Complex investigation of nonstationary flow with shock waves in the working path of a hypersonic ramjet engine

Results of a complex experiment-calculated investigation of the structure of a nonstationary gas fl ow in the working path of a hypersonic ramjet engine are presented. Methods of experimental determining the pressure and temperature distributions over the wall of an axisymmetric channel of complex geometry with a sudden widening are proposed and described. The problem on the gas fl ow over a ramjet engine positioned in a wind tunnel was solved.
