The Technology Tree of Xueba

Zhou Yu chaired the Spark Science and Technology Committee.

This meeting is the highest decision-making meeting of Spark Technology, which is responsible for formulating major technological development directions of Spark Technology.

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

He introduced the agenda of today ’s meeting and said aloud: “The main purpose of our meeting today is to help Spark Aerospace Corporation to select the main spacecraft for a period of time in the future.

If the plan is selected correctly, the future development of Xinghuo Aerospace will take a lot less 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 schemes. Qin Yuanshan and Li Qihua are invited to introduce two spacecraft schemes. "

After the breakthrough of particle electric propulsion engine and high altitude anti-gravity technology. Gradually summed up two programs with different emphasis.

The advantages and disadvantages of these two spacecraft are very obvious, and Zhou Yu cannot rush to choose one of them.

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 through multiple perspectives.

Qin Yuanshan nodded to everyone, and he began to introduce: "We are considering two design options for the spacecraft. The spacecraft I am talking about is based on particle electric propulsion engines.

It uses the particle electric push engine as the main power, and the anti-gravity technology only plays a supporting role.

Anti-gravity technology simply facilitates the takeoff of the spacecraft and prevents the particle electric push engine from falling due to the accident. "

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

Among them, there are one particle electric thrust engine at each end of the wing and the tail of the fuselage. There are three particle electric thrust engines as the power of the space shuttle.

Qin Yuanshan proudly introduced: "This is a space shuttle we designed. It has three particle electric thrust engines as power and can carry 1,200 tons of materials.

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

The shuttle's fuselage is made of high-density material, which is extremely sturdy. Even the impact of a meteorite the size of a pig will not affect the structure of the shuttle's fuselage.

The particle electric propulsion engine has enough thrust, and the space shuttle does not need to consider too complicated aerodynamic shapes.

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

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

"This solution 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 the space elevator. "

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

The space elevator occupies several hectares and it is a huge iron box.

There are particle electric push engines at the four corners of the space elevator. It uses anti-gravity technology to levitate in the air, and moves upward by the power of the particle electric push engine.

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, which rotates around the earth at the designated position.

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

After they both introduced the space shuttle and the space elevator.

Zhou Yu asked the participating scientists: "The approximate performance of these two spacecraft has been introduced, and you analyze the advantages and disadvantages of these two spacecraft from their respective perspectives."

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

But with the mechanical processing capabilities of our Spark technology, neither the shuttle nor the space elevator can stump us.

We are confident that we can produce enough reliable space equipment. "

Feng Yunde then said: "I have just carefully analyzed the materials used by the space shuttle and space elevator.

They all choose the mature technology of our materials research institute.

The production of materials for the 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 the space elevator is somewhat low, but as long as we continue to invest in research and development of this material, I believe that we will also find a way to break through this material technology. "

Yu Zhenfeng said with a frown, "I don't support space shuttles and space elevators. Now the quality projector is the better choice.

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

Particle batteries use the electronic layer to compress energy storage. There is no new breakthrough in battery theory. It is already the most efficient and convenient energy storage method.

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

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

As long as the space shuttle sacrifices a third of its payload to load the particle battery, it can still operate normally.

If there is no breakthrough in the technology of a small nuclear power plant in space elevator, it will be in the sky. "

While Zhen Feng was speaking, the smart device showed the change of the gravity parameter and energy consumption ratio during the ascent of space.

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

Seeing the growth formula of the space elevator, Zhou Yu asked in amazement: "Older than, the formula you used is so different from the formula we calculated."

Yu Zhenfeng explained with a smile: "Zhou, the space elevator is no longer a small mass object, it belongs to a large mass object.

The gravitational phenomenon produced by other celestial bodies in the space elevator cannot be ignored.

In low altitudes below 50,000 meters, it can use the idealized formula, when the gravity of the earth affected him at an efficiency of 99.9999%.

Once the space elevator exceeds 50,000 meters, the gravitational influence of other stars such as the sun and the moon will break through the 1% threshold.

This requires transforming other formulas. Anti-gravity technology equipment needs to overcome several gravitational effects at the same time, and the energy consumption will increase exponentially. "

Li Qihua looked closely at Yu Zhenfeng's formula, and he said with some frustration: "It was indeed my fault that there was a problem with the formula.

Anti-gravity equipment is affected by a variety of smaller gravitational forces, and energy consumption is substituted into the formula according to multiplication. UU reading books www.uukanshu.com did not expect it to grow exponentially. "

The situation discovered by Yu Zhenfeng almost sentenced the death penalty to the space elevator. This method could only be sealed until the energy issue was resolved.

It is also impossible to use a superconducting cable to power a space elevator, which has no possibility of practical application at all.

Zhou Yu immediately decided: "In small-scale multi-frequency transportation, the space shuttle plays a greater role.

The space elevator project is now sealed, waiting for energy supply problems to be resolved in Kaifeng.

Spark Space selected the shuttle as the new launch vehicle. "

Zhou Yu's heart is actually biased towards the space shuttle, but he cannot rashly decide the major development direction because of his preferences.

The space shuttle is more capable at this stage. 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 push engine takes off at ignition.

The space shuttle can also fly back and forth between different stars, something that a space elevator cannot do.
