Fully Ceramic Composite Heat Exchanger Qualification For Advanced Combustion Chambers

In the continued development of hypersonic propulsion systems, within the frame of the A3CP (Advanced Composite Combustion Chamber) program, Snecma and Onera have jo intly developed and tested a light, fully leak-free, composite heat exchanger technology. This paper presents the last qualification steps performed. These include the implementation of a test sample in the Onera ATD5 scramjet test rig, for the performance of eight short duration Mach 7.5 test cycles, and the evaluation of another sample for longer duration tests.
