Wing i.e. airfoil wing, end form for wing of commercial aircraft, has transition area arranged between wing and winglet, where local V-form changes continuously from wing to winglet in transition area

摘要

The wing end form has a profile running transversely from front edges of a wing (1) to a rear edge of the wing, where the profile extends into a wingspan direction of the wing. A transition area (2) is arranged between the wing and a winglet (3), and extends from an attachment at the wing to an attachment at the winglet. A local V-form changes continuously from the wing to the winglet in the transition area, where a curvature of the V-form increases strictly and monotonously with a wingspan in the transition area. The wingspan is associated with constant increase of the V-form.
