Chapter 445

Chen Xin had the idea of building airships for a long time, but the previous airship investment was too high in the first place and the cost performance was too low in the second place, which was not suitable for meeting the needs of the current country.

But the balloon ark is different. It is more like a shelter that can fly. Some are similar to the lighthouses in the spirit cage, but it is much simpler and easier to build than lighthouses.

Looking at the information he had collected before, Chen Xin was also thinking about how to build the air bag airship.

At the beginning, the story he saw in the novel was too long to remember clearly, and he had no idea how to make it.

At present, we can think of the same way as building airships, using large airbags as the source of lift.

Because if we use the hot air balloon, the fuel is a big problem. Although heating the air can make the volume of the air bigger and provide more lift, it is obvious that the balloon ark needs a long time to fly, rather than falling down to replenish fuel after a period of flight.

Chen Xin vaguely remembers that in that novel, the protagonist built a super large airship with an amazing load of 800 tons. If an adult weighs 60 kg, this airship is enough to carry 5000 people to live on, and has enough spare power to carry life supplies and other necessities.

But how easy is it to build an airship capable of carrying 800 tons?

The largest airship ever built in human history, the Hindenburg, has a load of only a few tens of tons. It's impossible to build ten airships of the size of Hindenburg and then tie their air bags together, isn't it?

Not to mention how much resources will be consumed to build it, the final product will be a huge giant, which is not very cost-effective in terms of cost and investment.

However, this idea inspired Chen Xin. Modern technology is not comparable to the Zeppelin era. Light alloy can greatly reduce the total weight of the airship and provide enough support to ensure that the airship's air bag will not deform.

The original Zeppelin airship was made of aluminum. Although aluminum is light, it is much heavier than carbon fiber and graphene.

Scientists have already made new graphene materials in the laboratory that are lighter than plastic sheets but ten times stronger than steel.

If the cost is not taken into consideration, Chen Xin is sure to increase the loading capacity of the new airship to 100 tons. In this way, it is theoretically possible to build an air bag ark that can carry 1000 people.

With the support of the system upgrade, Chen Xin thinks that he can try to build such an airship for personnel transportation in Southwest China when necessary.

After all, the most efficient domestic transportation is still the train, but in case of geological disasters, the train traffic will be greatly affected. Once the railway line is broken, there will be no way to go anywhere.

The same is true for airplanes. The aviation network, which has just recovered its navigable capacity, relies heavily on airports. If there is no suitable airport for landing, even if there are airplanes, they will not be able to land, not to mention that ordinary airplanes can only carry more than 100 people.

As for helicopters, it's not far from being used to search and rescue and transport the wounded at the critical moment. But if you want to transport the survivors on a large scale, unless you can dispatch hundreds of them at a time, it's just a drop in the bucket.

Therefore, it is necessary to build a vehicle with enough 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, the so-called design drawing is just a concept drawing that can't even be considered as a draft. The specific design will be improved only after it is completed. Now Chen Xin just records the ideas in his mind.

It's just a concept map. It's very fast, of course.

Chen Xin quickly drew a cigar like structure similar to the Zeppelin airship on the screen, with a large pod underneath.

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

The design of cigar type is not unreasonable, which can be regarded as a very classic design for airships. Even modern airships mostly follow this design, but special-shaped airships are rare.

But what Chen Xin needs is an air bag ark with enough lift, not just an airship. Of course, enough lift and stagnation capacity are what Chen Xin needs. The faster forward speed brought to the cigar airship is optional for Chen Xin.

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

The whole airship looks more like an airship. The flat circular shape makes the airship look bigger. Although the length has not changed, the volume has undoubtedly increased a lot, the total amount of gas that can be contained inside has also increased greatly, and the weight that the airship can carry has also been improved.

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

It has a maximum diameter of 240 meters, and the height of the whole airship is 130 meters when it is full of gas. Chen Xin plans to use graphene material as a support and use multiple airbags to provide lift. In this way, when one airbags is damaged, other airbags can also provide enough lift, so that the whole Ark will not fall because of the damage of the airbags.The main part of the air bag ark is located below the air bag. It is a multi-layer dish structure with big top and small bottom. It looks like 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 to maintain the same size and area. The design can accommodate two people, with a maximum capacity of 1200 people.

Further down is the living area and the power area at the bottom to ensure the normal operation and progress of the ark. At the same time, it also has the ability to temporarily prepare the gas required for the air bag inflation. When necessary, it can supply emergency gas for the air bag 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 living space.

But after finishing the whole design, Chen Xin can't help scratching his head. It's easy to make this thing, but the investment in this thing is still too high before large-scale and low-cost manufacturing of light materials.

Apart from other things, graphene, which is used as airbag support, is a kind of material with excellent performance but extremely expensive.

So before we build airbags, we need to get cheap materials? Chen Mo scratched his head, took his notebook and wrote about the large-scale preparation of light materials.
