Abstract
A flight control actuator drive including a first motor for providing a first rotational input, a second motor for providing a second rotational input and a speed summing device for combining the first and second rotational inputs into a rotational output for controlling an actuator. The speed summing device comprises first and second input gears to which the first and second motors are connected via first and second irreversible gears so that the first and second input gears can each transmit power in one direction only. The speed summing device may be a planetary gear assembly.
