Huang Haojie finished the experimental log of the Electromagnetic Catapult Research Institute.

Academician Ma was discovered, and they have already made three prototypes.

The first mass projector made it possible to project a 200-kilogram object to an altitude of 13 km.

The second is a projection mass of 1.7 tons and a projection height of about 24 kilometers.

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

Of course, due to the previous two experimental prototypes, the reason why the projection height is relatively low is 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, which can make you doubt life, in a word: friction friction, like the steps of the devil.

Looking at the recent test schedule of the Institute of Electromagnetic Catapult, tomorrow, December 19, there will be a projection test schedule.

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

Huang Haojie is in the secret research institute, and continues to improve the entire mass projector system.

Superconductors at room temperature can reduce the technical and engineering difficulty of electromagnetic coils, and this reduction is very considerable.

High-strength, elastic and strong magnetic repulsion 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 is the magnetic vacuum film he abbreviated, which has a new problem in his supercomputing simulation.

The tensile problem, when the ring airship hangs the membrane cable, it will inevitably be affected by the gravity of the blue star, and the closer to the position of the ring airship, the greater the tension that needs to be withheld.

The huge tensile force, coupled with the fact that the cable itself is made of highly elastic materials, will inevitably lead to downward stretching of the cable.

During the ground test, because the cable was placed horizontally, the effect of planetary gravity was not obvious, but when it was suspended from the airship, it was perpendicular to the ground, and the planetary gravity was most obvious at this time.

How to solve this problem?

Huang Haojie thought about how to solve this problem, and after several supercomputer simulations, the final solution was to add three secondary cables of carbon nanotube fibers to the film, so that the carbon nanotube cables were the main force of tension.

However, in the next supercomputing simulation test, another problem broke out, the air resonance problem.

Severe convective weather in the troposphere, horizontal winds in the stratosphere, and strong convective weather in the mesosphere.

When the magnetic vacuum cable has not been subjected to electromagnetic stimulation and produces a vacuum pipe, the interference effect of air is not obvious due to the very small cross-section.

However, once the vacuum pipe state is excited, the cable at this time will expand to a vacuum pipe with a diameter of 200 meters, and the force area at this time will increase by thousands of times.

According to the results of the supercomputer simulation, severe convective weather may cause the pipeline to drift, and the upper part will be violently shaken due to severe convective weather.

The stratosphere is not a big problem, after all, the stratosphere is all horizontal winds.

However, the troposphere and mesosphere are definitely a big problem, and the strong convective weather in the atmosphere will seriously interfere with the stability of the vacuum pipeline, and 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 hundreds of meters high, can 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 more powerful, will reach more than 30 m/s, and the skyscraper will shake at this time.

And how do high-rise buildings resist strong winds?

In general, there are 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 pipes.

Because the shape and material of the vacuum pipe have been limited, although the cylindrical shape can effectively reduce the wind resistance, but the force 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 but meditate.

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

[Adjustments have been made.] ］

The position of the additional airship is the top of the troposphere, the bottom of the stratosphere.

"Supercomputing simulation, from no wind to strong wind, simulation tests are carried out one by one."

[Okay!] Start the mock test. ］

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 sure enough, the overall resonance phenomenon of the vacuum pipe decreased by about 34%.

But this result is still not ideal.

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

[Okay, it's being corrected...... ］

In the holographic projection, under the influence of various strong convective weather, Zhong constantly used the power system of the airship to cancel out those resonances.

[Master, the resonance has dropped to 26%, and some of the resonance power is too strong for the airship power to be completely offset.] ］

"Increase the power of the airship and minimize the resonance."

[Okay!] Adjusting ...... Start testing. ］

Adjust and test again and again, and reduce the resonance problem of the vacuum pipe to the extreme, and only about 13~15% of the resonance remains.

In order to suppress the resonance to this position, the supercomputing center has occupied 16 billion billions of computing power, and the energy consumption of the airship has been rising.

"Zhong will build a dedicated supercomputing plan with a computing power of 100 billion times." Huang Haojie commanded.

[Okay!] A plan has been established. ］

"Send the plan to Galaxy."

[Sent.] ］

Next, he was thinking about the problem of power supply, if it is estimated according to the simulation just now, the entire mass projector system will consume 13~160,000 kWh of electrical energy in one minute.

Based on the calculation of 10 minutes for a launch, it needs to consume 130~1.6 million kilowatt-hours of electricity, and it is impossible for the solar cells of the airship itself to supply such a huge amount of electricity.

In this way, it is inevitable that the ground-based storage station can supply electricity, and it is best to use superconductors at room temperature to transmit electricity.

After pondering for a while, Huang Haojie added two room temperature superconductor transmission lines to the entire mass projector system, one commonly used and one for backup.

Although this has caused the cost to soar by a large margin, the transmission advantages of room temperature superconductors are not comparable to those of conventional wires.

Constantly revising and improving, Zhong continued to use supercomputing simulation tests, and so on.

By about nine o'clock in the evening, Huang Haojie had completed the tropospheric section (0~12 kilometers above sea level), the lower stratosphere section (12~30 kilometers above sea level), and the upper stratosphere section (30~60 kilometers above sea level).

Because the atmospheric motion of the stratosphere is very regular, this reduces a lot of pressure on Zhong's calculation, and the resonance effect also drops to about 2~3%.

But the next middle layer is a tough bone.

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