Patent ID: 7264206

Claim:
An aircraft system, comprising: an airfoil; an actuator driver coupled to the airfoil; and a leading edge device having: a first flow surface coupled to the airfoil; a second flow surface coupled to the first flow surface; a first link being pivotally coupled to the actuator driver; a second link being pivotally coupled to the airfoil and to the first link; a third link being pivotally coupled to the second link and to the first flow surface; a fourth link being pivotally coupled to the airfoil; a fifth link being pivotally coupled to the fourth link and to the first flow surface, and wherein: (a) the second link is coupled to both the first link and the third link at a first common point; or (b) both the third link and the fifth link are pivotally coupled to the first flow surface at a second common point; or (c) both (a) and (b); and a sixth link being coupled to the fifth link and the second flow surface.
