The article is written by People's Daily, a state-controlled news organization, so of course it will say the WS-10x is good. Without a free and independent Press, we can't take such stories at face value.First posted by Broadsword at CDF. I know you are here under different handle name.
I don't know why the Russian has been bad mouthing WS10 engine for awhile. Concocting outlandish BS.They think they can get a way doing it, since China normally doesn't respond to this kind of BS. Not this time though they retort back. I think People daily got their number wrong 2005 when Taihang was certified for 300 hr I believe. It start production in 2010. I think he is right western engine has better lifespan and MTBO and better efficiency
Taihang engines do not pose safety hazard: experts

Chinese experts have denounced speculation by foreign media that the country’s best warplane engine may pose safety risks.
“Judging by the performance and application of the WS-10A Taihang engine, it’s unlikely that potential hazards such as explosions will occur during flight. If such safety loopholes do exist, the government will definitely recall the engines without risking the lives of pilots,” a military expert from the National University of Defense Technology told Science and Technology Daily in an interview.
The expert, Wang Qun, made his remarks after a Russian news website accused the WS-10A Taihang engine of being a copy of Russia’s AL-31F. According to the report, China tried to raise the engine’s operating temperature to 50 degrees Celsius, but due to its inability to produce complex single-crystal blades, the engine could explode at any time during flight.
“There is a moon-to-earth distance between Taihang and the AL-31F,” read the report. Wang, however, disagreed.
“It’s true that China’s engine technologies lag behind those of its Western counterparts, but it’s not objective to belittle Taihang’s performance. Thaihang’s disadvantages lie in its lifespan, reliability and stability; otherwise, the gap between Taihang and more advanced engines is not that big,” said Wang.
“Conservatively speaking, China reached the level of developed countries in the '90s, as far as engine manufacturing goes. The country has already made great achievements, and will soon catch up to its Western counterparts,” Wang added.
First launched in 2005, Taihang engines have been deployed by the People’s Liberation Army Air Force in five air force regiments. Various fighter jets are also equipped with the engine, including the J-11B and J-15 carrier-based fighter jets. So far, there have been no crashes due to engine failure among fighter jets equipped with Taihang engines.
It's less saying WS-10 is "good" so much as directly refuting foreign media saying it's "bad".
And actually I think we can take some of its claims at face value -- Chinese state media do not often give out clear cut statements that often especially for technology or engineering matters and even more rarely for military matters, but when they do there's often a significant component of truth in them.
That is why state media reports are often placed very high on the totem pole in terms of reliability for informing us PLA watchers, because Chinese state media don't really mess around when they report on military related technical matters especially if they're citing a direct expert in the field that's judged to be reliable themselves.
So please don't come in with that "state media = unreliable" nonsense, because if you've been paying attention in the last few years here, Chinese state media is one of the must fundamental sources for the China defence watching purposes of this forum.
edit: and of course if anything doesn't jive, then some simple critical thinking often solves the problem too...

As you say the proof is in the pudding. Read my lips NO CRASH ACCIDENT! sofar. That is the best proof you can get . And 400 specimen has been flying since 2011.
We see it installed on new J16 even J15 and they keep churning out those plane That is vote of confidence!

Yeah but we also hear that half of them are in constant repair so....
Where did you hear that?
Are you talking about readiness rate? (which leads to the same question -- where did you hear that?)
I don't think there were 400 installed or in service WS-10s in 2011, maybe by 2014.
There should definitely be that many by now.

That was true prior to 2010 but is it still the case? The fact that the PLAN uses the land-based J-11BH/BSH tells us that reliability has improved considerably. The hurdle remaining for the WS-10 series now is the carrier-borne J-15 and J-10 variants. J-15T and J-10B are testing WS-10 versions, so time will tell how successful they are.
I'm not even sure if it was true in 2010.
We knew that the first batch/regiment of J-11Bs used Al-31Fs because at the time WS-10s weren't ready enough, and we also had pictures of J-11Bs at the factory without engines waiting for WS-10s to arrive to fit them.
But I was never aware of in service WS-10 equipped J-11Bs (or any WS-10 SAC equipped flankers for that matter) ever having "half" of a unit or even the full fleet "in constant repair". They either had WS-10s in regular service (without any issues heard) or they had Al-31s (for first batch J-11Bs) or that batch which had yet to have engines.
I'd like SamuraiBlue to demonstrate where his claim is from, because such an ambitious statement like that cannot really be thrown around here without some serious reliable source backing it up.
Since when did freedom and independence equal truthfulness? I'm a free and independent person, if I told you the Taihang is better than the F135, would you believe me? Plenty of free and independent persons and entities lie, because everyone has an agenda, and it ain't cheap running a news organization.
