Stability Tests of Three Lenticular Models at Supersonic Speeds

Abstract

Force and moment coefficients were obtained on three models of a proposed lenticular rocket shape at Mach numbers 3, 4, and 5 for angles of attack from -5 to +15 deg and a constant Reynolds number of 1.5 million. The variation of the zero-lift drag coefficient with Reynolds number was also obtained for each Mach number over a Reynolds number range from 0.2 to 3.7 million. Visual flow patterns obtained on each model by the china-clay technique showed regions of flow separation at all Mach numbers.
