On the Distribution of Stress in a Thin Plate Elastically Supported Along Two Edges at Loads Beyond the Stability Limit

Description: Note presenting the results of an investigation on the distribution of stress in a plate elastically supported along two edges and subjected to compressive loads in a direction parallel to the elastically supported edges. A theoretical calculation was carried out in which the influence of the elastic support was taken into account.

An Investigation of Aircraft Heaters 4: Measured and Predicted Performance of Longitudinally Finned Tubes

Description: Report presenting a study of two double tube, cylindrical, longitudinally finned heat exchangers in which hot exhaust gases pass through the annular space and ventilating air passes through the center tube in order to determine heat transfer and pressure drop performance.

An Investigation of Aircraft Heaters 3: Measured and Predicted Performance of Double Tube Heat Exchangers

Description: Report presenting a study of two double tube cylindrical heat exchangers, in which hot exhaust gases pass through the annular space and ventilating air passes through the center tube, to determine heat transfer performance and pressure drop. Tests were performed in order to establish a simple, accurate method of predicting the performance of the double tube heat exchanger, to compare the performance of the straight and dimpled tubes, and to determine the pressure drop across the units.

A Flight Investigation of the Stability of a Towed Body

Description: Report presenting flight tests to determine whether a towed body that was designed to meet certain specifications met the stability specification, which required that angular deviations in flight should be less than 1 degree. The requirement was met in flight in smooth air, but not in rough air, where the rolling motions were considerably larger.

Effect of Countersunk Depth on the Tightness of Two Types of Machine-Countersunk Rivet

Description: Bulletin presenting an investigation conducted to determine the effect of countersunk depth on the tightness of two types of machine-countersunk flush rivet. The specimens tested in the study were simple lap joints made by two different riveting methods. The results indicated that roundheaded rivets inserted from the back of the joint with the countersunk heads formed int he driving of the rivets produce tighter joints over a large range of depths than ordinary flush rivets.

Elevator Stick Forces in Spins as Computed From Wind-Tunnel Measurements

Description: "Data from wind-tunnel measurements of elevator hinge-moment coefficients at high angles of attack are utilized in estimating elevator stick forces in spins. The analysis indicates that elevator forces on several current airplanes will be so high that the pilot will be unable to push the stick to the neutral position. Large nose balances involve danger of the elevator locking in the full-up position" (p. 1).

Theoretical Distribution of Load Over a Swept-Back Wing

Description: Report presenting a calculation of the load over an elliptical wing with 30 degrees sweepback by a method, based on vortex theory, which takes account of the chordwise distributions of lifting area. The theory indicates a 14-percent loss in total lift due to the introduction of sweepback, with the greatest loss taking place at the center of the span.

Performance of two-stage turbosupercharger using mixed-flow impellers

Description: Report presenting an investigation of the performance of a two-stage turbosupercharger with mixed-flow impellers. Two complete superchargers were tested; both were the same except for modified vanes in the interstage passage and a slightly different first-stage diffuser shape. The modified supercharger performed slightly better than the original, but both showed good characteristics over a range of operating conditions.

Investigation of Diving Moments of a Pursuit Airplane in the Ames 16-Foot High Speed Wind Tunnel

Description: From Summary: "A pursuit type airplane encountered severe diving moments in high-speed dives which make recovery difficult. For the purpose of investigating these diving moments and finding means for their reduction, a 1/6 scale model of the airplane was tested in the 16-foot high-speed wind tunnel at Ames Aeronautical Laboratory. The test results indicate that up to a Mach number of at least 0.75, the limit of the tests, the dive-recovery difficulties can be alleviated and the longitudinal maneuverability improved by the substitution of a long symmetrical fuselage for the standard fuselage."

Tests of a Large Spherical Turret and a Modified Turret on a Typical Bomber Fuselage

Description: "The drags of two alternate turrets for a military airplane were investigated through a Mach number range of 0.22 to 0.70 at angles of attack of 3, 5, and 7 degrees in the 8-foot high-speed tunnel. Force and pressure measurements were made with the turrets mounted on a bomber model. The results show that a large spherical turret added about 10 percent to the fuselage drag" (p. 1).

The Compressible Potential Flow Past Elliptic Symmetrical Cylinders at Zero Angle of Attack and with No Circulation

Description: "For the tunnel corrections of compressible flows those profiles are of interest for which at least the second approximation of the Janzen-Rayleigh method can be applied in closed form. One such case is presented by certain elliptical symmetrical cylinders located in the center of a tunnel with fixed walls and whose maximum velocity, incompressible, is twice the velocity of flow. In the numerical solution the maximum velocity at the profile and the tunnel wall as well as the entry of sonic velocity is computed" (p. 1).

[Memorandums on the Subject of Turbulent Boundary Layers in Compressible Gas at High Speeds]

Description: "The Reynolds law of heat transfer from a wall to a turbulent stream is extended to the case of flow of a compressible gas at high speeds. The analysis is based on the modern theory of the turbulent boundary layer with laminar sublayer. The investigation is carried out for the case of a plate situated in a parallel stream. The results are obtained independently of the velocity distribution in the turbulent boundar layer" (p. 1).

Contribution to the Design of Plywood Shells

Description: "The writer sets out to prove by calculation and experiment that by extensive utilization of the skin to carry axial load (reduction of stringer spacing) the stringer sections can be made small enough to afford a substantial saving in structural weight. This saving ranges from 5 to about 40 percent" (p. 1).
