N2 - The linear stability of the boundary layer at high supersonic Mach numbers on a flat plate with a cooled porous surface is studied. As is well known, at high supersonic speeds, both vortex disturbances of the first mode and acoustic disturbances of the second mode are unstable. The more unstable disturbances of the second mode can be stabilized using sound-absorbing porous coatings. At the same time, such coatings have a destabilizing effect on the disturbances of the first mode. Surface cooling is one of the factors potentially capable of preventing such a destabilization. Based on this assumption, in the present work, the linear theory of stability is used to consider the combined effect of a sound-absorbing coating and surface cooling.
