Recently, a piece of news about our domestic J-20 fighter has attracted widespread attention. According to Russia media reports, some Russian experts claim that the J-20 is actually copying their MiG-1.44, what J-20 key equipment is still bought from Maozi at a large price, and there are even defects ... As soon as these words came out, the controversy of military fans was ignited in an instant!
This has to start with the MiG 1.44. This is a verification machine made by the former Soviet Union in the 80s of the last century, which looks a little similar to the J-20, and many people believe in evil, thinking that the J-20 must be copied from others... As everyone knows, the truth is far from that simple!
Let's take a look at what the J-20 is like with the MiG 1.44? In terms of appearance, they do all have similar canard wings, large delta wings, and double hanging tails, and the silhouette feels quite similar. But if you look closely, the J-20 aerodynamic layout is so high that you don't know where it goes. What people are pursuing is hypersonic speed, stealth is not good, J-20 is all-round stealth, and the optimization of aerodynamics, stealth, and comprehensive performance is the peak, which is not a grade aircraft.
Besides, the MiG 1.44 is not a formed stealth fighter at all, and many of the key features that should be there are none, such as a built-in magazine, a vector nozzle, or something, but the J-20 has a lot of these must-haves, and the stealth performance is directly catching up with the F22, how can the MiG 1.44 be compared? Even India did not look at it back then, preferring to play with the Su-30 with Maozi, how could Chinese researchers be interested in this thing.
From beginning to end, the J-20 is the result of independent research and development from scratch. As early as the 90s of the last century, Professor Song Wencong began to explore the aerodynamic layout of China's fifth-generation aircraft, and proposed a small aspect ratio wing, DSI air intake, and canard wing layout, laying the design foundation for the J-20. Chief designer Yang Wei later inherited the mantle, and he was the world's top master in the writing of the duck layout flight control. The core technology of the J-20 has nothing to do with Maozi at all.
Some people say that the J-20 uses Maozi's engine, but that doesn't prove anything. Using an engine is plagiarism, and more than half of the world's fighters have long been plagiarized. The key core technology is your own is the real material. Now the AL31 has been replaced with a domestic Taihang engine, and the last trace of Maozi is gone. Besides, in addition to the J-20 using an engine, are there key technologies such as stealth and information fusion?
As for why China spends 500 million yuan to buy Maozi's key equipment, it is even more nonsense. This amount of money is not even a fraction of the money in the military-industrial system. The core of J-20 independent innovation is not something that money can buy. Besides, Maozi's technical reserves are really not necessarily stronger than ours.
What's more, some people insist on giving the J-20 a "design flaw" hat, what canard wings and main wings are inconsistent in height, and the radar signal increases balabala. It's really drunk, the canard wing originally has two roles: lift and handling, and it needs to be weighed in design, and it's normal not to be in the same plane. Besides, there is a DSI inlet tract, and the frontal RCS is well controlled.
So in the end, I would like to ask: What do you think about a project that was abandoned by yourself, taken by Chinese researchers, and developed such an advanced fighter as the J-20?
