"In addition, we can also accommodate ten to fifteen people for short-term stay. In other words, we can accommodate twenty to twenty-five members for short-term stay on this space station."

"How can we accommodate so many people?" Everyone obviously didn't believe it when they heard the number Wu Hao said. Let’s not talk about our own space station, let’s just talk about the size of the International Space Station. How many members can it accommodate? You Wu Hao suddenly said that it can accommodate more than 20 people. Is this possible?

Wu Hao smiled and replied: "Absolutely. In fact, such an inflatable inflatable cabin can be used for living."

"We have specially designed a living cabin like this. Inside this cabin, we also use this soft material to inflate and divide it into small living cabins. Each living cabin is two meters long, one meter wide and one meter high. meters, it can accommodate members to rest very comfortably inside.”

Wu Hao led everyone to an internal anatomy model of an inflatable inflatable space capsule and introduced it to everyone.

Inside this huge pumpkin-shaped inflatable space capsule, it is divided into rectangular spaces by a shape similar to the spread of petals. These rectangular spaces are the living and resting cabins introduced by Wu Hao. These living cabins are arranged in relevant order and structural combinations, leaving some relatively spacious passages connecting each living cabin.

I have a question, will such an inflatable space capsule be prone to fire? On the space station, the most taboo and dangerous thing is fire. Once a fire breaks out, it will spread quickly and be difficult to handle. As for members, it is often difficult to escape due to the rapid spread of fire. At this time, an expert raised an issue that everyone was most concerned about and worried about.

This question was very targeted, so after asking the question, everyone immediately looked at Wu Hao, waiting for his answer.

Wu Hao smiled when he heard this, because they had already considered such a problem. Therefore, he was confident and calmly led everyone to an expandable inflatable space capsule polymer composite sample placed nearby and introduced it to everyone.

"This is the polymer composite material that makes up the inflatable inflatable space capsule. Please see, the wall of this space capsule is actually composed of more than a dozen different layers of polymer composite materials, including the outermost protective layer. The internal structural layer and the sponge-like cavities in the middle are filled with special liquid used for automatic repair when the cabin ruptures.

The innermost layer is the antibacterial layer. The main function of this antibacterial layer is to inhibit the growth of bacteria in the cabin, thereby ensuring a hygienic environment within the entire space capsule.

As for the fire prevention issue that everyone is most worried about, this was taken into consideration at the beginning of our design. The polymer composite walls that make up this inflatable inflatable space capsule have strong fire resistance, unless they are continuously burned at thousands of degrees. Burn, otherwise it will be difficult to burn.

Moreover, in addition to some cables throughout the entire wall of the inflatable inflatable space capsule, there are also numerous micro-sensors scattered throughout. These sensors monitor the status of the entire inflatable inflatable space capsule at all times. Once a problem occurs, such as where it is damaged, where the temperature is abnormal, etc., it will be quickly fed back to the cabin system. "

With that said, Wu Hao motioned to the staff who were ready. The two staff members understood and immediately began to demonstrate to everyone.

One person held a long strip of polymer composite material, and the other person lit a small flame spray gun and began to spray and burn the polymer composite material. The temperature of this flame spray gun is very high, and its maximum external temperature can reach thousands of degrees.

However, under the continuous burning of the flame spray gun, the polymer composite material showed no signs of burning. Immediately, the staff member took a flame spray gun and burned the two for a long time. The polymer composite material still did not burn, but slowly turned black.

It probably burned for a minute or two before the staff member stopped and turned off the flame. Another staff member holding a polymer composite material put the polymer composite material in his hand into a tray, and then walked to the crowd to show it to everyone.

Wu Hao picked up a tweezer from the tray, then poked the burnt end of the polymer composite material placed in the tray, and then some black powdery lumps fell off.

While demonstrating, Wu Hao introduced to the crowd: "This kind of polymer composite material will slowly burn, carbonize and decompose only when it is burned at high temperature for a long time. Once it is removed from the high temperature, it will not burn by itself. .

The reason for this is to comply with relevant international space conventions and prevent the spacecraft from being fully burned when returning to the atmosphere, causing a large amount of debris to fall to the ground, causing pollution and damage. "

After hearing Wu Hao's explanation, these experts looked at the polymer composite materials in the tray, and some even turned over them. However, when some experts were about to pick up and even some people wanted to get contaminated with the burned black powder, they were stopped by the staff.

Seeing the expert's embarrassed look, Wu Hao smiled and explained: "Sorry, this polymer composite material is still in the confidentiality process, and all these related experimental materials cannot be taken out."

After hearing his explanation, the other experts nodded in understanding, but this expert blushed, but still didn't say anything.

In fact, everyone knew what he wanted to do, and Wu Hao was being polite in saying so.

Just when the scene was a little awkward, an expert raised a new question, which solved the problem for the expert.

What should you do if your inflatable inflatable space capsule is damaged and the damage is too severe to repair?

Regarding such a question, Wu Hao smiled, then shook his head and said: "Under normal circumstances, such a problem will not occur.

There are not many factors that can cause such major damage, unless it is hit by larger space debris or small meteorites. But in the face of the impact of ultra-fast space debris and small meteorites, let alone this kind of inflatable inflatable space capsule, even our regular space station would be difficult to stop it. "

After hearing what he said, everyone at the scene nodded. Indeed, no matter what kind of spacecraft it is, so far there is no ability to withstand the impact of these space debris fragments and small meteorites. The methods currently adopted are mainly prediction and early avoidance.

Even so, the International Space Station has been hit by space debris and small meteorites, causing leaks. Even after repairing it several times, the leakage problem still doesn't seem to be stopped.
