METHOD OF INCREASING WING BEARING PROPERTIES FOR HIGH-SPEED REGIONAL AIRCRAFT Russian patent published in 2024 - IPC B64C21/08 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly, to methods of increasing aircraft wing bearing properties. Proposed method comprises suction of air from rear edge of wing main part and from deflected flap tip and blowing of low-pressure jet through flat nozzle at takeoff and landing. Air is sucked off by means of an impeller located in the thickness of the main link of the two-link flap, through an air intake controlled by the inlet area, due to extension of the main link of the two-link flap. Blowing is performed through an area-controlled nozzle due to deviation of the second link of the two-link flap, to the upper surface of the second link, and in cruising flight modes, the impeller is retracted into the thickness of the main part of the wing.

EFFECT: higher wing bearing properties at takeoff and landing while simultaneously ensuring high cruising speed of the aircraft.
