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

The construction of the cable is to make the cable straight and avoid the cable hitting the ground. Therefore, the construction of this step must be carried out after the construction of the synchronous track station and the counterweight is completed.

Ye Fan's plan is to split the cable into many sections, then hang them down on the synchronous track station and connect them in sequence.

Therefore, in order to achieve fixed and continuous extension, 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 lower angle is called during the construction period, the cable will have different angular speeds, which will deviate from the axis and even destroy the entire structure.

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

After the ground station and the cable, there is the problem of synchronous orbital stations.

The construction difficulty of the synchronous orbital station is the lowest among all parts, because the synchronous orbital station is located in the geostationary orbit (GEO), which is convenient to fix the location. The part in space should be constructed from the synchronous orbital station.

Its function is similar to that of a ground station. It has to perform the functions 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 cars, release cars, install dampers, and most importantly carry out space activities, such as space research, launching detectors, etc.

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

If the third batch of mining spacecraft does not return, even with the current technology of mankind, all the rocket engine pressure box bottom technology will be taken out, and the construction of this project will be far away.

Taking into account the various loads of the synchronous orbit station, it is estimated that its mass should be at least 20 to 30 times that of the ISS, which is 8000-12000 tons. With the current launch capacity, at least 200 launches are required to build a synchronous orbit station. .

If we rely solely on today’s fossil fuel rockets, according to the 2018 launch records of NASA (including private companies), China Space Agency, European Aviation Agency and the Russian Federal Space Agency (31, 39, 11, 19, heavy-duty) Rockets do not exceed 10 times) If you look at it, it will take at least ten years to complete.

So if Ye Fan did not get the system and did not promote technological progress, even mankind would develop a 100-ton GEO rocket in the next 20 years. Under the more intensive launch plan, the synchronous orbital station The construction cycle of the project will take less than five years.

For such a long time, human beings cannot afford to wait.

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

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

The counterweight can be equipped with functional modules that are not easy to build, such as large-area solar panels, which are required by synchronous rail stations.

After all, it is currently impossible to carry a nuclear fusion reactor, so except for the 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 spacecraft.

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

The environment in space is extremely complicated, and the construction and maintenance of the two synchronous orbital stations is also very difficult. It is better to do a good job in the space elevator, and then after building a number of space mining spacecraft, develop space heavy industry at the remote end Plant to produce related rare metals and materials.

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

Don't look at the thing like 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 counterweights.

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

And to ensure that its ascent speed is not too fast, otherwise the occupants in the car will die because of atmospheric friction, or because of too much G overload.

At the same time, when descending, a certain speed must be maintained. It is necessary to ensure that the time is rapid, but also to maintain a reasonable speed. Otherwise, the car is no different from a meteorite hitting the ground directly.

At present, there are two solutions to Origin, which is to install related thrust-increasing equipment under the car like a rocket to push the car up.

The anti-gravity engine was the first to be ruled out. After all, the size of the anti-gravity engine is very large. At present, with the strength of Datang Technology, it has not been possible to miniaturize it. The most important issue is its ascent speed. too slow.

The anti-gravity engine method is mainly due to its heavy weight and slow lift-off speed. In addition to these two shortcomings, its balance is stable, and it can be as stable as Mount Tai at an altitude of 10,000 meters. This is not comparable to other engines, but it is bulky. And the two points of slow speed are enough to rule out the anti-gravity engine~www.wuxiaspot.com~ After all, today's anti-gravity engine is still in the first generation, even if it is a synchronous orbital station, it can apply relevant pulling force to it to accelerate its rise. It also takes at least eight hours to reach the atmosphere.

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

And fossil fuel engines are unrealistic. After all, space elevators can be reused. If you build a fossil fuel engine with a large fuel tank on your back, although the volume is much smaller, it has no practical application value.

So at present, this focus is on the ion engine. After the third batch of mining spacecraft returns, the thrust provided by the third-generation ion engine is enough to push related equipment out of the atmosphere, and it can maintain a proper speed.

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