FIELD: aviation.
SUBSTANCE: versions of the winglets are made with possibility of attachment to aircraft wing. Winglet smoothly passes from wing end above plane of wing chords and can have underwing stabilizer protruding below plane of chords from lower surface of upper winglet. Upper winglet can have transition section bent upward from wing end to transition into substantially flat section. Upper and lower surfaces of top winglet can be limited by front and rear edges, which are deflected in direction of air flow, parallel to plane of chords, and are bent in direction of air flow, terminating at point far from wing end. Upper and lower surfaces of underwing stabilizer can be limited by front and rear edges, which are bent in direction of air flow and terminate at point, far from wing end. Versions of the winglet modification method characterize the manufacturing process using the curved blade.
EFFECT: group of inventions is aimed at reduction of inductive resistance.
