Abstract
A flight control surface actuation system is provided in which a plurality of actuators (6-13) are connected to one another in order to synchronize their operation. Each actuator has its own gearbox such that the torque transmitted in the synchronizing element is kept low.
Claims14
A flight control surface actuation system, comprising at least three linear hydraulic actuators which control the position of aircraft flight surfaces, and in which each actuator is mechanically synchronised with the other actuators via a synchronising element such that a motion of a first actuator in advance of that of a neighbouring second actuator causes the first actuator to be braked thereby allowing the second actuator to catch up while not driving the second actuator through the synchronizing element.
