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.
Russians are very fond of showing off, but they are uncharacteristically afraid to show the su57 internal weapon rack. In order to reduce the air pressure, a gap is left in the weapon door of su57, although this will destroy the stealth capability.
Obsonov, general manager of Russian Tactical Missile Weapons Group, also admitted frankly that su57 could not launch aam for the time being, but could only launch heavy cruise missiles at low speed.
The layout of central lifting body is the housekeeping skill of su27, but it is the cancer of su57. It makes the stealth design of su57 inherently flawed, and it makes it difficult to design the weapon rack inside su57. So Orders for su57 are scarce and the progress is slow.
The design of su75 is very good, if it can be mass-produced smoothly.The design level of su75 is much higher than that of fc31 in Shenyang and F35 . It gives medium stealth fighters a Dog fight missile.
Su57 can only use external weapon racks for new aam experiments.

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 ImageImageImageImage
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. ImageImageImageImage
The third step is to use the S-shaped curved inlet to shield the engine, because the exposed engine seriously damages the stealth capability.Only su57 has no such design, and its engine is obviously exposed. ImageImageImageImage
