Chapter 296

You should know that the most outstanding performance of the fourth generation fighters in the future is stealth. It's just like two martial arts masters who have no leg and foot skills of the third generation fighters, but when they face the fourth generation fighters with internal skills, if they can't even touch other people's clothes, they will be shocked into internal injuries.

The key to stealth of the fourth generation fighter is the material, which can not only refract the radar, but also absorb part of the radar wave to make it attenuate. If the two are combined, the detected radar wave will be greatly reduced even if it is not completely offset.

This is enough for fighter planes, because whether it is enemy fighters or air defense systems, if the detection radar efficiency is halved, it means that it can only hit 50 kilometers when it used to hit 100 kilometers.

In this way, as long as the fighters of our side attack 60 kilometers away from the other side, they can knock down the other side unconsciously.

If it is combined with the advanced stealth aerodynamic layout, the stealth efficiency will be doubled. Of course, this premise is a breakthrough in stealth materials.

Because of its unique interest, most of the traditional metal materials, except for a few radioactive materials, can not have obvious specular reflection or absorption effect on the detection of radar wave, so they can only cooperate with expensive absorbing coating, combined with angular scattering aerodynamic layout to achieve the so-called "stealth" effect.

For example, the F-117 of the United States is the representative of this stealth function.

The effect is not obvious, and the performance is fairly good. However, the cost of this kind of aircraft is exorbitant, and the maintenance cost is also exorbitant. In particular, the stealth coating on the body surface is expensive. It's too hot, too cold, and too much moisture. It's a nightmare of logistics maintenance.

If we want to solve this problem fundamentally, we can only work hard on materials. Carbon fiber composite, which has been widely used in aviation manufacturing, is a good carrier.

Because its essence is a fabric made of thread, other properties can be added to it. For example, song Yanan accidentally found that the metal wire formed a micro refraction effect inside the material, so as to achieve the overall specular reflection.

By analogy, if you add some materials with the properties of absorbing electromagnetic waves, will the irradiated radar waves be partially shielded?

If absorption and specular refraction are applied at the same time, what degree will this material achieve in radar stealth?

If we dig deeper to balance the strength, toughness and structure of this new type of carbon fiber composite, is it possible to reduce the use of expensive absorbing coatings and improve the maintainability of stealth fighters?

At that time, Zhuang Jianye, who was holding a technical briefing, was full of imagination. There was no way. If he could light up this scientific and technological speed tree, let alone catch up with and surpass the world's advanced aviation grade carbon fiber composites, it would be easy to overtake on the curve.

We should not only do this, but also do it in a big way. For the key projects of the "Seventh Five Year Plan", we have to go to the ministries and commissions to ask for them.

As a result, song YA'NAN has a big stomach and has nothing to ask for. He has to deal with song YA'NAN even if he refuses to say one vote.

There's no plan. Zhuang Jianye can still hold on with his teeth. He doesn't care about the past few years. But if song Yanan is dealt with, not to mention the carbon fiber composite, which has made great progress, but the new invisible material will die.

That's a huge loss.

In addition, Peng Chuan, an aviation machinery expert, can't do without him for the equipment transformation in the factory, the R & D and assembly of special equipment, and the numerical control transformation.

Therefore, Zhuang Jianye went to the capital and squatted at the door of the Ministry office building. When he saw a major leader coming out, he leaned up without skin or face. First he took two bags of salted duck eggs produced by Huancheng specialty. Then he said with tears and tears that it was not easy for the factory to take off. By the way, he checked his negligence in implementing family planning work. Finally, he went straight to the topic and asked for your leaders Let it go.

After nearly half a month's hard work, the leaders of several ministries and commissions were finally annoyed enough, and Zhuang Jianye was called in for criticism. He was instructed to seriously implement family planning work in the whole plant, and signed a letter of responsibility with the ministries and commissions. Only in this way can Zhuang Jianye's cheekiness be regarded as blocking it.

However, there is no heavy responsibility for Peng Chuan and song Yanan, but the admonition is unavoidable.

Peng Chuan was warned by the party, and song Yanan was relieved of the title of researcher in the materials Institute of Western Airlines.

It was raised high and put down gently, which did not affect their current work.

As a result, the two parties did not expect to know that the family planning policy is almost the red line of who touches who dies. They are also psychologically prepared to accept punishment if they really can not.

For this reason, Peng Chuan is ready to go home for farming, while song Yanan is ready to go abroad and start again.

Unexpectedly, their factory director took the responsibility and went to the capital to help them escape. In the end, he just got a heavy punishment. In the face of tens of thousands of fines and dismissal from public office, he was as light as a spring breeze.

But just because of this, the two people's gratitude to Zhuang Jianye goes without saying. Peng Chuan directly expressed his gratitude with actions, and those who worked overtime were more crazy than before.As for song Yanan, after receiving his notice of dismissal from Xi'an airlines, he asked Zhuang Jianye for a badge of a take-off factory, and he never took it off again for the rest of his life.

For the sake of talents, Zhuang Jianye would rather postpone his plan, but when a cold comes, Zhuang Jianye has no ability to push the disease away.

I didn't notice when I was in the capital. When I got cold, when I got back to Huancheng, I caught a bad cold. Otherwise, there were so many things going on in the factory at the end of the year. Why was he still sleeping at home with his quilt covered.

It's not that I don't want to go, it's that I feel uncomfortable when I move. Look at it? The snot and tears come down as soon as they are said My God

Zhuang Jianye's heart just came out, a sneeze out of control.

Fortunately, Zhuang Jianye lifted the quilt in time, otherwise his tears and nose would spray into the quilt. Even so, his clothes were still in disaster, but he had to wipe them with a handkerchief.

As he was busy, someone outside the living room asked, "is factory director Zhuang awake?"

Then he heard his wife's voice: "after taking the medicine, I've been sleeping for two hours. I should get up. Please sit down first and I'll go in and have a look."

The voice did not fall to hear the sound of getting up, and then the door of the bedroom was opened, Ning Xiaohui came in and almost laughed, quickly took out a handkerchief to help Zhuang Jianye tidy up: "how big a person, how to be like little Dudu, the snot can get on the clothes."

Xiaodudu is Zhuang Jianye's daughter. Her father is sick and she is afraid of infecting her daughter, so she is sent to her grandfather Ning Zhishan by Ning Xiaohui. However, Zhuang Jianye's cheekiness doesn't make fun of her. He laughs and says: "who's coming?"

"Director Song's wife, I heard that you are ill. I came to see you specially!"

With that, Ning Xiaohui gives Zhuang Jianye a look that you know. Zhuang Jianye naturally understands that he has been protected after stepping on the red line. This is thanks by others for coming over from his illness.

So this bed is too much to rely on, so I have to get up and dress. I come to the living room to meet song Yanan's lover. I know it politely and chat about some local anecdotes in Huancheng. Song Yanan's lover just changed the subject and said something that shocked Zhuang Jianye: "director Zhuang, I heard that civil aviation is going to stop cooperating with Tengfei factory. I don't know Do you know? "
