Abstract: A screw type linear actuator that includes a system for automatically fixing the nut in an axial position when it is retracted. When the system is commanded to operate the screw, the nut can automatically unlock. When the system screw is retracted fully, it automatically engages a mechanical lock. The lock does not require electrical power to remain engaged.

Abstract: A compact, efficient, and reliable electromechanical actuator that is capable of driving heavy loads at a high rate of speed and also capable of resisting large back driving forces. The actuator resists tension and compression back driving forces in a static state as well as when the actuator extends and retracts. The back driving forces are resisted even if the electronics (e.g., motor) fail.

Abstract: The present disclosure relates to a flight control device that can be mounted to a body of a wing of an aircraft to reduce or eliminate backlash in electromechanical actuators (EMAs). The flight control device can include a flight control member and first and second actuators for moving the flight control member relative to the wing of the aircraft. The first and second actuators can be mechanically isolated from one another except for their mutual connection to the flight control member. The first and second actuators can cooperate to apply torsional loading to the flight control member about an axis of the flight control member to reduce or eliminate backlash.

Abstract: Aspects of the present disclosure relate to a skewed roller impeller cage including a metallic ring with radially arranged slots in which rollers are positioned. Impeller shaped channels are defined around a top side of the cage to force fluid to circulate from an outer diameter of the cage to an inner diameter of the cage and vice versa. Cutouts defined at the inner diameter of the cage allow fluid to circulate from the top side of the cage to the bottom side due to centrifugal forces moving the fluid from the inner diameter back to the outer diameter of the cage to allow for continuous circulation of the fluid about the cage.
