Abstract

The interaction of a shock wave with a blunted body moving with supersonic velocity is considered. It is shown that under certain conditions the reflection pressure at the critical point of the body can be determined on the basis of one-dimensional theory of shock waves. The error due to the application of this theory is investigated. Equations are obtained for the maximum error as asymptotically large values of the number M of the unperturbed stream incident on the body. Conditions under which secondary reflections of the discontinuities at the critical points are possible are analyzed.
