AIRCRAFT WING Russian patent published in 2021 - IPC B64C3/10 B64C39/10 

FIELD: aeronautical engineering.

SUBSTANCE: invention relates to aeronautical engineering. The wing of the aircraft consists of a center section and consoles made with a single leading edge without a break with a sweep χ=28÷35°. Each cantilever is connected to the center section with a kink along the trailing edge and has a kink in the trailing edge at a distance of 35÷50% of the wing half-span from the central axis. The relative thickness of the center section profile has a value of 14÷16%, and the relative thickness of the cantilever profile is 11÷12% in the section from the center section to the cantilever fracture, which is made with a positive twist ε=2÷5° in the section 0÷10% of the wing half span. The end sections in the section of 50 - 100% of the wing half-span are made with negative twist ε=(-2)÷(-5)°.

EFFECT: invention increases aerodynamic quality, improving fuel efficiency and reducing harmful emissions into the atmosphere.
