Abstract

An actuation mechanism, a flap mechanism, and an aircraft. The actuation mechanism includes drive links and drive mechanisms connected to opposite ends of the flap that move the flap to various positions. The drive mechanisms are actuated by torque tubes connected to a drive motor via a differential. The differential distributes torque to the torque tubes. In the event of abnormal operation of one of the drive links or drive mechanisms, the differential limits torque to the remaining drive link and drive mechanism such that the flap does not deploy or retract in a skewed manner.
