Chapter 319 Radar Stealth Flight Test Verification

Chapter 319 Radar Stealth Flight Test Verification
Xie Kangquan was really shocked!
He knew that Leihuo Technology Company was working on precision-guided bombs, but he didn't expect it to be so advanced, far beyond his imagination.

"Mr. Lin, this precision-guided bomb is too advanced. It can be dropped at an altitude of 10 meters, and the accuracy is within [-] meters!"

Airplanes generally drop bombs at a lower altitude, the better, and even dive down to drop bombs so that the bombs can hit the target accurately, but doing so is also very risky, and it is easy to be hit by ground anti-aircraft fire.

Lin Feng said, "With the development of the times, the history of dropping bombs at low altitudes is over. Our stealth strategic bomber can drop bombs at an altitude of [-] meters and hit the target accurately."

Great!

so amazing!

In addition to being surprised, Xie Kang showed a full look of surprise, "Mr. Lin, I really hope that such a stealth bomber can be manufactured sooner."

"It's coming soon. The overall design will be completed in a few months, and then the production and manufacturing of parts will begin. We will strive to complete the first flight of the first prototype this year."

what!
The first flight of the prototype will be possible this year!
Not only Xie Kangquan, but also the military personnel next to him were inexplicably surprised. This is really exciting news.

"Great, this is the happiest news I've heard." Xie Kangquan said, "I will definitely come and take a look at the first flight."

After staying in Leihuo Technology Industrial Group for a day, visiting the production of Tianlong transport helicopter and Weilong heavy-duty armed helicopter, and watching the final design of this stealth strategic bomber, Xie Kangquan and others accompanied Lin Feng and his party to a certain bomber factory.

"Boss Lin, welcome, welcome!"

"Thank you, Director, we meet again!"

Everyone was warmly received by the factory when they arrived. Zhu Qing, the leader, seemed very enthusiastic and very happy, and shook hands with Lin Feng, Xie Kangquan and others tightly.

Xie Kangquan asked, "Have all the preparations been done?"

Zhu Qing quickly replied, "Everything is ready."

Xie Kangquan waved his hand and said, "Come on, let's take a look at this bomber."

When the group arrived on the tarmac, they saw the bomber from a distance.This bomber is usually painted white, but the color of this one is obviously different. It has a dark gray radar stealth coating on the surface.

As a manufacturer of large bombers, they also have a supporting airport, but the area of ​​the airport is much smaller than that of Leihuo Aircraft Manufacturing Factory. The area of ​​the apron is less than half of that of Leihuo Aircraft Manufacturing Factory, and this airport has only one runway.

"The color of this coating is really beautiful!"

Far away, Xie Kangquan said like this, and other people in the military nodded in agreement. This dark gray has a special aesthetic feeling, which makes people feel very comfortable.

Everyone invisibly quickened their pace and came to the bomber, and then watched it with great interest. Some people couldn't help reaching out and gently touching the stealth coating on the surface of the plane.

Lin Feng also looked at this plane carefully. At the beginning, he felt a little sad. This is our active main bomber. The model is too old. It has been in service since the 70s and [-]s and has been manufactured until now.

Familiar with the history of future development, Lin Feng also knows that if the historical trajectory is followed, even in the 21st century, this bomber will still be the main bomber and will continue to serve.

It is too backward, and compared with Western developed countries, the gap is indeed a little big.

Aside from feeling sad, Lin Feng also secretly rejoiced that he was about to produce a world-leading stealth strategic bomber. It can still support the strength of the military's air strikes.

Everyone looked at the stealth coating on the surface of the plane with great interest. Lin Feng was an expert, and an expert in this field looked more carefully.

The layman looks at the excitement and the insider looks at the doorway.

Lin Feng saw a lot of tricks. The quality of the stealth coating itself is good, but because the aircraft is relatively old, the product of the 70s and [-]s, the radar stealth design was not considered at all when it was designed. Some corners, planes, etc., the reflection of the radar will be very obvious.

After the radar stealth material is sprayed on the surface of the whole machine, the absorption of radar waves will reach a very ideal situation, but these corners and planes still have certain reflections on radar waves.

"Mr. Lin, there is still a big gap between this radar stealth coating and the stealth coating of the B2 stealth strategic bomber."

This is Jiang Ping, the factory's expert in charge of radar technology and a deputy director of the factory's technical department. Not even a semi-finished product.

Lin Feng felt the disdain and unfriendliness of the other party all at once. Sure enough, the rumors were not false at all, and there were quite a few people who were not optimistic about their radar stealth coating at all.

This is open questioning in front of so many people.

Zhu Qing, the leader of the factory, was a little embarrassed, his face turned cold, and he reprimanded, "Minister Jiang, the radar stealth coating of Leihuo Technology Industry Group has reached the world's advanced level, how can you talk like that."

Of course, Jiang Ping was afraid of the authority of the leader, so frightened that he shrank his neck and dared not say a word.

Zhou Limin is different. He is one of the senior managers of the factory and is in charge of the production management of the whole factory. I know, to say that this kind of stealth coating has reached the world's advanced level is just what the people in Leihuo Technology and Industrial Group say."

The meaning is obvious, this is what they boasted, what is the real level, then who knows.

Everyone is not a fool, and they all understood the meaning of Zhou Limin's words. On the surface, he seemed to be talking and laughing, and seemed very friendly, but in fact, he didn't believe in this invisible coating at all. This was in front of everyone. face doubts.

It's really an old coin!
The faces of the people in Leihuo Technology Industry Group all sank, somewhat angry in their hearts.

Lin Feng was calm, and no one expressed any dissatisfaction or anger, but said confidently, "This is indeed the world's leading radar stealth coating, which is one level higher than B2's stealth coating. As for whether it is In this way, whether we are bragging or not, it won't take long for everyone to know."

Zhou Limin, Jiang Ping and others obviously didn't believe it, and the disdain on their faces was obvious.

Lin Feng also didn't go to general knowledge with them, that would only lower his status, how effective this radar stealth coating is, everyone will know in a short time, and it is meaningless to talk about it now.

Zhu Qing was very apologetic, "Boss Lin, don't let your heart down, some of us have never seen the world."

Zhou Limin's face darkened. If it wasn't because Zhu Qing was the top leader, he would have already quarreled face to face.Jiang Ping's position was much lower, at most he was a middle-level employee in the factory, so he didn't dare to show any dissatisfaction with the top leader.

He could only lower his head and think in his heart, could it be that I really haven't seen the world? Impossible, how could the stealth coating of Leihuo Technology Industry Group compare with B2's stealth coating.

Because the atmosphere was rather awkward and subtle, everyone looked around the bomber and then left. It took about ten minutes before and after.

All preparations are in place. Not only has the bomber been thoroughly inspected, but even the fuel has been filled up.

Before takeoff, everyone held a communication meeting.

Not only people from the military, such as Xie Kangquan and others, but also people from the Leihuo Technology Industry Group attended the meeting. Lin Feng personally attended the meeting. In addition, several high-level executives from the bomber factory and Du Hua, a well-known domestic radar expert.

The latest large-scale phased array control radar in China was developed by Du Hua. For this test flight, we only need to check how big the radar signal characteristics of this bomber are when it is flying in the air.

Lin Feng said in front of everyone, "Theoretically, the radar signal signature of the stealth strategic bomber we designed and developed in the air is at most the size of a ping-pong ball."

Before the words were finished, commotion broke out in the meeting room.

This is also the first time that Lin Feng has mentioned the size of the radar signature of this stealth strategic bomber in front of everyone.

This is so surprising!
Everyone knows that this stealth strategic bomber is designed and developed by Leihuo Technology Industrial Group, but they never thought that its stealth performance is so advanced, and its radar signal is less than the size of a ping-pong during flight.

How big is a table tennis ball!

Most of the birds flying in the sky are larger than this, that is to say, the radar signature of this stealth strategic bomber is not as good as that of an ordinary bird.

Jiang Ping was not qualified to attend such a high-level meeting. If he sat here, he would probably think that Lin Feng was bragging. As a senior executive of the bomber factory, Zhou Limin attended the meeting as a nonvoting delegate.

At this moment, disdain was evident on his face.

He thought in his heart, bragging without drafting, the more he said, the more outrageous it really was.

The beautiful country's B2 stealth bomber is so powerful, and its radar signature is bigger than a ping-pong ball when it flies. The radar signature of your bomber is actually smaller than a ping-pong ball.

Zhou Limin openly questioned, "Boss Lin, this is only theoretical. In reality, the radar signal signature should be much larger than a ping-pong ball. The size of one or two square meters is normal."

Lin Feng ignored him. He already knew that this guy questioned him everywhere, and he had no good intentions in his heart. I don't care about you.

Lin Feng continued, "It will take a certain amount of time for our stealth strategic bomber to be produced. First of all, after we verify the radar stealth coating of our active bomber, we have calculated that after spraying the radar stealth coating, the bomber will fly The radar signature should be two or three square meters in size."

Quiet!

The conference room suddenly fell silent!

Is your radar stealth coating really that powerful?

This bomber did not consider radar stealth at all when it was designed, and its own radar reflection area is very large.

Cao Yangdao, the technical deputy director of the bomber factory, "Mr. Lin, the radar signature of our bomber has reached 56.7 square meters. If you spray your company's radar stealth coating, the radar signature can be reduced to 10 square meters." It’s a huge surprise if it falls within 3 square meters, it’s really unbelievable.”

Lin Feng waved his hands confidently, "Whether it will drop to within 3 square meters or not, you will know after a test flight."

"Mr. Du, you are an expert, and I will trouble you with the special radar signal test." Lin Feng said to Du Hua.

As a radar expert, Du Hua certainly knew the great significance of the drop in the radar signal characteristics of this bomber from more than fifty square meters to three square meters. He was slightly excited and agreed immediately.

"Boss Lin, no problem, leave everything to us."

This meeting not only set the standard, such as the radar signal characteristics of the bomber flying within three square meters, but also set the flight route. The plane took off from the supporting airport of the factory, flew a large circle, and then returned to this airport to land.

There will be multiple radar stations for detection along the way, including a large ground phased array control radar, which is also one of the most advanced phased array control radars in China.

The next day, flight verification was ready to begin.

Everyone was in place, the pilot boarded the bomber with radar stealth coating, and the ground crew once again checked the plane before takeoff, everything was fine and it could take off.

Flight command and control room.

The instruments and meters were working, making slight ticking or beeping sounds from time to time. More than a dozen command and control personnel were sitting at their posts, carefully looking at the instruments, meters and various screens in front of them.

The ground radar at the command and control center was also switched on, and the radar signature of the bomber on the tarmac was also displayed on the radar.

Lin Feng, Xie Kangquan and others were all in the command and control room, and through the glass, they could even see the dark gray bomber on the tarmac in the distance.

"You see, the radar signature of this bomber is really different."

"Really, let me take a look."

"Wow, why is the signal signature so weak, this plane is clearly parked on our tarmac!"

"."

Following the astonishment of the radar control technicians, there was a slight commotion in the huge command and control room, and many people became astonished, because the radar signal signature of this aircraft was indeed much weaker.

Du Hua looked at the radar screen in person, then looked at the data on the radar, and waved, "Make a record, and don't miss any data."

Through these data, the radar reflection area of ​​this aircraft can be calculated. Although it has not been calculated yet, Du Hua knows that the radar reflection area of ​​this aircraft is estimated to be only three to five square meters.

Immediately, he felt a little anticipation in his heart, how big would the radar reflection area of ​​this bomber be when it was flying in the air.

Zhu Qing, the leader of the factory, came over, "Boss Lin, Director Xie, everything is ready for takeoff!"

Lin Feng raised his hand to check the time. It was 2 minutes before [-]:[-] am, so he waved his hand and said, "At [-]:[-] am, the aircraft engine starts and the runway is on standby!"

The order came soon.

Not long after, the bomber's engine started, and the roaring sound was transmitted through the glass into the flight command and control room. In everyone's eyes, the plane was heading towards the runway in the distance.

A few minutes later, it was on standby at one end of the runway, ready to take off.

The technicians in the control command room recorded all kinds of data in detail, and paid close attention to the conditions of various instruments and meters, and the conditions were normal.

A moment later, with yet another command, the plane accelerated on the runway and then took off into the blue sky, higher and higher and further away.

After a while, the plane disappeared from everyone's field of vision, completely far away.

At this time, only the radar can keep up with it, and everyone pays close attention to the signals and parameters on the radar.

A large radar station.

They have long received a mission to cooperate with a certain bomber's test flight, mainly to monitor the radar signal characteristics of the aircraft and record detailed data.

The person in charge of this mission raised his hand to look at the time, and made a rough estimate in his mind that the bomber was about to enter the radar range, so he said loudly, "Pay close attention to the radar signal, identify and capture the target."

Several radar soldiers focused on the radar closely.

They already knew the model of the bomber and the flight route of the plane, and they all thought that this was a very easy task and should be within their grasp.

But
As the time passed minute by minute, several signals appeared on the radar, but they obviously did not belong to the bomber.

"Director He, something is wrong!"

The person in charge, He Yun, also found out that the situation was wrong, and couldn't help feeling a little anxious, so he quickly picked up the phone to make contact, and finally confirmed the target's radar signal after some conversations.

This.
Is this the bomber?

If it wasn't for repeated phone calls, and even a radio call with the pilot, He Yun really couldn't believe that this was the radar signal of the bomber, which was completely subverted. Although he knew that the aircraft had a radar stealth coating, the radar signal characteristics would be relatively weak. , but this is too weak.

Fortunately, this is a large-scale ground radar. If it is a general vehicle radar or the like, it may be difficult to find it, at least until the plane is very close.

Ten thousand meters high in the sky.

The dark gray bomber flew a full circle, more than 1000 kilometers, according to the pre-planned route, and then landed at the return airport.

"Mr. Lin, our bomber is about to return."

Hearing the reminder, everyone in the flight command and control room looked outside. After two or three minutes, everyone first heard the roar from the sky, and then saw a black spot approaching the airport in the distance, getting closer and closer. Closer, bigger and clearer.

Our plane is back!

Seeing the plane successfully landed on the runway and taxiing all the way, many people couldn't help cheering. Xie Kang all clenched their fists, and their faces showed a hint of excitement.

After the flight test verification is completed, a verification report will be formed next to take a look at the radar signal characteristics of the aircraft during flight, including the size of its radar reflective surface.
