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 flow 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 flow over a ramjet engine positioned in a wind tunnel was solved. [ABSTRACT FROM AUTHOR]
