Chapter 451: Mass Accelerator

Li Hao saw that Ma Yiming blamed himself a little and realized his mistake.

"Don't blame yourself, it's normal for you to not know this kind of interdisciplinary knowledge." Li Hao persuaded.

Ma Yiming said with a sullen face: "This is my responsibility, and all the effects should be taken into account when making plans."

I still don't have enough knowledge, and I don't think about the problem well. Fortunately, Mr. Li stopped me in advance and didn't make me a civilized sinner. ”

Li Hao saw Ma Yiming adjusting his mood on the side, and he immediately opened the details of the quality accelerator plan.

He had also learned about this equipment before, and its principle was basically the same as that of an electromagnetic gun.

Uses electromagnetic force to launch metal vehicles from Earth into space.

Ma Yiming's mass accelerator data appeared in front of him.

The mass accelerator of the track, Ma Yiming they proposed to build into a straight line. If it is built in a spiral shape, it will greatly increase the cost.

Its orbit is a combination of vacuum magnetic levitation track and negative pressure track.

The metal carrier carrying process is divided into a vacuum acceleration phase and a barometric equilibrium phase.

The length of the track is about 700 km, and the rated carrying acceleration is 20g.

It is expected that on the Qinghai-Tibet Plateau, with the help of mountain slopes, it will be mainly built by freight.

After reading the information, Li Hao found that the quality accelerator designed by Ma Yiming had a certain feasibility.

The concept of mass accelerators has long been formed, and now major countries have not built them. It is because it still has many difficulties that need to be solved urgently.

The mass accelerator is not a fantasy product, and every detail of it must conform to the principles of physics.

The ionosphere is up to 70 km high, and basically within 50 km above the surface is an atmospheric dense area.

Any high-velocity displacement object whose velocity exceeds the first cosmic velocity.

There is no way to solve the atmospheric pneumatic heating formed by friction with air.

Even if there is a heat balance established by Yanjin, this problem cannot be completely solved.

The mass accelerator maximum speed can only operate at a speed lower than the first cosmic speed.

Pneumatic heating not only results in ultra-high temperatures, but also in terms of resistance.

It's like moving through mud, and 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 vehicles must travel at speeds of more than 7.9 km/s in orbit.

Ma Yiming and they have calculated the speed, and it is best to reach a speed of 10 kilometers per second during the acceleration phase of the orbit.

The main construction cost of the mass accelerator is the track construction cost.

Although it is a one-and-done investment, it is a high-input and high-output type of investment. As long as the construction is completed, it will definitely obtain great benefits.

But this kind of high investment means that Qingci has a lot of scientific and technological assets. Li Hao looked a little painful.

Engineers estimate that it will cost 8 billion Chinese dollars per kilometer, or about 5.6 trillion Chinese dollars, to build such a track.

And that's not even counting the annual maintenance costs, wear and tear caused by the use of metal vehicles.

Of course, this expense is completely worth it, the mass accelerator track, which is expected to have a service life of up to 50 years.

Ma Yiming: According to the profit calculation of the aerospace industry, it only takes five years to recover the investment.

Ma Yiming did not shy away from them, and directly said a major shortcoming of the mass accelerator in the document.

Due to the limited length and orbital angle of the mass accelerator orbit, the mass accelerator orbit construction can only launch metal vehicles into a specific orbit.

Their solution was to build a simple mass accelerator in space.

Used to relay metal vehicles and accelerate them to the desired target location.

After Li Hao finished reading Ma Yiming's plan, he always felt that what was missing in this plan?

When he thought about it, he 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 a lot of things are talked about in general terms without specific details.

For example, mass accelerators must be powered by a large pulsed power supply.

It uses vacuum magnetic levitation technology, which requires a huge amount of electrical energy to operate.

The mass accelerator you designed runs at speeds of up to 20g.

The mass accelerator is used for cargo transportation, but there are not many items that can withstand 20 g. ”

Ma Yiming saw sweat on his forehead, and he immediately confessed: "Mr. Li, our previous plan was mainly the space elevator plan.

The Quality Accelerator Program is an alternative.

Its technology is not very mature, so we don't have a detailed design plan, but I know the general situation.

The reason why the space elevator program is so detailed is that it is so detailed. It is this plan, relying on the technical strength of our company, that it can be built independently.

But if you want to build a quality accelerator, you have to rely on the power of the state to do it.

The energy of the mass accelerator can only be provided by nuclear power plants, and no other energy source can provide the huge demand for electricity.

The pulsed power supply has been solved, and our mass accelerator uses a time-lapse acceleration scheme.

The goods it transports are also not ordinary goods, but specially reinforced ones.

Perhaps in the future, aerospace supplies will also form an industrial chain. ”

"This quality accelerator really needs to cooperate with the state, with an investment of up to 5.6 trillion yuan. Nor is it something that our company can afford. Li Hao said approvingly.

He asked Ma Yiming again: "The technology that the mass accelerator lacks must not be as simple as you said.

Otherwise, you didn't have this expression just now, let's say. What's his biggest obstacle? I will urge the research building to try to solve this technology. ”

Ma Yiming smiled awkwardly and replied: "It's still Mr. Li's clear observation, and the mass accelerator does have two most basic technologies as support.

One is superconducting technology. There is no superconducting technology, a 700-kilometer-long electromagnetic coil. The current is very large during operation, and it is very easy to cause fire.

The other is the hard material used to construct the tunnel, which can be pressured by metal vehicles running at high speeds of up to 500 tons. ”

"What you're talking about, in the final analysis, is a matter of materials. I will urge the Research Building to do its best to develop these materials.

You now design a detailed plan and write it out if you need technology from other businesses.

In a few days will be the scheduled day for the General Assembly of the Space Development Council.

I formally submitted this plan to the whole country to participate in this plan. ”

Ma Yiming said excitedly: "Okay, Mr. Li, I will definitely work hard to complete this plan." Let it reach a more perfect level. ”

After Li Hao saw Ma Yiming leaving, a smile appeared on the corner of his mouth.

As long as a good mass launcher is built, it is equivalent to building a railway on Earth and in space.

Nengji promotes the development of the current aerospace industry.

Whether it's the information contained in gravitational waves or the relict space on the moon.

reminded Li Hao that the alien civilization was not too far away from him.

He can only do his best to promote the rapid development of the aerospace industry around the world.
