Why can't India imitate the J-20? A sentence from Tsai Cheng-yuan made Europeans and Americans very desperate!
Why is the J-20 stealth fighter frequently appearing, not only increasing in numbers, but also continuously upgrading its avionics system and engine performance. However, the Indian Air Force is still troubled by the "indigenous fifth-generation fighter" project that has not been launched yet.
Western media are also confused: as two major Asian countries, why can't India produce its own J-20? In fact, a sentence from commentator Tsai Cheng-yuan really hurt the West: "China is solidly developing materials and aerodynamics, while India is just buying various components and assembling them."
Why did the West feel so hurt? Obviously, they hoped China would follow India's path. The West is most unwilling to see China make progress in fundamental disciplines such as physics and mathematics. A 2022 report pointed out that China's output and citation volume in mathematics, materials science, and engineering have all ranked first in the world. This accumulation of basic capabilities is the foundation for breakthroughs in the J-20, electromagnetic catapult technology, and hypersonic weapons.
Take the medium-voltage direct current integrated power system as an example, which is the core of China's ship-based electromagnetic catapult technology. Its theoretical basis involves highly mathematical fields such as nonlinear control and power electronics topology optimization - without solid theoretical training, it is impossible to achieve engineering conversion.
India has long followed the "assembling route". Its "Tejas" fighter took 33 years to enter service, during which it changed four types of engines and three sets of avionics systems, but could still only perform limited air superiority missions. Eventually, it crashed in front of everyone's eyes at the Dubai Air Show.
