Chapter 646 Must Be Serious (2/3)

For the structural change, Xu Mang didn't even need to conduct any experiments. There are a lot of useful data recorded in this research material, and it can be completed by making reasonable deduction based on some of the above data.

Of course...Xu Mang would not miss this opportunity to learn. From the entire information, he roughly knew the research process of metamaterials, which was indeed very different from the tradition.

insulation layer,

airtight layer...

Xu Mang took a look at the original design structure. He used a mutually focused nanoporous network structure, and filled the gaps with a highly dispersed solid material with a gaseous dispersion medium. In this way, the heat conduction and thermal conductivity of the material are well controlled. Gaseous convective heat transfer.

But... the atmosphere of Mars is less than 1% of that of the earth, and the surface atmospheric pressure is only 500 to 700 Pa. This design... To be honest, it has become a burden instead.

According to Xu Mang's calculation,

The thermal insulation design of the new structure airgel not only provides an ideal thermal insulation effect in a low-pressure environment, but the most important thing is to resist the 60G impact force that the aircraft must withstand during the launch phase and landing on the surface of Mars.

According to the general formula of Xu Yang's structure, a set of data was obtained, and Xu Mang roughly got an ideal structure. This structure was honeycomb-shaped, but it needed to be filled with some materials, and the material was Xu Mang's weakness.

What material is filled in the airgel honeycomb? Can it protect both cold and hot ends?

at this time,

It was only then that Xu Mang realized that the real difficulty was actually here!

Relying on airgel alone is not enough to obtain the desired performance. It must be a composite airgel, just like in the metamaterial research laboratory, filling the airgel with highly dispersed solid materials.

"Fuck!"

"What the hell should I do?" Xu Mang looked at the 3D model he had designed on the computer screen, and fell into a moment of confusion. What exactly does the silica airgel need to be filled with?

However, this problem,

In the end, relying on the intelligent synthesis software of the material database, it was perfectly solved. At first Xu Mang was just trying his luck, assuming that he had obtained an aerogel in a theoretical state, but after analyzing and simulating it, he really found one. kind of material.

resin,

A special resin, if it is filled into the air attack of the honeycomb airgel, it will achieve a very perfect protective effect at both ends of the cold and heat, but it also involves new problems, and the support will be lost.

no way,

Xu Mang added graphite to the aerogel, accounting for 0.4% of the total.

"solve!"

"The bottom is airtight!" Xu Mang stretched his waist. Unexpectedly, he spent an hour and a half on such a simple question. He picked up his phone and checked the time. It was already half past ten, and it was time to order a takeaway .

Ever since they lived together, Xu Mang and Xiaoman seldom eat takeaway food. Whenever conditions permit, they will cook for themselves. If they can't, they will drive to the old man's house and come back for a meal. From the perspective of affection and convenience, Xu Mang hopes to go there all the time. , because there is no need to wash dishes.

Opened the app, Xu Mang was stupefied by the dazzling store, and silently shut down the software. Sometimes Violent Airport is right. Those food delivery platform software should be smarter. According to the daily nutrition report and The previous point records can be used to deduce what to eat today.

go out,

Xu Mang went to a nearby supermarket, bought noodles, drinks, and ham sausage, and then went back to boil water. During this boring time, Xu Mang called Xiaoman.

"Hello?"

"Xiaoman...have you eaten yet?" Xu Mang asked, "Do you want me to bring it to you? Tomato scrambled eggs, shrimp fried broccoli, fried lettuce, served with delicious Wuchang rice, and served on the side Put another bowl of shrimp skin seaweed soup, what do you think?"

"Okay, okay!" Yang Xiaoman said happily: "My husband...you are too kind to me. Recently, the food in the cafeteria is unpalatable. The price of pork has risen and many of them have gone up...I am hesitating to sell the company. Let’s mention the food.”

it took,

Yang Xiaoman hurriedly asked: "Husband... when will you bring it here?"

"hey-hey..."

"I'm teasing you, I'm eating instant noodles, how can I cook for you, what are you thinking!" Xu Mang said with a smile: "The water is already boiling... let's not talk about it, let's talk about my Pagani Fengshen Why hasn't the sports car arrived in Hong Kong yet?"

"roll!!!"

Snapped!

directly hung up,

Xu Mang looked at the phone in confusion, not understanding why Xiaoman was so angry, but when Xu Mang started instant noodles, he found that he had been fooled. Yuzhongyu, all the emotions are fakes!

I can not eat it...

If there is a problem with eating, it will be a tragedy to send it to the ICU.

at noon,

Xu Mang came to Xiaoman's company, and then touched the cafeteria. He was caught by someone as soon as he arrived at the door. The key to arresting Xu Mang was none other than Yang Xiaoman, who had been blasted in anger before.

"What are you looking at!"

"Don't you eat instant noodles?" Yang Xiaoman was still worried about the food delivery, and said angrily, "Why did you suddenly run to my company's cafeteria?"

"Forget it!"

"Misfortunes never come singly. I bought three things in total, but they were all counterfeit." Xu Mang took out his mobile phone and showed Xiaoman the photos he took. What about Kang Shibo, Lei Bi and Yu Zhongyu, there was almost no violence The airport was amused.

"It deserves it!"

"This is the price for lying to me." Yang Xiaoman glared at Xu Mang, but it was her husband after all, and they both ordered meals and sat together for lunch.

This scene,

It made many single women in the company envious.

"I think..."

"Stop coming to your company in the future." Xu Mang said solemnly, "You have too many single women here. My presence will affect the stability and unity within your company, and it will also affect your rule."

"..."

"Idiot!" Yang Xiaoman said angrily, "Can you stop being so narcissistic? Didn't you go to school today?"

"Um!"

Xu Mang nodded, and said seriously: "Xiaoman...after mid-October, I may go to the capital to work for a while, you...what do you say?"

Hearing Xu Mang's words,

Yang Xiaoman suddenly stopped moving, looked at Xu Mang in surprise, and asked, "How long...how long have you been there?"

"About a month."

"In short, it won't be too long, but it won't end in a day or two." Xu Mang said helplessly, "I wanted to tell you before I left, but I think I should tell you now, because you will know anyway."

Yang Xiaoman pouted, and said with a little dissatisfaction: "Then you have to be good in the capital, don't mess around outside, if I find out... don't blame me for being rude!"

Xu Mang shrank his head: "Don't worry, I've always been honest!"

At first, he thought it was a storm of crying, but nothing happened. At that time, Xu Mang was relieved. He hated seeing a woman cry. Once she cried, his heart might soften and he would not go. .

after dinner,

After bidding farewell to Xiaoman, Xu Mang returned home and continued his aerogel journey. According to his estimation, it would take up to two hours.

...

Beijing,

Metamaterials Research Laboratory,

Professor Lu Jianping Lu just finished handling things, and then received a call from the Huaguo Space Administration.

"Professor Lu?"

"How's the material progress of the pneumatic reducer?" The other party asked curiously: "I heard...you seem to have encountered some troubles, which has caused the progress to stagnate. If this is the case, please add Power, the pneumatic reducer is very important in the whole link!"

"Secretary Tian."

"It is true that we have encountered a lot of trouble, but we have worked hard to solve this problem." Professor Lu said with a wry smile: "If it is an ordinary aerogel, there is no pressure at all. Now many private companies are developing and selling it. Aerogels, but aerogels in the aerospace field are controlled by Europe and the United States.”

"It can be said...we are completely blocked." Professor Lu said: "Many of them start from scratch."

"I know your difficulties... But this pneumatic reducer is an indispensable part of the Mars project. You are the only organization in China that can research it. You can only..." The other party paused, and then said: "Turn the pressure into Motivation, let’s say... isn’t there any progress now?”

"almost."

"However... we found other people to solve this problem." Professor Lu said.

What?

its...others?

What's happening here?

"Professor Lu?"

"You didn't tell about the space program, did you?" the other party asked in horror.

"No!"

"Just sent our research data over, don't worry...he decided not to know." Professor Lu said seriously: "And this person is trustworthy, he is Xu Mang, professor of theoretical physics at Fuda."

Xu Mang?

He even knows this field?

The other party didn't believe it a little bit, Xu Mang... too well understood, the cooperation between the space agency and NASA on the exploration of the far side of the moon was based on Xu Mang, and the space agency's Mars program would invite Xu Mang to participate together one day into this project.

after all,

Xu Mang is an authority in the field of astrophysics, and there are many problems that need him to solve.

"Professor Xu..."

"He...he even knows this?" the other party asked curiously.

"I don't know..." Professor Lu said with a bitter smile: "But I'm sure, the result will be known tomorrow. According to Professor Xu Mang at the time, if it can be solved, it only takes one day. If it can't be solved... Ten Neither can God."

"..."

"one day?"

"Professor Tian, ​​if Professor Xu really solves the problem, please be sure to experiment carefully." The other party said seriously: "If this problem is solved so quickly, many problems will definitely arise. By then... you You have to be careful and careful!"

It wasn't that Secretary Tian was narrow-minded and didn't trust Xu Mang, but... It took only one day to solve the problem that the Metamaterial Research Laboratory had been unable to solve. It is conceivable that there must be many problems in it.

"Do not worry!"

"Secretary Tian...we will be very careful when the time comes." Professor Tian said: "But...don't take Professor Xu Mang's words seriously, I guess he may be joking, if it can be solved, it will take at least a week time."
