ABSTRACT:
An improved linkage for the control surfaces, e.g., flaps, of a fighter airplane. The wing of the fighter aircraft includes a thin flap which has inwardly extending portions that extend inwardly of the wing of the aircraft by an amount sufficient to allow angular displacement of the flap without interrupting the continuity of the skin thereof. The linkage includes a radial fork having a first arm, a second arm and an intermediate portion intermediate the first and second arms. The intermediate portion is adapted to be pivotally mouted to the wing of the aircraft. The first arm is arcuately configured so that it does not interfere with the arcuate travel of the thin flap. In a similar manner, the second arm is arcuately configured so that it does not interfere with the movement of the extended portions of the thin flap.
