Chinese Engine Development

or it could be WS19. Is this located at Guizhou? that should help the backward province.

Yes. This could be a possibility albeit a distant one. No news of WS-19 for an year and half. But the WS-19 entering mass production means the engine Pic of WS-19, with bunch of young scientists at the foreground, undergoing fixed rig tests, signified an engine that passed the tests with flying colors rather than one which just initiated testing process.
Too optimistic but then the news was rosy too - highlighting the success of the program under the female scientist.It's been like two years?

I was wondering why exactly China needs to produce WS-13 (WS-13E). No aircraft in mass production in PRC uses WS-13, afaik.

They specifically said 3rd generation turbofan, so probably not WS-19. However, info from
CD claims that progress is smooth for WS-19, unlike WS-15.

Do the WS-19 and WS-15 teams communicate and share tech?

If that thing deino posted about the new turbine operating at 1990K is true, that's a 200K improvement. Should put WS15 a bit over F119 imo.

Not sure how reliable ...

it says "推算", which can be translated to "calculated estimation". So it is not known numbers, not measurement of real engine. If it is calculated by design engineers based on measurement of a test engine, it would be a reliable guess of the final spec. Otherwise, it is just a made-up by somebody.

Yeah it makes one wonder what will the production facility be used for. JF-17 uses Russian engines and AFAIK Pakistan has already made a deal with the Russians to purchase engines for the foreseeable future. The other exports are in minute quantities and it doesn't justify a new production facility. So is this for initial production FC-31s like the article speculates or what?

I don't see how they could other than maybe metallurgy. The designs of the two are completely different.

They could actually end up sharing a lot of component designs that are just scaled down.

For me this sounds very much like serial production start for the non-afterburning WS-13 for the GJ-11 and eventually the regular WS-13 for the J-35.

emmm, depends on which part of the engine you talked about.

copying the engine case design and control system, like FADEC is a yes
it takes a lot more work to scale up and down the bypass, but still very common
but it's almost impossible to just scale up and down the core engine without major design and material modification.

Guys. Please don't beat me up on this. But I'm really, really a novice on this. So I got some questions.

I know jet engines are complex machinery and it required a lot of tech. But it is 80 year old technology.

So Why is China having such a hard time producing engines?

They may not be able to produce to the advance western type of enginrs. But surly they can produce engines that are comparable to those engines that are flying planes with in the 70s and 80s?

I know these 70s and 80s type engine are not good enough compares with modern engines with metallurgy etc. But if it was good enough to power planes then. Why not now?

Sure, we would like faster and longer lasting engines, but if people refusing to sell it. There's not a lot China can do.

Appreciated in advance
