Ws10a

Incredible!! The General did in no uncertain terms indicate testings presently goes smoothly. Thanks Maya

Apologies if I'm being a bit daft, but which end of the WS-15 image on the chart is the nozzle and which one is the inlet? (like.. the right end or the left end? )

Please and thank you

(Also, whichever end the nozzle is, it looks like it isn't particularly stealthy - the F-119 has that unique rectangular TVC nozzle which has lots of serrations. From what I can see here, if that pic does indeed display the WS-15, then it's nozzle looks like it currently doesn't emulate the same stealthy physical design. Dang)

the black section is an inlet. intalling those is just for core engine tests(to simulate the conditions )

the WS-15 looks odd. Is that the complete engine or just the engine core?

Looks to me, all the engines are pictured with the air intake on the right side.

Looks like the air intake fan was not installed on the WS-15

All the others are positioned that way, but it sure looks like the WS15 is facing the other direction. I find it odd that the timelines says the WS13 was appear AFTER the WS15. Something about the timeline they give doesn't seem to make sense.

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. 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.

So it maybe after all 2-variants of the FWS-10? For several years I have read (not officially. just internet stuff) that the full-augmentation for the WS-10A as being 132kN. The officially released specs for the FSW-10 put it at 125kN.

So could it be :

FSW-10 : 125kN (in mass-production, according to the aviation museum exbhibit and the CCTV video)
FSW-10A : 132kN (Uprated version. Not yet ready. Probably the version that has been suffering quality issues)

Looks like they went back to the WS-10 apparently. Sometimes the enemy of good enough is perfect.

The WS-10A could have Thrust Vectoring but I thought they'd save that for later.

Could someone clear a thing up for me? I'm getting an impression that the major problems with the WS10 have been solved and they have started the mass production. Is this true?

There is growing (almost definitive) evidence that the WS-10 is in mass production. But there still is no evidence it is being used on the single engine J10. I don't think they have enough confidence in it on a single engine fighter.

What i would ask is:

1. When do we think the WS-10 went into full production?
2. How many new J-10s photos have we seen since then that are taken say six months after the start of the assumed mass production.

I think considering the proportion of WS-10s out there compared to AL-31FNs, and that they have been out there for just a short time, photos will be difficult to find unless the PLAAF decides to reveal the WS.

J-11B powered by FWS-10s

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?
