Chapter 180 World-leading design solutions

Jincheng is a pilot city for the Skynet surveillance system. After Xu Yuan adjusted the relevant algorithm parameters and several rounds of actual tests were successfully completed, Li Gaoke immediately convened a press conference in the Public Security Building.

In addition to highly praising the system's related functions, he also announced to the entire city that he would crack down on crime rates.

At the same time, improve the crime detection rate.

Especially after the main functions of the system were demonstrated to reporters, many related reports quickly emerged on the Internet.

In addition, netizens saw that the target person could be accurately found in the city's surveillance footage so quickly, and they all posted comments on the website platform, calling this system amazing.

And it is strongly recommended that it be promoted nationwide immediately.

As for specific project members such as Jiang Jiaming and Guo Zhihang, detailed information has not been announced for various considerations.

Among them was Xu Yuan, who played an important role.

It was only mentioned in news reports that the project team came from Qinghua University.

"This algorithm is amazing. I remember that when the Skynet surveillance system was planned, it covered Jincheng. It can actually quickly find the target's location in the entire city with just one photo."

"I suddenly feel very safe. If someone commits a crime, they will be caught unless they hide their head."

"There's no doubt that once this system comes out, the crime rate will drop sharply."

"Awesome!"

"When will such good things come to our city?"

"Have you noticed that this technology can be used in many fields besides finding people and restoring images?"

"Qinghua's Department of Mathematics has just become famous, but I didn't expect that the School of Computer Science has also started to rise."

"If the hardware performance improves in the future, will it be possible to directly find people across the country?"

……

As the calls for this matter on the Internet grew louder, netizens were curious about who the algorithm developer was from Qinghua, and they also strongly demanded that the Skynet surveillance be promoted in other cities as soon as possible.

The action taken by the higher authorities was very quick, after confirming that Jincheng's crime-solving rate had indeed increased significantly with the help of Skynet.

The new round of promotion cities was immediately announced online, and it was stated that it would be gradually rolled out to the whole country.

When netizens heard the news, they all became excited.

It was at this time that Xu Yuan, who should have been the main subject of discussion, was immersed in deep learning, combining the information to design an active phased array radar for a stealth fighter.

To ensure that the relevant plans can be completed as soon as possible, Xu Yuan basically stays in the office every day.

Even the proof of the Goldbach conjecture was temporarily put on hold.

Fortunately, relying on the efficiency of deep learning and the relevant knowledge in my mind, the active phased array radar solution for fighter jets has gradually taken shape.

The latest generation of domestically produced stealth fighter has an aerodynamic layout and appearance that adopts a canard-style layout of winglets and lifting bodies. The size of the entire fighter is much larger than other overseas fighters.

In particular, the nose area where the radar is placed is very large.

The active phased array radar designed for this purpose is also very powerful, ensuring that the radar can detect at a longer distance.

In addition, there are eight stripes on the nose of the aircraft, which are mainly used to avoid lightning strikes and protect the radar.

After all, the current cost of active phased array mines is relatively expensive.

The entire radar adopts an air-cooled design and has a large off-axis guidance function.

This makes the radar scan angle larger and detect data faster.

The most important point is that Xu Yuan boldly adopted a side array design in the design of the active phased array radar module, which is not available in other advanced overseas fighter jets.

Compared with the traditional radar placed on the nose, radars are also placed on both sides to form a three-sided design.

This can provide fighter jets with a larger detection range.

In addition, corresponding technical optimization has been carried out on the core components of the active phased array radar.

This will increase the yield and reduce costs.

It is no exaggeration to say that if this three-sided active phased array radar is manufactured and applied to stealth fighters, the comprehensive performance that the fighter can exert will definitely rank first in the world.

It has directly leaped from the third-generation aircraft to the world's most advanced fifth-generation aircraft, and is still at the leading level.

That day, Xu Yuan sat alone in the office, continuing to optimize the active phased array radar solution that was almost completed.

Maybe he discovered some other situations, and his brows seemed slightly wrinkled from time to time.

The judge's lips moved as he murmured to himself.

"According to the current design, although the radar's detection distance and scanning range are guaranteed, the radar power has also reached a very high level."

"This will have an impact on the driver's health..."

Compared with the common nose-mounted radar, his design is a three-sided active phased array radar.

The radar power is already much higher than that of a normal fighter jet. Now that the number of radars has increased, the resulting situation can be imagined. Its radiation is bound to have an impact on the pilot's body.

But if you don’t want to give up the long detection distance brought by high power, you can only start from other aspects.

"If we want to protect the driver from radiation, it seems we need to redesign the driver's protective clothing."

As a lot of thoughts emerged in his mind, Xu Yuan quickly made a decision.

That is to redesign the driver's protective clothing.

Because the driving environment of a fighter jet is different from that of an ordinary aircraft, in addition to wearing an oxygen mask, the pilot also needs to wear protective clothing which has various functions.

However, given the particularity of the latest generation of stealth fighters, the anti-electromagnetic radiation performance of the pilot's protective clothing must be improved. The protective clothing of previous fighters cannot be used again.

Fortunately, it is just a design based on the original one, so it doesn’t take too much time and energy.

Time is like a wild donkey, it runs without stopping.

Two months passed in a blink of an eye. With the New Year's Day holiday over, the institute held a work meeting in accordance with tradition in the new year.

Although Xu Yuan was not strictly speaking an internal staff of Jincheng Aircraft Design Institute, he still attended the meeting.

And he is preparing to formally report his design of the active phased array radar solution for fighter jets.

It is worth mentioning that Dai Zhigang and Li Hao will naturally not continue to stay at Jincheng Aircraft Design Institute because the problem of the fly-by-wire flight control system has been properly resolved.

He had already returned to Jinling University.

Even after reporting the relevant design plan, Xu Yuan was ready to return to Qinghua to continue proving the Goldbach conjecture.

When designing active phased array radar, it is also inevitable to use mathematical knowledge.

In this process, a large number of mathematical formulas and theories in the mind will inevitably collide, which can also play a good role in promoting the study of Goldbach's conjecture.

Although the current progress has not been significantly improved, Xu Yuan is full of confidence.

If nothing unexpected happens, it shouldn't take too long for him to get the final proof when he returns to school.

He also had a bold idea in his mind for this paper proving the ultimate problem in the field of number theory.

I even started to look forward to it, wondering how lively the mathematics world would be by then.

……

Monday, June 2008, 1, Jincheng Aircraft Design Institute.

In the spacious and bright conference hall, the main leaders of the institute and researchers and associate researchers all gathered here today with serious expressions.

As for Xu Yuan, he sat together with researchers such as Shen Yamin and Liang Zhanjun.

nine in the morning.

As the meeting officially began, Song Wencong gave a speech first, and then researcher Liang Zhanjun reported on the fighter's flight control system.

During these two months, Liang Zhanjun and his department conducted several comprehensive tests on the fighter aircraft's fly-by-wire flight control system.

This also includes formal flight testing.

As for the results, they naturally did not disappoint, and all performances exceeded expectations.

It can be confirmed that the research and development technology of domestic fly-by-wire flight control systems has reached the world's advanced level.

When Song Wencong heard the news, his face was filled with joy. At this rate of progress, the first flight would be possible soon.

By then, news about the country's latest generation of stealth fighter jets will also begin to be revealed to the outside world.

This is what everyone is most looking forward to.

About half an hour later, Song Wencong finally handed the microphone to Xu Yuan.

Xu Yuan had already prepared for today's meeting.

After getting the right to speak, he had a smile on his face, and as soon as he opened his mouth, he gave everyone present a big surprise.

"After this period of research, I have completed the active phased array radar solution for fighter jets. Now I will introduce it to you in detail."

As Xu Yuan finished speaking, the on-site staff immediately played the presentation on the screen.

At the same time, Xu Yuan handed the detailed plan documents that had been printed in advance to Song Wencong, Shen Yamin, Liang Zhanjun and others.

Because Xu Yuan kept a surprise, he did not tell Song Wencong in advance that the plan had been completed.

So when everyone heard the news, they carefully opened the design plan without any hesitation.

Among them, researcher Shen Yamin was even more stunned. He never expected that Xu Yuan actually completed the plan.

The key point is that he knew very well that Xu Yuan had never asked him for help during this period of time.

He originally thought Xu Yuan had given up, but it turned out that he had a big move.

However, you still need to see it before you can really judge what the plan is like.

Xu Yuan didn't care about other people's reactions and just continued to talk about the contents of the presentation normally.

It lasted about half an hour and was basically finished.

"The three-sided radar design maximizes the radar's detection range and angle, making our fighter aircraft's performance world-leading."

After summarizing again, Xu Yuan sat back in his seat and waited for other people's opinions.

Of course, he himself was very confident, and his description and evaluation of the plan were very realistic.

After all, it is backed by a progress bar panel.

At this moment, Song Wencong and others all focused their attention on Shen Yamin, because he was the only one at the scene who was professionally researching radar.

Shen Yamin looked at Xu Yuan's design plan and some of the new theories and technologies involved in it, and he was so confused that he didn't know how to describe his expression.

In short, he was deeply shocked and finally understood why Xu Yuan was confident in designing an active phased array radar.

Finally, he took a deep breath, slowly raised his eyes to meet everyone's gaze, and gave his comments with great amazement.

"The active phased array radar solution completed by Professor Xu is very advanced. As he just said, it can make our fighter jets reach the world's leading level."
