ASYMMETRICAL AIR-SCOOP FOR THREE FLOW ENGINE OF FASTER-THAN-SOUND AIRCRAFT Russian patent published in 2018 - IPC B64D33/02 F02C7/42 

FIELD: machine building; aviation.

SUBSTANCE: invention relates to inlets of high-speed aircrafts. Asymmetrical air-scoop for a three flow engine of faster-than-sound aircraft contains a spatial vee (1), feedwell (2), side walls (3), subsonic diffuser (6), neck finish and control system of boundary layer. In subsonic diffuser (6) there is axial parting channel (10) with a leading edge (11) of complex shape for draining low-power part of the flow with large losses to outbound of the air-scoop. To control the flow in the internal channel of air-scoop there is a wedgelike opening of draining (4) located in slicing of air-scoop neck finish. Side walls of air scoop are made with a sweepforward of leading edges, located between compression ramps of vee and feedwell. Feedwell is made with a sweepforward of leading edge.

EFFECT: invention reduces weight and increases reliability in a wide range of in-flight parameters.
