Vol 2 Chapter 2091: A new approach to lunar landing technology

Is this thing so difficult? Looking at the sketches of various design schemes that swept across the screen, Zhang Jun was a little puzzled. Hearing Zhang Jun's words, Zhou Xiangming nodded with a wry smile: "It's more difficult than we thought, and its development is no less difficult than this Earth-Moon transfer spacecraft. It even exceeds the Earth-Moon transfer spacecraft to a certain extent. It is a very dangerous landing and ascent job, and there is no room for error in this mission. If there is any deviation, the lander is likely to crash on the moon.

Although it is said that the gravitational force on the moon is very small, it can also fall to death. Yinsan's Chandrayaan probe is a good example. "

After listening to Zhou Xiangming's introduction, everyone at the scene nodded.

While nodding, Wu Hao looked at the sketches on the big screen, and then asked Zhou Xiangming, "So you finally chose that plan."

Seeing Wu Hao asking this question, everyone's attention was focused on Zhou Xiangming. Zhou Xiangming smiled, then slid over a design sketch and stopped, and said to the crowd, "This is the preliminary design sketch we have determined after thorough research and demonstration."

Saying that, he clicked the transparent folding tablet in his hand, and the image of the lunar lander in the sketch on the big screen jumped out of the sketch and floated in the air, becoming a three-dimensional model.

"This is the lunar lander we have initially designed. It consists of two parts, the upper crew compartment and the lower power propulsion compartment. You may have noticed that the lunar lander has two parts. Is the shape and structure a bit similar to our Walker manned spacecraft?"

Seeing Zhou Xiangming's question, many people at the scene nodded their heads one after another. Judging from this model, this model of the lunar lander design scheme is very similar to their Walker manned spacecraft, but there are also obvious differences.

Zhou Xiangming was very satisfied with everyone's response, and then nodded with a smile: "Yes, the design of this lunar lander has borrowed and used the mature design of the Walker manned spacecraft to a certain extent. Of course, we will also According to different tasks and different environments, targeted redesigns have been carried out.

First of all, in terms of volume, the size and mass of this lunar lander are more than that of the manned spaceship. Second, in functionality, technology is also very different.

Let's talk about the crew capsule on the lunar lander first. You can think of it as or understand it as the manned return capsule on our Walker manned spacecraft.

It is an independent cabin, composed of two parts: the crew cabin and the airlock cabin. Among them, the crew cabin is the main structure, which undertakes the personnel and material transportation tasks of the entire lunar lander. The entire lunar lander can meet the transportation needs of ten people and a maximum of twelve members at one time.

Of course, in the future, we will design and develop lunar landers with more members, such as 20, 30, or even 50 large lunar landers based on the needs of our mission, to Meet more people and material transportation needs.

As far as the first stage and the future can be seen for a period of time, this number of people is still relatively reasonable. "

After speaking, Zhou Xiangming looked at Wu Hao. As for Wu Hao, he also gave full affirmation. For now, this carrying capacity is still in line with his expectations. After all, the lunar scientific research station cannot accommodate too many people, so such a carrying capacity is sufficient. If you want to build lunar cities in the future, this is obviously not enough. Of course, that is the future. At that time, maybe they had already made a lunar lander with a size of thirty, fifty, or even a hundred people.

With Wu Hao's affirmation, Zhou Xiangming continued: "Because of the increase in the number of crew members, the entire crew cabin is divided into upper and lower layers, and the upper layer is the main control center, which can accommodate three to four crew members and is the control center of the entire lunar lander. .

The lower deck is the main crew cabin, which can accommodate six to eight people. Of course, these tables and chairs can also be removed to store related materials and equipment. That is to say, we have considered the mission needs for a long time in the future, so we have designed a lunar lander that can accommodate both personnel and cargo transportation.

In this way, it is feasible to transport personnel and materials from orbit to the moon, or transport related materials and personnel from the moon to orbit.

Don't we want related precious resources on the moon? We can use this lunar lander for transportation in the early stage, including the golden meteorite we discovered before. "

This is good! Hearing this, Zhang Jun immediately applauded. Obviously, Zhou Xiangming's words came into Zhang Jun's heart.

Wu Hao glanced at him angrily, then motioned for Zhou Xiangming to continue.

Zhou Xiangming smiled, and then continued: "We designed an airlock cabin on the side of the crew cabin, which is convenient for people to enter and exit on the moon. After all, if it is on the moon, it is really difficult to enter and exit through the docking port on the top of the crew cabin. So inconvenient.

In addition, the design of this airlock is also for the convenience of docking with the landing field corridor in the lunar scientific research station in the future, so that the members of the crew module do not need to change into clumsy and expensive space suits for landing on the moon. on the moon.

It is completely possible to pass through the docking corridor and then directly enter the lunar scientific research station.

The biggest advantage of this is that it saves us a lot of lunar space suits. After all, it is impossible for us to prepare so many lunar space suits for backup, and we have to bring them to the lunar lander to go up and down the moon.

Secondly, this can reduce the pressure on the lunar landing personnel, which is very friendly to tourists~www.readwn.com~ is conducive to future commercial operations. "

Speaking of this, Zhou Xiangming zoomed in on the model on the screen, and then continued to speak to the crowd: "I believe everyone has noticed that there are also four fins on the outside of this crew cabin.

This is the same as the escape and recoil rockets on the return capsule of our Walker manned spacecraft, and we have applied this technology to the crew capsule. Its function is also to escape in an emergency, so as to ensure the safety of the members of the cabin.

Whether it is performing a landing and landing mission or a take-off and take-off mission, when the thruster under the lunar lander fails and cannot work normally. The escape system immediately activates the escape rockets hidden under the four fins. The crew module will quickly disengage from the landing propulsion platform below, and then control the crew module to land safely on the moon.

After the crew cabin hits the ground, it will continuously send a positional distress signal for search and rescue personnel to find and locate.

Oxygen and fresh water food in the crew capsule will be able to accommodate these members for more than twenty hours on the moon. And this time can be provided to the search and rescue team of the lunar scientific research station for emergency rescue. "
