초록

The present invention relates to a wing tip extension (7) for a wing, having an upper and a lower surface (10and11) and a leading edge and a trailing edge (12and13), the geometries of which are such that between a connection region (8), for connection with a wing, and the tip (9) of the wing tip extension (7) there is provided a continuous increase of the local dihedral, a continuous increase both of the sweepback angle of the leading edge (12) and also of the trailing edge (13), and a continuous decrease of the chord of the wing tip extension (7), and i...
