Claims (1)

Концевое крылышко, представляющее дополнительную поверхность крыловой формы, имеющая аэродинамический профиль, и установленное на конце крыла, отличающееся тем, что, с целью снижения индуктивного сопротивления и повышения аэродинамического качества на дозвуковых и околозвуковых скоростях полета, на эксплуатационных углах атаки и крыльях с удлинением 2 - 16, концевое крылышко состоит по меньшей мере из трех малых крылышек, установленных одно за другим в горизонтальной плоскости, образующих в плане 1/4 окружности радиусом, равным концевой хорде крыла, и центром окружности, находящимся в точке пересечения задней кромки и концевой хорды крыла, хорда малых крылышек равна b/n, где b - концевая хорда крыла; n - количество малых крылышек, угол установки малых крылышек выбирается оптимальным в зависимости от интенсивности концевого вихря крыла на рассматриваемом участке концевой хорды крыла.An end wing representing an additional wing-shaped surface having an aerodynamic profile and mounted on the wing end, characterized in that, in order to reduce inductive drag and increase aerodynamic quality at subsonic and transonic speeds of flight, at operational angles of attack and wings with 2 - 16, the end wing consists of at least three small wings installed one after the other in the horizontal plane, forming in plan 1/4 of a circle with a radius equal to the end horde wing and center of circle located at the point of intersection of the trailing edge and the end of the wing chord, chord small flaps is b / n, where b - end chord of the wing; n is the number of small wings, the angle of installation of small wings is chosen optimal depending on the intensity of the wing end vortex in the considered section of the wing end chord.
