Domestic aircraft, will be delivered soon!

Academician of the Chinese Academy of Engineering, the chief scientist of China Commercial Aircraft Co., Ltd. (referred to as "COMAC") Wu Guanghui, chief scientist and C919 large passenger aircraft chief designer, said in Shanghai on the 15th that the C919 large passenger plane completed the test flight before all evidence obtained on August 1, This year will soon obtain a flight certificate from the Civil Aviation (China Civil Aviation Administration) and be delivered to the first user Eastern Airlines.

On the same day, the first world design capital of the Shanghai Municipal People's Government opened in Shanghai.

According to Wu Guanghui, China Commercial Flying was established in Shanghai in 2008. In the past ten years, China Commercial Fly has developed a total of three products: ARJ21 line passenger planes, C919 large passenger planes, and CR929 long -range wide -body passenger aircraft.

The C919 large passenger aircraft is China's self -developed and independent intellectual property rights with independent intellectual property rights. It successfully flew on May 5, 2017. There are 28 customers, with a total of 815 orders. In 2022, strive to deliver the first passenger plane in 2022 Essence

The ARJ21 branch passenger planes have been delivered to 75, 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 a large domestic aircraft from a design perspective. He said that China Commercial Flying has a supplier around the world and has manufacturers in many domestic cities, but all its designs are in Shanghai.

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

Specifically, the simulation of air dynamics of large -scale passenger aircraft C919 needs to take advantage of the traditional supercomputing of 100 trillion levels. China COMAC and Huawei have created industrial -grade fluid simulation models- "Oriental Royal Wind" The R & D cycle is inserted "smart wings" for large planes.

"Applying artificial intelligence, we only spent the traditional supercomputes of 1/20 to 1/30," he said.
