Chinese Engine Development

Very interesting. The author appears to have been tracking the development of WS-10 for a long time.

I posted a year ago before the Zhuhai Airshow 2020 (held in 2021 though) that WS-10C thrust is at 155 kN, close to the original target for WS-15, although currently WS-15 itself had achieved thrust level of over 18t. That was from a different source. A couple of more respected members questioned this thrust level, believing that 144 kN is more likely.

This article suggests that WS-10B's thrust to be 144 kN while that of WS-10C is much higher, albeit at the cost of shorter engine life. So it's still likely that WS-10C has a thrust of 155 kN.

Of course, all these are speculative, backed-up by some indirect evidence and reasoning.
Yeah I’m not sure what to believe at this point.

nope.

this is the biggest misconception regarding CJ-1000A components. this news appeared in 2011-12, they were planning to collaborate with western firms for core components but project didn't materialized. i tell you the history and you will understand.

CJ-1000 name appeared = 2009

CJ-1000 team planning to collaborate with western firms for components = 2011-12

but deal didn't go through. after 4 years of planning and research, COMAC found AECC in 2016 and engine project officially approved in 2017. core machine ignited and first porotype appeared in 2018. all major components produced by Chinese firms/institutes.

the time period between 2012-2018 was basically for time given to major Chinese suppliers. compressor , combustion chamber , turbine each and every major component produced in mainland by Chinese origin firms and some universities involved too

46 major suppliers are involved in CJ-1000 engine and all are based in mainland. same suppliers are providing the parts to CJ-2000 engine.

i know the name of each and every firm/institute and even the names of team leader LOOL. but can't post the details. sorry
If you have insider knowledge on Chinese engine development, do you have any particular details about specs or component technologies related to the WS-15? I’m curious what you think or may know about things like how many stages its high pressure compressor will have or what the pressure ratio of the HPC will be, what kinds of materials it uses for different sections or stages of the engine, etc.

We probably won't know the precise figures for a long time.

But we can be pretty sure that China has come a very long way in military aircraft engines. The progress is across the board and foundational. That is, they have made strides in design, materials and gained tremendous operating experiences, given how many WS-10s have been produced and in service by now. A lot of things about aircraft engines are still empirical and experience-based. As the article said, Taihang or WS-10 has been 40 years under development and iterations. I still recall that sense of hopelessness about WS-10 and Chinese aircraft engines in general back around 2010. It feels quite differently these days.

So, even if much of the article is speculative and based on indirect evidence, the trajectory of the development is more or less credible.

Even the tone from Western msm is different now, WS10 is now regarded aa a peer instead of a ridiculed product.

CCTV once revealed the thrust of ws-10b, that figure i believe is credible (Dry thrust : ~90kN, After-burner: 144 kN).

That is Shenzhen TV not CCTV.

The voice at 3:36 is by the news anchor WITHOUT PLAAF speaker's (Shen Jinke) voice with subtitle (as at 1:00). In other words, it is not what PLAAF saying, nor CCTV saying.

Also it looks strange that the voice is NOT integral part of the footage but added afterwards, you can see that half second delay between the lips movement and the voice.

I personally have seen 144kN long time ago on a placard, I don't doubt much about it. But the video clip as a proof is very suspicious.

Well, it's shared by PLAAF account.

That is true. Just like in the past two or three years we have seen 81's weibo account (MoD) using American weapons talking about PLA systems. That track record tells me that social media account affiliated to PLA is primarily social media (operated by civilian contractors) not official which to me means an active officer of the right rank and branch speaking in front camera of CCTV1 or AVIC putting up a spec. It is the same as not all CCTV channels or state owned newspapers are seriously official.

You can't generalize all of them just because 81 acc was trash.
