S-400 isn’t offered currently and for a long time for export to anyone.

Chinese won because they offered tech transfer and also were by far the cheapest.

God forbid, Chinese win cannot have anything to do with specs…. :dev2:

@LEG,

You are trying to hard 🙂 I will be a little harsh but your wall of analysis means almost nothing because it depends on myths created on these forums such as J-20’s “huge” size or “small” wing area.

Designer of J-20 states that they aimed for “4S -super cruise, super maneuverability, short take off and stealth ” which has quite a lot weight for my perception than anything written here.

J-20 has been developed for air superiority and not seeing it as such a design is just funny and not smt I can take serious :D.

Remarkable.

I’m going to the Zhuhai airshow in a few days – what can I expect to see ???

J-20 or J-31 would be brilliant – but I doubt it 🙁

J-11 or J-15 would be a bonus….. 🙂

But probably just J-8F, JH-7, H-6H, J-10 – same as 2010.

Great NEWS!!! Share pictures here, please 🙂

That is the problem. Looks can be deceiving.

When you look at the numbers nothing is out of ordinary about J-20.

I am ONLY trying to defend MATH! Nothing else TR1. When you look at the ratios PAK-FA is more “interceptor” than J-20 😀

1) too long ==> not true.

2) wing span is too short ==> not true.

So…???

What’s annoying is advocating something that is simply wrong and also deriving conclusions based on wrong “data”.

There are no numbers as we speak. All we got is an optical impression.. and for me this clearly says the type LOOKS extremely long. It’s no coincidence that you won’t find a single poster claiming the same about say T-50 or Rafale – because they obviously look different.

What makes you think that you got any right to interfere with this impression of mine and tell me “you’re blind, the J-20 is not long” is beyond me. I will ALWAYS trust my eyes much more than claims of some guy from other corner of the planet and there is nothing you can do about it.

Nope. I claim it looks more like interceptor not that it is one. I don’t know its specific role – the Chinese are free to use it even in a display team of six if they see fit. I certainly don’t care.

I have already made my point here. In my previous response I have shown you that the engines of the F-22 are positioned much closer to the center of gravity and that hull of the F-22 (only the airframe, sans stabilators or fins) is MUCH shorter than the hull of the J-20 – say ~16.5m to ~20.5m. You have conveniently chosen to ignore it and not respond to this – OK, feel free to continue your whining and telling everyone that only the absolute length counts and that the tail booms of the F-22 have the same impact on aircraft’s inertia as the massive J-20’s tail structure.

As already said, you can use even a MiG-23 or a J-8II as air superiority fighter. Don’t mind the results, though, but yes, you can use them. But I feel pity for a future Chinese pilot trying to turn the J-20 tight with an F-22 on his tail. The J-20 certainly doesn’t look like much of a hot-rod.

At least be sincere. You are claiming J-20 is an interceptor. You are comparing it to J-8 then saying “good luck with the tight turns etc”. Be bold, don’t be shy. 🙂 You are saying it is too long to be an air superiotry fighter. Don’t you? Am I reading wrong???? :rolleyes:

Also, if you want you can use it as a bomber, too. That is not the point. The point is you are saying it is not designed for air superiority. Or don’t you?? 🙂

By the way, I dint ignore any of your points, I said J-20 body is longer than F-22’s, definitely not by 20% though. Exhaust to nose length for F-22 is still longer than 17m and J-20 is shorter than 20m when you exclude tails. Difference is probably around ~2.5 meters. But you have to accept that tail structure of F-22 is much more massive than that of J-20. It is completely fair to compare their absolute lengths.

I guess you have the impression of F-22 is a tiny jet 🙂 You know what, it is bigger and heavier than even F-4 😉 It’s empty weight is 19,7 tonnes! 5 tonnes more than an that of F-15E. 🙂 I will be bold have a wild guess here and tell you J-20 empty wight will be almost identical to that of F-22 🙂

I will repeat myself. By looking at dimensions it is really hard and requires some talent to say “J-20 is not designed for air-superiority.”

A good picture that shows ratios of J-20 (you can come up with your own estimates about wing span emile come on use some engineering knowledge of yours :), your welcome ):

Does it still looks like an interceptor?? All interceptors need those canards and wing span 😉

I’d like to see where and who told that red words you quoted, and clearly you have no idea about engineering. Don’t you remain any space between missile and bulkhead for the data kept shorter than 21meter?

It is simple as your thought.

We will see what if the wing span really is around 14 meters which you gave no interval deliberately or undeliberately:D

Well, don’t get nervous, it wasn’t you. Owner of those words can write about it if he wants.

For the wing span, you can measure some pixels for yourself and see what’s what? 🙂 I did, so with your enormous engineering “knowledge”, I believe you can do it, too 😀

Also, what’s so disturbing about J-20’s dimensions for you guys??? I gave my estimates over and over L:21, WS:14. What’s so difficult to accept about these? What’s your estimates????

I am writing about pixel ratios and the outcome estimations I have. It is extremely straight forward really.
