Keywords: stability, supersonic boundary layer, flow control

DNS of receptivity and stability of supersonic boundary layer over plate, cone, compression corner, wavy surface is performed for solid and porous wall. It is shown that proper designed porous coating and wavy surface can lead to decreasing of disturbances in the boundary layer that may increase laminar run substantially.
