Liebherr-Aerospace a major supplier to the international aviation industry will participate at the 54th Paris Air Show in Le Bourget, under the motto “transform.develop.sustain.”
The company will display will its latest innovations such as electric air conditioning systems, modular electro-mechanical actuators, solutions for local, decentralized hydraulic supply or fuel cell technology for on-board energy supply.
Under the motto “transform.develop.sustain.”, Liebherr-Aerospace’s presence at this year’s trade show demonstrates that the company has accepted the challenges and is ready for these industry transformations. With investments in research and technology far above the industry average, Liebherr is making a significant contribution to the development of efficient and environmentally friendly air transport.
Many years of experience in the design and integration of air management, flight control and actuation systems, landing gears and in the field of signal and power electronics make Liebherr an indispensable partner to aircraft manufacturers. Based on its core competencies, however, Liebherr is looking beyond the limits of what is feasible today. Electrification, 3D printing or hydrogen technologies can make a huge contribution here.
Long wingspan with folding mechanism for improved aerodynamics
Even from a distance, the Boeing 777X’s folding wingtip “beckons” visitors to the Liebherr booth. The moving mock-up (scale 1:1.5) shows how the wingtip of the long wing can be folded upward to better fit the airport infrastructure. Components of the mechanism, such as the angle gearbox, the power drive unit and numerous actuators, are from Liebherr and will be on display at the booth. Innovative designs of thinner and longer wings support more CO2-efficient flying. Liebherr offers reliable folding mechanisms for future more efficient aircraft platforms.
Leader in the development of electromechanical actuators
Liebherr-Aerospace has always been a leader in the research and development of electromechanical actuators (EMA) for medium to large commercial aircraft. Now the company is also adding smaller actuators to its portfolio.
The new concept specifically addresses the emerging AAM (Advanced Air Mobility) sector and also covers smaller aircraft, business jets and helicopters. Liebherr’s EMA family concept benefits from the experience gained from millions of flight hours in numerous aircraft programs with actuators and associated electronics over the past decades.
The development approach offers scalability for small installation spaces, a favorable power-to-weight ratio and high reliability.
Positioned for the future with electrification and decarbonization
Liebherr has also been driving forward the electrification of today’s aircraft for many years and also offers successful applications for the future in this area. In aircraft that will be more electric in the future, the engine will be decoupled from onboard power consumers for increased efficiency. Electric power will replace bleed air or hydraulic systems and enable the introduction of electric air management and actuation systems. Liebherr’s exhibits show that the company can already master these requirements today: Electromechanical actuators (EMA), the high-efficiency power pack (HEPP), the electric motor pump (EMP system) and the electric air-conditioning system (eECS), among others, are on display.
Furthermore, future more sustainable aircraft will require autonomous electrical power generation. Liebherr is working to ensure that hydrogen technology can be used to power elemental, non-propulsion electrical systems on board future aircraft using fuel cells. At the same time, thermal management of the whole, i.e. fuel cells and electrical systems, is being ensured.
3D printing and digitization expand possibilities
3D printing in aerospace is no longer a dream of the future. 3D-printed components from Liebherr are already flying every day. The company is constantly developing its capabilities and extending them to towards multiple applications. On display at the Paris Air Show is the additively manufactured housing of a secondary locking actuator. According to in-depth tests, the aerospace-certified housing is of lower weight, and its performance is 100% equivalent to that of a conventionally manufactured component.
In addition, digital means are revolutionizing the way Liebherr designs, builds and maintains aircraft systems. On its way to becoming a model-based company, Liebherr is exchanging models with customers as early as possible to contribute to more efficient aircraft design and development. With the help of special glasses, trade show visitors can get an impression of a Liebherr landing gear using an augmented reality application.
