Doomsday Bunker Upgrade

After the re-upgrading, the research center has changed a lot from the original appearance. The dome that originally covered the main building and the entrance and exit of Chen Xin’s private refuge has been enlarged, and it has become a slightly smaller city than the dome, but it has changed The ecological greenhouse, geothermal energy tower and other supporting facilities around the entire research center are covered by a large dome.

Not only that, the original weapons 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 Yanguo's active equipment, including small land aircraft carriers and mobile bases. Line ship.

To this end, Chen Xin also deliberately opened an additional dock next to the original main building of the research center to park a small land cruiser produced.

Naturally, this small land cruiser was a test product created by Chen Xin in order to answer that question from the aerospace department.

However, the size of this land cruiser is very small. Strictly speaking, it can only be regarded as a mini land cruiser, because it is only half the size of the **** land cruiser, which is almost the same as the mining land cruiser leased by the state to those mining miners. It's almost big, or even smaller.

This land cruiser is so small that it can naturally accommodate a lot less people. Under Chen Xin's repeated simplification, this land cruiser can carry 12-15 people.

There are only ten narrow cabins on the ship. Of course, compared with the previous spacecraft where astronauts can only sit in the spacecraft and turn around, it is still a lot more generous. At least there are two upper and lower bunks in the cabin. And a table, it's the size of a normal room.

Although there are ten cabins, under normal circumstances, two cabins will be used to store materials to increase the activity time of this land cruiser.

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

This undoubtedly provides this specially-made small land cruiser with ample power, allowing it to use plasma thrusters to send itself out of the atmosphere and into space.

The reason why plasma thrusters are used is mainly because the core component used by land cruisers to float in the air is an anti-gravity generator. This equipment can offset the influence of gravity on land cruisers, but all it can do is And gravity cancels each other out, and can't generate extra lift.

At altitudes that are still affected by gravity, the anti-gravity generator can effectively counteract the effects of gravity, allowing land cruisers to adjust the flight altitude at will.

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

Although this ceiling is close to breaking through the atmosphere into space in a sense, this small land cruiser 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 cruiser completely into space.

If you want to enter space, thrust alone is not enough. After all, there is a vacuum in space. The land cruiser must ensure that the hull is completely sealed. Otherwise, once the air leaks, the precious air is lost, not to mention the leak point. The extra force point makes the hull out of control.

This is also one of the reasons why the spacecraft built by humans so far are not large, because it is necessary to ensure the airtightness of the spacecraft, and at the same time, make the outer space of the spacecraft capable of coping with the harsh environment of outer space. Whether it is material science or structural science, it is an extremely harsh test.

Although Chen Xin can upgrade the entire land vehicle into a spacecraft capable of interstellar navigation by means of a system upgrade, but considering that this is a spacecraft to be delivered to the aerospace department, Chen Xin still uses the current Yanguo Institute as much as possible. Have, can do the technology to make this land cruiser.

Fortunately, there is now 3D printing technology. This technology can directly print the hull of the entire ship without any gaps. Compared with the traditional production and construction technology, it is undoubtedly better than the traditional production and construction technology to ensure the tightness of the hull.

As for the hull materials of this land cruiser, Chen Xin doesn't need to worry about this. The aerospace department has come up with the best material formula in their hands, and this is what used to make spacecraft before.

It’s just that these materials were expensive even before the disaster to an astonishing level, and even only the top dishes of Blue Star can afford it. As for the present after the end of the world, even the best Yan country that has recovered comprehensive national strength. , It's not so easy to get it out.

Of course, it is not that there are no countries with raw material reserves, but these raw materials themselves are scarce resources. In addition to the aerospace sector, other departments and fields also have great demand.

Not to mention, it is just a reactor that produces nuclear-powered locomotives. It also requires the use of a large amount of scarce resources to ensure the safety of nuclear reactors.

This is also one of the main reasons why Chen Xin built this land cruiser so small, because the raw materials are indeed insufficient.

With the raw materials granted by the state to the aerospace sector, plus some of the materials they still have on hand, after Chen Xin increased the utilization of materials as much as possible, he could only build such a large cruiser.

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

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

In addition to the standard equipment such as the cockpit, power cabin, and anti-gravity generator of the bridge, Chen Xin also prepared a comprehensive laboratory that is considered "large" for the spacecraft and an ecological greenhouse on board.

The role of a comprehensive laboratory is naturally needless to say. One of the most important purposes of space activities is to conduct various scientific experiments in space. A large comprehensive laboratory is very precious to space activities.

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

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

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

Under the premise of meeting these conditions, this land cruiser came into being and was built by Chen Xin.
