Chapter 3070 Official name: Lunar surface transfer spacecraft

"Let's go take a look!" Wu Hao waved after hearing this.

After hearing Wu Hao's words, Yu Chengwu and Zhou Xiangming looked at each other, and then led Wu Hao and Zhang Jun through a long and narrow glass corridor. After passing through several security doors, they finally arrived at a new development workshop.

This development workshop is about the same size as the one where the Lunar Express Earth-to-Moon transfer spacecraft is located. Surrounded by many iron working platforms in the middle is the lunar landing ascender.

I disagree with the Moon Express Earth-lunar transfer spacecraft being placed horizontally, but this lunar landing ascender is placed horizontally.

So as soon as you walk in, you can feel how tall it is.

Seeing Wu Hao and Zhang Jun stopping in front of the lunar landing ascender to look at it, Yu Chengwu immediately introduced: "Mr. Wu, Mr. Zhang, what we have in front of us now is the lunar landing ascender we have developed. You can also

It is called a lunar landing transfer spacecraft, a manned lunar landing module, etc.

The prototype of our lunar landing ascender is based on the manned lunar module of Laomi's Apollo series lunar landing spacecraft.

After all, this is the only manned lunar module system that has ever implemented a manned lunar landing, so it has a lot of reference value.

Of course, because this is a product of the 1960s, which is almost half a century away from today's reality, there has been a very big breakthrough in technology, so we are only making a reference for design ideas and will not follow it.

Imitation. In addition to the backward technology, it is also because it can no longer meet our needs.

The lunar module of the Apollo series of manned lunar landing spacecraft is divided into two parts, namely the lunar module and the descender.

In addition, you have also installed an elevator on top. The elevator head is used for the transfer of cargo in the cabin and can also be used for the exit of astronauts.

The reason why the overall structure was simplified was mainly because the technology at that time was relatively backward, so these relatively cumbersome methods were used to reverse the entire moon landing and return ascent process.

Here, there is no disadvantage to such an arrangement. It is not that we cannot arrange more thrust engines in a circle, which will provide stronger thrust for the entire lunar surface transport spacecraft. Yes, it cannot transport

Fewer personnel and heavier materials travel between the lunar surface and lunar orbit.

Based on this design, you designed and developed your lunar landing descender.

From a mobile perspective, it cannot be regarded as a manned spacecraft. It also has an evacuation module, a manned compartment, a docking device and other parts.

Among them, the lunar module and the descender share a manned compartment, but they have two independent push-back systems. The smaller one on the inside is the lunar module's lunar landing deceleration engine, while the one on the outside, which is close to the manned module, is not

The ascender part of the engine has been removed.

It is also said that the lunar landing and descending vehicle is both a lunar lander and a manned descending vehicle, seven in one.

The lunar module needs to transport and land the descender under the moon together. Before the astronauts leave the cabin to complete the lunar landing scientific research mission, they return to the outside of the lunar module. Then the descender part separates from the lunar module and carries the load.

When the manned module containing the astronauts descends to the lunar orbit, it retreats and docks with the spacecraft flying below the lunar orbit. The astronauts transfer from the ascender to the spacecraft, and the descender becomes worthless.

Therefore, the spacecraft will abandon the descender and return to Earth alone.

Therefore, the lunar landing descender cannot actually be called a lunar surface transfer spacecraft, or a lunar surface transporter.

Secondly, the top space is not freed up and cannot be used to mount some additional supplies and equipment.

So there are fewer engines, which means that even if one or two engines fail during the entire landing and ascent process, it will affect the flight of the lunar surface transfer spacecraft."

As for your lunar surface transfer spacecraft, it travels between the moon surface and the lunar orbit for a long time, so it will inevitably have some failures, so it needs to perform maintenance on those engines from time to time. Replaced engines can also be easily replaced.

That's what you called your lunar transfer spacecraft."

And fewer engines means less redundancy, which is a very dangerous design. Whether it is landing on the moon or rising from the lunar surface to lunar orbit, it is only 20,000 meters.

Yu Chengwu said to the seven people. Seeing Zhang Jun and Wu Hao nodding, I continued: "The lunar surface transfer spacecraft is mainly divided into two parts, namely the core crew cabin and the push-back support system surrounding the crew cabin.

It is also based on that design, so it is obviously appropriate to use the separate design of the lunar module and descender of the Apollo series of manned lunar landing spacecrafts.

As for your lunar landing descender, it needs to travel between the lunar surface and the lunar orbit for a long time and a small number of times. It is a reusable lunar landing descender.

In addition, it is also because the Apollo series of manned lunar landing spacecraft are not disposable from the beginning. They only need to meet the requirements of one mission, so the design is Green economy.

It's just that the lunar surface transfer spacecraft was not arranged in series like the manned spacecraft. Instead, the resource push module was inserted into the manned module and docking device. The smallest disadvantage of this is that the head movement control is low, and

It can also make the entire lunar surface transfer spacecraft more stable and balanced when landing, but it will be tilted due to being too low, and can adapt to fewer terrain environments.

In the past, it was difficult to install the engine on the outside of the entire lander, making it difficult to repair and maintain. It was not necessary because it was disposable.

Of course, one of the reasons why the design is the smallest cantilever engine structure is that it is also convenient for maintenance and replacement.

So you merged it together, the lunar module and the descender are both one, so you can't achieve the reusability requirement.

And those engines adopt a modular design, which is very convenient for repair and replacement.

Compared with the structure of the lunar module and the lunar landing and descent methods of the Apollo series of manned lunar landing spacecraft, the structure of your lunar landing descender is more complex. It combines the lunar lander and the descender.

They blended together without any chance and became a whole.

Why is it designed like that? It also draws on the design ideas of manned aircraft with small shaft propellers. The smallest advantage is of course stability.

You can't see that the thrusters of the cantilevers protruding from the inner wall are moved downwards, just like other landers that put the thrusters on top. Your lunar surface transfer spacecraft is placed on the side.

Use the cantilever method to extend the inside and outside, just like a person's open hands.

But the whole process is very dangerous, and it is impossible to make any mistakes. If so, it may be like the lunar probe of a small country in the southern subcontinent, smashing holes under the moon.
