Abstract
A new hinge fairing design for control surfaces such as ailerons, elevators, and rudders. By staggering the two curved hinge fairings, one mounted to the fixed airfoil and the other to the leading edge of the control surface, a curving load path is opened up that allows installation of hinge fittings and actuators without having to make cut-outs in the curved fairings. This principle makes it possible to keep the control surface faired and sealed over its entire span and during its entire motion range. This improves the effectiveness of the control surface. The principle of the present invention is applicable to trailing edge control surfaces of subsonic and supersonic airplanes and is of particular benefit for hinged leading edge flaps on a supersonic commercial transport.
