A backup system is provided that has a local electric motor and pump for some or all of the hydraulic actuators on an aircraft. A local backup hydraulic actuator has two power sources, hydraulic as primary and electrical as backup. During normal operation, the hydraulic actuator receives pressurized fluid from a hydraulic system and the fluid flow to the chambers is controlled by a servo valve. If the hydraulic system fails, the electronic controller detects the failure by observing the signal indicative of the pressure from the pressure sensor, and the ...


The invention claimed is: 1. A flight control system for an aircraft, comprising: a plurality of flight control surfaces movably attached to said aircraft; a plurality of hydraulic actuators coupled to said aircraft, said hydraulic actuators configured to position said flight control surfaces; a first central pressure source providing hydraulic fluid under high pressure to a first group of said plurality of hydraulic actuators; a second central pressure source for providing hydraulic fluid under pressure to a second group of said plurality of hydraulic ...
