Abstract
An actuator for a control surface is provided. The actuator includes a frame, an electric motor, an epicyclic gear, a power-off brake, a power-on brake, and a unidirectional bearing. A sun gear is operably coupled to an output of the motor. A carrier is couplable to the control surface such that rotation of the carrier in a first direction transitions the control surface toward the deployed position and rotation of the carrier in a second direction transitions the control surface toward the stowed position. The power-off brake couples to the sun gear to ground the sun gear when deenergized. The power-on brake couples to the ring gear to ground the ring gear when energized. When the power-on brake is deenergized, the unidirectional bearing permits the ring gear to rotate in the second direction and prevents the ring gear from rotating in the first direction.
