Is this thing so difficult? Zhang Jun looked a little puzzled as he looked at the various design sketches passing by on the screen. Hearing Zhang Jun's words, Zhou Xiangming smiled bitterly and nodded: "It's much more difficult than we thought. Its development is no less difficult than the Earth-to-Moon transfer spacecraft. To a certain extent, it even exceeds the Earth-to-Moon transfer spacecraft. It is What is faced is a very dangerous landing and ascent work, and there is no room for any mistakes in this mission. If there is even the slightest deviation, the lander is likely to crash on the moon.

Although the gravity on the moon is very small, it can still kill people. Insan's Chandrayaan probe is a good example. "

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

While Wu Hao nodded, he looked at the sketches passing by on the big screen, and then asked Zhou Xiangming: "So which plan did you finally choose?"

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

As he spoke, he clicked on 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, turning into a three-dimensional model.

"This is our preliminary design of the lunar lander. It consists of two parts, the upper crew cabin and the lower power propulsion cabin. You may have noticed that the lunar lander Isn’t the appearance and structure a bit similar to our Walker manned spacecraft?”

Seeing Zhou Xiangming ask this question, many people at the scene nodded. Judging from the model, this lunar lander design model is very similar to their Walker manned spacecraft in appearance, but there are also obvious differences.

Zhou Xiangming was very satisfied with everyone's reaction, then nodded with a smile and said: "Yes, the design of this lunar lander draws on and uses 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 redesign has been carried out.

First of all, in terms of volume, the overall volume and mass of this lunar lander are much larger than the Walker manned spacecraft. Secondly, there are also big differences in functionality and technology.

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

It is an independent cabin, consisting of a crew cabin and an airlock. The crew cabin is the main structure, responsible for the transportation of personnel and materials for the entire lunar lander. The entire lunar lander can meet the transportation needs of ten and up to twelve members at a time.

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

As far as the current stage and the foreseeable future are concerned, this number of passengers is quite reasonable. "

After speaking, Zhou Xiangming looked at Wu Hao. Wu Hao also gave full affirmation. At present, the carrying capacity is still in line with his expectations. After all, the lunar scientific research station cannot accommodate too many people, so this kind of carrying capacity is sufficient. If you want to build a lunar city in the future, this is obviously not enough. Of course, that's in the future. At that time, they may have already developed a lunar lander with thirty, fifty, or even one hundred people.

After receiving Wu Hao's affirmation, Zhou Xiangming continued: "Due to the increase in crew members, the entire crew cabin is divided into upper and lower floors. The upper floor is the main control center, which can accommodate three to four crew members. It is the control center of the entire lunar lander. .

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

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

Don’t we, V, want the relevant precious resources on the moon? We can completely use this lunar lander to transport them in the early stage, including the golden meteorite we discovered before. "

This is good! Upon hearing this, Zhang Jun immediately clapped his hands and praised. Obviously Zhou Xiangming's words went deep into Zhang Jun's heart.

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

Zhou Xiangming smiled, and then continued: "We designed an airlock on the side of the crew cabin, which can facilitate personnel 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, this airlock is designed to facilitate future docking with the landing site corridor in the lunar scientific research station. In this way, the members in the crew cabin do not need to change into clumsy and expensive lunar landing spacesuits, exposing On the moon.

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

The biggest benefit of this is that it saves us a lot of lunar space suits. After all, we can't prepare so many lunar space suits as backup, and we have to take them to the lunar lander to go up and down the moon.

Secondly, this can reduce the pressure on the moon landing personnel, is very friendly to tourists, and is conducive to future commercial operations. "

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

This is the same as the escape and recoil rocket on the return capsule of our Walker manned spacecraft. We have applied this technology to the crew capsule. Its function is also to enable escape in an emergency, thereby ensuring the safety of the crew members in the cabin.

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

After the crew cabin lands, it will continuously send location distress signals for search and rescue personnel to locate.

The oxygen and fresh water food in the crew module can allow these crews to survive on the moon for more than twenty hours. This time can be provided to the search and rescue team of the lunar scientific research station for emergency rescue.
