Description

The primary flight control system is part of the complete function needed to pilot an aircraft. It is actuating three sets of movable surfaces of the airframe - aileron, rudder and elevator. Liebherr supplies such control systems including actuators and electronic controllers. Fly-by-wire Fly-by-wire technology is part of the systems that Liebherr offers for new applications. Actuators can be hydraulically or electrically driven depending on the aircraft architecture. Latest technology electro hydraulic actuators (EHA), electric back-up hydraulic actuators (EBHA), or electro-mechanical actuators (EMA) have been successfully integrated into the Liebherr product portfolio. Tail rotor actuator, part of the fly-by-wire flight control system developed for the NH90 helicopter. Tail rotor actuator, part of the fly-by-wire flight control system developed for the NH90 helicopter. Main rotor and tail rotor actuation Helicopters are controlled in their flight by acting on the rotor blades whether from the main rotor or from their tail rotor. This is achieved with dedicated actuators mostly hydraulically driven. Liebherr develops and produces actuators for main and tail rotor as well as complete systems including actuators and actuator controllers. Having developed one of the first fly-by-wire flight control systems for helicopters, Liebherr also has extensive experience in this area.
