An aircraft wing has a winglet extending from the tip to reduce drag and thereby improve the efficiency of the aircraft. Hitherto such winglets, although they have succeeded in reducing drag, they have also increased the wing bending moment at high coefficients of lift sufficient to require a strengthened and therefore heavier wing. Moreover, they have suffered flow break-away at such high coefficients of lift and have therefore incurred aircraft control problems. A winglet according to the present invention, is of high sweep back and low Aspect Ratio. I...
An aircraft wing including, main wing means (1) having a median plane (X－X) and a wing tip region of specified chord having a leading edge region (3) and a trailing edge region (4) and winglet means (2) extending upwards and/or downwards from the median plane (X－X) of said wing tip region, the winglet means having a root region (5) with both a forward extremity (6) and a rearward extremity (7) in the region of the median plane, the forward extremity of the winglet means lying at or rearward of the leading edge region of the main wing means, a tip region ...
