Abstract:

An investigation was conducted in a hypersonic shock tunnel to determine the local heat transfer rates for a sharp leading edge flat plate. The free stream Mach number range was 7.95 to 25.l with stagnation temperatures of approximately 2550 and 6500 R. For these temperature and Mach number conditions, the strong interaction parameter varied from 2.35 to 826. The corresponding Knudsen numbers, based on the ratio of the free stream mean free path and the leading edge thickness, varied from 0.38 to 85.5. The sputtered platinum heat gages were dynamically calibrated by passing a moderate strength shock wave across the gages and observing the change in resistance due to a step function temperature rise. By this method the gage characteristics were determined for the same pressure rises encountered in the test section.
