Chapter 821

The appearance of the upgraded Research Center has changed greatly compared with the original one. The dome that originally only covered the main building and the entrance and exit of Chen Xin's private shelter has been enlarged into a large dome that is slightly smaller than the Dome City, but covers the ecological greenhouse, geothermal energy tower and other supporting facilities around the location of the whole research center.

Moreover, the original weapon test site has also been upgraded, with larger site and more complete and advanced facilities.

In addition, Chen Xin also added two sets of 3D printing equipment for the research center. With complete raw materials, these two sets of 3D printing equipment can produce all Yanguo's active equipment except land aircraft carriers and mobile bases, including small land ships.

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

Naturally, this small land-based ship is an experimental object made by Chen Xin to answer the question of the space Department.

However, the size of this land ship is very small. Strictly speaking, it can only be regarded as a miniature land ship, because it is only half the size of the escort land ship, which is almost as large as the mining land ship rented by the state to those mining miners, or even smaller.

The land ship is so small that it can naturally accommodate a lot less personnel. Under Chen Xin's repeated simplification, the load of the land ship is 12-15 people.

There are only ten narrow cabins on board. Of course, compared with the situation that astronauts can only sit in the spacecraft and have trouble turning around in the past, it is still much more generous. At least there are two bunks and a table in the cabin, which is the size of a normal room.

Although there are ten compartments, under normal circumstances, two compartments will be used to store materials to improve the activity time of the land ship.

The whole ship is driven by nuclear power, and it is not a nuclear battery, but a miniature nuclear reactor used on a nuclear powered train.

This undoubtedly provides sufficient power for the special small land ship, so that it can 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 for the floating of land-based ships is the anti gravity generator. This equipment can counteract the influence of gravity on land-based ships, but what it can do is counteract each other with gravity and can not produce additional lift.

At the altitude still affected by gravity, the anti gravity generator can effectively offset the influence of gravity and allow the land ship to adjust the flight altitude at will.

However, if the height of the land ship continues to increase, the lift provided by the anti gravity generator will be smaller and smaller until it reaches the lifting limit of the land ship.

Although this ceiling is close to breaking through the atmosphere into space in a sense, the small land ship can't break through the atmosphere without the help of additional lift.

It is for this reason that Chen Xincai installed a high-power plasma propeller to provide enough thrust to send the land ship into space.

If you want to go into space, thrust alone is not enough. After all, there is a vacuum in space. Land ships must ensure that the hull is completely sealed. Otherwise, if there is air leakage and precious air is lost, the air leakage point will become an additional force application point, making the hull out of control.

This is one of the reasons why so far, the spacecraft built by humans are not large, because it is necessary to ensure the tightness of the spacecraft and make the spacecraft shell enough to cope with the harsh environment of outer space, which is an extremely severe test for both materials and structure.

Although Chen Xin can upgrade the whole land ship into a spaceship capable of interstellar navigation by means of system upgrading, considering that it is a spacecraft to be delivered to the space Department, Chen Xin still uses the technology that Yanguo has and can do to build the land ship as much as possible.

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

As for the hull materials of the land ship, Chen Xin doesn't have to worry about it. The Aerospace Department has come up with the best material formula in their hands, which was previously used in spacecraft manufacturing.

However, even before the disaster, the price of these materials was so expensive that it was amazing. Even the dishes of the top countries of Bluestar could afford it. As for now after the end of the world, even the best country with the current comprehensive national strength recovery could not be taken out so easily.

Of course, countries with reserves of raw materials are not without them, but these raw materials themselves are scarce resources. In addition to the aerospace sector, there is also a great demand in other departments and fields.

Far from it, just the reactor for producing nuclear powered locomotives also needs to use a large number of scarce resources to ensure the safety of nuclear reactors.

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

The raw materials granted by the state to the Aerospace Department, together with some of the materials they still have on hand, can only build such a large land ship after Chen Xin improves the utilization rate of materials as much as possible.

Of course, even so, the length of this land-based ship is more than 50 meters long. It really belongs to the category of giants in spacecraft.

For such a large ship, except for the multi-layer shell with sufficient thickness to ensure the strength of the hull, it is naturally impossible to have only the crew cabin inside the hull.

In addition to the standard configuration of the bridge's cockpit, power cabin and anti gravity generator, Chen Xin also prepared a "large" comprehensive laboratory for spacecraft and an ecological greenhouse.

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

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

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

After all, even if the cost is reduced, every gram of load in space is still very valuable. It is certainly the best to make food self-sufficient and free more space to carry other materials.

On the premise of meeting these conditions, the land ship came into being and was built by Chen Xin.
