Chapter 14 The notebook of the top student

Back at school, Chen Nian quickly packed up his things and moved to Chen Guo's dormitory. He had already gone back to Northeast China on a business trip with other colleagues in the afternoon, and he happened to be back home with his wife and children, so the whole dormitory seemed a little empty.

Chen Guo's bedroom door was locked, but the study room was open, and there was a note he left for Chen Nian on the table:

"You can use the study room freely, and the notes on the table are for you to review. If you need any other information, you can contact the substitute teacher He Wen. In addition, there are noodles, eggs and other ingredients in the kitchen refrigerator."

Chen Nian smiled slightly, thinking to himself that the other party was really thoughtful.

Even midnight snacks were taken into account.

He tidied up the desk surface a little, then spread out the white paper and prepared to start drawing work.

According to his previous promise, he would try to submit three drawings within a week, the most complex of which was the air intake, and the simplest was the full-motion horizontal tail.

The full-motion horizontal tail is actually very intuitive in terms of structure and principle. It is even found on many model aircraft and toy aircraft. The real difficulty lies in how to integrate this set of devices into the F-22.

The integration process is actually the process of data verification and function verification.

The most important one is size.

As it happens, this point is not difficult for Chen Nian. He just needs to take out all the information recorded in his mind.

Chen Nian looked back at his notes and sighed secretly in his heart.

This can be considered learning, right?

Chen Nian turned on the system, and when he saw the source point value data, he couldn't help but feel a joyful expression on his face.

"Also, he actually felt like me that the textbook was unreasonable. From Bernoulli's equation to the potential function and flow function of the governing equations, there was no transition between these two chapters. He was confused when he was learning it."

Chen Nian sighed helplessly and read on.

In fact, he had generally been exposed to these things in his previous life, but he certainly did not understand them as deeply as he did at this time.

Yes, this notebook is indeed messy, but it is not really "messy".

According to his estimate, taking into account the advantage that duplicate parts do not require repeated drawing, it would only take about 8 more hours for him to complete all the drawings.

But he was from a high position and worked backwards from the top down.

He picked up the notebook from the table in Chen Guo's study, intending to study the experience of this national treasure-level expert who would enter the "Legendary" rank in a few years before going to bed.

However, when he opened the notebook, the contents inside really made him frown.

And the knowledge points are scattered and jumpy.

It took him about two hours from the first stroke until the final structure was roughly formed.

But as he watched, he suddenly discovered a certain pattern.

This method requires extremely high levels of talent, and it is estimated that only true geniuses can understand it.

Isn't it because that thing is more intuitive and useful than textbooks and information books?

If you can learn this "Chen Guo Notes" by yourself, will you get more source points than self-study textbooks?

Give it a try!

Chen Nian held the pen and ruler, took a deep breath, and began to draw on the paper.

This is too messy!

From the first page, it seems that the owner of this notebook has no intention of recording things in a regular manner. There is a hammer here and a stick here and there. Sometimes two sentences with a logical relationship are separated by several pages.

"The calculation of superimposed flow is much more complicated than the calculation of single type flow."

A very simple example, Chen Guo wrote about the drag calculation model on the first page, but did not record the first Cd value, which is the lift coefficient value, until 4 pages later.

Because, Chen Guo's learning method and his own learning method are actually two completely opposite extremes!

I am down-to-earth and build the foundation step by step from bottom to top.

Acquiring this is enough to take a big step forward in domestic flight control level.

Therefore, through Chen Nian's notes, he indeed gained a lot of different knowledge.

Even the F-15 can land safely on half of its wings.

The remaining work is to disassemble the more detailed parts of this part of the structure, such as rivets, bolts, bearings, etc.

In 4 hours, the number of source points increased is more than twice that of the self-study textbook.

It seems that standing on the shoulders of giants is the best solution!

Now, the number of source points he has accumulated has reached 0.09 points, and will soon break through the 0.1 mark.

It actually added 0.05 points!

So, after simply cooking some noodles for himself and taking a comfortable hot bath with free hot water, Chen Nian lay down on the bed in the guest room that Chen Guo had prepared for him.

You know, that country is a ruthless person who can make the B-2 fly.

Five hours of ultra-intensive studying and thinking even made his nerves feel tight and painful.

The reason is very simple, that is because he only really performed the verification calculation of the drag coefficient formula starting from the fourth page.

"It turns out that Bernoulli's equation can be derived using both the momentum and energy equations."

The time has already reached 11 o'clock in the evening, staying up all night is definitely not feasible.

This means that you can check it over and over again and think about it again and again!

Until you fully understand Chen Guo’s logic!

Thinking of this, Chen Nian couldn't help but get excited.

Chen Nian suddenly realized.

At least the basic understanding of the subject of aerodynamics has been substantially improved.

This may take some time, but it's no brainer.

He knew why he seemed to find it so difficult at first.

Why do everyone like to borrow notebooks from top students in high school?

It won't be long before the next analysis can be carried out.

Should we analyze the power system or the control system?

Although in the next ten years, the level of domestic avionics and control systems will far exceed that of the United States, if we can now obtain the entire control system of the F-22, especially the flight control system, the gains will be huge.

But I am not actually a genius, so it is normal for me to have difficulty understanding it.

——

However, the difficulty is only for thinking.

And now, what is presented to me is a notebook that has been formed into words.

Before that, he only used a macro perspective to understand the concept of resistance.

And when he came to his senses again, the time had directly reached 4 o'clock in the morning.

It was put together using a leaping logic.

With this idea in mind, Chen Nian quickly entered an immersive learning state.

Of course, it won't work tonight.

But the power system, including the aviation engine, is obviously also critical.

Tangled.

Chen Nian shook his head. At this time, he was feeling sleepy. He stopped thinking about it and turned over and covered himself with the quilt.

Forget it, leave this decision to the people above.

If they are confident that they can solve the material problem in a short time, then analyze the power. If not, then they should work on the control system.
Chapter completed!
