Liebherr-Aerospace has been selected by Parker Aerospace based in Irvine, California (USA) to design, develop, produce and service the air supply subsystem for the fuel tank inerting system (FTIS) for the Airbus A321 XLR program. The FTIS decreases the probability of combustion of the fuel in the fuel tanks on board an aircraft. The air supply subsystem's purpose is to supply air at the required pressure and temperature to enable the optimised operation of the inert gas generation membrane.

The subsystem will be based on compact, lightweight, highly reliable components. It will be designed and produced at Liebherr-Aerospace Toulouse SAS, Toulouse (France), Liebherr's centre of excellence for aerospace air management systems.

The company builds upon a wide experience of air supply subsystems for the FTIS of the Airbus A320 family and the A330 family, together with a wide array of other aircraft programs like Embraer's E-Jet E2, and COMAC's C919.

Liebherr leverages unique experience in pneumatic components across most of the commercial aircraft programs that entered service over the last two decades: pneumatic valves, heat exchangers, compressors and turbines and associated controls, that are employed in engine pneumatics, engine bleed air systems, air conditioning systems or fuel tank inerting systems.
