What kinda bullsh!t is the OP trying to convey? Whether Chinese planes are 'cloned' or 'derivatives', the fact remains that these are basically a Russian design concept. Period!
So don't clutch at straws trying to prove the non existent Chinese 'expertise' in concept design! The Chinese are copycats and that's the bottom line!
Cheers!
So the did Japanese copy the car. Is Toyota a copy of European cars?
Everyone copies.
You copy and you build on that to improve it. Therefore you have a starting base.
China used the Russian airframe and installed everything else domestically overtime.
That is a domestic aircraft.
China can now produce this without getting approval from anyone or sell the fighters to anyone.
Yes the airframe is russian design, everything else is domestic Chinese technology.
We have our own domestic industry, now we reverse engineered it, found out all the things we needed to find out and now we don't need them anymore.
We are now becoming self sufficient in many areas.
India has zero domestic industry, you need significant talent to reverse engineer, if you can't then you must innovate from scratch wasting R&D. India cannot innovate and it don't have the ability to reverse engineer. What's the result of it.....IMPORT EVERYTHING.
Trust me, if India knew how to reverse engineer, they would do it in an instant, the problem is, reverse engineering is not easy, you need expertise and know how to improve upon it.
First you imitate then you innovate.
Imitation is the first step to innovation.
You learn from imitation to build your own industry.
