Abstract : Heat transfer rates using calorimeter sensors, and pressures using variable reluctance diaphragm transducers, have been measured on five model shapes at Mach numbers of 15 and 20 and over a unit Reynolds number range of 2 million to 7 million per foot. Two basic shapes, a hemisphere and a half-angle biconic configuration with and without nose bluntness, were tested with different surface roughness. The results are reported and discussed.
