But strength is a problem!

So the materials must be changed.

If strong magnetic materials are not used, the levitation force will be weakened, but it should be fine. If it is not enough, you can increase the etching area.

wrong!

Also leave room for a balanced system.

When the wind speed reaches level 5, the force will reach 16000n.

That means that around 15000n is a critical value!

The area of ​​​​the robot balance system is about 0.3 square meters.

...

Now there is only one question left!

Confidential?

How should it be kept secret? Liu Chi thought about it. If it were etched onto the surface of the aircraft, the entire pattern would be equivalent to telling them!

Although they don't understand the principle and can't change it, they should be able to follow the gourd's pattern!

It seems that I still need to add some anti-counterfeiting features.

And this time the pattern cannot be made into a circle. It can be etched directly according to the shape of the wing, as close to the edge as possible.

Just when Liu Chi was thinking about how to prevent counterfeiting, Chen Luguang called.

"Old Chen, what's the matter?"

"Liu Chi, I have good news for you."

"What good news?" Liu Chi asked doubtfully.

"The application you applied for last time with me (Taihu Light) was approved."

"Really? That's great!" Liu Chi said in surprise, this is really good news.

"But you have too much material and it won't be finished for a while. It will probably take a while." Chen Luguang said.

"Okay, no problem, just let me know when you're ready."

"Okay!" Chen Luguang asked: "How to deal with (Light of Taihu Lake)?"

"You can help me arrange the production first. It will probably take two or three months. When I go back, I will see where it will be installed." Liu Chi thought for a while and said.

"good!"

"Is it just this one thing?"

"right!"

"Well, let's do this for now, I'm busy here."

"88."

...

Europe.

In a private room of a coffee shop.

A couple about 45 years old and a young man about 30 years old were sitting across from each other.

"Mr. Zhou, this is your daughter's information. You can take a look at it first, and we will talk about it later." The young man took out a portfolio from his bag and placed it in front of the couple.

"Okay!" Mr. Zhou picked up the file bag on the table, took out the documents inside, and slowly turned it over.

The lady next to me also leaned her head over.

Ten minutes later.

Mr. Zhou asked: "Can you tell me why you came?"

"You have also read the information. Your daughter Zhou Meng will become a key protector of our flower growers. So in order to prevent some people from using dirty tricks, I hope you will return to the country." The young man did not beat around the bush and said directly.

"Go home?" Mr. Zhou was surprised, and finally gave the young man a strange look.

"You should also know that here, sometimes we cannot provide effective protection, and our hands cannot reach that long."

"But we have changed our nationality." The lady next to me said, "Isn't it convenient to go back?"

"Ms. Jiang, don't worry, if you confirm your return to China, we will help you resolve the nationality issue," the young man promised.

"?"

"We will handle special matters." The young man saw the confused looks of the two people and said directly.

"Can you let us think about it?" The two looked at each other, and finally Mr. Zhou said.

"Okay." The young man nodded: "But it's best to go back as soon as possible before some people react. This can save a lot of trouble."

"good."

"If you decide, please contact me at any time."

"..."

After the young man left, Jiang Xueyue asked Zhou Mingjun: "Honey, do we really want to go back?"

"If the information I just read is true, I think we have no other choice. You should also understand the environment in Europe and the United States."

"Everything is decided by capital. We may really not be safe here." Zhou Mingjun said a little helplessly.

"Then go back. Anyway, I came out to cure my daughter's face. Now that my daughter's face has been cured, it's okay to go back." Jiang Xueyue thought and replied.

"Okay, it just gives me an excuse to go back." Zhou Mingjun nodded: "At least we don't have to worry about safety issues when we go back."

"Take care of the things at hand these days."

"good!"

"..."

Turn your attention back to the country.

Two days later!

Liu Chi took the information and found Hong Changtian, Zhang Zhi and others.

"Is it possible?" When Liu Chi communicated his ideas to several people, Zhang Zhi's first reaction was that it was impossible.

"..." Chen Jiahua, the deputy chief designer beside him, also looked at Liu Chi in confusion.

Hong Changtian took a few deep breaths of cool air!

It seems that I am on the right track this time!

Hong Changtian didn't doubt Liu Chi's words because he had seen the video of the robot levitating.

Now I didn’t expect Liu Chi to directly use this technology on this 21 aircraft. He suppressed the excitement in his heart and asked: "Teacher Liu, I would like to ask, if you want to etch so many patterns on the surface of the wing, how strong will it be?"

what to do?"

"This is why I came to you." Liu Chi nodded and said: "If it is traveling at Mach 3, the surface temperature of the aircraft should reach 200 degrees."

"How to ensure the strength of the wings, as well as flight resistance, etc., all of these must be considered. Otherwise, if the fighter plane falls apart at an altitude of more than 20,000 meters, it would be tantamount to murder."

"There is another problem. The patterns on the wings cannot be damaged. If damaged, the entire wing will have to be replaced."

Hong Changtian asked with some uncertainty: "Teacher Liu, do you mean that even a little scratch won't work?"

"Yes." Liu Chi nodded seriously.

"clear!"

"Then can we protect these lines?" Chen Zhi came back to his senses, thought for a while and asked.

"Protect it?" Liu Chi was stunned, looked at the design drawings in front of his computer, and then came back to his senses and asked: "Mr. Chen, do you mean double-layered?"

"Um!"

"If it is double-decker, the weather layout of the aircraft will change. Is that okay?"

"If Mr. Liu can really use the suspension method to change the aircraft from more than 30 tons to 15 tons, I think this problem should not be big." Chen Jiahua interrupted.

"What about the force-bearing layout? Are there any problems? And in terms of power, can it meet the requirements?"

"There should be no problem in terms of power. Even if we make the wings double-layered, the weight will only increase by about 2 tons at most."

Liu Chi thought for a while and said, "Let me take a look later." After speaking, he opened the computer in front of him, clicked a few times, and opened the aircraft design drawing.

I hit the keyboard with a bang.

The four people gathered around curiously.

Looking at Liu Chi's constantly moving data.

Ten minutes later!

"No!" Liu Chi stopped and finally shook his head.
