How about the proposed Su-19 with the new wings, how would it stack up against the F-4E?

There will not be anymore(your words) ‘dedicaded Interceptor’ ever again.
The last one is the Mig-31, not sure about the F-22 though(it has poor range)..
The Flanker design is not a dedicated interceptor, but its classify as an heavy Interceptor, even if it has other great performance too!

It has something to do with Internal fuel capasity, speed, weapons load and a powerfull radar(sensors) first and formost.
All these transform into a larger airframe design then the ussual fighter design.
Yet as a Interceptor the Flanker is a air superiority with multirole capability too.
I’m sure the J-20 will have some multirole capability.

I did not say ‘dedicated Interceptor’.. you did..:rolleyes:

The J-20 is a heavy Interceptor class aircraft, now deal with it!

The term interceptor specifically refers to dedicated interceptors like the F-106, MiG-31, etc. By definition they are highly specialized aircraft. The Flankers, Eagles, and Raptors are air supremacy fighters. Although they are capable of the interceptor role they are not called interceptors.

Now that nomenclature is established, I propose we move on.

So it’s confirmed SAC is going forward with their 5th generation fighter. But if the project is successful will only be for domestic orders, implying the J-20 would be allowed to be exported. Interesting.

What is the reason the Russian engine is used for J-10B while the Chinese engine is used for the J-11? Seems counter-intuitive.

The wind tunnel testing seem to test almost every modern aircraft type, but they never seem to give any love to the X-32. You would think the wing design would be at least of some interest to those with stealth aircraft projects.

So, about the alleged variable geometry DSI intake. If this works what would be the attainable top speed of the J-20 compared with the F-22 and T-50?

The goal of J-11B is not to be better than J-11 (and in my opinion it is not) but to be all Chinese.

Why would those two goals be mutually exclusive?

I wouldn’t be surprised if one day in the near future we see blurry images of an advanced strategic bomber. If China wants the ability to strike at carriers and air bases out to Guam they need that platform. It’s even more important than having a stealth fighter.

While ppl may put too much emphasis on the aero-dynamic aspects but ignored the weakness of Chinese aviation power plants. The engine for global hawk is optimized for high latitudes, long haul flight but Chinese haven’t put into service any engine rivals that of GH. I guess what power plants available? WS 13 turbofan? I’m not sure it has undergone that high latitude test or not. WP13 turbojet, yea, it’s proven when it powers J8 High latitude high speed jet. Eventhough, all these, without afterburner, will not give satisfactory oil consumption.

No doubt the powerplant is a major limiting factor. But Distiller’s opinion is the wings themselves are also a limiting factor for max range. My question is why chose the boxed wing if it’s too thin for fuel tanks? It seems maximum endurance is not of primary concern to the designers.

Very thin and light wing. Look how it/they drop/s on that photo. No fuel in them I’d say.

Compare: http://www.globalsecurity.org/intell/systems/images/global-hawk_020426_52.jpg

That’s a good point. So why didn’t they go with a conventional high aspect ratio wing like the Global Hawk? Why go for an unconventional boxed wing when it robs fuel capacity and range?

My point is that they have made stunning progress anyway. But you can progress that fast as it is showed.

Look at other Asian countries.
South Korea – first F-16 license, later the T-50 that fits somewhere between combat aircrafts and trainers.

Japan – F-15 license for many years, later not so successful F-2.

India – the Su-30 license and lots of experience on upgrades, but Tejas seems to fit same class as combat T-50

Those countries had full support of US, Russia and/or other countries aviation industries (the landing gear of T-50 was designed by Dassault).

At same time the Chinese would develop such a growth in isolation?

That’s because those country’s aviation industries suck, being too dependent on imports.
