What is that?
Let's hope rumors are wrong for once
I suppose the close proximity of the two nozzles won't adversely effect tvc in any way (flanker, t-50)?
"Now being researched, fluidic injection nozzles divert thrust via fluid effects.[1] Tests show that air forced into a jet engine exhaust stream can deflect thrust up to 15 degrees. Such nozzles are desirable for their lower: mass and cost (up to 50% less), inertia (for faster, stronger control response), complexity (mechanically simpler, fewer or no moving parts or surfaces, less maintenance), and radar cross section for stealth. This will likely be used in many unmanned aerial vehicle (UAVs), and 6th generation fighter aircraft."
Via wiki. A lot of talk about this stuff going into 6th generation air frames.
Well, they would still need slots and openings to control the airflow into the nozzle to deflect the thrust. I personally don't think it's going to happen with the J-20, but it's entertaining to speculate

Despite of how cheap the J-20 will be, it would still be multiple times more expensive than the F22, comparatively speaking in relation to GDP and GNP. I have seen a post somewhere before, saying that even J-10 is more expensive than F22. This guy calculated the overall resources (not just natural resources alone, but a broader meaning) a nation has and how many hours of labour/work/effort per citizen to create enough resources to build the jet. According to his calculation, the F22 consumes less effort from the American workforce than does the J-10. This is very pragmatic approach to evaluate.
For example, a wealthy man with fortune in the tens of millions told a middle class blue-collar that BMWs are cheap, he should buy it, because Ferraris are too expensive for him. This wealthy man is half correct, because this blue-collar definitely could not afford the Ferrari. But the BMW is still too expensive for him. It is achievable, but the car loans would drain all his dispensable income. On the other hand, Ferraris are very expensive, but with this man's fortune, he could buy hundreds of them as if they were toys. Although expensive, they are cheap for this millionaire.
Get the moral of the story?

Now you're just splitting hairs
If we were doing it that way, why don't we also find the ratio of GDP to living costs, before finding the cost of a J-20 to its society? Surely you're not suggesting that the basic living costs for China and the US are the same?
If you're going by a broader measure of capital resources to determine costs, also keep in mind that China has four times the population of the US, so it would lose only a fourth of the comparative human resource that the US would lose to create the same output assuming the same efficiency. The way you've presented such an analysis is overly simplistic and doesn't look at how different production factors would behave differently given their different contexts.

Yep. Its kinda disappointing if production j-20 ends up being less stealthy than Pak fa and f-22, the sound of things is that t-50's gonna get f-22 style rectangular nozzles.
I don't know if I believe that. Some buzz of that abound on keypublishing, but I haven't seen any first hand sources, and that the one render they had of the PAK-FA with 2D nozzles had orthogonal angles, which would present corner reflectors for radar (which tells me it's probably a fan render).
