Chapter 630 of the main text of the Eagle Flying Nine Heavens Chapter 630 of the Invisible! Invisible! Z-1 Fighter! First Kiss, this is a mysterious and special existence, which only exists between the two people who fell in love for the first time. It is both awkward and beautiful, and it is both sacred and solemn.

Especially for two people who are only 20 years old.

Most importantly, dozens of meters away, the founder of the motherland of the white sculpture quietly stared at the two of them and witnessed it, which was of great significance.

Put down all your identities and burdens, and hug each other and kiss each other.

Twenty years old in love,

Should be youthful and lively,

If it is sweet and greasy,

It should be carefree,

It should be intimate, not disturbed by identity, and do not care about other people's opinions or opinions.

The touch was lightly, as if it was electric shock, causing the two of them to tremble.

I have no experience in kissing, not skilled, awkward, but very happy, happy, and satisfied.

A soft and pleasant feeling, like a clear trickle, constantly hitting the mind and warming into the heart. Zhou Hai also felt a faint sense of red wine.

However, in just a few seconds, Zhou Hai's face turned shamelessly red, and the girl in her arms breathed slightly faster.

After a long time, kissed.

"Uh, this, I..."

Zhou Hai scratched his head and looked at Zuo Xue's red ears, his mind was like a fragment, and he didn't know what to say.

this,

this,

this,

Mom, how can I explain it when I have a physiological reaction?

"I've been playing almost today. I'm leaving. When I go back to the hotel, I'll show you something. The works I've designed during this period."

Zuo Xue's breathing was rapid, and she gave Zhou Hai a glance, without blaming her. After quickly calming down her inner emotions, she adjusted her slightly wrinkled white dress and pulled Zhou Hai up and walked back.

Zhou Hai was a little curious: "Work?"

"The aerodynamic layout and appearance design of the fourth generation main fighter jets, as well as the design concepts of several future fighter jets, are all original, of course, only based on my thoughts." Zuo Xue's words revealed a hint of pride.

"If possible, say something, and don't talk about confidential content."

Zhou Hai was interested, but wanted to see how this girl learned and whether she really understood the design concept and aerodynamic layout of the fourth generation stealth machine.

Can Zuo Xue, 20 years old, already study the fourth-generation aircraft?

Somewhat unexpected!

This girl is extremely talented and can observe the size of the gold group. She will never deny it. She is sure of this. The dazzling golden ball in her mind is as big as an egg, almost the same as Academician Yang Wei whom she saw at first, and even slightly beyond that.

However, being gifted with evil does not mean having the same strength.

Fourth generation machine!

Even Zhou Hai has never touched the most cutting-edge and cutting-edge fighter jet in the world today. He can only watch it up close, let alone driving experience.

"There is nothing confidential. Just as I created and played privately, I just made a concept sketch. At this stage, 2020 and the future belong to the stealth era. Stealth performance has become the most important performance indicator of a fourth-generation fighter under development. Stability perception capabilities are second, supersonic cruise and supermaneuver are third and fourth, based on Chengfei's two fighters, the J-20 and Shenfei Fc-31, I absorbed a certain degree of advantages and designed a new fourth-generation aircraft based on the core idea of ​​stealth."

Zuo Xue subconsciously looked around, and after confirming that there was no one, she leaned against Zhou Hai, staring at the star city with neon lights flashing under the dim sky, and slowly said the unsecret design content:

"Single-seat dual-engine heavy-duty aircraft, dual arches and vertical tails, aerodynamic layout adopts a medium trapezoid, candle wings are abolished, binary rectangular vector engines are used, and the wing body transition sections and arc transition areas on the left and right sides of the fuselage are eliminated. The radar reflection lobes are reduced to 7. If the manufacturing materials and stealth coating are consistent with the J-20, the initial estimate is that the stealth performance meets the design requirements, and the forward radar reflection cross-sectional area is estimated to be the same as the f22. However, the most helpless thing is that this fighter is similar to the aerodynamic shape of the mainstream fighter, and its maneuverability is not as good as the J-20, and the F-22 and Su-57, which is worse than the f-35."

At the end of the conversation, I felt helpless.

When talking about the latest works that gather the crystallization of his own wisdom and hard work, Zuo Xue can talk endlessly and say all these things.

Invisible!

The fourth-generation fighter ranks first and most critical performance indicators, no doubt.

Without stealth performance, even if it has super maneuverability, supersonic cruise, and superstable perception, it can only be reduced to the quasi-fourth generation level and can never cross the threshold of the fourth generation aircraft.

Regarding the strength of stealth, 80%-90% is determined by the overall aerodynamic layout, and 10%-20% is compensated by stealth paint. The wisdom and hard work of aircraft designers dominate.

It can also be called the magic of the wings!

In addition to stealth, the second-ranked situational awareness. The strength of air-based long-range detection and recognition capabilities of an enemy determines the combat performance and actual combat effectiveness of a stealth fighter. However, this is based on the hardware foundation. Without strong cutting-edge airborne radar and detection equipment, it is simply unable to meet the requirements.

"Forward stealth and mobility are both equal to f-22?" Zhou Hai glared, a little as he smacked his tongue.

The girl is not simple, she seems to have really understood it?

Reduced radar lobes, typical outsourcing double vertical tails, single seat and double engines, mid-section trapezoidal wing design, and the binary rectangular vector engine that best suits stealth performance.

This fighter does not emphasize maneuverability, but only focuses on stealth, gradually amplifies and strengthens it, playing the role of stealth as the king, and performing the most core "kicking the door" mission in modern warfare.

In the darkness, a thousand miles of raid will be killed with one blow.

The enemy died until he died, and he didn't know how he died!

Zuo Xue raised her proud little head slightly: "Of course, as the world's first stealth fighter, the f-22 has many things worth learning from and reference from the field of aircraft design and aerodynamic appearance, and is also the first and most important challenge object. If the performance of the new fourth-generation aircraft is not to be on par or surpass the f-22, what is the significance of designing a new fighter?"

At the same level as both sides, the concept and significance of weapon design is to be stronger than or equal to the opponent, weaken their performance advantages, and enhance their own chances of winning the war.

What's the point of developing a backward weapon without taking this concept as the core?

Waste of time and resources.

In addition, when designing a new weapon, we must also pay attention to timeliness, fully consider the various situations encountered in war, conform to the core design ideas, be close to reality, and be strict and cautious.

Take fighter jets as an example. Shenfei's J-11b was lagging behind as soon as it was developed and could not keep up with the mainstream development of the times.

"Does your work have a name?" Zhou Hai smiled and held Zuo Xue's shoulder and said curiously.

"Yes, I named it z-1. You are Zhou, I am only left, and I take the first letter of my surname. Unfortunately, this is just a concept design, and it is somewhat idealistic. In addition, I will cancel the canard. If you want to actually develop it, you will probably have to go in more than ten years." Zuo Xue said.
