Time passed minute by minute, and unconsciously, it had reached the end of the half-hour agreed by Pang Xuelin.

After using seven or eight pieces of manuscript paper, Pang Xuelin finally completed the final calculation.

Finally, Pang Xuelin raised his head and said to Wang Yu and Wu Chunmin on the side: "Inform the front, within ten minutes, 123.7KG of liquid oxygen will be released, and at the same time, the liquid oxygen will be replenished, and the temperature of the pump casing should be able to reach our predetermined temperature at that time!" ”

Wang Yu and Wu Chunmin glanced at each other, Wang Yu hesitated for a moment, and asked, "Professor Pang, do you have a big grasp?" ”

Pang Xuelin smiled faintly: "Ninety percent." ”

"Good! Then I will notify the front-line operators immediately. ”

The order was quickly given.

But the atmosphere in the hall was still solemn.

Although Pang Xuelin has long been famous, everyone knows how difficult the calculation of the slip flow model is, and whether Pang Xuelin's conclusion is correct, everyone present still has question marks in their hearts.

The reason why no one stood up to stop Pang Xuelin from doing such useless work just now is that on the one hand, Pang Xuelin is famous after all, and the academic achievements of all the people here added up are not enough for Pang Xuelin to fight alone.

On the other hand, there is more or less a desire to watch jokes.

Pang Xuelin's meddling in the aerospace industry, and even directly denying the future development direction of rocket power, caused a lot of dissatisfaction in the entire aerospace industry.

But his arms can't twist his thighs, this big guy is so awesome that people in the aerospace industry can only pinch their noses and admit it.

But if Pang Xuelin interferes in the launch of the 921 rocket this time, or his plan is not effective at all, although there is no way to overturn the country's overall deployment of the aerospace industry in the future, but when facing this big man, the scholars in the aerospace industry can stand up a little straighter.

No matter how awesome you are in your own field, but in the aerospace field, you have to coil even if you are a dragon, and you have to lie down even if you are a tiger.

With this in mind, the atmosphere of the entire launch hall was solemn and at the same time, it was more or less weird.

However, those young generation of engineers are full of expectations for Pang Xuelin.

The big guy has never missed a beat, and they believe this time will be no exception.

Before I knew it, ten minutes had passed.

Wang Yu's headset suddenly came from the front call.

Wang Yu thought about it and turned on the voice directly.

"07 console report 01, the temperature of the rocket pump casing has cooled to the predetermined temperature, and the launch process can continue!"

All of a sudden, everyone's eyes on the scene focused on Pang Xuelin.

Bang Bang Bang ......

Wang Yu was the first to applaud, and then the applause resounded throughout the hall of the launch command center.

Wang Yu stepped forward and took the initiative to shake hands with Pang Xuelin and said, "Professor Pang, thank you!" Thank you! If it weren't for you today, we'd probably have to delay our project for a few more months! ”

Pang Xuelin smiled and said, "Everyone is working hard for the same goal, it should be!" Now the launch has not been completed, Mr. Wang, the next work will be handed over to you! ”

"Don't worry, we promise to send the plane into the sky beautifully."

Under the command of Wang Yu, soon, the launch command center became orderly again.

Liu Xuesong, Pang Xuelin, and Tao Yongchang also returned to their original positions and sat down.

Liu Xuesong looked at Pang Xuelin with some amazement, he is the chief engineer of the 921 rocket, although he will not go into the technical details of some projects, but he is very clear about the engineering difficulty of engine pre-cooling.

Especially before launch, the engine pre-cooling did not meet the design indicators.

Pang Xuelin actually calculated the parameters of emission pre-cooling by hand, so that the engine met the requirements before launch.

This alone is enough to show how deep the accumulation of this young man in front of him is in the basic field of mathematics, physics and chemistry.

For a while, Liu Xuesong's mood was excited and a little complicated.

He was excited that the 921 rocket could finally be launched smoothly, and his years of hard work were not wasted.

What's complicated is that the person who helped him solve the technical problems turned out to be the person he had always hated.

"Professor Pang, thanks to you this time, otherwise our team would have been in a mess!"

Liu Xuesong sighed.

Pang Xuelin smiled and said, "It's all for work, it's not a big deal." ”

Pang Xuelin could obviously feel that Liu Xuesong's attitude towards him had changed, and he didn't have any bad feelings towards Liu Xuesong, and the relationship between the two quickly became warm.

At 19:00 in the evening, in the countdown of the commander, the 921 rocket was successfully lifted off, and soon sparked heated discussions on the Internet.

After all, the 921 rocket is no less than SpaceX's Heavy Falcon in terms of load and all parameters, and this launch is China's first aerospace aircraft, which naturally attracts more attention.

There was a lot of disturbance on the Internet, but Pang Xuelin had left the Wenchang Launch Center silently and went to the central region of Hainan Province to investigate.

During this trip to Hainan, Pang Xuelin observed the launch of the 921 rocket, and a more important task was to inspect the future construction site of the electromagnetic orbital launch system.

The topography of Hainan Island is high in the middle and low in the surrounding areas, and the coastal areas from the south of the central to the surrounding areas are descended by mountains, hills, platforms and plains step by step, forming a circular layered landform, in various landform types, the mountains above 500 meters above sea level account for 25.4% of the total area of the island, the hills account for 13.3%, the platforms account for 32.6%, the terraces account for 16.9%, the plains account for 11.2%, and the others account for 0.6%, with the characteristics of terraces and terraces, the hills are densely connected, and the plains are few and scattered.

Next, Pang Xuelin spent nearly half a month traveling through the large and small towns and villages in the southwest of Hainan Island, and finally determined the circuit diagram of the electromagnetic catapult space launch system.

That is from the Yinggehai Town of Ledong County, extending to the northeast, until the Parrot Ridge in the south-central region, and at an altitude of about 1,500 meters, it reaches the end, the length of the entire electromagnetic catapult track reaches about 40 kilometers, and the estimated construction cost is 10 billion RMB per kilometer, with a total investment of more than 400 billion!

In addition, it is expected to build an aerospace aircraft return airport, maintenance and testing plants, nuclear power plants, etc., with a total investment of more than 500 billion yuan.

After the successful preparation of superconducting 128 materials, Pang Xuelin has already determined the implementation of this project with the top leadership.

It is expected to be completed within three years at the earliest, and will be invested and constructed by China Aerospace Science and Technology Corporation, China Aerospace Science and Industry Corporation, China Railway Construction Group, State Grid and other enterprises, and Pang Xuelin serves as the chief scientist of this project.

Of course, Pang Xuelin does not need to stay at the project site in real time, he only needs to come once or twice a year.

His main energy has to be put into the construction of Jiangcheng University, Qiantang Laboratory, and Jiangcheng Institute for Advanced Study.
