Abstract

The problem of optimization of gasdynamic variables behind a system of two steady oblique compression shocks with restrictions imposed on the flow-defection angle is considered. The intervals of input parameters, in which this system turns out to be more effective than one shock, are determined. On the basis of an analysis of the system optimal for the static pressure, the physical meaning of the transition from one type of the reflected discontinuity to another is explained for the problem of interaction of overtaking oblique compression shocks.
