Why don't you add in J-10A in the mist too, since your sole purpose is to degrade the Chinese engine development? Oh... and let me help you some more, the J-20 and J-31 are also not using Chinese build engines. Okay, happy now? The Chinese engine development had hit a dead end and they can do nothing but to get engines from overseas.
Seriously man... you simply ignore the fact that J-11B which had by far a great number of machines flying... and these are using WS-10A. And I already stated time and again... but you simply choose to ignore those and keep bringing up the J-15...
J-15 prototype flew in 2009, at that time WS-10A are not ready yet. J-15 is an aircraft carrier borne fighter, and we all know that the engines needed in those fighters are different (at least criteria wise) and the WS-10A might not meet those requirement. That does not mean that WS-10A is not ready... it is just not for the J-15 yet.
J-10 is designed with one variant of the AF-31 engines, it is different from WS-10A so you cannot just take and plug the engine in... so... I really don't understand what is so difficult to understand... WS-10A is ready and had been used frontline fighter like J-11B. WS-10A might not be suitable for carrier borne fighters yet because of various reasons, for example - corrosion. And as pointed out by other members of the forum - J-16 is using WS-10A. J-10B is by Chengdu, and WS-10A engine is made by a subsidiary of SAC which so happen to be the manufacturer of J-11 series of fighter. And so if I was to run SAC, I will confirm fulfill my own companies requirement before attending to other companies' needs. Plus that need is not a simple thing, because I do need to make modification to the existing WS-10A before able to put it into the heart of J-10B/ J-10A/ J-10.
Are we going to suggest the F100 was a failure just because the F101 exists?
dont make this thread into russia vs china engine development. We all know that china is behind russia in terms of aircraft engine, and that is not surprising, since its a very specialized tech and requires a lot of resources to develop. russia has been developing turbofan engines since decades ago.
I just disputing the line that WS10A production has slowed down cause of the less need for it. more likely,they can't produce fast enough rather than the other way around.

Another possible scenario is WS-10A engines aren't very good, so the factories continue their use of Russian engines.

How would you explain those J-11B with W-10A? Does the PLAAF consider the J-11B inferior and is willing to put bad engines on them? Do we have any information on the status of those J-11B with the W-10A engines? Are they first-line units? If yes, then the PLAAF should think highly of these J-11Bs and would not out bad engines in them.
If the question we are asking is whether WS-10A is ready, we should first define what we mean by being "ready".
I think a fair definition is having WS-10As equipped en masse, where those equipped with it reach their requirements set by the PLAAF.
WS-10As are equipped on some 100 J-11Bs, meaning a 200 engine minimum production run, most likely well over 200 given need for spares and backups. These engines were produced over a 3-4 year period given we know when the first J-11Bs with WS-10As entered service and how many regiments of J-11Bs were ultimately produced, along with margins of error for other flanker regiments equipped with J-11BSs that also use WS-10As. With no reason to belive that WS-10A J-11Bs have any performance limitations compared to Al-31 equipped J-11Bs, and given its decent production run, I consider WS-10A to be "ready".
The fact that WS-10As are not equipped on J-10Bs, on J-15s or J-20 at this moment does not mean WS-10A is not equipped en masse because 200 engines on 100 fighters is already a good number. It just means it may not reach the specific performance requirements for those fighters (or other requirements) but does reach it for J-11B.
So another question we can ask, is whether it is reasonable to expect WS-10A to equip all those fighters listed above to consider it "ready," when it is already equipped en masse on J-11B.
And I don't know why first operational J-20s using indigenous engines or not is a litmus test of the overall state of the chinese industry. A very arbitary metric, really.
