Correcting Engine Tests for Humidity

Description: Note presenting tests using a multicylinder engine to determine the effect that atmospheric humidity has on some phases of engine performance. Three test series with different types of fuel were carried out. The results indicate that failure to allow for the effect of differences in atmospheric humidity may introduce errors as great as would be occasioned by failure to allow for changes in barometric pressure.

Force Measurements on Airplanes

Description: The most essential phenomena of aircraft should be classified according to their origin and then measured. Information can thus be obtained in a quicker, cheaper, and more reliable way than otherwise would be possible.

Investigation of the Effect of the Fuselage on the Wing of a Low-Wing Monoplane

Description: Memorandum presenting the mutual action of wing and fuselage, which greatly affects the construction of airplanes. A description of systematic wind-tunnel tests that were made to answer that question is provided. Other tests deal with the transition from fuselage to wing root, which, if inadequate on low-wing monoplanes, may become dangerous by causing the air flow to separate at the wing root.

The "Potez 33" Military Airplane (French)

Description: Circular describing the Potez 33, which is a military airplane that can be used for other purposes such as training pilots and as a messenger airplane due to its maneuverability and low landing speeds. A description of the controls, components, potential uses, characteristics, performance, drawings, and photographs are provided.

Pressure Distribution on a Slotted R.A.F. 31 Airfoil in the Variable Density Wind Tunnel

Description: Measurements were made in the variable density wind tunnel to determine the pressure distribution over one section of a R.A.F. 31 airfoil with a leading edge slot fully open. To provide data for the study of scale effect on this type of airfoil, the tests were conducted with air densities of approximately one and twenty atmospheres.

Strength of Tubing Under Combined Axial and Transverse Loading

Description: Note presenting a systematic study of the strength of duralumin and chrome-molybdenum steel round tubing in combined transverse and axial loading. A description of the formulas that are the groundwork for the study as well as the results of the tests are provided.
