A silver dome stands in the darkness, and the arc-shaped dome structure emits light from within, 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 the dome like a lighthouse in the dark, guiding passers-by from afar in the direction of home.
However, at this moment, a meteor that was far more dazzling than the dome streaked across the sky.
The friction between the stars and the air ignited the air, burning brightly, like a sun rising in the dark night, illuminating the dark sky.
The meteor streaked across the sky and fell in the direction of the dome, as if it was deliberately aiming at the dome and trying to destroy it.
As the meteor continued to fall, it finally hit the dome. With its irresistible momentum, it penetrated the outer insulation material, air bag layer and steel structure support of the dome, 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 exceeds 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 was penetrated, looking at the punctured place and around the breach Chen Xin frowned as the flames ignited.
This is a virtual projection he made in the holographic imaging room of the shelter, 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 with a diameter of one centimeter to the one with a diameter of one meter just now, meteorites hit the simulated dome directly.
However, through testing, Chen Xin discovered that the damage caused by the meteorite to the dome itself was not too great.
Even when the meteorite with a diameter of one meter hit the dome just now, it did not cause much damage to the dome. It only caused all the EFTE airbags within a radius of fifty meters around the impact point to be exploded, causing a diameter of It was only a gap of about five meters.
This is not particularly serious damage to the dome itself, which has a diameter of five kilometers.
Although all EFTE airbags within a radius of at least 60 meters centered on the impact point later need to be replaced, and the steel structure supports below within a radius of at least 100 meters need to be replaced, the damage is still not very serious.
However, for the dome city itself, the damage caused by a meteorite with a diameter of one meter after impact is enough to destroy most of the city.
"So there is nothing wrong with my idea, but the city itself cannot withstand this series of impacts." Chen Xin rationalized his thoughts and recorded the test results of the last impact in his experimental notebook.
Chen Xin's purpose of doing this test was mainly to test whether building structural supports inside the EFTE airbag could enhance the dome's defensive performance.
After testing, Chen Xin came to the conclusion that if the meteorite is not large, then doing so will indeed help maintain the structure of the dome itself and prevent a large hole from being broken by the impact.
This is mainly because during the impact, the dome will be squeezed by the impact of the meteorite impact. The closer the EFTE airbag is to the impact point, the easier it is to be exploded. Under such circumstances, if there is a support structure inside, the airbag can undoubtedly be maintained. Its general shape will prevent it from collapsing due to being squeezed.
Of course, the support structure also has its limits. As the meteorite grows larger, the range of compression becomes wider and wider. The closer to the impact point, the more serious the damage to the airbag will be. Even the support structure itself will be damaged. Crushed.
However, on the airbag that is 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 supports 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 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 plate on the dome, it will still be penetrated. .
Chen Xin's original idea was to use the dome as a buffer layer to prevent meteorites from hitting the ground with such force.
But after testing, he discovered that it actually didn't have much effect.
Although the dome does play a certain buffering role, for meteorite impacts, when the meteorite can penetrate the dome and hit the ground, the meteorite itself, which can be greatly reduced in impact, will not cause much damage, but will cause large-scale damage. Even if the power of the destroyed meteorite is reduced, it can still cause great damage.
What's more, when the power of the meteorite reaches a certain level, it can directly destroy the entire dome city, but the dome itself will only be hit with a big hole.
Based on this test, Chen Xin concluded that it is necessary to strengthen the airbag, but expecting it to withstand meteorite impacts is not as reliable as developing a city-level shield.
After clarifying his thoughts, Chen Xin turned off the projection in the holographic imaging room and restored the place to its original appearance. He was about to leave to rest when he noticed Qin Lan standing there at the door.
"What's wrong, A Lan?" Chen Xin looked at Qin Lan standing at the door with her arms folded, and asked her, "Do you have anything to do with me?"
"Can't I come to you if I have nothing to do?" Qin Lan replied to Chen Xin, walked towards him, and asked him: "I saw you were doing experiments. Is that the new dome city to be built?"
"Yes, what's wrong?" Chen Xin was a little surprised why Qin Lan asked this question.
"Then when the city is built, can we move there?" Qin Lan looked at Chen Xin expectantly, bit her lip before continuing: "I am thinking about our future. If we have children, it is impossible Are you going to let your children live underground like this?"
"Child?" When Chen Xin heard Qin Lan say this, 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, Qin Lan and Mo Qingyan is very delicate, after all, the three of them want to have children in the future.
And after you have children, the issue of raising your children in the future is an issue that must be considered.
However, Chen Xin had not thought about this in detail. He thought about it and said to Qin Lan: "Moving to the new city is not a big problem. But why do you think about your children so much?"
"I..." Qin Lan blushed and didn't know how to answer, so she simply hugged Chen Xin's neck and kissed his lips.
