It seems CFM has invested more into China than we at PW offered (I was part of one of the teams for PW 1000G offer).

Good for you, seems to be better choice for Chinese industry. I assume hot section is imported and cold section is produced locally and they are assembled/tested/verified in China for CFM LEAP? Do we have any more pictures/videos/information of this facility?

It is CJ-1000AX, not CFM-LEAP.

Product Introduction:
ACAE launched the R&D of engine for the C919 in the first place. At this stage, all the design works of demo engine has been completed, and ACAE started the trial-manufacture and tests for the components. The engine is scheduled to enter into service by 2025.
The engine is a high bypass ratio turbofan engine directly driven by two shafts. It consists of one stage fan, three-stage booster, ten-stage HPC, full annular combustor, two-stage HPT and seven-stage LPT. The technologies such as 3D aerodynamic design, lean pre-mix combustion, active clearance control, etc. and the new material technologies applied on wide-chord hollow fan blade, blisk, new generation single crystal blade, powder metallurgy parts, all together produce a high efficiency engine of lower fuel consumption, lower emission, less noise, and at same time higher reliability, longer life and better maintainability.

Sino-Russian CR929 program enters preliminary design phase

People's Daily Online Editor: Li Yan

Chinese and Russian authorities have approved the joint review of the widebody long-haul airliner dubbed CR929, noting that the program has now entered preliminary design phase.

"The Sino-Russian designed widebody long-haul airliner has been officially named the CR929, while the China-Russian Commercial Aircraft International Corporation has officially commenced operations," Zhao Yuerang, chief manager of China's state-owned aerospace manufacturer Comac was quoted as saying by Thepaper.cn on Thursday.

According to Thepaper.cn, the CR929 program will go through several stages, including project approval, joint review, preliminary design, manufacturing and final marketing. The program is now entering the preliminary design phase and is expected to produce the airplane within ten years.

Arguably the world's only new wide-body, two-aisle passenger jet to be manufactured by an entity other than Boeing and Airbus, the CR929 external design was unearthed in 2016, after Russian aerospace company United Aircraft Corporation signed a contract with China's Comac for designing a wide-body plane, challenging the traditional conglomerates Boeing and Airbus, according to Russian Aviation Insider.
