The first kiss is a mysterious and special existence that only exists between two people who fall in love for the first time. It is raw and beautiful, sacred and solemn.
Especially for two people who are only 20 years old.
The most important thing is that dozens of meters away, the white sculpture of the founder of the motherland quietly stared at the two people and witnessed it, which is of extraordinary significance.
Let go of all identities and baggage, hug each other and kiss.
Love at the age of twenty,
When you are young and lively,
When it is sweet and sweet to the heart,
Be carefree,
It should be intimate, uninterrupted by identity, and no need to care about other people's eyes and opinions.
The gentle touch felt like an electric shock, causing both of them to tremble.
The kisser had little experience, even less proficiency, and was jerky and clumsy, but he was very happy, happy, and satisfied.
A soft and comfortable feeling, like a clear trickle, continuously hits his mind and warms his heart. Zhou Hai also feels a faint hint of red wine.
However, within just a few seconds, Zhou Hai's face turned shamefully red, and the girl in his arms began to breathe slightly faster.
After a long time, we kissed.
"Uh, well, I..."
Zhou Hai scratched his head and looked at Zuo Xue, whose ears were red and hot. His mind seemed to be fragmented and he didn't know what to say.
this,
this,
this,
Oh my god, I have a physiological reaction. How to explain it?
"We've almost finished playing today. Let's go. When we go back to the hotel, I have something to show you. The works I designed during this period."
Zuo Xue breathed rapidly and glanced at Zhou Hai without blaming her. After quickly calming down her inner emotions, she straightened out her slightly wrinkled white dress and pulled Zhou Hai back.
Zhou Hai was a little curious: "Work?"
"The aerodynamic layout and appearance design of the fourth-generation main fighter, as well as several design concepts for future fighters, are all original. Of course, they are based only on my ideas." There was a hint of pride in Zuo Xue's words.
"If you can, tell me. I won't talk about confidential information."
Zhou Hai became interested and wanted to see how this girl was doing and whether she really understood the design concepts and aerodynamic layout of the fourth generation stealth machine.
20-year-old Zuo Xue is already able to research fourth-generation aircraft?
Somewhat unexpected!
This girl is extremely talented and can observe the size of Zhou Hai's golden group. She will never deny it. She can be sure of this. The dazzling golden ball in her mind is as big as an egg, which is the same as the one she saw at first sight. Academician Yang Wei is almost unanimous, and even slightly exceeds it.
However, being a talented monster does not mean having the same strength.
Fourth generation machine!
The most cutting-edge and cutting-edge fighter aircraft in the world today, even Zhou Hai has never touched it once. He can only watch it up close, let alone the driving experience.
"There is nothing confidential. I am just creating in private. I just made a concept sketch. At this stage, 2020 and beyond belong to the era of stealth, and stealth performance has become the most important performance of a fourth-generation fighter under development. Indicators, situational awareness are second, supersonic cruise and super maneuverability are third respectively, fourth, I am based on Chengdu Aircraft’s J-20 and Shen Fei FC-31 fighters as prototypes, absorbing a certain degree of advantages, and based on stealth The core idea is to design a new fourth-generation machine.”
Zuo Xue subconsciously looked around, and after confirming that no one was there, she leaned against Zhou Hai, staring at the star city with flashing neon lights under the dim sky, and slowly said the design content, which was not confidential:
"A single-seat twin-engine heavy-duty aircraft with twin cambered vertical tails. The aerodynamic layout adopts a medium trapezoid, cancels the canards, uses a binary rectangular vector engine, and eliminates the transition section of the wing body and the arc transition areas on the left and right sides of the fuselage. Radar The reflection lobes are reduced to 7. If the manufacturing materials and stealth coating are consistent with the J-20, the stealth performance is initially estimated to meet the design requirements. The forward radar reflection cross-section is estimated to be the same as the F22. But the most helpless thing is that this fighter is comprehensive The aerodynamic appearance is similar to that of mainstream fighters, but its maneuverability is not as good as the J-20, on par with the F-22 and Su-57, and better than the F-35."
At the end of the sentence, I felt a little helpless.
When talking about the latest works that are the crystallization of her own wisdom and hard work, Zuo Xue can be said to be endlessly talking about all these things.
Invisible!
The fourth-generation fighter ranks first and most critical performance indicator, bar none.
Without stealth performance, even if it has super maneuverability, supersonic cruise, and super situational awareness capabilities, it can only be reduced to a quasi-fourth-generation aircraft and will never be able to cross the threshold of a fourth-generation aircraft.
As for the strength of the stealth capability, 80%-90% is determined by the overall aerodynamic layout, and 10%-20% is made up by the stealth coating. The wisdom and hard work of the aircraft designer play a dominant role.
It can also be called, the magic of wings!
In addition to stealth, ranking second is situational awareness. The ability of space-based long-range enemy detection and recognition determines the combat performance and actual combat effectiveness of a stealth fighter. However, this is a hardware basis and does not have a powerful cutting-edge machine. Carrying radar and detection equipment is simply unable to meet the requirements.
"Forward stealth and maneuverability are both equal to the F-22?" Zhou Hai glared and smacked his tongue.
The girl is not simple, she seems to have really understood it?
Reduce radar lobes, typical cambered double vertical fins, single-seat twin engines, mid-section trapezoidal wing design, and a binary rectangular vector engine that is most suitable for stealth performance.
This fighter does not emphasize mobility, but only focuses on stealth. It gradually amplifies and strengthens it, playing the role of stealth as king, and plays the core "knocking down the door" task in modern warfare.
In the darkness, a surprise attack from thousands of miles away will kill you with one strike.
Even when the enemy dies, he doesn’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 referring to in terms of aircraft design and aerodynamic appearance. It is also the first and most An important challenge is that if the performance of the new fourth-generation aircraft is not aimed at equaling or surpassing the F-22, then what is the point of designing a new fighter?"
When both sides are at the same level, the concept and significance of weapon design is to be stronger than or equal to the opponent, weaken its performance advantage, and improve one's own chances of winning the war.
If we don't take this concept as the core, what's the point of developing a backward weapon?
Waste of time, waste of resources.
In addition, when designing a new weapon, we must pay attention to timeliness, fully consider various situations encountered in war, conform to the core design ideas, and be close to reality and be strict and cautious.
Take fighter jets as an example. Shenyang Aircraft's J-11B fell 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 asked curiously, smiling and holding Zuo Xue's shoulders.
"Yes, I named it Z-1, you are Zhou, I only left, and named the first letter of the last name. Unfortunately, this is just a conceptual design, a bit idealistic, and the canards are cancelled. If you want to actually develop it, it will probably take a long time. Let’s go more than ten years later.” Zuo Xue said.
