Military Technology

Attention everyone, I am number zero, I have two hours to prepare!

As the announcement in the hall sounded, everyone's hearts moved.

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

Different from traditional spacecraft and Dragon spacecraft, Walker 4 has only one entrance and exit, which is the docking port and exit hatch at the top. There are two Dragon spacecrafts, and there will also be an entrance on its side specifically for astronauts to enter. As for 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 setting up this special horizontal entrance is that 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 module to the return module is too high. , very inconvenient and dangerous to enter.

That's why engineering designers opened such an entrance on the side of the orbital module to allow astronauts to enter. Of course, this entrance will occasionally be used as an exit hatch, and the entire orbital module of the spacecraft can be turned into a space airlock for astronauts' exit activities. Our first out-of-warehouse experiment was like this.

As for why the Dragon spacecraft has such a horizontal entrance on the manned cabin, it may also be for convenience.

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

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

In fact, like the Dragon spacecraft, the Walker series spacecraft does not require a fairing. Therefore, in order to protect the safety of the docking interface, the relevant structures are not affected by the friction and burning of high-altitude high-speed airflow. Therefore, the Walker series spacecraft also has a fairing outside the top docking interface. The protective "cap" is actually a cover that covers the entire docking interface.

When the astronauts enter the manned return capsule, the cover will open to reveal the docking port inside. The docking port will also be opened by technicians, and a ladder will be placed to facilitate personnel entry.

The height of the entire rocket docking interface is about one meter higher than the rotating platform, so the staff placed a wooden step next to it to make it easier for people to get up.

At this moment, several staff members wearing dark gray T-shirts and black masks were already standing there, waiting.

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

Although this is not the first time that everyone has seen the scene inside Walker 4, this time because there are people as reference objects, everyone has a deeper understanding of the space inside the spacecraft.

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

First of all, the space inside the spacecraft is very large. Compared with the small space of traditional spacecraft, which requires astronauts to huddle together, the internal space of the new generation of manned spacecraft is very large.

Wu Hao's Walker series is very similar, with a large internal space. After all, this spacecraft can accommodate up to six to eight astronauts, which shows how much space it has.

At this time, there was only one chair placed in the huge space inside the spacecraft, which seemed a bit empty, and there were some supplies and facilities behind it. The most surprising thing is that in the return capsule of such a spacecraft, a simple toilet is 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 astronauts' diet was strictly controlled a week or even earlier from the launcher, so as to reduce and eliminate the astronauts' excrement as much as possible.

Nowadays, diapers, the essential household supplies for mothers and infants that we are all familiar with, were actually first used by astronauts. Because there were no toilets in space at that time, astronauts could only rely on diapers to solve personal convenience problems.

It's the same now. For example, in some outbound activities, astronauts have to stay in space for seven or eight hours. During these seven or eight hours, there will inevitably be internal emergencies. How to solve them cannot be solved by returning to the space station and then coming out to continue space walking. This is obviously unrealistic.

Therefore, astronauts will wear adult diapers when performing outbound missions to solve the astronauts' urgent needs.

In addition, there are also some traditional manned spacecraft that perform the same tasks of transporting personnel to the space station. Whether it is launched from the ground into 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 unexpected launches, astronauts are not allowed to take off their spacesuits in the cabin, let alone use the toilet. Therefore, astronauts also need to wear diapers during this process 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 and landing phase of the spacecraft, so he also needs to wear diapers, just in case.

Of course, after the spacecraft actually enters space orbit, the spacecraft flies normally and the cabin environment is normal, Yuan Zifeng can take off the spacesuit in the cabin and put on ordinary clothes, and at this time he can use this simple toilet.

With the help of the staff, Yuan Zifeng began 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 with some white and blue lights decorating 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 its ascent and landing, and can protect the astronauts from severe impacts. harm.

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