Abstract

Abstract : Pressure measurements were obtained on five miniature Mach/flow angularity (MFA) probes which were developed at AEDC as part of an on-going probe development effort. These measurements will be correlated with Mach number and known flow angle in order to calibrate these probes. Secondary objectives were to test a hot-film anemometer and three pitot acoustic probes for durability, and to examine the response of three ported dynamic pressure transducers located downstream of the tunnel test section.
