Abstract
The results of hot-wire measurements of periodic controlled disturbances of the mass flow beyond the boundary layer on a flat plate are discussed, and their wave characteristics reflecting the acoustic properties of the supersonic boundary layer are estimated. The possibility of emitting subharmonic disturbances at a Mach number of 2.5 is demonstrated for the first time.
