The expert symposium held by the Venus Exploration Bureau in the Floating Module, Chapter 751 of the Nano Rise Text Volume, was held for more than a week. During this period, Huang Xiuyuan and others also used satellites in the orbit of Venus to conduct a series of simulation calculations.

In the atmosphere of Venus, the atmosphere about 40 to 70 kilometers away from the surface of Venus is a relatively adaptable area.

Huang Xiuyuan is more optimistic about the altitude, which is about the Venus atmosphere at an altitude of 60 to 65 kilometers. The atmospheric pressure here is about 50% of the atmospheric pressure at the Blue Star sea level.

Moreover, since the atmospheric gas concentration of Venus is higher than that of Blue Star, its troposphere height is around 50-62 kilometers above sea level; the middle layer of the atmosphere is between 62-120 kilometers; the thermal layer is between 120-300 kilometers, and this is also the Venus ionosphere.

In addition, in the altitude area 100 kilometers from Venus' atmosphere, there is also a thin layer of ozone.

This is why Huang Xiuyuan looked at the height of 60 to 65 kilometers in the Venus atmosphere. The air pressure here is relatively suitable and is at the junction of the troposphere and the middle layer.

The dense atmosphere of Venus raises the ozone layer, thermal layer, and ionosphere. The existence of these gas layers can effectively block solar storms and cosmic rays.

Of course, for the current federal technology, it is difficult to directly destroy the federal spacecraft unless it is a terrifying and dense gamma-ray flow or neutron flow.

Using the technology of an internal vacuum airship to create a floating city in an area of ​​60 to 65 kilometers of Venus' atmosphere is not a whimsical idea, but there have been relevant research in the human scientific community a long time ago.

In fact, in Huang Xiuyuan's idea, if it were not for the existence of a unique ecosystem, Mars would not necessarily be as good as Venus.

After all, Venus clearly has the advantage in distance, mass, gravity, and light and heat.

If it weren't for the fact that a special event broke out in Venus billions of years ago, causing slow self-transformation and the magnetic field to quickly deplete after the earth's core stagnates, resulting in the "out of control greenhouse event" that caused Venus' hell scene today.

If the rotation speed of Venus is similar to that of Blue Star, then the ambient temperature of Venus is most likely to be 30 to 50, that is, the global tropical climate.

Although according to current technology, it is basically unlikely that the Federation will restore Venus to a relatively high rotation speed.

The only way is to push an asteroid similar to that, let the asteroid hit Venus at a specific angle, increase the rotation speed of Venus and reactivate the core.

Unfortunately, this solution, let alone whether it can push such a huge asteroid. The disturbance of the overall solar system after the asteroid hit Venus is enough to make the Federation think twice before doing it.

If Venus does not hit well and affects Blue Star again, it will be like stealing chickens and losing rice.

Therefore, the current solutions are relatively conservative.

Huang Xiuyuan plans to build a floating city and then absorb the atmosphere of Venus bit by bit. On the one hand, the composition of Venus' atmosphere can be gradually adjusted to reduce the air pressure of the atmosphere; on the other hand, the gas from Venus' atmosphere can be used as raw materials.

The atmosphere of Venus contains huge carbon dioxide, sulfur dioxide, sulfuric acid, hydrogen sulfide and the like.

Among them, carbon dioxide accounts for about 96%. Such a huge carbon source, coupled with the nanotechnology mastered by the federal government, can fully apply carbon fibers, carbon nanotubes, composite carbon nanotubes and the like on a large scale.

Once a part of the raw materials is achieved, it will be a very huge acceleration for the federal development of Venus.

Just like the current moon zone, because the industrial zone of Guanghangong City can produce a large amount of raw materials, this makes the expansion of the moon zone look like a tiger's wings.

After all, if a base is transported from head to toe by Blue Star, plus the distance between Venus, it is estimated that it will not take a space base of more than 100,000 tons in less than ten years.

But with the support of Venus' local materials, it would be different. Blue Star only needs to transport some precision parts to quickly build a large base.

After half of the meeting, everyone brought in the Magic City Feike Company, as well as several companies and research institutes engaged in airship research and development.

The technology of internal vacuum airships is different from inflatable airships. The technical principles of the two are different.

The technical principle of an inflatable airship is to use gases with relatively low density and too heavy to make the airship and the atmosphere produce a buoyancy.

The technical principle of the internal vacuum airship is to use a lightweight and very high-strength material to create a vacuum ball, and use the negative pressure repulsion force to push the airship to float.

From the perspective of buoyancy, the overall buoyancy of the internal vacuum airship is higher than that of ordinary hydrogen airships and helium airships. It is neither prone to the explosion of hydrogen airships, nor does it require the consumption of scarce helium resources.

The disadvantage of internal vacuum airships is that they are material problems. They need thin and high-strength materials to maintain their negative pressure resistance structure, and they cannot take too much care.

This material, the previous composite graphene, plus silicon nanoplating, can be achieved.

A researcher calculated some data: "According to the current material, a kilogram of shell can support a vacuum of about 450 cubic meters. The payload of the forward-class spacecraft to Venus is about 400 to 600 tons."

"A 400 tons of shell material should be able to create a vacuum volume of 1.8 billion cubic meters."

Another researcher shook his head: "It's too ideal. The vacuum cavity of the airship cannot be monolithic. It must be a honeycomb compartment, otherwise if there is a loophole, the consequences will be unimaginable."

"Even if the compartment design is adopted, 400 tons of shell material should be able to create a vacuum volume of 50 million cubic meters."

"No, we also need to consider balancing the engine and various supporting equipment. These things are the big part of the transportation capacity..."

Everyone expressed their opinions, and as the discussion progressed, the design of the floating city gradually improved.

Considering the transportation capacity of the forward-class spacecraft, the weight of the first phase of the floating city was limited to about 400 tons.

They designed a floating module that can be continuously spliced.

The entire floating module includes 9 major systems, including posture balance auxiliary engine, vacuum shell, module skeleton, and control system.

The vacuum volume of this floating module is about 7 million cubic meters and consists of 7,000 vacuum cavity.

The total buoyancy that can be provided is, considering that the air pressure is about 40% of the blue star's sea level around 60 to 65 kilometers of the Venus atmosphere, and the 1 cubic vacuum volume can provide 0.4 kilograms of buoyancy, and the total buoyancy is about 2,800 tons.

Subtracting the 400 tons of weight of the floating module itself, the available weight should be about 2400 tons.

In other words, the maximum load bearing of a floating module is 2,800 tons, and the maximum load bearing that can be used is 2,400 tons.

In order to ensure the stability of the floating module, there must be a control system. The current solution of the airship design team is a controllable vacuum cavity.

It is to design part of the vacuum cavity to be able to remove the vacuum and evacuate the vacuum. When this part of the buoyancy is needed, the vacuum will be evacuated; when it is not needed, the vacuum will be evacuated.

This will enable the stability of the buoyancy of the floating module, so as not to float up and down due to changes in buoyancy.

The floating modules can be used alone or spliced ​​together to form a floating city.
