Liebherr on board the AW189
Leonardo Helicopters features systems from three Liebherr’s product lines: air management systems, flight control and landing gear systems. This helicopter demonstrates how integration capabilities and highly engineered systems lead to a perfect result.
The AW189 is a 8.3 tons twin-engine helicopter, designed to answer the growing market demand for a versatile, affordable, multirole platform. It is produced by Leonardo Helicopters.
Designed with inherent multi-role capability and flexibility of operation, the AW189 is capable of carrying up to 19 passengers at very high speed, in a spacious and comfortable cabin.
Liebherr is a major supplier of the AW189, through three product lines:
Air management system
Liebherr supplies the cabin air conditioning system using a vapour cycle system. The compressors are electrically-driven and power a two zones cabin and cockpit air cooling system. In cold conditions, a heating system fed by air bled from the engines provides warm air to the passengers.
Liebherr supplies all components of the system including heat exchangers, valves, the controller, and the cockpit panel to select the temperature to be supplied automatically for the passengers' best comfort. Liebherr also supplies the AW189 cabin and cockpit air distribution which includes ducts, valves, fans, diffusers and gaspers.Learn more about Liebherr air management systems
Flight control system
Liebherr has developed the fly-by-wire main and tail rotor actuator for the AW149 so that they fit in the AW189. The fly–by-wire system allows for superposition of the pilot inputs with additional control inputs for trim or auto control. They are mainly responsible for improving the pilot’s comfort and are supporting a safe flight. The main advantages of fly-by-wire are an easier integration of complex control and protection functions.Learn more about Liebherr flight control systems
Landing gear system
Liebherr supplies the complete landing gear system of the AW189. This includes everything from the landing gear control panel with the lever installed in the cockpit up to the wheels and brakes installed on the retractable landing gear legs. Liebherr also provides the helicopter's landing gear extension and retraction system, including actuators, the hydraulic valve and position switches.Learn more about Liebherr landing gear systems
