Hot-Wire Measurements of Instability Waves on a Blunt Cone at Mach-6

Abstract

Hot wire calibrations were completed in the supersonic jet facility at Purdue University. This jet consists of a Mach-4 nozzle and allows for a continuous run time. The hot wires were calibrated under conditions similar to those seen in the Mach-6 facility at Purdue University. These hot wires were then used in the Mach-6 tunnel to study the amplitude and growth of instability waves on 7-deg half-angle sharp and blunt cones.
