The little assistant was stunned for a while.

He didn't know what the other side was talking about, but he saw Dean Duanmu completely stunned in place, not speaking or speaking, as if he had been drained of his soul.

Dean Duanmu took the mobile phone next to his ear and looked at it, at this moment his face was full of doubts, and even his eyes were confused.

When he looked up and looked at the little assistant not far away, the two of them looked at me, and I looked at you, both of them looked confused.

Until Lin Yuanyong, 'Are you listening?' The various shouts of "Can you hear it" pulled Dean Duanmu, who was confused and began to doubt his life, back.

"Ahh

"Listening."

"Listening."

Dean Duanmu put the phone to his ear again, "It's just that the signal was a little bad just now." ”

"Didn't you hear what you just said?"

"Say it again."

Lin Yuan said with his heart that it was the Xiangfeng Rocket Launch Base!

Where the rocket can receive signals in outer space, there is no reason why the mobile phone signal will be bad?

In line with the idea of saving time, Lin Yuanyong had no choice but to speak sharply:

"I just said."

"Because of some special needs."

"We're going to use that heavy rocket you have on hand to try to transform it?"

"Let's see if we can recycle and reuse multiple times."

Dean Duanmu: "."

That's right!

He had heard it right!

Sure enough, it's like this!

Heavy rockets are recycled and reused many times?

Would you like to hear what you're saying?!

Is this something that is possible?

"Lao Lin?"

"Do you know what you're talking about?"

"Heavy rockets are recycled and reused many times?"

Dean Duanmu said excitedly: "There is no country in the whole world that can do it!" ”

"This technology is simply not possible at the moment!"

"If it weren't for you Lao Lin who made this call, I would have hung up a long time ago!"

It's normal not to believe it.

Lin Yuan thought that someone would call him and say that he could make an airborne device in outer space orbit, and he must not believe it.

What about playing?

"Don't get excited."

"Don't get excited."

Lin Yuanyong said slowly: "What if I tell you that this matter has Elder Zhang's authorization? ”

"Ask other units to agree unconditionally and cooperate with all actions?"

Dean Duanmu was shocked!

If Elder Zhang really gave such an order, then things would be completely different.

"Zhang Lao."

"Did Elder Zhang really give such an order?" Dean Duanmu Wu Zi couldn't believe it.

"Old man, how can I joke with you about this kind of thing?" Lin Yuanyong said, "We'll leave now, and it's estimated that we will be there for you in two days." ”

"When the time comes, I'll show you the paper documents, the kind stamped with a big red stamp, and you can't keep them fake!"

That's a lot of certainty.

It's very swearing.

Dean Duanmu knew that Elder Zhang's order must not be fake.

Can.

Heavy rocket recycling?

As the head of the first academy, as a technician who has been in the field of rockets for decades, he deeply understands how difficult the technical problems are.

First of all, the problem of materials, in order to achieve reuse, can the material withstand thousands of degrees of high temperature and high pressure repeatedly without deformation?

The second is the engine, which can be reused?

At present, the delicate rocket engine can only be used once, and although it can be used more, there are great safety risks.

In general, it will not be used again.

Of course, compared to hardware, the most difficult thing is software.

Rocket recovery is mainly to recover the first stage of rockets, which is expensive, and successful recycling will greatly reduce the cost.

But there is one of the most difficult places.

When the first-stage rocket completes its mission and detaches from the fall, the situation is extremely complicated.

Wind power, speed, attitude, and so on all have to be taken into account, and the variables are extremely complex.

The effective window period is less than two or three hundred milliseconds.

If you miss it, you may never be able to guarantee that it will be successfully recovered.

In other words, there must be such a landing segment guidance algorithm that can calculate the magnitude and direction of engine thrust in real time in two or three hundred milliseconds to achieve safe and accurate landing.

It's hard!

It's almost impossible!

All of the above are problems that cannot be solved at present, and it also makes Dean Duanmu more and more determined in his heart.

"Good!"

"Good!"

"Then I'll be waiting for you to come in two days!"

"I'd like to see it?"

"What kind of transformation is it? What kind of technology? ”

"It can make heavy rockets recyclable!"

The little assistant watched Dean Duanmu hang up the phone emotionally.

He still didn't know what was being said on the other side to make his originally calm dean so excited.

On the right hand side of the sight, another old man walked with his hands behind his back, dressed in a white research suit, if he didn't have a bald head, he still looked quite handsome.

"Hello Vice Dean Zeng~" The little assistant greeted politely.

Vice President Zeng also nodded politely in response.

He walked up to Dean Duanmu with a smile and asked with a smile, "What's wrong?" ”

"Why do you look like you've lost your soul?"

"Did you not sleep well last night?"

"Or is it that after working overtime all night, the spirit is gone?"

In the face of this old friend's jokes, Dean Duanmu rarely had no intention of playing.

He just looked at the heavy rocket in front of him, and slowly spoke: "Old Zeng? ”

"If Anyone Told You"

"Heavy rockets can be recycled and reused many times, what do you think?"

Vice President Zeng was stunned for a moment, and then burst out laughing.

"What do you think?"

"Lying in bed and thinking, there is everything in my dreams."

Are you kidding?

Heavy rocket recycling?

What's the difference between this and having a three-year-old solve the Riemann conjecture (the top 10 math puzzles)?

It's just a joke!

Something simply can't be done!

Facing Lao Zeng's hippie smile, Dean Duanmu said in an unusually serious tone:

"That's what I actually thought."

"But."

"Lao Lin called me just now, saying that someone can do it, and he will come over in two days to do the experiment."

"Elder Zhang also personally gave an order to cooperate unconditionally."

The smile on Vice President Zeng's face suddenly disappeared.

He was stunned for a moment, "What"

"What?"

"What did you just say?"

meanwhile

069 base, in the dean's office,

"We've been contacted over there." Lin Yuanyong waved his mobile phone, "There will be no problem." ”

Su Chen nodded.

Chief Engineer Qi on the side couldn't hold back his curiosity and asked, "Chief Master Su?" ”

"What are you going to do?"

Su Chen spread out the drawings of the rocket on the table.

"If you want to realize the recycling and reuse of heavy rockets many times, the first thing to solve is the material problem."

"It's not a difficult problem to solve."

"We can use the same material as the orbital airborne generator from outer space."

"The only problem is to build these very special super alloys as soon as possible according to the dimensions on the rocket drawings."

"Next, we're probably going to be busy!"

As Su Chen said.

Next, the entire 069 base will enter the full-fire mode.

Started 24-hour full-load non-stop manufacturing of super alloys.

Usually during the day, Su Chen would personally go to the scene to stare at it.

And at night, Chief Engineer Qi, Shi Weiwei and others watched at the scene.

Time is tight, and the task is heavy.

Everyone is on standby.

In this way, two days passed in a hurry.

Just two days didn't make all the superalloys needed for the rocket.

But the progress made Su Chen satisfied, as long as the production continued at this speed, the progress of the later transformation rocket would not be affected.

Two days later.

An army-green jeep slowly drove into the Xiangfeng rocket launch base.

It was almost early in the morning, and Dean Duanmu and Vice Dean Zeng were waiting at the door.

"Bang ——!"

The army-green car door opened, and Lin Yuanyong stepped down from it.

Chief Engineer Qi, Su Chen and Shi Weiwei got off from the other side.

"Dean Duanmu~"

"Long time no see."

Lin Yuanyong took the initiative to step forward to say hello.

"Haha!"

"Long time no see, long time no see." Dean Duanmu said with a smile.

The two of them shook hands together.

Talking and laughing, Dean Duanmu looked straight at the chief engineer.

Gray-haired, with hands behind his back, he is very leader-like, but his skin is a little whiter, but he is such a person, it should be this guy!

"I guess this is the expert who proposed the reuse of heavy rockets?" Dean Duanmu asked with a smile.

Vice President Zeng also thinks so.

As for the two young men in the back?

Nonsense!

It must be an assistant!

It's normal for the dean to have an assistant next to him or something.

Isn't it just right for two people to have one for each person?

Lin Yuanyong and Chief Engineer Qi glanced at each other and immediately laughed.

"Not me."

"Not me."

Chief Engineer Qi smiled and hurriedly waved his hand, "It's not me." ”

"I don't have that ability."

As soon as these words came out, Dean Duanmu and Vice Dean Zeng couldn't fix it.

Not you?

Who else could that be?

"This," Dean Duanmu glanced at the scene, and the four of them groaned and said, "Could it be that something happened?" ”

"The old professor can't come for a while?"

Hearing this, the smiles on the faces of Lin Yuanyong and Chief Engineer Qi became brighter and brighter.

Dean Duanmu watched the two of them laugh more and more happily, and ten thousand grass and mud horses rushed by in his heart.

No?

What about you?

Why are you two laughing all the time?

!

What's up?

It's that funny?

Dean Duanmu glanced at Vice Dean Zeng.

Vice President Zeng also spread his hands, indicating that I was also confused.

Seeing that Dean Duanmu was about to be anxious, Lin Yuan said with a smile, "It's here!" ”

"It's coming!"

"Of course the old professor is here!"

"It's all good things on the phone, how can you not come?"

Lin Yuanyong came to Su Chen's side and made a gesture of invitation with both hands, "Isn't he standing in front of you?" ”

？？？？？

Yes?!
