Abstract

The inviscid flow on a delta supersonic flying vehicle model, whose lower surface is formed by the surface of a circular cone and has the shape of an elliptical segment in cross section, is computed and investigated in a linear formulation by the method of through-computation. A flow mode with two stream runoff lines and three spreading lines is detected on the lower surface. The spreading characteristics, affecting the conditions for laminar boundary-layer transition into turbulent, are obtained for this surface.
