Doomsday Bunker Upgrade Chapter 444: Airbag Ark

Chen Xin had the idea of ​​building an airship for a long time, but the first investment of the previous airship was too high, and the second cost-effectiveness was too low, and it was not suitable to meet the needs of the current country.

But the Airbag Ark is different. It is more similar to a flying shelter, somewhat similar to the lighthouse in "The Cage", but it is much simpler and easier to build than the lighthouse.

Looking through the information he had collected before, Chen Xin was also thinking about how to build this airbag.

The story he saw in the novel was too old to remember, and he had no idea how to make it.

What I can think of at the moment is the same way as building an airship, using large airbags as a source of lift.

Because if the hot air balloon is used, fuel is a big problem. Although it is said that after heating the air, the volume of the air can become larger and provide more lift, but obviously the airbag ark will take a long time. Flying, rather than landing for a while to refuel.

Chen Xin vaguely remembered that in that novel, the protagonist built a super-large airship with a load of an astonishing 800 tons. If an adult weighs 60 kilograms, this airship is enough to carry 5,000 people on it. There is still enough spare capacity to carry living materials and other necessities.

But how easy is it to build an airship that can carry 800 tons?

The largest airship ever built in human history, the Hindenburg, has a load capacity of only a few dozen tons. It is impossible to build ten airships the size of the Hindenburg, and then tie their airbags together Bar?

It doesn't matter how much resources it takes to build, the final result will be an incomparably huge behemoth, which is really not cost-effective in terms of cost and investment.

But this idea gave Chen Xin inspiration. Modern technology is not comparable to the era of Zeppelin airship construction. Light alloys can greatly reduce the total weight of the airship and provide enough support to ensure that the airbags of the airship will not be damaged. will deform.

The material used in the original Zeppelin was aluminum. Although aluminum is light, it is undoubtedly much heavier than new materials such as carbon fiber and graphene.

Scientists have already created a new graphene material in the laboratory that is lighter than a sheet of plastic but ten times stronger than steel.

If the cost issue is not considered, Chen Xin is sure to increase the load capacity of the new airship to 100 tons. In this way, it is theoretically possible to build an airbag ark that can carry a thousand people.

And backed by system upgrades, Chen Xin felt that he could try to build such an airship for personnel transportation in the southwest region when necessary.

After all, the most efficient transportation in China is the train. However, if a geological disaster occurs, the passage of the train will be greatly affected.

The same is true for airplanes. The aviation network, which has just recovered its navigability, is very dependent on airports. If there is no suitable airport for landing, even if there is an airplane, it will not be able to land, not to mention that an average airplane can only carry more than 100 people. load capacity.

As for helicopters, they can be used for search and rescue at critical moments and transport the wounded. However, if you want to transport survivors on a large scale, unless you can dispatch hundreds of them at a time, it will be a drop in the bucket.

It can be seen that it is necessary to create a vehicle with sufficient carrying capacity and terrain adaptability.

Now that he has made up his mind, Chen Xin also opened the drawing software on the workstation and began to draw design drawings.

Of course, this so-called design drawing is just a concept drawing that is not even a draft. The specific design will be perfected later. Now Chen Xin is just recording the thoughts in his mind.

It's just a concept map, and of course it's quick to draw.

Chen Xin quickly drew a cigar-shaped structure similar to a zeppelin on the screen, with a large pod underneath.

However, looking at this design, Chen Xin quickly rejected such a design.

The cigar-shaped design is not unreasonable. It can be regarded as a very classic design for airships. Even modern airships mostly follow this design. On the contrary, special-shaped airships are rare.

But what Chen Xin needs is an airbag ark with enough lift, not just an airship, so of course, enough lift and air-holding ability are what Chen Xin needs. The faster forward speed that came was dispensable for Chen Xin.

So soon, the airship shape on the drawing became a disc-like shape.

The entire airship looks more like a flying saucer. The flat circular shape makes the airship look larger. Although the length has not changed, the volume has undoubtedly increased a lot, and the total amount of gas that can be accommodated inside has also greatly increased. The weight that the airship can carry has also been increased.

Looking at the modified structure, Chen Xin painted and modified it again. After a while, the design of the airbag ark was completed.

It has a maximum diameter of 240 meters~IndoMTL.com~ The height of the entire airship is 130 meters high when it is full of gas. Chen Xin intends to use graphene material as a support and use multiple airbags to provide lift, In this way, when one airbag is damaged, the other airbags can still provide enough lift, so that the entire ark will not fall due to the damage of the airbag.

The main part of the entire airbag ark is located below the airbag. It is a multi-layered dish-shaped structure with a large upper and a lower small, which looks somewhat similar to the inverted Tower of Hanoi.

The largest floor is used as a living cabin. The structure is somewhat similar to the circular layout of the city in the Ice Age. The rooms are arranged around the center and maintain the same size and area. The design is to accommodate two people, up to 1200 people.

Further down is the living area that provides the living area and the lower layer of the power area used to ensure the normal operation and advancement of the ark. At the same time, it also has the ability to temporarily prepare the gas required for the inflation of the airbag. When necessary, Can be used for emergency refilling of airbags above the Ark.

As for the material storage part, it is placed above the living area and erected between the airbags, which can reduce the occupation of the living space.

After completing the entire design, Chen Xin couldn't help scratching his head. This thing is easy to build, but before there is no large-scale and low-cost manufacturing of lightweight materials, the investment in this thing is still too high.

Recommended, the app I've been using recently, [mimireadingapp\] cached reading and read aloud offline!

Let's not say anything else, the graphene material used as a support for the airbag is a material with excellent performance, but it is surprisingly expensive.

So you need to get cheap materials before you can make an airship? Chen Mo scratched his head, took his notebook, and wrote down the large-scale preparation of light materials.
