Trapezoidal faces and stealth details are everywhere.
The 28.5-degree cambered double vertical fins have been strictly calculated and appear ordinary, but are exquisite and natural, reducing the radar reflection lobe and suppressing radar illumination signals received and reflected from the end of the fuselage.
The binary rectangular vector nozzle at the end of the fighter jet has the same stealth effect as the F-22, greatly eliminating the radar reflection cross-section and infrared cross-section.
Zhou Hai carefully browsed and conceived the initial blueprint of the three-view structure of the Z-1 fighter on the first page. Zhou Hai was a little frightened when he saw the rigorous calculation data, the overall stealth design and detailed stealth methods that conformed to mainstream standard aesthetics.
Moderate?
Popular goods?
Just relying on the aerodynamic design of this initial blueprint, it can crush the F-35 'Lightning' that it has been exposed to before, and join the ranks of the world's top fighters, which is definitely not comparable to ordinary people.
Because, just by imagining, everyone can easily imagine what kind of super-sophisticated fighter jet can defeat the F-22 Raptor when they imagine the future.
Let's imagine the future. It's not illegal anyway, so why not let everyone brag about each other?
However, when it comes to serious aerodynamic design, airframe structure, wing type, aerodynamics, fluid dynamics, theoretical data, mathematical calculations, etc., 99% of people will be blinded and confused.
What is the theoretical basis of fighter aircraft stealth?
How to eliminate radar reflection lobe surface?
How to suppress infrared radiation?
How to use detailed trapezoidal surfaces while complementing the overall structure without causing problems?
When integrating the details and the overall structure, how to ensure that there will be no conflict?
Will there be any problems with the aerodynamic layout of the fuselage?
How should the internal structure of the body be designed?
These problems are only some of the problems encountered in the development process of the new fourth-generation machine. There are also a variety of mind-numbing problems that need to be solved.
"I previously applied to use the school's supercomputer to simulate and deduce the stealth design scattering surface and body structure of the Z-1 concept aircraft. There are no major flaws in general, but there are many problems with details. After all, I am concerned about the design of the fourth-generation aircraft. It is still in a half-baked state. If we continue to study and conduct in-depth research and improvement, it is initially estimated that the Z-1 concept aircraft has reached the expected design performance indicators. When faced with the 2-meter wavelength of the VHF radar, the Z-1's stealth capability is not ideal. The forward RCS is estimated to be more than 0.8 square meters, quasi-fourth generation level, and the L-band forward RCS is about 0.5 square meters. As the length of the electromagnetic threat wave source is shorter, the performance effect will be better."
Zuo Xue rested her head on Zhou Hai's shoulder and said: "The S-band forward reflection cross-sectional area is reduced to 0.08 meters, the C-band is reduced to 0.05 meters, and the X-band RC meters. Detailed parameters and basic performance parameters for the side and rear sides. The indicator is on the back of the first page, which is basically the same as the F-22 reflection area I analyzed."
There is nothing more romantic than two people being alone in a room, leaning against the boy they like, watching their carefully created works together.
This feeling is beautiful.
Of course, the various professional terms and nouns that come out of Zuo Xue's mouth, which is extremely professional, sound like a book from heaven to ordinary people.
Supercomputer simulation?
Half-assed?
So is this the world of top academics?
Hearing the girl's words, Zhou Hai's eyes twitched, he thought for a while and said nothing.
Thinking carefully about the detailed radar reflection wave parameters analyzed by Zuo Xue, Zhou Hai fell into thinking and continued the discussion and research on fighter aircraft: "Do you think the stealth effect of the F-22 can reach this level? Isn't it a bit too much?" Taller."
Discussion and research are beneficial to enhancing feelings. At the same time, Zhou Hai can also listen to the future concepts and ideas of aircraft designers and discover the shining points, which may improve his combat effectiveness.
S-band, medium wavelength, frequency 1.55-3.4 Hz, mainly used for mid-range air warning and target tracking.
The X-band, the main band area of fire control radar and target tracking and locking radar, has a frequency of 8-20 Hz. Airborne fire control radars all use this band.
Facing the X-band, the Z-1's forward radar reflection cross-section can be reduced by 0.009 meters!
What is this concept?
After conversion, the reflection cross-sectional area of 9 mm in the forward direction is actually only the size of a glass bead!
The detectable range of radars above the high band suddenly drops, shortening to an incredible level.
The carefully designed Z-1 takes the world's first and most powerful fourth-generation stealth fighter F-22 'Raptor' as a reference target. Zuo Xue calls it the same. So, doesn't this mean that the F-22 For high-band radar, the forward reflection cross-sectional area is also only as large as a glass bead?
The glass bead-like cross-sectional area seems to be nothing, and there is no specific concept.
The simplest example is probably the world's mainstream third-generation fighter aircraft. The air-based Doppler radar it carries does not work when faced with a 9 mm air target as big as a glass bead, and loses its original capabilities. Effect, unable to lock the target during combat.
The whole situation is like a self-defeating martial arts, even the active radar seeker of the fourth-generation medium-range missile will fail!
Among the attack methods of third-generation fighters, in the face of such terrifying stealth performance, only infrared imaging combat missiles are useful.
But here’s the problem. Fourth-generation aircraft with stealth capabilities are not fools. In non-war times, they may have friendly and affectionate exchanges with you, fight each other, verbally ridicule, and spy on intelligence. They will never reveal their true nature. strength.
Once it enters a state of war, sorry, the fourth generation has the opportunity to maximize the advantages given by stealth technology and execute assassination raid tactics.
The supersonic cruise reaches the over-the-horizon strike range, locks on the target and kills it with one strike, and then quickly leaves. During the entire process, the target being attacked is completely blind and has no ability to change hands.
Killing one person in ten steps and leaving no trace in a thousand miles is nothing more than this.
The impact of stealth performance on air combat is just like the impact on the Air Force and Navy when radar appeared.
In today's world, countries with some capital, technology, ambition, and a sense of urgency either choose to independently develop fighter jets, or strive to purchase fourth-generation aircraft, try to be as stealthy as possible, and catch up with the trend of the times. The core of this mentality is that if they do not have stealth, they will be left behind. The reason is that the impact and combat effectiveness of stealth fighters are too terrifying.
In terms of maneuverability and combat performance, the Su-35 heavy aircraft may not be comparable to the F-22.
When it comes to real air combat, sorry, the F-22 with its full stealth performance can defeat 10 Su-35s with one aircraft. This is not alarmist, but it is true.
"It's not high, maybe not as high. This parameter was carefully analyzed and studied by my instructor and I. The F-22's stealth design is top-notch, and the stealth technology it applies is very advanced. Even without the use of DSI air inlet technology, It’s not out of date today either.”
