Rule department scholar

Someone lamented, "Academician Zhao will definitely get full marks no matter what level he takes the science exam." What he meant was that he did all the questions correctly, and he didn't even make a small mistake.

Others said contemptuously, "Academician Zhao is already full marks."

"That's not true. Don't you know? Academician Zhao seems to have a score of 752 in the college entrance examination?"

"Don't be kidding, the full score is only 750."

"20 points in the Mathematical Olympiad, academician Zhao is the first prize in the province, but the reason why he is only the first prize in the province is because he didn't participate in the follow-up. He was the highest score in the Mathematical Olympiad."

"That's 732? Not too high!"

"Excuse me, what is high? Can you get a full score in Chinese? At that time, I noticed Academician Zhao's grades. It seemed that mathematics, English, and comprehensive science were all short of a full score. It was almost the same as the full score. I guess it was just a poor writing process. One point deducted for each step..."

"it's a pity!"

"What's the point of this? Academician Zhao is the world's number one in mathematics. What's the big deal if you don't make mistakes in your calculations?"

"……Right!"

"Right!"

A group of people responded.

Although they all nodded their heads as if they thought it was normal, everyone was actually surprised because the design report involved too many calculations, and it was too difficult to make no mistakes.

This is much more difficult than a full score on a math test.

When they were all checking and accepting, they made mistakes in several calculations. In the end, they redesigned the calculation method, and the result was that the report was consistent, and they were all in one group, Academician Zhao...

"its not right!"

Someone suddenly asked in surprise, "There is no mistake at all, that is to say, Academician Zhao did all these calculations alone?"

"..."

"..."

Many people also realized this, and they felt very shocked at once. A large group of dozens of people, they argued and calculated for more than half a month.

How much calculation is this?

Academician Zhao alone...

"I can't imagine it!" Liu Jiankun was very surprised when he saw the report submitted by the routine acceptance team, but no matter how surprised, the result is the most important thing.

Routine acceptance, pass!

The next step is the acceptance of the 'intelligent control system'.

Liu Jiankun also immediately went to the 'Intelligent Control System' acceptance team to learn about the work progress of the acceptance team.

Then he was disappointed.

"What? Another two weeks?" Liu Jiankun was very surprised, because as early as more than a month ago, after the people from the Software Institute of the Academy of Sciences came, the acceptance team of the 'Intelligent Control System' said that there had been significant progress, and said that within a month and it will be done.

The time is long past now.

Although people from the Software Institute of the Chinese Academy of Sciences came, and academician Liu Hemin was also present in person, Guo Jinhua and Deng Minrong were the main persons in charge of the 'Intelligent Control System' acceptance team, and they were from the research institute under the Aviation Group.

Faced with the surprise and dissatisfaction on Liu Jiankun's face, Guo Jinhua and Deng Minrong looked at each other and could only smile wryly. When Academician Liu Hemin first came, he quickly figured out the situation of the core algorithm, and the acceptance progress was indeed very important, because their The main job is to understand the core algorithm. Other verifications are relatively simple, and you don’t even need to look at the source code carefully, just debug and run to see the results.

But a month later, their progress can be described as a slow speed.

The codes in those core algorithm packages involve a lot of content, and the amount of calculation is relatively huge. The most important thing is that they don't understand the principle of calculation.

In order to understand the content of the core algorithm package as soon as possible, Guo Jinhua, Deng Minrong and Liu Hemin simply worked together to communicate with each other while researching the code, but there are still a few places that are still unclear. Contact other related algorithm packages, there is no any use.

Guo Jinhua and Deng Minrong didn't know how long it would take. They could only push the time back, and maybe continue to study and discuss to find out the key points.

Liu Jiankun doesn't understand the algorithm, so he can only give it another two weeks.

soon.

Two weeks passed.

Liu Jiankun once again came to the acceptance team of the 'Intelligent Control System', but what he got was not the news that the acceptance work was completed, but...

"Let Academician Zhao come!"

"Let academician Zhao explain it in detail. We have been researching and discussing but there is no result."

"Correct."

This time Liu Hemin was also there, and he said helplessly, "There are a few points in the algorithm package that are too complicated. If you want to understand it, you need Academician Zhao himself."

Liu Hemin really let go.

In fact, he didn't want Zhao Yi to come, because he was photographed by the software to assist in the acceptance work, but he couldn't understand the key content of the core algorithm, which was really embarrassing.

However, Liu Hemin had no choice.

He, Guo Jinhua, and Deng Minrong continued to study the core algorithm, but couldn't figure out a few key points. He couldn't help but think of the 'effective and irrelevant carry selection method'.

That kind of very brain-burning algorithm requires a lot of time to understand by looking at the code. Let alone a week or two, one or two months may not be enough.

What can I do now?

In the face of the complex algorithm designed by Zhao Yi, it is nothing to lower your head a little, at least Guo Jinhua and Deng Minrong can understand, what do other people think... ahem.

This kind of acceptance work is completely confidential, and it is impossible for others, such as the Institute of Software of the Academy of Sciences, to know the process.

and so……

never mind!

Liu Hemin thought about it carefully, and immediately felt a lot more relaxed. He continued, "Manager Liu, we can't do anything in a short time. The algorithm involved is too complicated, and you know Zhao Yi's genius..."

He said shaking his head helplessly.

Liu Jiankun was indeed able to understand, but he felt very depressed at the thought of asking Zhao Yi himself to explain.

If Zhao Yi himself was to do the explanation, why would he go to the Software Institute of the Academy of Sciences?Just let Zhao Yi talk about it. The most important thing is that letting the designer himself participate in the acceptance work does not conform to the internal rules and systems of the aviation group.

Liu Jiankun knew about the problems encountered by the acceptance team of the 'Intelligent Control System', so he had no choice but to go back and think about how to solve this problem.

Finally he decided to have a meeting.

He is going to hold a group research and development meeting, specifically to talk about the design and acceptance of the Warhawk-1, and let everyone make a decision together.

soon.

Liu Jiankun released the news, asking the staff to call important personnel on the grounds of 'a major breakthrough in research and development', including not only the internal personnel of the group, but even representatives of the nearby air force.

A week later.

The aviation group's large-scale scientific research meeting began, and all the people who came to participate in the meeting were heavyweights, including two officers with the rank of 'General'.

Although it is said to be a scientific research meeting of the aviation group, it is actually a leadership-level meeting. There are only fifteen people participating, and there are only two people from the aviation group headquarters, and one is Liu Jiankun who organized the meeting.

At the very beginning of the meeting, Liu Jiankun showed the Zhanying-1 designed by Zhao Yi to the participants, introduced the routine acceptance work, and provided the theoretical performance parameters of Zhanying-1.

"Wingspan, about 12 meters, 10.5 meters after folding, about 16 meters in length, 5.2 meters in height..."

"The empty weight is about 13000 kilograms, the maximum weapon load is greater than 6500 kilograms, and the maximum take-off weight..."

"The maximum level flight speed is 1800 to 2000 kilometers per hour, and the combat radius is 1200 to 1400 kilometers."

"powerplant……"

"Support supersonic cruise, can follow the most advanced y-5cb electronic jamming device and 9c radar..."

Liu Jiankun explained in great detail, focusing on each parameter.

Many people who came here knew about Warhawk-1 for the first time, and were shocked by the design parameters. Someone couldn't help but interrupted and asked, "Are you sure you're not joking?"

"This parameter index exceeds f-35, right?"

Liu Jiankun said Zhao Yi's name, which immediately caused a burst of discussion.

After introducing the parameters and confirming that there is no problem with the conventional design, Liu Jiankun talked about the problems encountered in the acceptance of the 'intelligent control system'.

One of the 'General' leaders who participated in the meeting slapped the table and said loudly, "Is this still a problem?"

"What regulations, what systems! I don't care what regulations your aviation group has, but today you said that there is no problem with this design. I just hope to see that this aircraft can serve in the future!"

"How far is the future? The best is three years, test flight, five years, service! I am my age, and the design you mentioned today really makes my heart beat!"

"If I don't see it in service, let me tell you, I won't die with peace!"

"..."

..

Chapter 471 Liu Hemin is really not an ordinary person!

What would it be like to be slapped on the table by the "General" leader of the Air Force and yell at him, and force him to "die with peace"?

As the party involved, Liu Jiankun couldn't help but curse out the words "your ringgit".

Of course.

He considers himself a cultural person of the new era, never speaks dirty words, and still doesn't care about the leaders at the 'general' level, but he still feels very depressed after being yelled at twice.

Of course, he is also optimistic about the design of the Warhawk-1. Just talking about the design of the regular part of the Warhawk-1 is already very distinctive. Refer to introduce some methods.

However, the internal rules and regulations of the aviation group are also very important. For the entire group, the rules and regulations are like the laws of a country. How can they be easily violated?

It is possible to do something special, provided that a large group of people agree.

Now it's time to ask for everyone's consent.

The air force general Peng Hongguo who just patted the table to express his opinion is close to the age of retirement. Not only has his military rank reached the top, but he also has great power in his hands.

As one of the important figures in the military, Peng Hongguo's attitude can even affect the development of the air force. He has a certain decision-making power when the military decides to purchase a certain type of fighter.

Not to mention political influence, this kind of person is a customer of the aviation group in a certain way.

Customers are God!

"Yes, the customer is God, what's wrong with God losing his temper? And it's just to express his attitude..."

Liu Jiankun quickly convinced himself, and immediately said with a stiff smile, "General Peng, of course we also know that this design is good, so we have today's meeting."

"I haven't finished my introduction just now." What he meant was that the introduction was not complete, and the real things have not been said yet, so the expression of attitude can be postponed for a while.

"I don't know what the design is, anyway, I have spotted this fighter." Peng Hongguo nodded and sat down after speaking.

Liu Jiankun continued to explain.

He only briefly talked about the theoretical parameters of the Zhanying-1 design. In fact, many parameters are not determined by the design, but by the theoretical performance of the engine.

For example, combat radius, maximum speed, load capacity, etc. are all directly related to engine performance. As long as there is a top-level engine, similar performance parameters will not be bad.

These parameters are very common, and what is directly related to fighter jet design is flexibility, and the outstanding point of the Warhawk-1 design is also the ultra-high flexibility brought about by the variable component design.

There is an important indicator of flexibility called 'overload', which can be understood as the maximum force exceeding its own weight, and the maximum force is the same as its own weight, which is the unit of 'overload', expressed in G.

For example, if a person weighs 100kg and receives a force of 100g, then the overload is 1G.

When a fighter jet is flying at high speed, if it turns suddenly at a large angle, an 'overload' situation will occur. It is conceivable that a car traveling at high speed suddenly changes direction drastically, and the huge inertia will make the car bear a huge load. Generally speaking, for fighter jets with high flexibility, the maximum overload design does not exceed 10G, that is, the fighter jet can only make movements of up to 10G.

The main consideration of this design is stability. When the overload exceeds 10G, the fighter may face the risk of disintegration.

Also, consider the pilot as well.

The pilot in a fighter jet is with the aircraft, and the overload that the pilot can withstand is about 5 to 7 G. Some pilots have a relatively strong tolerance, and the maximum overload cannot exceed 10 G.

The prominent point of the Warhawk-1 design is here, because a large number of changeable design parts can make the action process of the fighter plane more smooth when there is a major change, which makes the original '10G' overload action truly reflected on the aircraft itself Only with '8G', the fighter's ability to withstand 'overload' maneuvers is greatly enhanced.

It is very rare that it is urgent enough to withstand the 10G overload action. During normal flight and combat, the overload exceeds 2G or 3G.

For example, accelerating takeoff and decelerating landing.

The limitation of most fighter jets to accelerate takeoff and decelerate to fall is not entirely due to the performance of the engine, but also includes the fact that the acceleration (deceleration) speed is too fast and the pilot's body cannot bear it, so the acceleration (deceleration) speed must be limited. The Warhawk-1 The unique design will allow the same acceleration, the fighter and the pilot will bear less overload, and the direction of change will not be stiff, but very gentle.

"If you can have a cabin with better shock absorption, the overload buffer can continue to be improved." Liu Jiankun said with certainty.

Next, he began to introduce the flexibility. For example, the Warhawk-1 can support ultra-low-altitude accelerated flight, and can even fly close to the sea level. Because the flexible design is very advantageous, the Warhawk-1 can adapt to operations in various environments.

"It's pretty much omnipotent."

Liu Jiankun summed it up in one word, "This design allows it to adapt to various tasks."

Liu Jiankun's explanation made the participants even more excited. When they heard the common parameters just now, they already thought it was amazing. The result parameters are just the beginning. The most outstanding thing is flexibility, which can be understood after thinking about it. If the performance of the corresponding parameters is exerted, there is no need to design the folding wing at all.

Some people who are familiar with fighter jets feel that the design has reached the top level, and it has reached the point where there is no room for improvement.

In terms of fighter jet design, it can be said that there is no room for improvement. If a fighter jet wants to improve its performance, it needs not design but equipment, and other technologies.
