Abstract: An actuator is arranged to move an aircraft component such as a landing gear leg, flap or aileron between a first position and a second position, net load from external forces acting on the aircraft component tending to drive it towards the first position. The actuator comprises a threaded screw and a threaded nut. A main prime mover is configured to apply torque to the screw or nut acting in opposition to the net load under normal operating conditions. An emergency prime mover is configured to apply torque to the screw or nut acting in the same sense as the net load under emergency operating conditions in which the interface between the nut and the screw has become partially jammed to the extent that the component cannot be moved from the second position to the first position by operation of the net load alone.

Abstract: A linear drive for adjusting at least one movable structure includes at least one spindle drive having a rotatable spindle. Disposed on the spindle and restrained against rotation is a lifting nut which is linked to the movable structure. At least one safety mechanism is disposed on the spindle without connection to the lifting nut and restrained against rotation. The safety mechanism includes an inner nut attached to the spindle and an outer guide bushing attached onto the inner nut, wherein the inner nut and the guide bushing have an engagement structure which effects a form-fitting engagement between the inner nut and the guide bushing during normal operation and is so constructed as to effect a disengagement between the inner nut and the guide bushing, when the safety mechanism is subjected to a predefined load torque.

Abstract: An electromechanical actuator (EMA) is provided. The EMA includes a threaded output ram connectable to a mechanical component and at least one motor module engageable with the output ram for controllably translating the output ram along a linear axis of the output ram. The actuator further includes a torque sensing adaptive control (TSAC) system for monitoring torque within the motor module. The TSAC generates a disengagement command signal when the TSAC system determines torque within the motor module is outside an allowable motor module torque range. The disengagement command signal initiates disengagement of the motor module from the output ram.

Abstract: A threaded nut is provided for a linear drive having a rotatable spindle. The threaded nut is provided with a main nut, wherein the main nut is intended for being arranged with its internal thread on the external thread of the spindle, and is intended to perform a translatory displacing motion during a rotary motion of the spindle. The threaded nut has, furthermore, a safety nut, which is intended not to mesh by its internal thread with the external thread of the spindle during the normal operation of the linear drive and to mesh with the thread of the spindle in case of failure of the main nut. To make possible simple mounting in case of such a threaded nut means and to reduce the risk for incorrect alignment, the main nut (11) has a first part and a second part. The two parts are located at spaced locations from one another and each part being provided with a threaded section (18a, 18b) of the main nut (11), wherein the safety nut (12) is intended to be arranged between the two threaded sections (18a, 18b).
