Abstract: An actuation apparatus for a control surface rotatably coupled to a swept-wing includes a pivot arm coupled to the control surface and proximate the hinged end of the control surface, a drive rod oriented normal to the trailing edge of the swept-wing, the drive rod having an aft end coupled to the pivot arm, a pivot fitting pivotally coupled to a lower surface of the swept-wing by a pivot pin, the pivot fitting having an aft portion coupled to a forward end of the drive rod, and an actuator disposed on the lower surface of the swept-wing. The actuator is coupled to the pivot fitting such that an applied force by the actuator in the streamwise direction rotates the pivot fitting such that the applied force is translated to the drive rod to rotate the control surface.

Abstract: Described herein is an auxiliary support system for a flap coupled to a wing of an aircraft. The auxiliary support system comprises a base fixable relative to the wing. The auxiliary support system also comprises a first track engagement assembly fixed to the base. The auxiliary support system further comprises a second track engagement assembly fixed to the base. The auxiliary support system additionally comprises a track arm attachable to the flap and comprising a first rail, movably engaged with the first track engagement assembly, and a second rail, movably engaged with the second track engagement assembly. The first rail is spaced apart from and non-parallel to the second rail.

Abstract: Aerodynamic seals for use with control surfaces on aircraft are described herein. In one embodiment, a seal assembly for use with an aircraft includes a first seal member and a second seal member. The first seal member has a first proximal portion configured to be attached to a fixed airfoil portion of the aircraft, and a first distal portion configured to extend outwardly from the fixed airfoil portion toward a movable control surface. The second seal member has a second proximal portion configured to be attached to the movable control surface, and a second distal portion configured to extend outwardly from the control surface toward the fixed airfoil portion. In this embodiment, the second distal portion is further configured to movably contact the first distal portion to at least partially seal the gap between the fixed airfoil portion and the movable control surface as the control surface moves relative to the fixed airfoil portion.
