Chapter 60 The Correct Method

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

For several days in a row, he went to the library to study as usual after attending small classes, but he never met Li Xiang.

Finally we met in the restaurant and found out that this guy was busy receiving confidentiality training.

He is probably taught by the same teacher as himself.

Good guy, he really became a full-time employee this time - he's already living a salary-earning life before he graduates.

Li Xiang seems to be quite satisfied with this arrangement. After all, it does not delay his studies and allows him to indulge in his addiction to bragging.

The only trouble is that in order to boast like that, his professional knowledge has to be improved as soon as possible.

Therefore, he strongly asked Chen Nian to take time to give him extra lessons, saying that his family would pay him double the market price.

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

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

"Understood, I'll look for some cases to take a look first. Thanks Chen Nian, I feel I have some direction after talking with you, so I won't be looking around like a headless fly like before."

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

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

Chen Nian asked doubtfully.

"It's the parametric design problem you mentioned. I saw a case where quadratic curve was used to solve the optimization of lift body layout, and then I felt that the quadratic curve was defective."

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

"Of course, there is also the quadratic curve method."

Chen Nian took the draft paper from him and understood it completely at a glance.

Then, as soon as he swallowed a mouthful of rice, Li Xiang sat over mysteriously.

One step closer to the goal...

"What's the problem?"

Chen Nian waved his hand, swallowed the rest of the meal in three gulps, and then turned around and went to the library.

But he was very sure that he was definitely not thinking about anything just now!

What's going on?

Wait... could it be Li Xiang?

Thinking of this, Li Xiang added:

"In the future, if I have any questions that I don't understand, just ask them for me. As long as I understand them, I can figure them out myself!"

But if I just focus on helping Li Xiang find a more efficient and accurate learning method, it won't take up too much of my energy.

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

"I just thought of it by chance... I wasn't discussing it with the spy before. Some of the things he said made sense to me - ah, I can't tell you too much."

"Otherwise, I think you already have a good foundation and are smart. In fact, you don't need extra tutoring."

In fact, as Chen Nian said, his foundation is very solid, and what he lacks most is guidance at key points - and university teachers, especially some teachers from Western Polytechnic University, to be honest

In other words, the bureaucracy is quite heavy, making it difficult for students like him to get close to him.

"Central lifting body? Why did you suddenly think of this subject?"

"About the central lifting body."

The two of them were doing their own thing quietly. Chen Nian was still learning the basics of materials science, while Li Xiang had already started to follow the path that Chen Nian had pointed out to him before, to see cases related to parametric design.

Could it be that his study is also counted on himself?

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

Chen Niannian asked without raising his head.

According to Chen Nian's considerations, one-to-one tutoring is impossible, as it would waste too much time.

"Hey, Chen Nian - no, Brother Chen, I just have a question, can you help me with my advice?"

It was really strange that Li Xiang suddenly brought up such a topic.

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

Even without the help of the system, in his previous life, like Li Xiang, he had checked some information out of interest.

The concept of central lifting body layout was only created in the third-generation aircraft era. It is relatively new compared to the other content they learn, and is not usually mentioned in classes.

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

"Chen Nian, you are my brother, so it's up to you!"

So, after thinking for a moment, he said:

"If you want to study topics related to the central lifting body, you must first understand what parameterization is. Nowadays, shape parameters are mainly realized through CAD methods. For example, NURBS curves are very typical."

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

After hearing what Li Xiang said, Chen Nian felt relieved.

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

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

"To put it simply...can I draw a key point for you?"

If this is the case, it most likely means that my previous understanding of the system rules was incomplete.

However, Chen Nian is somewhat familiar with the subject of the central lifting body.

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

It wasn't until after ten o'clock in the evening that Chen Nian got up and planned to leave. He called Li Xiang, but the latter waved his hand and said:

"Okay, let's work hard together!"

You know, the aerodynamics courses they take now are relatively basic, focusing mainly on the theoretical part, and they haven't even learned about airfoils yet.

He was concentrating on fighting with the piece of chicken on the plate that he kept biting, and he was so anxious that he could not wait to swallow it in one bite.

"Chen Nian, come and take a look!"

"Don't worry, this is just my personal interest, I don't have any other ideas."

We are all comrades within the system. If you make a mistake, it will be over if you are not caught when the time comes...

"What new idea?"

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

Under normal circumstances, the growth of source points will end when the learning action is completed. Unless you have been thinking and have some new insights, occasionally there will be a delay in settlement.

Chen Nian smiled and replied.

Chen Nian asked impatiently.

"You go first today, Chen Nian. I just happened to see the key point. I will watch it for half an hour..."

Have other ideas?

You dare.

In fact, this is not a big breakthrough. At best, it just optimizes part of the modeling algorithm, and it is not even enough to write a paper.

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

Add to this the fact that he goes to the library every day and is frequently given the standard answers to exams in class, so I believe he is definitely right.

"You have to understand these things first before you can truly understand the application method of airframe design. Only then can you think about how to design the central lifting body."

You know, he is the only student who can skip classes at will and is praised by most teachers.

"Hi, it's okay."

"The process of finding the coordinates of the end tangent intersection of a quadratic curve is too troublesome. Curves with discontinuous second-order derivatives must be processed in segments."

Is this why the system issues source points?

Seeing the obsessed look on Li Xiang's face, Chen Nian no longer disturbed him, but said goodbye and walked out of the library.

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

But this time, Li Xiang also followed.

"I'm wondering if it would be simpler if we use the agent model method to solve it."

"However, there are many issues that I don't know about when it comes to designing a central lifting body, so I would like to ask you where we should start."

"I tried it just now and it seems to work!"

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

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

As long as this "increment" is caused by yourself, you can get rewards.

Doesn’t that mean that my true direction is to be a top-level designer?

The correct working method is not to parse out all modules, but to focus on inspiring and breakthrough technologies to achieve self-circulation of the source...

Good guy, no wonder I always feel that the source point is not enough, and the relationship is about finding the right method!

Fortunately, both the engine and the body design are inspiring, and sooner or later new results will be brought back to the source, otherwise it would be a big loss...
