a unique technology at the service of major aeronautical programs

Liebherr-Aerospace & Transportation employs approximately 6,000 people worldwide, including 1,500 in the Toulouse region, in five businesses: air systems, landing gear, flight controls, transmissions and on-board electronics. The company supplies major systems on most of the major worldwide aeronautical programs of Airbus, Boeing, COMAC, Dassault Aviation, Embraer, Leonardo Helicopters or Rolls-Royce.

The long-term vision of the exclusively family shareholding of the Liebherr Group allows Liebherr-Aerospace & Transportation to invest, on a continuous and sustained basis, amounts above the industry average, both in its facilities and in research. and development.

These investments equip Liebherr with the means of production, digital systems and technologies that allow it to make a substantial contribution to the success and the decarbonization initiative of the aviation sector. Liebherr is a first-class partner of major aircraft and aero-engine manufacturers and offers them numerous technologies necessary for the performance and reduction of the carbon footprint of their aircraft, such as:

  • The next generation UltraFan® high bypass ratio engine power reduction box, from manufacturer Rolls-Royce
  • The wingtip deployment and locking system of the Boeing 777X, the newest member of Boeing’s wide body family
  • The air supply compressor for hydrogen fuel cells
  • On-board electronics cooling and electric power conversion systems that accelerate the deployment of the more electric aircraft
  • Key components of the payload cooling loop of the Space Inspire family of satellites from Thales Alenia Space

Liebherr designers are working hard to find out how to replace these hydraulic systems in the future with electromechanical or electro-hydrostatic systems. They stay the course towards the next generation of aircraft: the more electric aircraft. – © Liebherr

Landing gear surface

Aircraft components are subjected to extreme stresses from their environment over long periods of time. The surface treatment gives them the properties necessary to withstand these stresses. Shot blasting is one of the most important steps in this process. Every minute, 11 million small steel balls with a diameter of 0.2 to 0.6 mm are accelerated with compressed air and projected onto the surface of the components in a targeted manner at 50 m/s (180 km/ h). When the shot reaches the surface of the components, the latter is condensed by the kinetic energy released, which increases their lifespan. Here, a Liebherr-Aerospace Lindenberg specialist inspects a surface-treated landing gear housing in a blast cabinet. – © Liebherr

Anechoic chamber

In the Liebherr anechoic chamber located in Toulouse, a regional aircraft air conditioning package is being prepared for acoustic testing. This room, 7.5 m long, 7.5 m wide and 8 m high, is unique in Europe. Here Liebherr can measure the noise emissions of its air systems under real conditions. Objective: to minimize the noise level, and thus improve comfort on board. – © Liebherr

altitude box

In an altitude chamber, the components are subjected to atmospheric pressure simulating a flight altitude of more than 18,000 m and to temperatures between -55°C and +250°C. Extremely harsh cumulative conditions for the systems. The Liebherr-Aerospace Toulouse team thus collects very valuable data which informs it about the behavior and resistance of the equipment in the presence of extreme situations. – © Liebherr
