as said before, that's definitely AL-31FN.
just look at the unique structure of augmentor flameholders,especially the number of radial gutters...
ps: what "damn things" do you refer to?
Su-34 AL-31FM1

Maya, I don't mean to nitpick, but it's not AL-31FN, it is AL-31F.
If the J-20 is equipped with AL-31F engines, then out initial observations about its takeoff speed were incorrect. Tphuang pointed out that the aircraft took off in a very short distance on its first flight, it was generally believed that the AL-31F would not be capable of this, but of course that is inconclusive.
Furthermore, this assertion would mean that there is, and has been, only ONE J-20 prototype. We do have a very convincing photo or two which shows a J-20 on the runway and another in the hanger...again inconclusive but it would mean these photos are fake. There is no reason to have two prototypes with the only difference being an engine paintjob
I haven't heard any good explanation for painting or coating the nozzle pedals either. Why bother?

Probably testing for different IR and radar suppression methods.Maya, I don't mean to nitpick, but it's not AL-31FN, it is AL-31F.

Thanks for Your reply ... I simply meant "the unique structure of augmentor flameholders,especially the number of radial gutters"

if only paint alone can do the job, i'm more into thinking that the silver paint is actually to blur the nature of the engine itself
noone argues that the black nozzle was not AL-31, but splash a silver paint, everyone come up with all kinds of assumption, and the best part of it, news outlets and rumor mongers have only a shaky ground to stand on
about the take off of the J-20 i would say mediocre performance at best or the pilot just being prudent, preferably the later, because J-20 being grossly underpowered means another challenge to tackle for CAC
Well...RAM is functionally paint. Besides, I'm pretty sure the nozzles themselves are actually replated, and not merely painted on.
If they wanted to create mystery the first pictures of the J-20 wouldn't have had the AL-31 in the first place.
RAM paint also needs certain thickness, and restricted method and condition of application
i am still skeptical about this 'paint', also new 'stealthy' materials for the nozzle
it is the shape of construction that will give the best hint of whether J-20 has LO nozzles or not
the IR signature contributor is the exhaust gas, not the nozzle itself, one either shroud the plume like the F-22, or find ways to cool the gas with mixing with more cool air
how will paint alone or new nozzle material cool the exhaust gas, i have no idea
EM wise it also does not have saw toothing

And we have no way of assessing that.
I'm only presenting it as a possibility.
There is some sawtoothing. I'm saying a silver paint/plating might help shroud the plume. Furthermore those vertical lines on the petal might actually be slots (but it's hard to tell).
By acting as a shroudhow will paint alone or new nozzle material cool the exhaust gas, i have no idea
It has some on the nozzle fairing.
