AIRCRAFT WING Russian patent published in 2018 - IPC B64C3/50 B64C21/02 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering. Wing of the aircraft includes a sliding slat and the main part of the wing with the outlets of internal feed channels for blowing air jets. Outlets of the internal supply ducts for blowing air jets are located on the portion of the upper surface of the main part of the wing that opens when the slat extends. Axes of the supply channels at the outlets on the wing surface are made at angles 30–60° to the wing surface and angles 30–60° between the projections of the axes on the wing surface and the direction of the flow at the wing surface during the flight of the aircraft. On the lower surface of the main part of the wing there are air intake entrances, that are connected by channels to the outlets for blowing out air jets and are located on the nose portion of the lower surface of the main part of the wing that opens when the slat extends.

EFFECT: invention is aimed at increasing the lifting force with the advanced position of the slat on the takeoff and landing modes with less air consumption, taken from the engine of the aircraft.
