Chapter 227 Questions
Huang Haojie finished reading the experiment log of the Institute of Electromagnetic Catapult.

It was discovered that Academician Ma and the others had made three prototypes.

The first mass projector realized the projecting of 200 kilograms of items to a height of 13 kilometers.

The second one has a projected mass of 1.7 tons and a projected height of about 24 kilometers.

As for the third one, it has just been manufactured and has not been tested yet.

Of course, the projection height of the previous two experimental prototypes is relatively low, mainly because Academician Ma's mass projector does not have a vacuum pipe.

Without the addition of vacuum pipes, the air resistance of the troposphere can make you doubt life. In a word: friction is like the pace of the devil.

I looked at the recent test arrangement of the Electromagnetic Catapult Research Institute. Tomorrow, December 12, there will be a projection test arrangement.

Rang Zhong sent a message to the Electromagnetic Catapult Research Institute, telling them that he would go to watch the projection test tomorrow.

Huang Haojie continued to improve the entire mass projector system in the secret research institute.

Room-temperature superconductors can reduce the technical and engineering difficulty of electromagnetic coils, and this reduction is very considerable.

High-strength elastic and strong magnetic repelling film can produce vacuum pipes.

Raytheon modified batteries can be used as supercapacitors.

However, Huang Haojie soon discovered another problem, that is, the high-strength elastic and strong magnetic repulsion film, which he referred to as the magnetic vacuum film. In his supercomputing simulation, a new problem appeared in this film.

As for the tension problem, when the ring-shaped airship hangs the film cable, it will inevitably be affected by the gravity of the blue star, and the closer to the ring-shaped airship, the greater the pulling force it needs to bear.

The huge pulling force and the fact that the cable itself is made of highly elastic material will inevitably lead to a downward stretching of the cable.

During the ground test, since the cables were laid horizontally, the influence of the planet's gravity was not obvious, but when it was hung from the airship, it was perpendicular to the ground, and the planet's gravity was the most obvious at this time.

how to solve this problem?
Huang Haojie thought about how to solve this problem. After several supercomputing simulations, the final solution was to add three auxiliary cables of carbon nanotube fibers to the film, so that the carbon nanotube cables are the main force to bear the tension.

However, in the next supercomputing simulation test, another problem popped up, the air resonance problem.

Strong convective weather in the troposphere, horizontal wind force in the stratosphere, and strong convective weather in the mesosphere.

When the magnetic vacuum cable has not been subjected to electromagnetic stimulation to generate a vacuum pipeline, because the cross section is very small, the interference effect of the air is not obvious.

But once the vacuum pipeline state is activated, the cable at this time will expand into a vacuum pipeline with a diameter of 200 meters, and the force-bearing area at this time will increase by thousands of times.

Judging from the supercomputing simulation results, strong convective weather may cause the pipeline to drift, and the upper half will shake violently due to strong convective weather.

The problem of the stratosphere is not so big, after all, the stratosphere is the wind force in the horizontal direction.

But the troposphere and the middle layer are definitely a big trouble. The strong convective weather in the atmosphere will seriously interfere with the stability of the vacuum pipeline. If this problem is not solved, the vacuum pipeline may be stillborn.

In fact, this resonance problem can be referred to high-rise buildings. Those buildings with a height of several hundred meters will also be affected by strong winds.

Under normal wind pressure, at a height of 10 meters from the ground, if the wind speed is 5 m/s, then at 90 meters, the wind speed can be as high as 15 m/s, and if the height reaches 300-400 meters, the wind will be even stronger. Powerful, it will reach more than 30 m/s, and at this time, skyscrapers will shake.

How do tall buildings resist strong winds?
There are generally three methods: a stronger structure, a wind damper, and a shape that effectively reduces wind resistance.

The problem is that these three methods are difficult to use for vacuum pipelines.

Because the shape and material of the vacuum pipe have been limited, although the cylindrical shape can effectively reduce the wind resistance, the stress area of ​​the vacuum pipe is too large.

Huang Haojie looked at the mass projector system simulated by the holographic projection, and couldn't help thinking hard.

"Zhong, adjust the position and number of ring-shaped airships, and add an airship at 12 kilometers away."

[The adjustment has been completed. ]
The added airship is located at the top of the troposphere and the bottom of the stratosphere.

"Supercomputing simulations, from no wind to strong wind, simulated tests one by one."

[OK!Start mock testing. ]
Zhong operated the supercomputing center to conduct a comprehensive simulation test, more than half an hour later.

Huang Haojie looked at the freshly released test results, and it turned out that the overall resonance of the vacuum pipeline had dropped by about 34%.

But this result is still not ideal.

"Zhong, you use the automatic correction of artificial intelligence to use the power on the airship to try to offset the resonance."

[Okay, auto-correction in progress...]
During the holographic projection, under the influence of various strong convective weather, Zhong continued to use the power system of the airship to offset those resonances.

[Master, the resonance has dropped to 26%. Part of the resonance force is too strong, and the power of the airship cannot be completely offset. ]
"Increase the power of the airship and suppress the resonance to a minimum."

[OK!Adjusting...starting testing. ]
After adjusting and testing again and again, the resonance problem of the vacuum pipe is weakened to the extreme, and only about 13-15% of the resonance is left.

The remaining resonances cannot be offset by the power of the airship. In order to suppress the resonance to this position, the supercomputing center has taken up 160 billion calculations, and it has also increased the energy consumption of the airship.

"Zhong will establish a dedicated supercomputing plan with a computing power of 1000 billion exascale." Huang Haojie ordered.

[OK!There are already plans in place. ]
"Send the plan to the Galaxy Group."

[Has been sent. ]
Next, he was thinking about the issue of power supply. According to the simulation situation just now, the entire mass projector system would consume 1 to 13 kilowatt-hours of electricity per minute.

Based on a 10-minute launch, it needs to consume 130 to 160 million kilowatt-hours of electrical energy. The solar cells of the airship itself cannot supply such a huge amount of electrical energy.

In this way, it is inevitable to let the storage power station on the ground supply electricity, and it is best to use room temperature superconductors to transmit electricity.

After thinking about it, Huang Haojie added two room temperature superconductor transmission lines to the entire mass projector system, one for regular use and one for backup.

Although this has caused the cost to soar a lot, the power transmission advantages of room temperature superconductors are not comparable to conventional wires.

Constantly modifying and improving, Zhong Ze continues to simulate and test with supercomputers, and so on.

到了晚上九点钟左右，黄豪杰已经完成对流层段（海拔0～12公里）、平流层下段（海拔12～30公里）、平流层上段（海拔30～60公里）。

Since the atmospheric movement in the stratosphere is very regular, this reduces a lot of pressure on Zhong's calculations, and the resonance effect is also reduced to about 2-3%.

But the next middle layer is a tough nut to crack.

The frequent strong convective weather in the middle layer is definitely a huge test for the vacuum pipeline.
