Supersonic flow around a blunted body at presence of gas-cooler blowing and oscillations of the wall along the stream

Influence of vibrations and blowing on inviscid drag of a face blunted cone under supersonic flow is studied by theoretical and experimental methods. The problem of nonstationary inviscid flow is solved by S.K. Godunov’s numerical method in the two-dimensional formulation. The results of calculations and experiments show a decrease of inviscid drag at an increase in the blowing parameter and the parameter which describes intensity of vibrations.
