    Effects of Nose Radius and Extreme Cooling on Boundary-Layer Transition for Three Smooth 15-Cone-Cylinders in Free Flight at Mach Numbers to 8.50 (1959)
    In:  CASI
    Details
    Publication Date: 2019-05-11
    Description: Three highly polished 15- included- angle cone- cylinders with hemispherical tips of several diameters ( 2, 3, and 4 in.) have been flown in order to obtain boundary- layer transition data at very low wall to local stream temperature ratios, and heat- transfer data. All surfaces had a 2-microinch average roughness height. Laminar flow existed over the entire hemispherical nose of the 2- and 3-inch-tip- diameter models throughout the complete flight history. Extreme cooling to wall to local stream temperature ratios at the sonic point as low as 0.20 did not cause transition on the nose for diameters as large as 3 inches. However, extreme cooling did cause early transition on the 4-inch model where it appears probable that transition occurred forward of the 45 station at a wall to local stream temperature ratio of about 0.26. Variations in tip diameter influenced transition downstream of the nose under conditions of extreme cooling. The 2-inch- tip model was laminar at all cone- cylinder stations at temperature ratios as low as 0.32 whereas the 3- and 4-inch-tip models were turbulent at the same local flow conditions but at higher wall to local temperature ratios. Transition on the cone and cylinder of the 3- and 4-inch- tip bodies appeared to be sensitive to local Mach number, and occurred at higher local temperature ratios when values of local Mach number were higher. Increasing the nose diameter from 2 to 3 inches significantly changed the local flow conditions for which laminar flow existed on the cone- cylinder afterbody. However, a further increase in tip size t o a 4-inch diameter had no discernable effect on the local flow conditions at transition. The transition results of the 3- and 4-inch-nose-diameter smooth bodies are similar to those observed on a 7/8-inch-nose-diameter body with roughened surfaces. Turbulent boundary layers resulted in both cases at very low wall to local stream temperature ratios. Both laminar and turbulent heat-transfer data were in good agreement with theoretical Stanton numbers when heat-transfer reduction due to tip blunting was considered.

    Lift and Drag of a Swept-Wing Fighter Airplane at Transonic and Supersonic Speeds (1959)
    In:  CASI
    Details
    Publication Date: 2019-05-11
    Description: A flight investigation was made of the lift and drag of a sweptwing fighter airplane in the basic configuration and in a slats-locked-closed configuration over a Mach number range from about 0.63 to about 1.44. At a nominal lift coefficient of 0.1 negligible drag-coefficient difference existed between the two configurations over a comparable Mach number and altitude range. For the basic configuration at zero lift the supersonic drag level was about three times as great as the subsonic drag level, which was about 0.01, whereas the drag-due-to-lift factor increased about 137 percent over the test Mach number range. At comparable Mach numbers the high-altitude data produced a larger lift-curve slope and showed a more pronounced variation of lift-curve slope in the transonic region than did the low-altitude data. For the high-altitude data the lift-curve slope at a Mach number of 1.44 was approximately 62 percent of the value at a Mach number of 0.9.

    NASA Research Bearing on Jet Engine Reliability (1959)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: Turbojet engine reliability has long been an intense interest to the military users of this type of aircraft propulsion. With the recent inauguration of commercial jet transport this subject has assumed a new dimension of importance. In January l96 the Lewis Research Center of the NASA (then the MACA) published the results of an extensive study on the factors that affect the opera- center dot tional reliability of turbojet engines (ref. 1). At that time the report was classified Confidential. In July l98 this report was declassified. It is thus appropriate at this time to present some of the highlights of the studies described in the NASA report. In no way is it intended to outline the complete contents of the report; rather it is hoped to direct attention to it among those who are center dot directly concerned with this problem. Since the publication of our study over three years ago, the NASA has completed a number of additional investigations that bear significantly on this center dot subject. A second object of this paper, therefore, is to summarize the results of these recent studies and to interpret their significance in relation to turbojet operational reliability.

    Investigation of Low-Subsonic Flight Characteristics of a Model of a Flat-Bottom Hypersonic Boost-Glide Configuration Having a 78 deg Delta Wing (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: An investigation of the low-subsonic stability and control characteristics of a model of a flat-bottom hypersonic boost-glide configuration having 78 deg sweep of the leading edge has been made in the Langley full-scale tunnel. The model was flown over an angle-of-attack range from 10 to 35 deg. Static and dynamic force tests were made in the Langley free-flight tunnel. The investigation showed that the longitudinal stability and control characteristics were generally satisfactory with neutral or positive static longitudinal stability. The addition of artificial pitch damping resulted in satisfactory longitudinal characteristics being obtained with large amounts of static instability. The most rearward center-of-gravity position for which sustained flights could be made either with or without pitch damper corresponded to the calculated maneuver point. The lateral stability and control characteristics were satisfactory up to about 15 deg angle of attack. The damping of the Dutch roll oscillation decreased with increasing angle of attack; the oscillation was about neutrally stable at 20 deg angle of attack and unstable at angles of attack of about 25 deg and above. Artificial damping in roll greatly improved the lateral characteristics and resulted in flights being made up to 35 deg angle of attack.

    Analysis of Acceleration, Airspeed, and Gust-Velocity Data From a Four-Engine Transport Airplane Operating Over a Northwestern United States Alaska Route (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: Acceleration, airspeed, and altitude data obtained with an NACA VGH recorder from a four-engine commercial transport airplane operating over a northwestern United States-Alaska route were evaluated to determine the magnitude and frequency of occurrence of gust and maneuver accelerations., operating airspeeds, and gust velocities. The results obtained were then compared with the results previously reported in NACA Technical Note 3475 for two similar airplanes operating over transcontinental routes in the United States. No large variations in the gust experience for the three operations were noted. The results indicate that the gust-load experience of the present operation closely approximated that of the central transcontinental route in the United States with which it is compared and showed differences of about 4 to 1 when compared with that of the southern transcontinental route in the United States. In general, accelerations due to gusts occurred much more frequently than those due to operational maneuvers. At a measured normal-acceleration increment of 0.5g, accelerations due to gusts occurred roughly 35 times more frequently than those due to operational maneuvers.

    An Analysis of Flight-Test Measurements of the Wing Structural Deformations in Rough Air of a Large Flexible Swept-Wing Airplane (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: An analysis is made of wing deflection and streamwise twist measurements in rough-air flight of a large flexible swept-wing bomber. Random-process techniques are employed in analyzing the data in order to describe the magnitude and characteristics of the wing deflection and twist responses to rough air. Power spectra and frequency-response functions for the wing deflection and twist responses at several spanwise stations are presented. The frequency-response functions describe direct and absolute response characteristics to turbulence and provide a convenient basis for assessing analytic calculation techniques. The wing deformations in rough air are compared with the expected deformations for quasi-static loadings of the same magnitude, and the amplifications are determined. The results obtained indicate that generally the deflections are amplified by a small amount, while the streamwise twists are amplified by factors of the order of 2.0. The magnitudes of both the deflection velocities and the twist angles are shown to have significant effects on the local angles of attack at the various stations and provide the main source of aerodynamic loading, particularly at frequencies in the vicinity of the first wing-vibration mode.

    Effect of Cascade Parameters on Rotating Stall (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: Analysis of the vortex model proposed by Kriebel, Seidel, and Schwind shows this representation of rotating stall satisfies, at least approximately, the requirements at the cascade. Cascade-parameter-variation effects on rotating stall were studied in a circular cascade and single-stage compressor. Modification of the single-stage compressor stopped the rotating-stall pattern and permitted observation of the pressure and velocity distribution around the annulus. Closer observation might be possible with proper flow-visualization techniques, such as a water pump.

    Effect of Stator and Rotor Aspect Ratio on Transonic-Turbine Performance (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: The effect of stator and rotor aspect ratio on transonic-turbine performance was experimentally investigated. The stator aspect ratios covered were 1.6. 0.8, and 0.4, while the rotor aspect ratios investigated were 1.46 and 0.73. It was found that the observed variation in turbine design-point efficiency was negligible. Thus, within the range of aspect ratio investigated, these results verify for turbines operating in the transonic flow range the finding of a reference report, which showed analytically that, if blade shape and solidity are held constant, the aspect ratio may be varied over a wide range without appreciable change in turbine efficiency.

    Experimental Evaluation of Cermet Turbine Stator Blades for Use at Elevated Gas Temperatures (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: The suitability of cermets for turbine stator blades of a modified turbojet engine was determined at an average turbine-inlet-gas temperature of 2000 F. Such an increase in temperature would yield a premium in thrust from a service engine. Because the cermet blades require no cooling, all the available compressor bleed air could be used to cool a turbine made from conventional ductile alloys. Cermet blades were first run in 100-hour endurance tests at normal gas temperatures in order to evaluate two methods for mounting them. The elevated gas-temperature test was then run using the method of support considered best for high-temperature operation. After 52 hours at 2000 F, one of the group of four cermet blades fractured probably because of end loads resulting from thermal distortion of the spacer band of the nozzle diaphragm. Improved design of a service engine would preclude this cause of premature failure.

    The Effect of Lower Surface Spoilers on the Transonic Trim Change of a Wind-Tunnel Model of a Fighter Airplane Having a Modified Delta Wing (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: In an attempt to find an aerodynamic means of counteracting the transonic trim change of a fighter airplane, lower surface spoilers were tested on a 0.055-scale wind-tunnel model. The Mach number range of the tests was 0.8 to 1.2 at Reynolds numbers of approximately 4 million. Although the spoilers produced a moderate decrease in the trim change at low altitudes, they also produced a large increase in drag. Pressure-distribution tests with external fuel tanks showed large pressure changes on the lower surface of the wing due to the tanks.

    Air-Cooled Turbine Blades with Tip Cap For Improved Leading-Edge Cooling (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: An investigation was conducted in a modified turbojet engine to determine the cooling characteristics of the semistrut corrugated air- cooled turbine blade and to compare and evaluate a leading-edge tip cap as a means for improving the leading-edge cooling characteristics of cooled turbine blades. Temperature data were obtained from uncapped air-cooled blades (blade A), cooled blades with the leading-edge tip area capped (blade B), and blades with slanted corrugations in addition to leading-edge tip caps (blade C). All data are for rated engine speed and turbine-inlet temperature (1660 F). A comparison of temperature data from blades A and B showed a leading-edge temperature reduction of about 130 F that could be attributed to the use of tip caps. Even better leading-edge cooling was obtained with blade C. Blade C also operated with the smallest chordwise temperature gradients of the blades tested, but tip-capped blade B operated with the lowest average chordwise temperature. According to a correlation of the experimental data, all three blade types 0 could operate satisfactorily with a turbine-inlet temperature of 2000 F and a coolant flow of 3 percent of engine mass flow or less, with an average chordwise temperature limit of 1400 F. Within the range of coolant flows investigated, however, only blade C could maintain a leading-edge temperature of 1400 F for a turbine-inlet temperature of 2000 F.

    Evaluation of the Levy Method as Applied to Vibrations of a 45 deg Delta Wing (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: The Levy method which deals with an idealized structure was used to obtain the natural modes and frequencies of a large-scale built-up 45 deg. delta wing. The results from this approach, both with and without the effects of transverse shear, were compared with the results obtained experimentally and also with those calculated by the Stein-Sanders method. From these comparisons it was concluded that the method as proposed by Levy gives excellent results for thin-skin delta wings, provided that corrections are made for the effect of transverse shear.

    An Experimental Investigation of a Triangular Wing of Aspect Ratio 2 and a Body Warped to be Trimmed at M = 2.24 (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: A cambered and twisted triangular wing of aspect ratio 2 in combination with a cambered body was investigated experimentally to determine the effectiveness of the camber in reducing the drag due to lift at trim at supersonic speeds. Four arrangements were tested comprising all combinations of a symmetrical and a cambered wing with a symmetrical and a cambered body. The camber shape investigated was derived by linearized lifting surface theory for triangular wings with sonic leading edges and satisfied the requirement that the wing be trimmed at the design Mach number and lift coefficient. The experimental results for the cambered wing and cambered body showed that the drag coefficient at trim was always greater, at the same lift coefficient, than that for the untrimmed symmetrical wing and body. The trim lift coefficient was positive and decreased with increasing Mach number. At the design Mach number of 2.24, the trim lift coefficient was somewhat lower and the drag coefficient was higher than values predicted by linearized lifting surface theory for the wing alone. A comparison of the trim lift-drag ratio of the cambered wing and cambered body with values obtained by trimming the symmetrical wing and symmetrical body either with a canard or a trailing-edge flap showed that, at approximately the design Mach number the cambered configuration developed a somewhat higher value than the trailing-edge flap configuration but a lower value than the canard configuration.

    Flight Behavior of the X-2 Research Airplane to a Mach Number of 3.20 and a Geometric Altitude of 126,200 Feet (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-17
    Description: The maximum Mach number and altitude capabilities of the Bell X-2 research airplane were achieved during a program conducted by the U.S. Air Force with Bell Aircraft Corp. providing operational support and the National Aeronautics and Space Administration providing instrumentation and advisory engineering assistance. A maximum geometric altitude of 126,200 feet was attained at a static pressure of 9.4 pounds per square foot and a dynamic pressure of 19.1 pounds per square foot. During the last flight of the airplane, a maximum Mach number of 3.20 was reached. The directionally divergent maneuver which terminated the final high Mach number flight was precipitated by the loss in directional stability that resulted from increasing the angle of attack. The yawing moment from the lateral control was sufficient to initiate the divergence and also to cause,, indirectly, rolling moments that were greater than the aileron capabilities of the airplane. The ensuing violent motions-resulting from inertial roll coupling caused the loss of the aircraft.

    Launch, Low-Speed, and Landing Characteristics Determined from the First Flight of the North American X-15 Research Airplane (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: The first flight of the North American X-15 research airplane was made on June 8, 1959. This was accomplished after completion of a series of captive flights with the X-15 attached to the B-52 carrier airplane to demonstrate the aerodynamic and systems compatibility of the X-15//B-52 combination and the X-15 subsystem operation. This flight was planned as a glide flight so that the pilot need not be concerned with the propulsion system. Discussions of the launch, low-speed maneuvering, and landing characteristics are presented, and the results are compared with predictions from preflight studies. The launch characteristics were generally satisfactory, and the X-15 vertical tail adequately cleared the B-52 wing cutout. The actual landing pattern and landing characteristics compared favorably with predictions, and the recommended landing technique of lowering the flaps and landing gear at a low altitude appears to be a satisfactory method of landing the X-15 airplane. There was a quantitative correlation between flight-measured and predicted lift-drag-ratio characteristics in the clean configuration and a qualitative correlation in the landing configuration. A longitudinal-controllability problem, which became severe in the landing configuration, was evident throughout the flight and, apparently, was aggravated by the sensitivity of the side-located control stick. In the low-to-moderate angle-of-attack range covered, the longitudinal and directional stability were indicated to be adequate.

    Subsonic Wing Loadings on a 45 deg Sweptback Wing and Body Combination at High Angles of Attack (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: A study has been made of the subsonic pressure distributions and loadings for a 45 deg sweptback-wing and body combination at angles of attack up to 36 deg. The wing had an aspect ratio of 5.5, a taper ratio of 0.53, and NACA 64A010 sections normal to the quarter-chord line and was mounted on a slender body of fineness ratio 12.5. Test results are presented for Mach numbers of 0.30 and 0.50 with corresponding Reynolds numbers of 1.5 and 2.0 million, respectively. The stall patterns and spanwise loadings at high angles of attack for the present model are correlated with those for other 45 deg sweptback wing and body combinations having aspect ratios between 4.0 and 8.0. A tentative approach is presented for extrapolating the Weissinger span-loading method to higher angles of attack, and for deriving the spanwise-load distributions for 45 deg sweptback wings at angles of attack above 20 deg. The investigation also included tests of the body in combination with only one panel of the swept wing. The problem of estimating the normal-force coefficient for the single panel at high angles of attack is considered.

    Publication Date: 2019-08-16
    Description: Results of a cyclic load test made by NASA on an EB-47E airplane are given. The test reported on is for one of three B-47 airplanes in a test program set up by the U. S. Air Force to evaluate the effect of wing structural reinforcements on fatigue life. As a result of crack development in the upper fuselage longerons of the other two airplanes in the program, a longeron and fuselage skin modification was incorporated early in the test. Fuselage strain-gage measurements made before and after the longeron modification and wing strain-gage measurements made only after wing reinforcement are summarized. The history of crack development and repair is given in detail. Testing was terminated one sequence short of the planned end of the program with the occurrence of a major crack in the lower right wing skin.

    The Effect of Lift-Drag Ratio and Speed on the Ability to Position a Gliding Aircraft for a Landing on a 5,000-Foot Runway (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: Flight tests were made to determine the capability of positioning a gliding airplane for a landing on a 5,000-foot runway with special reference to the gliding flight of a satellite vehicle of fixed configuration upon reentry into the earth's atmosphere. The lift-drag ratio and speed of the airplane in the glides were varied through as large a range as possible. The results showed a marked tendency to undershoot the runway when the lift-drag ratios were below certain values, depending upon the speed in the glide. A straight line dividing the successful approaches from the undershoots could be drawn through a lift-drag ratio of about 3 at 100 knots and through a lift-drag ratio of about 7 at 185 knots. Provision of a drag device would be very beneficial, particularly in reducing the tendency toward undershooting at the higher speeds.

    Evaluation of Several Approximate Methods for Calculating the Symmetrical Bending-Moment Response of Flexible Airplanes to Isotropic Atmospheric Turbulence (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: Several approximate procedures for calculating the bending-moment response of flexible airplanes to continuous isotropic turbulence are presented and evaluated. The modal methods (the mode-displacement and force-summation methods) and a matrix method (segmented-wing method) are considered. These approximate procedures are applied to a simplified airplane for which an exact solution to the equation of motion can be obtained. The simplified airplane consists of a uniform beam with a concentrated fuselage mass at the center. Airplane motions are limited to vertical rigid-body translation and symmetrical wing bending deflections. Output power spectra of wing bending moments based on the exact transfer-function solutions are used as a basis for the evaluation of the approximate methods. It is shown that the force-summation and the matrix methods give satisfactory accuracy and that the mode-displacement method gives unsatisfactory accuracy.

    Investigation of a 4.5-Inch-Mean-Diameter Two-Stage Axial-Flow Turbine Suitable for Auxiliary Power Drives (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: The design and experimental investigation of a 4.5-inch-mean-diameter two-stage turbine are presented herein and used to study the effect of size on the efficiency of turbines in the auxiliary power drive class. The results of the experimental investigation indicated that design specific work was obtained at design speed at a total-to-static efficiency of 0.639. At design pressure ratio, design static-pressure distribution through the turbine was obtained with an equivalent specific work output of 33.2 Btu per pound and an efficiency of 0.656. It was found that, in the design of turbines in the auxiliary power drive class, Reynolds number plays an important part in the selection of the design efficiency. Comparison with theoretical efficiencies based on a loss coefficient and velocity diagrams are presented. Close agreement was obtained between theory and experiment when the loss coefficient was adjusted for changes in Reynolds number to the -1/5 power.

    Application of Gas Analysis to Combustor Research (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: The performance of turbine-engine combustors usually is given in terms of operating limits and combustion efficiency. The latter property is determined most often by measuring the increase in enthalpy across the combustor through the use of thermocouples. This investigation was conducted to determine the ability of gas-analytical techniques to provide additional information about combustor performance. Gas samples were taken at the outlet and two upstream stations and their compositions determined. In addition to over-all combustion efficiency, estimates of local fuel-air ratios, local combustion efficiencies, and heat-release rates can be made. Conclusions can be drawn concerning the causes of combustion inefficiency and may permit corrective design changes to be made more intelligently. The purpose of this investigation was not to present data for a given combustor but rather to show the types and value of additional information that can be gained from gas-analytical data.

    Comparison of Measured Flapwise Structural Bending Moments on a Teetering Rotor Blade With Results Calculated From the Measured Pressure Distribution (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: Flapwise bending moments were calculated for a teetering rotor blade using a reasonably rapid theoretical method in which airloads obtained from wind-tunnel tests were employed. The calculated moments agreed reasonably well with those measured with strain gages under the same test conditions. The range of the tests included one hovering and two forward-flight conditions. The rotor speed for the test was very near blade resonance, and difficult-to-calculate resonance effects apparently were responsible for the largest differences between the calculated and measured harmonic components of blade bending moments. These differences, moreover, were largely nullified when the harmonic components were combined to give a comparison of the calculated and measured blade total- moment time histories. The degree of agreement shown is therefore considered adequate to warrant the use of the theoretical method in establishing and applying methods of prediction of rotor-blade fatigue loads. At the same time, the validity of the experimental methods of obtaining both airload and blade stress measurement is also indicated to be adequate for use in establishing improved methods for prediction of rotor-blade fatigue loads during the design stage. The blade stiffnesses and natural frequencies were measured and found to be in close agreement with calculated values; however, for a condition of blade resonance the use of the experimental stiffness values resulted in better agreement between calculated and measured blade stresses.

    Effect of Six Missile-Bay Baffle Configurations and a Rocket End Plate on Ejection Releases of an MB-1 Rocket from a 0.05 Scale Model of the Convair F-106A Airplane (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: As a continuation of an investigation of the release characteristics of an MB-1 rocket carried internally by the Convair F-106A airplane, six missile-bay baffle configurations and a rocket end plate have been investigated in the 27- by 27-inch preflight jet of the NASA Wallops Station. The MB-1 rocket used had retractable fins and was ejected from a missile bay modified by the addition of six different baffle configurations. For some tests a rocket end plate was added to the model. Dynamically scaled models (0.04956 scale) were tested at a simulated altitude of 22,450 feet and Mach numbers of 0.86, 1.59, and 1.98, and at a simulated altitude of 29,450 feet and a Mach number of 1.98. The results of this investigation indicate that the missile-bay baffle configurations and the rocket end plate may be used to reduce the positive pitch amplitude of the MB-1 rocket after release. The initial negative pitching velocity applied to the MB-1 rocket might then be reduced in order to maintain a near-level-flight attitude after release. As the fuselage angle of attack is increased, the negative pitch amplitude of the rocket is decreased.

    Approach and Landing Investigation at Lift-Drag Ratios of 2 to 4 Utilizing a Straight-Wing Fighter Airplane (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: A series of landings was performed with a straight-wing airplane to evaluate the effect of low lift-drag ratios on approach and landing characteristics. Landings with a peak lift-drag ratio as low as 3 were performed by altering the airplane configuration (extending speed brakes, flaps, and gear and reducing throttle setting). As lift-drag ratio was reduced, it was necessary either to make the landing pattern tighter or to increase initial altitude, or both. At the lowest lift-drag ratio the pilots believed a 270 deg overhead pattern was advisable because of the greater ease afforded in visually positioning the airplane. The values of the pertinent flare parameters increased with the reduction of lift-drag ratio. These parameters included time required for final flare; speed change during final flare; and altitude, glide slope, indicated airspeed, and vertical velocity at initiation of final flare. The pilots believed that the tolerable limit was reached with this airplane in the present configuration, and that if, because of a further reduction in lift-drag ratio, more severe approaches than those experienced in this program were attempted, additional aids would be required to determine the flare-initiation point.

    Exploratory Investigation of Aerodynamic Flameholders for Afterburner Application (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: An investigation was conducted to determine the flameholding capabilities of aerodynamic jets at afterburner operating conditions. Stability data for a number of aerodynamic flameholders were obtained in a 5- by 5-inch test section at inlet-air reference velocities up to 600 feet per second, an inlet-air temperature of 1250 F, and a combustor-inlet pressure of 15 inches of mercury absolute. Combustion efficiency and stability data of the more promising combinations were then obtained in a 10- by 12-inch test section at the same test conditions. Both air and stoichiometric mixtures of fuel and air were used in the jets; mixture flow rates were approximately 1 percent by weight of the total air-flow rate. Injection pressures were limited to values that might be available from compressor-bleed air. At a reference velocity of 600 feet per second, aerodynamic flame-holders alone were unable to maintain a stable flame at injection pressures up to 70 pounds per square inches large reductions in velocity were required to achieve flame stabilization. When the aerodynamic jets were used in combination with a V-gutter flameholder with approximately a 30 percent blocked area, flame stabilization was attained at a velocity of 600 feet per second; however, the combustion efficiencies of the various combinations were no greater than that obtained with the V-gutter alone.

    Comparison of Calculated and Experimental Total-Pressure Loss and Airflow Distribution in Tubular Turbojet Combustors with Tapered Liners (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: Incompressible-flow calculations were performed to determine the effects of combustor geometric and operating variables on pressure loss and airflow distribution in a tubular combustor with a tapered liner. The calculations include the effects of momentum transfer between annulus and liner gas streams, annulus wall friction, heat release, and discharge coefficients of liner air-entry holes. Generalized curves are presented which show the effects of liner-wall inclination, liner open hole area, and temperature rise across the combustor on pressure loss and airflow distribution for a representative parabolic liner hole distribution. A comparison of the experimental data from 12 tapered liners with the theoretical calculations indicates that reasonable design estimates can be made from the generalized curves. The calculated pressure losses of the tapered liners are compared with those previously reported for tubular liners.

    Performance of Typical Rear-Stage Axial-Flow Compressor Rotor Blade Row at Three Different Blade Setting Angles (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: A comparison of the performance of a single-stage rotor run at three different blade setting angles is presented. The rotor was of a design typical for a last stage of a multistage compressor. At each setting angle, the rotor blade row was operated from 53 to 100 percent of equivalent maximum speed (850 ft/sec tip speed) at constant inlet pressure. Hot-wire anemometry was used to observe rotating-stall and surge patterns in time unsteady flow. Results indicated that an increase in peak pressure ratio and an increase in maximum equivalent weight flow were obtained at each speed investigated when the blade setting angle was decreased. An increase in peak efficiency was achieved with decrease in blade setting angle for part of the range of speeds investigated. However, the peak efficiencies for the three blade setting angles were approximately the same at the maximum speed investigated. The flow ranges for all three configurations were about the same at minimum speed and decreased at almost the same rate when the rotative speed was increased through part of the range of speeds investigated. At maximum speed, the flow range for the smallest setting angle was considerably less than the flow range for the other two configurations. A decrease in efficiency and flow range for the smallest blade setting angle at maximum speed can be attributed primarily to a Mach number effect. In addition, because of the difference in projected axial chord lengths at the casing wall, some effect on performance could be expected from the change in three-dimensional flow occurring at the tip. Rotating-stall characteristics for the two smaller blade setting angles were essentially the same. Only surge could be detected for the largest blade setting angle in the unstable-flow region of operation.

    Flight Investigation of Effects of Transition, Landing Approaches, Partial-Power Vertical Descents, and Droop-Stop Pounding on the Bending and Torsional Moments Encountered by a Helicopter Rotor Blade (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: Flight tests have been conducted with a single-rotor helicopter, one blade of which was equipped at 14 percent and 40 percent of the blade radius with strain gages calibrated to measure moments rather than stresses, to determine the effects of transition, landing approaches, and partial-power vertical descents on the rotor-blade bending and torsional moments. In addition, ground tests were conducted to determine the effects of static droop-stop pounding on the rotor-blade moments. The results indicate that partial-power vertical descents and landing approaches produce rotor-blade moments that are higher than the moments encountered in any other flight condition investigated to date with this equipment. Decelerating through the transition region in level flight was found to result in higher vibratory moments than accelerating through this region. Deliberately induced static droop-stop pounding produced flapwise bending moments at the 14-percent-radius station which were as high as the moments experienced in landing approaches and partial-power vertical descents.

    Some Static Oscillatory and Free Body Tests of Blunt Bodies at Low Subsonic Speeds (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: Some blunt-body shapes considered suitable for entry into the earth's atmosphere were tested by both static and oscillatory methods in the Langley stability tunnel. In addition, free-fall tests of some similar models were made in the Langley 20-foot free-spinning tunnel. The results of the tests show that increasing the flare of the body shape increased the dynamic stability and that for flat-faced shapes increasing the corner radius increased the stability. The test data from the Langley stability tunnel were used to compute the damping factor for the models tested in the langley 20-foot free-spinning tunnel. For these cases in which the damping factor was low, -1/2 or less, the stability was critical and sensitive to disturbance. When the damping factor was about -2, damping was generally obtained.

    Investigation of the Effects of Low Reynolds Number Operation on the Performance of a Single-Stage Turbine with a Downstream Stator (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: High-altitude turbojet performance is adversely affected by the effects of low air density. This performance loss is evaluated as a Reynolds number effect, which represents the increased significance of high fluid viscous forces in relation to dynamic fluid forces as the Reynolds number is decreased. An analytical and experimental investigation of the effects of low Reynolds number operation on a single-stage, high-work-output turbine with a downstream stator was carried out at Reynolds numbers of 182,500, 39,600, and 23,000, based on average rotor-design flow conditions. At low Reynolds numbers and turbulent flow conditions, increased viscous losses caused decreased effective flow area, and thus decreased weight flow, torque, and over-all efficiency at a given equivalent speed and pressure ratio. Decreasing the Reynolds number from 182,500 to 23,000 at design equivalent speed resulted in a 5.00-point loss in peak over-all turbine efficiency for both theory and experiment. The choking equivalent weight flow decreased 2.30 percent for these conditions. Limiting loading work output was reached at design equivalent speed for all three Reynolds numbers. The value of limiting loading work output at design speed decreased 4.00 percent as Reynolds number was decreased from 182,500 to 23,000. A theoretical performance-prediction method using basic boundary-layer relations gave good agreement with experimental results over most of the performance range at a given Reynolds number if the experimental and analytical design operating conditions were carefully matched at the highest Reynolds number with regard to design performance parameters. High viscous losses in the inlet stator and rotor prevented the attainment of design equivalent work output at the lowest Reynolds number of 23,000.

    A Limited Study of a Hypothetical Winged Anti-ICBM Point-Defense Missile (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: A preliminary investigation was conducted to determine whether a warhead stage of an antimissile missile could be placed within an arbitrary 2-nautical-mile-radius maneuver cylinder around an intercontinental-ballistic-missile (ICBM) flight path above an altitude of 140,000 feet, a horizontal range of 40 nautical miles, at a flight-path angle of approximately 20 deg, and within 50 seconds after take-off using only aerodynamic forces to turn the antimissile missile. The preliminary investigation indicated that an antimissile missile using aerodynamic forces for turning was capable of intercepting the ICBM for the stated conditions of this study although the turning must be completed below an altitude of approximately 70,000 feet to insure that the antimissile missile will be at the desired flight-path angle. Trim lift coefficients on the order of 2 to 3 and a maximum normal-acceleration force of from 25g to 35g were necessary to place the warhead stage in intercept position. The preliminary investigation indicated that for the two boosters investigated the booster having a burning time of 10 seconds gave greater range up the ICBM flight path than did the booster having a burning time of 15 seconds for the same trim lift coefficient and required the least trim lift coefficient for the same range.

    Roll Utilization of an F-100A Airplane During Service Operational Flying (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: As a means of evaluating the roll utilization of a fighter airplane capable of supersonic speeds, an instrumented North American F-100A fighter airplane was flown by U.S. Air Force pilots at Nellis Air Force Base, NV, during 20 hours of service operational flying. Mach numbers up to 1.22 and altitudes up to 50,000 feet were realized in this investigation. Results of the study showed that except for high g barrel rolls performed as evasive maneuvers and rolls performed in acrobatic flying, rolling was utilized primarily as a means of changing heading. Acrobatic and air combat maneuvering produced the largest bank angles (1,200 deg), roll velocities (3.3 radians/sec), rolling accelerations (8 radians/sq sec) and sideslip angles (10.8 deg). Full aileron deflections were utilized on numerous occasions. Although high rolling velocities and accelerations also were experienced during several air-to-air gunnery missions, generally, air-to-air gunnery and air-to-ground gunnery and bombing required only two-thirds of maximum aileron deflection. The air-to-air gunnery and air combat maneuvers initiated from supersonic speeds utilized up to two-thirds aileron deflection and bank angles of less than 18 deg and resulted in rolling velocities and accelerations of 2 radians per second and 4.6 radians/sq sec, respectively. Rolling maneuvers were often initiated from high levels of normal acceleration, but from levels of negative normal acceleration only once.

    Flight Measurements of the Effect of a Controllable Thrust Reverser on the Flight Characteristics of a Single-Engine Jet Airplane (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: A flight investigation was undertaken to determine the effect of a fully controllable thrust reverser on the flight characteristics of a single-engine jet airplane. Tests were made using a cylindrical target-type reverser actuated by a hydraulic cylinder through a "beep-type" cockpit control mounted at the base of the throttle. The thrust reverser was evaluated as an in-flight decelerating device, as a flight path control and airspeed control in landing approach, and as a braking device during the ground roll. Full deflection of the reverser for one reverser configuration resulted in a reverse thrust ratio of as much as 85 percent, which at maximum engine power corresponded to a reversed thrust of 5100 pounds. Use of the reverser in landing approach made possible a wide selection of approach angles, a large reduction in approach speed at steep approach angles, improved control of flight path angle, and more accuracy in hitting a given touchdown point. The use of the reverser as a speed brake at lower airspeeds was compromised by a longitudinal trim change. At the lower airspeeds and higher engine powers there was insufficient elevator power to overcome the nose-down trim change at full reverser deflection.

    Engine Operating Conditions that Cause Thermal-Fatigue Cracks in Turbojet-Engine Buckets (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: Five engine tests were conducted to definitely establish the failure mechanism of leading-edge cracking and to determine which conditions of engine operation cause the failures. Five groups of S-616 and M-252 buckets from master lots were run consecutively in the same J47-25 engine. The tests included a steady-state run at full-power conditions, rapid cycling between idle and rated speed, and three different start-stop tests. The first start-stop test consisted of cycles of start and stop with 5 minutes of idle speed before each stop; the second included cycles of start and stop but with 15 minutes of rated speed before each stop; the third consisted of cycles of gradual starts and normal stops with 5 minutes at idle speed before each stop. The test results demonstrated that the primary cause of leading-edge cracking was thermal fatigue produced by repeated engine starts. The leading edge of the bucket experiences plastic flow in compression during starts and consequently is subjected to a tensile stress when the remainder of the bucket becomes heated and expands. Crack initiation was accelerated when rated-speed operation was added to each normal start-stop cycle. This acceleration of crack formation was attributed to localized creep damage and perhaps to embrittlement resulting from overaging. It was demonstrated that leading-edge cracking can be prevented simply by starting the engine gradually.

    Experimental Investigation of a 0.35 Hub-Tip Radius Ratio Transonic Axial Flow Rotor Designed for 40 Pounds per Second per Square Foot with a Design Tip Diffusion Factor of 0.20 (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: In order to determine the effect of a low design diffusion factor on the performance of a transonic axial-flow compressor rotor, a high-specific-flow rotor with a 0.35 hub-tip radius ratio was designed, fabricated and tested. This rotor used a design tip diffusion factor of 0.20 with a design corrected specific weight flow of 40 pounds per second per square foot of frontal area, a total-pressure ratio of 1.27, and an adiabatic efficiency of 0.96. The design, rotor performance, and blade element performance are presented with a discussion on rotor shock losses and a comparison with a similarly designed rotor with a tip diffusion factor of 0.35. At the design corrected tip speed of 1100 feet per second, a peak rotor adiabatic efficiency of 0.88 was attained at a corrected specific weight flow of 39 pounds per second per square foot of frontal area with a mass-averaged total-pressure ratio of 1.27. The blade element tip diffusion factor was 0.281, which is 0.08 higher than the design value of 0.20. Peak efficiencies of 0.95, 0.91, 0.89, and 0.85 were obtained at 70, 80, 90, and 110 percent of design speed, respectively. Comparison of the performance of the rotor reported herein and a similarly designed rotor with increased blade loading indicates that higher blade loading results in a more desirable rotor because of a higher pressure ratio and equivalent efficiency. Computed values of shock losses at the rotor tip section indicate that the losses at peak efficiency are primarily a function of shock losses since the profile losses are only a small percentage of the total loss.

    Measurements Obtained During the First Landing of the North American X-15 Research Airplane (1959)
    In:  CASI
    Details
    Publication Date: 2019-08-16
    Description: The first landing of the X-15 airplane was made at 8:43 a.m., June 8, 1959, on the hard surface of Rogers Dry Lake. One purpose of the first-glide flight was to evaluate the effectiveness of the landing-gear system. Some results are presented of the landing-approach characteristics, the impact period, and the runout phase of the landing maneuver. The results indicate that the touchdown was accomplished at a vertical velocity of 2.0 feet per second for the main gear and 13.5 feet per second for the nose gear. These vertical velocities were within the values of sinking speeds established by structural design limitations. However, permanent structural deformation occurred in the main-landing-gear system as a result of the landing, and a reevaluation of the gear is being made by the manufacturer. The landing occurred at a true ground speed of 158 knots for main-gear touchdown at an angle of attack of 8.50. The incremental acceleration at the main gear was 2.7g and 7.39 at the nose gear as a result of the landing. The incremental acceleration at the center of gravity of the airplane was 0.6g for the main-gear impact and 2.4g for the nose-gear impact. The incremental acceleration at the main gear as a result of the nose-gear impact was 4.8g. The extreme rearward location of the main-gear skids appears to offer satisfactory directional stability characteristics during the run- out phase of the landing. No evidence of nosewheel shimmy was indicated during the impact and runout phase of the landing despite the absence of a shimmy damper on the nose gear. The maximum amount of skid wear as a result of the landing was on the order of 0.005 inch. No appreciable amount of tire wear was indicated for the dual, corotating nosewheels.

    Description / Table of Contents: Latest Developments in Antirust PaintingFor constructions made of steel a durable protection against rust can only be achieved if all factors conditioning the corrosive effects, especially the environmental influences like rain, dew, the dew point, temperature and agressiveness of the atmosphere, are considered. Their effects on the problem of priming and preliminary treatments of the surface (removal of scale and rust), on the efficiency of rust removers as well as on the protective value of wash primers are discussed. This is followed by information on the composition of protective paints, pigments and binders for priming and the composition of top coats; the specific aptitude of pigments, fillers and binders as well as on protective top paints.
    Notes: Ein dauerhafter Rostschutz von Stahlbauwerken setzt die Kenntnis aller sich auswirkenden Faktoren, insbesondere der Umwelteinflüsse wie Regeneinwirkung, Taubildung, Taupunkt, Temperatur und Aggressivität der Atmosphäre voraus. Ihre Auswirkung auf die Frage der Werksgrundierung, insbesondere der Untergrundvorbereitung (Entzunderung, Entrostung, Eignung) von Rostumwandlern und Schutzwert von Wash-Primern wird besprochen. Es folgen grundsätzliche Angaben über den Aufbau der Schutzanstrichmittel, Pigmente und Bindemittel für Grundierungen, über verschiedenartige Grundanstriche, über die Zusammensetzung der Deckanstriche, der spezifischen Eignung der Pigmente, Füllstoffe und Bindemittel, und über Rostschutz-Deckfarben.

    Description / Table of Contents: The Influence of Protective Colloids upon the Corrosion of BrassSome investigations showed that the corrosion of brass by acid plant substances is much lower than that caused by the corresponding vegetable acids of the same pH-value. The reason is obviously the presence of colloids in the plant matter. The article presents the results of investigations on the effects of protective colloids like pulvis acacia, e.g. albumin, agar, dextrine and potato starch upon the corrosion of brass in citric acid, hydrochloric acid and sulfuric acid. The data are represented in chart form. The protective effects of the various colloids differ very much according to the combination of colloid and acid. While an essential decrease of corrosion took place in citric acid solutions which is explained by an adsorption of colloid on the metal surface and the formation of a protective cover, the rate of corrosion was increased if hydrochloric acid was used even at constant concentration of colloids. Here dezincification took place which means that the more basic metal suffered a more intensive corrosive attack. The authors believe that protection in hydrochloric solutions could be achieved if a higher concentration of the colloid were used.
    Notes: Bei Forschungsarbeiten war gefunden worden, daß die Korrosion von Messing durch säuernde pflanzliche Substanzen geringer war als die durch die entsprechenden Fruchtsäuren mit gleichem pH verursachte Korrosion. Der Grund der Herabsetzung war offenbar der Kolloidgehalt der Pflanzen und in der vorliegenden Arbeit werden die Resultate von Untersuchungen über die Einwirkung derartiger Schutzkolloide wie Pulvis Acacia, Ei-Albumin, Agar, Dextrin und Kartoffelstärke auf die Korrosion von Messing in Zitronensäure, Salzsäure und Schwefelsäure vorgelegt. Das Material wurde in Tabellen zusammengestellt. Es zeigte sich, daß die Schutzwirkung der verschiedenen Kolloide sehr unterschiedlich war, sowohl in Bezug auf die Kolloide selbst als auch auf die angewandten Säuren. Während sich bei Zitronensäure deutliche Schutzwirkung durch Herabsetzung der Korrosion einstellte, die durch Adsorption des Kolloids an das Metall und Bildung eines Schutzfilms erklärt wird, wurde bei Salzsäure die Korrosion erhöht, wenn die gleichen Kolloidkonzentrationen angewendet wurden und es trat “Entzinkung” ein, d. h., das basische Metal wurde stärker angegriffen. Die Verfasser sind der Meinung, daß bei Verwendung höherer Kolloidkonzentrationen auch bei Salzsäure Schutzwirkung eintreten würde.

    Description / Table of Contents: On the Electro-Deposition of Titanium from Aqueous Solutions of Potassium-Titanium-FluorideAs discerned from current density-voltage curves titanium can be deposited from aqueous solutions of potassium titanium fluoride. The deposition of the metal takes place by the formation of TiO++ ions and their reduction by nascent hydrogen. The cathode must consist of metals with high overvoltage. On aluminium cathodes deposition of titanium and passivation by aluminium and titanium hydroxides take place simultaneously.The effects are in agreement with the law of the formation of surface covers by Müller Machu. The current yields are very low. Though they would not exceed 30 pct. the current yields of this method are higher than ever before when other titaniums salts are used.On zinc cathodes there is no passivation. So the percentage of the metallic titanium in the deposition is higher than on aluminum cathodes. Micro-photographs demonstrate the influences of additives like gelatin, thiourea etc. which suppress the formation of hydroxides and oxides in the deposition. The formation thick deposits of titanium which are free from oxides is still meeting difficulties.
    Notes: Titan läßt sich, wie anhand von Strom-Spannungskurven gezeigt wird, aus dem Kaliumtitanfluorid in wäßriger Lösung abscheiden. Dabei erfolgt die Metallabscheidung auf dem Umweg über die Bildung von Ti2+-Ionen und durch Reduktion durch naszierenden Wasserstoff. Als Kathodenmaterial sind nur Metalle mit hoher Überspannung geeignet. An Aluminiumkathoden erfolgt während der Titanabscheidung auch eine Passivierung durch Aluminium- und Titanhydroxyd, wobei das Flächenbedeckungsgesetz von Müller-Machu erfüllt ist. Die Stromausbeuten sind nur gering, sie übersteigen 30% nicht, sind aber weit größer als dies mit anderen Titansalzlösungen bisher möglich war.An Zinkkathoden fehlt die Passivierung, daher ist der Anteil an metallischem Titan im Niederschlag größer als an Aluminium. Anhand von Mikrophotos wird der Einfluß von Zusätzen wie Gelatine, Thiobarnstoff u. dergl. aufgezeigt, welche die Bildung von Hydroxyd und Oxyd im Niederschlag unterdrücken. Die Herstellung dickerer Titanniederschläge, frei von Oxyden, bereitet noch Schwierigkeiten.

    Description / Table of Contents: High Temperature Corrosion in Petrol Refining by Sulfur CompoundsAt temperatures above 260°C only stainless, highly alloyed steels resist the attack of the most corrosive agent in petrol refining which is hydrogen sulfide. For high temperature corrosion by hydrogen sulfide, the influences of the duration of wear, the concentration of the hydrogen sulfide, the pressure, the properties of the refined petrol and the quality of the steel are of essential importance besides of the effects of temperature. The author reports on last years investigations in BP-research station on the corrosion of stainless steels by hydrogen sulfide at high temperatures. The corrosion of the surface, the inter-crystalline corrosion and the stress corrosion of steels are discussed in detail.
    Notes: Dem Angriff des wesentlichsten korrosiven Agens in Erdölraffinerien, dem Schwefelwasserstoff, bei hohen Temperaturen (über 260°C) widerstehen praktisch ausschließlich rostfreie, hochlegierte Stähle. Bei der Hochtemperatur-Korrosion durch Schwefelwasserstoff sind neben der Temperatur auch Beanspruchungsdauer, Schwefelwasserstoff konzentration, Druck, Beschaffenheit des zu raffinierenden Öles und die Stahlqualität von Einfluß. Verfasser berichtet über die in den letzten Jahren in der BP-Research Station durchgeführten Untersuchungen über die Korrosion von rostfreien Stählen durch Schwefelwasserstoff bei hohen Temperaturen, wobei allgemeine Oberflächen-korrosion, interkristalline Korrosion und Spannungskorrosion der Stähle eingebend behandelt werden.

    Description / Table of Contents: New Investigations into Hydrogen Adsorption and Dissolved IronThe solution processes of iron in n HCl were investigated and a correlation was found between the quantity of hydrogen absorbed in the iron and the rate at which the metal dissolved. A dynamical saturation equilibrium was established in the interior of the metal. From this the significance of partial reactions can be derived and the action of inhibitors explained.
    Notes: Es wurden die Auflösungsvorgänge von Eisen in In-HCL untersucht und ein Zusammenhang zwischen der Menge des vom Eisen aufgenommenen Wasserstoffs und der Auflösungsgeschwindigkeit des Metalls gefunden. Es stellt sich dabei ein dynamisches Sättigungsgleichgewicht im Innern des Metalls ein. Daraus läßt sich die Bedeutung der Teil-Reaktionen ableiten und das Eingreifen von Inhibitoren erklären.

    Description / Table of Contents: Investigations of Pitting on Highly Alloyed Austenitic Chrome Nickel Steels and Ferritic Chrome Steels in Aqueous Solutions Containing HalidesTbe application of stainless steels in aqueous solutions containing halides is limited.The authors show that it is not the corrosion potential, determined by means of the generally applied test in a 10 pct. FeCl3-solution, but the slope of the potential vs. current density as a electrochemical data which indicates the sensitivity to pitting.The K3[Fe(CN)6]-test has proved to be a good quick method. By means of this method pitting is indicated as a active passive reaction.Pitting occurs only at potentials within a certain range which can be determined from a current density-voltage curve.In a 5 pct. sulfuric acid containing air, at room temperature the uniform transpassive dissolution of steel takes place only. In sulfuric acid solutions containing chlorides steel is corroded uniformly in its active state or by pitting but not transpassively. An addition of nitrate to such a solution inhibits pitting but increases the transpassive corrosion.
    Notes: Die Einsatzmöglichkeit der chemisch beständigen Stähle in halogenidhaltigen, wäßrigen Medien wird durch die Erscheinung der Lochfraßkorrosion eingeschränkt.Es wird gezeigt, daß bei der allgemein üblichen Prüfung in einer 10%igen FeCl3-Lösung für die Lochfraßanfälligkeit nicht das Korrosionspotential, sondern der Polarisationswiderstand als elektrochemische Meßgröße kennzeichnend ist.Als praktisches Schnellprüfverfahren hat sich der K3[Fe(CN)6]-Test bewährt. Mit Hilfe dieser chemischen Indikation wird der Lochfraß-Mechanismus als Aktiv-Passiv-Reaktion bewiesen. Das Auftreten der Lochfraßkorrosion ist an einen gewissen Potentialbereich gebunden, der durch Messung der Stromdichte-Potential-Kurve bestimmt werden kann.In reiner lufthaltiger 5%iger Schwefelsäure ist bei Raumtemperatur nur die gleichmäßig transpassive Stahlauflösung möglich. In chloridhaltiger Schwefelsäure kann der Stahl gleichmäßig aktiv oder durch Lochfraß, dagegen nicht transpassive korrodieren. Durch einen Nitratzusatz zur chloridhaltigen Schwefelsäure wird die Lochfraßkorrosion zugunsten der transpassiven Korrosion inhibitiert.

    Description / Table of Contents: On the Photo-Chemistry of Metallic Copper and its Influence on the Velocity of the Dissolution of Copper as ElectrodeBy etching copper with a mixture of nitric and hydrochloric acid, a sensitive layer is formed which is blackened according to the duration of the exposion to light. An exposion by means of a 6,7 V-incandescent lamp at a distance of 10 cm from the copper surface generates a spot of 1,75 cm2 surface. Three discontinuities occur in certain intervals. The intensity of the reflexion was measured by means of a photoelectric cell and a mirror-galvanometer. Increase of temperature causes a decrease of the velocity of blackening the sensitive layer. Observing the influence of light upon the velocity of the dissolution of copper we obtained a typical dependance of the velocity of corrosion on the photochemical reaction on the copper surface.
    Notes: Durch Ätzung von Kupfer mit einem HNO3-HCl-Gemisch entsteht eine photoaktive Kupferschicht, die nach Belichtung eine zeitlich abhängige Schwärzung aufweist. Bei der Belichtung mit einer 6,7 V-Glühlampe in einem Abstand von 10 cm wird auf der Kupferoberfläche ein Lichtfleck von etwa 1,75 cm2 gebildet. In bestimmten Zeitintervallen treten sodann drei Diskontinuitäten auf. Die Intensität der Reflexion wurde mit Photozelle und Spiegelgalvanometer registriert. Die Erhöhung der Temperatur führt zur Verminderung der Schwärzungsgeschwindigkeit der photoaktiven Schicht.Die Beobachtungen über den Einfluß des Lichtes auf die Auflösungsgeschwindigkeit des Kupfers in Elektrolyten ergaben eine typische Abhängigkeit der Korrosionsgeschwindigkeit von der an der Kupfer-Oberfläche stattgefundenen Reaktion.

    Description / Table of Contents: Investigations on the Corrosion Behavior of Aluminum and Aluminum Alloys upon Organic and Inorganic BasesThe article presents a comparison of the corrosive effects of organic and inorganic bases upon aluminium materials by means corrosion tests carried out at a temperature of 20°C for 73hrs. The aggressivity of the bases investigated decreases in the order of sodium hydroxide, methylamine, ethylamine, n-butylamine, ammonia, triethanolamine, sodium carbonate, calcium hydroxide, hydrazine. The sensitivity to corrosion of the materials decrease in the order of pure aluminium A1 99,3, purest aluminium Raffinal raf W(more than 99,99% Al) anticorodal Ac B, Avional Av-23 V, Perunal Pu V and Peraluman Pe-30 W. For every mixture of a base and water, there is a critical concentration at which the intensity of the attack reacher its maximum. High concentrated bases cause but low corrosion and anhydrous bases are fairly inactive. There is no destinct relationship between the corrosion behavior of the bases and their pH-values resp. their electric conductivity.
    Notes: In der vorliegenden Abhandlung wird auf Grund von bei 20°C durchgeführten 73stündigen Korrosionsversuchen mit verschiedenen Aluminiumwerkstoffen die aluminiumangreifende Wirkung organischer Basen mit der anorganischer verglichen. Die Aggressivität der untersuchten Basen nimmt in der anorganischer verglichen. Die Aggressivität der untersuchten Basen nimmt in der Reihenfolge Natriumhydroxyd, Methylamin, Aethylamin, n-Butylamin, Ammoniak, Triäthanolamin, Natriumcarbonat, Calciumhydroxyd, Hydrazin ab. Die Korrosionsfälligkeit einzelner Werkstoffe vermindert sich entsprechend der Reihe Reinaluminium Al 99,3, Reinstaluminium Raffinal Raf W (über 99,99% Al), Anticorodal Ac B, Avional Av-23 V, Perunal Pu V und Peraluman Pe-30 W. Bei jedem Gemisch Base/Wasser besteht eine kritische Konzentration, bei welcher die Intensität des Angriffs auf Aluminium ein Maximum erreicht. Sehr konzentrierte Basen wirken nur ganz schwach, wasserfreie Basen kaum aluminiumangreifend. Zwischen den Korrosionseigenschaften der einzelnen Basen und ihrem pH-Wert bzw. ihrer elektrischen Leitfähigkeit bestehen keine eindeutigen Zusammenhänge.

    Description / Table of Contents: A theory on the complementing process in phosphating baths(Formation rate of secondary cover layers on metals)Secondary cover layers are deposited on metals from saturated solutions if the equilibrium of the solution is disturbed by corrosion on the metal surface. The rate of corrosion and the rate at which the layer is formed are compared, using the phosphate treatment of iron as an example. With this process, the quotient of the HṠ consumed and the iron dissolved is governed by the stoichiometry of the oxidation reaction concerned. The quotients of the HṠ consumed and the quantity of the zinc phosphate deposit can be calculated if all reactions are diffusion controlled. It is thus assumed that the crystal nuclei are formed rapidly, and that equilibria between zinc and phosphoric acid in the solution remain adjusted upto the metal surface. This theory is confirmed experimentally. It serves to indicate and to determine the composition of complementry solution by means of which the baths can be kept stable.
    Notes: Sekundäre Deckschichten scheiden sich aus gesättigten Lösungen auf Metallen ab, wenn an der Metalloberfläche das Lösungsgleichgewicht durch Korrosion gestört wird. Die Geschwindigkeiten von Korrosion und Abscheidung werden am Beispiel der Phosphatierung von Eisen verglichen. Dabei ist der Quotient aus verbrauchtem H und gelöstem Eisen durch die Stöchiometrie der jeweiligen Oxydationsreaktion bedingt. Der Quotient aus verbrauchten H und Menge des Zinkphosphatniederschlags ist zu berechnen, wenn alle Reaktionen transportbestimmt sind. Es wird also angenommen, daß die Gleichgewichte zwischen Zink und Phosphorsäure in der Lösung bis hin zur Metalloberfläche eingestellt bleiben. Die Theorie wird experimentell bestätigt. Sie dient dazu, um Bäder mit optimalen Eigenschaften anzugeben. Ferner erlaubt sie, die Zusammensetzung von Ergänzungslösungen zu berechnen, mit denen die Bäder stationär gehalten werden können.

    Description / Table of Contents: New investigations on vapor phase inhibitorsIn connection to basic investigations on the protection against corrosion of metal surfaces by VPI, the authors tested the effects of some VPI upon the stability in storage of gray iron in air of 100 pct. relative humidity.Interpreting the results of different tests the authors accentuate the necessity of minimum quantities of VPI to achieve a protective effect.Tests with VPI impregnated wrapping paper in touch with the metal surface show that this method may be applied to cast iron also. Furthermore the effects of some VPI upon different metal surfaces at alternating temperatures were determined. The specimens, arranged in varying positions and different distances from the inhabitors, were subjected to transport conditions. The importance of these factors for the protective value of VPI is turned out.
    Notes: Im Anschluß an ihre Grundlagen-Forschungen auf dem Gebiete des Korrosionsschutzes metallischer Oberflächen durch Dampfphasen-Inhibitoren untersuchten die Verfasser die Wirkung einiger V. P. I. auf die Lagerbeständigkeit von Graugußteilen in Luft von 100% relativer Feuchtigkeit.Bei Auswertung der bei verschiedenen Untersuchungen erhaltenen Daten wird darauf hingewiesen, daß zum Schutz von Gußstücken ausreichende V. P. I.-Mengen vorhanden sein müssen.Bei Versuchen, bei denen die auf das Verpackungspapier aufgetragene V. P. I. mit den Metalloberflächen in Berührung standen, ergab sich, daß diese Schutzart auch bei Gußeisen anwendbar ist. Weiter wurde die Wirkung einiger V. P. I. gegenüber verschiedenartigen Metalloberflächen bei wechselnden Temperaturen quantitative ermittelt. Die der Einwirkung der V. P. I. ausgesetzten Prüflinge wurden in verschiedenen Lagen und Entfernungen vom Inhibitor exportiert; die Bedeutung dieser Faktoren für den Schutzwert der V. P. I. wurde deutlich herausgestellt.

    Description / Table of Contents: Influence of structural factors on the corrosion of stainleaa steelDepending on the influence of their surroundings, austenitic stainless steels show great differences in their corrosion behaviour; they may be corrosion-proof, or passive in corrosive oxidants, or they may, in acid solutions, corrode as rapidly as iron and steel.This behaviour is directly connected with the phenomenon of passivity, or with the influence exerted, by virtue of its structure, by the passive state of the surface of stainless on the occurrence, intensity and type of corrosion. The author has investigated this effect of the surface structure in numerous tests, varying the composition and pre-treatment of the steels (machining, heat treatment, tempering, sensitivisation), the exposure times and oxidants (using boiling nitric acid), examining the influence of the grain size on intergranular corrosion, and determining the effect of clod drawing on the corrosion resistance of stainless steels. The article contains a detailed report about these tests, and the results are illustrated by 22 reproductions of microphotographs and of pictures obtained by the electron microscope.
    Notes: Austenitische rostfreie Stähle weisen stark unterschiedliches Korrosionsverhalten auf, je nachdem, welchen umgebenden Einflüssen sie ausgesetzt werden, sie können korrosionsfest oder passiv in korrodierenden Oxydationsmitteln sein oder können in sauren Lösungen ebenso schnell korrodieren wie Eisen und Stahl.Dieses Verhalten hängt direkt mit dem Phänomen der Passivität zusammen bzw. der Wirkung, die der passive Zustand der Oberfläche der rostfreien Stähle seiner Struktur nach auf das Auftreten, den Grad und die Art der Korrosion ausübt. Der Verfasser hat diese Wirkung der Oberflächenstruktur in zahlreichen Versuchen untersucht, er hat Zusammensetzung und Vorbehandlung der Stähle verändert  -  durch Polieren, Warmbehandlung, Temperung, Sensibilisierung  - , die Exponierungszeiten und Oxydationsmittel verändert  -  durch Verwendung von kochender Salpetersäure, Chromsäure oder Salzsäure  -  und die Einwirkung der Korngröße auf die intergranulare Korrosion sowie den Effekt der Kaltverformung auf die Korrosionsfestigkeit der rostfreien Stähle untersucht. Er gibt im Artikel einen ausführlichen Bericht über alle diese Versuche und belegt die erhaltenen Resultate durch 22 Mikrophotographien und elektronenmikroskopischen Aufnahmen.
