The former Russian CR929 aircraft design team was disbanded. They are now working for Gazprom on a new regional airliner aircraft design.

Work on the composite wing for C929 and the PD-35 engine is still ongoing. Just this year they finished ground tests of the hot section of the PD-35 at temperature and pressure.

Too bad. I wonder if COMAC can hire some experienced Russians to do R&D. You never know what key knowledge open may bring.

do you want me to give an honest answer ..

China basically squeeze enough Ukrainian aerospace industry and talent in last 30 years.. also after the collapse of USSR so many Russians joined Chinese industry as China offered lucrative deals ..

Chongqing/Shanghai have tons of those engineers. already settled in China.. there are bunch of former ANTONOV engineers currently working in China. and many stories i cannot tell here ... XD

China now itself grown into a giant researcher plus those foreign talent. so COMAC hardly need any assistance in R&D sector.

Tens of thousands? I doubt there are that many chinese aerospace engineers...We are talking about 5 digits here

@FriedRiceNSpice just gave random figure .. he didn't actually meant, thousands of engineers ..

but its true, there are so many Ukrainian aerospace talent currently working in China..

Ah I may have been off by a magnitude, possibly two :p

I yesterday just happened to come across this statistic on the number of Aerospace Engineers worldwide. China literally added 2 more zeros through the decades. Not sure how accurate the data is. It says China had around 100 A.E. during the 1970s.

Not surprising as aerospace engineers are employed in civilian airliners, manufacturers of aircraft, engines and components, military and reasearch institutes.

Chinese universities produce around 1.6 million STEM graduates each year.

Russia's inclusion in CR929 was basically Political strategy of COMAC and technological too.. both parties wanted to challenge Boeing/Airbus in wide body aircraft segment. Russia have strong political influence in Africa/Central Asia.

The delay occurred in this project mainly because of IP rights disputes.. but later on it has been sorted out but as we know, War interrupted again .. so COMAC decided to go alone due to various reasons..

Russia also offered Joint Engine venture for CR929. but COMAC declined and eventually decided to go alone again. so we have CJ-2000.

written agreement between both parties is still valid. but Russia's position have switched. Russia is providing composite wing to C929.. COMAC still consider Russia a valuable partner in this project ..

as per CEO's own statement, the experience we gained from C919 project is extremely valuable. based on this we can design and produce any type of civil aircraft.
--------------------------------------------------------------------------------------------------

PROGRESS in this project-

C929 wide body aircraft has entered in detailed design stage and Joint team from six different departments have assembled to review components/parts include propulsion..

C929 fuselage , mid fuselage , wing , tail , nose and landing gear contracts have awarded.. so far all are domestic suppliers. obvious Wing is from Russia..

Is the wing more complicated than other parts due to the flexibility?

Wing is no doubt one of the hardest part of Civil aircraft. for example, for C919 Chinese team designed more than 2,500 wings, and selected 2 of them to optimize the design..

for CR929, from the beginning, Russia took the responsibly of composite wing as they have more experience in this department. China took other parts responsibly such as composite wing , tail and nose and landing gear system.. Russia's MC-21 aircraft have composite wing.

China also working its own composite wing for C919/C929..

in 2019, The North Research Center of COMAC has done the full-scale box section test and verification of the T800-level composite wing of C919 ..
