could you point out which picture?

The ones posted by starikki, the first one, on the underside, there is a feint white line running along the centre line. On the last photo, look carefully on the side of the intake, there does appear to be a long rectangular panel.

Here comes weapons bay:D

Are you mistaking one of the undercarriage bay doors for a weapon bay door?

Congratulations to China 🙂

This jet is “bizarre” , very strangely designed .
It is clear that the Chinese have their way …:cool:

Witnesses say that it is very stable in flight and the landing was very smooth .
The fact that they used domestic engines for the first flight tells us about how much they trust their own stuff .
They learn fast , real fast .
I still find the overall design rather … strange . I would like to see its manoeuvrability in subsonic regimes and its ability at dogfighting … :rolleyes:

Agree with you regarding the unique design. It looks like one of those designs which shouldn’t really be able to fly…but it does somehow 🙂

Correct me if I’m wrong, but isn’t this the first flying twin enginned, twin fin, delta-canard fighter? Did the Mig 1.44 ever fly?

Notice that too, what function does this twist perform in aerodynamics?

Delays wingtip stalling, reduces wingtip vortex formation and, more importantly, reduces boundary layer separation, i.e. inhibits airflow from travelling along the leading edge of the wing, rather than over the wing.

Previous designs have used ‘dog tooth’ notches in the leading edge of the wing, or sometimes even in LERX, such as the Mig-23. Overall, it improves the efficiency of the wing. This is particularly important for sustained high speed performance, such as supercruising, such as the F-22, and hence, maybe even for the J-20?

She has a really cute ass! 🙂

The twist near the wing tips is also quite visible in the above pic, a la Raptor style.

Guys, come on, it’s rather premature to be discussing this topic isn’t it? We don’t really know the specs of the aircraft yet, so any comparison with the PAKFA, especially in terms of export potential, is all rather pointless. Heck, we don’t even know the full specs of the PAKFA yet.

What’s more, both these projects are at the prototype/tech demonstrator stage, so there’s plenty of potential for further changes and developments over the next 5-10 years.

What’s more, I doubt whether the potential export customers listed so far have the need for such large, complex, resource intensive aircraft in operation. A much smaller, simpler, single-engined aircraft would fit the requirement, and with a price tag of USD50 mn or less.

Now there’s a question for a thread topic; is it possible to develop a 5G fighter which costs USD50 mn or less?

# It will have a decent range, its fat, will carry large amount of internal fuel. If it is as big as it looks.
# Most realistically its currently powered by AL-31 engine variant, will need IMHO minimum of 160kN+ thrust engine, considering its lumpy frontal cross-section shape.

I think it’s shear size has surprised quite a few, I was expecting something more ‘sleeker’, with a smaller frontal nose section. Moreover, the central fuselage section reminds me of the J-8 Finback, long, flat surface to house large engines and fuel.
