And I think now the Russian regretting of not selling AL-41F to China
One thing that I like to see some clarification on for WS-10 variants. Is the WS-10A only used on J-11/J-16 and the WS-10B only used on J-10? I’ve heard conflicting information on this matter, since I had always assumed the A goes on Flankers while the B goes on J-10 and the C goes on J-20, but I’ve also seen reports of WS-10B on the J-16.
My impression was WS-10B has completely replaced WS-10A in all application. People have been saying WS-10A was only used briefly on J-11. Subsequent J-11 and J-16 were all WS-10B. However, it is just hearsay.
J-11B I think in the 2012-2015 timeframe.

Looks like a pressure chamber, so probably an engine test bench meant to simulate different altitude and flight conditions.The banner reads "祝贺空天动力试验台顺利进入系统联调", which roughly translates into "Celebrating the smooth transition into systematic calibration/debugging phase of a aero-engine test bench". I wonder if this might have something to do with this, although the model doesn't quite exactly match this.
They may have to stick with the AL-41F1 even longer than planned if the slow testing pace of the izd.30 is anything to go by. With the Su-57 nacelle size being largely the same as a Flanker, they can’t afford to go much different in size than the AL-31 family like the AL-41F1. Maybe the silver lining is that when the izd.30 is finally finished, whenever that it can be used in Flankers too.
Frankly the Russians may have been too ambitious here, because they want to keep such high performance that’s better than F119 while being the same footprint as AL-41F1, which is similar to F110 in size. According to Japanese papers on their XF9-1 engine, the F119 inlet diameter is almost 1m which would suggest 950mm or more if that value is rounded. Compare to 905mm for AL-31F, and 932mm for AL-41F1/F1S, and 35.66” or 906mm for F110-GE-400. The Russians may trying to do something that’s beyond what they can make affordable or be durable enough. Though honestly even Japan’s goal with XF9-1 might be too much of a reach, they’re trying to have F119 thrust levels while being similar size as the F110.
Next to nothing is known about the WS-15, so I don’t know just how ambitious China is with this engine. They’re well within a generation of the Russians when it comes to fighter engines, but with vastly more funding available there’s a possibility that it reaches service before izd.30. That said, I don’t know if the WS-15 is attempting to keep the same footprint as the AL-31 family since it’s optimized for J-20 from the beginning.
