Domestic large aircraft C919 is about to collect evidence

At the first World Design Capital Conference in Shanghai on September 15th, Wu Guanghui, an academician of the Chinese Academy of Engineering and the C919 large passenger aircraft series chief designer, revealed that the Chinese COMAC has completed the test flight task before the C919 large aircraft obtaining evidence. Civil aviation device takes off and delivered to the first customer -China Oriental Airlines.

The C919 large passenger aircraft is China's self -developed and independent intellectual property rights. The short -range commercial trunk jet aircraft was successfully developed on May 5, 2017. On November 27, 2020, the first model inspection approval was obtained. At present, there are 28 customers in the C919 aircraft, with a total of 815 orders.

China Commercial Flying has suppliers worldwide, and has manufacturers in many domestic cities, but all design is concentrated in Shanghai. Wu Guanghui said, "The level of air dynamics design of civil aircraft directly determines the safety, comfort, economy, and environmental protection of the aircraft. We pay special attention to improving the level of pneumatic design of the C919 aircraft."

Traditional pneumatic design usually adopts air tests and calculations. During the development of the C919 aircraft, more than 20,000 wings and more than 2,000 wings were designed. Finally, 7 two -wheel turbine wings were selected for wind tunnel experiments, and the research and development cycle was greatly shortened through simulation simulation and other technical means.
