Liebherr-Aerospace delivers first bleed air system for the C919 engine test bench

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, 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 be used for test-driven development of the engine LEAP 1C by CFM.

These components were designed to withstand thermal and mechanical requirements of the new-generation engine.

Measuring equipment has been fitted on the parts to provide COMAC and Liebherr-Aerospace with 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.
