Voyage of the Stars

Taking into account future maintenance, the residential cabin adopts modular suspension type. Each suspended module is equivalent to a 60-meter-high building.

Assuming that each floor is 2.8 meters, one residential cabin suspension module has 21 floors, and with two households on one floor, one residential cabin suspension module can have 42 suites.

If there are three people in each apartment, then a hanging residential module can accommodate 126 people. With more than 88,000 people, approximately 705 residential cabin suspension modules are needed.

Of course, it cannot be simply calculated as three people per suite. After all, there are also rooms for living alone or for working. However, the difference is not big. A maximum of 900 hanging modules is enough.

In this design plan, the bottom area of ​​each suspension module of the residential cabin is about 180 square meters. Each floor can be divided into two rooms of 90 square meters, or it can also be used as a large room for other purposes such as offices. class purpose.

If so, the height of the cylinder must be at least seventy meters.

In the design plan, Yue Yuan saw that the length of the spacecraft, that is, the height of the cylinder, reached 980 meters.

There is such a big difference!

After listening to the introduction carefully, Yue Yuan realized that redundancy, nuclear reactors and various functional facilities had been taken into consideration.

For example, ecological recycling systems, plantations, laboratories, various material storage warehouses, etc.

Indeed, a residential spacecraft cannot only consider the living space, but also various other supporting facilities and storage warehouses for machinery and equipment that humans may pack away in the future.

Yu Nanfeng continued to introduce.

Perhaps he felt that just talking about it was not realistic enough, so he also imported the design data into the computer and demonstrated the 3D drawing of the spacecraft to Yue Yuan in person.

Graphics definitely sound more real than just hearing them.

Yue Yuan looked at the computer screen and saw a large cylinder with various numerical values ​​floating inside. It is not difficult to see from the marked values ​​that this is a barrel-shaped spacecraft with a radius of 550 meters and a length of 980 meters.

Viewed from the bottom, five thick arms extend from the central axis of the spacecraft to the outer wall. Each arm pulls a building base. The building base is inlaid with sixty-meter-high building suspension modules. It looks like this. It's like a bee pupa embedded in a honeycomb.

There are five force arms and one disk. The 100-meter-high cylinder is made up of ten such disks. Each disk has an independent power system to drive its rotation.

These power systems are actually a super-large motor. Through the control system, ten super-large motors can drive ten large turntables to perform synchronous rotation, or they can also form a super-large linkage motor. Together, these ten can be linked to each other at any time. Powered by a large turntable.

The nuclear reactor for energy supply is placed in the center of the shaft.

The core nuclear reactor is a very large facility, so the central axis that houses it is designed as an Optimus Pillar with a diameter of more than two hundred meters.

The main thruster is attached to the outer wall of the rotating shaft, and the auxiliary thrusters are distributed on each moment arm. As for the vector steering thruster, it is installed on the outer edge of the upper and lower bottom surfaces of the cylinder.

Looking at the detailed design plan, Yue Yuan nodded and said happily: "Just use this plan. As for the multi-ship plan, don't throw it away. Gao Kun, you are responsible for changing it into a battleship design. I will ask Pi Te to arrange the relevant departments later. Cooperate and strive to start construction of the spacecraft project within this year."

"No problem, but if it is designed as a battleship, I need the cooperation of the headquarters!" Gao Kun responded.

"Of course." Yue Yuan said simply.

After all, the warship is for the headquarters, and the headquarters must be involved. Although they don't understand the design, they can still give opinions on usage habits and the location of the turrets.

"President Yue, I have a question." Seeing Yue Yuan stand up and leave, Yu Nanfeng spoke quickly.

"Speak." Yue Yuan paused.

Yu Nanfeng hesitated for a moment and reminded: "Even if we build a spaceship, we can't leave Callisto immediately."

"I know, but we can't do nothing, right?" Yue Yuan looked back and sighed.

At that time, Gander had already said about the current situation in the starry sky. Supernova remnants were full of interstellar dust. The spacecraft in the inertial navigation stage would definitely be affected by the dust and slow down. How could he not know?

If we just do nothing, mankind is likely to fall into a negative state with no hope. Therefore, even if we now know that it is difficult to achieve interstellar navigation using nuclear fission propulsion, we have to do it.

Only in this way will people trapped in Callisto see hope of life and have the courage to run forward.

Moreover, it is not completely hopeless, as long as a breakthrough in controllable nuclear fusion is achieved during the construction of the spacecraft. This is possible. Although Callisto's technology has regressed compared to the previous Earth, it is not very big. In the field of controllable nuclear fusion, it has only been around for more than ten years, and it is fully capable of catching up.

It just so happens that the construction of the spaceship also takes a long time.

According to estimates from the Engineering Department, such a large spacecraft project will take at least twenty years to build. Unless the technology takes off again during this period, it will only take a lot longer.

After all, such a large ship was built from scratch and needs to be equipped with various facilities and almost 100,000 hibernation cabins.

In fact, there were originally some warships in the orbit of Callisto, but unfortunately they were all destroyed in the catastrophe.

In short, start the project first. If there is a breakthrough in nuclear fusion technology by then, then the core nuclear fission reactor will be replaced with a fusion reactor, and the same will be true for the thruster.

If there is really no other way, we can only wait until the dust cloud in the supernova remnant is thin enough for interstellar navigation.

"I understand. If that's the case, then this plan needs to be adjusted. The power system installation space must be reserved, and the installation will not be carried out until the spacecraft is in the final stage of construction." Yu Nanfeng looked at the simulation diagram on the screen and said, He asked Yue Yuan what he meant by this.

"By the way, do you have any ideas about the battleship design?" Yue Yuan, who was about to walk out of the door after being interrupted by Yu Nanfeng, suddenly changed his mind and turned around to look at Gao Kun.

"We on Callisto have experience in building transport ships. Although the previous space dock has been destroyed, the technology is still there. I think there is no problem. The key is how big to build." Gao Kun replied.

Yue Yuan said without thinking: "It must be bigger than a transport ship, but it can't be too big. If you want to build one as big as a residential spaceship, our resources will definitely not be enough."

In fact, humans are really not suitable for building warships at this time, but without a warship, Yue Yuan always feels uneasy. Even if he knows that he really wants to encounter aliens, it is probably useless.

"I think there's a problem!" At this time, Yu Nanfeng suddenly stood up from the computer and objected: "It's okay to build a battleship, but how do you drive it away?"

How to drive away?

Just follow the residential spacecraft and drive away! you still need to ask?

Just as Yue Yuan was about to say this, he suddenly thought of the key point of Yu Nanfeng's objection.

Yes, how to drive away? !

You can't let a group of people stay on the battleship all the time. You must know that it is a long journey. Interstellar navigation is a length of time that humans need to hibernate to span.

Let a group of people hibernate in a zero-gravity environment for dozens or hundreds of years? That's bound to go wrong.

It’s really difficult!

But sailing naked is too dangerous. Even if there are no aliens scheduled, at least there are ways to deal with other emergencies.

Those who don’t have a few atomic bombs, hydrogen bombs, helium bombs, or neutron bombs in their hands really feel unsure.
