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.

An improved linkage for positioning a control surface pivotally mounted to an airfoil of an aircraft wherein the control surface has a linkage compartment at a forward end thereof, the linkage compartment having a substantially curvilinear outer shell portion that extends inwardly of the airfoil on the top and bottom thereof, the linkage for pivoting the control surface such that at least a portion of the outer shell of the linkage compartment is interior of the outer shell of the airfoil for all angular displacements, said linkage comprising: actuator means coupled to the airfoil for providing a drive force to pivot the control surface; and linkage means responsive to the drive force provided by said actuator means for positioning the control surface, said linkage means being pivotally coupled to the airfoil at a first pivot point and to said actuator means at a second pivot point spaced from said first pivot point, said linkage means being shaped to extend interior of the linkage compartment and being pivotally coupled to the control surface at a third pivot point spaced from said first and second pivot points to pivot the control surface in response to the drive force provided by said actuator means.
