The Science Fiction World of Xueba

After sitting down, Ma Jingwu took the lead and said: "Professor Pang, I take the liberty of visiting today. I mainly have a few questions to communicate with you."

Pang Xuelin nodded and said, "Professor Ma, please tell me."

Ma Jingwu said: "Professor Pang, I have already read the electromagnetic orbital space launch system and aerospace plane project that you submitted to the leadership. I don't know about the aerospace plane project, but the project of the electromagnetic orbital space launch system, you Have you considered the current industrial strength of our country? According to the design plan of the electromagnetic rail launch system you have submitted, power supply system, forced energy storage system, superconducting linear motor, control system, superconducting rail, pulse generator, auxiliary system, this All the seven subsystems need to be re-researched, and the technical difficulty is at least ten times or even a hundred times that of our electromagnetic catapult, and the funds required are astronomical. With such a huge investment, are you sure we can really succeed?"

Pang Xuelin was slightly taken aback. He thought that Ma Jingwu's participation in this meeting should be to support him.

After all, the electromagnetic orbital ejection system project is closely related to his major. If this project can really be approved, it will undoubtedly be very beneficial to the future development of his team.

He didn't expect that Ma Jingwu expressed doubts about himself as soon as he came up.

But in this way, Pang Xuelin gave this Academician Ma a high look.

Being able to analyze and research an academic issue with such an attitude based on objective facts is rare and valuable in the current impetuous academic world.

No wonder he can achieve today's achievements.

After pondering for a moment, Pang Xuelin smiled and said, "Professor Ma, I'm at least eighty to ninety percent sure."

Ma Jingwu was slightly taken aback, and said, "Professor Pang, do you have any evidence?"

Pang Xuelin smiled and said: "Professor Ma, I remember that when you invented the multi-phase steady-state generator with stable windings to overcome the problems that have plagued the world's motor industry for many years, you were questioned by foreign experts and thought that this technology was theoretically impossible. Realization. The current situation is similar. If anyone wants to ask me for the basis, then I can only say that I can prove whether I am correct when this project is completed. Otherwise, no matter what I say, it is impossible to get everyone’s approval. But I This time I came to Beijing and brought some technical routes and solutions, if you can’t convince everyone, then I will invest personally, and I will stick to this project no matter what.”

Ma Jingwu couldn't help being taken aback, and asked in confusion, "Professor Pang, are you so confident in this project?"

Pang Xuelin smiled slightly and said: "I don't have confidence in this project, I have confidence in myself. In the same way, when I was working on Jinlong battery, I have already told the outside world."

Ma Jingwu and Guo Wenbin beside him looked at each other, a little dumbfounded.

Of course Ma Jingwu and Guo Wenbin know the story before and after the Golden Dragon battery.

Countless experts and scholars who were not optimistic about the Golden Dragon battery project, as well as the Stanford doctor Tian Hong who bet with Pang Xuelin, had their faces swollen by Pang Xuelin.

Now such a thing seems to happen again.

It's just that this time, it's not just a battle of emotions like last time.

What Pang Xuelin will face this time is the issue of competing for the right to speak in aerospace.

Once Pang Xuelin's project is approved by the state, it means that China's next investment in the launch vehicle field will be greatly reduced, and the super-heavy launch vehicle Long March 9, which is still in the research and development stage, may even be discontinued.

Ma Jingwu said: "Heroes are really young! Professor Pang, since you said that, then ignore the two questions just now. I look forward to your performance at the meeting tomorrow."

At this time,

Guo Wenbin followed suit and said, "Professor Pang, since that's the case, then we won't bother you today, let's take our leave first."

With that said, Ma Jingwu and Guo Wenbin got up one after another.

Pang Xuelin also stood up and sent the two to the door.

It wasn't until the figures of the two disappeared at the end of the corridor that Pang Xuelin returned to the room.

Seeing Pang Xuelin come in, Zuo Yiqiu, who was clearing away the tea sets in the reception room, couldn't help saying: "Professor Pang, are there really so many people who don't like your plan?"

Zuo Yiqiu has been by Pang Xuelin's side for several months. Apart from criticizing Pang Xuelin's messy private life, Zuo Yiqiu quite recognizes Pang Xuelin's ability.

In Zuo Yiqiu's eyes, Pang Xuelin completely fits the outside world's perception of him as a super genius.

Therefore, she did not understand why Pang Xuelin would encounter such resistance this time after he had made such great achievements.

Pang Xuelin smiled slightly and said, "I'm throwing away people's jobs this time, how could I be favored by others!"

Zuo Yiqiu was taken aback for a moment, and his face showed a look of surprise.

China's two major aerospace companies, one is Aerospace Science and Industry, and the other is Aerospace Science and Technology.

According to the information obtained by Pang Xuelin, regarding the electromagnetic orbit space launch project, the biggest opposition to Pang Xuelin's plan comes from the Aerospace Science and Technology Corporation.

After all, Aerospace Science and Industry is mainly engaged in missiles. Regardless of whether Pang Xuelin's electromagnetic ejection space launch system is successful or not, it will not have a great impact on them.

On the contrary, aerospace science and technology is mainly focused on launching rockets. Once the plan proposed by Pang Xuelin is successful, it will definitely deal a fatal blow to the expensive and inefficient launch vehicles.

They are happy to see their success.

What's more, the plan proposed by Pang Xuelin is not without flaws.

During dinner, the organizers of the meeting probably realized that there would be a confrontation tomorrow, so instead of holding any welcome banquet, they directly prepared a buffet for everyone.

When Pang Xuelin went there, he also ate his own food and didn't meet any acquaintances.

Early the next morning, Pang Xuelin changed into a dark blue suit, and under the guidance of the conference reception staff, he came to the meeting room of Xiangshan Hotel.

This meeting was a top-secret meeting, and the people attending the meeting were basically bigwigs in various fields. There were only about twenty people in total, so the meeting room was not big.

When Pang Xuelin entered the conference room, almost all the participants had already arrived.

Pang Xuelin also found two familiar faces, Ma Jingwu and Guo Wenbin.

After saying hello to each of them, Pang Xuelin came to the seat with his name written on it and sat down.

After about five minutes, the door of the meeting room was opened again.

This time, it was two old men who came in, one of them was wearing a dark green general's uniform with shoulders against wheat ears, and the other was a familiar face often seen on TV, wearing an ordinary plain jacket. Very kind.

Seeing the two people come in, everyone in the conference room gave a standing ovation including Pang Xuelin.

The old man in the jacket came to the top of the meeting room, lowered his hands slightly, and said with a smile: "Hi comrades, please sit down. The theme of today's meeting must be known to everyone. You are all on the scientific research fronts of our country. Leaders, your work is crucial to the future development of our country. In today's meeting, I hope that everyone can seek truth from facts and speak freely. Don't say something against your will because of sectarian opinions, and don't switch for certain interests. Stand. As for me and Lao Zhang, today we only have ears, not mouths, and we will not convey any opinions or ideas to you... Let’s get right to the point. This meeting started with a report by Academician Pang Xuelin, so Let's start with Academician Pang Xuelin."

The old man smiled and nodded towards Pang Xuelin.

Suddenly, in the conference room, everyone's eyes focused on Pang Xuelin.

Many people are secretly emotional.

At this Xiangshan meeting, the youngest among the participants was in his early fifties, and only Pang Xuelin was twenty-four years old.

I don't know what kind of height this young man can reach in the future.

Pang Xuelin smiled slightly, turning a blind eye to everyone's gaze, turned on his laptop and connected it to the projector in the meeting room.

Soon, Pang Xuelin's computer desktop appeared on the screen.

Afterwards, Pang Xuelin clicked on one of the PDF files and said with a smile: "Good morning, everyone. It is a great honor to meet you here. Not long ago, I submitted a project for the electromagnetic orbital space launch system and aerospace aircraft to the leadership." The book has caused quite a bit of controversy. In today’s meeting, I will explain to you my personal views on this project.”

"As we all know, with the strengthening of our country's comprehensive national strength, China's aerospace industry has been greatly developed in recent years, and has basically reached the level of sitting on the sidelines. Whether it is the annual space launch mission or the payload, it is step by step. The number of space launch missions in recent years has surpassed that of Russia. Although there is still a big gap between the United States and the United States, it is already on par. However, we must remember that the current space industry is more exploratory than Russia. The nature of the industry, exploring outer space through rockets, is no different from our ancestors driving canoes to explore the ocean thousands of years ago. According to current rocket launch cost estimates, the cost per unit load ranges from thousands to tens of thousands of dollars. Although the current United States such as SpaceX And other companies are trying to use reusable rocket technology to reduce the cost of space launch, but all this is just a drop in the bucket. In the future, we want to truly realize the industrialization of space, build solar power stations in space, build space factories, and conduct deep space exploration. Establishing colonies on the moon and Mars, and then exploring Europa, Titan, etc. It is simply not feasible to rely on this small sampan launch. Therefore, we must seek a low-cost and high-efficiency space launch way. This is also my original intention of proposing the Electromagnetic Orbit Space Launch System and Aerospace Shuttle project..."

Pang Xuelin paused, and continued: "The combination of electromagnetic orbit space launch and aerospace plane is undoubtedly one of the best ways to reduce the cost of rocket launch. The electromagnetic orbit gives the aerospace plane a huge initial velocity, reducing the space plane itself. fuel consumption, and lift the load. According to my estimation, using this system, the unit cost of space missions can be reduced to less than fifty dollars per kilogram. Only in this way can we send tens of thousands of tons of load into space, Only in this way can the foundation of the space industry be established.”

After Pang Xuelin finished speaking, the conference room suddenly fell silent.

At this time, an old man who was wearing glasses and approaching sixty years old said: "Academician Pang, I am Li Qingshan from the China Academy of Launch Vehicle Research Institute. Your idea is very good, but you have considered the technical difficulty of realizing this plan." and cost? Have you considered whether our current industrial base can build such a huge system? The investment required here cannot be done with hundreds of billions of dollars, at least it starts with trillions of dollars. Have you considered such a huge amount? Will the investment in our country have an impact on our country's economy, military, education, and even scientific research? What's more, as far as I know, the technical difficulties involved are far beyond our country's current level of technological development. Say, in your design plan, you mentioned that the launch track is made of an ultra-high-strength carbon fiber material, its Young's modulus is as high as 1TPa, the tensile strength is as high as 100GPa, and the specific strength is as high as 62.5GPa/(g/ cm3), which is more than ten times better than the best T1000 carbon fiber in our market, I wonder where we can find such a material?"

Pang Xuelin smiled slightly, and he recognized that the person speaking in front of him was the dean of the First Aerospace Academy (Launch Vehicle Research Institute).

"Dean Li, let me answer your last question first. The carbon nanomaterials research center of Jiangda University has already produced the material you mentioned. At present, we are further hurrying up the production process of this material in order to be able to carry out research on it. Mass production."

Li Qingshan was slightly taken aback, looked at Pang Xuelin in disbelief and said, "Academician Pang, are you joking?"

Pang Xuelin smiled lightly: "Do you think I am joking?"

"How can this be?"

Pang Xuelin smiled and said: "That kind of material, which we named the flying blade material, is made of ten thousand high-strength single-walled carbon nanotube fibers bound together. A single carbon nanotube with a diameter of 4 to 5 nanometers has a length of More than sixty meters, there is basically no defect in the tube body. This material has a wide range of uses, whether it is fused with resin to make heat insulation materials, or as a load-bearing part of an aircraft, or as an electromagnetic Ejection trajectories are sufficient to substantially improve the performance of these products."

For a while, the conference room fell silent.

At this time, another middle-aged man with slightly bald hair said: "Professor Pang, I am Yang Boyu from the Space Technology Research Institute. Even if you have solved the material problem, what about technical problems in other fields? For example, in superconducting linear motors High-temperature superconductors, large-capacity capacitors in forced energy storage devices, and ultra-large-capacity power supplies... It can be said that the performance requirements of these products are one or two orders of magnitude higher than our current best products. The difficulty of research and development inside cannot be solved by our investment of money. There are many problems that must be solved at the theoretical level before they can be solved. The time required for this is not a problem of five or ten years..."
