  • Device for regulating and recovering the boundary layer over the surface of a body such as an aircraft in flight
    Patent number: 3951360
    Abstract: In order to control the boundary layer of air over the outer surface of an airframe and to recover some of its energy, portions of this boundary layer are sucked at a multiplicity of locations distributed over this surface and thereafter discharged rearwardly as a jet contributing to propulsion. Such suction takes place through orifices having inlets directed towards the rear and the sucked flow is adjusted so as to draw off only a part of the boundary layer whose velocity relative to the airframe is but a minor fraction of the absolute velocity of the latter, thereby leaving a substantial thickness of boundary layer.
