Military Technology

Amidst warm applause, Wu Hao ended his speech.

Judging from everyone's reactions, Wu Hao's speech was effective. At least the smiles on everyone's faces really came from the heart, which cannot be concealed.

After finishing their speech, Wu Hao and the others immediately came to the most eye-catching Walker 4 return capsule in front of them.

As the person in charge here, Zhou Xiangming smiled at Wu Hao and introduced: "After the return capsule was transported here, we immediately opened the warehouse. After taking out the relevant experimental equipment that went into space with the ship, we carried out inspections on the spacecraft. Understand disassembly analysis.

This move is mainly to study the impact of this mission on the entire return capsule equipment. It is also to verify whether the return capsule has the ability to be reused. From the current point of view, the return capsule is in good condition and fully meets the needs of secondary use. It only needs to replace some insulation materials on the surface.

In addition, we also collected a lot of suggestions and opinions from astronauts, and then studied these opinions and suggestions and made corresponding modifications. For example, there is no toilet in our spaceship. This is a very common problem.

It should be said that all two-compartment spaceships do not have toilets. Only traditional spaceships with a three-compartment structure will have a toilet in the orbital module.

The new generation of spaceships in various countries have a two-compartment structure, so basically there are no toilets. Because it’s not really needed at all. The main mission of these spacecrafts is to transport astronauts to and from the space station. Rapid rendezvous and docking only takes six or seven hours, which is not necessary at all.

But if the spacecraft stays in orbit for too long, a toilet will be needed. This time we set up a recommended toilet inside to meet the astronauts’ toileting needs.

This design was naturally praised by astronauts, and it also solved a big trouble for astronauts during space navigation. But the astronauts also gave us many valuable suggestions for modifications regarding the problems encountered during use.

For example, the location of the toilet is somewhat inappropriate. Every time the astronauts go there, it is very inconvenient, and some water droplets will flow out. In the end, the astronauts have to use suction nozzles and paper towels to absorb these water droplets.

In addition, there is no privacy protection in this toilet. Although it cannot be photographed, it still feels a bit indecent. It's okay for one person, but if there are many people and the opposite sex is around, it will definitely be inappropriate. Therefore, the astronauts suggested that in the future, a folding and storage curtain or something should be installed outside the test to cover the shame, so as not to cause embarrassment or anything. "

Wu Hao and the others nodded when they heard this. This seemed to be a small problem, but it was indeed a big matter. After all, if people want to live, eating, drinking, eating, drinking, and sleeping are essential, especially living in the universe and especially in a weightless environment. If this problem is not solved, then it will definitely not work.

So after listening to Zhou Xiangming's introduction, Wu Hao smiled and looked at him and asked, "How did you solve it?"

Hearing his inquiry, Zhou Xiangming smiled and swiped the screen in front of him, brought up a 3D structural diagram of the return capsule and introduced it to everyone.

"Actually, the toilet in the return capsule is generally of little use, which is why it is not included in so many new-generation spacecraft. It is mainly responsible for transporting personnel and materials to the space station.

Using rapid rendezvous and docking technology, as well as rapid return technology, it can basically reach the space station or return to the ground in six or seven hours. This problem can be completely solved by adopting reasonable meal control before the mission, and this is what all countries do.

Of course, there are also situations like what the astronauts said, that is, the spacecraft flies independently in space for too long, and then such a toilet is needed to solve the big problem of the astronauts.

Previously, we installed a toilet on top, which could temporarily relieve people's urgent needs. After listening to the relevant opinions and suggestions from astronauts this time, we conducted research and re-optimized the space utilization pattern inside the spacecraft.

On the left side behind the seat in the spacecraft's manned return cabin, a closed toilet is installed instead of a seat. "

Speaking of which, Zhou Xiangming also showed a schematic diagram of the toilet's location in the return capsule on the screen.

"One good thing is that our spacecraft adopts a modular design, so it is more convenient to remove the seats and install the toilet. We can choose to install seats or install toilets according to mission requirements.

Even if we choose to install a toilet, our spacecraft can still accommodate up to seven astronauts. The carrying capacity is also leading among similar spaceships. "

It looks a bit small. Is it convenient to accommodate an astronaut inside? Zhang Jun looked at the three-dimensional design diagram on the screen and said with some doubts.

absolutely okay. Zhou Xiangming replied with a smile: "Actually, the internal space of this toilet is not small. We made full use of the small space design layout of the spacecraft return cabin. The entire toilet was designed in this half-orange petal style, with the top and bottom , the bottom is large. This also allows the astronauts to sit down inside, and there is a wider space below. On the top, there is a transparent window to see the outside, and the astronauts will not feel claustrophobic when they stay inside.

In addition, we also installed a ventilation and filtering device in this toilet, which can collect the odor generated by the toilet, thereby improving the environment inside the cabin and ensuring the health of the astronauts. "

This is also a big problem reported by astronauts, that is, after using the toilet, this kind of open toilet is easy to produce some odor, and it will exist for a long time. The experience of staying in this kind of space is not necessarily good. It still has its own taste. If there were a few astronauts staying inside, the smell would be unimaginable.

Adding so much weight means that we have to sacrifice a considerable amount of carrying capacity, which only increases a lot of launch costs. Zhang Jun opened his mouth to analyze after listening to Zhou Xiangming's introduction.

Haha, we have also taken this into consideration, so we have also strictly controlled the weight of the toilet and used lightweight materials to ensure strength while also greatly reducing the weight. The entire toilet adds up to the weight of an astronaut.

So it depends on how you choose it during the mission. If you encounter that kind of short-distance transportation mission, you don’t need to equip it at all. If it is a long-term mission, he is still needed. After all, convenience is also a major concern for people, so we can’t turn a blind eye.

Especially in the future, space tourism will be inseparable from it. Remember the website address of this website, www. Biquxu． Com for easy reading next time, or enter " " in Baidu to enter this site
