AIRCRAFT WING Russian patent published in 2020 - IPC B64C3/10 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering and can be used in designing subsonic aircraft wings for various purposes. Aircraft wing consists of center section and cantilever, extension elongation λ=7–12, sweep χ=10–35° and comprises supercritical profiles. Aircraft wing is characterized by that the rear wing edge has a sweep in range of 0–5°, in range from 0 to 33 % of the wing span is made with an influx, in area from 27 to 35 % of span of wing, the rear edge has section of conjugation of center section and cantilever made according to law of two conjugated surfaces, sweep of the console at section from 27 to 100 % of span has sweep along leading edge 10–17°.

EFFECT: invention is aimed at reducing the value of the coefficient of resistance.
