Liebherr-Aerospace recently delivered the first bleed air system for the C919 narrowbody to Chinese aircraft manufacturer Comac, the Toulouse, France-based aerosystems supplier announced on Tuesday. Comac chose Liebherr-Aerospace to develop, manufacture, qualify and certify the C919’s integrated air management sytem in 2010.
The system, which consists of bleed valves, a pre-cooler, a heat exchanger, high-pressure ducting and corresponding pressure and temperature sensors connected with a bleed monitoring controller, will serve in test-driven development of the CFM LEAP-1C engine.
Engineers have fitted measuring equipment on the parts to provide Comac and Liebherr-Aerospace with information on the behavior of the bleed air system during the engine tests.
Liebherr-Aerospace next plans to deliver additional components for the engine ground and vibration test benches to prepare the for the C919’s flight test campaign.
