Chapter 513: Impact test

A silver dome stands in the darkness, and the arc-shaped dome structure shines light from the inside, lighting up the entire dome.
Although the light is not very obvious, and the thickness of the dome also restricts the penetration of internal light, it still makes this dome like a beacon in the dark night, which can guide the direction of passers-by in the distance to return home.
However, at this moment, a meteor that was far more dazzling than the dome struck the sky.
The friction between the star and the air ignited the air and burned with bright light, like a sun rising in the dark night, illuminating the dark sky.
The meteor dashed across the sky and fell towards the dome, seeming to aim at the dome deliberately and want to smash it.
As the meteor continued to fall, it eventually hit the dome, pierced through the outer insulation, airbag layer and steel structure support of the dome with an unstoppable momentum, and fell into the interior of the dome.
However, when the meteor fell into the dome, everything seemed to be paused and stopped.
"It seems that after the diameter of the meteorite breaks through one meter, the destructive power will be enough to destroy the current dome city." Chen Xin's figure appeared on the dome where the meteorite had penetrated, looking at the place where it was penetrated and around the breach. Chen Xin frowned in the flames.
This is a virtual projection made by him in the holographic image room of the refuge, using virtual images to simulate the possible damage caused by a meteorite hitting the dome.
Chen Xin simulated the damage caused by meteorites of various sizes hitting the dome. From the smallest one centimeter in diameter to the one meter in diameter just now, each meteorite hit the simulated dome directly.
However, through testing, Chen Xin discovered that the damage to the dome itself is not too great by the meteorite.
Even when the one-meter-diameter meteorite hit the dome just now, it did not cause much damage to the dome, but all the EFTE airbags within 50 meters of the impact point were squeezed, creating a diameter. It's about a breach of about five meters.
This is not particularly serious damage to the dome itself, which has a diameter of five kilometers.
Although it is necessary to replace all EFTE airbags centered at the impact point and within a radius of at least 60 meters, and to replace the steel support within a radius of at least 100 meters below, it is still not very serious damage.
However, for the dome city itself, a meteorite with a diameter of one meter can cause damage after the impact is enough to destroy most of the city.
"So there is no problem with my thinking, but the city itself cannot withstand the impact of this series." Chen Xin rationalized his thinking and recorded the test results of the last impact in his experimental logbook.
Chen Xin's purpose of doing this test is mainly to test whether the structural support built inside the EFTE airbag can enhance the defensive performance of the dome.
After testing, Chen Xin came to the conclusion that if the meteorite is not large in size, doing so will indeed help maintain the structure of the dome itself, and will not break a large hole due to the impact.
This is mainly because during the impact, the dome will be squeezed by the impact generated by the impact of the meteorite. The closer the EFTE airbag is to the impact point, the easier it is to squeeze. In this case, if there is a support structure inside, the airbag can undoubtedly be maintained. The approximate shape of the squadron will not collapse due to being squeezed out.
Of course, the support structure also has its limits. As the meteorite increases, the squeezed area becomes larger and larger, and the closer to the impact point, the more serious the damage to the airbag, even the support structure itself Was squeezed to pieces.
However, on the airbag with a certain distance from the impact point, the support structure plays a very good role. Even if the airbag is squeezed, the support structure can still maintain the shape of the airbag without collapsing.
Therefore, this method of erecting support inside the EFTE airbag can indeed enhance the structural strength of the airbag itself, but it does not greatly improve the defense against meteorites.
But this is also normal. After all, it is a meteorite, not something else. The force generated by the impact is enough to penetrate the main armor belt of the battleship. Even if Chen Xin lays a layer of steel on the top of the dome, it should be penetrated or it should be penetrated. .
Chen Xin's original idea was to use the dome as a buffer layer, so that the impact of meteorites on the ground would not be so powerful.
But after testing, he found out that this didn't actually play a big role.
Although the dome does play a certain buffer role, for meteorite impact, when the meteorite can penetrate the dome and hit the ground, the meteorite itself that can greatly reduce the impact will not cause much damage, but will cause a large area. Destroyed meteorites can still cause great damage even if their power is reduced.
What's more, when the power of a meteorite reaches a certain level, it can directly destroy the entire dome city, but the dome itself is just knocked out of a big hole.
According to this test, Chen Xin concluded that it is necessary to strengthen the airbag strength, but it is not as reliable as developing a city-level shield to rely on it to resist meteorite impact.
After clarifying his thoughts, Chen Xin turned off the projection of the holographic image room, restoring it to its original appearance, and was about to leave to rest, but noticed that Qin Lan was standing there at the door.
"What's the matter, Alan?" Chen Xin looked at Qin Lan standing at the door with her arms folded, and asked her, "Is something wrong with me?"
"I can't find you if I'm okay?" Qin Lan responded to Chen Xin, walked towards him, and asked him: "I saw you are experimenting. Is that a dome city to be built?"
"Yes, what's wrong with UU reading www.uukanshu.com?" Chen Xin was a little surprised why Qin Lan asked this question.
"Then when the city is built, can we move in?" Qin Lan looked at Chen Xin expectantly, bit her lip before continuing: "I'm thinking about our future. If we have children, it's impossible. Let the children live underground like this, right?"
"Children?" Chen Xin heard Qin Lan say this, and he couldn't help but fall into thinking.
I have to say that Qin Lan raised a very realistic question.
Although the relationship between Chen Xin and Qin Lan and Mo Qingyan is very delicate, after all, all three of them want to have children in the future.
With children, the future parenting of children is an issue that must be considered.
It's just that Chen Xin hasn't considered this point carefully. He thought about it and said to Qin Lan: "Moving to live in the new city, it's not a big problem. But why do you think of your children well?"
"I..." Qin Lan blushed and didn't know how to answer, so she hugged Chen Xin's neck and kissed his lips.
