SHANGHAI – China’s self-developed demonstrator aircraft engine CJ-1000AX has completed a successful test run in Shanghai, the engine maker said Sunday.

AECC Commercial Aircraft Engine Co. Ltd. (ACAE) designed CJ-1000AX for China’s homemade large C919 passenger jet, developed to rival global leading airliners such as Airbus A320 and Boeing B737.

The engine reached a rotational speed of up to 6,600 revolutions per minute in the test run, ACAE said.

The company inked a deal with Commercial Aircraft Corporation of China, the maker of the C919 jetliner, on developing its engine system in December 2016, and completed assembling CJ-1000AX in December, 2017.

ACAE has more than 110 global and domestic partners in commercial aircraft engine industry.
