Supersonic Flow Past Conical Bodies with Nearly Circular Cross-Sections.

Abstract

Inviscid, supersonic conical flows past bodies whose cross-section deviates slightly from that of a right circular cone are studied by means of a perturbation technique. The effects of small angles of attack and yaw are included. Using the hypersonic small disturbances theory approximations, we have developed explicity results for the flow field velocity components, pressure, entropy, and shock shape for cases n, m = 1, 2, 3, 4. Comparisons of theory with experiment for n = 1, 2 are favorable. The streamsurfaces of the velocity field are calculated and possible waverider geometries that can be developed therefrom are discussed.
