Doomsday Bunker Upgrade

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 "Ling 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 air-bag airship.

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 needs to fly for a long time. Instead of 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 was enough to carry 5,000 people to live on it. There is enough spare capacity to carry living materials and other necessities.

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

The largest airship 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, right?

Not to mention how many resources it needs to consume 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, while providing enough support to ensure that the airbags of the airship will not be deformed.

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 new graphene materials in the lab that are 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 theoretically possible to build an airbag ark that can carry a thousand people.

And with the system upgrade as the backing, 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 domestic transportation is the train. However, if a geological disaster occurs, the passage of the train will inevitably be greatly affected.

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

As for helicopters, they can be used for search and rescue at a critical moment, and transporting the wounded is not far away, but 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 had 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. This 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 airbag ark with enough lift, not just an airship, so of course, enough lift and air-holding ability are what Chen Xin needs. Fast forward speed is 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 carried is also 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. The height of the entire airship is 130 meters high when it is full of gas. Chen Xin intends to use graphene material as support and use multiple airbags to provide lift, so that when one airbag is damaged, At times, the other airbags can also provide enough lift to prevent the entire ark from falling due to the rupture of the airbags.

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 lower, 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 and a maximum of 1,200 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, it can be used for the ark. The upper air bag is urgently replenished with gas.

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.

Just 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.

If nothing 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 airbag? Chen Mo scratched his head, took his notebook, and wrote down the large-scale preparation of light materials.

This design should be feasible in theory, but the specific values ​​require professional calculation, and ignore the unreasonable places.
