Vol 2 Chapter 1186: Inflatable inflatable space capsule

Of course, compared to the "Jianmu-2" modified retractable rocket, what everyone is concerned about is the experimental spacecraft launched this time.
This experimental spacecraft, code-named Oasis, is a space farm experimental warehouse. And, this is still an inflatable inflatable space capsule.
So what is an inflatable inflatable space capsule? This explanation is slightly complicated. To put it simply, it is like a balloon, which is in the retracted state when launched. After launching into space, inflate it, and it can expand and grow like a balloon, thus forming a spacecraft with a larger internal space.
This kind of inflatable inflatable space capsule is currently being studied by countries all over the world, and certain results have also been achieved. The inflatable and inflatable space capsule that Haoyu Technology will launch this time is a new and improved new generation technology product on this basis.
It sounds like this kind of inflatable inflatable space capsule is very simple, you just need to make a better material, make it into a balloon, and then send it to space to blow it up.
But in fact, it is not that simple. First of all, all space capsules must consider one issue, that is, safety.
The environment in space is more complicated. As far as the International Space Station is concerned, it will experience 16 sunrises and sunsets every day (24 hours). That is to say, during these sixteen alternate days and nights, it bears a temperature difference of nearly three hundred degrees between plus and minus. Under the sun during the day, it has to withstand a high temperature of more than 100 degrees and many harmful sun rays. Without sunlight, it will withstand extremely low temperatures of more than 200 degrees below zero.
This repeated alternation of high temperature and low temperature will be a severe test for any material. First of all, we must ensure that this material can withstand this repeated alternation of high and low temperatures. Secondly, it is the service life. This repeated alternation of high temperature and low temperature will increase the fatigue of any material, thereby accelerating the aging of the material and greatly reducing the service life.
In addition, this material must be able to withstand all kinds of harmful cosmic rays. Our earth is under the protection of the magnetic field and atmosphere, so it avoids the invasion of various cosmic rays, so that we humans and life on the earth can survive.
And in the universe, without the barrier of the atmosphere, the earth's magnetic field is weakened, or even there is no magnetic field, then it is necessary to rely solely on aircraft to block these harmful rays.
Of course, there is still a big danger in the universe, that is, unknowable space debris. These fragments are very small, maybe a few centimeters, a few millimeters, and it is impossible to monitor and predict.
What's more, there are some space meteorite fragments. These are more difficult to monitor and forecast. We must know that our planet is attacked by space meteorites every day. Will be enclosed on the ground, which also prevents us humans from being attacked by space meteorites.
In space, these space debris and meteorites at a speed of six or seven kilometers per second have become deadly killers of spacecraft and satellites. Although this probability is very small, it is not impossible. According to the relevant log technology of the International Space Station, it has been hit by small space debris and small meteorites many times during the years of service. Fortunately, it did not cause much damage.
So for this kind of inflatable inflatable space capsule, it naturally gives people an illusion. I think it is as fragile as a balloon, and if you touch it a little, it may explode. Even if it doesn't explode, it will collapse like a balloon or a ball.
Moreover, the materials used in the spacecraft space station are metal and composite materials, giving people the first impression that they are relatively strong. And Wu Hao's inflatable and inflatable space capsule gives people the first feeling that it is fragile, which is not very reliable.
But in fact, this kind of inflatable inflatable space capsule also uses polymer composite materials. This material is also mostly used in spacecraft, space stations and spaceships. The inflatable and inflatable experimental capsule used by Wu Hao and the others is a self-developed polymer composite material. After repeated tests in a simulated environment, this material has reached a very satisfactory result.
For example, generally this kind of material is prone to material aging, hardening, and loss of toughness during a long time of alternating hot and cold temperatures. This material does not. It can maintain thermal properties for a long time in such an environment of alternating cold and heat, and has excellent aging resistance.
In addition, their self-developed new polymer composite material is also very strong. Because of its high strength, it has strong resistance to pull and impact.
However, no matter how strong it is, it is difficult to withstand the impact of those space debris at six or seven kilometers or even ten kilometers per second. Not to mention this kind of polymer composite material, even the hardest metal chromium and titanium in the world can't bear it.
Therefore, human spacecraft did not expect to rely on materials to prevent these debris from hitting, but established an accurate debris detection and prediction mechanism. UU Reading www.uukanshu.com monitors the state of debris in space in real time, thereby adjusting the orbit of the spacecraft and avoiding debris.
Secondly, this is to have good self-healing ability and repair ability. In other words, after being hit by these debris, the spacecraft can repair itself in time, or quickly repair it. So as to avoid the deterioration of the situation, threatening the safety of the spacecraft, and even the safety of the astronauts inside the spacecraft.
In the imagination of scientists, future spacecraft will have a certain degree of self-healing ability, that is, self-healing ability. Put a special liquid into the interlayer of the spacecraft shell. If the shell breaks, these special liquids will quickly gather at the damaged part and solidify, thereby blocking the leaked part of the impact damage.
The technology research and development team for this inflatable inflatable space capsule project used this technology on this inflatable inflatable space capsule.
A special liquid is injected into the polymer composite interlayer of the inflatable inflatable space capsule. When the inflatable inflatable space capsule leaks, this special liquid will block the leak in the shortest time. Prevent pressure inside the spacecraft and outflow of air in the cabin.
In addition, the inflatable and inflatable shell of the inflatable inflatable space capsule is made of overlapping materials, which further enhances the strength and strength of the inflatable inflatable space capsule, and its comprehensive performance has even exceeded that of traditional spacecraft. The metal material shell.
In addition, the shell of the inflatable inflatable space capsule is still composed of many horizontally and vertically connected inflatable grids compressed by polymer composite materials. This kind of air grids can be folded together to save space when they are not inflated. It unfolds automatically and has strong support.
