A trailing edge flap moveable from a stowed position behind a wing to a downwardly and rearwardly extending position to deflect jet exhaust from an upper surface blowing jet engine downwardly and rearwardly to augment lift. The actuating mechanism rotates the flap about a variable radius which maintains the upper surface of the flap in contact with and generally in tangential alignment with the trailing edge of the upper surface of the wing. This mechanism comprises forward and rear radius links pivotally mounted at their lower ends to a stationary mounting arm, and extending upwardly and divergently therefrom to attach to the flap. In two embodiments, the rear radius link has its pivot end mounted to a moveable member which in turn enables the flap to be rotated so that its forward end moves downwardly. Thus, in its fully deployed position, the flap can be rotated to form a slot between the aft end of the wing and the leading edge of the flap.
