FIELD: aviation.
SUBSTANCE: invention relates to the aviation equipment. Aircraft wing consists of center section, console and sweep χ=28–35°. Relative thickness of profiles has value of 14–16 % in onboard section and value of 11–12 % in sections of 30–40 % of wingspan. There is positive swirling ε=2–5° in bead section. End sections are designed with negative swirling ε=-2÷-5. Upper wing surface has long linear character in range of 15–80 % of chord, and maximum relative thickness of wing in range of 35–45 % of chord.
EFFECT: invention is aimed at increasing aerodynamic quality.
