How much confidence would you guys give to the success of this project? I kind of thought it would mostly be stalled considering the state of Russian defence programs in the past few years. Though their civilian sector looks a bit better. The MC-21 seems decent, even using composite wings

The PD-35 engine seems to be the most worrying, considering how ambitious it is. It seems like the Russian government is serious though, allocating hundreds of millions for it and I do hope it succeeds so there will be a non-western option for long haul planes.

Honestly feel it was a mistake for China to do a co-operative agreement. Russia is now behind China on most areas except engines, but even there China will soon catch up. Russians want to locate as much R&D and value-addition domestically (for understandable reasons) but this also slows the project down. China should have gone at it on their own.

It is not just the engines. Russia is also going to make the carbon composite wing. Right now only Russia has this technology to make carbon composite wings out of an autoclave.

It’s not that only Russia has the technology it’s that only Russia is doing it. They had to get outside help on it from a number of firms out of Russia.
Lockheed Martin made use of it in the X55 a number of years ago. It’s just that the Industry as a whole has chosen not to embrace it yet.

Would that be because it doesn't really offer anything significant over more conventional wings or because only Russia mastered the commercialising of the technology from a manufacturing for airliners pov.

This project is already failed for me. Even if it ends up flying and sells 200, it is a one plane project. To be really successful it should have transformed into an Asian Airbus.

Yes I am sure China can ask Lockheed Martin for the technology instead. :rolleyes:

Neither at this point. Neither as the MC21 is the first to implement it for production yet it isn’t in production. In theory it should be cheaper and lighter. But to say the Russians mastered it is I think a misstatement.
One of the firms they consulted with was Diamond Aviation which is a Chinese owned firm.

Really….
Aviation industry is very conservative in the airliner industry. your claim was that “ONLY Russia has this technology to make carbon composite wings out of an autoclave.” My point is that’s not true as written first. Second that Russia who is just starting with it themselves had to consult to get the technology.

Interesting. Well perhaps the Russians are aiming to complete it with this CR929 project if it isn't mastered yet. After all if and when MC21 and CR929 are completed projects, this technology is also completed for commercialization and associated manufacturing. It would be at a level far above what Lockheed Martin has delivered seeing as the LM's venture into this is limited to a one off experimental plane compared to the Rostec doing it for a production commercial airliner.
