  • Moving end electronic detection of secondary load path engagement of aircraft flight control actuator
    Patent number: 10933978
    Abstract: A linear actuator, for controlling movement of a control surface of an aircraft, includes a screw, a primary load path and secondary nut engaged with the screw, and an engagement member. The engagement member moves from an ambush position, maintained by the primary load path or the secondary nut, to an engaged position, restricting relative movement between the primary load path and the secondary nut. The restricted relative movement may occur in response to free relative axial movement of the primary load path and the secondary nut caused by a failure of the primary load path of the linear actuator. A sensor of the linear actuator is configured to sense the failure of the primary load path and the free relative axial movement of the primary load path and the secondary nut.
