Wind tunnel research with a supersonic (M = 2) flow (~ 0.1 m in diameter) and the numerical simulations using the two-dimensional Navier – Stokes equations were conducted to substantiate conditions sufficient to substantially reduce a shock wave intensity at its interaction with a layer of low-density gas. The results of experimental studies of the interaction of a shock wave with a gas layer heated by the combustion of hydrogen and air are shown. Numerical simulations resulted in data about the efficiency of the impact thermal layer/shock wave in a wind range of determining parameters. Also the parameters of the flow in the thermal layer providing substantial reduction in the intensity of the shock wave were determined. Keywords:
supersonic flow, shock waves, physical and numerical simulations.
