摘要：
Results of experimental investigations on supersonic flow past a blunted porous wedge, with air injection into the air stream, are presented. Graphs of distribution of the pressure coefficient and of the relative pressure along the axis of the model are given. The tests were carried out in a hypersonic wind tunnel with air flow at the velocity of M// infinity equals 6 and Re// infinity equals 5. 5 multiplied by 10**7 m** minus **1. The tests show that gas injection results in a considerable redistribution of pressure over the surface of the wedge. Thus, the aerodynamic characteristics of a blunted wedge can be modified to a considerable extent.
