You must know that the reason why the fourth-generation fighter can beat the third-generation fighter in the future is that one of the most prominent performance is stealth, which is like two martial arts masters, the third-generation fighter has nothing to say about the leg and foot skills, but in the face of the fourth-generation fighter with internal strength, even the corners of people's clothes can't be touched, and they are shocked into internal injuries.

The key to the stealth of the fourth-generation fighter is still in the material, not only to refraction the radar, but also to absorb a part of the radar wave to attenuate, the two are superimposed, even if the detected radar wave is not completely canceled out, the energy efficiency will be sharply reduced by half.

This is enough for fighters, because whether it is an enemy fighter or an air defense system, the effectiveness of the detection radar is halved, which is equivalent to saying that a fist that could hit a hundred kilometers can now only hit fifty kilometers.

In this way, as long as your fighter plane is 60 kilometers away from the opponent to attack, it can knock out the opponent 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 detect radar waves with obvious specular reflection or absorption effect, can only be combined with expensive absorbing coatings, combined with angular scattering aerodynamic layout to complete the so-called "stealth" effect.

For example, the American F-117 is a representative of this stealth function.

The effect is not to say, and the performance is okay, but the cost of this aircraft is expensive, and the maintenance cost is also outrageously high, especially the stealth coating on the surface of the fuselage, which is called a gold expensive, it is not hot, cold, and there is too much moisture, it is simply a nightmare for logistics maintenance.

If you want to fundamentally solve this problem, you can only work materials, and carbon fiber composite materials, which have been gradually widely used in the field of aviation manufacturing, are a good carrier.

Because its essence is a fabric made of thread, other properties can be added to it, such as Song Yanan's accidental discovery that the metal wire forms a microscopic refraction effect inside the material, so as to achieve the characteristics of overall specular reflection.

By analogy, if some materials with electromagnetic wave absorption properties are added, will it partially shield the irradiated radar waves?

If absorption and specular refraction are applied at the same time, then to what extent will this material reach in terms of radar stealth?

If we dig a little deeper and achieve a balance of strength, toughness and structure of this new carbon fiber composite, will it be possible to reduce the use of expensive absorbing coatings and thus improve the maintainability of stealth fighters?

At that time, Zhuang Jianye, who was holding a technical briefing, could be described as imaginative, no way, if this scientific and technological speed tree could be lit up, let alone catch up with the world's advanced aviation-grade carbon fiber composite materials, it would be easy to achieve corner overtaking.

This thing not only has to be done, but also has to be done in a big way, and the key projects of the "Seventh Five-Year Plan" have to be begged even if they go to the ministries and commissions to kneel and beg.

As a result, Song Yanan had a big belly, and he didn't ask for anything, so he didn't say anything about it, and Song Yanan had to be dealt with.

There is no plan or anything, Zhuang Jianye gritted his teeth and can still hold on, he has been like this in the past few years, and Zhuang Jianye doesn't care, but if Song Yanan is dealt with, not to mention the carbon fiber composite materials that have made great progress, even the stealth materials that have just had eyebrows will die directly.

That's a lot of loss.

In addition, Peng Chuan, an aviation machinery expert, is inseparable from the equipment transformation in the factory, the research and development and assembly of special equipment, and the transformation of numerical control.

Therefore, Zhuang Jianye simply ran to the capital by himself, squatted at the door of the office building of the ministry and commission, and when he saw a main leader coming out, he leaned on without skin and face, first took two bags of salted duck eggs from Huancheng, and then said with tears and snot that it was not easy to take off the factory, and by the way, he reviewed his negligence in implementing family planning work, and finally went straight to the topic to ask the leaders to let go.

After working so busy for almost half a month, he finally annoyed the leaders of several ministries and commissions, called Zhuang Jianye over to criticize him, instructed him to conscientiously implement the family planning work in the whole plant, and signed a letter of responsibility with the ministries and commissions.

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 removed from the title of researcher of the Materials Institute of Xihang.

It was lifted high and gently put down, which did not affect the existing work of the two.

As a result, the two parties did not expect that they should know that the family planning policy is almost a red line of who touches and who dies, and the two of them are also psychologically prepared, and they will accept punishment if they can't do it.

For this reason, Peng Chuan was ready to go home to farm, while Song Yanan was simply ready to go abroad and start over.

Unexpectedly, their factory director actually took the responsibility and went to the capital to help them exonerate, but in the end they just got a punishment that was not light or severe, and in the face of the punishment of fines of tens of thousands of yuan and dismissal from public office, it was like a spring breeze, and it was so light that it was simply negligible.

But because of this, needless to say, the gratitude of the two to Zhuang Jianye is needless to say, Peng Chuan directly used his actions to show that working overtime is more crazy than before.

As for Song Yanan, after receiving his notice of dismissal from Western Airlines, he asked Zhuang Jianye for a badge of the Tengfei factory, and he never took it off again for the rest of his life.

For the sake of talents, Zhuang Jianye would rather push the plan back, but when the cold came, Zhuang Jianye did not have the ability to push the illness away.

Speaking of which, I didn't pay attention when I was in the capital, I was cold, and when I returned to Huancheng, the cold and heat alternated, and the severe cold came up directly, otherwise there were so many things at the end of the year in the factory, how could he, the principal, still sleep under the quilt at home.

It's not that I don't want to go, but I feel uncomfortable all over my body when I move...... Damn......

As soon as Zhuang Jianye sighed in his heart, a sneeze erupted uncontrollably.

Fortunately, Zhuang Jianye lifted the quilt in time, otherwise tears and snot would have sprayed into the quilt, but even so, his clothes were still damaged, and he had no choice but to wipe them with a handkerchief.

He was busy working here, when he heard someone outside the living room ask, "Is Director Zhuang awake?"

Then I listened to my wife's voice: "I've been asleep for two hours after taking the medicine, I should be up, you sit down first, I'll go in and have a look." ”

Before the words fell, I heard the sound of getting up, and then the bedroom door was opened, Ning Xiaohui almost laughed when she came in, and quickly took out a handkerchief to help Zhuang Jianye sort out his clothes: "How old is it, how can you be the same as Xiao Dudu, and your snot can still get on your clothes." ”

Xiao Dudu is Zhuang Jianye's daughter, her father was sick, and she was afraid of infecting her daughter, so she was sent by Ning Xiaohui to her grandfather Ning Zhishan, but with Zhuang Jianye's cheekiness, this ridicule is nothing at all, hehe smiled, and snorted outside: "Who is here?"

"Director Song's lover, I heard that you were sick, so I came to see you!"

Saying that, Ning Xiaohui handed Zhuang Jianye a look that you know, Zhuang Jianye naturally understood that he stepped on the red line and was saved, which was thanked by people by taking advantage of his illness.

So this bed is not a good thing, so I can only get up and dress, come to the living room to meet Song Yanan's lover, know it politely, and talk about some local anecdotes in Huancheng, Song Yanan's lover changed his words and said something that shocked Zhuang Jianye:

"Director Zhuang, I heard that the civil aviation side is preparing to stop the cooperation with Tengfei Factory, I don't know if you know about it?"
