If he is such lousy and WS-10 is that bad. I am sure he will not get the national award in 2008. Come on, CCP don't reward useless fella. Where did you heard the urban legend from?

WS10 has powered 5 Regiments of J11B, thats 24 per Regiment with two engines each totals 240 engines
J15, J10B and J16 are using WS10, and I don't think there has been a single incident involving WS10 so it means they must be doing something right
In the last few years China has been pouring man and $$$ into engine programmes and they are starting to see results, nothing happens over night

Or not a sign at all? No news is neither good news or bad news. It is no news.
It has been couple yrs already. let's say another 10 yrs and still no news, do u think that's good or bad?

Well, the latest photos showing J-15 aboard the Liaoning and the J-10B in yellow skin powered by AL-31F proves that WS10 series are not mature enough. Time to go!
Except it hasn't been another 10 years. Does no one remember what the original estimates for both the J-20 and WS-15 were? Just because the J-20 happened ahead of the predicted schedule doesn't mean everything related to the program will. I'll start wondering about the WS-15 when things start deviating from original timeline projections and we still see no news by 2015, but it's just a tad early to insist there must be something wrong.
Jet engines by the nature of their development process are less transparent and harder to leak than airframes. There's no airframe exposed to cameras while conducting test. When the engine is ready it's ready. It's stuck into the butt of a plane, and we'll see it in its ready complete and fully tested form.

WS-10A is not mature enough for single engine fighter like J-10B, and carrier based fighter like J-15. This does NOT mean that it is not mature enough for J-11B, which have over 120 in PLAAF right now.
The rumor says that by 2014, the newly improved WS-10B with FADEC, 135KN of thrusts and much improved realiability will enter mass production to power the J-16, J-15, and even J-10B.
So lets just wait and see.
I think as of now WS10A is inferior to AL-31F. They say WS10A has longer life expectancy than AL-31F.
But I think the critical issue is the new WS10A has enough percentage of them completely stall or die in mid air.
That's they won't risk it on J10B and J15.
Now people are saying they have upgrade on WS10B and WS15. Who's to say when the real production come and they won't see the same again, the new installed engine with enough percentage of them die in mid air.
I think that's real issue. It's not about wear and tear and life expectancy or anything like that.
Ws10A is less reliable than AL-31F and WS10B , WS15 could also have same issues.
It's a Production issue.
I think China should stuff their WS10A on UAV, Trainer jet to test the heck out it, if stalled in mid air, just eject and dump the planes. The hurdle hasn't overcome yet. Big deployment and more real testing are needed.
I would rather see China completely surmount the engine issue than seeing J20, J31 and HK6 flying. Those are fools golds.
I rather see WS13 powered JF-17 fighters exporting in large quantity throughout the world and J15 powered by WS10A enter full production rate. WS19 powered transport plane. That's more meaningful.

1) Evidence that a significant amount of them stall?
2) Reliability of a design is not static. All designs get more reliable over time as more data is collected and problems debugged. This includes general problems that arise from the production process.
3) Newer designs benefit from the problems encountered in early ones. There's no guarantee the ws-15 will face the same issues either in design or in production because over time China's industrial knowledge can only improve.
