FLOW QUALITY IMPROVEMENT AT MACH 8 IN THE VKF 50-INCH HYPERSONIC WIND TUNNEL B

C. R. Fitch

Abstract

Abstract : Flow quality within the 50-in. hypersonic tunnel at a nominal Mach number of 8 is discussed. The nozzle and throat were recently remachined to closer tolerances which resulted in improved test section flow quality. Measurements of the contoured nozzle ordinates and Mach number distributions are presented along with results from method of characteristics solutions of design and actual measured wall contours.
