Chapter 312 Two Spacecraft Plans

Zhou Yu presided over the Xinghuo Science and Technology Committee.

This meeting is the highest decision-making meeting of Spark Technology, which is responsible for drafting the major technological development direction of Fire Technology.

Zhou Yu saw that the invited scientists had arrived at the meeting site.

He introduced the agenda of today's meeting and said loudly: "The main purpose of our meeting today is to help Xinghuo Aerospace Corporation choose the main spacecraft for a period of time in the future.

If the solution is chosen correctly, the future development of Xinghuo Aerospace will avoid many detours, and we will have more funds to invest in the research and development of other projects.

After several rounds of screening in advance, we have formed two main spacecraft proposals. Next, I would like to invite Qin Yuanshan and Li Qihua to introduce the two spacecraft proposals. "

After breakthroughs in particle electric propulsion engine and high-altitude anti-gravity technology. Gradually summed up two programs with different emphases.

The advantages and disadvantages of these two spacecraft are very obvious, and Zhou Yu can't choose one of them rashly.

He decided to convene a science and technology committee to allow many scientists to discuss which solution is more conducive to the company's development from multiple perspectives.

Qin Yuanshan nodded to everyone, and he began to introduce: "We have considered two kinds of spacecraft design schemes, and the spacecraft I am talking about is mainly based on particle electric propulsion engines.

It uses the particle electric propulsion engine as the main power, and the anti-gravity technology only plays an auxiliary role.

The anti-gravity technology is only convenient for the spacecraft to take off, and prevents the particle electric propulsion engine from causing the spacecraft to fall due to an accident. "

Qin Yuanshan began to show the 3D model of this spacecraft, which is a space shuttle with a length of more than 100 meters.

There is one particle electric propulsion engine at both ends of the wing and one particle electric propulsion engine at the rear of the fuselage, and a total of three particle electric propulsion engines are used as the power of the space shuttle.

Qin Yuanshan proudly introduced: "This is the space shuttle we designed, it is powered by three particle electric propulsion engines, and can carry 1,200 tons of materials.

The space shuttle has a protective cockpit and can also transport astronauts.

The fuselage of the space shuttle is made of high-density materials, which are extremely strong. Even a meteorite impact the size of a pig will not affect the structure of the fuselage of the space shuttle.

The thrust of the particle electric propulsion engine is sufficient, and the space shuttle does not need to consider too complicated aerodynamic shape.

Our company's current technical processing capabilities can quickly process the space shuttle. "

After Qin Yuanshan introduced the space shuttle, Li Qihua came to the stage and introduced another plan to the scientists.

"This plan is based on anti-gravity technology, supplemented by particle electric propulsion engines.

It is a huge platform that can carry a maximum of 550,000 tons of materials and transport it into space. I named it a space elevator. "

Li Qihua also simultaneously showed the 3D model of the space elevator.

The space elevator covers an area of ​​several hectares, it is a huge iron box.

There are particle electric propulsion engines at the four corners of the space elevator, which use anti-gravity technology to suspend in the air, and move upward through the power of particle electric propulsion engines.

When the space elevator reaches the designated position, the anti-gravity device is turned off, allowing the gravity of the earth to recapture the space elevator, and it revolves around the earth at the designated position.

When the space elevator descends, the anti-gravity device switches the gravitational direction, allowing the earth's gravity to increase the traction on the space elevator, and it will gradually land on the earth.

After the two of them introduced the space shuttle and the space elevator.

Zhou Yu asked the scientists participating in the meeting: "The general performance of these two spacecrafts has been introduced. You can analyze the advantages and disadvantages of these two spacecrafts from your own perspectives."

Liu Jing was the first to speak: "From the perspective of mechanical design, the space shuttle is simpler.

But with our Xinghuo Technology's machining capabilities, neither the space shuttle nor the space elevator can stop us.

We are confident that we can produce sufficiently reliable aerospace equipment. "

Feng Yunde went on to say: "I just carefully analyzed the materials used in the two spacecraft, the space shuttle and the space elevator.

They all choose the mature technologies of our Materials Research Institute.

The production of materials for the space shuttle is easier, its cost is relatively low, and it can be manufactured on a large scale through nuclear power plants.

The output of some materials for space elevators is a bit low, but as long as we continue to invest in scientific research on this material, I believe that we will find a way to break through this material technology. "

Yu Zhenfeng frowned and said: "I don't support space shuttles or space elevators, the current mass projector is a better choice.

I see that these two schemes are well designed, but the only problem that is not considered is the problem of energy supply.

Particle batteries use electron layer compression to store energy. There is no new breakthrough in battery theory, and it is already the most efficient and convenient energy storage method.

Particle batteries perform very well on low-energy devices, but if you want to use them on space vehicles, it really depends on its energy density.

If you choose one of these two options, then I recommend the space shuttle.

As long as the space shuttle sacrifices one-third of its payload to carry particle batteries, it can still operate normally.

Space elevator If there is no breakthrough in the technology of small nuclear power plants, it will be far away. "

While Yu Zhenfeng was speaking, the smart device displayed the changes in the gravitational parameters and energy consumption ratio during the ascent into space.

Its energy consumption is not a linear growth, but an exponential growth curve.

When Zhou Yu saw the growth formula of the space elevator, he asked in surprise: "Old Yu, why is there such a big difference between the formula you used and the formula we calculated?"

Yu Zhenfeng explained with a smile: "Mr. Zhou, the space elevator is no longer a low-mass object, it is a large-mass object.

The phenomenon of universal gravitation produced by other celestial bodies in the space elevator cannot be ignored either.

At low altitudes below 50,000 meters, it can adopt an idealized formula, at that time the effect of the earth's gravity on him is as high as 99.9999%.

Once the space elevator breaks through 50,000 meters, the gravitational influence of the sun, the moon and other stars on it will break through the critical point of 1%.

This needs to be calculated by changing other formulas. The anti-gravity technology equipment needs to overcome several gravitational effects at the same time, and the energy consumption will increase exponentially. "

Li Qihua carefully inspected Yu Zhenfeng's formula, and he said with some frustration: "It was indeed my mistake, there was a problem in substituting the formula.

Anti-gravity equipment is affected by a variety of smaller gravitational forces, and the energy consumption is multiplied into the formula. I did not expect it to increase exponentially. "

The situation discovered by Yu Zhenfeng is almost a death sentence for the space elevator. Before the energy problem is solved, this method can only be sealed.

It is impossible to use superconducting cables to power space elevators, which has no possibility of practical application at all.

Zhou Yu immediately decided: "For small-scale multi-frequency transportation, the role of the space shuttle is greater.

The space elevator project is now sealed, waiting for the energy supply problem to be resolved before unsealing.

The Space Shuttle was chosen by the Starfire Aerospace Corporation as the new vehicle. "

Zhou Yu actually favors the space shuttle in his heart, but he cannot rashly decide on a major development direction just because of his own preferences.

The current space shuttle has stronger capabilities. It does not need to set up a special take-off site. It uses anti-gravity technology to float in the air, and the particle electric propulsion engine is ignited to take off.

The space shuttle can also fly back and forth between different stars, which is something that space elevators cannot do.
