Chapter 261 The epic enhancement that shocked the entire network [Subscription Request]

As the take-off command was issued, the stealth unmanned bomber was soon seen on the runway. Propelled by the most advanced domestically-made turbo engine, it took off lightly after traveling a short distance.

Like a gliding goshawk, it circled in the air for a few circles and soon disappeared from the naked eye.

Only then did Xu Yuan retract his gaze and turned to look at Jia Yueguang.

"Director."

"Let's go to the drone platform control room, where we can get a better view of the aircraft."

He said this with a calm expression.

Jia Yueguang naturally had no objection to hearing this. He also wanted to see to what extent the aircraft's stealth performance would be improved after using the new generation of stealth coating materials.

So he immediately smiled and nodded and said, "Let's go over and take a look."

The stealth unmanned bomber took off today in addition to cooperating with Zhang Guangyi's team to conduct ground radar tests.

It is also the first verification of stealth performance after replacing the new stealth coating material.

The original stealth unmanned bomber model had a stealth performance comparable to the overseas Ghost stealth strategic bomber, with a radar reflection area of ​​only 0.01 square meters.

Just like a sparrow flying in the air.

If new stealth coating materials are used, the aircraft's stealth performance can be further improved.

This means the stealth performance of the domestically-made stealth unmanned bomber.

It has surpassed the Ghost stealth strategic bomber and become the world's most advanced aircraft in radar stealth technology.

If the problem of signal interception and interference of drones can be solved, it means that the country has its own stealth bomber, and compared with the Ghost stealth strategic bomber, the cost price is very cheap and low, and the relevant shortcomings can be completely made up by quantity.

Just think about it.

What would it look like if a fleet of stealth unmanned bombers went out to carry out a mission?

With its excellent stealth performance, it can penetrate deep into the enemy's rear.

If it is equipped with a quantum communication system, it will inevitably become the enemy's worst nightmare.

When Xu Yuan heard Jia Yueguang's words, he went to the control room where the drone platform system was located without any delay.

Not long after.

As soon as he stepped in, the figures of Zhang Guangyi and Liang Zhanjun appeared in his sight.

Two people were seen standing in front of a system screen, paying close attention to the data index on it, not daring to look away for fear of missing something important. Liang Zhanjun was paying attention to the flight data of the aircraft, while Zhang Guangyi focused all his attention on the radar system.

Through the detection of the ground radar vehicle, it can be clearly seen that the position of the stealth unmanned bomber is firmly locked.

However, this is because the plane has just taken off and is currently relatively close to the ground radar vehicle.

To judge the performance of GaN ground radar, we also need to see how long this detection can last.

After all, as a stealth unmanned bomber flies, it will move far away from the ground radar vehicle every second.

In response, Xu Yuan first came to Zhang Guangyi, and while looking at the radar detection screen, he did not forget to take the initiative to greet Zhang Guangyi.

"What's the situation, Academician Zhang?"

"Come and see, the plane has just taken off and it has been firmly locked by our radar."

"It seems that our ground radar is superior this time." Zhang Guang pointed at the information screen in front of him and showed off to Xu Yuan with a smile on his face.

It was as if he had already seen that he had regained his face this time.

The performance of ground radar exceeds the stealth performance of stealth unmanned bomber.

To be honest, Xu Yuan was not surprised by this statement, and even felt that it was within a reasonable range.

The characteristics of gallium nitride materials themselves can greatly improve the power and performance of radar, so it is normal to detect aircraft movements at a long distance.

His requirements for stealth unmanned bombers are relatively not very strict.

As long as it can surpass the Ghost stealth strategic bombers overseas.

You should know that the Ghost stealth bomber, which is said to be the most advanced, costs more than 2 billion US dollars to build each aircraft.

It is several times more powerful than the domestically-produced stealth unmanned bomber.

If its stealth performance is not as good as that of domestic drones, then the popularity of the Ghost stealth strategic bomber will definitely be greatly reduced in the future.

It is no longer the best in everyone's eyes.

"It is a good thing that we can develop high-performance ground-based radars, which will help ensure the safety of domestic airspace."

"It seems that I should congratulate Academician Zhang in advance."

Xu Yuan's mind was working. When he came to his senses, he smiled and said to Zhang Guangyi that he was happy from the bottom of his heart.

As ground radar becomes advanced and powerful and widely used, no matter what kind of fighter jets the enemy sends, their traces can be detected in advance and corresponding response plans can be formulated in time.

Being able to effectively ensure the safety of the air domain is of extremely high value and importance.

After listening to Xu Yuan's words, Zhang Guangyi felt a little embarrassed.
He did not take the credit for himself.

"The development of domestic radar is possible today, thanks to your solution to the gallium nitride substrate material problem."

"Otherwise, even if you give me another two years, I'm afraid it will be difficult for GaN active phased array radar to come out."

Zhang Guangyi's words were absolutely from the bottom of his heart.

At the same time, I felt very fortunate. If I hadn't asked Xu Yuan for help in optimizing the gallium nitride technology, nothing would have happened today. Not to mention giving him another two years, it might not be possible to develop the gallium nitride active phased array radar even if he was given a few more years.

After all, the prerequisite for GaN radar is to solve the technology related to GaN substrate materials.

It is necessary to be able to produce high-quality gallium nitride films.

Regarding this point, even in the semiconductor field, overseas countries that are at the level of the field are still in the stage of research and breakthrough.

Completely lagging behind the country.

When Xu Yuan heard Zhang Guangyi bring up this matter again, he didn't know what to say.

Just as he was about to respond, he was suddenly interrupted by Liang Zhanjun's voice.

"Academician Zhang."

"I still have confidence in our stealth coating materials. Compared with the last aircraft, its stealth performance is definitely stronger."

"I'm afraid that the stealth unmanned bomber will soon escape radar tracking."

Liang Zhanjun was obviously full of confidence and did not think that Zhang Guangyi had brought out the gallium nitride radar.

It will make its own stealth unmanned bomber nowhere to hide.

After hearing this, Zhang Guangyi smiled faintly and replied indifferently:
"Then I'll wait and see how long it takes for this plane to escape radar tracking."

Xu Yuan saw the bickering between the two, but he just smiled and didn't respond.

After all, we still have to wait for the actual data results to come out to know what the final situation is.

Time passed by minute by minute, until an engineer's shout suddenly rang out, instantly breaking the atmosphere and attracting everyone's attention.

"Zhang Yuan."

"Something's not right."

"The drone's radar signal has disappeared and it has escaped detection by our ground radar vehicle."

"I'm trying to do a rescan."

Zhang Guangyi, who had been confident at first, was suddenly shocked when he heard these words.

The next second he leaned over and put his eyes close to it, carefully checking the various values ​​that appeared on it.

There was a hint of disbelief on his face.

Obviously, Zhang Guangyi did not expect such a thing to happen. He just wanted to confirm whether it was a problem with the radar itself.

However, the final ending is not very satisfactory.

After confirming that the ground radar was operating normally, the stealth unmanned bomber disappeared from detection, indicating that its own stealth performance has reached a very high level.

"The radar signal was actually lost."

"Is this the effect of replacing the new stealth coating material? I guarantee it is better than the Ghost."

Zhang Guangyi had to face the reality. Although he gave a relatively high evaluation of the stealth unmanned bomber, he did not hide the regret in his words at all.

After hearing the engineer's shout, Xu Yuan immediately studied the radar detection data.

It can be seen that compared with the previous test, the gallium nitride radar can lock the stealth unmanned bomber at a farther distance.

And this is the result of using a new generation of stealth coating materials.

If it is replaced with the original version of the drone, I believe that with the performance of the gallium nitride active phased array radar, it can definitely lock the stealth unmanned bomber at a long distance to ensure air safety.

From this perspective, the performance of gallium nitride radar is already very satisfactory.

The thought stayed here, Xu Yuan couldn't help but comfort him:

"Academician Zhang doesn't need to feel any regrets. Judging from the test results, the performance of the GaN radar active phased array no longer needs to be proven."

"I think if it were a Ghost stealth strategic bomber, it would definitely be able to locate it from a long distance."

"This time it's mainly the upgrade of stealth coating materials, which has brought considerable difficulties to ground radar."

Just as he stopped talking here, Zhang Guangyi suddenly raised his hand, with a relieved smile on his face, and said:

"Do not worry."

"I'm not so bad at losing. I'm very happy to see you design such a powerful stealth bomber."

"This shows that our stealth technology is already at the world's leading level."

Xu Yuan listened to everything Zhang Guangyi said and made sure that the other party accepted the result.

Only then did he turn his attention to Liang Zhanjun.

He took the initiative to ask about the stealth performance of the stealth unmanned bomber.

Facing the world's most powerful gallium nitride radar, it can have such outstanding stealth performance. I believe the specific stealth performance must be amazing.

"Professor Liang."

"Has the data on the stealth unmanned bomber come out?"

"Statistics are in progress." Liang Zhanjun did not even bother to look back and quickly generated a test report while speaking.

Soon he handed a document to Xu Yuan.

"The data is out."

Xu Yuan, who had been unable to wait any longer, took the document without any hesitation.

He quickly opened it and looked over, carefully observing the various flight reports during the aircraft testing.

From the above content, we can see that the aircraft's flight speed and altitude have not been significantly improved, and even the maximum range and payload are not much different from the previous first version.

However, these are all very normal things, because the stealth unmanned bomber is perfect. Unless there are new technical upgrades in engine technology and fuselage materials.

Otherwise it will be difficult to achieve significant improvement.

But the stealth performance is completely different. After using the latest generation of stealth absorbing coating materials, the aircraft's radar reflection area is no longer than 0.01 square meters, which is equivalent to being smaller than a sparrow in the air. The stealth performance completely surpasses the Ghost stealth strategic bomber.

It is well-deservedly the most advanced stealth aircraft in the world.

"With such a small radar reflection area, its stealth performance has surpassed that of the Ghost stealth strategic bomber."

As Xu Yuan couldn't help but murmured, Liang Zhanjun next to him also smiled and took over the conversation to agree.

"We were also surprised by this data. We didn't expect the latest generation of stealth coating materials to be so effective."

"Everyone is a little impatient now and wants to see our stealth unmanned bomber make its debut. It will definitely cause a great shock overseas."

"Especially the Northrop Corporation, I'm afraid they can't believe it."

Perhaps because he was too excited at the moment, Liang Zhanjun showed no intention of stopping.

As for the Northrop Corporation he mentioned, it is a military manufacturer from America, ranking fourth in the world and is very large.

It is also the world's largest radar manufacturer and the largest naval vessel manufacturer.

The most famous product among them is definitely the Ghost stealth strategic bomber, which is known as the most expensive.

It is no exaggeration to say that the unit weight price of the Ghost strategic bomber is several times more expensive than the price of gold when it was in service.

This money-eating beast, which cost such a huge amount of money to build, is recognized as the most advanced stealth bomber in the world.

He even said that no force in the world could replicate the Ghost stealth bomber.

But now its stealth performance has been surpassed by the domestically-made stealth unmanned bomber which costs only tens of millions. I believe that if Northrop Corporation learns of this news, it will definitely be devastated.

Xu Yuan certainly understood Liang Zhanjun's thoughts, and he was also looking forward to seeing the reactions overseas.

However, as the top domestic drone currently, and also responsible for strategic bombing missions, it must be kept secret for the time being like a trump card.

It is not yet time for it to officially debut on the world stage.

Perhaps when quantum communication technology makes progress and is combined with drones, the problems of signal interception and interference can be solved.

Then drones will no longer have any shortcomings.

It doesn’t matter whether it is kept secret or not, we can let the whole world know it openly.

The Spirit stealth strategic bomber is not the aircraft with the best stealth performance.

"Stealth performance alone is not enough. The drone's signal may still be intercepted and interfered with, which may lead to loss of control of the drone and an accident."

Xu Yuan looked at Liang Zhanjun and said this, which actually served as a reminder to Liang Zhanjun.

The next second he immediately asked:
"By the way, Dean Xu, is your research on quantum communication going well? I wonder when it can be applied to drones."

"Then we won't have to worry about the enemy intercepting the jamming signal."

In response to Liang Zhanjun's question, Xu Yuan did not keep the question in suspense and gave a general answer.

"To realize quantum communication, we must use quantum satellites to conduct quantum key distribution experiments, which requires a corresponding quantum direct communication system. Currently, this system is still in the coding design stage."

"It is not realistic to realize quantum communication in a short period of time."

When he said this, Xu Yuan seemed to be quite disappointed and regretful.

Although we had the help of the Quantum Innovation Institute, it was only after we actually started the coding design that we deeply understood the complexity and difficulty involved. Even with the assistance of a panel, it would not be possible to complete it in a short time.

What's more, the quantum direct communication system is just the beginning, followed by quantum key distribution and relay stations.

It also requires a lot of time to invest in research.

I really don’t know how long we will have to wait for quantum drones to be put into practical use.

I'm afraid that although our people have successfully landed on the moon, this side is still a work in progress.

But there is no way around it, as research in the quantum field is inherently difficult.

Even if the results are very small, it will cause a huge sensation worldwide, simply because whoever solves the quantum field will usher in a qualitative change in the entire scientific and technological level.

Right now it is just planning for the future.

After hearing what Xu Yuan said, Liang Zhanjun looked a little regretful. It turned out that he had thought too simply.

Xu Yuan just came from Yenching University and proposed the concept of quantum drones. He is very much looking forward to it.

Considering Xu Yuan's ability, the R&D cycle should not be too long.

As long as the research is successful, it will be equivalent to an epic enhancement to the drone.

But now he realized how difficult this project was.

While the two of them were chatting, Zhang Guangyi regained a lot of his confidence in radar.

In particular, it is learned that the stealth performance of the stealth unmanned bomber has completely surpassed the overseas Ghost stealth strategic bomber.

This means that if a ghost stealth strategic bomber from overseas comes over, it will definitely not be able to escape the gallium nitride radar. It is undoubtedly the most advanced radar in the world.

……

Naturally, everyone was busy in the following period of time.

After the test of the stealth unmanned bomber was completed, everyone's attention fell on the red-headed J-20.

We want to conduct a comprehensive test on the new fifth-generation stealth fighter equipped with gallium nitride radar.

More importantly, the red-headed J-20 is planned to debut this time.

After all, since the last time the Wing Loong UAV participated in an air show and achieved perfect performance on overseas battlefields, it has been a long time since a new advanced aircraft was unveiled in China.

Now that the J-20 has undergone certain enhancements, it would be a shame not to show off these two gallium nitride radars.

"This should be the second time the J-20 has been enhanced since it entered service. It's really exciting!"

At this time in the control room, Jia Yueguang was very excited when he saw two red-headed fifth-generation stealth fighters taking off.

As the proudest product of Jincheng Aircraft Design and Institute, the J-20 brings excitement every time it takes off.

The initial version of the domestically produced fifth-generation stealth fighter used engines purchased from overseas and was not 100% domestically produced like the institute's drones.

In recent years, with the continuous improvement of domestic engine technology, various types of engines have reached the international leading level.

The newly produced fifth-generation stealth fighters have basically been replaced with domestically produced engines.

And in terms of speed and control, the performance is better.

If the use of domestically produced engines can be regarded as the first enhancement of the fifth-generation stealth fighter.

So this is the second time.

Upon hearing this, Zhang Guangyi's face was filled with a bright smile, and he was very confident in the red-headed J-20 equipped with gallium nitride radar.

Those who fly fighter jets are all excellent pilots and are very skilled in operating them.

No matter what kind of test instructions can be completed successfully.

At the same time, behind these two fighter planes, there was also a trainer plane. In addition to assisting in the mission, it was also responsible for filming, so that the heroic appearance of the domestically-made fighter planes could be recorded.

The institute specially designed corresponding testing tasks for the gallium nitride radar mounted on the nose of the aircraft.

Maximize the radar's ultimate performance.

Fortunately, we have a clearer understanding of gallium nitride radar.

As time passed, after completing the mission, the two fighter jets and the trainer plane returned safely.

All that remains is to wait for the data to come out.

This time everyone didn't have to wait too long, and Liang Zhanjun soon saw the detailed report.

When his eyes fell on it, his entire face was visibly filled with surprise.

Then he shouted with a trembling voice:
"Compared to the original radar, the detection range of fighter jets has increased by 80 percent after using gallium nitride radar."

"The maximum range is over 500 kilometers, and the situational awareness capability is unprecedentedly amplified."

After he finished speaking, he came to his senses, quickly handed the report to Xu Yuan, and asked Jia Yueguang next to him to check it.

When Xu Yuan saw this accurate data, even though he was prepared, his heart couldn't help but beat faster.

You know, radar is very important for fighter jets.

Fighter jets with powerful radars can gain insight into battlefield situations, predict enemy actions in advance, and maintain advantages in complex environments.

The J-20, currently equipped with a gallium nitride device radar, has a maximum detection range of over kilometers.

You can imagine what this means.

Looking around the world, there is no fighter jet that can compare to it.

It is no exaggeration to say that it is the strongest in the world.

In the following time, when everyone in the institute was celebrating, China News Service officially released a video of several minutes.

Although the video shows two fifth-generation fighter jets that everyone is familiar with, sharp-eyed netizens soon noticed that these two fighter jets were slightly different from those seen before.

The color of the nose is red.

However, just as everyone was sending comments and arguing about what the red nose of the plane meant.

Suddenly, it was discovered that the fighter's radar detection range had become 500 kilometers.

This made netizens unable to hold back and burst into swearing.

It was not until the 14th Institute of the Electronic Technology Group Corporation announced its success in the field of gallium nitride radar through its official account and specifically mentioned that Xu Yuan participated and made significant contributions that everyone finally understood what was going on.

Emotions were completely ignited and people became extremely excited, with related topics quickly topping the hot search lists on major platforms.

The number of comments in the comment section increased like a rocket.

No one expected that such a huge surprise would come suddenly.

"Fuck!"

"We have suddenly conquered GaN radar, and no news of this has leaked out before."

"With a detection range of 500 kilometers, let's ask who else is there."

"So Dean Xu is involved. No wonder the research is progressing so fast."

"Is this an epic upgrade? It's definitely the world's strongest fighter."

“So exciting!”

"It seems that we are the only one that has applied gallium nitride radar to fighter jets. Is this what it means to be a world leader?"

……
