A MODEL DROP TECHNIQUE FOR FREE-FLIGHT MEASUREMENTS IN HYPERSONIC WIND TUNNELS USING TELEMETRY

Abstract

A technique to provide model pressure and heating rate measurements free from support interference has been developed for the continuous flow, hypersonic wind tunnels (Mach numbers 6, 8, and 10) in the von Karman Gas Dynamics Facility. Data may be obtained from models up to 12 in. in length and 4.5 in. in diameter using onboard telemetry. A description of the test equipment and instrumentation is presented, in addition to base pressure measurements obtained on a 10-deg half-angle cone and base heating measurements obtained on a 10-deg half-angle, rounded base cone at Mach 10.
