    Second phase engines are supposed to be projected to use flat nozzles. We will see. Around 2016. 3D is possible with flat nozzles, but i really doubt they will bother. They hope to bring the loss of thrust down to 2-3 %, so it wont be too bad.

    PAk-FA FLAT 3d Nozzle with partial air intake from above to reduce IR signature and maximize stealth

    How the 3D deflection works?

    BTW, are those in the first pic brake deflectors like on the Tornado?

    Photoshop. It would be cool if someone could photoshop some PAK-FA and Su-35S pics into the new dark-grey livery of the Russian Air Force. Just to see how they would look.

    So.

    Two different photographers post two different pictures taken at different times showing the exact same photoshop, and one of them posted on Airliners, which is very strict to not have PS pictures. You two are Titans of logical thinking, congrats.

    Not to mention you have to have the medical condition known as being blind, to not see difference in details between T-50-1 and -2 tails. And you can see those specifics on the new pics.

    Actually, I was looking for some rumors regarding this change. So, T50-1 is grounded for whatever reasons and both have had their tail fins changed at least once. There was also a change in the T50-3 in the same parts. Is it related? Any other news regarding the latest prototype?

    And what about the Sukhoi's surprise for the next months?

    That's not what defines 3D TVC. The engines fitted to the PAK-FA currently have canted 2D nozzles (which is referred to as 2.5D)

    The "Photoshop" was an announcement for the picture I posted, before any discussions erupt that it is fake and blablabla...of course it's fake. I am aware that the 51 vert.-tail on the 52 airframe pics are real, I am not doubting that and the comment from above saying that they are fake doesn't make sense.

    Excellent, then we agree.

    Maybe they are thrust reversers and air brakes, and when not in use as brakes they are low observable exhaust nozzle
    It would be great to see some system like that on this plane for real

    I could see the thing sliding upwards to direct thrust down or swinging downwards to direct thrust up. Not sure how to make side to side stuff.

    They could just do it how it is at the moment. The current engines on the PAKFA and the MKI do not swing side to side, only up and down. They are canted however at i think 15 degrees, which means that you get a sideways component. It's sometimes called 2.5D thrust vectoring (as opposed to true 3D thrust vectoring which is only really on the Mig-29 OVT demonstrator).
