Is this the first time J-20A with WS-15 has been spotted with stealth coating and not yellow primer?
If so, this is the culmination of decade plus of watching J-20 grow up into its final form. It looks so amazing, like some deadly sky spider.
It's not fully clear if that specific airframe is using WS-15s or WS-10s, based on the appearance of the silver band around its engine nozzle and other minor features.
But in any case it's just a matter of time.
WS-10C2 also has con-di nozzles.
From what I’ve heard WS-10C2 has better fuel efficiency than WS-15, which is a bit of a leaky turbojet. It is possible that the two engine variants will coexist to fill respective niches (range/loitering time vs speed/kinematics/power generation).
Disagree. If there's one thing that the J-20 doesn't lack it's fuel/combat radius. There's simply no point.
Besides, I'm inclined to believe that with the dorsal hump (which introduces more space for fuel) and faster superscruise speed introduced by the WS-15s, the J-20A will reach a new equilibrium between combat radius and loiter time.
And who knows, from what I've heard, there's some neat tricks applied on the WS-15 that might make it not so fuel hungry after all...
To add onto what alfa particle said -- even if WS-10 had a marginally better fuel efficiency than WS-15 in certain flight regimes due to bypass ratio differences, whether it would translate to meaningful real world gains in combat radius to warrant active production/procurement of the same aircraft with two different engines (and the logistical difficulties that would entail for the long term, and ignoring the other capability uplifts that WS-15 offers), is very very doubtful.
The idea of "actively producing an aircraft with two different engines" (if not constrained by engine production rates, reliability, political or diversification concerns etc) is a very wild one which imo can't just be thrown out there as if it were a casual suggestion.
Do we know that for sure? If i understand correctly, long range of J-20 is speculative, and maybe even an overflow of interceptor theories.
For J-36/SH it's way more obvious; J-20 ultimately carries 4 FTs, unlikely corresponding plumbing was added to the airframe just because.
(not arguing the point that it's pointless to mix different engines for marginal differences).
While I agree with the thrust of your point I do think the WS-10C2 will end up being adopted en masse just for MLU of earlier J-20 airframes. And I suspect the J-20S might end up sticking with the WS-10C2 as well.
