Liebherr-Aerospace & Transportation employs approximately 6,000 people worldwide, including 1,500 people in the Toulouse region, in five divisions: air systems, landing gear, flight controls, transmissions and on-board electronics. The company supplies core systems to most of the world’s major aviation programs such as Airbus, Boeing, COMAC, Dassault Aviation, Embraer, Leonardo Helicopters or Rolls-Royce.
The long-term vision of exclusively family ownership of the shares of the Liebherr Group enables Liebherr-Aerospace & Transportation to consistently and sustainably invest above industry averages both in its facilities and in research and development.
These investments provide Liebherr with the means of production, digital systems and technologies that enable it to make a significant contribution to the success of the aviation decarbonization initiative. Liebherr is a first-class partner for major aircraft and aero engine manufacturers and offers them a host of technologies they need to increase productivity and reduce carbon emissions, such as:
- Rolls-Royce’s Next Generation High Bypass UltraFan® Engine Power Reduction Unit
- The Boeing 777X wingtip deployment and locking system, the latest addition to the Boeing wide-body aircraft family.
- Air Compressor for Hydrogen Fuel Cells
- Airborne electronics cooling and power conversion systems that accelerate the deployment of more electric aircraft.
- Key Components of the Thales Alenia Space Payload Payload Cooling Loop

Aircraft components are subjected to extreme environmental stress for extended periods of time. The surface treatment gives them the properties needed to withstand these loads. 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 by compressed air and purposefully thrown onto the surface of the components at a speed of 50 m/s (180 km/h). When the shot reaches the surface of the parts, the latter are compacted by the released kinetic energy, which increases their service life. Here, a Liebherr-Aerospace Lindenberg specialist inspects the surface-treated chassis shroud in a shot blasting chamber. – © Liebherr
In the Liebherr anechoic chamber located in Toulouse, the air-conditioning kit for regional jets is being prepared for acoustic testing. This hall, 7.5 m long, 7.5 m wide and 8 m high, has no analogues in Europe. Here Liebherr can measure the noise level of its air systems in real conditions. Challenge: Minimize noise levels and thus increase comfort on board. – © Liebherr
In the pressure chamber, the components are exposed to atmospheric pressure, simulating a flight altitude of more than 18,000 m, and temperatures from -55°C to +250°C. Extremely harsh cumulative conditions for systems. In this way, the Liebherr-Aerospace Toulouse team collects very valuable data that informs them about the behavior and stability of equipment in extreme situations. – © Liebherr
