It could also be the WS-12, there was talk a few weeks ago of a major JH-7 upgrade but I guess the WS-13 is a big priority for Guizhou Liyang since I haven't heard of any new RD-93 orders from Russia in awhile.

The problem is I'm not sure how they will test this. They basically put WS-10A on J-11Bs because they are not comfortable with a new engine on a single engine fighter jet. But they don't really have one for JF-17, so where are they going to test out the small problems on it? Anyhow, it will be interesting to follow.

I think the first possibility will be that Il-76 engine testbed ... and then there will we no other than to re-engine one of the early prototypes !

that's a good point. the mig29 was supposedly designed as twin engine because neither AL-131 nor RD-33 were considered safe enough. They both needed time to mature on twin engined fighters, eventually allowing J-10 and FC-1 to be born. China won't have this kind of opportunity to mature a replacement engine for FC-1.

I don't know how legitimate this is since some of the WS-10 designations seem to be new/different from other info posted in the past. Maybe the experts here can tell.

There was an article post this week by Jane's Defence Weekly that largely confirms the details behind this chart. A partial extract of the article is available on-line:

The full article also includes a couple of additional details. The J-13 fighter referred to in the chart is reportedly not the long-awaited, next generation stealth fighter that is under development at Chengdu, but a navalized J-11 derivative being developed by Shenyang. The article also suggests that full-scale production of the WS-10A for incorporation into the J-11B has been delayed until 2011.

Just because Janes regurgitates something one of its writers found here or on another China watching site, does not make it credible. Note that the article states "If the developmental timeline laid out is accurate, ...", meaning they are guessing too.

Here's what the article says:

"
...
The design growth chart for engines produced by three of China's main propulsion system centres - Liyang Aero-Engine Corporation (LYAC) in Guizhou, Liming Aero-Engine Manufacturing Corporation (LMAC) in Shenyang and Xi'an Aero-Engine Corporation (XAC) - has been obtained by Jane's
.

The chart shows a clear plan for increasing the thrust and performance of China's major military engine designs, as well as confirming the existence of aircraft programmes currently in development.

If the developmental timeline laid out is accurate, Chinese industry is well on its way to weaning itself from its current dependence on Russian industry as a source of engines for its most advanced fighter aircraft. Currently, China depends totally upon Russia for two of its most advanced fighter aircraft that are offered for export.
.....
The WS-10A Taihang supposedly completed its endurance tests in 2005, but the milestone chart for Chinese engine development displayed by China's AVIC consortium at Air Show China 2008 in Zhuhai does not show the engine entering service until 2011.
"

Interesting developments btw, lots of exciting time for the Chinese Industry ahead. No mention of the WS-13 engine by jane's which is a bit strange.

in which case, imo, it's not very well researched, because J-11B right now is exclusively going with WS-10A and J-10 will be switching over to WS-10A once they've sorted out all the minor problems they have with it (and I hear, there are a lot, I mean a lot!)

As sceptical as I am about anything coming from Jane's, to be fair they did say 'currently' which means for a written article by Jane's 'several months ago'.

Chinese jet engine technology is 30 years behind that of US,consider the WS-10 T:W ratio at 7.5,by contrast F-404 is 9.2,F-414 even better 9.7,Eurojet for EF-2000 is quated at 10.result was smaller more compact more thrust.

The full article does mention the WS-12 (Only a portion of the article is available on-line). I agree that the omission of the WS-13 is odd - since previous Jane's articles have mentioned the engine.
