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: 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: Various flight control components can be operated through gearbox driven rotary actuators. In the event of a jam occurring the gearbox, the gearbox can be decoupled from a surrounding support housing to enable free-trailing or limited motion relative to the support housing. The motion may or may not be damped. Decoupling the gearbox enables the flight control component to move to a neutral or non-interfering position even when user control over the component has been lost.

Abstract: An electric motor-brake assembly includes a housing within which a rotor assembly, a stator assembly, and a brake assembly are disposed. The brake assembly is operable between an engaged state and a disengaged state. The rotor assembly is axially movable within the housing and is supported by bearings supporting both radial and axial loads. When the motor stator is de-energized, the brake assembly is in the engaged state to prevent the rotor assembly from rotating in at least one rotational direction. When the motor stator is energized, the brake assembly is in the disengaged state such that the rotor assembly is free to rotate. The brake assembly can include a friction pack that is engaged and disengaged by axial displacement of the rotor assembly.
