Note: CFM International Company is a large-scale passenger aircraft engine manufacturer jointly established by General Electric of the United States and Snecma of France (Safran Group), and the capital ratio of both parties is 50%. In February, 2009, Comac of China selected LEAP- 1C engine as the only western-made engine of 150 C9 19 aircraft. At the same time, Comac China and CFM International will jointly set up a LEAP- 1C aircraft engine assembly and commissioning production line in China for assembling C9 19.
Extended data
C9 19 large passenger plane, full name COMAC? C9 19, the first trunk civil aircraft in China with independent intellectual property rights according to the latest international airworthiness standards, was developed in 2008. C is the initials of China and COMAC, and the abbreviation of Comac in China. The meaning of the first "9" is eternal, and "19" represents the maximum passenger capacity of China's first medium-sized passenger plane 190.
C9 19 large passenger aircraft is a large jet civil aircraft with independent intellectual property rights developed by China in accordance with international civil aviation regulations. It has 65438 seats +058- 168 seats with a voyage of 4075-5555 kilometers. 20 17 successfully made its first flight on may 5, and ended on February 26, 20 18. 201on February 6th, 2008, Commercial Aircraft Corporation of China announced the delivery of the first C9 19 single-aisle passenger plane 202 1.

(2) Design technology
1. Advanced aerodynamic design technologies such as advanced aerodynamic layout and a new generation of supercritical airfoils are adopted to achieve better cruise aerodynamic efficiency than similar aircraft in active service, and have cruise aerodynamic efficiency comparable to competitors in the aftermarket for ten years;
2. Adopt advanced engines to reduce fuel consumption, noise and emissions;
3. Adopt advanced structural design technology and a large proportion of advanced metal materials and composite materials to reduce the structural weight of the aircraft;
4. Adopt advanced fly-by-wire control and active control technology to improve the comprehensive performance of the aircraft and improve human factors and comfort;
5. Adopt advanced integrated avionics technology to reduce the burden on pilots, improve navigation performance and improve man-machine interface;
6. Adopt advanced cabin comprehensive design technology to improve cabin comfort;
7. Adopt advanced maintenance theories, technologies and methods to reduce maintenance costs.
Specific principle
1. owns completely independent intellectual property rights.
2. At the beginning of the project, purchase some foreign system equipment and encourage foreign suppliers to develop in China. Gradually form China's civil aircraft industry.
3. Meet international requirements in 2020 (such as pollution discharge and noise, etc.). ).
4. Ensure safety, highlight economy, improve reliability and comfort, and emphasize environmental protection.
5. Grasp and understand the needs of the market and customers, reduce resistance, reduce weight and reduce emissions, which is better than the competitive machine in an all-round way, and the direct use cost (DOC) is reduced by 65,438+00%.
6. Adopt international standards, focus on domestic sales and enter the international market.
7. Strengthen strategic cooperation. According to the "main supplier-supplier" model, we will deepen international and domestic cooperation, share risks and benefits, and form an international and domestic supplier system for large passenger aircraft.
