Abstract:

A combined analytic-experimental investigation of the subsonic base pressure phenomenon, especially as applied to blunt bodies typical of hypersonic flight vehicles, results in the development of a generalized method to predict base pressure in three-dimensional flow at subsonic speeds. A mathematical description of the fluid mechanics of steady two-dimensional subsonic base flow is developed. Two and three-dimensional wind tunnel testing of blunt based configurations is used to verify the two-dimensional analytic solution and obtain empirical relations which extend the analysis to three-dimensional base flow.
