Chapter 3071: Technical reuse of the Walker manned spacecraft
【Revision】
…
"Just like a multi-rotor drone, even if one or two motors fail, it will not affect the normal flight of the entire drone.
As for the capsule-shaped tanks that surround the entire lander under the cantilever, these are the fuel tanks for the entire lunar surface transfer spacecraft, which are filled with the relevant propulsion fuel required by the lunar surface transfer spacecraft engine.
There are mainly two types: liquid oxygen and liquid hydrogen. As we all know, these two can be decomposed in water. The liquid oxygen and liquid hydrogen engine is also the mainstream engine of current launch vehicles, 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. It serves as the landing, buffering, and support structure for the entire lunar surface transfer spacecraft. It has a very powerful buffering function, which can reduce the impact of the lunar surface transfer spacecraft.
The impact generated by the lunar surface transfer spacecraft during the landing process ensures the safety of the lunar surface transfer spacecraft and the people inside it.
In addition, this landing gear support system also has the ability to adapt to different terrains and terrains, allowing the entire lunar surface transfer spacecraft to remain stable at all times.
Of course, its biggest feature is its lightness. We use titanium alloy material, which is not only light but also maintains sufficient strength and toughness to meet the requirements of long-term use."
"This is the propulsion landing system, and what's inside is the main body of the lunar surface transfer spacecraft, the manned crew module, and the docking device on it.
In fact, the entire lunar surface transfer spacecraft cannot be divided into eight parts from bottom to top. The bottom part is connected to the docking device and cannot be ridden in the docking port. It is used for docking with the Lunar Slow Earth-lunar transfer spacecraft.
As a result, it cannot meet the increasing demand for transportation of personnel and materials.
It is not even possible to use two lunar surface transfer spacecrafts at one time to transport personnel and materials, thereby matching the minimum transportation capacity of the Lunar Slow-lunar surface-lunar transfer spacecraft."
After hearing Yu Chengwu's introduction, Wu Hao and Zhang Jun nodded. Indeed, it was indeed a bad idea. It would not only save very little scientific research funds, but also shorten the development time and slow down the project progress. It can be said that it is
One little thing achieved with one action.
In this way, if something unexpected happens to the lunar surface transfer spacecraft during landing or ascent, there will not be enough time to carry out rescue and ensure the survival of the crew members in the cabin to the minimum extent."
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, and requires retrograde intervention throughout the process.
Therefore, you have regressed the planning and design of the interior of the crew cabin. For example, the crew seats inside the crew cabin cannot be removed, so as to free up minimum space for loading cargo and supplies.
The entire crew cabin is in a sealed state, with only the upper and lower entrances and exits. It 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.
time.
The seven technologies themselves are also technically common. This will not save scientific research funds to a small extent and shorten the development process, but it is also a full use of resources and technology."
Here, there is an elevator at the bottom of the airlock cabin. It cannot be opened directly to go up to the moon surface, so it cannot transport some overweight cargo. Of course, astronauts cannot exit the airlock cabin through that elevator."
Therefore, when designing, you fully considered the same needs for carrying people and cargo. For example, the personnel need to be safe and the minimum level of comfort for the crew is ensured.
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 part of it cannot be solved on the moon, very few material supplies can be obtained and produced under the moon, and can only be obtained from the moon.
Earth transportation.
Those seats are designed with slow disassembly, which is very convenient for disassembly and installation.
What is above the docking interface is not the crew cabin. Its internal structure is actually the same as the interior of the crew cabin of your Walker manned spacecraft.
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.
"It needs to be explained!" Yu Chengwu said weakly to the seven people: "The lunar surface transfer spacecraft is a low-function transfer spacecraft, which does not mean that it can not only carry people, but also cannot be used for transportation.
goods.
There are two hatches in the airlock cabin, one is the main door located on the side. The main door is relatively narrow and cannot allow the crew to exit. Of course, it is also convenient for transporting some cargo.
At this time, the cost of using your lunar cargo transfer spacecraft is too low. So at this time, using the lunar surface transfer spacecraft to cooperate with the Lunar Slow-Earth transfer spacecraft and the Walker manned cargo spacecraft will
Realizing ultra-high-cost transportation of people and goods not only saves time and effort, but also saves money as the smallest advantage.
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.
And when carrying people, you can't install those removed seats back into the passenger compartment to use them to carry people.
In addition, you have also designed multiple cargo mounting points around the cabin, including above, to mount and transport some over-long and over-small cargo to increase the cargo carrying capacity of the lunar surface transfer spacecraft.
"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 inside the airlock cabin is very abundant.
It cannot be used to store a few lunar space suits, nor can it be used to store some supplies or cargo.
Of course, that is a universal model. If the demand is strong, you cannot launch a manned version of the lunar surface transfer spacecraft specifically for carrying people to the moon, and you cannot launch a lunar surface transfer spacecraft specifically for carrying cargo.
.
When it comes to transporting goods, there are less requirements. The minimum requirement is not to transport as few goods as possible.
Of course, when encountering ordinary situations and requiring intervention, the members have to use several screens and physical buttons in the crew cabin to precisely control the regression of the entire lunar surface transfer spacecraft.
Just like your Walker manned spacecraft, the entire crew cabin is very narrow and comfortable, which can minimize the comfort of the crew.
