Military Technology

"In fact, there is no obvious hierarchical design between these functional modules, but for the convenience of later maintenance, we still adopt a modular design. This is convenient for later inspection and maintenance.

The control section is mainly the control center of the lunar lander, which is responsible for controlling the speed, attitude, and working time of the propellers of the entire lunar lander. It can only be said that it has a very powerful independent computing control capability, and it can also directly accept relevant instructions from the crew cabin for execution.

The resource storage segment, as the name suggests, is used to store related resources. For example, the fuel used in the landing and lift-off process of the landing and lift-off platform, as well as the oxygen, electricity and other resources used by the passengers in the crew cabin. This part occupies 70 to 80 percent of the space and weight of the entire landing and lift-off platform.

Next is the thruster. We installed five high-power vacuum engines at the bottom of the landing and lift-off platform to provide the recoil deceleration of the lunar lander during landing, and the thrust acceleration during the ascent phase. In addition, there are some small attitude adjustment engines on the landing and lift-off platform, which are used for the landing and landing stage, as well as the take-off and lift-off stage, as well as the attitude control work of the lunar lander during the in-orbit flight and docking process.

The design and manufacture of these engines basically refer to the engine technology of our Jianmu series of spaceships, so they can be used repeatedly. However, because the gravitational force of the moon is smaller, the pressure caused by the operation of the engine is relatively small, so it can greatly extend and improve the service life of these engines.

At the same time, these engines are also very easy to disassemble and replace, so as to facilitate later maintenance and repair work, and continue to extend the service life of the entire lunar lander, thereby greatly reducing costs.

Next is the landing gear, which is the legs of this lunar lander. Don't look at these legs, the technology is not low at all. It must maintain sufficient strength, high temperature, low temperature, impact resistance, good shock absorption and buffering capacity, and long-term use.

But the good thing is that we don't have to consider the effect of air resistance, because there is basically no atmosphere on the moon, so naturally there is no resistance. Therefore, we don't have too many concerns about this aspect in the design, so it is a relatively good design. However, it is still very difficult to develop and realize it. "

Hearing Zhou Xiangming's introduction, Wu Hao smiled and waved his hand: "Kung fu pays off, I believe that no matter how difficult it is, it will not be difficult for us. Come on, try to let me see it as soon as possible.

And we also plan to go to the moon for a vacation at that time. Don't let us down if you go. "

You can rest assured, I promise to let you go to the moon comfortably and have a pleasant vacation in our self-developed spacecraft. Zhou Xiangming said with a smile.

Wu Hao nodded, then continued to stare at the big screen for a while, then turned to Zhou Xiangming and asked: "By the way, once the lunar scientific research station is built, we need to transport a large amount of materials and equipment from the earth to the moon in the early stage. How do you think about waiting for this Earth-Moon transfer spacecraft and lunar lander?"

Hearing Wu Hao asking this question, Zhou Xiangming shook his head with a smile: "We also have related research and discussions in this regard. According to your request, if waiting for the Earth-Moon transfer spacecraft and lunar lander is too much time and progress, it is necessary to To choose a fast, convenient, and low-cost technical way.

Therefore, through repeated research and discussion, we finally decided to improve our existing technology, so as to integrate a more suitable technical solution for the transportation of earth-moon materials. "

Tell me in detail. Wu Hao nodded.

Yes. Zhou Xiangming slid the transparent folding tablet in his hand, and a new design schematic appeared on the big screen in front of Wu Hao and the others.

The earth-moon transfer carrying capacity of our Jianmu-9 rocket can reach about 20 tons, which can fully meet the material transfer needs of our lunar scientific research station in the early and mid-term construction. Therefore, we intend to use the strong transportation capacity of Jianmu to undertake the task of material transportation in the early and middle stages.

As for the orbit adjustment and deceleration, the orbiter is responsible for the orbiter, and the sky crane developed by us can be completely responsible for the landing and landing on the moon.

Sky crane? Zhang Jun was surprised.

Yes, Zhou Xiangming nodded and replied with a smile: "It is the sky crane technology that we successfully sent the 'Wangshu' intelligent lunar surface inspection rover to the moon. Since we can put the 'Wangshu' intelligent lunar surface inspection The rover is sent to the moon, so why can't we send these materials to the moon as well.

We have the technology, and we only need to make corresponding improvements at that time to adapt to larger and more weight and volume. According to preliminary calculations, we can transport about 10 to 12 tons of materials to the moon at one time. Such a carrying capacity is still very impressive. "

New flowers bloom on old technology, a good idea. Wu Hao praised with a smile.

From the current point of view, this technical solution can meet their current development needs. As for the cost, it is natural that the transportation cost of the earth-moon transfer spacecraft and the lunar lander will be higher than that in the future~www.readwn.com~ But this is the initial construction stage, which is unavoidable.

And they don't need to transfer all the materials from the earth. Eighty percent of the materials that Wu Hao and the others plan to build the lunar scientific research station will be sourced locally on the moon. They only need to transport related construction equipment and scientific research instruments. And some resources and materials that cannot be obtained on the moon.

To give a very simple example, rubber, organic matter, including the initial chemical energy fuel, etc., cannot be provided on the moon, and can only rely on the earth.

However, with the completion of the lunar scientific research station, the related operating resources in the later period will basically rely on the moon to provide, such as water, electricity, oxygen, and some food, etc., which can be obtained by using lunar resources.

There are also some that cannot be obtained on the moon, such as precision instruments, parts, some daily necessities, and even chemical products such as paper towels, shampoo and shower gel. And some supplies.

There are also some materials that can be provided on the moon, but they are not abundant. A very simple example, food. Although it is possible to grow food and vegetables on the moon in the later stage, and even cultivate some high-protein mealworms, 3D printing technology can also be used to print some meat to improve meals.

However, food is still too scarce and too monotonous relative to the earth. Therefore, for the physical and mental health of the members of the scientific research station, it is also necessary to regularly transport some abundant food from the earth to improve the meal and adjust the mood.
