this narration is wrong

Chapter 208 Benefit Distribution
After Director Liu hung up Guo Yuan's call, he opened the drawer and took out a black satellite phone.

After the call was connected, Director Liu quickly explained the situation without saying a word.

After listening to the other end, they just asked Guo Yuan and Zhang Yufei what their company names were before hanging up.

Both Guo Yuan and Zhang Yufei received calls from their superiors that afternoon.

After the people above confirmed that the main developer of this metal was Zhang Yufei, they directly dispatched a helicopter to pick up Zhang Yufei.

It's normal for the top to move so fast.

As Director Liu thought before, the key to seizing the initiative in modern warfare is air combat.

Stealth fighters are crucial to gaining the initiative in air combat.

For now, the invisibility of stealth fighters means low detectability.

At the current level of technology, radar waves are the most commonly used and most reliable means of long-distance detection. Therefore, so far, stealth technology refers to reducing the detectability of radar.

As long as the reflection level of radar waves is reduced to the same level as the surrounding environment, the equipment can be considered to be invisible to radar.

Not to mention professionals, even the majority of netizens are basically clear about this.

Like the classic question before: Why can I still see the stealth fighter when it is invisible? Most people know the answer.

Now I am afraid that this problem will only be seen in the mentally handicapped bar.

Speaking of stealth fighters, for aircraft, the sky is too open. Unless the reflection level is reduced to the level of clouds, it is difficult to avoid radar detection. Therefore, the development of stealth aircraft is extremely difficult.

At present, there are only a handful of aircraft that can truly be called stealth in the world.

At this stage, the stealth means of stealth aircraft mainly rely on the following two methods:
One is to use materials that can absorb radar waves. In fact, materials that meet this characteristic have been widely used in the manufacture of aircraft. Many classic models are made of this material. This material is wood.

Stealth wouldn't be a problem at all if the wood wasn't strong enough to make a high-speed fighter.

Modern fighter planes all use metal skin, which is like a shining mirror in front of radar waves. The only solution is to paint the fuselage with a special layer of material that can absorb radar waves, just like a submarine laying anechoic tiles. The first kind of coating is light-shielding material.

However, the paint will increase the weight of the aircraft and reduce the flight performance, and the second is that it will be worn and repainted from time to time. Therefore, the maintenance of stealth aircraft is much more difficult than that of ordinary aircraft.

The second way is to modify the design of the fuselage shape to reduce reflectivity in most directions.

Although the streamlined fuselage has low air resistance, it is like a convex mirror, no matter which direction the radar waves come from, it can be well reflected back.

Make the airframe as flat as possible, which can reflect most of the radar waves to other directions, indirectly reducing its own reflectivity.

For example, in F117, there is no curved surface on the whole body. At the same time, the inclined vertical tail is also in line with the stealth design.

The B2, which was hyped before, directly cancels the vertical tail.

Of course, metal skin is not the only thing that can reflect radar waves. The cockpit and the heat exhausted by the aircraft are good sources of reflection. Therefore, the cockpit glass of a stealth fighter must also be special glass that can block radar waves. Aircraft are no longer chasing extreme speeds.

This is how our J-20 achieves "invisibility".

The J-20 pays more attention to the pursuit of reducing the radar reflection cross-sectional area in terms of shape design. For example, the parts of the fuselage refuse to be arranged vertically, and try to eliminate smooth transitions, and there are no obvious protrusions, etc. The purpose is to make the scattered signal deviate from the Radar trying to pick it up.

Then there is the material. The fuselage of the J-20 is coated with a black stealth coating. This coating is an anti-passive detection coating with a very high light-shielding rate.

Zhang Yufei disappeared for 3 days, and Guo Yuan has been paying attention to the situation of Zhang Yufei's company for these 3 days.

On the morning of the fourth day, Zhang Yufei came back, and he came to Future Technology immediately.

Guo Yuan and Zhuge Chuang received him in the office together.

"Yufei, you are back." Zhuge Chuang couldn't help sighing after seeing Zhang Yufei.

"It's not like I'm going to do something bad, I will definitely come back." Zhang Yufei said with a smile.

"That's right! Brother Chuang, your worries are unfounded." Guo Yuan said.

"Chuangzi, let's catch up on the past in a while. Let me talk about the business first. Mr. Guo has already granted me the patent." Zhang Yufei handed a document to Guo Yuan.

Guo Yuan took the file and quickly browsed through it.

Soon Guo Yuan discovered that the authorized things on the document seemed to be different from what Zhang Yufei researched.

[This is the same as the third version of Star Engine. 】

After listening to the narration, Guo Yuan suddenly realized.

"Mr. Zhang, congratulations." Guo Yuan said while handing back the document to Zhang Yufei.

"There is nothing to congratulate, I am really pure luck this time."

"Luck is also a part of strength. How does President Zhang plan to use this patent?"

"The higher-ups helped me contact DJI, and our company will supply them with this material in the future, which can be regarded as a stable income.

Other than that, the rest is up to us.

Mr. Guo, I think so. The two of us will register a company together. I will pay for the patent and you will pay for it. At that time, the patent will be placed in the name of this company. We will split the income in half. I will not participate in the operation of the company. , as long as the accounts are transparent to me, what do you think? "

[I can promise that this kind of cooperation is equivalent to Rongyang Technology as long as it has the right to dividends and account supervision, and the patent is already yours in a sense. 】

After listening to the narration, Guo Yuan nodded in agreement, and handed over the matter to Zhuge Chuang.

Things were settled, Guo Yuan didn't hide anything from Lin Yumo anymore, and told her about it at night.

Lin Yumo was very surprised when she heard the words. She didn't expect a small company invested by Guo Yuan to come up with such a thing.

65% of the light resistance is still metal, which can be used as the metal skin of a fighter jet.

No wonder Zhuge Chuang had to be so cautious before, this kind of thing really needs to be more careful.

"Guo Yuan, you made a lot of money! Light-shielding materials, aside from military applications, have a wide range of civilian applications. With such a company, it can be regarded as knocking on the door of industry. Didn't you develop into industry in the future? Any idea? This company is just a foreshadowing." Lin Yumo said with a smile.

Guo Yuan nodded. He also thought so. This company can be regarded as the "vanguard" related to the future development of technology and industry.
