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 l...


A device for controlling the thickness of the boundary layer of a flow of ambient fluid over the surface of a hollow streamlined boDy extending fore-and-aft from a leading edge to a trailing edge, comprising means for maintaining the thickness of the boundary layer contiguous with said total of said surface at maximum value compatible with laminar flow conditions over said surface including a multiplicity of counter-ramming intakes pointing in a rearward direction at substantially right angles with the normal to said surface of said body, substantially u...
