A half-scale metal model of China's first jumbo jet engine, the CJ-1000A independently developed by the Aviation Industry Corporation of China (AVIC), made its public debut at the 14th China International Aviation Exposition in the China National Convention Center from Sept. 21 to Sept. 24 and became the focus of attention at the exposition.

A head of AVIC Commercial Aircraft Engine Co., Ltd. (ACAE) announced on Sept. 21 that the large aircraft engine CJ-1000A is the first high bypass ratio turbofan engine for civilian use in China. Its core engine test is expected to be finished in 2014, and its experimental engine will meet the performance standards by 2016. This engine is scheduled to get a airworthiness certificate and realize product delivery in 2020.

Commercial aircraft engines are known as the jewel in the crown of the airline industry because of the great technology difficulty, high risk, huge investment and long development cycle. ACAE, general contractor of China's large aircraft engine project, was founded on Jan. 18, 2009 in Shanghai, which marked the start of the development of China's large aircraft engine.

Besides the open model of a C919 jumbo jet's passenger cabin, ACAE also use 3D cinema technology to present the appearance, performance index and the design concept of this domestic airliner, which has become one of the highlights of the event.

"The C919 jumbo jet is about to enter the project development stage and is expected to be reviewed at the end of this year." Said Tian Min, the chief accountant of ACAE, "The total number of C919 jumbo jet orders from home and abroad will surpass 50."

The C919 project is a good platform on which Chinese and foreign enterprises cooperated with each other to gain mutual benefit.

"We hope to provide the best products through association between strong enterprises rather than exchanging market for technology," said Wu Guanghui, the general designer of Chinese jumbo jet and deputy general manager of ACAE.
