Do you see now -- why debating these guys are so entertaining ?NO !
矢量噴管 Folks, does these pictures look like J-20 has thrust vectoring to you.
The last picture clearly shows the nozzles are pointing downward to me.
No looks closer. Its just looks tilted because of the reflection on top of the nozzle and the shadow at the bottom.
Unequally expanded nozzles, right (in picture left) iris is simply bigger, and the iris center is generaly not on same level as the bottom red line so at this angle of the photoshot it will appear perpendicular shifted to the left because of perspective and well just generally perspective and possibly some lens distortion tooWhat about another picture with several green, red and yellow reference lines drawn?
People who aruges that J-20 used TVC nozzles always posts pictures that might make you think the nozzles aren't pointing straight if you squint your eyes real hard.
While any proper TVC nozzle will vector over 20 degrees which are easily recognizable beyond dispute.
Think about it:
If J-20 does have TVC, where are the images with the nozzles that are obviously vectoring? (<10deg.)
If J-20 does have TVC but it's disabled to hide this ability, why do we have images that looked like the nozzle is slightly (>5deg.) off center? Is CAC that incompetent that shutting down TVC is not possible?
Why woud CAC give J-20 a TVC at the cost of extra weight just to allow a maximum of >5 degree of vectoring?
There's only one logical conclusion:
There's no evidence to suggest J-20 is equipped with TVC nozzles. The pictures people use to argue that there is are likely illusions caused by lighting, camera lenses or two nozzles at different closed/open state.

Arguing a good turn radius = TVC is like good score in olympics = PED. It could've been executed without TVC. (Also that turn is not that spectacular, a J-10 could've easily done it)The extraordinary tight 180 degrees turn demonstrated by J-20 in the recent video posted in this page is strong evidence of vector thrust. In fact one of the commentator, a former Chinese General said that.

Besides, that turn is 100% documented via HD video, not in a single frame did we see the nozzles turning. (Or if the nozzles did turn, they turned so slight that it's completely unnoticeable) Therefore J-20 did that turn without using TVC, didn't this fact just defeated your point?
I have never seen a fighter with TVC could turn like that in high speed. Show me some videos.
One major reason that I don't believe all J-20 are using AL-31 engines is that its engine sound is completely different to Su-27 and Su-30. And its much louder too.

I assumed you meant "without TVC".I have never seen a fighter with TVC could turn like that in high speed. Show me some videos.
