After sitting down, Ma Jingwu took the lead and said: "Professor Pang, I have taken the liberty to visit today, and I mainly want to communicate with you about a few questions. ”

Pang Xuelin nodded and said, "Professor Ma, please speak." ”

Ma Jingwu said: "Professor Pang, I have already seen the electromagnetic orbital space launch system and aerospace aircraft project you submitted to the leadership, I don't know about the aerospace aircraft project, but the electromagnetic orbital space launch system project, have you considered the current industrial strength of our country?" According to your current submission of electromagnetic orbit launch system design scheme, power supply system, forced energy storage system, superconducting linear motor, control system, superconducting orbit, pulse generator, auxiliary system, these seven subsystems all need to be re-carried out scientific research, the technical difficulty is at least ten times or even more than a hundred times that of our electromagnetic catapult, the amount of money required is astronomical, such a huge investment, are you sure we can really succeed? ”

Pang Xuelin was slightly stunned, he originally thought that Ma Jingwu should support himself when he participated in this meeting.

After all, the electromagnetic orbital catapult system project is closely related to his profession, and if this project can really be established, it will undoubtedly be very beneficial to the future development of his team.

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

However, in this way, Pang Xuelin took a high look at this Academician Ma.

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

It's no wonder he's where he is today.

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

Ma Jingwu was slightly stunned and said, "Professor Pang, is there any basis?" ”

Pang Xuelin said with a smile: "Professor Ma, I remember that when you invented a multiphase steady-state generator with stable windings to overcome the problems that have plagued the world's electrical machinery industry for many years, you were questioned by foreign experts and felt that this technology was theoretically impossible to realize. It's a similar situation today, if anyone wants to ask me about the basis, then I can only say that I can't prove whether I'm right until the project is made, otherwise no matter what I say, it won't be recognized by everyone. However, I came to Beijing this time and brought some technical routes and plans, if I can't convince you. Then I'll invest personally, and I'll stick with this project anyway. ”

Ma Jingwu couldn't help but be stunned, and wondered: "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 the Golden Dragon battery, I had already said it to the outside world. ”

Ma Jingwu and Guo Wenbin beside him glanced at each other, a little crying and laughing.

The story before and after the Golden Dragon battery, of course Ma Jingwu and Guo Wenbin know.

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

Now it seems that such a thing will happen again.

Only this time, it's not just a battle of wills like last time.

This time, Pang Xuelin will face the problem 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 field of launch vehicles will be greatly reduced, and the Long March 9, a super-heavy launch vehicle that is still in the research and development stage, may even be discontinued.

Ma Jingwu said: "What a hero out of a young man!" Professor Pang, since you said so, then I didn't ask those two questions just now, and I look forward to your performance at the meeting tomorrow. ”

At this time, Guo Wenbin also said loudly: "Professor Pang, since this is the case, then we won't bother you today, and we will leave first." ”

As he spoke, Ma Jingwu and Guo Wenbin got up one after another.

Pang Xuelin also got 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 coming in, Zuo Yiqiu, who was cleaning up the tea set in the reception room, couldn't help but say loudly: "Professor Pang, are there really so many people who are not optimistic about your plan?" ”

Zuo Yiqiu has been following Pang Xuelin for several months, in addition to complaining about Pang Xuelin's messy private life, Zuo Yiqiu is quite recognized of Pang Xuelin's ability.

In Zuo Yiqiu's eyes, Pang Xuelin is completely in line with the outside world's personality of his super genius.

Therefore, she didn't understand why Pang Xuelin had already made such great achievements, and he would encounter such resistance this time.

Pang Xuelin smiled slightly and said, "I'm smashing people's jobs this time, how can I be favored!" ”

Zuo Yiqiu was slightly stunned, and his face showed a sudden look.

China's two major aerospace enterprises, one aerospace science and industry, and the other aerospace science and technology.

According to the information obtained by Pang Xuelin, with regard to the electromagnetic orbit space launch project, the largest opposition to Pang Xuelin's plan came from the Aerospace Science and Technology Group.

After all, aerospace science and industry are mainly engaged in missiles, and no matter whether Pang Xuelin's electromagnetic catapult space launch system can succeed or not, the impact on them is not very great.

On the other hand, on the side of aerospace science and technology, which mainly focuses on launching rockets, once the plan proposed by Pang Xuelin is successful, it will certainly deal a fatal blow to the expensive and inefficient carrier rockets.

They are happy to see what happens.

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

At dinner, the organizers of the conference may have realized that there would be a war of words tomorrow, and instead of holding a welcome banquet, they prepared a buffet for everyone.

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

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

This meeting is a top-secret meeting, and the participants are basically mainly bigwigs in various fields, with a total of about 20 people, so the conference room is not large.

When Pang Xuelin entered the conference room, the people attending the meeting were almost there.

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

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

After about five minutes, the door to the conference room was opened again.

This time, two old men entered, one of them was wearing a navy green general's uniform with three ears of wheat on his shoulders, and the other was a familiar face that can often be seen on TV, wearing an ordinary plain jacket, looking very kind.

Seeing the two of them come in, everyone in the conference room, including Pang Xuelin, gave a standing ovation to welcome.

The old man in the jacket came to the conference room, pressed his hands down slightly, and said with a smile: "Hello comrades, everyone sit down." The theme of today's meeting must be known to everyone, you are all leaders on various scientific research fronts in our country, and your work is very important for the future development of our country. At today's meeting, I hope that you will be able to seek truth from facts, speak your mind freely, and do not make some unintended remarks because of your opinions, nor should you change your position for the sake of certain interests. As for Lao Zhang and I, we only have ears and no mouths today, and we will not convey any opinions or ideas to everyone...... Let's go straight to the topic, this meeting began with a report by Academician Pang Xuelin, so let's start with Academician Pang Xuelin. ”

The old man smiled and nodded at 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 of 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 go in the future.

Pang Xuelin smiled slightly, ignored everyone's gaze, opened the laptop he carried with him, and connected to the projector in the conference room.

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

Subsequently, Pang Xuelin clicked on one of the PDF files and said with a smile: "Good morning, everyone, it's an honor to meet you here." Not long ago, I submitted to the leadership a project proposal for an electromagnetic orbital space launch system and an aerospace aircraft, which caused quite a bit of controversy. At today's meeting, I would like to share with you my personal views on this project. ”

"As we all know, with the enhancement of China's comprehensive national strength, China's aerospace industry has been greatly developed in recent years, and has basically reached the level of sitting on two and looking at one, whether it is the annual space launch mission or the load, it is increasing step by step, and the number of space launch missions in recent years has surpassed Russia. Although there is still a big gap between it and the United States, it can already be seen. However, we must remember that the current space industry is more exploratory than industrial, and the exploration of outer space through rockets is no different from our ancestors who drove canoes to explore the oceans thousands of years ago. According to the current rocket launch cost estimates, the cost per unit load ranges from thousands to tens of thousands of dollars. Although American companies such as SpaceX are currently trying to reduce the cost of space launches with reusable rocket technology, 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, conduct deep space exploration, establish colonies on the moon and Mars, and then explore Europa, Titan, and so on...... It is simply not feasible to rely on this kind of small sampan launch. Therefore, we must seek a low-cost and efficient way to launch space. That's why I came up with the Electromagnetic Orbit Space Launch System and the Aerospace Plane project......"

Pang Xuelin paused and continued: "The combination of electromagnetic orbital space launch and aerospace aircraft is undoubtedly one of the best ways to reduce the cost of rocket launches. According to my estimates, with this system, the unit cost of space missions can be reduced to less than $50 per kilogram, and only then will we be able to send tens of thousands of tons of payloads into space, and only in this way can we build the foundation of the space industry. ”

Pang Xuelin's voice fell, and the conference room suddenly fell silent.

At this time, an old man wearing glasses and approaching the age of sixtieth birthday spoke up: "Academician Pang, I am Li Qingshan from the China Academy of Launch Vehicles. Your idea is very good, but have you considered the technical difficulty and cost of implementing this plan? Have you ever considered whether we can build such a large system in our current industrial base? The investment required here is not 100 billion US dollars, at least it starts at trillions of US dollars, have you considered the impact of such a huge investment on our country's economy, military, education and even scientific research? What's more, as far as I know, the technical difficulty involved in this is far beyond the current level of scientific and technological development in our country, not to mention, in your design plan, you mentioned that the launch track is made of an ultra-high-strength carbon fiber material, whose Young's modulus is as high as 1TPa or more, tensile strength is as high as 100GPa or more, and the specific strength is as high as 62.5GPa/(g/cm3), which is more than ten times higher than the performance of the best T1000 carbon fiber on the market. I wonder where we can find such a material? ”

Pang Xuelin smiled slightly, he recognized the person who spoke in front of him, it was the president of the First Academy of Aerospace Science and Technology (launch vehicle research institute).

"Dean Li, let me answer your last question first, the kind of material you mentioned has been manufactured by the Jiangda Carbon Nanomaterials Research Center, and we are currently further speeding up the production process of this material, in order to be able to mass-produce it."

Li Qingshan was slightly stunned, looked at Pang Xuelin with some incredulity, and said, "Academician Pang, are you kidding?" ”

Pang Xuelin smiled faintly: "Do you think I'm joking?" ”

"How is this possible?"

Pang Xuelin smiled: "That kind of material, which we named as the flying blade material, is made of 10,000 high-strength single-walled carbon nanotube fibers, a single carbon nanotube with a diameter of 4~5 nanometers, a length of more than 60 meters, and there is basically no defect in the tube body. This material can be used in a wide range of applications, whether it is fused with resin to make thermal insulation, used as a load-bearing part of an aircraft, or used as an electromagnetic catapult trajectory, which can greatly improve the performance of these products. ”。

For a moment, 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 Academy of Space Technology, even if you have solved the material problem, what about the technical problems in other fields?" For example, high-temperature superconductors in superconducting linear motors, 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, and the difficulty of research and development in this is not something that we can solve with money, and there are many problems that must be broken through at the theoretical level before they can be solved, and the time required is not a problem of five years or ten years......"
