J-20 5th Gen Fighter Thread IV (Closed to posting)

Not only the sun must be at the highest point, but also the pilot must be pretty good to be able to land exactly in the center.

Or it could be the afternoon sun was slightly off the highest point and the pilot landed slightly off center, coincidentally making the shadow exactly on the center line.

Again, it could be photo-shopped, or it could be just a rare coincidence and nothing more than that.

For me it looks as if the J-20 is taking off, what could much better explain the position exactly in the middle of the runway ... !

That starboard engine nozzle does look very different in this photo. Does anyone know for sure what that engine is?

I still say it's an AL-31 or variant thereof, just without the black bars on the nozzle.

That's an OVT nozzle and I would say likely PS or CG, better take a closer look, and the right nozzle doesn't appear correct either????

They are the same engines, under different throttle settings.

That left engine def has a 2D nozzle horizontal appearance across the top if you're looking at the same image I am, is it possible we are seeing a different image??? brat

WHOOPS! that is the left horizontal stab masking the nozzle that made it appear flat across the top, I thought someone was playing games with us??? sorry guys

I think the main reason 2011 has put more effort into shielding the engines is because it will likely be the initial production version.

This is the key for me; more but not enough and perhaps too late. If you look at a sideways shot of the 2011, it still does not hide the engine nozzles, as the top of the nozzles still protrudes into view. If they had made this effort with the design of the first prototype they could have completely hidden the nozzles from the side view ala F-35 from the very beginning, but now it seems like they have done the "uh oh we should have thought of this before now" and fixed it as much as they could, though clearly it is not enough. If they keep extending the rear section further back to completely shield the nozzles, they may have to compromise some aspect of the fighter's aerodynamic performance. Or else why didn't they just go ahead and do it?

I think you're reading too much into it. The shots you're referencing are angled and not a full lateral view. Unless they adopt 2D TVC no amount of nesting the engines will hide them from those angles.

Interesting 2 Dimensional Thrust Vectoring concept on J-20.
