US Patent 11408491 Electromechanical actuator assembly

An electromechanical actuator assembly comprises a first actuator and a second actuator. The first actuator and the second actuator are coupled together end-to-end and are independently operable. A method of actuating a moveable element using an actuator assembly, comprises: coupling a first actuator between a fixed structure and a second actuator so that the first actuator is operable to move the second actuator relative to the fixed structure; coupling the second actuator to the moveable element; and moving the moveable element by moving the second actuator using the first actuator.
