Serrating it will help...but they also need to better hide the IR signature IMHO. Something like these:

A scale model of J-20 showing possible loadout
This model is probably from when J-20 first came out. It shows F-22 type side missile bay firing mechanism rather than the 'peek through the zipper' (lol) type seen in the latter J-20 videos.
WS15 only has Axisymmetric Vectoring Exhaust Nozzle, so I doubt that J20 will be equipping any kind of 2D nozzle in foreseeable future.
Those F-22 Nozzles were highly classified, and no one took pictures of them, period. LOL really they were?
There is substantial weight and some performance penalty associated with f-22's thrust vectoring stealth nozzles. There is also likely some weight and performance penalty associate with yo-23's non-vectoring IR suppressed nozzles. Given the fact that engine development is clearly the weakest link in China's fighter program, and it is not a stretch to say at least major parts of current Chinese engine technology is still below the level at which the F-119 and F-120 engines for the f-22 and yf-23 were designed, I think minimizing avoidable weight and performance penalties would be a high priority in j-20 design if j-20 were intended to be kinematically competitive with G4.5 and G5 fighters sometime in the near future. So I don't think we would likely see a major redesign of j-20 to incorporate stealth or vectoring nozzles any time soon.

Hmm. I don't recall seeing these ground crew guys since the first 2001 prototype.
Never mind I saw a photo of them with 2011.

A report last year by official aviation news agency revealed a new "low observable nozzle" patent. And what is interesting is that it claims this is the world's first low observable AVEN.
Here is the PDF

Check out the FC-31 model with serrated nozzle. I bet J-20's will almost look the same.
That we would all be in ecstatic mode... Feels so HIGH

Yes, Serrated is the official term, now I know.
The "jagged jaw designs" that I mentioned in those previous posts, is in fact termed "Serrated".
Thanks for reminding. LOL

Guys, is it true that thrust vectoring would cause the useful lifespan of the engine noozles to damage easily?
