A wing assembly has a wing and at least one slender delta shaped flap with sharp leading edges pointing into the flow direction and deployable above the upper wing surface close to the quarter line of the wing for providing significantly enhanced lift and maneuverability to an aircraft. In normal flight the delta flaps are retracted into the wing such that the upper surface of the delta flaps become part of the upper surface of the wing. If higher lift is required or the wing has stalled, the delta flaps are deployed at an angle of attack into the high e...
[ Having thus set forth the nature of the invention, what is claimed herein is:] [1.] A flight lifting surface assembly for aircraft comprising in combination, a wing including upper and lower surfaces extending lengthwise intermediate a leading edge and a trailing edge and at least one flap, said flap having a delta shaped configuration including an apex extending into the flow, a pair of leading edges extending from the apex and terminating at a trailing edge, said flap having upper and lower surfaces converging at a small angle to define sharp leading...
