Chapter 451: Mass accelerator

Li Hao saw Ma Yiming's blame and realized his mistake.
"You don't blame yourself. This kind of interdisciplinary knowledge is not a normal phenomenon," Li Hao advised.
Ma Yiming said distressedly, "This is my responsibility, and I should consider all the effects when planning.
I still do n’t have a good knowledge reserve, and I do n’t think about it. Fortunately, President Li stopped me in advance and did not make me a civilized sinner. "
When Li Hao saw Ma Yiming adjust his mood, he immediately opened the details of the mass accelerator plan.
He has known this kind of equipment before, and its principle is basically the same as that of the electromagnetic gun.
Use electromagnetic force to launch metal carriers from the earth into the universe.
Ma Yiming's information on the mass accelerator they designed appeared in his eyes.
Mass accelerator track, Ma Yiming and they proposed to build it into a straight line. If it is built into a spiral, it will greatly increase the cost.
Its orbit is a combination of vacuum magnetic levitation orbit and negative pressure orbit.
The metal carrier carrying process is divided into a vacuum acceleration stage and a pressure equilibrium stage.
The track length is about 700 kilometers, and the rated carrying acceleration is 20G.
It is expected that in the Qinghai-Tibet Plateau, the construction of mountain slopes will be mainly based on freight transportation.
After reading the information, Li Hao found that Ma Yiming's mass accelerator was feasible.
The concept of mass accelerator has already taken shape, and now major countries have not yet built it. It is because it still has many difficulties that need to be solved urgently.
Mass accelerator is not a fantasy product, every detail of it must conform to physical principles.
The ionosphere is as high as 70km, which is basically a dense area within 50km from the ground.
Any high-speed displacement object that exceeds the speed of the first universe.
There is no way to solve the problem of aerodynamic heating caused by friction with air.
Even with Yan Jin establishing a thermal balance, this problem cannot be completely solved.
The maximum speed of the mass accelerator can only run at a speed lower than the first cosmic speed.
Pneumatic heating will not only bring ultra-high temperatures, but also huge amounts of resistance.
Just like moving in the mud, each step requires a lot of energy.
In order to make the speed of the metal vehicle reach the first cosmic speed of 7.9 kilometers per second.
Metal carriers must be in orbit at a speed of more than 7.9 kilometers per second.
Ma Yiming they have calculated the speed. In the acceleration phase of the orbit, it is best to reach a speed of 10 kilometers per second.
Mass accelerator, the main construction cost is the track construction cost.
Although it is once and for all, it is a type of investment with high input and high output. As long as the construction is completed, great benefits will surely be obtained.
However, such high investment means that Qingci's technology assets are quite abundant. Li Hao looked a bit painful.
Engineers estimate that the cost of constructing such a track will cost 8 billion yuan per kilometer, or about 5.60 billion yuan.
This does not account for the annual maintenance costs and losses caused by the use of metal carriers.
Of course, this kind of cost is totally worth it. The mass accelerator track has an expected service life of up to 50 years.
Ma Yiming calculated in accordance with the profit of the aerospace industry and it only took five years to recover the investment.
Ma Yiming did not avoid it, and directly stated a major shortcoming of the mass accelerator in the file.
Mass accelerator track construction is limited in length, and the angle of entry is also limited. Metal carriers can only be launched to a specific track.
Their solution was to also build a simple mass accelerator in space.
Used to transfer metal vehicles and accelerate it to the desired target position.
After reading Ha Yiming's plan, Li Hao always felt what was missing from this plan?
He thought back carefully and immediately understood that the plan lacked basic information to support it.
He frowned, and continued to ask, "Your plan doesn't seem to be complete, and many things are talked about without details.
For example, a mass accelerator must be powered by a huge pulse power supply.
It uses vacuum magnetic levitation technology, which requires a huge amount of electricity during operation.
The mass accelerator you design runs at up to 20G.
Mass accelerators are used for freight, but there are not many items that can withstand 20G. "
Seeing sweat on his forehead, Ma Yiming confessed immediately: "General Manager Li, our previous plan was mainly the space elevator program.
The Mass Accelerator Program is just an alternative.
Its technology is not very mature, so we did not design this plan in detail, but I understand the general situation.
The reason why the space elevator program is so detailed. This is the plan, relying on the technical strength of our company, it is entirely possible to build independently.
But to build a mass accelerator, it must be done with the help of the state.
The energy of a mass accelerator can only be provided by a nuclear power plant. No other energy source can provide a huge power demand.
The pulse power supply has been resolved, and our mass accelerator uses a time-of-phase acceleration scheme.
The goods it transports are not ordinary goods, but special reinforced goods.
Maybe future space supplies will also form an industrial chain. "
"This quality accelerator really needs to cooperate with the country, with a investment of up to 5.600 billion yuan. It is not something our company can afford," Li Hao agreed.
He asked Ma Yiming again: "The technology that the mass accelerator lacks must not be as simple as you said.
Otherwise, you did not have this expression just now, let's say. What is his biggest stumbling block? I will urge the research building to try to solve this technology. "
Ma Yiming smiled awkwardly and replied, "It is still Li Zongming's attention, and the mass accelerator does have two most basic technologies as support.
One is superconducting technology. There is no superconducting technology, and 700 kilometers of electromagnetic coils. The current is very large during operation, which is easy to cause fire.
The other is the hard material used to construct the tunnel. High-speed metal carriers can cause up to 500 tons of pressure on the tunnel. "
"What you said is ultimately a matter of materials. I will urge the research building to do its best to develop these materials.
You now design an exhaustive plan, and if you need the technology of other companies, you must write it clearly.
A few days will be the day when the aerospace development council meets ~ EbookFREE.me ~ I officially submit this plan and let the whole country participate in this plan. "
Ma Yiming said excitedly: "Good President Li, I will definitely work hard to complete this plan. Let it reach a more perfect level."
Li Hao smiled when he saw Ma Yiming leaving.
As long as a mass launcher is built, it is equivalent to building a railway on Earth and space.
Can greatly promote the development of the current space industry.
Whether it is the information contained in gravitational waves or the relic space on the moon.
Everyone reminded Li Hao that the alien civilization was not too far away from him.
He can only do his utmost to promote the rapid development of the aerospace industry worldwide.
