1. Economically, C9 19 can make China civil aviation no longer rely on Boeing and Airbus mid-level trunk passenger planes imported from Europe and America, break the monopoly of European and American aviation giants, and save a lot of foreign exchange for the country.
2. militarily, due to the overweight fuselage, the maximum takeoff weight is 200 tons, which is not suitable for being converted into a special aircraft. There is great potential to refit large military special aircraft such as early warning aircraft and high-tech aircraft with C9 19. Although the probability that C9 19 will be converted into a military fighter is very small at present, it is not completely impossible for C9 19 to be used for both military and civilian purposes after China fully grasps all the technologies of C9 19 and can realize the localization of 100%.
3. From the perspective of social benefits, C9 19 project can promote the development of upstream and downstream industries, increase a large number of high-income jobs and stimulate local economic development.
4. In terms of technology, C9 19 can cultivate the design and manufacturing capability of China aviation industry in trunk passenger aircraft, train a group of aviation talents and improve the level of China civil aviation industry. In addition, the R&D and manufacturing of C9 19 aircraft have formed civil aviation industrial clusters in Shenyang, Chengdu, Xi, Shanghai and Nanchang, which not only promoted the local economic development, but also laid a solid foundation for the future R&D and domestic aircraft manufacturing.
Extended information 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 acronym of China and COMAC, and the abbreviation of Comac of 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.
