The third problem is gravity.

This one is a bit technical.

Outer space is also gravity-free. People can get out of control. will float.

The corresponding gravity must be simulated in order to adapt to the living habits of ordinary people. You can't ask ordinary people to be like astronauts.

Astronauts are trained in the most professional way. Do immigrants also need to be trained?

Who else wants to emigrate if it's so troublesome?

How do you model gravity?

It is also necessary to learn from the 591 project.

Basically, Shi Zhongjian is responsible for manufacturing. The real specialty is Project 591.

Therefore, Wang Buan's next stop is the 591 Project.

591 Space Center, to be exact.

"The materials are ready. ”

"It's all here. ”

"The two of us went together. ”

"I'm going too?"

"Of course. ”

"Good. ”

Shi Zhongjian quickly packed up the information.

Not to mention, he and Loma Chuan of the 591 Space Center are classmates in middle school and college.

It's just that later they went their separate ways, and everyone worked in a secret unit, but they never had contact. Until Wang Buan involved the two of them together. It's a chance to get together.

Soon, the two came to the space center.

This place, codenamed Project 591, is very large.

It undertakes a lot of research tasks. Satellite launches, outer space exploration, and intercontinental missile research are all their work.

They were responsible for a series of previous spacewalks, satellite positioning, and moon landing programs.

From this point of view, Wang Buan is suspected of smashing people's jobs.

Of course, the staff of the space center have high ideological consciousness and will not worry about Wang Buan.

But privately......

Wang Buan came to the 591 Space Center.

At first glance, he saw Loma Chuan.

"Wang Buan, you are not a friend enough. "When we met, Lomachuan was very unhappy.

"I'm sorry. Wang Buan had no choice but to apologize honestly.

Before, he did not say goodbye.

However, Lomachuan would not forgive him.

This Professor Luo is also a bit brainless.

In his opinion, Wang Bu'an brushed his sleeves and left without even saying hello, which was obviously too rude.

He doesn't like to deal with people who are not polite.

He doesn't even have basic politeness, and he is definitely not a literate person.

"What are you doing with me?" Fortunately, Professor Luo's temper came and went quickly.

He also knew that Wang Bu'an had nothing to do but go to the Three Treasures Palace. There must be something important.

The most important thing is that the old classmate Shi Zhongjian also came.

No one can give face. But the face of the old classmates must be given.

Their generation still cherishes the friendship of classmates and comrades-in-arms very much. It's definitely not as rash as young people nowadays.

If you don't agree with each other, you will be ruthless, and you don't know how to cherish yourself.

"I want to work with you on the production of the space shuttle. Wang Buan said straight to the point.

"You Tyrannosaurus Rex Industries want to produce space shuttles?" Lomagawa was taken aback.

"Yes. Wang Buan nodded without hesitation.

"So, you're coming to us?" Lomachuan felt incredulous.

You say, is this a door-to-door challenge?

You came to the space center and said, I'm going to develop a space shuttle?

It's like running to the hospital and shouting, "I'm better than yours, I'm going to do it myself!"

Do you think someone will beat it up and throw it out?

By the way, do you Tyrannosaurus Rex Industries have experience in space exploration?

Do you know what a space shuttle is?

Do you know what outer space looks like?

Don't think that if you can make a normal airplane, you can make a space shuttle!

The two are completely different, okay?

One flies inside the atmosphere.

One is flying outside the atmosphere.

Ordinary airplanes face an environment with air, oxygen, normal pressure, and gravity.

However, the space shuttle faced a special environment with no air, no oxygen, no pressure, and no gravity. There is no way for ordinary people to survive. To go up is to die.

"Are you serious?" asked Lomagawa slowly.

"I'm serious. Wang Buan replied solemnly.

"Are you serious, too?" said Lomagawa, turning his head to look at his old classmate.

"I'm serious too. Shi Zhongjian replied solemnly.

"Okay, I'm going to ask my superiors. ”

"Please. ”

"You sit down first. ”

"Good. ”

Lomachuan left in a hurry.

This kind of thing, he needs to report it quickly. After all, it's about Wang Buan.

Seriously, if someone else had made such a suggestion, they would have been beaten out of the door by Luo Machuan a long time ago. What a madman, run to the space center to spread wild. Don't look at what kind of place it is.

However, this matter was raised by Wang Buan. Wang Buan also repeatedly confirmed that it was serious and serious, and the situation was serious.

With Wang Buan's personality, since he said that he wanted to do it, he must be somewhat sure.

Who is Wang Buan?

The head of White Feather Whale Technology.

The head of the Tyrannosaurus Rex industry.

Both of these titles are very eye-catching.

Especially in the field of industry and technology, these two names can be described as golden signs, and they are very loud.

"Wang Buan, the lunar landing program, the space shuttle?"

That's what he said. ”

"This little guy really dares to think about it!"

"Then we ......"

"I'll go talk to him. ”

"Okay. ”

Soon, Lomachuan returned.

He had another man with him. A tall, thin old professor.

He is the head of the space center. It's called Liang Wannian.

"We seem to have met?" Wang Buan nodded thoughtfully.

"I participated in the 3,000-person conference. Liang Wannian replied quietly, "I have some understanding of nuclear fusion." ”

"That's going to be easy. Wang Bu'an said happily, "I don't hide it." Let me tell you, I have developed a nuclear fission reactor that can be used on the space shuttle. ”

"Really?"

"Of course!"

Liang Wannian suddenly became eager.

It was meant to be refused. Immediately changed my mind.

What is the most important component of the Space Shuttle?

It's the power system!

At the same time, it is the most dangerous part of the shuttle.

The power system involves fuel, avionics, various cables, and high temperatures, and is the most prone to accidents.

Every time a rocket is launched, the power system must be checked repeatedly and must be 100% safe.

However, even then, there are occasional rockets that crash due to malfunction.

The success rate of Huaxia's rocket launch is also not 100%.

Compared with foreign countries, our success rate is a little higher. But there are accidents that happen.

What is the most important point of the moon landing program?

In fact, it is also motivation!

The power to be able to reach the moon.

The power that can send both people and equipment to the surface of the moon.

There are a lot of industries involved, and all kinds of expertise can fill hundreds of terabytes of hard drives. Or the one without video.

For interstellar travel, nuclear power is undoubtedly the best power. High power and long battery life.

Basically, you don't need to change the fuel for a few years or more than a decade.

If it's for the space shuttle, that's great.

The space shuttle can shuttle back and forth, and there is no need to refuel repeatedly!

Both liquid oxygen and liquid hydrogen are very dangerous. In the process of mixing, it can also be highly toxic. If you are not careful, you will have a safety accident.

Of course, nuclear power units are also very dangerous. In the event of an accident, the consequences are even more dire.

"Where is the nuclear power you are talking about?" asked Liang Wannian cautiously.

"I've already brought it. Wang Bu'an pointed outside.

"I'll see. ”

"Please. ”

The group came to the airport outside.

The inconspicuous nuclear fission reactor hangs in the belly of the Little Golden Dragon helicopter.

"Where is it?" asked Liang Wannian blankly.

"Here it is. Wang Buan pointed under the helicopter.

"Is this the thing?"

"That's right. ”

"Such a small one?"

"Don't look at it small. The quality is still great. Twenty tons. ”

"You ......"

Liang Wannian wanted to speak and stopped.

He really wanted to say, you Wang Bu'an won't fool me.

Nuclear fission reactors!

Such a small guy? Twenty tons?

He had never seen such a tiny nuclear fission reactor...... Current technology simply can't do that.

The existing nuclear reactors are quite large. At least the size of several containers. And you ended up bringing a suitcase? Or a 24-inch suitcase?

"How did you miniaturize nuclear fission?" said Liang Wannian, incredulously.

"Trade secrets, no comment. Wang Buan said calmly.

"But ......"

"If you don't believe it, don't you know if you try it?"

"Okay. ”

Liang Wannian nodded.

Indeed, there is no basis for words. It's better to go straight to the real thing.

It doesn't really matter whether this thing is a nuclear fission reactor or not. The important thing is to be able to provide strong motivation.

The power that the space shuttle needs is very strong. The thrust is at least 100 tons.

There must be enough thrust to push the shuttle above 25 times the speed of sound. Otherwise, there is no way to break out of the atmosphere.

Previous satellite launches have used ultra-high-thrust bundled rockets. For example, the Long March-2, the Long March-4 or something.

In the past, the one with the largest thrust was the Long March-2F improved version, with a maximum thrust of nearly 600 tons!

It uses nitrous tetroxide as an oxidizing agent and metamethylhydrazine as an incendiary agent.

Now, the Long March 5, which has the largest thrust, has a maximum thrust of more than 1,000 tons!

It uses liquid oxygen, liquid hydrogen, kerosene, etc., as propellants.

There is also the Long March 9 rocket under demonstration, which will have a maximum thrust of 6,000 tons.

It can send more than 4,000 tons of supplies into outer space.

"Rated thrust 200 tons. Wang Buan said.

"It can carry about 100 tons. Lomachuan nodded.

The maximum take-off weight of the space shuttle can reach about 120 tons. Wang Buan said lightly.

"In the long run, it's more practical than the fat five. Shi Zhongjian said.

Fat Five is the Long March 5.

This cute nickname has two origins:

First, it has a diameter of more than five meters.

Second, it is numbered Long March 5.

For a long time, the Fat Five has been the largest launch vehicle in Huaxia.

If it is simply into outer space, it can even transport 800 tons of supplies.

However, the rest of the voyage was a bit of a problem.
