Doomsday Bunker Upgrade

The re-upgraded research center has changed a lot in appearance. The dome that originally covered the entrance and exit of the main building and Chen Xin's private refuge was enlarged and turned into a city that is slightly smaller than the dome city, but it has A large dome that covers the ecological greenhouses, geothermal energy towers and other supporting facilities around the entire research center.

Not only that, the original weapon test site has also been upgraded, with a larger site and more complete and advanced facilities.

In addition, Chen Xin also purchased two sets of 3D printing equipment for the research center. When the raw materials are complete, these two sets of 3D printing equipment can produce all the active equipment of the Yan Kingdom except land-based aircraft carriers and mobile bases, including small land-based aircraft carriers. row ship.

To this end, Chen Xin also deliberately opened a dock next to the original main building of the research center to park a small land-based ship that was produced.

This small land-propellant is naturally a test product that Chen Xin made to answer the question of the aerospace department.

However, the size of this land traveler is very small. Strictly speaking, it can only be regarded as a miniature land traveler, because it is only half the size of the escort land traveler. Almost big, maybe even smaller.

This land traveler is so small, and naturally the number of personnel it can accommodate is much smaller. Under Chen Xin's repeated streamlining, the land traveler has a load capacity of 12-15 people.

There are only ten cramped cabins on the ship. Of course, compared to the previous spacecraft where astronauts could only sit in the spacecraft and struggle to turn around, it is still a lot more spacious. At least there are two bunks in the cabin. And a desk, the size of a normal room.

Although it is said to be ten cabins, under normal circumstances, two cabins will be used to store materials to increase the activity time of this land-based ship.

The whole ship is powered by nuclear power, and not a nuclear battery, but a tiny nuclear reactor of the kind used in a nuclear-powered train.

This undoubtedly provides a considerable amount of power for this special small land-based ship, so that it can use plasma thrusters to send itself out of the atmosphere and into space.

The reason for using a plasma thruster is mainly because the core component used in the floating of the landline ship is an anti-gravity generator. This device can offset the effect of gravity on the landline ship, but all it can do is and the gravity of the earth cancel each other, and can not produce additional lift.

At a height that is still affected by gravity, the antigravity generator can effectively offset the influence of gravity, allowing the land-based ship to adjust the flight height at will.

However, if the height of the land-based ship continues to increase, the lift provided by the anti-gravity generator will become smaller and smaller until it reaches the ceiling of the land-based ship.

Although this ceiling is in a sense close to breaking through the atmosphere into space, the small landship cannot break through the atmosphere without the help of additional lift.

It is precisely for this reason that Chen Xin installed a high-power plasma thruster for it to provide enough thrust to send the land-based ship completely into space.

If you want to enter space, thrust alone is not enough. After all, space is a vacuum, and land-based ships must ensure that the hull is completely sealed. Otherwise, once the air leaks, the precious air will be lost, and the leak point will become a Extra points of force to let the hull lose control.

This is also one of the reasons why so far, the spacecraft built by humans are not very large, because to ensure the airtightness of the spacecraft, and at the same time to make the outer shell of the spacecraft enough to cope with the harsh environment of outer space, no matter Whether it is material science or structural science, it is an extremely severe test.

Although Chen Xin can use the system upgrade method to upgrade the entire land ship into a spaceship capable of interstellar voyage, but considering that this is a spacecraft to be delivered to the aerospace department, Chen Xin still uses the current Yan Kingdom as much as possible. The technology that is available and can be done to build this landship.

Fortunately, there is now 3D printing technology, which can directly print the shell of the entire ship without creating any gaps. Compared with traditional production and construction technology, it is undoubtedly much better in ensuring the airtightness of the hull.

As for the hull material of this land-based ship, Chen Xin doesn't need to worry about it. The aerospace department has come up with the best material formula they have, which is what was used for spacecraft manufacturing before.

It's just that these ingredients were so expensive even before the disaster that only the top national dishes of Blue Star could afford them. As for the post-apocalyptic days, even the Yan Kingdom, the best country with comprehensive national strength recovery, could afford it. , is not so easy to get out.

Of course, there are no countries with raw material reserves, but these raw materials themselves are scarce resources. In addition to the aerospace sector, other sectors and fields also have great demand.

Not to mention, just to produce a reactor for nuclear-powered locomotives, it also requires the use of a large number of scarce resources to ensure the safety of nuclear reactors.

This is also one of the main reasons why Chen Xin built this land-based ship so small, because there are really not enough raw materials.

With the raw materials granted by the state to the aerospace sector, and some of the materials they have on hand, after Chen Xin tried his best to improve the utilization of materials, he could only build such a large land cruiser.

Of course, even so, the length of this land-based ship is more than fifty meters long, and it really belongs to the category of behemoths in spacecraft.

For such a large ship, in addition to the need to ensure the strength of the hull with a thick enough multi-layer shell, it is naturally impossible to have only crew cabins inside the hull.

In addition to the standard configuration of the cockpit, power compartment, and antigravity generator as the bridge, Chen Xin also prepared a "large" comprehensive laboratory for spacecraft, as well as an ecological greenhouse.

The role of the comprehensive laboratory is of course needless to say. One of the most important purposes of space activities is to carry out various scientific experiments in space. A large comprehensive laboratory is very valuable for space activities.

Before the disaster, countries built space stations, in fact, to a large extent, in order to have a space large enough in space for scientific experiments.

As for the ecological greenhouse, on the one hand, it is also used as part of the space experiment for biological research, and on the other hand, it is used to produce food to meet the consumption of the ship.

After all, no matter how much the cost is reduced, every gram of load in space is still very valuable. It is of course the best to be able to make food self-sufficient and free up more space to carry other materials.

Under the premise of satisfying these conditions, this land-based ship came into being and was built by Chen Xin.
