Ubiquitous trapezoidal faces and stealth detailing.

The 28.5 degrees of camber of the twin vertical tails has been carefully calculated, which seems to be ordinary, but it is delicate and natural, which reduces the radar reflection lobe surface and suppresses the radar irradiation signal received and reflected from the end of the fuselage.

The binary rectangular vector nozzle at the end of the fighter has the same stealth effect as the F-22, greatly eliminating the radar reflection cross-sectional area and infrared cross-sectional area.

Carefully browsing and conceiving the initial blueprint of the Z-1 fighter's three-view structure on the first page, Zhou Hai was a little frightened, rigorous calculation data, overall stealth design and detailed stealth means in line with mainstream standard aesthetics.

Mean?

Mass goods?

With the aerodynamic design of this initial blueprint, it can crush the F-35 'Lightning' that was previously in contact with it, and become one of the world's top fighters, which is by no means comparable to ordinary people.

Because, just imagining that everyone will, when imagining the future, it is easy to conceive of what super-cutting-edge fighter jet will beat the F-22 "Raptor".

Imagine the future, anyway, if you don't break the law, why not do it if everyone blows each other?

However, when it comes to aerodynamic design, airframe structure, wing type, aerodynamics, fluid mechanics, theoretical data and mathematical calculations, etc., 99% of people are blind and confused.

What is the theoretical basis of fighter stealth?

How to eliminate the radar reflected lobe surface?

How to suppress infrared radiation?

How to use the details of the trapezoidal surface while complementing the overall structure without problems?

How do you ensure that there are no conflicts when the details and the overall structure are integrated?

Will there be problems with the aerodynamic layout of the fuselage?

How to design the internal structure of the body?

These problems are only part of the development process of the new fourth-generation aircraft, and there are all kinds of problems that are so numerous that they need to be solved.

"I applied to use the supercomputer in the school to simulate and calculate the scattering surface and body structure of the stealth design of the Z-1 concept machine, and there are no major defects overall, but there are many problems in the details, after all, I still belong to the half-baked state of the fourth-generation aircraft design, if I continue to study and improve it in depth, it is preliminarily estimated that the Z-1 concept machine will meet the expected design performance indicators. In the face of the 2-meter wavelength of VHF radar, the stealth capability of the Z-1 is not ideal, the forward RCS is estimated to be more than 0.8 square meters, the quasi-fourth-generation level, and the L-band forward RCS is about 0.5 square meters, with the shorter the length of the electromagnetic threat wave source, the better the performance effect. ”

Zuo Xue rested his 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 RCS is 0.009 meters. ”

There's nothing more romantic than being alone with two people, leaning on the boy they like, and watching their elaborate creations together.

It's a beautiful feeling.

Of course, Zuo Xue, who is extremely professional, has all kinds of professional terms and nouns coming out of her mouth to ordinary people, like a book from heaven.

Supercomputing simulation?

Dabbler?

So this is the world of Xueba?

Hearing this girl's words, the corners of Zhou Hai's eyes twitched, he thought about it, and didn't speak.

Thinking carefully about the detailed radar reflected wave parameters analyzed by Zuo Xue, Zhou Hai fell into thought and continued to discuss and study the fighter: "Do you think the stealth effect of the F-22 can reach this height, will it be a little too high?" ”

At the same time, Zhou Hai can also listen to the future ideas and ideas of aircraft designers, and find the shining points, which may improve his combat effectiveness.

S-band, medium wavelength, frequency 1.55-3.4 Hz, mainly used for medium-distance air alert and target tracking.

The X-band, the main band area of the fire control radar and the target tracking and locking radar, with a frequency of 8-20 Hz, is used by the airborne fire control radar.

In the face of the X-band, the Z-1's forward radar reflection cross-sectional area can be reduced by 0.009 meters!

What is this concept?

In this conversion, the reflection cross-sectional area of 9 mm in the forward direction is only the size of a glass bead!

The detection range of radars above the high frequency band has plummeted to an incredible extent.

The well-designed Z-1 takes the world's first and most powerful F-22 'Raptor' fourth-generation stealth fighter as the reference target, Zuo Xue called it flat, so doesn't this mean that when the F-22 faces high-band radar, the forward reflection cross-sectional area is also only the size of a glass bead?

The cross-sectional area of glass beads seems to be nothing, and there is no concrete concept.

To give the simplest example, it is probably the world's mainstream level of the third-generation fighter, its air-based Doppler radar, when facing 9 mm glass bead-sized air targets, does not work, loses its original effect, can not lock on to the target in battle.

The whole situation is like a self-defeating martial arts, and even the active radar seeker of the fourth-generation medium-range bomb will fail!

The means of attack of third-generation fighters, in the face of such terrifying stealth performance, only infrared imaging combat missiles are useful.

But here's the problem, the fourth-generation aircraft with stealth performance is not a fool, and it may have friendly exchanges with you in non-war times, tearing each other apart, verbally mocking, and spying on intelligence, and will never show its true strength.

Once in a state of war, sorry, the fourth generation has the opportunity to make the most of the extremely high advantages given by stealth technology to carry out assassination raid tactics.

Supersonic cruise reaches the over-the-horizon strike range, locks on the target and kills with one hit, and then leaves quickly, and the whole process, the target being attacked is completely blind, without the slightest ability to change hands.

Ten steps to kill one person, thousands of miles without leaving a line, nothing more than this.

The impact of stealth performance on air combat is what the impact of radar on the air force and navy was in the past.

Countries in the world today that have a bit of capital, technology, self-motivation, and a sense of danger either choose to independently develop fighter planes, or strive to purchase fourth-generation aircraft, try their best to get along with stealth, catch up with the trend of the times, as if they do not have the mentality of being left behind without stealth, and the core reason for this is that the influence and combat effectiveness of stealth fighters are too terrifying.

In terms of maneuverability and combat performance, the Su-35 heavy aircraft and the F-22 may not be on par.

On real air combat, I'm sorry, the F-22, which fully exerts stealth performance, can solve 10 Su-35s with one plane, which is not alarmist, but true.

"It's not high, maybe it's not as good, this parameter is carefully analyzed and studied by my mentor and I, the stealth design of the F-22 is top-notch, and the stealth technology it applies is very advanced, even if it does not use DSI inlet technology, it is not outdated today."
