Chapter 446: Airbag Ark

Chen Xin had the idea of building an airship for a long time, but the

previous airship was too expensive for the first time, and the second price

was too low 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 "Spirit 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 airship.

The story he saw in the novel was too long to remember, and he didn't know

exactly how to make it.

At present, it can be thought of in the same way as the construction of

airships, using large airbags as a source of lift.

Because if the hot air balloon is used, the fuel is a big problem. Although

the volume of the air can be made larger and provide more lift after heating

the air, it is obvious that the airbag ark needs a long time to fly. Rather

than flying for a while and then landing to refuel.

Chen Xin vaguely remembered that in that novel, the protagonist built a super-

large airship with an astonishing load of 800 tons. Based on an adult weighing

60 kilograms, this airship is enough to carry 5,000 people on it. There is

enough spare capacity to carry daily supplies and other necessities.

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

The largest airship built in the history of mankind, the Hindenburg, has a

load of only a few dozen tons. It is impossible to build ten airships of the

size of the Hindenburg and then tie their airbags together, right?

Not to mention how much resources it needs to build, the final result will be

an extremely huge behemoth, which is really not worthwhile in terms of cost

and investment.

But this idea gave Chen Xin inspiration. Modern technology is not comparable

to the era when Zeppelin was built. Light alloys can greatly reduce the total

weight of the airship while providing sufficient support to ensure that the

airship's airbag will not be deformed.

The original Zeppelin airship used aluminum. Although aluminum is light, it is

undoubtedly much heavier than new materials such as carbon fiber and graphene.

Scientists have already produced in the laboratory a new type of graphene

material that is lighter than plastic sheets, but ten times tougher 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 completely

possible to build an airbag ark that can carry a thousand people.

And with system upgrades as a backing, Chen Xin felt that he could try to

build such an airship for personnel transportation in the southwest region

when necessary.

After all, at present, the most efficient domestic transportation is still

trains, but if geological disasters occur, train traffic will inevitably be

greatly affected. Once the railway line is broken, it will be impossible to go

anywhere.

The same is true for airplanes. The aviation network that has just regained

navigation capabilities 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 ordinary airplanes can only carry more than a

hundred people. .

As for helicopters, they can be used for search and rescue at critical moments

to transport the wounded. However, if you want to transport survivors on a

large scale, unless you can dispatch hundreds of them at once, it will be a

drop in the bucket.

It can be seen that it is necessary to make a vehicle with sufficient carrying

capacity and terrain adaptability.

Now that he had made up his mind, Chen Xin opened the drawing software of the

workstation and began to draw the design drawings.

Of course, this so-called design drawing is just a conceptual drawing that is

not even a draft. The specific design will not be perfected until later. Now

Chen Xin is only recording the thoughts in his mind.

It's just a concept map, and of course it's fast 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 drawing, 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 sufficient lift, not just an

airship, so of course, enough lift and stagnation ability are what Chen Xin

needs, which brings more to the cigar-type airship. The fast forward speed is

dispensable for Chen Xin.

So soon, the shape of the airship 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 bigger. Although the length has not changed, the volume

has undoubtedly increased a lot, and the total amount of gas that can be

contained inside has also greatly increased. The weight carried has also been

increased.

Looking at the modified structure, Chen Xin altered it again. After a while,

the airbag ark was considered complete.

It has a maximum diameter of 240 meters. The height of the entire airship is

130 meters high when filled with gas. Chen Xin intends to use graphene

materials as a support, and multiple airbags to provide lift. In this way,

when one airbag is damaged, other airbags can also provide enough lift to

prevent the entire Ark from falling 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 small bottom,

which looks somewhat similar to the inverted Tower of Hanoi.

The largest floor is used as a living cabin. The structure is 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 designed to

accommodate two people, with a maximum capacity of 1,200 people.

Further down is to provide the living area needed for life and the lower level

of the power area 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 airbag inflation. When necessary, it can be used for the Ark. The

upper air bag urgently replenishes gas.

As for the material storage part, it is placed on the living area and erected

between the airbags, which can reduce the occupation of living space.

After finishing the entire design, Chen Xin couldn't help scratching his head.

This gadget was easy to make, but before large-scale and low-cost

manufacturing of lightweight materials, the investment in this gadget was

still too high.

I recommend that the chase app I am using recently, [\Mic\Mic\Reading\app\\]

cache reading, offline reading!

Among other things, the graphene material used as a support for the airbag

alone is an amazingly expensive material although it has excellent

performance.

So before you can make an airbag airship, you need to get cheap materials?

Chen Mo scratched his head, took his notebook, and wrote on the large-scale

preparation of lightweight materials.
