    Correction factory techniques for improving aerodynamic prediction methods (1976)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A method for correcting discrete element lifting surface theory to reflect given experimental data is presented. Theoretical pressures are modified such that imposed constraints are satisfied while minimizing the changes to the pressures. Several types of correction procedures are presented and correlated; (1) scaling of pressures; (2) scaling of downwash values; and (3) addition of an increment to the downwash that is proportioned to pressure. Some special features are included in these methods and they include: (1) consideration of experimental data from multiple deflection modes, (2) limitation of the amplitudes of the correction factors, and (3) the use of correction factor mode shapes. These methods are correlated for cases involving all three Mach Number ranges using a FORTRAN IV computer program. Subsonically, a wing with an oscillating partial span control surface and a wing with a leading edge droop are presented. Transonically a two-dimensional airfoil with an oscillating flap is considered. Supersonically an arrow wing with and without camber is analyzed. In addition to correction factor methods an investigation is presented dealing with a new simplified transonic modification of the two-dimensional subsonic lifting surface theory. Correlations are presented for an airfoil with an oscillating flap.

    Low-speed wind tunnel investigation of an advanced supersonic cruise arrow-wing configuration (1977)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A preliminary assessment of possible means for improving the low speed aerodynamic characteristics of advanced supersonic cruise arrow wing configurations and to extend the existing data base of such configurations has been made. Principle configuration variables included wing-leading and trailing-edge flap deflection, fuselage nose strakes, and engine exhaust nozzle deflection. Results showed that deflecting the wing leading edge apex flaps downward provided improved longitudinal stability but resulted in reduced directional stability. The model exhibited relatively low values of directional stability over the operational angle of attack range and experienced large asymmetric yawing moments at high angles of attack. The use of nose strakes was found to be effective in increasing the directional stability and eliminating the asymmetric yawing moment.

    Notes: Es wurde eine Theorie der Elektrolyse von Kryolith-Tonerde-schmelzen entwickelt. Es wurde der Nechanismus des Stromdurchganges und der Vorgänge an den Elektrolyten gezeigt. Bei der Elektrolyse der genannten Schmelzen erscheint an der Anode freies AI2F6, und an der Kathode entsteht das Aluminat Na3A103. Es ist zweckmäßig, mit Kryolith zu arbeiten, der einen Überschuß an Fluoraluminium enthält. Arbeitet man in neuen Bädern selbst mit Kryolith von normaler Zusammensetzung, so kann man mitunter (trotz der Verdampfung eines Teiles Al2F6 an der Anode) eine Anreicherung des Elektrolyten an Fluoraluminium beobachten. Diese Erscheinung läßt sich darauf zurückführen, daß der Kohlebeschlag des Bades das Aluminat vorzugsweise einsaugt. Durch Elektrolyse des Aluminats läßt sich die Bildung von metallischem Natrium in der Kohlenmasse erklären.

    A versatile all-glass GC/MS interface for capillary columns (1979)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 2 (1979), S. 225-228 
    Details
    ISSN: 0935-6304
    Keywords: GC/MS Interface ; Glass ; Open split ; HMDS glass surface deactivation ; Glass capillary columns ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A new all-glass interface for GC/MS designed to fully exploit the potential of glass capillary columns is described. The system works in the open split mode and has high versatility with respect to column changing. It is especially suitable for mass spectrometers, which are not exclusively dedicated to GC/MS work. Two chromatograms illustrate the properties of the described interface.
