"In my opinion, it is normal for a certain stock to rise by dozens of points within a period of time, with several daily limits, right? The market value of Hongfeng Industry has increased by more than 100 billion, but it has nothing to do with me. I own There are still so many shares, as long as you don’t sell them, you can’t make money.”

"Many securities experts say that value investing is still necessary, and I agree with them. The difference is..."

"I think Hongfeng Industry has investment value, so I invest, it's as simple as that. They think it has no value, but I think it has value. The difference is here. As for the profit rate of the analysis, etc., I don't know much about it, but I think, I think, investing is a long-term thing, and I think the future has value, not the present.”

"I would like to remind all investors here that investment must be calm and prudent, and you must have your own judgment, and don't follow others..."

Zhao Yi said a lot in the interview, mostly to express his own attitude, and he also reminded investors in the middle of the interview that investment needs to be more calm, and it is irrational to follow the trend of investment.

that's enough.

That's all he can say.

If you continue to talk about guiding investment, it may be considered as "violating the regulations" by the securities management department, and you may face problems such as market entry ban.

Therefore, when it comes to investment, public figures still need to be stricter in their tone of voice, and don't say what you can't say.

After Zhao Yi accepted the interview, he stopped paying attention to public opinion, and instead devoted himself to the design and development of the aircraft. Two months later, the design of Zhanying-1 has also made great progress.

The urging of years ago is still effective.

The research and development organization related to the Warhawk-1 design has significantly improved its work efficiency. The technicians who should be dispatched two months later arrived. They came here to connect with the Warhawk special research team and explain the equipment-related requirements in detail.

The power engineering laboratory has also become much more lively, with many professionals coming and going, making the mechanical laboratory building look like a busy company.

The War Eagle special research team actually only has three people, Zhao Yi, Lei Yong and Bao Enhong.

Lei Yong and Bao Enhong became very busy. They took on the role of data docking company with the technical personnel of relevant institutions, and fully understood the needs of various equipment and the impact of installation on aircraft design.

Afterwards, they will submit detailed reports to Zhao Yi, and Zhao Yi will read these reports to determine how to refine and correct the overall design of the aircraft.

The refinement and correction of aircraft design is very simple for Zhao Yi. Generally, after some research, the results will come out directly. He also found that there are professionals who can do the handover work in advance. It will become a direct 'design question' instead of discussing additional requirements and the like.

In some cases, even the learning currency is not consumed, it is just a simple modification of the design, and the result will come out immediately.

Zhao Yi's work focuses on the electronic control system that regulates the shape and components.

The key point of the design of the Warhawk-1 is that many automatic control parts have been added to the shape and components. The focus is on the wings and tail. The wings and tail are somewhat general. Many components of the wings and tail are run alone.

For example, trailing edge flaps.

Trailing edge flaps are airfoils that deflect downward as needed to increase lift during flight.

The design of Warhawk-1 is to allow the trailing edge flap to automatically change direction when the altitude is stable, so that it is parallel to the direction of the fuselage as a whole to reduce the resistance during flight.

The corresponding leading edge flaps are also similar.

The aileron is one of the main control surfaces of the aircraft. Through the differential movement of the ailerons on both sides, the aircraft can produce a rolling effect, but it is useless in normal times. It can also be retracted when not in use.

Other components such as vertical fins, rudders, dorsal fins, lowered landing gear, built-in magazines, etc., can be automatically adjusted according to the flight status, so that the aircraft is always in the "best state" for the aircraft situation and flight needs.

This requires a very powerful electronic control system for coordination.

In fact.

The electronic control system for the automatic overall adjustment of fighter jets is very high-end in the world. Even the most advanced fighter jets in country M only have simple adjustment functions, and some adjustments require manual operation by the pilot.

The overall automatic adjustment is very intelligent.

The main difficulty of this technology is that the pilot's operating intention must be clearly captured by the aircraft's main control system, which involves the cockpit operation room, the sensing ability of manual control parts related operations, and the fine sensing control ability.

The sensor is not the problem, the key lies in the internal analysis of the control system.

Zhao Yi quickly completed the framework of the main control system, and later found that the most important thing is the analysis algorithm. How to 'calculate' the most likely intention of the pilot based on the data obtained by the sensors is the key to the main control system.

Of course, there is a simpler method, which is to design several fixed modes for the aircraft, and let the aircraft directly change the corresponding modes, but the change of the direct mode will make the adjustment process of the aircraft too rigid, and it will also be different from the various aspects of the shape design. No, there is a conflict in the function of automatic adjustment according to the wind force and wind direction.

Therefore, three modes must be designed, one is the intelligent automatic control system, and everything is calculated by the system to make the pilot's operation easier.

One is the form of embedded mode, which fixes several most commonly used modes.

The last is the emergency manual control mode.

When there is a problem with the control system, or in a very extreme situation, the pilot can choose to enter the manual control mode and fix the positions of several parts of the shape to deal with it.

If you want to maximize the performance of the Warhawk-1, you still have to rely on the intelligent control system.

Zhao Yi has been working on intelligent control systems for a long time. He has a feeling of returning to his "old profession". His initial achievements are in computer algorithms. The new intelligent algorithm is still very interesting because of the difficulty of the algorithm. Quite high, even no less than solving the world's mathematical problems.

However, Zhao Yi's research and development life is relatively easy, because he can't get nervous, and the biggest limitation comes from the learning currency. When the learning currency is basically used up, he always accumulates a little daily currency, and then finds time to do something useful. Algorithmic research of difficulty.

Although in Zhao Yi's view, the development speed of the intelligent control system is very slow, in fact, compared to his own speed, the completion time is not slow.

About three months later, he still completed all the codes, and used the "Supervisory Law" for testing, and also debugged and ran it, and found that there were no problems before it could end.

at the same time.

People in the War Eagle Special Research Team, and even the War Eagle Team, including Yuan Haitao, Zhou Qing and others, because they have worked with Zhao Yi for a long time, they also know exactly what he is doing.

They are laymen do not understand.

Lei Yong and Bao Enhong have a little understanding. They know exactly what Zhao Yi is doing, and they have confidence in Zhao Yi's ability level. long time.

When they talked about it in private, Lei Yong said, "I originally thought that I would only work for a few months at most when I joined the Eagles team, but now it is estimated that it will take two or three years."

"Academician Zhao developed this kind of system by himself. I don't know how long it will take. The good news is that we will be free in the future, and we should just wait. Sitting here and getting paid for nothing..."

Bao Enhong said, "I'm not in a hurry. I was prepared when I came here, and I may have to work for several years or ten years. But Academician Zhao is really good. The design is too high-end, and we can't help at all. I think Zhao Academicians should consider recruiting a few professional information engineers to develop together.”

"Yes."

Lei Yong nodded in agreement, "We still need to find a professional in this area. In terms of the difficulty of research and development, it is estimated that we need to find the top informatics experts, algorithm experts or software engineers."

While the two were talking, they noticed that the door of the office opened.

Zhao Yi came out from inside with a smile on his face, he still held a cup of coffee in his hand, and said with a smile, "It's done."

He sat down and told Lei Yong and Bao Enhong, "You can start writing the design report. I will write the report on the intelligent control system. You mainly write the design analysis report."

"It's just like the design report that was given to me at the beginning, analyzing the function of each part, design principles, data arguments, etc..."

Zhao Yi explained a lot in succession.

The design report is still very important. Only when there is a design report can it be submitted. Applying for design acceptance, it is no problem for him to do the design himself. It is a bit difficult to write the design report, because he does not understand the principles of many designs.

Anyway... just perfect!

Lei Yong and Bao Enhong are more professional, they can analyze and deduce something from a design.

Of course.

For some things that involve the calculation of specific design data, Zhao Yi still needs to come in person, but most of the routine content can be handed over to the two of them.

Lei Yong and Bao Enhong were both stunned.

They were still discussing the 'working hours issue' just now, how could it be done all of a sudden?

After Zhao Yi finished speaking in one breath, Lei Yong said in surprise, "Academician Zhao, you mean that the intelligent control system...is completed?"

"Yup?"

Zhao Yi frowned, "Is that what I said at the beginning?" He looked at Lei Yong, as if looking at a bad student who 'doesn't listen to class'.

Lei Yong smiled wryly and Bao Enhong looked at each other, their eyes were still full of shock.

But they could only be shocked.

Zhao Yi will not explain in detail why it can be completed quickly, he just came to explain the next work to the two, but he hopes that the design will be accepted sooner.

The design and acceptance work of Warhawk-1 is not only related to the manufacture of the prototype, but also related to "obtaining a large amount of learning coins".

In recent months, Zhao Yi has been troubled by the "moonlight of learning coins". Every time he does research and development, he is also limited by the number of learning coins. ' time.

Then the three of them began to write reports seriously.

A week later.

Zhao Yi checked the reports of Lei Yong and Bao Enhong, only carefully looked at the data problem, and did not even modify it, so he directly approved it, put it together with his own report, and wrote a Zhanying-1 design completed, application The superior department makes an acceptance report.

Lei Yong was surprised that Zhao Yi directly approved their report without even revising it.

He asked remindingly, "Academician Zhao, don't take a closer look, can you correct it?"

"Need not."

Zhao Yi understood Lei Yong's meaning, "I have confidence in the design work. As for the report, it is a simple explanation. As long as the design and data are fine, it doesn't matter if there is a deviation in the explanation."

"Anyway, when the group checks and accepts, it must repeatedly demonstrate the design of each part. What does it matter if our report is well written?"

Lei Yong was right when he thought about it.

but……

After the design project is completed, submit the design acceptance report, and don't even bother to read it carefully. It seems a bit too perfunctory, right?

At the same time, Lei Yong couldn't help but sigh in his heart, "Academician Zhao is Academician Zhao!"

"What leadership does not lead. Anyway, when the acceptance report is submitted, the group will definitely send an expert group to check and accept it. It is completely pragmatism, and it is really a spirit worth learning!"

"but……"

"Others can't learn it even if they want to!"

Chapter 465 Li Jianming: What is the value of my design?

Aviation Group Headquarters.

Liu Jiankun is receiving visitors in his office. It is Yang Cong, a designer of Shencheng Aircraft Research Institute.

Yang Cong is a well-known aircraft designer in China. The famous H-6 bomber was written by him. The fighter series has also designed the J-11B with reference to the Soviet fighter. Recently, he is working hard on the design and revision of the J-15 carrier-based aircraft. .

The J-15 incorporates the technology of the J-11B. The problem of catapult take-off was considered at the beginning of the design. It will be loaded on a domestic aircraft carrier in the future. As early as more than two years ago, the J-15 completed its first test flight.

However, the test flight of the first aircraft after assembly does not mean success. The test flight is still only experimental in nature, and the design will continue to be adjusted according to the effect of the test flight.

Yang Cong is doing this work.

As a well-known aircraft designer in China, and has been working hard to revise the design, Yang Cong is well aware of the difficulty of fighter design. Compared with heavy bomber fighters, fighters need to be very flexible and constantly expand their combat capabilities. is to have a more comprehensive ability.

Such as air, ground, signal warfare and so on.

Only with these capabilities can a fighter plane become an independent combat unit, and the purpose of using a fighter plane is the same. Every fighter plane can be said to be an independent air combat unit. Because of factors such as the combat environment and combat needs, other combat departments Can't give much support either.

The higher the demand, the more complex the design.

The J-15 carrier-based aircraft designed by Yang Cong refers to the data of a large number of fighters. In addition to the J-11B, which is similar to the fighters of the Soviet Union, it also includes a T-10-K-3 obtained from Ukraine at the beginning of the century. , The design schemes of several fighter planes are clear in the chest, and only then can the schemes be revised little by little.

Now that Yang Cong is looking for Liu Jiankun, he also needs the support of the aviation group to invest more funds in the design modification experiment. He has two positions where the design is not sure, so he needs to build the fighter according to the design and test the flight to see the data.

This process will definitely consume a lot of money, a lot of manpower and material resources, and at the same time there are certain risks.

So Yang Cong had to get the support of Liu Jiankun.

Liu Jiankun was listening to Yang Cong talking about design issues, and nodded frequently as if to agree with his statement, but he was still a little unsure, because it would cost more than 3000 million yuan to experiment with the design, and 3000 million yuan sounds like a lot of money. Not much, but just for a small scheme in the experimental design, it needs to be carefully considered.

But Liu Jiankun did not directly refuse. He needs to listen to everything patiently before he can make a decision with others.

When the two were talking, the assistant knocked on the door suddenly, stood at the door and looked over, "Mr. Liu, excuse me."

"what happened?"

Liu Jiankun said impatiently, "Didn't you see that I am talking with Professor Yang?"

The assistant hesitated for a moment, then walked in and whispered, "The following has received an application for design acceptance."

"What acceptance application?"

"Academician Zhao's."

"Academician Zhao?" Liu Jiankun repeated, then frowned and asked, "Academician Zhao Yi?"

"Correct."

The assistant nodded and said, "Sent by Academician Zhao, the design of Zhanying-1 is applied for acceptance by the group."

"..."

Liu Jiankun opened his mouth slightly and did not close it. He was stunned for a long time before he asked with certainty, "Academician Zhao Yi? Design of Zhanying-1? Zhanying-1? Did you hear me right?"

The assistant was a little helpless, "I have repeatedly confirmed it several times."

Liu Jiankun took a deep breath and nodded, "How about this, you ask them to send the application report directly to my mailbox, and then print a copy and bind it, and it happens that Professor Yang is here..." He said and looked at Yang Cong.

Yang Cong's face was also full of surprise.

When the assistant left to explain the matter of sending emails and printing, he couldn't help asking, "Academician Zhao's Eagle Team? I knew they were designing fighter jets, but I didn't expect it to be so soon..."

As he spoke, he suddenly let out a breath, and then his expression became a little funny, "Our institute, Lei Yong, is an excellent designer, and he took the initiative to apply to go to Academician Zhao."
