Abstract

See full text

A leading edge wing slat having a movable nose portion wherein the nose portion leading edge moves relative to the slat frame in a downward and rearward direction when the slat is extended. This causes an intermediate flexible upper skin panel attached between the nose portion and a rigid rear portion of the slat to have its curvature increased thereby increasing the camber of the upper surface of the slat. During retraction of the slat, the nose portion leading edge moves upward and rearward relative to the slat frame decreasing the curvature of the intermediate flexible upper skin panel. The nose portion includes a cam plate having cam slots which are engaged by rollers rotatably connected to the slat frame. Extension of the slat causes the cam plate as programmed by the cam slots to move the nose portion relative to the slat frame to achieve the desired slat camber.
