Design and calibration of a total-temperature probe for use at supersonic speeds

Description: Report presenting a study of the factors involved in the design of total-temperature probes for use at supersonic speeds as applied to the design of an instrument to be used in wind-tunnel calibrations. Tests of the probe showed that the calibration factor required in the conversion of the measured temperature to the true total temperature was 0.992 for a range of Mach numbers.

Development of detonation detector suitable for use in flight

Description: Report presenting an apparatus for making quantitative measurements of the vibrations excited by detonation in the cylinder head of an aircraft engine. The apparatus consisted of pick-up units, an amplifying system, and a cathode-ray oscillograph with a high-speed-camera recording system. A large number of records were taken under various operating conditions in a single-cylinder aircraft engine.

Velocity Distribution on Wing Sections of Arbitrary Shape in Compressible Potential Flow 1: Circulatory Flows Obeying the Simplified Density-Speed Relation

Description: "As a first step toward the computation of the velocity distribution along a wing profile of arbitrary shape in a compressible fluid, the circulation-free flow around a symmetrical profile is treated under the assumption of the simplified density-speed relation due to Tchaplygin, Karman, and Tsien. The velocity distribution problem is reduced to a non-linear integral equation which is solved by a fairly rapidly convergent iteration method. Numerical examples are given" (p. 1).
