Is the C919 engine domestically produced?
2 Answers
C919 engine is not domestically produced; it uses the first CFM LEAP-1C engine from CFM International. Below is relevant information about the C919 engine: 1. Numbering meaning: C stands for China; 9 represents longevity; 19 represents a maximum passenger capacity of 190 seats. 2. Record: Before its first flight, it had already received 570 orders from domestic and international markets. As long as the first flight and production go smoothly, it is definitely a profitable deal. 3. Structure: According to the C919 airframe structure decomposition diagram, AVIC undertook the main manufacturing tasks of the major components of the C919 aircraft. For example, the nose is manufactured by Chengfei Company, the front fuselage and mid-rear fuselage by Hongdu Group, the wings by Xifei Company, the rear fuselage and vertical tail by Shenfei Company, and the front and main landing gear doors by Hafei Company.
As someone who has long been following the aviation industry, I understand that the C919 currently uses the LEAP-1C engine from the US-French joint venture CFM, which is not purely domestically produced. However, core components such as the engine nacelle and thrust reverser are manufactured by domestic companies. The domestically developed Yangtze CJ-1000A engine is currently undergoing testing and is expected to complete airworthiness certification by 2024. According to recent airshow materials, the core engine of the domestic engine has achieved 100% independent design, with high-pressure turbine blades utilizing third-generation single-crystal materials, and its overall performance is approaching international advanced levels. The replacement cycle for civil aviation engines is typically around 10 years, and in the future, we will see more domestically produced wings soaring in the blue sky.
