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.
