Why not use domestic engine c9 19?

C9 19 engine doesn't need to be made in China, because China doesn't have the ability to produce engines suitable for civil large passenger aircraft.

Because China does not have the ability to produce engines suitable for civil large passenger aircraft, and the engines of international civil aircraft manufacturers are also purchased from suppliers. By the end of 2023, international civil aviation engine manufacturers mainly include GM and Pratt & Whitney in the United States, Snecma in France, and IAE and CFMI in transnational cooperation. Of course, it is best to use engines from China, but the development of civil aviation engine industry can only be driven by large aircraft.

Without a big plane, there would be no demand and no platform. This is the relationship between the industry leader and the industrial chain. The c9 19 engine is made in America. As the "flower of aviation", aero-engine can be said to be a complete experience accumulated by aviation technology and industry. The engine of C9 19 is LEAP-X 1C engine.

LEAP-X 1C engine is a large jet engine developed by CFM International, a large passenger aircraft engine manufacturer jointly established by General Electric Company of the United States and Snecma Company of France with a capital ratio of 50% each. 18 carbon fiber composite fan blades developed by Safran Company and ceramic-based composite turbine components developed by General Electric Company of the United States are adopted.
