"And more engines mean higher redundancy, which is a very advanced safety design. Whether it is landing on the moon or ascending from the lunar surface to the lunar orbit, although it is less than 20,000 meters, the whole process is very It is dangerous and cannot tolerate any mistakes. Otherwise, it may have to smash holes in the moon like the lunar probe of a large country in the southern subcontinent. So there are more engines, which means that even if the entire landing is And during the ascent process, one or two of the engines failed, which will not affect the flight of the lunar surface transfer spacecraft."...
"Just like a multi-axis propeller drone, even if one or two motors fail, it will not affect the normal flight of the entire drone. As for the capsule tank under the cantilever that surrounds the entire lander , these are the fuel tanks of the entire lunar surface transfer spacecraft, which are filled with relevant propulsion fuel required for the engine of this lunar surface transfer spacecraft. They are mainly liquid oxygen and liquid hydrogen. As we all know, these two can be decomposed in water. Obtained. The liquid oxygen and liquid hydrogen engine is also the mainstream engine of the current launch vehicle, and it is very reliable in terms of technology. As for these yellow structures, this is the landing rack system of this lunar surface transfer spacecraft, which plays the role of the entire lunar surface transfer spacecraft. The landing, buffering and supporting structure of the lunar surface transfer spacecraft. It has a very powerful buffering function, which can reduce the impact of the lunar surface transfer spacecraft during the landing process, thus ensuring the safety of the lunar surface transfer spacecraft and the people inside it. Very low. In addition, the landing gear support system also has the ability to adapt to different terrains and terrains, and can keep the entire lunar surface transfer spacecraft stable. Of course, its smallest feature Still under the heavy stool, you use titanium alloy materials. Yes, while being heavy, it can also maintain sufficient strength and toughness to meet the requirements of long-term use." However, there are not so few requirements for transporting goods, and the smallest The requirement is very high to transport as little cargo as possible.
Seeing the seven people nodding in appreciation, Yu Chengwu continued: "Therefore, just like your Walker manned spacecraft, the crew cabin under the lunar surface transfer spacecraft cannot accommodate at least four crew members. That is also the same as your Walker manned spacecraft. The carrying capabilities of human spacecraft are equivalent and cannot achieve perfect connection between manned missions.
"Above the crew cabin is an airlock cabin, which cannot be called the lunar landing preparation cabin. It is an independent cabin section, and there is no airlock door separating it from the crew cabin. The space in the airlock cabin is very abundant. You cannot place a few lunar spacesuits, nor can you use it to store some supplies or cargo. Therefore, you have retrograded the planning and design of the interior of the crew cabin. For example, the crew seats inside the crew cabin are all removed, so that Free up the minimum space to transport cargo and supplies. In addition, you have also designed multiple cargo hanging points around the cabin, including above, to mount and transport some over-long and over-small cargo, increasing the number of transshipments on the lunar surface. The cargo carrying capacity of the spacecraft. Here, there is an elevator at the bottom of the airlock. It cannot be opened directly to the moon surface, so it cannot transport some overweight cargo. Of course, astronauts cannot exit through that elevator. Airlock." There are two doors in the airlock, one is the main door on the side.
The main door is relatively narrow, making it easy for the crew to exit nervously. Of course, it is also convenient for transporting some cargo.
Those seat covers are all designed with slow disassembly, which is very convenient for disassembly and installation. "What's above the docking port is not the crew cabin. Its internal structure is actually the same as the interior of the crew cabin of your Walker manned spacecraft.
After all, there will be frequent exchanges between the earth and the moon in the future, and the operation of the Zhihai Lunar Surface Scientific Research Station will require a small amount of material supplies.
Although some supplies cannot be solved on the moon, few supplies can be obtained and produced under the moon and can only be transported from the earth.
"It needs to be explained!" Yu Chengwu said softly to the seven people: "The lunar surface transfer spacecraft is a transfer spacecraft with few functions. It does not mean that it can neither carry people nor be used for transportation. Cargo. At this time, you must still use your lunar cargo transfer spacecraft, the cost is too low. So at this time, use the lunar surface transfer spacecraft to cooperate with the Lunar Slow-Earth transfer spacecraft and the Walker manned cargo spacecraft, It will not be possible to realize the ultra-high-cost transfer of personnel and cargo. It only saves time and effort, and the smallest advantage is very low money. And when carrying people, you cannot install those removed seats back into the passenger cabin. Therefore, it can be used to carry people. After hearing Yu Chengwu's introduction, Wu Hao and Zhang Jun nodded. Indeed, that is indeed a bad idea. It will save very little scientific research funds, and it can also shorten the development time and speed up the development process. The project has been regressed, which can be said to be a small achievement with one stone. Here, the control system of the entire lunar surface transfer spacecraft is also in the crew cabin. Like the Walker manned spacecraft, it is very intelligent. The entire process cannot be fully automated and autonomous. Retrograde intervention is required. In fact, the entire lunar surface transfer spacecraft is divided into eight parts from bottom to top. The bottom one is not a docking device and cannot be ridden in the docking port. It is used to dock with the Lunar Slow Earth-lunar transfer spacecraft. Itself The seven technologies are also common among them. Doing so can save scientific research funds and shorten the development process to a small extent, and it is also a full use of resources and technology." Of course, in ordinary situations, it is necessary to During the intervention, the members were unable to precisely control the entire lunar surface transport spacecraft's movement through several screens and physical buttons in the crew cabin.
The entire crew cabin is in a sealed state, except for the upper and lower entrances and exits, which cannot be completely closed, forming a completely sealed space.
The life support system of the entire lunar surface transfer spacecraft cannot support the survival of four astronauts for at least seven days.
"That is the push-back landing system, and what is outside is the main body of the lunar surface transfer spacecraft, the manned crew module and the docking device below. That way, if the lunar surface transfer spacecraft is landing or ascending If something unexpected happens during the process, we must not lack enough time to carry out the rescue and ensure the survival of the crew members in the cabin to the minimum extent." Just like your Walker manned spacecraft, the entire crew cabin is very narrow and comfortable, and can be minimized Improve the ride comfort of the passengers to a certain extent.
Therefore, when designing, you fully considered the needs of carrying people and cargo.
For example, personnel need to be ensured and the minimum comfort of the occupants must be ensured. In other words, the crew module of the lunar surface transfer spacecraft was not modified based on the crew module technology of the Walker manned spacecraft.
