Wu Guanghui: C919 will soon be delivered to the first user before the test flight is completed

　　China News Service, Shanghai, September 15 (Reporter Zheng Yingying) Wu Guanghui, academician of the Chinese Academy of Engineering, chief scientist of Commercial Aircraft Corporation of China (“COMAC”) and chief designer of the C919 large passenger aircraft, said in Shanghai on the 15th that the C919 large The passenger plane completed the test flight before all the certificates were obtained on August 1. This year, it will obtain the airworthiness certificate from the Civil Aviation Administration of China (Civil Aviation Administration of China) and deliver it to the first user, China Eastern Airlines.

　　On the same day, the first World Design Capital Conference hosted by the Shanghai Municipal People's Government opened in Shanghai.

　　Wu Guanghui introduced that COMAC was established in Shanghai in 2008. In the past ten years, COMAC has developed a total of three products: ARJ21 regional passenger aircraft, C919 large passenger aircraft and CR929 long-range wide-body passenger aircraft.

　　The C919 large passenger aircraft is a short-to-medium-haul commercial trunk jet aircraft developed by China and with independent intellectual property rights. It successfully made its maiden flight on May 5, 2017. It has 28 customers and a total of 815 orders. The first passenger aircraft will be delivered in 2022. .

　　A total of 75 ARJ21 regional airliners have been delivered, with a total of 616 orders, connecting 110 cities, opening 263 routes, operating safely for more than 165,000 hours, and transporting more than 5.3 million passengers.

　　Wu Guanghui also interpreted the domestic large aircraft from the design point of view.

He said that COMAC has global suppliers and manufacturers in many cities in China, but all its designs are in Shanghai.

　　He said that traditional design methods have been difficult to meet the future goals of domestic large aircraft. Artificial intelligence breaks through the boundaries of scientific computing and can help the new development of large aircraft.

　　Specifically, the simulation of the aerodynamics of the C919 large passenger aircraft requires the help of traditional supercomputing of petascale. COMAC and Huawei have created a large industrial-grade fluid simulation model - "Dongfang·Yufeng", which greatly shortens the R & D cycle, plug in "smart wings" for large aircraft.

　　"Applying artificial intelligence, we only spend 1/20 to 1/30 the time of traditional supercomputing." He said.
