A review has been presented of the results of experimental investigations, on a ballistic unit of the Physical-Technical Institute, into the distortion of a bow shock wave and of flow behind the body in CCl2F2 and CF4 polyatomic gases. The latest experimental works at the Physical-Technical Institute and abroad have also been reviewed. The distortion of the bow shock wave under the same conditions is identically manifested in the case of flow past a segmental body and past a sphere alike, although for the sphere, flow separation occurs farther downstream of the bow shock. In the case of flow past a cylinder the initial distribution of the flow is observed in the compression zone behind the bow shock wave.
