WING OF AN AERIAL VEHICLE Russian patent published in 2022 - IPC B64C3/10 

FIELD: aircraft.

SUBSTANCE: invention relates to wings of subsonic aerial vehicles. The wing of an aerial vehicle comprises a centerwing and panels, made with an elongation λ=9÷12, sweep χ=10÷35°. The trailing edge in the area from 0 to 33% of the wingspan is made with a strake. The relative thickness of the airfoil is 14÷17% in the side section, 11% in the centerwing section, and 8÷10% in the end section. The connection of the centerwing and the panel is made with a smooth coupling of 37 to 40% of the wingspan, made with a geometric twist ε=3.0°÷3.5° in the side sections and a geometric twist ε=(-4.0°)÷(-4.5°) in the end sections.

EFFECT: invention is aimed at increasing the maximum aerodynamic quality, the value of maximum permissible lift coefficient, improving the fuel efficiency index, reducing the emission of hazardous substances into the atmosphere, and reducing the noise level in the area.
