Claims16
An actuator for an aircraft, the actuator comprising:
- a first motor, a second motor and an actuator output, which are interconnected by a gear assembly, wherein the actuator output is driveable by the first motor independently of the second motor, wherein the actuator output is driveable by the second motor independently of the first motor;
- and wherein the actuator output is driveable by the first and second motors in combination.
A method of operating an actuator comprising a first motor, a second motor and an actuator output, which are interconnected by a gear assembly, the method comprising:
- operating the first motor to drive the actuator output;
- operating the second motor to drive the actuator output in the event of a fault with the first motor;
- and
- operating the first and second motors in combination to drive the actuator output in the event of a fault with the gear assembly that interconnects the first and second motors.
