Doomsday Bunker Upgrade Chapter 720: Spaceship

The re-upgraded research center has changed a lot in appearance compared to the original. The dome that originally covered the entrance and exit of the main building and Chen Xin’s private refuge was enlarged and became a slightly smaller city than the dome. But it is a large dome that covers the ecological greenhouse, geothermal energy tower and other supporting facilities around the entire research center.

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

And Chen Xin also purchased two sets of 3D printing equipment for the research center. With complete raw materials, these two sets of 3D printing equipment can produce all the equipment in active service in the Yan Kingdom except the land aircraft carrier and mobile base. Including small landslides.

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

This small landplane is naturally a test product that Chen Xin created to answer the question from the aerospace department.

However, the size of this land steerer is very small. Strictly speaking, it can only be regarded as a miniature land steerer, because it is only half the size of the **** land steerer, which is almost the same as the mine used by the state leased to the miners who mine. Landstriders are about as big, if not even smaller.

This land traveler is so small that it can naturally accommodate a lot less personnel. 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 cabins in the cabin. A bunk and a table, the size of a normal room.

Although there are ten cabins, under normal circumstances, two cabins are used to store supplies to increase the activity time of this land ship.

The entire ship is powered by nuclear power, and not nuclear batteries, but tiny nuclear reactors like those used in nuclear-powered trains.

This undoubtedly gives this small, purpose-built landcruiser quite a bit of power, allowing it to use plasma thrusters to send itself out of the atmosphere and into space.

The reason for the use of plasma thrusters is mainly because the core component used by the landslider to float in the air is the antigravity generator. This device can counteract the effect of gravity on the landslider, but it can do It just cancels out the gravitational force and does not generate additional lift.

At the height that is still affected by gravity, the anti-gravity 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 steerer continues to increase, the lift provided by the anti-gravity generator will become smaller and smaller until it reaches the ceiling of the land steerer.

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 for this reason that Chen Xin installed a high-power plasma thruster for it to provide enough thrust to completely launch the land-based ship 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, it will lose precious air, and the leak point will still be Becomes an extra point of force, allowing the hull to lose control.

This is one of the reasons why so far, the spacecraft built by humans are not large, because to ensure the airtightness of the spacecraft, and at the same time to make the outer shell of the spacecraft enough to withstand the harsh environment of outer space , this is an extremely severe test for both materials science and structure science.

Chen Xin can upgrade the entire land ship to a spaceship capable of interstellar voyage by means of system upgrade, but considering that this is a spacecraft to be delivered to the aerospace department, Chen Xin still tries his best to use it now. The Yan Kingdom possesses the technology that can be done to manufacture this land-cruising ship.

Fortunately, there is now 3D printing technology. This technology can directly print the shell of the entire ship without any gaps. Compared with traditional production and construction technology, it is undoubtedly necessary to ensure the airtightness of the hull. Win a lot.

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, and this is what was used in the manufacture of spacecraft before.

It’s just that these materials are so expensive even before the disaster that only the top national dishes of Blue Star can afford it. As for the post-apocalyptic present, even the best ones with comprehensive national strength recovery The Yan Kingdom 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.

Let’s not talk about it, just to produce a reactor for nuclear-powered locomotives, it also needs to use a lot of scarce resources to ensure the safety of nuclear reactors.

This is also one of the main reasons why Chen Xin built this landwalker so small, because there really isn’t enough raw material.

The raw materials granted by the state to the aerospace department, plus some of the materials they still have on hand, after Chen Xin improved the utilization rate of materials as much as possible, they could only build such a large land cruiser.

Of course, even so, this landline ship is more than fifty meters long, and it really belongs to the category of behemoths among spacecraft.

Such a large ship ~IndoMTL.com~ In addition to the need to ensure the strength of the hull and build a thick enough multi-layer hull, it is naturally impossible to have only crew cabins inside the hull.

In addition to the cockpit, power cabin, anti-gravity generator and other standard equipment used as the bridge, Chen Xin also prepared a comprehensive laboratory that is considered a “large” for spacecraft, as well as an ecological greenhouse. .

It goes without saying that the role of the comprehensive laboratory is of course. 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 large enough space 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 make food self-sufficient and free up more space to carry other materials.

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