Color of the plumes has to do with exhaust temperature and is not a reliable indicator of engine type. That said, the nozzles definitely show WS-15.


Really? I agree with you that we've seen this yellow/orange exhaust already before ...

... but even if I try to enlarge and up-scale that image, I see nothing that looks "definitely" like a WS-15?! IMO it is simply too small.

The WS-10C nozzle has a sort of silver collar at the base near where it joins the fuselage

The WS-15 is all black. That and the colour of the exhaust - probably at a lower temperature due to IR reduction techniques - is good indication that this is a WS-15. It should not be unusual to see it on new airframes since we have an indication that the engine is in some form of mass production.

Yes, but isn't this a "a sort of silver collar at the base near where it joins the fuselage"?

The WS-10C has a double ring structure at the nozzle exit. Doesn’t look like the engines in either of the pictures above have that.
