摘要： A variable camber leading edge device (10) having a movable nose section (22) and an upper flexible panel (28) extending rearwardly from the nose section. To move the nose section between its upper cruise position and a high lift downwardly deflected position, there is attached to the nose section a generally arcuate cam track (46), having its formward (49) and rear portions (50) curving upwardly. The cam track is constrained to move in a generally arcuate path (80) but with a movable center of rotation (82), and is driven by a gear (68) engaging a radially outward rear portion (70) of the track.

摘要： An aircraft leading edge slat (11) is biased when at an extended location toward a first position wherein the trailing edge (19) of the slat is a predetermined distance from the wing upper surface. The slat is pivotable to a second position, when aerodynamic forces acting on the wing overcome the biasing force, wherein the slat trailing edge is pivoted upward and forward and the distance between the slat trailing edge and the wing upper surface is increased. The slat is retracted and extended by a drive track (12) which is supported inside the wing by upper rollers (18) located chordwise within the wing cavity, a lower front roller, and a pair of roller rings (90) rotatably mounted at opposite sides of a rotary actuator pinion gear (86). The pinion gear engages the drive track and moves the slat between the extended and retracted positions.

摘要： A leading edge wing slat having a movable nose portion (11) wherein the nose portion leading edge moves relative to the slat frame (12) in a downward and rearward direction when the slat is extended. This causes an intermediate flexible upper skin panel (14) 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 (106, 108) 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.

摘要： A leading edge/anti-icing assembly for an airfoil comprising a leading edge slat having a nose section defining a heat exchange chamber. Anti-icing air directed into the heat exchange chamber flows rearwardly through the slat so as to have a deicing function, and is then discharged in a rearward direction from the trailing edge of the slat. Thus, the anti-icing air not only performs an anti-icing function over the upper surface of the slat, but also contributes to anti-icing over the upper surface portion of the main wing rearwardly of the trailing edge of the slat.
