In order to celebrate the initial success of the black box operation of the flying blade material reaction, Pang Xuelin and Xu Xincheng invited all members of the project team to have a big meal together in the evening.

After eating, Pang Xuelin left Wan Yi and had nearly two hours of communication on the next experimental plan before finishing today's work.

On the way back, Zuo Yiqiu, who was sitting in the passenger seat, turned back frequently, as if he was observing Pang Xuelin.

"Xiao Zuo, what's wrong?"

Pang Xuelin discovered Zuo Yiqiu's abnormality.

"I didn't ...... It's nothing. ”

Zuo Yiqiu hurriedly said.

Zuo Yiqiu has been Pang Xuelin's assistant for less than a month, and most of his understanding of Pang Xuelin comes from media reports and internal information he has seen.

Although I know that Pang Xuelin is a very powerful mathematician and materials scientist, I don't have a clear understanding of how powerful Pang Xuelin is.

It wasn't until today that I followed Pang Xuelin to the Flying Blade Material Project Team and learned about the specific goals and difficulties of this project, that I began to marvel at Pang Xuelin's talent.

The flying blade material project originated in August last year, and now it is just one year anniversary, during which Pang Xuelin studied the flying blade material at the same time, and even made the golden dragon battery, completing the proof of the Polygnac conjecture.

Is this what a super genius is capable of?

Compared with Pang Xuelin, Zuo Yiqiu feels that he has lived in vain for more than 20 years.

Pang Xuelin smiled, he naturally didn't know Zuo Yiqiu's thoughts, he just leaned on the back seat and pretended to sleep.

When Zhou Chen drove back to Binjiang Villa, it was almost eleven o'clock in the evening.

The villa was dark, and in the afternoon, Pang Xuelin called Yao Bingxia, saying that he would not go home for dinner at night, and he estimated that Yao Bingxia and Qi Xin were already asleep now.

Pang Xuelin asked Zuo Yiqiu and Zhou Chen to go back to rest, and he quietly returned to the room.

Pang Xuelin didn't turn on the light, went directly to the bathroom to take a shower, and then went to bed in the dark, and felt a warm body lying under the velvet quilt.

As soon as Pang Xuelin lifted the quilt, he felt the girl's snake-like arms hugging his neck and offering a fragrant kiss.

"Brother Xiaolin!"

"Natsu-chan?!"

Pang Xuelin was a little surprised.

Soon, a big battle quickly unfolded, and an hour later, Yao Bingxia lay on Pang Xuelin's body weakly, and her fingers circled his chest.

Pang Xuelin said with a smile: "Didn't you and Qi Xin say that you and Qi Xin would hang me for a while last night, why did you come over today?" ”

Yao Bingxia said: "Brother Xiaolin, I will return to the capital in two days." ”

"Why? Why are you going back so soon? ”

Pang Xuelin was slightly stunned.

Yao Bingxia glanced at him and said, "I'm about to start school." ”

"So Qi Xin gave you the night time?"

Yao Bingxia nodded and said, "Brother Xiaolin, after I leave, you are not allowed to mess with flowers and grass again, I will let Sister Qi Xin look at you...... In addition, if you have time, you must come to the capital to see me. ”

Feeling the kind of attachment to himself in Yao Bingxia's tone, Pang Xuelin hugged the girl tightly with some distress.

Yao Bingxia seemed to feel something, raised her head a little shyly and said, "Brother Xiaolin, do you still want it?" ”

After hesitating for a moment, Yao Bingxia bit her red lip and said, "Why don't you go next door and find Sister Xin." ”

"Silly girl, what do you want!"

Pang Xuelin said: "Hurry up and go to sleep." ”

"Hee-hee!"

Yao Bingxia was obviously very satisfied with Pang Xuelin's attitude, and hugged Pang Xuelin and gnawed hard before falling asleep in his arms.

Two days later, Yao Bingxia said goodbye to Pang Xuelin with tears in her eyes and returned to the capital.

Qi Xin naturally stayed, after the planting incident in the United States, she did not plan to continue to return to Princeton, but chose to return to the School of Economics of Jiang University to complete her master's studies, and Jiang University naturally would not set up any obstacles.

In the next month or so, Pang Xuelin focused on the carbon nanomaterials research center.

The flying blade material reaction black box control program from MOSS is surprisingly perfect.

Except for one mechanical failure caused by human causes, the reaction black box maintained good stability and reliability throughout the preparation process.

The yield rate of flying blade materials is even higher than that of the Nanomaterials Research Center of the Chinese Academy of Sciences led by Wang Miao in the three-body world.

Therefore, a month later, when a full sixty-meter-long (as I wrote in the previous chapter, ten centimeters in an hour, twenty hours a day, at least two meters can be made) flying blade material fibers appeared in front of everyone, they almost blinded everyone's eyes.

You must know that in the academic world, the best ultra-long carbon nanotube fiber materials are a team from Tsinghua University, and they have been able to prepare single-walled carbon nanotubes with a decimeter length through chemical vapor focusing method.

However, at present, they can only prepare in the laboratory, and there is no way to carry out large-scale mass production, and another more important problem is that they can only prepare a single decimeter-level carbon nanotube, and cannot carry out high-density macro preparation like Pang Xuelin.

The diameter of a single carbon nanotube is only about five nanometers, and there is no way to prepare it in macroscopic quantities, so it cannot be presented on a macroscopic scale, and naturally it is not possible to use it in reality.

What Pang Xuelin and the others made this time is a tube bundle composed of 10,000 60-meter-long ultra-long single-walled carbon nanotubes, and the technical difficulty between the two is like a moat.

"Academician Pang, the test results show that the single-walled carbon nanotube fiber we manufacture has a Young's modulus of more than 1TPa, a tensile strength of more than 100GPa, and a specific strength of 62.5GPa/(g/cm3), and the comprehensive performance is more than 10 times that of T1000 carbon fiber. In comparison, the specific strength of steel wire rope is 0.05~0.33GPa/(g/cm3), carbon fiber is 0.5~3.5GPa/(g/cm3), and polymer fiber is 0.28~4.14GPa/(g/cm3), which can be said to be the strongest material in the world. ”

Wan Yi stood beside Pang Xuelin, feeling a bit like a dream.

Last year, when Pang Xuelin announced to them that he was going to make such materials, Wanyi and they were still skeptical, feeling that it was a bit fantastical.

After all, this kind of leap forward is already a bit like black technology.

And now, watching this incredible product come to life in my own hands, the sense of accomplishment and pride that I can't do anything can match.

Pang Xuelin smiled faintly, such data was completely taken for granted in his opinion, compared to what he was going to do next, the flying blade material was just a starting point.

After pondering for a moment, Pang Xuelin turned his head and said to Wan Yi: "Professor Wan, you can make a report as soon as possible, and calculate the cost of upgrading the black box after the output increases tenfold." In addition, the paper can also be prepared and published as a co-corresponding author. ”

"Good!"

Wan Yi nodded and agreed.

……

When he returned home that night, Pang Xuelin wrote a technical report on the application prospects of flying blade materials, and asked Zuo Yiqiu to polish it and submit it.

What Pang Xuelin didn't expect was that on the third day after the report was submitted, Xu Xincheng brought two strange middle-aged men to find him, one of whom was still wearing a lieutenant general's uniform.

"Academician Pang, let me introduce to you, this is General Tao Yongchang, the commander-in-chief of the Tengyun Project, and this is the chief scientist of the Tengyun Project, Academician Guo Wenbin from the Aerospace Science and Industry Group."

"General Tao, Academician Guo, hello!"

"Hello, Professor Pang!"

"Professor Pang, it's a pleasure to meet you!"

Pang Xuelin shook hands with Tao Yongchang and Guo Wenbin one by one.

At this time, Xu Xincheng smiled and said: "General Tao, Academician Guo, if you have any needs next, talk directly to Academician Pang, I won't bother." ”

With that, Xu Xincheng left Pang Xuelin's office directly.

Pang Xuelin was slightly stunned, although he didn't know what kind of plan the Tengyun Project was, but what the aerospace science and industry did, Pang Xuelin was still very clear.

In China, there are two major state-owned enterprises in the aerospace field, one is the Aerospace Science and Technology Group Corporation, and the other is the Aerospace Science and Industry Corporation.

Among them, the main projects of the Aerospace Science and Technology Group Corporation include the Long March series rockets, the Shenzhou spacecraft and the Tiangong space station.

The main products of aerospace science and industry are Dongfeng series missiles, Changjian series cruise missiles, Hongqi series air defense missiles, Kuaizhou series solid rockets and other projects.

There is a joke on the Internet that aerospace science and technology is responsible for sending people to heaven, and aerospace science and industry is responsible for sending people to the west.

Although Pang Xuelin does not know the details of the Tengyun project, a lieutenant general from the military is the commander-in-chief of the project, an academician of aerospace science and industry is the chief scientist of the project, and Xu Xincheng shows an attitude of avoiding suspicion, which is enough to show that this project is not ordinary.

"General Tao, Academician Guo, please."

Pang Xuelin invited them to sit down on the sofa in the reception room next to his office, and soon, Zuo Yiqiu served three cups of steaming green tea, and then closed the door with a very good eye and exited the reception room.

At this time, Guo Wenbin took out a document from his briefcase and took the lead in speaking: "Professor Pang, you must have guessed that we came here today mainly for the flying blade material. This is an overview of our Tengyun engineering project, you can take a look at it first. ”

Pang Xuelin didn't take the document directly, but asked: "Academician Guo, this project should have a certain level of secrecy, is it appropriate to show me directly?" ”

Guo Wenbin and Tao Yongchang glanced at each other and said with a smile: "Professor Pang, this project has been authorized, you can access any information and documents about this project at any time, and even if you are willing to join the Tengyun project, my position as the chief scientist can be given to you at any time." ”

"That's not necessary."

Pang Xuelin took the document and flipped through it.

Soon, the expression on his face grew serious.

The Tengyun project, in fact, is a military-led aerospace aircraft project, and the main goal of this project is to build a space launch system consisting of a reusable launch vehicle and a small space shuttle by 2030.

The reusable launch vehicle carries the space shuttle to form a combined system, in the take-off phase, the turbofan engine with the best low-speed performance is used to provide power, and after rising to an altitude of 12,000 meters, it is switched to a scramjet engine adapted to high-speed flight in the atmosphere, and the launch vehicle and the space shuttle are sent to the near space of 25,000 kilometers, and when the speed is close to Mach 3, the launch vehicle is separated from the space shuttle, and the space shuttle rocket engine is started, sending it into low earth orbit, And the carrier returns to the take-off base by gliding and its own power.

According to the plan, the system can carry 50 tons of payloads, including the space shuttle, into low earth orbit at a time, and the space shuttle's cargo hold can carry about 10 tons of payload.

After reading the document in his hand, Pang Xuelin pondered for a long time, raised his head and said, "Academician Guo, you mean that you want to apply the flying blade material to this project?" ”

Guo Wenbin nodded and said: "Professor Pang, just yesterday, I saw the article you wrote to the central government about the flying blade material, to be honest, if it was written by someone else, I really don't necessarily believe it, but since this material is from your handwriting, I believe you won't say big things." Based on the data you provided in the article, I am convinced that this material will definitely be useful in the Tengyun project. Whether it is used for the main load-bearing parts of the fuselage structure, combined with resin materials to create thermal insulation, or applied to turbofan engines, ramjet engines and even rocket engines, I think this material has a lot of potential. ”

Pang Xuelin did not directly respond to Guo Wenbin's proposal, but stood up, walked to the window and thought about it.

Guo Wenbin and Tao Yongchang glanced at each other, a little puzzled.

Tao Yongchang couldn't help but say loudly: "Professor Pang, is there any problem here?" ”

Pang Xuelin turned around and smiled: "There is indeed a problem. ”

"What's the problem?"

Guo Wenbin said.

Pang Xuelin smiled: "I think the indicators of the aerospace aircraft of the Tengyun Project are set a little low?" ”

"Low?"

Guo Wenbin and Tao Yongchang looked at each other, a little unsure of what Pang Xuelin meant.

Pang Xuelin smiled and said, "Wait a minute, I have another project plan here for you to see." ”

With that, he went straight back to the office, connected to the MOSS quantum computer through his notebook, and printed out the overall design of the electromagnetic space launch system formulated by MOSS.

Twenty minutes later, Pang Xuelin took a thick stack of documents and put them in front of Guo Wenbin and Tao Yongchang.

"Academician Guo, General Tao, take a look."

Pang Xuelin obtained a full set of technical data on the aerospace electromagnetic launch system and the aerospace aircraft project from the three-body world, which has been stored in the MOSS quantum computer.

During this time, he has been asking MOSS to develop an electromagnetic launch system and aerospace aircraft project design plan that adapts to the current environment based on this set of data and the current level of China's scientific and technological strength and industrial development.

He originally planned to wait for the completion of the first phase of the Qiantang Laboratory project before taking out the project and handing it over to the senior management for discussion.

It's just that Pang Xuelin didn't expect that people from the military and aerospace science and industry would come to the door because of the aerospace aircraft project.

Therefore, Pang Xuelin decided to take out his plan in advance.

At that time, instead of wasting time and resources on the low-efficiency and high-cost space launch project such as the Tengyun Project, it is better to pull the military and aerospace science and industry into the electromagnetic space launch system project, and instead get more assistants for this project.
