On the other hand, after all the data at hand was handed over and Li Xiang's affairs were dealt with, Chen Nian returned to his regular study life.

For several days, he went to the library to study according to the usual practice after attending a small class, but he never met Li Xiang.

I finally met in the restaurant, and I realized that this kid was busy receiving confidentiality training.

It is estimated that he still teaches him the same teacher as himself.

Good guy, this time he really turned positive---- he hasn't graduated yet, and he has already lived a salary.

Li Xiang also seems to be quite satisfied with this arrangement, after all, it does not delay his study, and he can also live the addiction of bragging.

The only trouble is that to brag about it like that, his expertise has to be improved as soon as possible.

Therefore, he strongly asked Chen Nian to take time to make up for him, saying that he would let his family pay his salary, and the market price would be doubled.

This request was naturally rejected by Chen Nian---- he couldn't arrange his own time, how could it be spent on him.

However, looking at Li Xiang's slightly disappointed expression, he still proposed an alternative.

"Otherwise, I don't think you're bad in the first place, and you're smart, so you don't need extra make-up classes."

"However, you may need some guidance in key directions, and I can help you with this."

"To put it simply...... Can I draw you a highlight? ”

According to Chen Nian's consideration, one-on-one make-up lessons are impossible, which is too time-consuming.

But if you just focus on it and help Li Xiang find a more efficient and accurate study method, it won't take up too much of his energy.

Hearing Chen Nian's words, Li Xiang was overjoyed.

"Chen Nian, you are my brother, then it depends on you!"

In fact, as Chen Nian said, his foundation is very solid, but what he lacks the most is guidance at key nodes---- and the teachers of the university, especially some teachers of the Western University of Technology, to be honest, are more bureaucratic, and it is difficult for students like him to approach.

Therefore, there is no way to make up for this piece.

But now that Chen Nian is here, there is no need to worry.

You know, he is the only student who can skip class casually and is praised by most teachers.

Coupled with the fact that he goes to the library every day and is taken out as a standard answer at every turn, I believe he must be right.

Thinking of this, Li Xiang added:

"In the future, if I have any questions that I don't understand, you can help me mention them, as long as I get through the key, I can understand it myself!"

"Okay, let's work together!"

Chen Nian replied with a smile.

Then, as soon as he swallowed a mouthful of food, Li Xiang sat down mysteriously.

"Hey, Chen Nian---- it's not right, Brother Chen, I just have a question, can you help me with the staff?"

"What's the problem?"

Chen Nian asked without raising his head.

He was intently wrestling with a piece of chicken on his plate, and he was so anxious to swallow it.

"About the central lifting body."

"Central lift body? How did you suddenly come up with this topic? ”

Chen Nian asked suspiciously.

You know, the aerodynamics courses they learn are still relatively basic, mainly focusing on the theoretical part, and they haven't even learned the airfoil yet.

The concept of central lift body layout was only produced in the era of third-generation aircraft, and it is still relatively new compared to the other content they have learned, and it is generally not mentioned in class.

It was really strange for Li Xiang to suddenly bring up such a topic.

Hearing Chen Nian's question, Li Xiang smiled embarrassedly and replied:

"It just came to me by chance...... Didn't I discuss it with the spy before, but I think some of the things he said make sense---- I can't tell you too much. ”

"In short, I recently read some information, and I think that the layout of the central lifting body is actually quite promising, and under the premise that the engine performance cannot be improved, the use of the central lifting body layout can greatly improve the maneuverability."

"However, there are a lot of questions that I don't know about when it comes to the design of the central lifting body, so I would like to ask you what direction you should start."

"Don't worry, I'm just a personal interest, I don't have anything else in mind."

Hearing Li Xiang's words, Chen Nian relieved himself.

Have another idea?

How dare you.

They are all comrades in the system, and if you make a mistake and see that you can't catch it when you see it, you will be finished......

However, Chen Nian is really a little familiar with the topic of the central lifting body.

Even if he didn't use the system, in his previous life, like Li Xiang, he checked some information out of interest.

So, after thinking for a moment, he spoke:

"If you want to study a topic related to the central lifting body, you must first understand what parameterization is, and now the shape parameters are mainly realized by CAD methods, such as NURBS curves."

"Of course, there are also those that use the quadratic curve method."

"You have to understand these things before you can really understand the application method of body design, and then you can think about how to design the central lifting body."

"Because the aerodynamic optimization involved in the central lifting body is more complex than the conventional layout, there is a lot more to learn......

After listening to Chen Nian's words, Li Xiang nodded solemnly.

"Understood, I'll go find some cases first. Thank you Chen Nian, I feel a little bit of direction when I talk to you, so I won't look around like a headless fly like before. ”

"Hey, it's okay."

Chen Nian waved his hand, swallowed the rest of the meal three times and divided it by two, and then turned around and went to the library.

And this time, Li Xiang also followed.

The two were quietly doing their own things, Chen Nian was still learning the basics of materials science, while Li Xiang had already begun to follow the path that Chen Nian had shown him before, and went to see cases related to parametric design.

Until the evening until ten o'clock in the evening, Chen Nian got up and was about to leave, he called Li Xiang, but the latter waved his hand and said:

"Today, you go first, Chen Nian, I just saw the key point, and I will watch it for half an hour......"

Seeing Li Xiang's indulged look, Chen Nian no longer bothered him, but walked out of the library by himself after saying goodbye.

On the way to his residence, Chen Nian opened the system interface, and judging from the display on the interface, the number of his source points has accumulated to 0.46 points.

One step closer to the goal......

Chen Nian smiled with satisfaction, and was about to turn off the interface, but at this moment, the number "0.46" suddenly jumped, and instantly became 0.47!

What's going on? Does walking count as studying?

Normally, the growth of the source point will end at the end of the learning action, unless you have been thinking about it and have produced some new understanding, and occasionally there will be a delay in settlement.

But he's pretty sure he didn't think about anything just now!

What's going on?

Wait a minute...... Could it be Li Xiang?

Could it be that his learning is also counted on his own head?

Chen Nian did not hesitate, turned his head and returned to the library, and Li Xiang in the seat stood up excitedly as soon as he saw Chen Nian.

"Hey, Chen Nian, come here, I just had a new idea, and I was about to ask you, but you actually came back......"

"What's new?"

Chen Nian asked impatiently.

"That's the parametric design problem you mentioned, I looked at a case of using a quadratic curve to solve the layout optimization of a lift body, and then I felt that this quadratic curve was flawed."

"The process of solving the coordinates of the intersection of the end tangent of the quadratic curve is too troublesome, and the curve with discontinuous second derivative has to be processed in segments."

"I'm wondering if it would be easier to solve the problem with a surrogate model."

"I tried it just now, and it seems to be really feasible!"

"Chen Nian, come and take a look!"

Chen Nian took his scratch paper, and at a glance, he completely understood.

This is actually not a big breakthrough, at best it only optimizes part of the modeling algorithm, and it is not even enough to write a paper.

However, if we continue to diverge from this method, in the future, when computer technology is fully developed, and then introduce new tools such as genetic algorithms and machine learning, this small optimization potential can be realized.

Is this the reason why the system issues the source point?

Chen Nian's heart moved, and he vaguely realized something.

If this is the case, it probably means that your previous understanding of the rules of the system is incomplete.

The so-called source point does not come from the learning process, but from the "knowledge increment".

As long as this "increment" is self-initiated, you can get a reward.

Doesn't that mean that his real direction is actually a top-level designer?

The right way to work is not to parse all the modules, but to focus on inspiring, breakthrough technologies that enable self-circulation at the source......

Good guy, no wonder I always feel that the source point is not enough to spend, and the emotion is not the right way!

Fortunately, both the engine and the airframe design are inspiring, and sooner or later they will lead to new achievements to bring back to the source, otherwise it would be a big loss.......
