Chapter 149 You said you have calculated everything
"You said that you have successfully determined the satellite orbit plan. This is good news I have heard recently."

In the office, Chen Jianfang's face was full of joy. After hearing Gao Duo's report, he quickly asked him to sit down.

"Sit down quickly."

Seeing this, Xu Yuan sat down on the sofa next to Professor Gao.

After Gao Duo led the team to verify his calculation results, they had confirmed the accuracy of the orbital design plan, and decisively decided to use the phase-modulated orbit as the Chang'e-1 satellite orbit, so they couldn't wait to take him to Chen Jianfang to report.

Although Chen Jianfang's attention was on Gao Duo at the moment, Xu Yuan didn't care.

Just sat there obediently and listened to the two people talking.

"I remember you were still hesitating about the track plan before, how come you suddenly decided today?"

After Gao Duo sat down, Chen Jianfang asked curiously, "Tell me what happened here in detail."

Gao Duo did not flatter himself when he heard this. He put on a happy smile and spoke mysteriously.

"I have to thank you, Professor Chen."

"Thank me?" Chen Jianfang expressed confusion.

Just as he was about to ask more, Gao Duo turned his gaze to Xu Yuan and said, "If you hadn't invited Xu Yuan to join our team to help, the satellite orbit design plan would not have been completed so quickly." His tone was full of gratitude and excitement.

Chen Jianfang heard these words and his eyes couldn't help but glance at Xu Yuan beside him.

He quickly thought of something and asked, "Are you saying that the plan was completed by Xiao Xu?"

And after saying this, he was basically certain that his judgment was correct.

I couldn't help but feel a little surprised about this.

He clearly remembered that Xu Yuan had only been at the Space Technology Research Institute for a few days.

It helped Gao Duo and his team solve the track design problem so quickly.

It's really surprising.

After all, before this, Gao Duo and his team had been slow to finalize the complete design plan, which could be said to be the implementation of strict standards.

What made Gao Duo so excited was that he came to him to report the matter as soon as possible.

It only shows that the solution proposed by Xu Yuan is perfect.

As he thought about this, Xu Yuan's many academic achievements in mathematics emerged in his mind.

Sure enough, there is a reason for all this.

But at this moment he was somewhat embarrassed, with a hint of embarrassment on his face.

He had previously asked Xu Chongxing for help, but Xu Chongxing recommended Xu Yuan, but he assigned him to the track design aspect. Now, he has helped a lot with the project in just a few days.

It seemed like he had gotten a great advantage.

Just as his thoughts stopped here, Gao Duo's joyful voice suddenly came to his ears again.

"Based on our orbital plan, Xu Yuan proposed a phased orbit where the satellite waits for the moon to come over and then enters the Earth-Moon transfer orbit, so as to maximize the remaining propellant."

“At the same time, it reduces the effects of weight loss and other factors caused by changes in maximum speed increments.”

"In addition, he also proposed a new idea for splicing the separately designed tracks and repeated calculations to ensure the accuracy of the tracks."

Gao Duo was not at all stingy in praising Xu Yuan, just like a parent praising his outstanding child.

As the chief designer, Chen Jianfang naturally understood the problems on the track. Just by listening to Gao Duo's words, he could feel the advantages of the phase-modulated track, which is indeed more advantageous than the traditional solution.

No wonder Gao Duo was so excited and happy, and approved the plan in such a short time.

Of course, in addition to the advantages, he can also feel the difficulties of this new idea of ​​splicing design.

Although accuracy is guaranteed through multiple calculation drills, the workload will increase a lot.

Then he reminded: "This design concept of phase-modulated track is indeed more advantageous, but you will have more work to do in terms of calculations and drills. If you don't have enough manpower, I will arrange a few more." The purpose is to ensure that the track can be put into use smoothly.

Especially during the process of the satellite entering orbit, no problems should occur.

The main thing is that the other systems of Chang'e-1 are basically determined now, so the launch can be arranged as soon as possible if the orbit is set right early.

This is related to whether the country's lunar exploration project can be carried out smoothly. It is also the third milestone after artificial satellites and manned space flight.

There must not be the slightest mistake.

When Gao Duo heard what Chen Jianfang said, he just smiled and said nothing, and then he confidently rejected the proposal.

"No need for manpower. Xu Yuan has already completed the calculations for the new track design."

"Our work will be much less later."

Gao Duo said this very calmly, as his initial shock had long since subsided.

But when Chen Jianfang heard this, his eyes widened immediately and he almost couldn't sit still.

Almost the next second, he hurriedly confirmed with Gao Duo.

"Old Gao, what did you just say? Has Xiao Xu already completed the calculation of the new track design?"

"You are not kidding me, are you?"

In any case, he found it hard to believe that such a thing could happen. It was still within an acceptable range to optimize the original plan into a phase-modulation orbit in a few days.

This shows that Xu Yuan is very sensitive to mathematics and can quickly find the numerically optimal orbital plan.

However, for a completely new track design, the workload of calculating various numerical results based on a large amount of measurement data is absolutely unimaginable.

Even if we find several people to calculate at the same time, it will probably take quite a while.

What did he hear now?
While optimizing the plan, Xu Yuan also completed the calculation of the results.

It is no exaggeration to say that with Xu Yuan's efficiency, he alone can support the track design team.

"How could I joke about such a thing? I have already obtained these partial calculation results."

Gao Duo seemed to have guessed that Chen Jianfang would behave like this, and he took out a document and handed it over.

Upon hearing this, Chen Jianfang took the document with some doubt, then opened it and looked at it carefully.

During this process, Gao Duo and Xu Yuan did not disturb him and just sat on the sofa waiting patiently.

Chen Jianfang didn't need to read all the contents. With his experience, he quickly confirmed that Gao Duo was not talking nonsense. After closing the file again, he forced himself to calm down, then looked at Xu Yuan with a warm face and asked.

"Xiao Xu."

"Have you researched this before?"

In his opinion, Xu Yuan, in addition to his amazing talent in mathematics, must have studied the content in this area before and was familiar with it, as he was able to complete the calculation with such an efficient optimization solution.

I am not like those people who only study mathematics and have no knowledge of other subjects besides mathematics.

Facing Chen Jianfang's question, Xu Yuan organized his words a little and then answered directly:

"When I was in the Department of Engineering Mechanics, I was quite interested in both aviation and aerospace."

After hearing Xu Yuan's answer, Chen Jianfang felt even more embarrassed.

Because he didn't trust Xu Yuan's level of engineering mechanics, he asked him to help in the track design team, but now it seems that there was some error in his judgment.

Maybe what Xu Chongxing said was true, Xu Yuan is indeed at a very high level in the field of engineering mechanics.

But now they are already helping in the orbital design team, and have solved the orbital solution problem so quickly. It seems a bit inappropriate to transfer them to the Chang'e-1 overall design and mass distribution research team at this time.

Although the track design team's workload has been reduced a lot, they still need to conduct multiple drills to ensure that everything goes well.

I'm afraid Gao Duo won't let him go easily.

Chen Jianfang thought of these things quickly and did not hesitate to praise Xu Yuan.

"You have such a high talent. It is a very good thing that you can make contributions to our country in other fields besides mathematics."

"If we could have more geniuses like you, we wouldn't have to worry about not being able to catch up with overseas technological developments."

"I believe that our technology will be at the top of the world sooner or later." Xu Yuan took over the conversation and said firmly.

Chen Jianfang was pleased: "You are right. We will see this day sooner or later."

After reporting the satellite orbit plan to Chen Jianfang, Xu Yuan returned to his workstation.

-

"Now that the remaining satellite orbit issues have been resolved, the lunar exploration satellite project should be completed."

Xu Yuan thought about when he first started working on orbital design, the progress bar on the panel was only 60%, which meant there was still a long way to go before the entire Chang'e-1 plan was completed.

Now that a very important satellite orbit has finally been determined, I think the progress bar should increase significantly.

In addition, according to the information he learned, the component designs of other parts of Chang'e-1 have been completed. In this case, the only thing left to complete the process is the specific manufacturing and assembly.

He muttered this to himself, and then put himself into a deep learning state.

At the same time, the familiar panel suddenly appeared in the field of vision.

-

Mission: Design and development of lunar exploration satellite

Discipline: Engineering
Progress: 60%
Result: Not completed
Xu Yuan was stunned when he saw the information on the panel: "Why is there no change in the research and development progress?"

This was very unexpected.

Satellite orbit design is an important part of the entire process, and it is impossible to complete it without making any progress. Moreover, he has completed all the calculations related to the phase modulation orbit.

Moreover, the phase modulation orbit has been verified in the previous life, so there is absolutely no possibility of error.

Thinking about the situation in his mind, he soon made a judgment.

"Could it be that there are problems with other parts of the Chang'e-1 design that prevent the progress from being made?"

Muttering to himself, Xu Yuan became more and more certain that his judgment was correct.

The entire lunar exploration satellite is composed of multiple parts. If there are problems with other design plans, even if the satellite orbit design is completed, the lunar exploration satellite's launch into orbit and detection mission cannot be successfully achieved.

We have finally solved the satellite orbit problem, but all previous efforts will be in vain if this hidden danger is not eliminated.

The key point is that if he lets it go, there is no telling how long it will take for the responsible personnel to discover and solve this problem. Thinking of this, he immediately stood up and walked towards Chen Jianfang's office again.
