Military Technology

Attention everyone, I am No. 0, ready in two hours!

As the hall broadcast sounded, everyone's hearts also moved.

Yuan Zifeng, who had been resting at the launch tower, finally got up and began to enter the manned return capsule of the Walker 4 spacecraft with the help of the technical staff of Haoyu Aerospace.

Different from traditional spacecraft and Dragon spacecraft, Walker 4 has only one entry and exit port, which is the docking port and exit hatch at the top. The Dragon spacecraft has two, and there will also be an entrance on its side for astronauts to enter. As for the traditional manned spacecraft, because it is wrapped in the fairing, it usually has a special entrance, but it is located on the orbital module above the spacecraft.

The reason for the establishment of this special horizontal entrance is because the entire spacecraft is wrapped in the fairing, so it is too difficult to enter from the top, and the height from the docking port at the top of the orbital cabin to the return cabin is too high. , access is very inconvenient and dangerous.

Therefore, the engineering designers will open such an entrance on the side of the orbital module to satisfy the entry of astronauts. Of course, this entry port will also be used as an exit hatch occasionally, and the orbital compartment of the entire spacecraft can be turned into a space airlock for astronauts to exit the warehouse. Our first out-of-stock experiment back then was like this.

As for why the Dragon spacecraft set up such a horizontal entry port on the manned cabin, it may also be for convenience.

In fact, in the original design of the Walker spacecraft, there will also be such a warehouse. However, opening such a lateral entrance on the main manned return capsule will inevitably damage the integrity of the entire spacecraft's manned return capsule and affect the structure.

In particular, this is a reusable manned spacecraft, and the structural safety is even more important. Therefore, in the subsequent modification of the demonstration, the technical experts canceled this horizontal warehouse entrance and directly changed it to the interface from the top. Enter.

In fact, like the Dragon spacecraft, the Walker series ships do not need a fairing, so in order to protect the safety of the docking port, the related structures are not affected by the friction and burning of high-speed airflow at high altitudes, so the Walker series spacecraft also have a top docking port outside the port. The protective "cap" is actually a cover that covers the entire docking port inside.

When the astronaut enters the manned return cabin, the cover will be opened to reveal the docking port inside, and the docking port will also be opened by the technicians, and a ladder will be placed to fly for the convenience of personnel to enter.

The height of the entire rocket docking port is about one meter higher than the rotary platform, so the staff put a wooden step next to it to facilitate the personnel to go up.

At this moment, several staff members wearing dark gray t-shirts and black masks are already standing there waiting in battle.

Yuan Zifeng stepped onto the revolving platform, waved to the staff, greeted him, and then said hello to the live camera held by the on-site staff, then walked to the wooden steps, and then two technicians began to assist. He, went down from the docking port of the spacecraft and entered the manned return capsule.

Although it is not the first time that you have seen the scene in Walker 4, but this time because of people as a reference, everyone has a deeper understanding of the space inside this spacecraft.

At this moment, through the live broadcast equipment of the injured staff and the pictures captured by the surveillance cameras in the spacecraft, it is the first time that everyone can really see the environment inside so clearly and intuitively.

First of all, the space inside the spacecraft is very large. Compared with the narrow space of traditional spacecraft, the astronauts need to be huddled together. The interior space of the new generation of manned spacecraft is very large.

Wu Hao and their Walker series are very similar, with a lot of interior space. After all, this spacecraft can accommodate up to six to eight astronauts, which shows how much space it has.

At this time, only one chair was placed in the interior space of the huge spaceship, which seemed a bit empty, and some supplies and facilities were placed in the back. The most surprising thing is that in the return cabin of such a spacecraft, a simple toilet is also prepared for the astronauts, which is convenient for the astronauts to use in the air.

You must know that in the initial astronaut space mission, in order to solve this problem, the astronaut's diet was strictly controlled from the launcher a week or even earlier, so as to reduce the elimination of the astronaut's excrement as much as possible.

Today, diapers, a must-have product for mothers and babies in the family that we are all familiar with, were actually first used in astronauts. Because there were no toilets in space at that time, astronauts could only rely on diapers for personal convenience.

The same is true now. For example, for some out-of-warehouse activities, astronauts have to stay in space for seven or eight hours. In these seven or eight hours, it is inevitable that there will be internal emergencies. How to solve it, you can't go back to the space station to solve it, and then come out to continue the spacewalk, which is obviously unrealistic.

Therefore, astronauts will wear adult diapers when performing the mission out of the warehouse, so as to solve the urgent needs of the astronauts.

In addition, the same is true for the space station personnel transportation tasks performed by some traditional manned spacecraft. Whether it is launched from the ground to the space station or returned to the ground from space, it takes seven or eight hours, which is still the fastest.

During this process, in order to avoid accidental launch, astronauts are not allowed to take off the space suit in the cabin, let alone go to the toilet. Therefore, in this process, astronauts also need to wear diapers to avoid internal emergencies.

Including, Yuan Zifeng is the same at this moment. Although there is a simple toilet in the manned return capsule, he cannot take off the space suit in the capsule during the entire launch phase of the spacecraft and during the landing phase, so he also needs to wear diapers, just in case.

Of course~www.readwn.com~ After the spacecraft really enters the space orbit, the spacecraft is flying normally and the cabin environment is normal, Yuan Zifeng can take off the space suit in the cabin and put on ordinary clothes, and at this time, he can use it. This simple toilet.

With the help of the staff, Yuan Zifeng started to sit on the seat in the middle of the cabin. This seat looks a bit simple, but the design is more sci-fi, especially some white and blue lights are decorated in it, which is very futuristic.

However, the technology on this chair is not low at all. It can greatly absorb the vibrations generated by the spacecraft during the ascent and during the landing, and can protect the astronauts from harm.

The staff connected the cables and pipes to the space suit on Yuan Zifeng's body, and several blue and white indicator bars on the space suit also lit up, especially the transparent display screen above the helmet mask, which was more sci-fi.
