What is stealth technology?The first step of stealth technology is that it must conform to the principle of parallel design,In order to reflect electromagnetic waves in another direction,This is only the first step in stealth technology. #Aircraft #Fighter #F22 #F35 #J20 The second step of stealth design is to design the edge and transverse gap of the wing in zigzag shape, and use radar wave absorbing materials.This is to deal with the diffraction phenomenon of radar waves.Only su57 has no such design.

Before, we explained the defects of the stealth capability of su57 in detail. Now, let's talk about another defect of su57, that is, the internal weapon rack.The aerodynamic shape of Central lifting body is a classic work of Sukhoi Company.But the problem lies in it. #F22 #F35 The layout of the central lifting body turns the groove in the middle of the engine into wings, which increases the lift of the fighter.However, the air pressure in this area is very high, and su34 once had the phenomenon that missiles hit its own airframe.
