As early as November 2, 215, the first aircraft of the C919 large passenger plane, which was developed in China for seven years, was officially rolled off the assembly line. The full name of C919 is COMAC C919. "COMAC" is the abbreviation of the English name of Commercial Aircraft Corporation of China (hereinafter referred to as China Commercial Aircraft Corporation). C is taken from the initials of China and COMAC of China, which means that it will form an "ABC" pattern with Airbus and Boeing. It shows that the passenger plane is the will of the country and the expectation of the people. The first "9" means everlasting, and "19" means the maximum passenger capacity is 19, so China's first domestic passenger plane was named C919.
what's the significance of China owning a domestic C919 passenger plane? Because a large passenger plane is a strategic commodity. Therefore, if a big country can't produce large passenger planes by itself, it means that it will lose the initiative at a critical moment and be subject to people at any time. At present, only the United States, Europe and Russia can produce large passenger planes. If China wants to become an independent country with extensive influence, it must develop its own large passenger aircraft.
the development and production of China C919 passenger plane is a landmark project to build an innovative country, with completely independent intellectual property rights. Aiming at the advanced aerodynamic layout, structural materials and airborne systems, the developers have planned 12 key technical problems, including the integrated design of aircraft engines, the control law design of fly-by-wire flight control systems, and active control technologies. Advanced materials have been widely used in domestic civil aircraft for the first time, and the third generation Al-Li alloy materials and advanced composite materials have reached 8.8% and 12% respectively in C919 airframe structure.
on may 5th, 217, China's new-generation jumbo jet C919 completed its first flight, which will be a great moment for China's manufacturing industry. There is a popular saying in China that "China can only export hundreds of millions of shirts for a Boeing plane", which shows that China is at the downstream of the world industrial chain. Now, part of China's low-end manufacturing industry is moving out, while China people are moving towards high-end manufacturing industry, able to produce large aircraft with independent intellectual property rights and win this "pearl in the industrial crown".
