in December 222, Comac China delivered a C919 large passenger plane to China Eastern Airlines.

this is a large jet civil aircraft independently developed by China and with independent intellectual property rights. The delivery of C919 indicates that China's civil aviation industry has made a major breakthrough in the field of independent research and development, and also injected new impetus into the development of China's aviation industry.

C919 passenger plane is the fifth generation fighter independently developed by China, and it is also an important milestone in China's civil aviation industry. The research and development of C919 has gone through a long period of research and test, including aerodynamics, material science, electronic equipment and other aspects. At the same time, the research and development of C919 has also been strongly supported by the government and cooperated by many domestic enterprises, including enterprises in aero-engines, avionics, materials and other fields.

The C919 passenger plane has the following technical characteristics:

1. Advanced aerodynamic design: The C919 adopts advanced aerodynamic design, including streamlined fuselage and supercritical airfoil, which makes the aircraft have higher flight efficiency and lower energy consumption.

2. Advanced material technology: The C919 adopts advanced material technology, including carbon fiber composite and aluminum alloy, which makes the aircraft have higher strength and lighter weight.

3. Advanced electronic equipment: The C919 adopts advanced electronic equipment, including advanced flight control system and autopilot system, which makes the aircraft have higher flight stability and safety.

4. Comfortable cabin environment: The cabin design of C919 pays attention to comfort and humanization, including spacious seats and advanced entertainment system, so as to provide passengers with a better flight experience.
