But I think it seems more promising

Very high and canted wing (losing effective lift, God knows why chinese did it), boxy fuselage, crude fuselage topology conventional delta with relative big wing area, canards, close engine assembling, limiting complex compossed manouvres-combinations for it TVC system

vs

Blended wing, generating full lift, fuselage heavily based on lift body concept, complex surface topology, Levcons, having the balls to stuff the bomb bay at the same level of the wing…

Nope, the J-20 is based on old concepts, this plane is somewhat outdated

more mature than the T-50

You are being driven by appareances, beware, this plane is already painted and looking nice, as the Yf-22 or the x-35 were….

Hint:

The f-35 can’t do any kind of aerobatics yet….unlike the T-50

Nice one, what is this?

Bear in mind that they’re probably bigger than they look, since there is no diverter gap.

The sweept angle of the intake is negative, like the 35’s one, so unlike the T-50/F-22 intake, the intake’s area is definitivelly smaller, add to this the diverter, and you actually get a even smaller intake area.

IMVHO, this plane is not designed for SC, of course i may be wrong.

It then seems quite logical to design the JXX as a bigger missile ship than the F-22

I would be cautious claiming this, because such big weapon’s bay so far away from the center of the main wing would be troublesome for it handling and aerodynamic balance, IMO it bomb bay won’t be that big, so probably is not a striker, just a heavy fighter, or interceptor.

Or probably is a striker 😀

which would suggest a takeoff weight in the 75,000-80,000-lb. class

This is quite a lot, it looks heavy, but not that heavy, never liked the comments from this Mr Sweetman guy…in addition of his clear bias and boring comments based on popular beliefs, he is quite sensationalist.

think the F-23 had clever internal arrangements

If we could give a trophy for ‘the best bomb bay designed for a 5th gen fighter’ the winner should be the PAKFA, although I’s still trying to figure out how the structure is.

IMO the key feature to know if this plane will be successful or not is it weight.

And right now, it looks heavy

I recall saying in the pakfa thread that russians had better to design (IMHO) a delta wing for a medium/light airframe, and this is confirmed, since the pakfa is ‘smaller’ than the su-27 (said by its test pilot)

I recall that if russians wanted to design a heavy class fighter , they better had to go with the su-27 wing, later I found that diagram for a clearly heavier fighter with f-22’s like intakes, faceted flanker nose, and su-27 wings.

It was logic

the J-20 has a delta and seems to be a heavy plane…

Is not a good sign IMO

Anyways let’s wait and see, people here is so much worried for the stealth thing, and probably some chinese engineers are thinking that this plane is doomed from the beginning because more mundane factors (ie, real life)

Of course, if the program is aiming a fighter

Thank you, this can confirm my suspects that the s-duct thing is/was more a flow/hydrodynamic inlet design , rather than a LO measure, this can confirm my other suspects, that the F22 has probably a first generation DSI, with the Typhoon, Rafale and other planes using a mix of this concept with CARET controls, the persistence of the s duct on either LO or non LO aircraft was always bugged me, and such concept was explored also in the 144 and berkut, I always have thought that the s-duct had nothing to do with the stealth thing.

Is probably the true reason why the 22 has a max speed of only M1.8

The J-20 is definitivelly above the F22/T-50 on complexity and ambition, is below the T-50/pakfa on practicity.

Let’s see how this program goes 🙂 , waiting for it first flight

Pure aesthetically, I think the T-50 has a better looking nose

Better one:

Is a beautiful aircraft 🙂

Let’s see how it perform, I still think is a heavy class fighter, the comparison with the F23 is not fair, IMO, this airframe is a compact long structure, while the 23 is basically a flying wing with it fuselage upside down…

The chief designer of the J-14 sneered at the aerodynamics of of PAK_FA during a interview and claim his design to be much more advanced.

To tell the truth, while this is a beautiful plane, the PAKFA has way more advanced aerodynamics, seriously the topology of the T-50 beats every 5th gen plane out there, most likely it LEVCONS are it canards, it small fins are enough for it control, and has shown good flight ability in such short time, while the J-20 need some measures to keep it directional stability (like these fins and the canted wing)

Pakfa ‘true wings’ are very small, leaving most of it lift generation for it lift body, while J-20’s must need very big wings with with a very conventional body that seems does not generate a lot of lift.

In all , both are beautiful planes with some new concepts added, unlike the F22, for example, and much like the F23 ( just in the concept of innovating something)
