Abstract: A slat support apparatus and a slat track for an aerodynamic surface of an aircraft. The slat support apparatus includes at least one support rib member fixedly coupled in the aircraft wing, a slat track body to advance the slat relative to the aerodynamic surface between a stowed position and a deployed position, a slat track body including a pair of spaced-apart slot openings; and a pair of support rollers fixedly coupled to the at least one support rib member and arranged in the pair of spaced-apart slot openings to support the slat track body for movement along an arcuate path of travel along a longitudinal axis of the slat track body between a retracted position that maintains the slat in the stowed position and an extended position that advances the slat away from the aerodynamic surface.

Abstract: A system for driving a slat of an aircraft wing includes a primary support, an auxiliary support, an actuator support, and an actuator. The primary support is rotationally coupled to the slat at a forward slat revolute joint for moving the slat between a retracted position and one or more extended positions. The auxiliary support is coupled to the slat for pivoting the slat about the forward slat revolute joint when the slat moves between the retracted position and the one or more extended positions. The actuator support is coupled to the slat. The actuator is coupled to the actuator support at an aft slat revolute joint for driving the slat between the retracted position and the one or more extended positions.

Abstract: Structural composite airfoils include a primary structural element, a secondary structural element defining the trailing edge of the structural composite airfoil, and a discrete leading edge structure defining the leading edge of the structural composite airfoil. The primary structural element includes an upper skin panel, a lower skin panel, and a middle C-channel spar that is coupled to the upper skin panel and the lower skin panel. The discrete leading edge structure is coupled to the upper leading edge end of the upper skin panel and to the lower leading edge end of the lower skin panel. The upper skin panel may include a first panel bend adjacent the discrete leading edge structure, and the lower skin panel may include a second panel bend adjacent the discrete leading edge structure.
