Re: New Generation Fighter
sory, but this thread is so busy,the page go too fast, no body want to check back, so many same photos appeared in here, but I think it's ok, because many people didn't see all photos, they are hard to go back to find it.
the thread is explosive!!!
this one is amazing.

If not already mentioned, i would add that a so big nose could allow the displacement of a lot of AESA T/R modules, thus resulting in a very powerful radar . For example USA source stated that F35 will use advanced avionics compared to F22, but due to airframe limitations the radar of F35 will have shorter detection range than the one onboard on F22: maybe china opted for this design to compensate the J20 disavantage with USA avionics/stealth (or maybe is only a matter of aereodinamic of the plane)
For me, same as above, not only if the engines are already chinese that would be the first 100% chinese plane, and would be strange considered how advanced it is (J10 still uses AL31, and J11B, with chinese engines, is directly derived from russian airframe) but is also "suspicious" the appearance of two article in these days, in Jane's and in WPost, that state basically that China is incapable to build reliable turbofans: they would lose face if this situation is gonna change so soon and the issue timing of these article could be related exactly to J20.

Re: New Generation Fighter
- 3D TVC like T-50 can't be made stealthy and a very heavy
- 2D TVC like F-22 can be stealthy but add weight
- No TVC can be stealthy (with square exhaust) and are lightest
TVC is mostly effective for nose-pointing (and shoot) maneuvers at subsonic speeds. At high speeds, TVC has little effect on maneuverability / agility compared to flight control surfaces like canards or LERX.
Since J-20 is the only canard stealth fighter, it has less need for TVC compared to F-22. Unless subsonic nose-pointing maneuvers are very important in PLAAF doctrine, J-20 can do without it (end up with a lighter aircraft).
That said, J-20 obviously doesn't have the IR signature reducing nozzles of F-22.
I don't think the T-50 engine is well integrated at all.
I think you stop beating a dead horse, not ride it.
TVC engines are a trade-off:
- 3D TVC like T-50 can't be made stealthy and a very heavy
- 2D TVC like F-22 can be stealthy but add weight
- No TVC can be stealthy (with square exhaust) and are lightest

It's not a Russian engine or else they would be bragging about it already. Maya already said the J-20 would be powered by FWS10A before WS-15 is ready. So there's your answer everybody.
I think you are referring to the rear-shot photo. I think that photo angle just makes the engine nacelles look conventional, almost like JH-7A. But if you look at the side views (not clear because everything is black and ventral fins are in the way) the fuselage tapers off toward the rear just like the F-22.

Please see my reply to Subedei above. I think that's an artifact of the photo. The fuselage actually does taper to the rear just like F-22.
What are those things? Even on regular 4G aircraft you don't have bulbs that large. I think they are some kind of sensor, or flight testing instrument for the prototype.
Yes, that makes sense! There is a distinct upward cant on the canard that's not seen on any other canard delta. Eurofighter has a downward cant.
Please see my reply to kursed.

Thnx Mao/MWRYUM. The J-10s look puny in comparison.

Re: New Generation Fighter
Stealth? Carlos Copp says J-20 is just as good.
Super-maneuverability? Canard delta should win in transonic / supersonic engagement. Carlos Copp is sure impressed.
Supercruise? With reported WS-15 specs, should be on par with F-22.
Short take-off? Probably not.... kind of heavy.... unless you have 2D TVC.
It would be interesting to back several years to see which forum member was the most accurate in predicting the development speed of J-20.
That makes sense, plenty of room for radar and IRST (not bulging out).
I doubt J-20 is at any disadvantage compared to the F-22

Carlos Copp basically says J-20 should be at least equal to F-22 and even exceed in internal weapons carry and range. Carlos Copp actually underestimated the J-20 when he said that China's AESA is not demonstrated. In fact, AESA was already tested on J-10B last year. Moreover, China fielded AESA back in 2003 on the Type 052C destroyer.
