AVIC website list WS-10 as 132kn thrust. Al-31Fn is well known at 125kn.
WS-10A is not reliable. You must be kidding? You are telling me Chinese who are ultra conservative military risk taker will use a not so reliable engine for prototype first flight test? Seriously do you know how dangerous and risky is it for an initial test flight? Chinese will never use an unproven and not so reliable engine to power their prototype like J-16 and J-15s. I will rank it even more dangerous than flying a proven single engine aircraft.
I am not rubbishing. Use yr analysis and think about it. SAC new fighter and prototype are all receving domestic engine. What makes J-10 so special that its not using it? Just becos its single engine(See above of my comment)?
J-20 is an high priority project which I think Shenyang dare not mess around. But J-10 is an different ball. J-10 role can be replace by SAC J-11B product if neccessary. By delaying it and try to manipulate the top level decision to endorse more of their product is possible.
The only way Chengdu can counter will be to breakfree from Shenyang limitation of engine supply by buying Russians.
in the Zhuhai air show, AVIC1 said the thrust of taihang is 12.5 ton, basically the same as AL-31FN.
If you go look in the WS-10 thread, you would've seen Maya (who is as knowledgeable on this topic as anyone we know) state that the engine developed for J-10 is different from the one used on J-11. One is FWS-10 for flankers and the other is FWS-10A for J-10. It probably has higher thrust and reliability requirements along with the gearbox on the bottom. Now, FWS-10 appears to reliable enough for new aircraft now. The latter has been testing on prototype 1035 for a while now. I don't know what its status is. PLAAF will use it when it's a better option than AL-31FN. That's how it is. You seem to not even realize that FWS-10 and FWS-10A are separate projects. Whether or not FWS-10A has achieved its original requirement at this point, we don't really know.
J-10's role cannot be replaced by J-11B, lol. J-10 is currently the most capable air superiority fighter jet in service with PLAAF.
Why does CAC even bother to produce a prototype that tests with taihang if it knows it can't get an engine from Shenyang liming? Why does CAC have to use FWS-10A for J-10B? If the Russians can offer a variant of AL-31FN with higher thrust (let's say 140 kn) and longer service life if 99M series ever goes production, why should CAC have to use FWS-10A? Why would PLAAF allow its most capable fighter jet jeopardized by pettiness from Shenyang?
Do you realize that WS-18 and WS-118 design work are all done by SAERI (Shenyang Aeroengine Research Institute) but the actual production will be done by Xi'an Aero-engine group? If we go by your theory that SAC can prioritize all of its own guys to suppress other AVIC1 entities, then how does something developed by SAERI not be produced by Shenyang Liming, by Xi'an AE? I think it's also the case for WS-15, but I'm not 100% sure.
Do you realize that 1/3 of the work for FWS-10 is done by Xi'an AE? Do you think they would put up with such a nefarious scheme by Shenyang Liming?
