A folding wingtip for a Boeing 777X airliner is one of several innovations featured at Liebherr Aerospace’s Paris Air Show exhibit.

European aerospace group Liebherr is at the Paris Air Show demonstrating the latest examples of its decarbonization and digitization innovation across a wide array of aircraft systems. The company’s exhibit showcases breakthroughs in flight and environmental controls, thermal management and actuation systems, power electronics, and landing gear.

Arguably, the most eye-catching element on display is the folding wingtip that Liebherr’s engineers have developed for Boeing’s 777X widebody airliner to ensure that it can fit in and around crowded airport gates. The moving, sub-scale mockup on display this week demonstrates how the 777X’s long wingspan can be temporarily reduced for operational flexibility, and the group has been working on designs for thinner, longer wings that it says can reduce fuel burn.
