I can upgrade the shelter-Chapter 615 - 513 Impact Experiment Test

A silver dome stands in the darkness, and the arc-shaped dome structure emits light from within, illuminating the entire dome.

Although the brightness is not very obvious, the thickness of the dome restricts the light from coming through, yet it still makes this dome like a lighthouse in the night, guiding travelers from afar toward home.

Right at this moment, a meteor far more dazzling than the dome streaked across the sky.

The friction between the celestial body and the air ignited the air, creating a brilliant glow, like a sun rising in the night, lighting up the dark sky.

The meteor streaked across the sky, falling toward the direction of the dome, seemingly aiming deliberately at the dome intending to smash it.

As the meteor continued to fall, it finally hit the dome with irresistible force, piercing through the dome's outer insulating material, the airbag layer, and steel structural support, falling into the interior of the dome.

Yet, when the meteor fell inside the dome, everything seemed to pause and came to a halt.

"Looks like the destructive power is enough to destroy the current Dome City once the meteorite diameter exceeds one meter," Chen Xin's figure appeared at the spot on the dome where the meteorite had pierced, looking at the breach and the flames burning around it, Chen Xin frowned.

This was a virtual projection created in the holographic imaging room in the shelter, simulating the potential damage caused by a meteorite striking the dome.

Chen Xin simulated the damage caused by meteorites of various sizes striking the dome, from as small as a diameter of one centimeter to the most recent one-meter diameter meteorite, each meteorite hit the simulated dome directly.

However, through testing, Chen Xin found that actually, meteorite damage to the dome itself wasn't too severe.

Even when the one-meter diameter meteorite hit the dome, it didn't cause much damage to the dome, merely the EFTE airbags within a fifty-meter radius of the impact point were compressed and exploded, creating roughly a five-meter diameter breach.

This wasn't particularly severe damage to the dome itself, which reached five kilometers in diameter.

Although afterward, it would be necessary to replace all EFTE airbags within at least a sixty-meter radius centered at the impact point, and replace steel structural supports underneath at least a one hundred-meter radius, it still wasn't considered serious damage.

However, for Dome City itself, a one-meter diameter meteorite hit causing damage was sufficient to destroy most of the city.

"So my thinking was not wrong, but the city itself can't withstand impacts of this magnitude," Chen Xin sorted his thoughts and recorded the results of the last impact test in his experiment notebook.

The main purpose of Chen Xin's test was to evaluate whether building structural support within the EFTE airbags could enhance the dome's defensive capacity as he previously thought.

And after the test, Chen Xin concluded that if the meteorite volume wasn't large, then indeed, this approach could help maintain the dome's structure, preventing large holes due to impacts.

This is mainly because during the impact, the dome suffers compressive stress from the meteorite. The closer it is to the impact point, the easier the EFTE airbags are compressed and exploded. Under such circumstances, internal structural support undoubtedly helps maintain the airbag's general shape, preventing collapse due to compression.

Of course, the structural support also has limits; as the meteorite increases in size, the range affected by compression becomes larger, and closer to the impact point, the airbags suffer more severe damage, even crushing the structural support itself.

However, on the airbags at a certain distance from the impact point, the structural support is very effective. Even if the airbags explode, the structural support can still maintain the airbag's shape to prevent collapse.

Therefore, setting up support within the EFTE airbags can indeed strengthen the airbags' structural integrity, but it does not substantially improve meteorite defense capability.

But this is reasonable, after all, it is a meteorite, not something else. The force generated by the impact is enough to penetrate a battleship's main armor belt, even if Chen Xin layers steel plates on the dome, it will still be penetrated.

Chen Xin initially envisioned the dome as a buffer layer, reducing the meteorite's impact power on the ground.

But after testing, he realized this doesn't serve the intended purpose.

Although the dome indeed has a certain buffering effect, in terms of meteorite impact, when a meteorite can penetrate the dome and strike the ground, a meteorite having its impact force significantly reduced wouldn't cause major damage, whereas a meteorite causing widespread damage will still cause enormous destruction despite the reduced power.

More so, when the meteorite's force reaches a certain level, it can directly destroy the entire Dome City, while the dome itself is just struck open with a big hole.

Based on this test, Chen Xin concluded that strengthening airbag integrity is necessary, but relying on them to resist meteorite impacts is less reliable than developing city-level shields.

Clarifying his thoughts, Chen Xin turned off the holographic imaging room's projection, restoring the place to its original appearance, ready to leave for a rest but noticed Qin Lan standing at the doorway.

"What's up, Lan?" Chen Xin asked Qin Lan as she stood at the doorway, her arms crossed: "Looking for me for something?"

"Can't I find you if there's nothing?" Qin Lan replied to Chen Xin, walking over, and asked him: "I saw you doing an experiment, that's for the new Dome City, right?"

"Yes, what about it?" Chen Xin was rather puzzled why Qin Lan asked about this.

"When the city is built, can we move there?" Qin Lan looked at Chen Xin expectantly, biting her lip before continuing: "I'm thinking about our future; if we have children, we can't let them keep living underground, right?"

"Children?" Upon hearing Qin Lan, Chen Xin also fell into contemplation.

Indeed, Qin Lan raised a very realistic issue.

Though the relationship between Chen Xin, Qin Lan, and Mo Qingyan was delicate, ultimately, all three wanted children in the future.

And once they have children, raising them would be a matter that must be considered.

It's just that regarding this, Chen Xin hasn't thought it through yet; he pondered and said to Qin Lan: "Moving to live in the new city shouldn't be a problem. But why are you suddenly thinking about children?"

"I…," Qin Lan blushed, unsure how to answer, so she decisively hugged Chen Xin's neck and kissed his lips.
