Chapter 147 The plan is now determined

"These are our current design progress for the satellite orbit, as well as relevant measurement data and detailed information. Just take a look at them and call me if you have any questions."

"Just treat this place as your own school, and don't be polite."

Xu Yuan took the thing from Xiao Xinbin and replied, "I see. Thank you, Senior Brother Xiao."

After saying that, Xu Yuan no longer hesitated. He sat down again and immersed himself in studying it seriously.

Soon it entered the deep learning state.

Xiao Xinbin, who was secretly observing Xu Yuan's situation not far away, couldn't help but feel relieved when he saw this scene.

"No wonder Junior Brother has achieved so much at such a young age. This state alone is stronger than many people."

While muttering to himself, he became more and more confident in the design and calculation of the lunar exploration satellite orbit.

Under normal circumstances, there will inevitably be an adaptation period when working in a new environment, but this did not happen to Xu Yuan. Not only did he actively ask for information for research, he was also able to devote himself to the research without being disturbed by the unfamiliar environment around him.

At least he couldn't do this.

As time passed, the rest of the people in the discussion room came out soon.

Although he saw that Xu Yuan was a little confused, he couldn't bear to disturb him because he was studying so hard.

Fortunately, Xiao Xinbin came over in time to introduce it to them.

"Professor Gao, the other party is Xu Yuan from Qinghua. Professor Chen arranged for him to participate in orbit calculation and design here."

Gao Duo is an associate researcher at the Academy of Space Technology, responsible for the calculation and design of lunar exploration satellite orbits.

After listening to Xiao Xinbin's introduction, he looked at Xu Yuan again, then retracted his gaze and said:
"Then tell him more about our current situation. I hope that with the addition of such a math genius, the progress of the work can be accelerated and not hindered."

Although he is not in the field of mathematics, he must be familiar with the name Xu Yuan.

Knowing that such math geniuses are involved in the project can help them solve many math problems.

"Don't worry, Professor Gao." Xiao Xinbin immediately assured after hearing this.

……

Xu Yuan's efficiency is naturally very high in the state of deep learning. After understanding the current progress, he has basically figured out the design and calculation of Chang'e-1's orbit.

The Space Technology Research Institute is currently adopting the plan of sending the satellite directly into the Earth-Moon transfer orbit.

It is considered to be a relatively traditional track design.

However, the disadvantage is that the satellite will suffer weight loss and other effects during large speed increment changes.

After searching the knowledge memory in his mind in detail, he decided to use a new orbital method as the satellite orbit plan. Using this orbital method can enable the satellite to gradually gain speed increments and rush towards the moon, which is more reliable than the traditional plan.

"With the existing satellite manufacturing technology, the phase modulation orbit is more suitable to ensure the smooth operation of Chang'e 1."

"Then the next step is to accurately calculate the data of the phase modulation orbit."

After quickly determining the plan based on his memory, Xu Yuan started to calculate directly.

The plan is one thing, and the precise calculation results are another.

To ensure the safe launch of the satellite into orbit, every step must be within the calculation and there must be no deviation.

Otherwise, a push adjustment will be needed.

This has a great impact on the consumption of propellant.

If the number of propulsion is too many and the propellant is consumed, subsequent work will be difficult to carry out.

Fortunately, with the measurement data provided by Xiao Xinbin, it was not too troublesome for Xu Yuan.

At least it is much simpler than proving a mathematical conjecture.

But it is worth mentioning that Xu Yuan did not directly state his phase-adjustment orbit plan, but planned to wait until all the calculations were completed before presenting this plan together to make it more convincing.

When Xu Yuan is immersed in something, he hardly feels the passage of time.

It was soon time for lunch, and it was only when I heard a familiar voice in my ear that I came back to my senses.

"Junior Brother Xu, it's time to eat. No matter how hard you work, you must pay attention to the balance between work and rest. I'll take you to taste the food in our canteen."

"Also, let me introduce you to Professor Gao."

Xu Yuan felt the strength coming from his shoulder, then raised his eyes and said with a smile: "Then I'll be waiting for your recommendation, Senior Brother Xiao." After that, he simply cleaned up the table and stood up.

The lunar exploration orbit requires multiple changes, which is quite complicated and the amount of calculation will certainly be much larger.

It can't be done in half a day.

So Xu Yuan was not in a hurry and followed Xiao Xinbin to the cafeteria of the research institute.

After all, the main job of scientific researchers is to make a living.

After getting his meal in the cafeteria, Xiao Xinbin led him to a middle-aged man. After the introduction, he found out that the other party was Professor Gao Duo, an associate researcher at the Institute of Space Technology.

It is responsible for the design and calculation of satellite orbits.

In addition to Xiao Xinbin, the entire team also includes several other postdoctoral fellows.

Because of Xu Yuan's achievements in mathematics, several people including Professor Gao Duo showed great enthusiasm.

It can be said that Xu Yuan was not treated as an outsider at all.

Xu Yuan was undoubtedly happy to see this. At least it would be much better to have a comfortable working environment.

that's it.

In the next few days, Xu Yuan basically spent the day at the Space Technology Research Institute calculating phase-modulation orbits, and only returned to his school dormitory at night.

The main consideration was that the two places were not too far apart, so it was more convenient to live in his own dormitory. As for the questions from Li Zhenya and the others, Xu Yuan just said he would help with the math problems.

……

Saturday.

A residential area in Yanjing.

Chen Yuran took advantage of the weekend to go back home. When the family was having dinner together at the dinner table in the evening, she asked Chen Jianfang next to her intentionally or unintentionally.

"dad."

"I heard that the math genius in our school has been helping out in your school recently?"

When she heard Xu Yuan say that he went to the Space Technology Research Institute, she was shocked.

After all, Xu Yuan is not aware that his father is a researcher at the Space Technology Research Institute.

The key point is that now that the two of them have met, it is even more inappropriate to talk about this matter now.

Otherwise, the two of them will meet every day, which would be awkward and would affect the progress of the project.

It’s hard to say what’s going on with Xu Yuan for now, so she can only try to find out the situation from her father indirectly.

"That's right. Originally, we needed a senior research expert in mechanics, so we went to find Professor Xu Chongxing from your school, but he sent us Xu Yuan instead."

"He also said that he has a high level of research in mechanics and can help solve problems on the project."

"How can we let anyone take on this kind of national key project? So I let him calculate the orbit. It's a win-win for both of us, as it allows him to make use of his strengths."

In response to his daughter's question, Chen Jian put down his chopsticks temporarily and couldn't help but complain a few words.

He naturally acknowledged Xu Yuan's level and talent in mathematics, but although mechanics was related to mathematics, he was obviously not competent for such an important project.

Therefore, he did not think there was anything wrong with his approach.

After hearing this, Chen Yuran didn't know what to say. She knew that Xu Yuan was studying two majors at the same time.

Although he has made considerable achievements in mathematics, I have not heard of any achievements in mechanics.

But at this moment he was definitely on Xu Yuan's side, so he took over the conversation and added a sentence.

"Xu Yuan is so talented in mathematics. Since he is also studying engineering mechanics, his level shouldn't be much different, right?"

"That's true, but he spends most of his time studying mathematics. No matter how talented he is, how much knowledge of mechanics can he master?" Chen Jianfang glanced at his daughter and explained in a deep voice.

However, Su Meihong, who was sitting opposite, looked at the father and daughter and suddenly asked Chen Yuran a question.

"Are you familiar with this Xu Yuan? It sounds like you know him well."

"Ah~"

Chen Yuran obviously didn't expect her mother to ask this suddenly. She was stunned for a moment before quickly controlling her emotions.

Pretending to be calm, he replied, "Given his fame in our school, there should be everyone who doesn't know him."

"It's a good thing that the country has such a genius." Su Meihong nodded.

Seeing that her mother did not continue to ask questions, Chen Yuran breathed a sigh of relief and continued to eat the food in front of her.

It was not until I had almost finished eating that I heard Chen Jianfang's voice again.

"Your postgraduate entrance examination results are about to come out, right?"

"Probably by the end of the month." Chen Yuran answered easily when she heard this.

She has taken the postgraduate entrance examination, and if everything goes well, she will become a graduate student of Qinghua after the summer vacation.

Although the results have not been announced yet and there will be interviews later, she is not worried about anything.

After all, she basically prepared for the postgraduate entrance examination with Xu Yuan, and she was very confident in herself as they studied together.

Chen Jianfang did not ask further questions to avoid putting pressure on his daughter, and the father and daughter understood each other tacitly to some extent.

-

Monday came in a blink of an eye.

After Xu Yuan arrived at the Space Technology Research Institute in the morning, he went to the discussion room under the guidance of Xiao Xinbin.

Participate in weekly research presentation meetings.

The main thing is that everyone reports on the progress of the work they are responsible for and sets goals for the week.

Xu Yuan had just joined the project a few days ago, so naturally he didn't need to speak at this kind of meeting.

Basically just sit in your seat and listen carefully.

"According to our current calculations, the remaining propellant for sending the satellite into the Earth-Moon transfer orbit is still too little. We are currently calculating this based on the orbital operation on the launch date."

At this time, Xiao Xinbin stood up and reported on the work progress. During his speech, it could be seen that the expressions on everyone's faces, including Professor Gao Duo, were not very good.

The main propellant is limited, and it also has to revolve around the moon. If too much is used in orbit change, subsequent related missions cannot be carried out.

This is also a problem that needs to be solved.

"Every aspect of the track must be well designed and held to the most stringent standards."

Gao Duo waved his hand to signal Xiao Xinbin to sit down first, and then emphasized the current problem again.

But at this moment, when everyone thought that there would be no new content in today's meeting, they suddenly saw Xu Yuan raise his right hand.
