Chapter 993 Complete design plan for the aerospace carrier~

"What is this?"

With some curiosity, Xu Chuan took the brown paper bag from Chang Huaxiang, untied the coil, and took out the documents inside.

After sitting down again with a smile, Chang Huaxiang picked up the kettle, added some hot water to the porcelain cups of both of them, and then spoke.

"The 'aerospace carrier' plan conceived by the Aerospace Group."

Taking a sip of hot tea, he continued: "Based on national defense deterrence and various factors, the above is preparing to build one or more large aerospace carriers."

"On the one hand, it can be used to enhance national defense. The aerospace carrier will cruise in low-Earth orbit all year round."

"On the other hand, large aerospace carriers can also serve as scientific research work, replacing traditional space stations, which is more convenient."

"At the same time, it can also serve as a transit station between the Earth and the Moon, the Earth and Mars and other planets, and even undertake large-scale immigration or material transportation."

"After all, thanks to our breakthrough in space shuttle technology and the construction of the Yuehuatai·Qiansheng Research Station base on the Moon, in theory For example, we already have a certain ability to migrate to other planets through deep space. "

"So the Aerospace Group proposed a related idea. They plan to build one or more "large" deep space spacecraft, which are specially used for migration activities between the Earth and the Moon, Mars and other planets."

"Of course, it also includes strengthening national defense and deterrence. "

"The Space Administration wants us to help refer to it. When Director Wu Yuankang came to you, you were busy with carbon-based chips, so you left this document. "

Xu Chuan nodded, his eyes fell on the report file in his hand, and he said, "Let me take a look first."

In fact, it is not the first time he has seen such a proposal to build a super aircraft such as an aerospace mothership.

As early as when the controlled nuclear fusion technology was completed, the above talked to him about whether it was possible to build a large aerospace mothership in low-Earth orbit based on the controlled nuclear fusion technology.

When the miniaturized fusion reactor and aerospace engine broke through later, he went to Beijing for a meeting, and relevant feasibility discussions and suggestions were also put forward at the meeting.

Although traditional aircraft carriers can freely navigate in vast seas, their action radius is ultimately restricted by the atmosphere, and the range and endurance of fighter jets are also limited.

However, aerospace carriers can cruise in space for a long time, and even maintain continuous coverage of the Earth's orbit, ready to launch strikes or defend at any time.

In terms of weapon systems, aerospace carriers are not only equipped with advanced carrier-based aircraft, but also equipped with high-tech equipment such as kinetic weapons and laser weapons, forming a multi-level firepower network that can cope with various complex and changing battlefield environments.

In terms of defense, except for theoretical laser weapons, there are currently no other weapons and equipment that can directly threaten objects in low-Earth orbit.

Even intercontinental missiles, which can break through the atmosphere and then re-enter the atmosphere, cannot directly attack satellites.

Therefore, for any country, the attraction of such a large mothership that can navigate in outer space and has unprecedented air supremacy is fatal.

After all, with the development of the times, especially today when aerospace technology is leaping forward at a high speed, in the future space battle, whoever can make a breakthrough in the space field first will win a strategic advantage and dominate the direction of the future battlefield.

Space, especially the Earth's near-Earth orbit, will also become a core area for countries to fight for every inch of land in the future.

However, the design of an aerospace carrier involves many cutting-edge scientific and technological fields.

Including but not limited to material science, propulsion technology, energy management, life support systems, and automated control, etc.

Any of these technologies is crucial, and many of them still require further breakthroughs to achieve.

And integrating these technologies to create a fully functional and stable aerospace carrier is a huge challenge.

Even today when the new space shuttle technology is realized, it is extremely difficult for them to build a large aerospace carrier.

Of course, once this aerospace carrier is successfully developed, it will have a subversive impact on the existing war pattern, leading the war space to extend from the surface of the earth to the vast universe, and opening a new era of war mode.

After all, it can not only respond quickly to crises in any corner of the earth, but also establish absolute advantages in space, and even become a vanguard of space colonization and development by controlling key space infrastructure such as communication hubs and navigation networks.

Although he is not very interested in the military field, Xu Chuan still carefully reads the documents in his hand.

The design of the large aerospace carrier proposed by the Aerospace Group this time adopts a shape similar to a ‘fidget spinner’.

In other words, you can think of it as an oversized bearing, with the main control room in the center as the inner ring, and designed as the area where the main power engine system is located.

The outer ring is the personnel living room, material storage room, auxiliary power engine, weapon defense system and other structures.

From the introduction in the report, it can be clearly seen that this is not just an aerospace carrier dedicated to national defense and deterrence, the Aerospace Group has also taken into account space immigration.

The outer ring of this aerospace carrier has a diameter of 532 meters, which is fixed to the inner ring structure through high-strength tensile material and can rotate!

Yes, although the outer ring and the inner ring are integrated, they are independent from another angle.

The rotation of the outer ring can generate centrifugal force for the spacecraft to simulate gravity.

According to the calculation of the Aerospace Group, when the outer ring of this spacecraft rotates at an angular velocity of two revolutions per minute, it is enough to ensure that humans can survive normally in the universe without suffering from space sickness.

In fact, the diameter of this outer space spacecraft with a diameter of 532 meters is not designed casually.

As we all know, in the nearly zero-gravity state in space, many mechanical instruments and meters of manned spacecraft cannot be used normally.

For example, equipment that relies on gravity to work, such as ball bearings and pendulum clocks.

More importantly, long-term weightlessness will pose a major threat to the life and health of astronauts.

On the one hand, weightlessness will cause excessive blood flow to and retention in the brain, which is easy to form blood clots and endanger life.

On the other hand, bones will gradually become loose and muscles will gradually atrophy in this environment.

In a cross-national health survey, 37 astronauts who worked in the International Space Station for a long time were found to have muscle atrophy ranging from 8% to 17%.

You should know that these professional astronauts have been receiving strict training on the ground for a long time, and can also use simple fitness equipment on the space station, but they still cannot prevent negative changes in physiological functions.

Therefore, we often see astronauts need to be carried out by rescuers after returning to Earth, which is for their health and safety considerations.

A former Red Soviet astronaut once fell and was injured because he stood up to accept flowers after leaving the cabin.

In addition, a living environment with a near-zero gravity will also have many negative effects on the astronauts' physiological functions, such as decreased sleep quality, loss of appetite, deterioration of taste, and interference with attention and judgment.

More than one astronaut has revealed that even if he is fixed in space, the floating feeling still forces him to wake up from his dreams frequently.

Similar situations will inevitably become more obvious as the time spent in space increases, thus hindering the work and life of astronauts.

It can be said that artificial gravity is the "guardian" that astronauts have long been looking forward to.

It is expected to solve the "weightlessness disease" once and for all, and help humans move towards a deeper universe with a more vigorous pace and a more fit body.

For current human science and technology, the simplest way to create artificial gravity is to simulate gravity through centrifugal force.

Anyone who has played on a carousel knows that if the carousel rotates very fast, you will feel a strong centrifugal force.

When I was a child, I watched the cartoon of Tom and Jerry, and I saw Tom being thrown out by the rotating amusement facilities and fell to the ground more than once.

In fact, humans have long known that this is the centrifugal force at work.

This virtual force makes the rotating object tend to move away from the center of rotation. This aerospace mothership is built based on this principle.

However, it is easy to create a rotating system, but in order to successfully simulate the same gravity as the earth, one must consider a problem.

That is the rotation speed.

The shorter the radius of the rotating system, the higher the rotation speed required to create the same centrifugal force as gravity.

Take the core module of the Tianhe space station launched into space as an example.

Its diameter is 4.2 meters. If you want to simulate the gravity of the earth, the rotation speed must reach 20 to 30 times per minute.

In such a high-speed space, people cannot move normally.

Because of the "Coriolis effect".

Perhaps many people have never heard of this term, and don't know what it is.

But everyone can understand it in another way.

It has another name, called "Coriolis deflection phenomenon".

Simply put, the moving path of an object in a rotating coordinate system will deflect, and the faster the rotation speed, the more obvious this deflection.

For example, in a system that rotates 20 to 30 times per minute, we just try to stand up from the chair, and we will fall to the ground. This is caused by the Coriolis effect.

The Coriolis effect cannot be completely eliminated. Even in a huge rotating system like the earth, the movement of objects will still deflect.

Therefore, the fluid in the northern hemisphere will deflect to the right, and the fluid in the southern hemisphere will deflect to the left, and the atmospheric and ocean circulation will be affected by this.

The reason why this aerospace mothership is designed with an outer ring diameter of 520 meters is that the Coriolis effect and the impact on the health of astronauts are taken into consideration.

Through experiments and calculations by medical experts, as long as the angular velocity of the outer ring structure of the mothership does not exceed two revolutions per minute when rotating, the health and normal activities of the personnel on the spacecraft can be guaranteed.

And through the calculation formula of centrifugal force [RCF=1.118*10*N*R], it can be concluded that if the gravity acceleration on the surface of the earth is to be achieved, the required centrifugal radius is about 224 meters, which is nearly 500 meters in diameter.

This is the core reason why the outer ring structure of this aerospace mothership has reached 520 meters.

Only when it reaches this level can the people living on it move relatively normally.

Of course, in addition to these designs that ensure the health and safety of the people living inside, the design of this aerospace mothership for military purposes should not be underestimated.

First of all, the inner ring!

In addition to being the core module, the inner circle provides energy and power for the entire aerospace mothership, and is also designed to be two powerful power cannons!

The design scheme adopted is almost the same as the electromagnetic railgun that Xu Chuan had participated in before.

The group of equipment experts who had previously mentioned that they wanted to build an "ultra-high-speed precision strike electromagnetic railgun" in space, and "desperately", finally designed it into this aerospace mothership in another form.

The controlled nuclear fusion reactor in the main core of the inner circle provides endless energy, and uses room-temperature superconducting materials as the track, with a full 68-meter-long acceleration barrel.

You know, the "Thor Electromagnetic Railgun" he saw in the test laboratory of the National Key Laboratory of Electromagnetic Energy Technology in Jiang Chu before was only 15 meters long, and the acceleration barrel was only 13.8 meters.

To be honest, Xu Chuan didn't know what these people wanted to do with this.

Kill the little life with one shot?

Ahem

Although this is not possible, such an exaggerated acceleration orbit is theoretically no weaker than the two nuclear bombs that Xiao Ri has.

The blank space between the outer circle and the inner circle is used to undertake the task of supplying aircraft such as space shuttles and aerospace fighters.

The high-strength tensile materials used to connect the inner and outer circles are designed into a structure similar to a pipe, and can even efficiently supply materials to aircraft through automated equipment.

In the outermost circle of the aerospace mothership, high-strength alloy materials are used as protective walls. According to the report documents, this is mainly to deal with the impact of fine dust and micrometeorites during space navigation.

After all, the aerospace mothership flies at an extremely high speed in space, and any fine dust and meteorites will cause great kinetic damage when hitting the spacecraft at an ultra-high speed.

Moreover, on the outer circle structure, at every certain distance, there are different types of weapons and equipment such as kinetic weapons, electromagnetic weapons and laser weapons designed and deployed synchronously.

These weapons on the outer circle structure mainly have the function of interception and protection to deal with the attack of enemy artillery shells and missiles.

Although currently there are no other weapons besides laser weapons that can attack equipment in low-Earth orbit.

But if long-range missiles such as intercontinental missiles are modified, they still have this ability.

And now the United States has also followed their footsteps and restarted the space shuttle, although it is far from comparable to theirs in terms of size and performance.

But small and medium-sized space shuttles are not without the ability to carry offensive weapons and equipment into the sky.

It has to be said that in the design of this aerospace mothership, the Aerospace Group has incorporated everything they can think of.
