Seeing Ma Yiming blamed himself, Li Hao realized his mistake.

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

Ma Yiming said with a distressed face: "This is my responsibility, and I should consider all the impacts when making plans.

I still don't have enough knowledge reserves, and I don't think carefully about problems. Fortunately, Mr. Li stopped me in advance and did not make me a civilized sinner. "

Seeing Ma Yiming adjusting his mood, Li Hao immediately opened up the details of the mass accelerator project.

He has also known this kind of equipment before, and its principle is basically the same as that of an electromagnetic gun.

Electromagnetic force is used to launch metal vehicles from the earth into space.

The materials of the mass accelerator designed by Ma Yiming and the others appeared in front of his eyes.

The track of the mass accelerator, Ma Yiming and the others suggested building it into a straight line. If it is built in a spiral shape, the cost will be greatly increased.

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

The metal carrier carrying process is divided into a vacuum acceleration stage and an air pressure balance stage.

The track length is about 700 kilometers, and the rated carrying acceleration is 20G.

It is estimated that on the Qinghai-Tibet Plateau, it will be built with the help of the slope of the mountain, mainly for freight.

After reading the materials, Li Hao found that the mass accelerator designed by Ma Yiming and the others was feasible.

The concept of a mass accelerator has already taken shape, and major countries have not built it yet. It is because there are still many difficulties that need to be solved urgently.

A mass accelerator is not a fantasy product, and every detail of it must conform to physical principles.

The ionosphere is as high as 70km, and basically within 50km from the ground is a dense atmosphere.

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

There is no way to solve the problem of atmospheric aerodynamic heating caused by friction with air.

Even if there is Yanjin to establish heat balance, this problem cannot be completely solved.

The maximum speed of the mass accelerator can only run below the first cosmic speed.

Pneumatic heating not only brings super high temperatures, but also creates a huge amount of drag.

Like moving through mud, every 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 in excess of 7.9 kilometers per second in orbit.

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

For mass accelerators, the main construction cost is the track construction cost.

Although it is once and for all, it belongs to the type of investment with high input and high output. As long as the construction is completed, great benefits will be obtained.

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

Engineers estimate that the cost of building this kind of track will cost 8 billion Chinese yuan per kilometer, about 5.6 trillion Chinese yuan.

This does not include the annual maintenance cost and the loss caused by the use of metal carriers.

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

Ma Yiming and the others calculated based on the profits of the aerospace industry, and it only takes five years to recover their investment.

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

Due to the limited length and limited orbit angle of mass accelerator track construction, only metal vehicles can be launched to specific orbits.

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

It is used to transfer the metal vehicle and accelerate it to the desired target position.

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

He thought about it carefully, and immediately understood that this plan lacked basic data support.

He frowned, and continued to ask: "Your plan seems to be incomplete, many things are discussed in general, without specific details.

For example, a mass accelerator must be powered by a huge pulse power supply.

It uses vacuum magnetic levitation technology and requires a huge amount of electricity to operate.

The mass accelerator you designed runs at accelerations up to 20G.

The mass accelerator is used for cargo, but there are not many items that can withstand 20G. "

Seeing sweat on Ma Yiming's forehead, he immediately confessed: "Mr. Li, our previous plan was mainly the space elevator plan.

The mass accelerator program is only an option.

Its technology is not yet mature, and we have not designed this plan in detail, but I understand the general situation.

The reason why the space elevator plan was formulated in such detail. It is this plan, relying on our company's technical strength, we can completely build it independently.

But if you want to build a mass accelerator, you must rely on the power of the country to complete it.

The energy of the mass accelerator can only be provided by nuclear power plants, and any other energy sources cannot provide the huge power demand.

The pulse power supply has been solved, and our mass accelerator adopts a sub-time acceleration scheme.

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

Perhaps future aerospace supplies will also form an industrial chain. "

"This mass accelerator really needs to cooperate with the state, with an investment of up to 5.6 trillion 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 didn't have this expression just now, let's talk. What is his biggest stumbling block? I will urge the scientific research building to try my best to solve this technology. "

Ma Yiming smiled embarrassingly, and replied: "President Li is still aware of the details, the mass accelerator does have two most basic technologies as support.

One is superconducting technology. Electromagnetic coils up to 700 kilometers long without superconducting technology. The current is very large during operation, which is very prone to fire.

The other is the hard material used to build the tunnel. The high-speed metal carrier exerts a pressure of up to 500 tons on the tunnel. "

"What you said, in the final analysis, is a matter of materials. I will urge the scientific research building to do its best to develop these materials.

You design a detailed plan now, and write it down clearly if you need technology from other companies.

A few days later is the day when the Space Development Council is scheduled to hold a general meeting.

I formally submit this plan and let the whole country 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."

Li Hao smiled when he saw Ma Yiming leaving.

As long as the mass launcher is built, it is equivalent to building a railway between the earth and space.

It can greatly promote the development of the aerospace industry.

Whether it is the information contained in gravitational waves or the relic space on the moon.

They all remind Li Hao that the alien civilization is not too far away from him.

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