  • Abstract
    An experiment was conducted in the Wright Research and Development Center 20-in. hypersonic wind tunnel to assess nonisentropic effects on the test section Mach number. Pressure measurements were made on a blunt 5° cone. These pressures were then compared with a parabolized Navier-Strokes code to define the free-stream Mach number. The results indicate that the nonisentropic effects are not significant. There is no pronounced difference in the Mach number from that determined by the more conventional Pitot pressure probe survey
