Chapter 823: space ship

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.
