Nonlinear Analysis of Interfering Bodies in Supersonic Flow.

Abstract

This report describes a study of the flow field about interfering bodies in a supersonic stream and is directed toward the prediction of supersonic store carriage/separation. The development of computational techniques aimed at producing a usable code is discussed. The code includes a characteristic based finite difference scheme to solve Euler's equations and a new and general shock fitting scheme. One problem uncovered during this first years effort is that of transition from a regular reflection to a Mach disc shock configuration. The basic finite difference scheme has been exercised extensively and was proven sound. More importantly the new shock fitting scheme is able to predict complex interactive shock patterns.
