First bleed air system for the C919 engine test bench delivered

After having been selected to develop, manufacture, qualify and certify the integrated air management system for the C919 single-aisle aircraft in 2010, Liebherr-Aerospace recently delivered the first bleed air system to Chinese aircraft manufacturer COMAC.

The system consists of bleed valves, a pre-cooler, a heat exchanger, high-pressure ducting and corresponding pressure and temperature sensors, which are connected with a bleed monitoring controller. It will be used for the test-driven development of the engine LEAP 1C manufactured by CFM.

Measuring equipment has been fitted on these components, which were designed to withstand thermal and mechanical requirements of the new-generation engine. Thus, COMAC and Liebherr-Aerospace will receive information on the behavior of the bleed air system during the engine tests.

The next step for Liebherr-Aerospace will be the delivery of additional components for the engine ground and vibration test benches to prepare the flight test campaign of the C919.

Liebherr-Aerospace supplies the air management system and the landing gear system for the C919.
