In 21st century high tech warfare, China is either take part of hi-tech or will be taken apart by hi-tech.

J20 designed to be powered by Russian engines?
No.

Or you means there is a variant with Russian engines, and China would declare something similar IOC of that variant?

Its powered by WS-10B variant.

Indians think that J-20 can be handled by Rafales.

Even if that were true, they still don't have any.

J-20 is currently flying with either WS-10 or AL-31 depending on the prototype. The initial versions will be flying with WS-1B, but eventually that will be replaced by WS-15.

Why again this stupid question on engine? ... It is clear as hell since years that it is an AL-31 ... No WS-10 ... At least not yet.

sir how do you so sure about it that it is not WS-10?

 

[Djinn]

Only thing to upgrade is engine with the WS-15.

It's only a matter of time that China will crack the engine tech and the moment its done there's no stopping China. China could have also asked the Russians to build them an engine powerful enough to suit the needs of J-20, but the reason i think they didn't avail this option was because of the fact that Chinese own indigenous engine tech has matured up and may be ready within a few years time.

It isnt easy like that to get the engines from Russia.

Sure. The world knows nothing but YOU do. 'Rail gun' ? China is ALWAYS a step or two behind, chasing the U.S. Monkey see, monkey do. They don't invent anything, they just copy and steal.

so the common term is "expect", not "scheduled"

 

[星海军事]

100%

You can't just look at something and copy it,You need samples of it also
How can the chinese copy something they don't have?

This is where you and the Chinese cohort are wrong about the proper context of 'copy'.

It is axiomatic among programmers that everyone literally copy from each other, and I am talking about wholesale sections of codes via the copy/paste utility. In my industry -- semiconductor -- companies routinely buy finished products from their competitors and physically dissect the products to see if there are any components whose final form violated patents. COMPONENTS, not the final larger product.

People can deny, until their faces are blue, that the J-20 did not came from the MIG 1.44 project. They will point out the surface physical differences as 'proof' that there were no copying. But they are wrong in the eyes of aviation professionals. China did not have a native aviation industry in the mold of how a truly indigenous industry come about. The aircraft came to China in finished form and that finished form came from efforts like the Wright Flyer and later evolution. In other words, China never had her own version of the Wright Flyer.

That is NOT a point to ridicule China. No country invents everything. Every country copied, either cooperatively or non.

The fact that China leaped from importing her combat fighters to the J-20 is immediately suspect, especially when the final form is strikingly familiar. Even the Iranians are not calling their modified F-5s something new. The J-20 took the 1.44's final form and refined it to meet modern day's combat necessities. Instead of a mechanical flight control system, the J-20 have fly-by-wire avionics, a concept that is not native to China. If we can examine the J-20 the way the US examined the MIG-25 back in 1976, there will be a long list of components that are either literally copied in forms or at least in concepts. To copy and adapt are themselves impressive accomplishments.

So Mig 1.44 must have been copying off of J-9 right? It predates Mig 1.44 for more than a decade.

You think I care if you want to make the Russians look bad for copying ?

The MIG-25 was a copy from the North American A-5 Vigilante, pal. Even the Soviets admitted it. You guys ignorantly believes that the F-15 was a copy and response to the MIG-25.

When it comes to technical issues, especially aviation, you PDF Chinese got nothing to go by.
