat, the ability to maneuver at angles of attack up to and beyond maximum lift was also desired. Traditional aerodynamic yaw controls, such as rudders, are typically ineffective at these higher angles of attack because they are usually located in the wake from the wings and fuselage. For this reason, this study focused on investigating forebody-mounted controls that produces yawing moments by modifying the strong vortex flowfield being shed from the forebody at high angles of attack. Two forebody strakes were tested that varied in planform and chordwise location. Various patterns of porosity in the forebody skin were also tested that differed in their radial coverage and chordwise location. The tests were performed at a dynamic pressure of 4 lb/ft(exp 2) over an angle-of-attack range of -4 deg to 72 deg and a sideslip range of -10 deg to 10 deg. Static force data, static pressures on the surface of the forebody, and videotapes of flow-visualization using laser-illuminated smoke were obtained.

This report contains pressure data which document effects of wing configuration and free-stream conditions on wing pressure distributions. The untwisted wing incorporated a full-span, leading-edge Krueger flap and a full-span, single-slotted trailing-edge flap. The trailing-edge flap was tested at a deflection angle of 40 degrees and the Krueger flap at a deflection of 55 degrees. Three wing configurations were tested: cruise, trailing-edge flap only, and Knueger flap and trailing-edge flap deployed. Tests were conducted at free-stream dynamic pressures of 15, 30 and 60 psf, with corresponding chord Reynolds numbers of 1.22 to 2.11 million and Mach numbers of 0.12 to 0.20. Angles of attack presented range from 0 to 20 degrees, depending on wing configuration. The data are presented without analysis.

    Description: This report addresses the development of a multidisciplinary optimization procedure using an efficient semi-analytical sensitivity analysis technique and multilevel decomposition for the design of aerospace vehicles. A semi-analytical sensitivity analysis procedure is developed for calculating computational grid sensitivities and aerodynamic design sensitivities. Accuracy and efficiency of the sensitivity analysis procedure is established through comparison of the results with those obtained using a finite difference technique. The developed sensitivity analysis technique are then used within a multidisciplinary optimization procedure for designing aerospace vehicles. The optimization problem, with the integration of aerodynamics and structures, is decomposed into two levels. Optimization is performed for improved aerodynamic performance at the first level and improved structural performance at the second level. Aerodynamic analysis is performed by solving the three-dimensional parabolized Navier Stokes equations. A nonlinear programming technique and an approximate analysis procedure are used for optimization. The proceduredeveloped is applied to design the wing of a high speed aircraft. Results obtained show significant improvements in the aircraft aerodynamic and structural performance when compared to a reference or baseline configuration. The use of the semi-analytical sensitivity technique provides significant computational savings.

    Description: The effectiveness of steady and pulsed blowing as a method of controlling delta wing vortices during ramp pitching has been investigated in flow visualization experiments conducted in a water tunnel. The recessed angled spanwise blowing technique was utilized for vortex manipulation. This technique was implemented on a beveled 60 delta wing using a pair of blowing ports located beneath the vortex core at 40% chord. The flow was injected primarily in the spanwise direction but was also composed of a component normal to the wing surface. The location of vortex burst was measured as a function of blowing intensity and pulsing frequency under static conditions, and the optimum blowing case was applied at three different wing pitching rates. Experimental results have shown that, when the burst location is upstream of the blowing port, pulsed blowing delays vortex breakdown in static and dynamic cases. Dynamic tests verified the existence of a hysteresis effect and demonstrated the improvements offered by pulsed blowing over both steady blowing and no-blowing scenarios. The application of blowing, at the optimum pulsing frequency, made the vortex breakdown location comparable in static and ramp pitch-up conditions.

    Description: Primarily an experimental effort, this study focuses on the velocity and vorticity fields in the near wake of a hovering rotor. Drag terminology is reviewed, and the theory for separately determining the profile-and-induced-drag components from wake quantities is introduced. Instantaneous visualizations of the flow field are used to center the laser velocimeter (LV) measurements on the vortex core and to assess the extent of the positional mandering of the trailing vortex. Velocity profiles obtained at different rotor speeds and distances behind the rotor blade clearly indicate the position, size, and rate of movement of the wake sheet and the core of the trailing vortex. The results also show the distribution of vorticity along the wake sheet and within the trailing vortex.

    Description: This report summarizes the research performed by North Carolina State University and NASA Ames Research Center under Cooperative Agreement NCA2-719, 'Numerical Simulation of Supersonic and Hypersonic Inlet Flow Fields". Four distinct rotated upwind schemes were developed and investigated to determine accuracy and practicality. The scheme found to have the best combination of attributes, including reduction to grid alignment with no rotation, was the cell centered non-orthogonal (CCNO) scheme. In 2D, the CCNO scheme improved rotation when flux interpolation was extended to second order. In 3D, improvements were less dramatic in all cases, with second order flux interpolation showing the least improvement over grid aligned upwinding. The reduction in improvement is attributed to uncertainty in determining optimum rotation angle and difficulty in performing accurate and efficient interpolation of the angle in 3D. The CCNO rotational technique will prove very useful for increasing accuracy when second order interpolation is not appropriate and will materially improve inlet flow solutions.

    Description: Aeroelastic stability analyses have been performed for the MOD-5A blade/aileron system. Various configurations having different aileron torsional stiffness, mass unbalance, and control system damping have been investigated. The analysis was conducted using a code recently developed by the General Electric Company - AILSTAB. The code extracts eigenvalues for a three degree of freedom system, consisting of: (1) a blade flapwise mode; (2) a blade torsional mode; and (3) an aileron torsional mode. Mode shapes are supplied as input and the aileron can be specified over an arbitrary length of the blade span. Quasi-steady aerodynamic strip theory is used to compute aerodynamic derivatives of the wing-aileron combination as a function of spanwise position. Equations of motion are summarized herein. The program provides rotating blade stability boundaries for torsional divergence, classical flutter (bending/torsion) and wing/aileron flutter. It has been checked out against fixed-wing results published by Theodorsen and Garrick. The MOD-5A system is stable with respect to divergence and classical flutter for all practical rotor speeds. Aileron torsional stiffness must exceed a minimum critical value to prevent aileron flutter. The nominal control system stiffness greatly exceeds this minimum during normal operation. The basic system, however, is unstable for the case of a free (or floating) aileron. The instability can be removed either by the addition of torsional damping or mass-balancing the ailerons. The MOD-5A design was performed by the General Electric Company, Advanced Energy Program Department under Contract DEN3-153 with NASA Lewis Research Center and sponsored by the Department of Energy.

    Description: A method has been developed to accurately compute the viscous flow in three-dimensional (3-D) enclosures. This method is the 3-D extension of a two-dimensional (2-D) method developed for the calculation of flow over airfoils. The 2-D method has been tested extensively and has been shown to accurately reproduce experimental results. As in the 2-D method, the 3-D method provides for the non-iterative solution of the incompressible Navier-Stokes equations by means of a fully coupled implicit technique. The solution is calculated on a body fitted computational mesh incorporating a staggered grid methodology. In the staggered grid method, the three components of vorticity are defined at the centers of the computational cell sides, while the velocity components are defined as normal vectors at the centers of the computational cell faces. The staggered grid orientation provides for the accurate definition of the vorticity components at the vorticity locations, the divergence of vorticity at the mesh cell nodes and the conservation of mass at the mesh cell centers. The solution is obtained by utilizing a fractional step solution technique in the three coordinate directions. The boundary conditions for the vorticity and velocity are calculated implicitly as part of the solution. The method provides for the non-iterative solution of the flow field and satisfies the conservation of mass and divergence of vorticity to machine zero at each time step. To test the method, the calculation of simple driven cavity flows have been computed. The driven cavity flow is defined as the flow in an enclosure driven by a moving upper plate at the top of the enclosure. To demonstrate the ability of the method to predict the flow in arbitrary cavities, results will he shown for both cubic and curved cavities.

    Description: An effort to understand and control the unsteady separated flow associated with the dynamic stall of airfoils was funded for three years through the NASA cooperative agreement program. As part of this effort a substantial data base was compiled detailing the effects various parameters have on the development of the dynamic stall flow field. Parameters studied include Mach number, pitch rate, and pitch history, as well as Reynolds number (through two different model chord lengths) and the condition of the boundary layer at the leading edge of the airfoil (through application of surface roughness). It was found for free stream Mach numbers as low as 0.4 that a region of supersonic flow forms on the leading edge of the suction surface of the airfoil at moderate angles of attack. The shocks which form in this supersonic region induce boundary-layer separation and advance the dynamic stall process. Under such conditions a supercritical airfoil profile is called for to produce a flow field having a weaker leading-edge pressure gradient and no leading-edge shocks. An airfoil having an adaptive-geometry, or dynamically deformable leading edge (DDLE), is under development as a unique active flow-control device. The DDLE, formed of carbon-fiber composite and fiberglass, can be flexed between a NACA 0012 profile and a supercritical profile in a controllable fashion while the airfoil is executing an angle-of-attack pitch-up maneuver. The dynamic stall data were recorded using point diffraction interferometry (PDI), a noninvasive measurement technique. A new high-speed cinematography system was developed for recording interferometric images. The system is capable of phase-locking with the pitching airfoil motion for real-time documentation of the development of the dynamic stall flow field. Computer-aided image analysis algorithms were developed for fast and accurate reduction of the images, improving interpretation of the results.

    Description: A numerical scheme utilizing a chimera zonal grid approach for solving the full potential equation in two spatial dimensions is described. Within each grid zone a fully-implicit approximate factorization scheme is used to advance the solution one interaction. This is followed by the explicit advance of all common zonal grid boundaries using a bilinear interpolation of the velocity potential. The presentation is highlighted with numerical results simulating the flow about a two-dimensional, nonlifting, circular cylinder. For this problem, the flow domain is divided into two parts: an inner portion covered by a polar grid and an outer portion covered by a Cartesian grid. Both incompressible and compressible (transonic) flow solutions are included. Comparisons made with an analytic solution as well as single grid results indicate that the chimera zonal grid approach is a viable technique for solving the full potential equation.

    Description: Distributions of static pressure coefficient over the afterbody and axisymmetric nozzles of a generic, twin-tail twin-engine fighter were obtained in the Langley 16-Foot Transonic Tunnel. The longitudinal positions of the vertical and horizontal tails were varied for a total of six aft-end configurations. Static pressure coefficients were obtained at Mach numbers between 0.6 and 1.2, angles of attack between 0 deg and 8 deg, and nozzle pressure ratios ranging from jet-off to 8. The results of this investigation indicate that the influence of the vertical and horizontal tails extends beyond the vicinity of the tail-afterbody juncture. The pressure distribution affecting the aft-end drag is influenced more by the position of the vertical tails than by the position of the horizontal tails. Transonic tail-interference effects are seen at lower free-stream Mach numbers at positive angles of attack than at an angle of attack of 0 deg.

    Description: The National Aeronautics and Space Administration and the Defense Research Agency (United Kingdom) have ongoing experimental research programs in rotary-flow aerodynamics. A cooperative effort between the two agencies is currently underway to collect an extensive database for the development of high angle of attack computational methods to predict the effects of Reynolds number on the forebody flowfield at dynamic conditions, as well as to study the use of low Reynolds number data for the evaluation of high Reynolds number characteristics. Rotary balance experiments, including force and moment and surface pressure measurements, were conducted on circular and rectangular aftbodies with hemispherical and ogive noses at the Bedford and Farnborough wind tunnel facilities in the United Kingdom. The bodies were tested at 60 and 90 deg angle of attack for a wide range of Reynolds numbers in order to observe the effects of laminar, transitional, and turbulent flow separation on the forebody characteristics when rolling about the velocity vector.

    Description: A wind-tunnel investigation of the effectiveness of an aerodynamic yaw controller mounted on the lower surface of a shuttle orbiter model body flap was conducted in the Langley 31-Inch Mach 10 Tunnel. The controller consisted of a 60 deg delta fin mounted perpendicular to the body flap lower surface and yawed 30 deg to the free stream direction. The control was tested at angles of attack from 20 deg to 40 deg at zero sideslip for a Reynolds number based on wing mean aerodynamic chord of 0.66 x 10(exp 6). The aerodynamic and control effectiveness characteristics are presented along with an analysis of the effectiveness of the controller in making a bank maneuver for Mach 18 flight conditions. The controller was effective in yaw and produced a favorable rolling moment. The analysis showed that the controller was as effective as the reaction control system in making the bank maneuver. These results warrant further studies of the aerodynamic/aerothermodynamic characteristics of the control concept for application to future transportation vehicles.

    Description: The approach to carrying out multi-discipline aerospace design studies in the future, especially in massively parallel computing environments, comprises of choosing (1) suitable solvers to compute solutions to equations characterizing a discipline, and (2) efficient optimization methods. In addition, for aerodynamic optimization problems, (3) smart methodologies must be selected to modify the surface shape. In this research effort, a 'direct' optimization method is implemented on the Cray C-90 to improve aerodynamic design. It is coupled with an existing implicit Navier-Stokes solver, OVERFLOW, to compute flow solutions. The optimization method is chosen such that it can accomodate multi-discipline optimization in future computations. In the work , however, only single discipline aerodynamic optimization will be included.

    Description: Modeling enhancements made to a radial-inflow turbine conceptual design code are documented in this report. A stator-endwall clearance-flow model was added for use with pivoting vanes. The rotor calculations were modified to account for swept blades and splitter blades. Stator and rotor trailing-edge losses and a vaneless-space loss were added to the loss model. Changes were made to the disk-friction and rotor-clearance loss calculations. The loss model was then calibrated based on experimental turbine performance. A complete description of code input and output along with sample cases are included in the report.

    Description: Internal fluid flows are subject not only to self-sustained oscillations of the purely hydrodynamic type but also to the coupling of the instability with the acoustic mode of the surrounding cavity. This situation is common to turbomachinery, since flow instabilities are confined within a flow path where the acoustic wavelength is typically smaller than the dimensions of the cavity and flow speeds are low enough to allow resonances. When acoustic coupling occurs, the fluctuations can become so severe in amplitude that it may induce structural failure of engine components. The potential for catastrophic failure makes identifying flow-induced noise and vibration sources a priority. In view of the complexity of these types of flows, this report was written with the purpose of presenting many of the methods used to compute frequencies for self-sustained oscillations. The report also presents the engineering formulae needed to calculate the acoustic resonant modes for ducts and cavities. Although the report is not a replacement for more complex numerical or experimental modeling techniques, it is intended to be used on general types of flow configurations that are known to produce self-sustained oscillations. This report provides a complete collection of these models under one cover.

    Description: This study was conducted to experimentally characterize the flow field created by the interaction of a single-expansion ramp-nozzle (SERN) flow with a hypersonic external stream. Data were obtained from a generic nozzle/afterbody model in the 3.5 Foot Hypersonic Wind Tunnel at the NASA Ames Research Center, in a cooperative experimental program involving Ames and McDonnell Douglas Aerospace. The model design and test planning were performed in close cooperation with members of the Ames computational fluid dynamics (CFD) team for the National Aerospace Plane (NASP) program. This paper presents experimental results consisting of oil-flow and shadow graph flow-visualization photographs, afterbody surface-pressure distributions, rake boundary-layer measurements, Preston-tube skin-friction measurements, and flow field surveys with five-hole and thermocouple probes. The probe data consist of impact pressure, flow direction, and total temperature profiles in the interaction flow field.

    Description: A methodology is described for computing viscous flows of air and sulfur hexafluoride (SF6). The basis is an existing flow solver that calculates turbulent flows in two dimensions on unstructured triangular meshes. The solver has been modified to incorporate the thermodynamic model for SF6 and used to calculate the viscous flow over two multielement airfoils that have been tested in a wind tunnel with air as the test medium. Flows of both air and SF6 at a free-stream Mach number of 0.2 and a Reynolds number of 9 x 10(exp 6) are computed for a range of angles of attack corresponding to the wind-tunnel test. The computations are used to investigate the suitability of SF6 as a test medium in wind tunnels and are a follow-on to previous computations for single-element airfoils. Surface-pressure, lift, and drag coefficients are compared with experimental data. The effects of heavy gas on the details of the flow are investigated based on computed boundary-layer and skin-friction data. In general, the predictions in SF6 vary little from those in air. Within the limitations of the computational method, the results presented are sufficiently encouraging to warrant further experiments.

    Description: It is well known in the aerodynamic field that pressure distribution measurement over the surface of an aircraft model is a problem in experimental aerodynamics. For one thing, a continuous pressure map can not be obtained with the current experimental methods since they are discrete. Therefore, interpolation or CFD methods must be used for a more complete picture of the phenomenon under study. For this study, a new technique was investigated which would provide a continuous pressure distribution over the surface under consideration. The new method is pressure sensitive paint. When pressure sensitive paint is applied to an aerodynamic surface and placed in an operating wind-tunnel under appropriate lighting, the molecules luminesce as a function of the local pressure of oxygen over the surface of interest during aerodynamic flow. The resulting image will be brightest in the areas of low pressure (low oxygen concentration), and less intense in the areas of high pressure (where oxygen is most abundant on the surface). The objective of this investigation was to use pressure sensitive paint samples from McDonnell Douglas (MDD) for calibration purpose in order to assess the response of the paint under appropriate lighting and to use the samples over a flat plate/conical fin mounted at 75 degrees from the center of the plate in order to study the shock/boundary layer interaction at Mach 6 in the Von Karman wind-tunnel. From the result obtained it was concluded that temperature significantly affects the response of the paint and should be given the uppermost attention in the case of hypersonic flows. Also, it was found that past a certain temperature threshold, the paint intensity degradation became irreversible. The comparison between the pressure tap measurement and the pressure sensitive paint showed the right trend. However, there exists a shift when it comes to the actual value. Therefore, further investigation is under way to find the cause of the shift.

    Description: Longitudinal characteristics and wing-section pressure distributions are compared for the EA-6B airplane with and without airfoil modifications. The airfoil modifications were designed to increase low-speed maximum lift for maneuvering, while having a minimal effect on transonic performance. Section contour changes were confined to the leading-edge slat and trailing-edge flap regions of the wing. Experimental data are analyzed from tests in the Langley 16-Foot Transonic Tunnel on the baseline and two modified wing-fuselage configurations with the slats and flaps in their retracted positions. Wing modification effects on subsonic and transonic performance are seen in wing-section pressure distributions of the various configurations at similar lift coefficients. The modified-wing configurations produced maximum lift coefficients which exceeded those of the baseline configuration at low-speed Mach numbers (0.300 and 0.400). This benefit was related to the behavior of the wing upper surface leading-edge suction peak and the behavior of the trailing-edge pressure. At transonic Mach numbers (0.725 to 0.900), the wing modifications produced a somewhat stronger nose-down pitching moment, a slightly higher drag at low-lift levels, and a lower drag at higher lift levels.

    Description: This report describes the aerodynamics model used in a simulation model of an advanced short takeoff and vertical landing (ASTOVL) lift-fan fighter aircraft. The simulation model was developed for use in piloted evaluations of transition and hover flight regimes, so that only low speed (M approximately 0.2) aerodynamics are included in the mathematical model. The aerodynamic model includes the power-off aerodynamic forces and moments and the propulsion system induced aerodynamic effects, including ground effects. The power-off aerodynamics data were generated using the U.S. Air Force Stability and Control Digital DATCOM program and a NASA Ames in-house graphics program called VORVIEW which allows the user to easily analyze arbitrary conceptual aircraft configurations using the VORLAX program. The jet-induced data were generated using the prediction methods of R. E. Kuhn et al., as referenced in this report.
