Investigation at Supersonic Speeds of the Wave Drag of Seven Boattail Bodies of Revolution Designed for Minimum Wave Drag

August F Bromm, Julia M Goodwin

Abstract

Report presenting an investigation in the 9-inch supersonic tunnel to determine the effects of varying Reynolds number at each of three Mach numbers on the wave drag of seven boattail bodies of revolution designed for minimum wave drag. Results indicated that there was little variation in the pressure distribution with Reynolds number. Results regarding pressure distributions and wave drag are provided.
