Abstract : A large body of wind tunnel data was generated by tests of missile bodies of varying ellipticity ratios. The tests were conducted at subsonic through high supersonic speeds at angles of attack from -4 to 20 degrees. Measurements of both surface pressure and total forces and moments were made at a variety of Mach numbers and Reynolds number combinations. This data was supplemented with flow visualization data such as vapor screens, oil flows and shadowgraphs at selected supersonic Mach numbers. The missile bodies were power-law bodies with an exponent of 0.5 and ellipticity ratios of 2.0, 2.5, and 3.0 to 1. Comparisons of selected data with various prediction codes (Supersonic/Hypersonic Arbitrary Body Program, NSWC Euler Code, Missile Datcom, and FLO-57 Euler Code) were made. The test data provided insight into the effects of several variables and will provide a good data base for correlations with numerical techniques.
