I really don't want to lie down and win

"Even...even you can't solve this problem?" He Fang sighed, with a bit of bitterness in her words: "I'm sorry...to bother you."

Xu Mang:? ? ?

what's the situation?

What unsolvable problem?

Are you and him chatting on the same channel?

"and many more!"

"You... You called me to solve the problem, right?" Xu Mang asked curiously, "The research materials you just sent me are the problems you encountered in your research project, right? Let me do it." solve?"

"..."

"Haven't we been discussing this topic?" He Fang asked confusedly: "The Metamaterial Research Laboratory has encountered an unsolvable problem, and I plan to ask you to help us solve this problem."

Xu Mang: °ー°〃

I...

It turned out to be a misunderstanding.

"Cough cough!"

"Oh..." Xu Mang smiled awkwardly but still politely: "Then what...give me a day, I'll study it carefully, and I'll give you an answer tomorrow."

"one day?"

"Professor Xu Mang... Are you sure one day is enough?" He Fang asked in surprise, "Actually, it doesn't matter if you have a few more days. You have already been trapped for more than ten days, and it will be the same if you have a few more days."

"One day is enough."

"Whether I can solve this problem or not, after spending a day thinking about it, I will almost have the answer." Xu Mang said calmly, "If I can solve it, let alone a day... half a day, if I can't Even if I solve the problem in ten days, I won’t be able to solve it.”

"Then... good!" He Fang said seriously, "I'm sorry to trouble you!"

After hanging up the phone,

Xu Mang's eyes returned to the screen, looking at the above research data, it seems to be a kind of airgel, the lightest solid in the world, because of its high specific surface area and low thermal conductivity, it is widely used in aerospace vehicles Heat-resistant material.

Currently,

This high-end technology is in the hands of Europeans and Americans.

Speaking of...

What is the problem?

After continuous in-depth research, Xu Mang discovered the problems encountered by the metamaterial research laboratory. Their aerogel is mainly used to develop heavy-duty transportation technology, and the supersonic inflatable aerodynamic reducer provides effective braking for spacecraft. Load and volume benefits.

So far,

Structural design needs to be innovative, and the combination of outer layer, thermal insulation layer and airtight layer can make it play its biggest role.

If you guessed right,

According to this technical indicator, it seems to be the Mars landing plan. When the aircraft is about to land on Mars, it will automatically open the pneumatic reducer with a diameter of ten meters to decelerate reasonably, so that the Mars rover inside can land smoothly.

Ugh?

Now that the specific landing issue has been raised, is it possible that... the Mars rover has been developed?

Wouldn't I be busy working in vain?

When Xu Mang thought of all the information on the Curiosity Mars rover in his hand, he felt extremely heartbroken. He knew that he would have changed to another technology, and now it's better...It's all in his hands.

Trying to calm down his emotions, Xu Mang looked at the problem in front of him. This is an opportunity to show his strength. How to get the metamaterial research laboratory to cooperate with him depends on whether he can solve the problem in front of him.

At this time,

He thought of a solution,

is it hard?

Not difficult!

The Xu Yang structure is on the scene again!

......

6Chapter 16 Must Be Serious (2/3)

For the structural change, Xu Mang didn't even need to conduct any experiments. There are still 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 [-]% of that of the earth, and the surface atmospheric pressure is only [-] to [-] 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 [-]G 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!

Simply relying on airgel 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.
