The paper considers features of regulating shock-wave structures using the gas blowing into the flow region from perforated boundaries, as well as by means of energy supply to the compression shocks. Scientists both in our country and abroad are actively studying the porous structures. Calculations in the gas dynamics software packages and using the MATLAB are making it possible to determine the flow blowing effect on rearrangement of the emerging shock-wave structures, which analysis with mathematical apparatus of the shock (detonation) polars allows evaluating their diversity with the pulsed energy supply to the compression shocks. Methods of these structures regulation under study contribute to improving characteristics of the supersonic aircraft and creation of their modernized designs taking into account transformation criteria of the shock-wave structures, which in many cases could be unstable.
