ABSTRACT:
An aerofoil body, for example a "delta" wing aircraft, in which strip-form devices project rearwards from the trailing edge of the wing and serve to improve the lift-to-drag ratio of the body, in some conditions of flight at least, by modifying the formation of the trailing edge vortex to allow the axes of the primary vortex sheets to lie closer to the fore-and-aft centerline of the body than would otherwise be the case. When the strips are basically flat in shape, the strips may project straight backwards from the trailing edge or may be angled in various ways. The use of twisted strips is also described.
