The nozzles look wider which also seems to reduce the taper on the nacelles. Would be surprised if we get an MLU with WS-15 tbh. Ironically if the WS-10 mounted J20s do receive an engine MLU it might be a further improved WS-10 lol.

Although, looking at more pictures of 2052 and 2055 prototypes, it doesn’t look like the nacelles are any different, just the nozzles. Inlet doesn’t seem to have changed either. There’s potentially about 300 of these before production really transitions to J-20A in a few years, which is quite a large force that would have older engines. That’s why I’m curious about whether these current production aircraft are compatible with the WS-15.

How they believe that is simply the DSI. That’s the origin.
Shit flavored chocolate is better than chocolate flavored shit. Boo hoo big deal.
By wider do you mean the petals of WS-15 being longer than WS-10? If so I don't think that indicate WS-15 having a larger diameter.
The petals of WS-10 without the induction channel look longer than ordinary WS-10 too, in the same effect as WS-15.
WS-15 probably uses conventional CD nozzle unlike the WS-10 which has an induction + CD nozzle. The outer petals of WS-10 is shorter because it is designed to converge less than the convergence section of a usual CD nozzle. The inner petals of WS-10 and the induced air in between all works for the purpose, so the demand for the outer petals' change of cross-section is less.
Are you sure that WS-15 photo is real?
I took that photo from Deino's post in this thread.
No I mean I think the engine diameter looks wider. I’m aware the WS-15 nozzles are longer too but that’s not what I was referring to.
I don’t think WS-15 is much bigger than the AL-31FM2 or WS-10C, likely not F135 size, but maybe close to F119 size. The nozzles look larger but the nacelles and inlets didn’t seem to change from current production.
