Abstract

A hypersonic tunnel, in which the highest known unit Reynolds numbers are attained, has been developed. In this facility the test gas is compressed by a free flying piston in a thermodynamically-slow multiple-shock reflection process and trapped by one-way valves before it is expanded in a conventional nozzle.
Pressure, heat transfer and Pitot pressure profiles were measured on wedges and cones at Mach numbers from 17 to 22 and at Reynolds numbers up to 4 million. The results are in agreement with viscous interaction theory and are of practical interest to the designer of hypersonic cruise and reentry vehicles.
