Military Technology

“Therefore, we believe that this stepped approach to the moon is more in line with our needs.

If the moon landing plan is divided into three steps, then at present, we have solved this part of the technology to successfully send people into space. Our Walker manned spacecraft has successfully sent people into space.

So what we are going to do next is the second and third parts, and this earth-to-moon transfer spacecraft is mainly prepared for the second part of the earth-to-moon transfer transportation.

The so-called Earth-moon transfer spacecraft should not be regarded as a spaceship, but as a space station. It's just that the orbit of this space station is quite special. It sails between the earth and the moon.

With the help of the gravity of the Earth and the Moon, the Earth-Moon transfer spacecraft orbits in a figure-8 shape. Constantly traveling back and forth between the earth and the moon, responsible for the transportation of people and materials.

Why is it so similar to the core module of the space station? The main reason is that their functions are basically similar, but their uses are different.

"Everyone, please take a look!" Zhou Xiangming introduced the model of the Earth-to-Moon transfer spacecraft in front of everyone and said: "Similar to the core module of the space station, this Earth-to-Moon transfer spacecraft is also divided into large column sections and small column sections. The node cabin is composed of three parts.

The overall structure of this connection is the same, but the details are different. For example, the large column section of our Earth-to-Moon transfer spacecraft is relatively long, while the small column section is relatively short. The length ratio of the two is different. .

Secondly, there are a total of four solar cell sails on this Earth-to-Moon transfer spacecraft, whose main purpose is to provide power to the spacecraft.

A large part of the electricity will be used for the high-power Hall ion thrusters at the tail of the Earth-to-Moon transfer spacecraft. The Earth-to-Moon transfer spacecraft will rely on these Hall ion thrusters in the future to maintain its orbit.

In addition, there are ordinary fuel thrusters, which will be used for orbit changes and on-orbit maneuvers.

Although this Earth-lunar transfer spacecraft is only responsible for transporting materials and personnel, we have reserved an exit hatch on its node module at the same position as the core module of the space station. Its main purpose will be to carry out some exposure experiment missions in the deep space of the Earth and the Moon, as well as external maintenance tasks of the Earth-to-Moon transfer spacecraft, thereby extending its on-orbit service life.

Similarly, in order to assist in unloading and maintenance tasks, as well as on-orbit docking tasks, we have also specially equipped a seven-meter robotic arm. This robotic arm also has the ability to crawl on the surface of the spacecraft. Similarly, we have also given it a lot of intelligence. Relying on the artificial intelligence system, it can complete many tasks independently. Including some extravehicular maintenance work in orbit, thus greatly reducing astronauts’ activities on and off orbit. "

With that said, Zhou Xiangming led everyone to the tail of the Earth-to-Moon transfer spacecraft, and then continued to introduce it to everyone.

“Like the core module of the space station, we also retain a docking port at the tail of this Earth-to-Moon transfer spacecraft for the docking of cargo spacecraft.

Why should we retain this tail docking port? Mainly because our Earth-to-Moon transfer spacecraft needs to operate in orbit for a long time, so we need to continuously replenish fuel and materials for this Earth-to-Moon transfer spacecraft to maintain it in orbit for a long time. rail operating conditions.

At the same time, relying on the power of the cargo spacecraft, we also need to use the propeller of the cargo spacecraft to serve as the source of power for the Earth-to-Moon transfer spacecraft to promote the Earth-to-Moon transfer spacecraft to maintain a stable orbit. "

"Why is it so troublesome? Can't you just use the thruster on the Earth-to-Moon transfer spacecraft?" Zhang Jun interrupted Zhou Xiangming at this time and asked.

Hearing Zhang Jun's words, Zhou Xiangming said with a smile: "Of course it can be used, but blindly using the thrusters on the Earth-to-Moon Transfer Spacecraft will greatly reduce the on-orbit life of the spacecraft. After all, even if No matter how good the propeller is, it has a service life and needs to be used once and less often.

And if the thrusters on the cargo spacecraft are used to push the Earth-to-Moon transfer spacecraft, the on-orbit operating life of the spacecraft can be greatly extended. When the fuel on the cargo spacecraft burns out, it will separate from the Earth-to-Moon transfer spacecraft, and then choose to fall into the atmosphere and burn up, or let it crash into the moon in a controlled manner, so as to avoid generating too much space junk in orbit.

In this way, we can fully deploy the cargo spacecraft, thereby greatly reducing operating costs, thereby reducing the cost of transferring materials and personnel between the earth and the moon. On the one hand, this can meet the needs of our further lunar exploration missions, and on the other hand, it also lays a very good foundation for our commercial development of the moon. "

continue. Wu Hao nodded and then motioned for him to continue.

Zhou Xiangming understood, and then led everyone to the front of the Earth-to-Moon transfer spacecraft, and then said to everyone: "Similar to the core module of the space station, this is the node module of this Earth-to-Moon transfer spacecraft. It also has up, down, left, right, and front and rear five The rear interface is connected to the Earth-Moon transfer spacecraft, and the upper interface is reserved as an exit hatch. In the future, it can also be transformed into a docking interface in orbit to dock with other spacecraft, such as special airlocks, etc.

As for the docking ports on both sides, the docking ports are reserved for idle use and are used to dock with some other spacecraft. We plan to install a bubble-type panoramic space capsule on its left and right sides in the future for on-orbit scenic sightseeing and on-orbit space observation.

Another time, it can be docked with some experimental cabins, or it can be docked with an on-orbit astronomical patrol mirror. This depends on future needs and choices.

As for the front docking port, it is the main docking port of the Earth-to-Moon transfer spacecraft. It is mainly used for the docking mission of the manned spacecraft. The lower docking port serves as the docking port for the lunar lander. These two ports can be used interchangeably. "

After listening to Zhou Xiangming's introduction, Zhang Jun nodded, and then said thoughtfully to Wu Hao and Zhou Xiangming: "In other words, if we want to land on the moon, we need to take our Walker manned spacecraft to go there first. In space, it orbits the Earth, and then takes the opportunity to dock with the Earth-to-Moon transfer spacecraft that flies around the Earth from the lunar orbit.

After the docking is completed, we can transfer from the spacecraft to the Earth-Moon Transfer Spacecraft to carry out relevant modifications and preparations before landing on the moon.

When the Earth-to-Moon transfer spacecraft flies to the lunar orbit and flies around the moon, the lunar lander on the moon lifts off and then docks with the Earth-to-Moon transfer spacecraft. We then transfer it from the spacecraft to the lunar lander, and then it is called the lunar lander and lands on the moon, right? "

Hearing Zhang Jun's understanding, Zhou Xiangming and the others smiled and nodded in agreement: "You understand correctly, it's roughly like this."

"This is too troublesome." Zhang Jun frowned and shouted after hearing this. Remember the website address of this website, www. Biquxu． Com for easy reading next time, or enter " " in Baidu to enter this site
