From small town scholar to chief scientist

Chapter 314 Shock Absorbing Device
At present, as long as the development of aviation power is discussed, jet engines are still inseparable.
The potential of the traditional turbofan engine is almost exhausted.

It is nothing more than using more high-temperature-resistant lightweight materials. Therefore, the adaptive variable-cycle engine is expected to be high.

The brand-new engine is closely related to the application of mathematical models, algorithms and artificial intelligence.

While the adaptive variable cycle engine is under the same amount of fuel,

The airborne time of combat aircraft can be increased by 50%, the maximum range will also be increased by 33%, the fuel consumption rate of the engine will be reduced by 25%, and the fuel heat absorption rate will reach 60%.

Therefore, the adaptive variable cycle engine is the core of the sixth-generation fighter.

By then, the maximum range may reach 8000 kilometers with only the fuel in the aircraft.

The distance of 8000KM, one can imagine how far away it is.

The southernmost and northernmost Douji in Daxia Kingdom can fly back and forth,
It is also possible to fly back and forth between the westernmost and easternmost of the Great Xia Kingdom.

The speed is faster than before, the bomb load is higher, and it is more intelligent.

With the operation of the intelligent system, the drone can even fly so far.

This is the sixth-generation fighter with artificial intelligence.

If a war breaks out, it is enough to let the swarms of sixth-generation fighter jets be unmanned.

Remote voice control, almost zero delay and precise instruction,
Not only that, but also reduce pilot casualties.

When heavy helicopters get a major breakthrough, there will be no unexpected disasters at that time,

The materials can be directly delivered by unmanned driving, which is convenient and fast, and reduces the potential risk of personnel.

The variable cycle aeroengine is a complex multivariable nonlinear system with dozens of control variables, which makes the design of its control system very complicated.

Model-based direct performance control method is the development direction of aeroengine control system design,
The key issues to be solved are the quantification of engine health parameters and the acquisition of performance parameters such as thrust and surge margin that cannot be directly measured by sensors.

Therefore, it is of great significance to carry out research on estimation methods of unmeasured parameters of variable cycle engines for the development of advanced model-based control methods for aeroengines.

This is the 6G technology and the first-generation artificial intelligence technology that Zhouyi spent a lot of time and energy building.

With the help of artificial intelligence, a lot of time costs can be reduced.

Academician Ma from the office said:
"Professor Zhou, according to the previous idea, do an augmented model reference adaptive sliding mode control method based on the LQR method,

Next, we augment the model and design a reference model by adopting the optimal LQR method to provide a reference state to the controller. "

Zhou Yi listened, without interrupting Academician Ma's speech,

This idea is correct, and it is used in the research of variable cycle engine model adaptive sliding mode control method.

The theories, experiments, and equipment needed to develop a super engine are unimaginable.

You can only eat one bite at a time, and it is impossible to become a big fat man all at once.

Zhou Yi watched Academician Ma stop speaking, and said:
"Is there no idea behind?"

Without any hesitation, Academician Ma said directly:

"That's true, we struggled with whether the theoretical approach we adopted was Lyapunov functions or something else."

Zhou Yi said:

"In fact, this direction is correct, that is, to use the Lyapunov function."

Zhou Yi said while writing something on the whiteboard.

"Based on the state-following sliding-mode control method based on Lyapunov functions,

The adaptive law of the upper bound estimation of the perturbation matrix and the upper bound estimation of the external disturbance can be deduced under strict stable conditions.

Next, the controller can achieve the goal that the tracking error of the system is asymptotically zero under the conditions of uncertainty and external disturbance. "

Some words on the whiteboard and the words in Zhou Yi's mouth made their thoughts suddenly clear.
What was once an indecisive thought has now become a definite one.

According to the past, without Zhou Yi's help and guidance, they might try one by one,

In this way, the cost of time and money spent will be unimaginably high.

Now with the help of Zhouyi, the advantage is that it can save time, cost and money.
Overtake Ugly in a short time,

You must know that Ugly has continued to carry out a number of variable cycle engine research projects in adaptive variable cycle engines, and developed two variable cycle engines, F120 and F136.

The only disadvantage of this is that it is impossible to train the level of scientific researchers,
I haven't experienced the trials one by one, and the speed of level increase is not as fast as imagined.

But it doesn't matter, because Zhou Yi controls the overall situation,

They are responsible for doing things for Zhou Yi.

Otherwise, they wouldn't have come here from Shenfei, Shufei, and Xigong University.

To hug your thighs, you must have the awareness to hug your thighs.

Not long after, everyone got Zhou Yi's approval and left.

Zhou Yi washed his face in the office, cleared his head, and then devoted himself to the next job.

The development of the sixth-generation engine is a long-term project with a weak foundation.

Even if it cooperates with countries such as Enfad and Tsarist Russia,
Nor can it be digested in a short time.

This is also the reason why they made up their minds to form an alliance with Great Xia.

No country will reject sixth-generation fighter jets.

With a range of 8000KM, fighter jets can directly cross the Atlantic Ocean.

What this means is self-evident.

What's more, there are such things as Zhou Yi Huabing's space-based weapons and space carriers.

At present, it seems that Zhou Yi has achieved a great lead in some fields,
In fact, the Ugly country is unique in the world in the field of fighter jets.

Two types of variable cycle engines have been produced. If Zhou Yi hadn't led Academician Ma and others to do it,

The country is basically at the stage of exploration.

Ugly country put forward the theory of variable cycle engine in the last century,

From the 20s to the 60s, a variety of variable cycle engines were being developed.

However, in the 20s, variable cycle engines gradually evolved from a number of research and development companies to GE alone.

GE developed the YF21 engine on the basis of DBE-GE23 and DBE-GE120, which is the world's first flight-proven double-duct variable-cycle engine.
However, due to the failure to compete with the F119 engine, it did not enter the engineering development.

Ugly country is a sword, not a dish.

Zhou Yi never underestimated them.

We all know the disparity here, sometimes it will be very hopeless if you look directly at it.
But the Great Xia Kingdom took one step at a time, abruptly changing from the despair at the beginning to the hope that they can keep pace with each other now.

This is the charm of the Great Xia nation, and this spirit of never giving up is also what Zhou Yi is proud of and practices.

As for those who flattered foreigners back then, now they can only deeply regret it.

Similar to chatGPT, it was the first time that Ugly Country came up with it, and only opened the GPT3 interface to the outside world.

Although it is more open now.

In many fields, the background accumulated by Ugly Country is beyond doubt.

However, Zhou Yi is also leading people to surpass them, at least now many technologies have surpassed them.

Zhou Yi is seriously studying the BSD conjecture in the office.

The BSD conjecture is the Millennium Prize problem, also known as the world's seven major mathematical problems, a mathematical conjecture announced by the Clay Mathematics Institute (CMI) in May 2000.

B and SD are the initials of the last names of two mathematicians,

The full name is the Birch and Swinnerton-Dyer Conjecture (Birch and Swinnerton-Dyer Conjecture), which is a famous problem in the field of number theory.

Its essence is to describe the set size of a certain special indeterminate equation (elliptic curve),
The BSD conjecture gives two different indicators—algebraic rank and analytic rank—through two completely different ideas, and conjectures that they are equal.

Although the conjecture is difficult and obscure, it is in line with some knowledge of number theory that has been passed down for thousands of years in textbooks.
It is a further exploration of ancient problems by the seekers of truth since entering the modern society.

For the research on this conjecture, the Chinese Academy of Sciences, Daoguo and Yingguo have done the best research.

The former has sprung up in recent years and has made great efforts.

The latter two are mathematical powers with historical background,
Goro Shimura, Davenport, Wiles, and Wiles' teachers all had a deep understanding of this problem.

Fortunately, these old guys are old, otherwise, with the advent of Zhou's analytical method, they might really solve this problem completely within a few years.

Number theory really depends on age and talent, Zhang Yitang was an exception that day.

There are really very few people who are getting older and fiercer.

The difficulty of BSD conjecture is far beyond Zhou Yi's imagination.

After watching it all afternoon, Zhou Yi looked at several apprentices with dizzy eyes and couldn't help but think of something.
Zhang Jiahui and Jiang Guoyu both graduated, can't they submit their apprenticeship tasks again?

I was so busy that I forgot about it.

Of the eight students who graduated from the division, 4 are studying artificial intelligence.

4 have not rebelled yet, and continue to work in the field of mathematics.

Thinking of this, Zhou Yi chanted directly to the system.

"Submit task three, apprenticeship task."

With two students as teachers, now Zhou Yi is only two students away from completing this task completely.

The Book of Changes actually doesn't want to end. If you bring your apprentices, you can gain mathematics experience.
That was just so cool.

Not long after, the system's cold voice sounded in Zhou Yi's ear:

【Ding.Among the two student mathematics papers identified,
良！
Ding, congratulations to the host for obtaining 10 math experience, 2000 points, and 6 lucky draw chances. 】

[Host: Zhou Yi.

Mathematics: LV6, 77/100W; (Mathematics level reaches LV6, you are about to reach the highest level of mathematics on this planet)
Points: 16634, chance of lucky draw *18. 】

You can reach level 23 with 7 math experience.
Zhou Yi thought of this, and the research on the BSD conjecture and the NS conjecture became more vigorous.

Mathematics LV7 is definitely the top group of mathematicians in the world.

He kept pace with Mirno, Qiu Chengtong, Deligne and others, and even surpassed them.

Two millennium puzzles, plus previous number theory conjectures,

Enough to be the top mathematician in the world.

And a mathematician in all fields.

While Zhou Yi and Xia Xue were having dinner in the cafeteria,
Wang Yifang brought a group of professors from the School of Physics to Zhou Yi.

Zhou Yi looked at them and said:
"What's the matter?"

"Xiao Huang, serve a cup of scented tea to all the professors."

Huang Shunjian immediately poured tea for the professors.

Wang Yifang's expression was a little dignified, and she said:
"Professor Zhou, we have installed the CEPC anti-seismic device, but we have many ways to absorb seismic waves.

Some of them are quite feasible and have specific applications in many countries and regions.

We have also developed a shock-absorbing energy-absorbing device, which is a systematic modeling method for seismic wave absorption and attenuation from the perspective of mathematics and mechanics.
According to the established attenuation model, a compensation method for absorption attenuation based on seismic inversion and imaging is proposed. "

Zhou Yi heard this and said:

"So now is it necessary to make a breakthrough in the mathematical theory, or do I need to do the knowledge in physics?"

Zhou Yi's tone was stern, even angry.

Maddow, the entire School of Physics is not considered to be world-class, but it has to be world-class.
Bringing together big names under the Nobel Prize from all walks of life,

In particular, the construction of CEPC absorbed a large number of theoretical physicists and spent a lot of money.

There's no reason this can't be done.

If everything depends on Zhou Yi, then there is no need to make breakthroughs in these technologies.

The professors were a little stunned, they didn't expect Zhou Yi's tone to be so tough today.

Wang Yifang bit the bullet and said:

"Professor Zhou, we want you to help us see if we can optimize the mathematical model or the physical model.

We all refer to the shock absorbers in other places, and make some innovations and improvements.
If it can be improved, it will be better for the follow-up. "

Only then did Zhou Yi loosen his brows and said:
"Okay, send me the paper, and I will reply to you within a week."

After Zhou Yi finished speaking, Wang Yifang and other talents were relieved.

"Okay, Professor Zhou, then we will leave first."

Wang Yifang and others said.

Everyone looked at each other and couldn't help but smiled wryly.

Before he knew it, Zhou Yi had developed an air of superiority.

Whether it is the status of the dean, the Nobel Prize winner, or the favor of the above,

As well as various scientific research achievements, they are all admirable existences.

After they left, Zhou Yi's thinking about CEPC opened up again.

Now the cooperation with Europe is deepening day by day, and technologies such as particle use in medical treatment can also be shared.

Therefore, the only function of CEPC is that it has huge uses in controllable nuclear fusion and the discovery of new particles.

If it is really possible to knock out supersymmetric particles, Edward Witten, Qiu Chengtong and others may be able to directly become gods.

However, in order to prevent Europeans from keeping a hand, their own research and development must continue.

Therefore, CEPC still needs to be repaired halfway through, and it is impossible to give up halfway.

The money was paid by Zhou Yi himself, and the labor cost was also hired by Zhou Yi, so there was no reason not to continue the repair.

Not long after, a huge PDF file was sent to Zhou Yi,
Zhou Yi saw that it was Wang Yifang, so he opened it and took a look.

The shock absorption device is a very important link.

Can't be sloppy.

The energy provided by the waves from one earthquake can run CEPC many times over.

Zhou Yi looked at their abstracts, and started with the generalized mechanical model and fractional mechanical model that have attracted much attention in recent years.

This kind of thinking is indeed quite popular, and it also has a certain degree of practicability.
As for their innovations, Zhou Yi still has to read slowly. If they can't be streamlined, they will follow this idea.

PS: There are pictures of the sixth-generation machine in the book review, and the references of this book will be updated in the book review later.
