Abstract
Power takeoff means () for this flight control system adjacent to the aircraft engines () are all-electric and this makes it possible to reduce the length of hydraulic connections leading to actuators of the controlled devices (). Electrical generators are of different types to minimize the risk of a generic failure. Characteristically of the invention, some generators () have a constant voltage to frequency ratio and directly or almost directly control electro-hydraulic pumps (), without modifying the current characteristic and with no power electronics. Furthermore, system reconfigurations are made possible by additional electrical connections () in case of failure.
