Finally.... Been waiting for this along time. Was this take before the problems initially started materialize? I mean the initial batch before they reverted to AL-31F? Or a recent image where the engine problems have been sorted out?

HALLELUJAH!! Christmas came a few days late, but it was worth it!! =D (If those pictures weren't PSed by some random twisted bloke...)

I suppose now we just have to wait to see if the WS-10A is introduced on all other Flankers as well (and then the J-10's).

Maya, the WS-10A offers 132 KN of thrust right? (i.e.: better than the Al-31? I'm asking cause it would be sucky if they replace the russian engine with one which is less capable =/)

--Yes, i think so.

re-emphasize that J-11B is equipped with FWS-10 engines,each rated at ~125kN thrust with afterburner(ISA,SLS,uninstalled).

"F" stands for Fadongji(engine in Chinese Phonetic Alphabet/Pinyin ). the FWS-10 is an official designation.

FWS-10A is designed to power J-10.

As regards reliability issues, as far as i know ,most of early problems (especially blades fatigue failure) have been overcome by improvements in materials ,manufacturing process,QC.
wait to see field service results...

The engine that was put on display at the new aerospace museum (next to the AL-31F) is the WS-10 (as indicated by the nameplate). It is very close to completion and may already be in mass production. This engine has 15 guide vanes on the front and a standard-looking nozzle This is the engine that appeared on that assembly line photo behind the chief engineer, this is also the engine that was on that billboard at the 2006 Zhuhai airshow.

But at the 2008 Zhuhai airshow a different engine was displayed. It looks similiar, but has 17 guide vanes and a completely different exaust nozzle. This engine may be more powerful (it has more guide vanes indicating possibly higher air speed) and the nozzle appears to be composed of two independently moving nozzles (one inside the other). he wasn't sure but he thought that this indicated thrust vectoring capability.

that two nozzles are the same.

the 606 institute incorporated many features of D30-F6 and AL-31F into the design of domestic fully adjustable nozzle, such as active/independent control of the subsonic flow petals by means of 18 hydraulic cylinders and aerodynamic control of the supersonic flow petals;similar to AL-31F ,installation of FWS-10/10A requires a set of flexible petals (maybe shroud) to ensure the smooth transition from nacelle to nozzle.

comparison between FWS-10A and D30-F6

maya, what do you think about the rumour that the improved variant of Taihang is getting canceled? I was under the impression that when 4th gen plane takes off, it would be carrying that type of engine.

i seriously doubt that.
Sorry for my late reply.

So i talked to a jet engine expert today and had him look at some of the photos we have of the FWS10 engine.

Based on what he said, I think it's safe to say that at least two variants exist, the WS-10 and WS-10A most likely.

The engine that was put on display at the new aerospace museum (next to the AL-31F) is the WS-10 (as indicated by the nameplate). It is very close to completion and may already be in mass production.

The two WS-10 engines that you referred to, probably have the same kind of nozzle. Just that, in one of them, the petals have moved to a closer position.
Anyhow, the nozzle does look different from that of other usual jet fighter engines. I don't recall seeing this type arrangement in other jet engines.

I've done some more research and i can't say for sure that the nozzles are the same, but they very well could be. But the front of the engines are clearly different. One could be designed for the J11B and the other for the J10.
