Huang Junjie finished flipping through the experiment log of the Electromagnetic Ejection Research Institute.
Now Academician Ma and the others have produced three prototypes.
The first mass projector was able to project 200 kilograms of items to a height of 13 kilometers.
The second one has a projection mass of 1.7 tons and a projection height of about 24 kilometers.
As for the third one, it has just been manufactured and has not been tested yet.
Of course, the reason why the projection height of the first two experimental prototypes is relatively low is mainly because Academician Ma's mass projector does not have a vacuum pipeline.
Without the addition of vacuum pipes, the air resistance of the troposphere can make you doubt your life. In one sentence: friction and friction are like the steps of the devil.
I took a look at the recent test schedule of the Electromagnetic Catapult Research Institute. There is a launch test schedule tomorrow, December 19th.
Rang Zhong sent a message to the Electromagnetic Launch Research Institute, telling them that he would go to watch the launch test tomorrow.
Huang Junjie continued to improve the entire mass projector system in the secret research institute.
Normal temperature conductors can reduce the technical difficulty and engineering difficulty of electromagnetic coils, and this reduction is very considerable.
High-strength elastic strong magnetic repulsion film can produce vacuum pipes.
Thor modified batteries can be used as secondary capacitors.
However, Huang Haojie soon discovered another problem, that is, the high-strength elastic strong magnetic repulsion film, which he referred to as the magnetic vacuum film. This film caused a new problem in his computational simulations.
Regarding the tension issue, when the ring-shaped airship hangs the membrane 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 withstand.
The huge pulling force, coupled with the fact that the cable itself is made of highly elastic material, will inevitably cause the cable to stretch downward.
During the ground test, because the cable was placed horizontally, the influence of the planet's gravity was not obvious. However, when it was hung from the airship, it was vertical 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 simulations, the final solution was to add three auxiliary cables of carbon nanotube fibers to the film, so that the carbon nanotube cables would be the main force responsible for the tension.
However, during the next simulation test, another problem emerged, the air resonance problem.
Strong convective weather in the troposphere, horizontal wind in the stratosphere, and strong convective weather in the mesosphere.
When the magnetic vacuum cable is not subjected to electromagnetic stimulation and creates a vacuum pipe, the interference effect of the air is not obvious because the cross-section is very small.
But once the vacuum pipeline is activated, the cable will expand into a vacuum pipeline with a diameter of 200 meters, and the stress area will increase thousands of times.
Judging from the simulation results, strong convective weather may cause the pipeline to drift, and the upper part will sway violently due to strong convective weather.
The problem in the stratosphere is not big, after all, the stratosphere is dominated by horizontal winds.
But the troposphere and mesosphere are definitely a big trouble. 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 aborted.
In fact, for this resonance problem, you can refer to high-rise buildings. Those buildings hundreds of meters high will also be affected by strong winds.
Under normal wind pressure, at a height of 10 meters from the ground, if the wind is 5 meters/second, then at 90 meters, the wind can be as high as 15 meters/second. If the height reaches 3oo~4oo meters, the wind force will be even stronger
It is powerful and will reach more than 3o meters/second. At this time, the skyscrapers will shake.
How do high-rise buildings resist strong winds?
There are generally three methods: stronger structures, wind dampers, and shapes that effectively reduce 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 wind resistance, the force-bearing area of the vacuum pipe is too large.
Huang Junjie looked at the mass projector system simulated by holographic projection and couldn't help but think hard.
"Zhong, adjust the position and number of ring airships and add an airship at 12 kilometers."
[Adjustment has been completed.]
The location of the additional airship is at the top of the troposphere and the bottom of the stratosphere.
"Calculate the simulation, and conduct simulation tests one by one at each level from no wind to strong wind."
[Okay! Start simulation test.]
Zhong operated the computing center to conduct a comprehensive simulation test, more than half an hour later.
Huang Junjie looked at the fresh test results and found that the overall resonance phenomenon of the vacuum pipeline had dropped by about 34%.
However, this result is still not ideal.
"Zhong, you use the automatic correction of artificial intelligence and use the power on the airship to try to offset the resonance."
[Okay, it is being automatically corrected...]
In 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 airship power cannot be completely offset.]
"Increase the power of the airship and suppress the resonance to a minimum."
[Okay! Adjusting...starting testing.]
After adjusting and testing again and again, the resonance problem of the vacuum pipeline was reduced to the extreme, and only about 13 to 15% of the resonance was left.
The remaining resonances cannot be offset by the power of the airship. In order to suppress the resonance to this position, the computing center has occupied 160 billion times of computing power. In addition, the energy consumption of the airship has been rising.
"Zhong established a special computing plan with a computing power of 1,000 billion times." Huang Junjie ordered.
[Okay! The plan has been established.]
"Give the plan to Galaxy Group."
[Sent.]
Next, he was thinking about the issue of power supply. If it is estimated based on the simulation just now, the entire mass projector system will consume 130,000 to 160,000 kilowatt hours of electricity per minute.
Calculating that a single launch takes 10 minutes, it requires 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 use power storage stations on the ground to supply electric energy, and it is best to use normal temperature conductors to transmit electricity.
After thinking about it, Huang Haojie added two normal-temperature conductor 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 normal temperature conductors are not comparable to those of conventional wires.
Constantly revising and improving, Zhongze continued to use calculation simulation tests, and so on.
By around nine o'clock in the evening, Huang Haojie had completed the troposphere section (altitude 0 to 12 kilometers), lower stratosphere section (altitude 12 to 30 kilometers), and upper stratosphere section (elevation 3o to 6o kilometers).
Since the atmospheric motion 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 to 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 vacuum pipelines.
