Abstract
A study of the effect of distributed gas with high specific heat capacity blowing into the supersonic boundary layer on its stability to artificial disturbances was conducted. It is shown that the injection of gas with high heat capacity Cp at certain flow values can lead to the stabilization of the supersonic boundary layer.

Keywords
