"Actually, there is no very obvious hierarchical design between these functional modules, but for the convenience of later maintenance, we still adopt a modular design. This facilitates later inspection and maintenance.
The control section is mainly the control center of the lunar lander, which is responsible for controlling the speed, attitude, thruster working time, etc. of the entire lunar lander. All I have to say is that it has very powerful independent computing and control capabilities, and at the same time, it can also directly accept relevant instructions from the crew cabin for execution.
Resource storage segment, as the name suggests, is used to store related resources. For example, the fuel used by the landing and lift-off platform during the landing and lift-off process, as well as the oxygen, electricity and other resources used by the passengers in the crew cabin. This part occupies 70-80% 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 this landing and ascent platform to provide recoil deceleration when the lunar lander lands and thrust acceleration during the ascent stage. In addition, there are some small attitude adjustment engines on the landing and lift-off platform, which are used for the landing and landing phases, the take-off and lift-off phases, and the attitude control of the lunar lander during the on-orbit flight and docking process.
The design and manufacture of these engines basically refer to the engine technology of our Jianmu series spacecraft, so they can be recycled and reused. However, because the moon's gravity is smaller, the pressure on the engine is relatively small, so the service life of these engines can be greatly extended and improved.
At the same time, these engines are also very convenient to disassemble and replace, so as to facilitate later maintenance and repair work, continue to extend the service life of the entire lunar lander, thereby greatly reducing costs.
Next is the landing frame, which is the legs of the lunar lander. Regardless of just these legs, his skills are not low at all. It must maintain sufficient strength, be resistant to high temperatures, low temperatures, and impact, have good shock-absorbing and buffering capabilities, and must be suitable for long-term use.
But one good thing is that we don't have to consider the impact of air resistance, because there is basically no atmosphere on the moon, so there is naturally no resistance. Therefore, we don’t have too many concerns in this regard in the design, so it is a relatively good design. However, it is still very difficult to develop and implement it. "
Hearing Zhou Xiangming's introduction, Wu Hao smiled and waved his hand: "Kung Fu pays off, I believe no matter how difficult it is, we can't beat it. Come on, try to let me see it as soon as possible."
And we also plan to go to the moon for vacation, please go there and don’t let us down. "
Don’t worry, when the time comes, I guarantee that you will be able to board our self-developed spacecraft and go to the moon for a comfortable and enjoyable vacation. 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 will need to transport a large amount of materials and equipment from the earth to the moon in the early stage. What are your thoughts on waiting for the Earth-to-Moon transfer spacecraft and lunar lander?"
Hearing Wu Hao ask this question, Zhou Xiangming smiled and shook his head: "We also have relevant research and discussions in this area. According to your request, waiting for the Earth-to-Moon transfer spacecraft and lunar lander will waste too much time and progress, so we must Choose a technical method that is fast, convenient, and low-cost.
Therefore, through repeated research and discussion, we finally decided to improve our existing technology and integrate a more suitable technical solution for the transportation of earth-to-lunar materials. "
Talk about it in detail. Wu Hao nodded.
yes. Zhou Xiangming slid the transparent folding tablet in his hand, and a new design diagram appeared on the big screen in front of Wu Hao and others.
The Earth-to-Moon transfer carrying capacity of our Jianmu-9 rocket can reach about 20 tons, which can fully meet the material transfer needs for the early and mid-term construction of our lunar scientific research station. Therefore, we plan to use Jianmu’s strong transportation capabilities to undertake the material transportation tasks in the early and mid-term.
As for the orbit adjustment, deceleration and orbiting work, it is left to the orbiter, and the landing on the moon can be completely left to the sky crane we developed.
Sky crane? Zhang Jun said in surprise.
Yes, Zhou Xiangming smiled and nodded: "It is the sky crane technology that successfully sent the 'Wangshu' intelligent lunar surface patrol vehicle to the moon. Since we can put the 'Wangshu' intelligent lunar surface patrol vehicle The rover was sent to the moon, so why can't we also send these materials to the moon.
We have the technology, we just need to make corresponding improvements when the time comes to adapt to greater weight and volume. According to preliminary calculations, we can transport about ten to twelve tons of materials to the moon at one time. This kind of carrying capacity is still very impressive. "
It's a good idea to put new flowers on old technology. Wu Hao smiled and praised.
For now, this set of technical solutions can meet their current development needs. As for the cost, it is naturally more expensive than future Earth-to-Moon transfer spacecraft and lunar landers, but this is the initial construction stage and is unavoidable.
And not all their materials need to be transported from the earth. Eighty percent of the materials Wu Hao and his team plan to build the lunar scientific research station will be sourced locally on the moon. They only need to transport relevant construction equipment and scientific research instruments. As well as some resources and materials that are not available on the moon.
To give a very simple example, rubber, organic matter, including early chemical energy fuels, etc. cannot be provided by the moon and can only rely on the earth.
However, with the completion of the lunar scientific research station, related operational resources in the later period will basically be provided by the moon, such as water, electricity, oxygen, and some food, etc., which can be obtained using lunar resources.
There are also some things 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. There are also some supplies.
There are also some supplies that can be provided on the moon, but are not abundant. A very simple example, food. Although food and vegetables can be grown and cultivated on the moon in the future, and some high-protein mealworms can even be cultivated, 3D printing technology can also be used to print some meat and improve food.
However, compared to the earth, food is still too scarce and too monotonous. Therefore, for the physical and mental health of the members of the scientific research station, it is necessary to regularly transport some abundant food from the earth to improve the food and adjust the mood.
