Miniaturized compact water-cooled pitot-pressure probe for flow-field surveys in hypersonic wind tunnels
Author and Affiliation:
Ashby, George C.(NASA Langley Research Center, Hampton, VA, United States)
Abstract: An experimental investigation of the design of pitot probes for flowfield surveys in hypersonic wind tunnels is reported. The results show that a pitot-pressure probe can be miniaturized for minimum interference effects by locating the transducer in the probe support body and water-cooling it so that the pressure-settling time and transducer temperature are compatible with hypersonic tunnel operation and flow conditions. Flowfield surveys around a two-to-one elliptical cone model in a 20-inch Mach 6 wind tunnel using such a probe show that probe interference effects are essentially eliminated.
