I really don't want to lie down and win

"No!"

"I accidentally finished it a day early." Xu Mang showed a slight smile, took out a stack of white papers from his satchel, handed them to Director Guo, and said with a smile, "Director Guo, take a look." , This is the result of my research that I have failed your two-day expectations and completed one day ahead of schedule."

what?

he...

He finished ahead of time?

Director Guo took it in his hand with a look of horror, and hurriedly flipped through the contents, not to mention...he flipped through it by himself, it was not Xu Mang's graffiti, the handwriting was clear and concise, and it contained a lot of calculation process.

Is it...

He really worked it out?

As an expert in this field, Director Guo calmed down and planned to review carefully from the first page, not letting go of every detail. There is still an hour before the end of get off work, and this hour should be almost the same.

"Xiao Xu?"

"How about...you go back first?" Director Guo said, "I'll give you an answer tomorrow."

"Ha ha."

"No rush." ​​Xu Mang shook his head, and said calmly, "Look...if there is any problem, we can solve it face to face."

"Alright!"

"Then thank you for your hard work." Director Guo nodded, and immediately began to review the research report, but after only 5 minutes, Director Guo's eyes changed, and his expression also twisted together.

suddenly,

Director Guo raised his head and stared at Xu Mang in horror. He tried hard to speak, but he still didn't know what to say. In short, there were no words to describe his inner emotions at this moment.

have to say,

Just what I saw in the 5 minutes just now has completely subverted my understanding of the whole world.

he...

How on earth did he do it?

I didn't see him working hard, but one day he came to visit with a complete research report...and said it was completed.

This...

what on earth is it?

suddenly,

Director Guo thought of his old friend, Xu Mang's uncle, what he said to him, Xiao Xu has such a work attitude, you don't need to talk to him, just let him fend for himself...

Now that he revisited this sentence again, he realized that what he said perfectly matched Xu Mang's own behavior. Could it be that... he has this kind of lazy work attitude?Doesn't it make sense for him to be late and leave early all day?

"Xu..."

"Xu Mang?!"

"You did this by yourself?" Director Guo asked seriously. He also changed his address to Xu Mang and called him by his name directly.

"Yup!"

"I just spent the whole morning today, alas... I didn't even eat lunch, I was starving to death..." Xu Mang said with a miserable face, "I spent almost three For half an hour, the hand almost didn't break."

"..."

Director Guo didn't say a word. He didn't believe that this research report was completed today, and it only took three and a half hours. However, he didn't want to delve into it too much. Once it's finished, it's done. It's up to you how to finish it. The more you ask, the more confused you become.

When Director Guo continued to delve into this research report, gradually...he found that he could no longer keep up with the content. As an expert in this field, he was already confused about some of the content.

Carbon fiber reinforced silicon carbide composites?

According to Xu Mang's research results, carbon fiber reinforced silicon carbide composite materials have the advantages of low density, high strength specific modulus, large damage limit, extremely high temperature resistance, good oxidation resistance, and strong corrosion resistance.

keep reading,

Director Guo saw the research on active cooling structures, and only then did he realize that this research report is really not simple!

Carbon fiber reinforced silicon carbide composites can only be used for one-time use, and this time is very short, only half an hour. If you want to have a longer time, or even reuse it, you must combine it with an active cooling structure.

And this aspect has been proposed by the laboratory, but it is too difficult. In addition, the laboratory has not even got the materials, so it directly gave up the idea of ​​combining materials and cooling structures.

but...

Unexpectedly, Xu Mang brought it up again today.

Wait a moment...

Not right!

The information given to him didn't contain any active cooling structures, he... how did he know?

"Xiao Xu?"

"You...you tell me the truth...how did you know about the active cooling structure?" Director Guo asked, "Did someone tell you?"

"No!"

"I thought of it myself." Xu Mang said with a smile: "Based on my calculations, the use limit of carbon fiber reinforced silicon carbide composite materials is half an hour. Once it exceeds half an hour, various situations will occur. , After all, materials also have a certain lifespan.”

"According to this situation, I'm thinking... how to increase the service life in other ways without improving the performance of the material?" Xu Mang said: "I thought of the cooling method of carbon fiber reinforced silicon carbide composite material combined with metal. "

genius!

What a genius!

Director Guo looked at Xu Mang seriously. He didn't know the young man in front of him at all. You said he was lazy?That's really lazy... It's commonplace to be late and leave early, you say he is hardworking, right?That was real hard work again, and all of a sudden the project was done by him.

When his eyes returned to the research report, Director Guo discovered that Xu Mang actually provided two structural methods. The first one is the combination of materials and metals, while the second one is the all-composite cooling structure. Both have their own advantages. .

See here,

Director Guo closed the bound research report, and said seriously with a glance: "Xiao Xu... I will give you an answer tomorrow. I am not the only one who has the final say on such a big matter. We are only responsible for researching scram For the engine, the details need to be discussed with other departments.”

"Oh..."

Xu Mang thought for a while, then said cautiously: "Then can I leave the laboratory first? Call me if there is any problem... I didn't run away on purpose, because the space agency still needs me, you should know that I want to What to do."

words fell,
