Linear stability of compressible boundary layers is studied theoretically. First examined is the stability of three-dimensional boundary layers represented by a family of the Falkner-Skan-Cooke profiles to stationary disturbances at Mach numbers 0.2 and 2.0. The characteristics of stationary instability modes are found to be little influenced by the compressibility when the cross-flow instability is dominant. Next examined is the development of wave disturbances from an oscillating point source in two-dimensional boundary layers at Mach numbers from 0.2 to 2.0. The kinematic wave theory is applied to describe the wave propagation. The analysis clearly dimonstrates the differences in the development of the excited waves between the subsonic and supersonic boundary layers.
