AIRCRAFT ENGINE AIR INTAKE OPERATION METHOD AND AIR INTAKE Russian patent published in 2019 - IPC B64D33/02 F02C7/42 

FIELD: machine building.

SUBSTANCE: air intake (110) of aircraft engine comprises flexible inlet (120) formed of deformable material, which comprises outer surface (211), inner surface (212) and multiple edges (213), which are attached to aircraft fuselage skin (240) and to air intake channel (250) of aircraft engine. There is mechanism (720) configured to change the shape of flexible inlet (120) and a data processing unit (230) configured to control mechanism (720), which comprises a bag and a control joint which is configured to receive a signal from the data processing unit (230), which represents the bag pressure required. Control joint is configured to change the bag pressure to the required bag pressure. Method is characterized by using an air intake.

EFFECT: group of inventions is aimed at improvement of efficiency of air intake of engine at all speeds and reduced radar visibility.
