Therefore, the interface of the cable can be changed along with the radius of the orbit, so that the cable reaches a structure that gradually becomes thinner from the synchronous orbit station to the ground.

The purpose of building the cable is to straighten the cable and prevent the cable from hitting the ground, so this step of the project must be carried out after the construction of the synchronous orbit station and the counterweight is completed.

Ye Fan's plan is to split the cable into many pieces, hang them down from the synchronous orbit station, and connect them in sequence.

Therefore, in order to achieve fixation and continuous elongation, the specific construction plan can refer to the self-elevating tower top mechanism of the tower crane.

However, it seems simple, but in fact there is a problem, that is, when the construction cycle is carried out at a relatively low angle, the cables will have different angular velocities, which will deviate from the axis and even destroy the entire structure.

Therefore, it is necessary to set up a long-term resident near-space vehicle as an observation station, and at the same time limit and correct the cables, and Ye Fan's space-based weapons can be modified to complete this task.

After the ground station and the cable, there is the problem of the geosynchronous orbit station.

The construction difficulty of the geosynchronous orbit station is the lowest in all parts, because the geosynchronous orbit station is located in the geostationary orbit (GEO), which is convenient for fixed positions, and the part in space should start from the geosynchronous orbit station.

Its function is similar to that of the ground station, and it must perform the function of a port, except that one is a ground port and the other is an air port.

At the same time, it also needs to store the car, release the car, install the damper, and most importantly carry out space activities, such as space research, launch of detectors, etc.

The scale of this construction is very large, but because it is in a proper synchronous orbit and in a balanced state, it does not have a great impact on the overall part.

If the third batch of mining spacecraft does not return, even with the current technology of human beings, if all the technology of the bottom of the rocket engine is taken out, it is still far away to build this project.

Considering the various loads of the synchronous orbit station, it is estimated that its mass must be at least 20 to 30 times that of the ISS, that is, 8,000-12,000 tons. With the current launch capacity, at least 200 launches are required to build a synchronous orbit station. .

If only relying on today's fossil fuel rockets, according to the launch records of NASA (including private companies), China Space Agency, European Space Agency and Ross Federal Space Agency in 2018 (31 times, 39 times,

11 times, 19 times, of which heavy rockets do not exceed 10 times), it will take at least ten years to complete.

Therefore, if Ye Fan does not get the system and does not promote scientific and technological progress, even if mankind develops a rocket with a 100-ton GEO carrying capacity within the next 20 years, under a more intensive launch plan, the synchronous orbital station The construction period of the project needs to be less than five years.

Human beings cannot afford to wait for such a long time.

In the entire space elevator project, the more difficult point is the problem of the counterweight. The difficulty of its construction lies in how to connect with the synchronous orbit station and how to maintain synchronization with the synchronous orbit station after the connection.

The counterweight is located at the far end on the axis of the synchronous orbital station, and its distance to the synchronous orbital station is determined by the quality of the cable from the synchronous orbital station to the ground, its own quality and the tension that the ground can provide. e-bookstore

The counterweight can carry some functional modules that are required by synchronous orbit stations, but are not easy to build, such as large-area solar panels.

After all, it is currently impossible to move the nuclear fusion reactor up, so except for very large spacecraft, the rest of the spacecraft rely on their own super batteries to provide electricity, or install solar panels to collect stellar energy. Improve the endurance of the spaceship.

As for the counterweight, it can also be used as a synchronous orbital station by itself, but this synchronous orbital station is relatively far away.

The environment in space is extremely complicated, and the construction and maintenance of two synchronous orbital stations are also very difficult. It is better to build a space elevator, and after building a batch of space mining spacecraft, carry out space heavy industry at the remote end Plants to produce related rare metals and materials.

The last difficulty in the space elevator project is the car.

Don't look at this thing as the cabin of the elevator, it seems to have no technical content, but in fact the difficulty of building this thing is no less than that of the counterweight.

The biggest problem with the car is how to ascend and how to increase the tangential speed during the ascent.

And it must be ensured that its rising speed cannot be too fast, otherwise the occupants in the car will die due to atmospheric friction, or due to too much G overload.

At the same time, when descending, it is necessary to maintain a certain speed. It is necessary to ensure that the time is fast and at the same time maintain a reasonable speed. Otherwise, the car is no different from a meteorite that hits the ground directly.

At present, Origin has two solutions, that is, like a rocket, install related thrust-increasing equipment under its car to push the car up.

The anti-gravity engine is the first to be ruled out. After all, the anti-gravity engine is very large. At present, with the strength of Datang Technology, it is still impossible to miniaturize it. The most important problem is its rising speed. too slow.

The anti-gravity engine method is mainly because of its bulkiness and slow lift-off speed. Apart from these two shortcomings, its balance is stable, and it can be as stable as Mount Tai at an altitude of 10,000 meters. It is not comparable to other engines, but it is bulky The two points of speed and slowness are enough to rule out the anti-gravity engine.

After all, today's anti-gravity engine is still in the first generation. Even if the synchronous orbital station can exert relevant pulling force on it and accelerate it to rise above the atmosphere, it will take at least eight hours.

For such a long time, it is a bit difficult to give away, and it can only be used to deliver goods or something.

Fossil fuel engines are unrealistic. After all, space elevators can be reused. If you use a fossil fuel engine and carry a large fuel tank, although the volume is much smaller, it has no practical value at all.

So now we are focusing on the ion engine. After the third batch of mining spaceships come back, the thrust provided by the third-generation ion engine is enough to push the relevant equipment out of the atmosphere, and it can also maintain a suitable speed.

However, there is a problem with this method, that is, since the angular velocity remains constant, the linear velocity will continue to increase as the radius increases during the ascent.
