Abstract (en)
An hydraulic control system, for example for use in moving control surfaces of aircraft, comprises first and second actuators (12A, 12B) operating in tandem. The two actuators are supplied by independent hydraulic pathways (P1, P2), the fluid in each of these pathways being controlled by a plurality of direct drive control valves (4) connected across the two pathways. The system will therefore operate even if three of the control valves, and one of the hydraulic supplies are non-operational.
