Under the theme “Transform.Develop.Sustain.” Liebherr-Aerospace is set to showcase its cutting-edge advancements at the Farnborough International Airshow 2024. The company is addressing the aviation industry’s pressing challenges through significant investments in research and technology, focusing on electrification, 3D printing, and hydrogen solutions. Liebherr is committed to enhancing the sustainability and efficiency of air transport, paving the way for a greener future.
Long wingspan for improved aerodynamics with folding mechanism
Innovative designs of thinner and longer wings support more CO2-efficient flying by improved aerodynamics. Liebherr is supporting this trend by offering reliable folding mechanisms for future more efficient aircraft platforms. An example is the Boeing 777X’s folding wingtip, which “beckons” visitors to the Liebherr booth. The moving mock-up (scale 1:1.15) shows how the wingtip of the extra-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 designed by Liebherr and will be on display.
3D Printing and Digitization
Liebherr’s cutting-edge 3D printing capabilities are already in use, with additively manufactured components flying daily. On display at Farnborough International Airshow is an additively manufactured housing of a secondary locking actuator. According to in-depth tests, the aviation-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.
Electrification and Decarbonization
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) and a hologram of the high-efficiency power pack (HEPP), are on display.
Leader in the development of electromechanical actuators
As electrification moves on in aviation, Liebherr has further added small electromechanical actuators to its product portfolio. The new concept specifically addresses the quickly emerging AAM (Advanced Air Mobility) sector. It is also essential for smaller aircraft, business jets, and helicopters. Liebherr’s product approach offers scalability for small installation envelopes, a favorable power-to-weight ratio, and high reliability.
Liebherr-Aerospace will present its extensive capabilities from July 22 to 26 in Hall 4, Booth 4918. Highlights will include innovative solutions for local hydraulic supply, modular electromechanical drives, and compressors for fuel cell technology aimed at onboard energy supply.
