摘要

A wing tip device (W; W1, W2) for a wing (T; 10a, 10b), comprising aroot (E1) and atip (E2) and the following determinant characteristics: the local dihedral of the wing tip device (W; W1, W2) continuously increases or decreases from the root (E1) to the tip (E2); the local sweep of the trailing edge (50) continuously increases along its progression from the root (E1) to the tip (E2) of the wing tip device (W; W1, W2); wherein the local sweep of the leading edge (60) continuously increases in the progression of the leading edge (60) from the root (E1) to a first intermediate point (61a); continuously decreases from the first intermediate point (61a) to a second intermediate point (62a); and continuously increases from the second intermediate point (62a) at least to a region before of the tip (E2) of the wing tip device (W; W1, W2); as well as a wing comprising a wing tip device (W; W1, W2).
