Chapter 263 Three-step plan

In the Science and Technology Museum, I can't feel the passage of any time. I don't know how long it has passed, but Xu Lei finally made a movement, controlling his eyes to withdraw from the information screen.

"Whoo~"

"It's really unimaginable!"

Under the impact of massive technical knowledge, I couldn't help feeling this sentence.

At first, he was still worried that the space elevator project was too complicated, and it might be difficult to complete it under the existing conditions, but after transferring all the technical knowledge involved into his mind and mastering it, Xu Lei realized that he was thinking too much.

The space elevator exhibits collected in the museum have a very detailed construction process and experience.

With the current financial resources and basic technical level of future technology, as long as we cooperate with the space agency, we can create a space elevator.

Besides, I believe that the above will definitely support it.

According to the introduction in the notes, the main body of the entire space elevator can be roughly divided into five parts, namely the ground station, cables, car, synchronous track and counterweight.

For the principle of a space elevator, it can be seen as a child holding a rope, putting a heavy object on one end, swinging a circle around his hand axis, and at one end of the rope close to his palm, an ant follows the tree The swing climbs up one end of the weight, and when the ant reaches that end, it reaches a certain height and has a rotational speed after the end.

The rocket's propulsion includes two directions, one is vertical ascent, and the other is lateral acceleration parallel to the Earth's surface.

The space elevator is like an ant on a rope, and the axis of the hand is like a rotating earth star. As long as it climbs in orbit, it reaches the top with the help of the earth star's rotation, and the rotation speed of the parallel surface is less than the horizontal driving force of the rocket.

But that being said, building a space elevator successfully is not an easy task, and each of the five main components is critical.

First of all, the ground station is used as the anchor point of the cable, and its location must be selected on the equator, and a tower-like building of sufficient height must be built to ensure the stability of the elevator.

As for the synchronous orbit, the current Tiangong space station is sufficient to replace it.

Only the counterweight needs to be met by building a near-Earth spaceport. Although it is only necessary to launch the cornerstone module of the spaceport in the early stage, it does not need to be able to operate. It will still be difficult to implement it.

Besides.

Most important are the cables that connect these devices.

The length of the cable must be guaranteed to be [-] kilometers, connecting the Earth Star and the Tiangong space station and the near-Earth space port. Whether it can withstand this force is the key.

After all, if the cable breaks or snaps during use, the loss and impact caused are incalculable, and the consequences are really unbearable.

In addition to the various climatic and environmental impacts that the cable will encounter, how to maintain its life is extremely important.

Because the appearance of the space elevator is originally to transport limited resources to space, if the cables need to be replaced frequently, then the original meaning will be lost, and all costs will increase exponentially.

So the choice of the cable is the most critical step.

According to the technical content, the space elevator cable uses a special carbon nanotube material, which is a tubular nano-scale graphite crystal, which has extremely high strength.

The theoretical calculation is hundreds of times that of steel.

It is also so soft that it can be considered a super fiber.

In addition, its electromagnetic properties, adsorption capacity, and other aspects of performance are extremely excellent, and it is most suitable for use as a space elevator cable.

However, with the current technological means alone, high-purity carbon nanotubes cannot be synthesized.

But Xu Lei believes that with the knowledge he has in his mind and the resources of the research center to lead Gu Sanlin's team in experimental research, he will definitely be able to find the most suitable carbon nanotubes for cables.

A large number of thoughts flashed quickly in his mind, and Xu Lei's thinking gradually became clearer.

After preliminary research, Xu Lei plans to divide the entire space elevator project into three steps and plans to complete it within one year.

The first step is to determine the location of the ground station, and immediately start the construction of the tower, which can be completed by professional and experienced Huajian.

At the same time, the space agency manufactures the cornerstone module of the spaceport and begins to launch.

Complete the construction of the counterweight.

Of course, the development of the lunar module and lunar rover must also be completed.

The second step is to use future technology to make cables with a length of [-] kilometers and the car for the space elevator to transport goods. This step is very critical.

The last remaining step is to connect the cables to other bodies to test whether the space elevator can operate successfully.

If there is no problem with these, then various resources can be transported to the space station or space port through the space elevator, and the astronauts will take the manned spacecraft, the lunar module cargo spacecraft, and set off directly from the space station to the moon.

In the future, a space station around the moon can even be built, and the Mars base of the space port will be equipped with a space army in the near future, allowing human civilization to move directly towards a second-level civilization.

After thinking so much in a short period of time, Xu Lei became even more excited, with an urge to build the space elevator.

As for the influence, he had already put it aside.

Also, although Xu Lei learned from Xingtong that North Magnesium will launch a spacecraft to restart the moon landing plan in half a year at most, building a moon base is not an easy task.

Relying on launch vehicles alone to transport various materials to the moon is not only extremely expensive, but also very efficient.

I am afraid that it will not be completed in a few years.

But the space elevator is completely different. As long as it is successfully built, a large living base can be built in a resource-rich area of ​​the moon in a short period of time, enough to accommodate many astronauts.

And it can also transport various equipment to the moon, mine lunar resources and transport them back to the earth.

At that time, the research on the controllable nuclear fusion technology of Earth and Star will also accelerate, and realize the impact of positive feedback in all aspects.

Under such circumstances, Xu Lei naturally did not need to stay in the hall of the Science and Technology Museum. He wanted to contact Wu Chuping as soon as possible to discuss the construction of a space elevator.

When Xu Lei regained consciousness, he immediately felt the softness coming from his head, and opened his eyes suddenly, only to see Xingtong's face reflected in his sight.

"Boss, you're awake." Seeing Xu Lei open his eyes, Xingtong hurriedly stopped his hands and greeted with a happy face.

Xu Lei has long been used to Xingtong's habit these days, and now his mind is full of space elevators, so he will definitely not delay Xingtong for too long, and he ordered, almost as soon as he sat up straight : "Contact Wu Chuping and ask him to come to my office as soon as possible."

"But the boss has only passed by for a few minutes, are you sure you don't want to wait any longer?" Facing Xu Lei's order, Xingtong did not directly execute it for the first time, but asked suspiciously.

Xu Lei seemed to have passed a long time in the science and technology museum, but in reality it was only a few minutes.

Previously, he had found an excuse to temporarily fool Wu Chuping, but the other party probably hadn't reached the research center yet, and at this moment he hurriedly asked him to come back.

Hearing Xingtong's reminder, Xu Lei was also full of embarrassment, and he was so focused on the space elevator that he forgot about it.

However, his emotions have been completely mobilized now, and if he had to wait for a few hours, it would definitely be unbearable.

So after a little hesitation, a decision was made.

"Let's inform him first. You can come over after visiting the research center."

"Good boss." This time, Xingtong didn't hesitate anymore, and at the same time, he directly cast a three-dimensional virtual figure in front of Wu Chuping's eyes, conveying Xu Lei's words on his behalf.

……

Similar to Xu Lei who was thinking about the construction plan of the sky elevator, Wu Chuping only wanted to persuade Xu Lei to join his project, at least not for nothing.

So after learning that Xu Lei had made a decision so quickly, his first reaction was that he agreed.

After all, this has already been said, if Xu Lei refuses, he will definitely not give an ultimatum in just a few minutes.

This doesn't fit the personality.

So after thinking that his plan was likely to succeed, he was in the mood to accompany Pei Hongyin to visit the research center, so he immediately turned around and returned to the headquarters building.

Although Pei Hongyin was a little dumbfounded about this, he did not dissuade Wu Chuping in this state, so he had to follow him to Xu Lei's office.

The two met again after a while, but their moods changed a lot.

Almost as soon as he opened the door and entered the office, Wu Chuping couldn't wait to say hello, "Academician Xu, have you agreed to go to the imperial capital to participate in the research of the manned moon landing project?"

Seeing Wu Chuping's state, to be honest, Xu Lei really couldn't bear to beat him, but the simple launch vehicle can't even surpass the overseas level, so how can he build a base on the moon in a short time.

Now that there is a better solution, we must choose the best one.

"Commander Wu, sit first." Xu Lei greeted Wu Chuping to sit down on the sofa next to him, and patiently organized his words: "Actually, I let you come back so soon because I have a new idea about manned moon landing, which may allow us to Take the lead in completing the construction of the moon base."

"New ideas?" Wu Chuping was taken aback, and his expression became calm, but he still asked out of politeness: "I don't know what new ideas Academician Xu is talking about?"

"I plan to build a space elevator and use a space elevator to replace traditional launch vehicles."

Space Elevator! ?
Xu Lei's words were earth-shattering, not only made Wu Chuping look a little dull, but even Pei Hongyin who was next to him widened his eyes.

Never thought that Xu Lei's thinking has reached the level of a space elevator.

After a short period of distraction, Wu Chuping understood why Xu Lei didn't agree to participate in the project before. The reason is that he didn't look down on traditional launch vehicles at all and wanted to challenge more difficult projects.

However, as the commander-in-chief of the lunar exploration project, how could Wu Chuping have never thought about a space elevator, but after everyone's research and discussion, they agreed that it was not feasible.

But he knew that Xu Lei was a person who never fought uncertain battles. If he didn't have a certain amount of confidence, he would never have mentioned something like a space elevator that only existed in movies.
