The CJ-1000A uses foreign parts guys. If China really gets isolated it has to rely on the WS-20.
I thought the CR929 is targeted for introduction 2028-29?
Who knows, the CJ-1000A might even eventually replace the WS-20 in the Y-20.
But its introduction date has been severely pushed back. This makes relying on that engine for future planning a fool's errand I think.
If it uses foreign parts that only compounds the problem as this would probably restrict its use on military aircraft.
Eh, do you really believe the CR929 estimated entry into service date? For what it's worth the Russians have conducted wind tunnel testing of the airframe, and are presently doing subscale component tests for the PD-35 engine using the PD-14 as a basis. The Russians are also currently building an engine test facility which will be able to test large scale engines like the PD-35 which should be ready in a year or two. Having recently built a modern engine test facility which will enable them to ramp up PD-14 engine tests as that is supposed to ramp up to mass production. China has built a center for the CR929 in Shanghai complete with building and everything. Supposedly the Russians are working on a similar site in Moscow. But just look at things. The Russians are still studying where they would build a factory for the wings. Because of the size of the wings they have basically given up on air transportation of them and will seemingly rely on sea transport. So the factory that would produce the wings needs to be near the ocean for sea transport, preferably on the Far East, for final integration in China. One of the places being studied to place the factory is Vladivostok. But the location isn't decided and construction on the plant hasn't started yet. There is no existing aircraft industry there. So you would need to build the facilities and move staff there. I doubt it will be done quickly. Some people might be willing to move though since a lot of Russian civilian aircraft manufacturing is in Siberia, just not near the coast. Most of the production of the wings is also supposed to be automated so they shouldn't need that many specialists. UAC is also in the middle of a major reorganization and that might delay things. They are merging the research and development centers for Sukhoi and MiG. Presumably also for the transporter business but the way they will do it is even more murky than for the military fighter side.
Do you think the partners for the CR929 can do this plane in 7-8 years? I doubt it. Well, only if it is to be done as a photo op similar to the Boeing "Dreamliner" launch where they paraded an empty shell. I doubt a flying prototype will be ready let alone they would finish the testing and be delivering it to customers.
