Liebherr-Aerospace Delivers First Bleed Air System for the C919 Engine Test Bench

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.
