This indian tweeter claims that WS-15 and WS-19 will only have low production of 3-5 units per year to 2026

Can anyone verify the authenticity? And whether this plan is outdated or not?

You should have stopped reading after this.

I am curious . What comes after nickel superalloy for turbine blades in the hot section. Can SiC/SiC composites be used or else high entropy alloys have to be used. I only know a few materials . Would like an opinion from someone more knowledgeable? What other materials can be used ?

Can anyone answer my question.

you are posting 2019 tweet and we are in 2022. insane

how many times do i need to post. each and every tech related engines have mastered. now China marching towards cutting edge engine technology.

indians are jealous and delusional people. they cannot see the progress of China.

China’s re-emergence as a great power happened extremely fast. This is why outdated information about China is so widespread.

Bro after WS15 is there any new engine on the horizon? and can you identify each class and aircraft usage? thanks

They've been working on Ceramic Matrix Composites (CMC) for around 10 years I believe. Not alot of news on this front but I am aware of some major progress with successful development of a CMC turbine disc. This included the turbine and the blades. Supposedly there are unconfirmed rumours of later iterations of the CJ-1000A and AEF3500 turbofans will include CMC coatings in the turbine.

These are future engines so this is many years away. CMC engines probably won't be available until there is a J-20 6th generation successor. I fully expect the rumours of CMC turbine sheathing for the future versions of CJ-1000A and AEF3500 to come true much sooner, probably sometime in the first half of the 2030s, since those engines don't have the same temperature tolerances.

I'd say China's turbofan tech has been surprisingly impressive given they started much later with fewer resources, and a lower knowledge base (at the start). Already China is one of three nations to have high thrust turbofan. 3rd gen materials level vs the leading edge 5th gen materials. Almost all major leading engine tech and manufacturing tech have been mastered and done, except ceramic composite blades.

XBGY Advanced Ceramic Technology Corporation successfully developed and tested a ceramic matrix composite monolithic turbine disk a couple of months ago. This included the turbine and the turbine blades.

someone interpret this as doubling production of ws10 hence dramatic increase of j20 production

Maybe not doubling production exactly, but definitely in that direction. They are probably getting a lot more money from servicing and support of the ever larger WS-10 fleet. They have also started to supply WS-20s for Y-20s. But I think it's reasonable to assume that J-16 and J-20 production are up big time. J-10 production is probably down a little bit, but it only uses 1 engine.
