From small town academic to chief scientist

At present, as long as the development of aviation power is discussed, jet engines are still inseparable.

The potential of traditional turbofan engines has been almost exhausted.

It is nothing more than using lightweight materials that are more resistant to high temperatures. Therefore, the adaptive variable cycle engine has high hopes.

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

However, under the same fuel quantity, the adaptive variable cycle engine

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, its maximum range may reach 8,000 kilometers using only the fuel in the aircraft.

The distance of 8000KM can be imagined how far away it is.

Fighter planes can fly back and forth between the southernmost and northernmost areas of Daxia Kingdom.

You can also fly back and forth between the westernmost and easternmost areas of Daxia Kingdom.

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

With the operation of intelligent systems, drones can even fly this far.

This is the sixth-generation fighter jet with artificial intelligence.

If a war breaks out, just let the swarms of sixth-generation fighter jets be unmanned.

Remote voice control, precise command issuance with almost zero delay,

Not only that, but it can also reduce pilot casualties.

When heavy-duty helicopters make a major breakthrough, there will be no unexpected disasters.

Materials can be delivered directly without driving, which is convenient and fast, reducing potential risks to personnel.

The variable cycle aeroengine is a complex multi-variable nonlinear system with up to 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 measured directly with sensors.

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

This is the 6G technology and first-generation artificial intelligence technology that Zhou Yi has spent a huge amount 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, make an augmented model reference adaptive sliding mode control method based on the LQR method.

Next, we augment the model and design a reference model using 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 is used in the research of adaptive sliding mode control methods for variable cycle engine models.

The theory, experiments, and equipment required to develop a super engine are unimaginable.

You can only eat food one bite at a time, and you can't become a big fat man all at once.

Zhou Yi watched Academician Ma stop speaking and said:

"Are you out of ideas for the rest?"

Academician Ma said directly without any hesitation:

"This is indeed the case. We are struggling to use the Lyapunov function or other theoretical methods."

Zhouyi said:

"Actually, this is the right direction, which is to use Lyapunov function."

Zhou Yi said something while writing something on the whiteboard.

"Based on the Lyapunov function based on the state tracking sliding mode control method,

The adaptive law can derive the upper bound estimation of the system perturbation matrix and the upper bound estimation of external disturbance under strict stability conditions.

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

Some words on the whiteboard and Zhou Yi's words suddenly opened their minds.

What was originally an undecided idea has now become a definite idea.

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

As a result, the time cost and financial cost will be unimaginably high.

Now with the help of Zhou Yi, the advantage is that it can save time, cost and money.

To catch up with Chou Country in a short time,

You must know that Chou State has continued to carry out multiple variable-cycle engine research projects on adaptive variable-cycle engines and developed two variable-cycle engines, F120 and F136.

The only disadvantage of doing this is that it cannot train the level of scientific researchers.

I haven't gone through the trials one by one, so the level increase rate is not as fast as expected.

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

They can just do things for Zhou Yi.

Otherwise, I wouldn’t have come here from Shenfei, Shufei, or NPU.

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

After a while, everyone got Zhou Yi's approval and left.

Zhou Yi washed his face in the office, sobered up his head, and then devoted himself to the next work.

The development of sixth-generation aircraft engines is a long-term project with a weak foundation.

Even if we cooperate with Yingfed, Tsarist Russia and other countries,

It cannot be digested in a short time.

This is also the reason why they made up their mind to form an alliance with Daxia.

No country will reject sixth-generation fighter jets.

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

It's self-evident what this means.

What's more, there are also things like Zhou Yi Huabing's space-based weapons and aerospace carrier.

At present, it seems that Zhou Yi has achieved great leadership in some fields.

In fact, the ugly country is unique in the world in the field of fighter jets.

There are two types of variable cycle engines. If Zhou Yi had not led Academician Ma and others to do it,

The country is basically in the exploratory stage.

In the last century, Chou State proposed the theory of variable cycle engines.

From the 1960s to the 1980s, a variety of variable cycle engines were developed.

By the 1980s, variable-cycle engines gradually evolved from being developed by multiple companies to being developed solely by GE.

GE developed the YF120 engine based on DBE-GE21 and DBE-GE23. It is the world's first flight-proven double-external duct variable cycle engine.

However, it did not enter engineering development due to failure in competition with the F119 engine.

Chou Country is a sword, not a dish.

Zhou Yi never looked down upon them.

We all know the gap here, and sometimes we feel desperate when we look directly at it.

But step by step, Daxia Kingdom suddenly changed from despair at the beginning to hope that they can keep pace with each other.

This is the charm of the Daxia nation, this spirit of never giving up, which Zhou Yi is proud of and practices.

As for the xenophiles back then, they now only deeply regret it.

Similar to chatGPT, Chou Country came up with it immediately, and only opened the GPT3 interface to the outside world.

Although it is more open now.

In many areas, there is no doubt about the foundation accumulated by Chou Country.

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

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

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

B and SD are the first letters of the last names of two mathematicians respectively.

The full name is the Birch and Swinnerton-Dyer Conjecture. This conjecture is a famous problem in the field of number theory.

Its essence is to describe the understandable set size of a special indefinite equation (elliptic curve),

The BSD conjecture gives two different indicators - algebraic rank and analytic rank - through two completely different ideas, and guesses that they are equal.

Although the expression of the conjecture is difficult and obscure, it is consistent with some knowledge of number theory that has appeared in textbooks and has been passed down for thousands of years.

It is a further exploration of ancient issues by pursuers of truth since entering modern society.

Regarding the research on this conjecture, the best researchers are the Chinese Academy of Sciences, Daoguo and Yingguo.

The former has emerged suddenly in recent years and has made great efforts.

The latter two are mathematical powers with historical foundations.

Goro Shimura, Davenport, Wiles, and Wiles's teachers all had a deep understanding of this problem.

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

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

There are really very few people who get stronger as they get older.

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

After watching it all afternoon, Zhou Yi looked at several of his disciples who were also dizzy and dark-eyed, and couldn't help but think of something.

After Zhang Jiahui and Jiang Guoyu graduated, couldn't they submit their apprenticeship tasks again?

I was so busy that I forgot about this.

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

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

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

"Submit task three, the task of recruiting disciples."

Two students were sent out, and now Zhou Yi still has two students left to completely complete this task.

Zhouyi actually doesn’t want to end it. If you take a disciple, you can gain mathematical experience.

That was so cool.

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

【Ding. Identifying two student mathematics papers,

good!

Ding, congratulations to the host for gaining 100,000 math experience, 2,000 points, and 6 lottery chances. 】

[Host: Zhouyi.

Mathematics: LV6, 77/100W; (Mathematics level reaches LV6, you are about to reach the highest level of mathematics on the planet)

Points: 16634, .Lottery chance*18. 】

We still need 230,000 math experience to reach level 7.

Thinking of this, Zhou Yi became more energetic in researching the BSD conjecture and NS conjecture.

Mathematics LV7 is definitely among the top mathematicians in the world.

On par with, or even surpassing, Milno, Qiu Chengtong, Deligne and others.

Two millennium problems, plus the previous number theory conjecture,

Enough to become the world's top mathematician.

And he is a mathematician in all fields.

Just when Zhou Yi and Xia Xue were having dinner in the cafeteria,

Wang Yifang came to Zhou Yi with a group of professors from the School of Physics.

Zhou Yi looked at them and said:

"What's the matter?"

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

Huang Shunjian immediately went to pour tea for the professors.

Wang Yifang looked a little solemn and 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 and energy-absorbing device, which is a systematic seismic wave absorption and attenuation modeling method from a mathematical and mechanical perspective.

According to the established attenuation model, an absorption attenuation compensation method based on seismic inversion and imaging is proposed. "

Zhou Yi heard this and said:

"So now do we need to make breakthroughs in mathematical theory, or do we need to do more in terms of physical knowledge?"

Zhou Yi's tone was stern, even angry.

Mu De, the entire School of Physics is not considered to be world-class, but it has to be world-class.

Gathering all the big names with Nobel Prizes,

Especially the construction of CEPC attracted a large number of theoretical physicists and spent a lot of money.

There's no reason why we can't do this.

If everything depends on the Book of Changes, then there is no need for breakthroughs in these technologies.

The professors were a little stunned. They didn't expect Zhou Yi to have such a tough tone today.

Wang Yifang gritted her teeth and said:

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

We all refer to the shock absorbing devices in other places and make slight innovations and improvements.

If it can be improved, it will be better for the future. "

Zhou Yi relaxed his brows and said:

"Okay, send me the paper and I will get back to you within a week."

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

"Okay, Professor Zhou, let's leave first."

Wang Yifang and others said.

Everyone looked at each other and couldn't help but smile bitterly.

Unknowingly, Zhou Yi had developed the aura of a superior person.

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

And various scientific research results are admirable existences.

After they left, Zhou Yi started thinking about CEPC again.

Cooperation with Europe is now deepening, and technologies such as particle use in medicine can also be shared.

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

If supersymmetric particles can really be knocked out, Edward Witten, Qiu Chengtong and others may be able to directly become gods.

But in order to prevent Europeans from holding back, our own research and development must continue.

Therefore, CEPC still needs to be revised after it is halfway through the revision, and it cannot be abandoned halfway.

All the money was paid by Zhou Yi himself, and the labor costs were also paid by Zhou Yi. There was no reason not to continue repairing.

Not long after, a very large PDF file was sent to Zhou Yi.

When Zhou Yi saw it was Wang Yifang, he opened it and took a look.

Shock absorption device is a very important link.

Don't be careless.

The energy provided by the waves of an earthquake can allow CEPC to operate many times.

Zhou Yi looked at their abstract and found that they were based on the generalized mechanical model and fractional-order mechanical model that have attracted much attention in recent years.

This idea is indeed quite popular and has certain implementability.

As for their innovations, Zhouyi has to read it slowly. If it cannot be simplified, it will be done according to this idea.

PS: The book review contains pictures of sixth-generation phones. The references for this book will be updated in the book review later.
