But strength is a problem!

So the material must be changed.

If you don't use strong magnetic materials, the suspension force will be weakened, but it should be fine. If it's not enough, you can increase the area of ​​the etching method.

wrong!

Also leave space for balancing the system.

When the wind speed reaches level five, the force will reach N.

That means N is a critical value!

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

......

Now there is only one question left!

Keep it confidential?

How should we keep it secret? Liu Chi thought about it. If the pattern was etched onto the surface of the plane, it would be like telling them the whole pattern!

Although they don’t understand the principles and cannot make changes, they should be able to copy them!

It seems that we still need to add a few anti-counterfeiting ones.

And this time the pattern cannot be made into a circle. You can directly etch it according to the shape of the wing, trying to get 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 puzzledly.

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

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

"But you have too many materials, and it will take a while to process them all. I guess we'll have to wait for a while." Chen Luguang said.

"Okay, no problem. Just let me know when you're done."

"Okay!" Chen Lvguang asked, "Then what should we do with (the light of Taihu Lake)?"

"Please help me arrange the production first. The production cycle is estimated to be two or three months. I will go back and see where to install it." Liu Chi said after thinking for a while.

"good!"

"Is that all?"

"right!"

"Well, that's it for now. I'm busy here."

"88."

......

Europe.

In a private room of a coffee shop.

A couple in their 40s and a young man in his 30s sat opposite each other.

"Mr. Zhou, this is your daughter's information. Please take a look at it first and we'll talk later." The young man took out a file bag 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 flipped through them.

The lady next to her also leaned over.

Ten minutes later.

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

"You have also read the information. Your daughter Zhou Meng will become a key protected person in our Flower-Growing Family. So in order to prevent the despicable means of certain people, I hope you can return to China." The young man said directly without beating around the bush.

"Return to China?" Mr. Zhou was surprised, and finally looked at the young man strangely.

"You should also know that here, sometimes we can't provide effective protection because we can't reach that far."

"But we have changed our nationality." The lady next to him said, "It's not convenient to go back, right?"

"Ms. Jiang, don't worry. If you confirm your return to China, we will help you solve the nationality issue." The young man assured.

"?"

"Special matters will be handled specially." The young man said directly when he saw the two people's puzzled looks.

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

"Sure." The young man nodded: "But it's better to go back as soon as possible before some people can't react. This way you can save a lot of trouble."

"good."

"If you decide, feel free to contact me."

"......"

After the young man left, Jiang Xueyue asked Zhou Mingjun, "Husband, are we really going back?"

"If the information I just saw is true, I think we don't have any other choice. You should also understand the environment in Europe and the United States."

"Capital has the final say in everything. We may not be safe here." Zhou Mingjun said a little helplessly.

"Then let's go back. Anyway, we came out to cure my daughter's face. Now that her face has been cured, there is nothing wrong with going back." Jiang Xueyue thought for a while and said.

"That's fine. We can use this as an excuse to go back." Zhou Mingjun nodded: "At least we don't have to worry about safety when we go back."

"Take care of the things on hand these few days."

"good!"

"......"

Let’s turn our attention back to the country.

Two days later!

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

"Is it possible?" After Liu Chi communicated his idea with several people, Zhang Zhi's first reaction was that it was impossible.

"......" Deputy Chief Designer Chen Jiahua next to him also looked at Liu Chi with a confused look on his face.

Hong Changtian took a few deep breaths!

It seems that I have taken the right path this time!

Hong Changtian did not doubt Liu Chi's words because he had seen the video of the robot floating.

I didn't expect Liu Chi to use this technology directly on the 21st aircraft. I suppressed my excitement and asked, "Teacher Liu, I want to ask, if you etch so many patterns on the wing surface, what about the strength?"

"That's why I came to you." Liu Chi nodded and said, "If it's at Mach 3, the surface temperature of the aircraft should reach 200 degrees."

"How to ensure the strength of the wings, the resistance of flight, etc., all these have to 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 pattern on the wing cannot be damaged. If it is damaged, the entire wing must be replaced."
