Chapter 631: Door-to-door challenge?

The third problem is gravity.
This is a bit technical.
There is no gravity in outer space. People will lose control. Will float.
The corresponding gravity must be simulated to adapt to the living habits of ordinary people. You can't ask ordinary people to be like astronauts.
Astronauts have received the most professional training. Should immigrants also receive training?
If it's so troublesome, who else wants to immigrate?
How to simulate gravity?
Also need to learn from the 591 project.
Basically, Shi Zhongjian is responsible for manufacturing. The real profession is Project 591.
Therefore, Wang Bu'an's next stop is Project 591.
To be precise, it is 591 Space Center.
"The information is ready."
"It's all here."
"The two of us will go together."
"I also need to go?"
"of course."
"it is good."
Shi Zhongjian quickly collected the information.
Not to mention, he and Lomachuan of 591 Space Center are classmates in middle school and university.
It's just that afterwards they went their separate ways. Everyone worked in a confidential unit, but never contacted. Until Wang Bu'an got the two of them together. It's just a chance to get together.
Soon, the two came to the space center.
This place, code-named Project 591, is very large.
It undertakes a lot of research tasks. Satellite launches, outer space exploration, and intercontinental missile research are all their activities.
They were responsible for the previous series of space walks, satellite positioning, and moon landing plans.
From this perspective, Wang Bu'an is also suspected of smashing people's jobs.
Of course, the staff of the Space Center have high ideological consciousness and will not care about Wang Bu'an.
But in private...
Wang Bu'an came to 591 Space Center.
At first glance, he saw Lomachuan.
"Wang Bu'an, you are not friends enough." Luo Machuan was very upset just after they met.
"I'm sorry." Wang Bu'an had to apologize honestly.
Before, he did leave without saying goodbye.
However, Lomachuan will not forgive him.
This Professor Luo is also a bit stupid.
In his opinion, it is obviously too rude for Wang Bu'an to leave without saying hello.
He doesn't like dealing with impolite people.
He doesn't even have basic courtesy, and he is definitely not a well-trained person.
"What are you doing with me?" Fortunately, Professor Luo's temper came quickly and disappeared quickly.
He also knew that Wang Bu'an was in the Three Treasure Hall without incident. There must be something important.
The most important thing is that old classmate Shi Zhongjian also came.
Nobody can give up any face. But the face of old classmates must be given.
Their generation still cherishes their classmates and comradeship. It's definitely not as rash as young people nowadays.
If you don't agree with me, I will hang myself ruthlessly. I don't know how to cherish myself.
"I want to cooperate with you to produce the space shuttle." Wang Buyan said straightforwardly.
"Your Tyrannosaurus rex industry wants to produce a space shuttle?" Lomachuan was taken aback.
"Yes." Wang Bu'an nodded without hesitation.
"So, you come to us?" Lomachuan felt incredible.
Do you think this is a door-to-door challenge?
You came to the space center and said, I want to develop a space shuttle?
This is like going to the hospital and shouting, my medical skills are better than you, I want to do it myself!
Do you think you will be violently beaten and thrown out?
In other words, does your Tyrannosaurus rex industry have experience in space exploration?
Do you know what a space shuttle is?
Do you know what outer space is like?
Don't think that if you can produce ordinary airplanes, you can make space shuttles!
The two are completely different, okay?
One is flying in the atmosphere.
One is flying outside the atmosphere.
An ordinary aircraft faces an environment with air, oxygen, normal pressure, and gravity.
However, the space shuttle faces a special environment with no air, no oxygen, no pressure, and no gravity. There is no way for ordinary people to survive. Going up is dead.
"Are you serious?" Lomachuan asked slowly.
"I'm serious." Wang Bu'an replied solemnly.
"Are you serious too?" Lomachuan turned to look at his old classmate.
"I'm serious too." Shi Zhong replied firmly.
"Well, I want to ask my superiors."
"please."
"Sit down first."
"it is good."
Lomachuan hurriedly left.
He needs to report such things quickly. After all, it's about Wang Bu'an.
Seriously, if someone else made such a suggestion, he would have been beaten out by Lomachuan. What lunatic, ran to the space center to run wild. Don't see where it is.
However, this matter was raised by Wang Bu'an. Wang Bu'an also repeatedly confirmed that he was serious and serious, and the situation was serious.
With Wang Bu'an's personality, since he said to do it, he must be somewhat certain.
Who is Wang Bu'an?
The head of White Whale Technology.
The head of Tyrannosaurus industry.
These two titles are very eye-catching.
Especially in the fields of industry and technology, these two names can be described as golden signboards, very resounding.
"Wang Bu'an? Moon landing plan? Space shuttle?"
"That's what he said."
"This little guy really dare to think about it!"
"Then we..."
"I'll talk to him."
"Ok."
Soon, Lomachuan returned.
There was another person by his side. A tall and thin old professor.
He is the head of the space center. It's called Liang Wannian.
"We seem to have met?" Wang Bu'an nodded thoughtfully.
"I have participated in the 3,000-person meeting." Liang Wannian replied calmly, "I have some understanding of nuclear fusion."
"Then it will be easy." Wang Bu'anxin said happily, "I don't hide it. I 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 rejected. Changed his mind immediately.
What is the most important part of the space shuttle?
It's the power system!
At the same time, it is also the most dangerous part of the space shuttle.
The power system involves fuel, avionics, various cables, and high temperatures, which are the most prone to accidents.
Every time a rocket is launched, the power system has to be repeatedly checked and must be 100% safe.
However, even so, occasionally there will be rocket failures and crashes.
China’s rocket launch success rate is not 100%.
Compared with foreign countries, our success rate is a bit higher. But there are also accidents.
What is the most important point of the moon landing plan?
Actually it's also motivation!
The power to reach the moon.
The power that can send people and equipment to the lunar surface.
There are many industries involved, and all kinds of professional knowledge can fill hundreds of terabytes of hard drives. Still the one without video.
For interstellar navigation, nuclear power is undoubtedly the best power. High power and long battery life.
Basically, there is no need to change fuel for several years or more than ten years.
If it is used on the space shuttle, that would be great.
The space shuttle can shuttle back and forth without refueling at all!
Liquid oxygen and liquid hydrogen are both very dangerous. In the process of mixing, it will also produce highly toxic. A little carelessness can cause a safety accident.
Of course, nuclear power plants are also very dangerous. Once an accident occurs, the consequences are even more disastrous.
"Where is the nuclear power you are talking about?" Liang Wannian asked cautiously.
"I already brought it." Wang Bu'an pointed outside.
"Let me see."
"please."
A group of people came to the airport outside.
The unremarkable nuclear fission reactor was hung in the belly of the Xiao Jinlong helicopter.
"Where is it?" Liang Wannian asked blankly.
"Here." Wang Bu'an pointed under the helicopter.
"Is this thing?"
"Yes."
"Such a small one?"
"Don't look at it small. The quality is still great. Full of twenty tons."
"you……"
Liang Wannian hesitated to speak but stopped.
He wanted to say, Wang Bu'an is not fooling me.
Nuclear fission reactor!
Such a small guy? Twenty tons?
He has never seen such a miniature nuclear fission reactor... The current technology simply cannot do it.
The existing nuclear reactors are quite huge. At least the size of several containers. In the end, you got a suitcase? Or a 24-inch suitcase?
"How did you miniaturize nuclear fission?" Liang Wannian said dubiously.
"Commercial secrets, no comment." Wang Buan said frankly.
"but……"
"If you don't believe it, don't you know if you experiment?"
"Ok."
Liang Wannian nodded.
Indeed, there is no proof. It's better to come directly.
Whether this thing is a nuclear fission reactor or not is actually not important at all. The important thing is to be able to provide strong motivation.
The power required by the space shuttle is very powerful. The thrust is at least 100 tons.
There must be enough thrust to push the space shuttle above 25 times the speed of sound. Otherwise, there will be no way to break out of the atmosphere.
The previous satellite launches were all bundled rockets with super-high thrust. For example, Long March-2, Long March-4 or something.
In the past, the largest thrust was the Long March 2 f-modified model, with a maximum thrust close to 600 tons!
It uses dinitrogen tetroxide as an oxidant and unsymmetrical dimethylhydrazine as a combustion agent.
Now, the Long March No. 5 with 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 demonstration of the Long March 9 rocket, which will have a maximum thrust of 6,000 tons.
It can send more than 4,000 tons of materials into outer space.
"The rated thrust is 200 tons." Wang Bu'an said.
"It means it can carry about 100 tons~EbookFREE.me~Lomachuan nodded.
"Yes! The maximum take-off weight of the space shuttle can reach about 120 tons." Wang Bu'an said lightly.
"In the long run, it is more practical than Fat Five." Shi Zhongjian said.
Fat five is Long March number five.
This cute nickname has two origins:
First, its diameter exceeds five meters.
Second, its number is Long March No. 5.
The Fat Five has always been China's largest carrier rocket.
If it is simply entering outer space, it can even transport 800 tons of materials.
However, the next voyage is a bit troublesome.
