Abstract
Efficient wing tip devices for use with aircraft wings. In one embodiment, an aircraft wing/winglet combination includes a wing having a wing root portion and a wing tip portion spaced apart from the wing root portion. The wing tip portion can have a wash-out twist relative to the wing root portion. The aircraft wing/winglet combination can further include a winglet extending from the wing tip portion of the wing. The winglet can be swept at least generally forward relative to the wing to favorably change the lift distribution on the wing and in turn reduce the induced drag on the wing.
