Chapter 649: The meter wave radar is getting stronger and stronger
Wasteland Village Base.
"Hey, what's going on today? The J-31A is back again? And it's still black-skinned?" Pilot Zhang Yongchao looked at the plane that appeared in the parking area and asked very curiously.
The first batch of carrier-based aircraft pilots have graduated and have all flown on the 001 aircraft carrier. Zhang Yongchao belongs to the second batch of pilot students. Like the first batch, they are also studying hard and practicing hard to get on warships as soon as possible and become qualified carrier-based aircraft pilots.
.
Their usual training is either a trainer aircraft or a single-seat J-5. Although there was a J-31A stationed here some time ago, after this aircraft completed the takeoff and landing of the aircraft carrier, it left the wasteland village.
Base, there is no need to stay any longer.
Now, unexpectedly, I saw another J-31A, and it had also been coated with stealth coating. What does the sudden appearance of this aircraft mean?
There were some ground crews busy nearby. Zhang Yongchao walked over curiously and asked one of them: "Hey, brother, what are you doing here?"
"Maintaining the aircraft."
"What about after maintenance?"
"Let it fly."
"What happens after the flight?"
"Go on and take care of it."
Zhang Yongchao shook his head helplessly. This is a chicken-and-egg answer, a never-ending cycle.
"Forget it, we have confidentiality rules. If you shouldn't pry, don't pry. Hey, it seems that a Yunba is flying over?"
The Yunba landed on the runway, and the cabin door at the back opened. Then, large boxes were unloaded one after another, and a row of large characters were spray-painted on the outside: Capital University of Aeronautics and Astronautics.
"What is this? A drone developed by a university in the capital?"
"That's right, it's a drone. This is our latest Seagull drone." A person who got off the plane said and began to instruct everyone to unpack. After unpacking, Zhang Yongchao opened his eyes wide and looked at it in disbelief.
The drone inside: "Is this a coaxial inversion structure?"
The Navy has imported Lao Maozi's carrier-based helicopters, which have a coaxial reversing structure, are short and tall, and are in sharp contrast to other helicopters.
The same is true for the aircraft in front of me. It is unmanned, so it does not have a cockpit. The entire aircraft body is like a short and thick airship. There are two rotors on it, and there are only two rudder surfaces at the tail.
Tail rotor, this method makes the rear mechanical structure simple, while the aerodynamic force is symmetrical, the controllability is good, and it is very suitable for unmanned driving.
This is the UAV that Capital University of Aeronautics and Astronautics first flew in 1995. It has been improved and improved in the following years. Now, it has finally been put into use, and ten of them have been brought! The R&D team is very excited.
.
"This is too strange. Is this a big move?" Zhang Yongchao said curiously.
"To test the air defense system of our new warship, our seagulls can fly low against the sea to see if the air defense system of the new warship can detect us," the visitor said.
New warship, air defense system? Zhang Yongchao immediately reacted: "It's our 052c that is about to be tested!"
"Report, the base leader ordered that all pilots go to the conference room to gather for a meeting!" At this moment, an orderly ran over and shouted to Zhang Yongchao.
"Got it, I'll be there right away!"
The base conference room was bustling with excitement. When Zhang Yongchao entered, he heard them all talking in low voices about something like 346 radar, hundreds of targets, etc., which kept reaching Zhang Yongchao's ears.
"Okay, stop talking, let's have a meeting now!" The base leader walked in and looked at the lively pilots below: "We have just received a mission. In order to test the air defense systems of our 052b and 052c destroyers, we need to dispatch ten aircraft
, as high-altitude targets approach the warship, we plan to dispatch five J-15s and five training aircraft, flying at an altitude of 20,000 meters and 15,000 meters respectively."
"Report, is the J-31A also going to be mixed into our formation?" Zhang Yongchao raised his hand.
"It's not your turn to speak yet!" The leader glanced at Zhang Chao with dissatisfaction. No matter which batch he was in, there would be highly skilled pilots. Not only were they highly skilled in flying, but they also had a bad temper, just like this one.
Zhang Chao is a bit undisciplined and actually interrupts when the leader is speaking!
"The J-31A will fly at an altitude of 18,000 meters, sandwiched between our two formations. This arrangement is to better confuse the other side. At the same time, our five fighter jets each carry two
YJ-81 anti-ship missile target."
What?
At this moment, all the pilots couldn't help but cheer.
Missiles are very expensive, so they usually have no chance to shoot missiles. Occasionally, they hang rocket launchers under the wings and practice shooting at ground targets. This thing is dangerous and has no sense of achievement.
Now, they finally have a chance to shoot missiles!
Missiles are big things! Moreover, they are anti-ship missiles!
"Report, I have a problem!" Zhang Yongchao raised his hand again.
"what is the problem?"
"I think the range of the YJ-81 missile is too close. We need to fly fifty kilometers away from the target before launching, and our route is also limited to high altitude. This is very inappropriate. I suggest that we fly in at ultra-low altitude.
Only in this way can we better simulate actual combat!"
"Ultra-low altitude? According to the exercise arrangement, targets at ultra-low altitude and within fifty kilometers belong to the shooting zone. The target warships can launch missile attacks without hesitation! Zhang Yongchao, do you dare to fly over? You are not afraid of being shot down by Red Flag Nine.
?”
"I'm not afraid of reporting, everything should be close to actual combat!"
"You are not afraid of death. I am afraid of the loss of the plane you have." The base leader glanced at him: "Fly according to the original plan, launch anti-ship missiles at an altitude of 20,000 meters and 80 kilometers away from the target.
Target missile, and then return!"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! The Eagle Strike 81 is a solid-engine anti-ship missile with a maximum range of only 40 kilometers. For air-launched anti-ship missiles, the range is related to the launch altitude and speed.
The higher the altitude, the greater the speed, and the farther the range. If it is launched from an altitude of 20,000 meters at high pressure sonic speed, the range will be increased to more than 60 kilometers.
However, now it is required to launch at a distance of 80 kilometers. What does this mean?
This is obviously because they are afraid of damaging the warship. In fact, it is just a target missile and has no warhead at all, so it is also afraid of danger.
Zhang Yongchao stopped talking. He may not care about his own life, but he can't care about his plane. For every pilot, he needs to care for the plane as much as he cares for his own life. Even if he doesn't care for his own life, he still has to. Take good care of the aircraft.
"Now, let's discuss specific tactics." The leader continued to issue orders.
On the majestic sea, warships are breaking through the waves and overcoming obstacles.
The shapes of the two warships are full of modern feeling. Compared with the messy superstructures of the past, they appear very simple.
Starting from the bow of the ship and back, there is a fold line, and the buildings above the fold line begin to shrink back. This simple method can play a very good stealth role.
However, the shape of the extending superstructure is somewhat different. The 052b with four small shields looks taller, while the 052c with four large shields looks thicker.
The two warships sailed in formation as if they were brothers.
"These two warships look good." Wu Shengli stood on the bridge of 052c, looking at the sister ships, and said with emotion.
"Yes, in the past ten years, our domestic shipbuilding technology has developed rapidly. Our two destroyers are enough to make Europeans envious."
Europe has long wanted to build an air defense ship, but after so many years of doing so, it has not been able to do so. Different countries have different needs, and the coordination of weapon systems is not easy. Later, each of them worked separately, and progress was still slow.
Twenty years ago, when the East had just opened its doors, all the Western weapons we saw were advanced. At that time, we even considered introducing Sea Dart missiles from the United Kingdom and equip them on the 051 destroyer, and even gave it a 051 number.
Due to various reasons, the 051 project was ultimately aborted. For a long time, the fleet in the East was running naked. The navy once envied the West, but now it is the West's turn to envy itself!
"Dad, when the warships are put into service in the future, we can go out more and show our advanced Eastern technology in front of Westerners, so as not to keep the West discrediting us." Qin Tao said.
Many Western media have been reporting on the situation in the East with colored glasses. In their mouths, the East is backward. The East cannot even afford electricity and still uses kerosene lamps. The reports are one-sided.
Warships are not only weapons, but also a window to show one's strength to the outside world. Send warships out to the ports of other countries, let the citizens come to visit, and let them see that the warships built by the East are better than their own. Strong, so that the outside world can better understand the East.
At this time, after hearing Qin Tao's words, Wu Shengli smiled: "Taozi, are you thinking of the recent smear rumors on the Internet?"
Of course, Wu Shengli also knew about this matter. Those rumors regarded him as a big backer of the Mingzhou Group, saying that he protected his son-in-law and undertook various naval projects.
He is not afraid of investigations, and his integrity is not afraid of shadows. Over the years, the Navy has relied on the Mingzhou Group to develop and grow. The old leaders are clear about the contribution of the Mingzhou Group to the Navy. This is not about the Mingzhou Group getting involved in the Navy.
The advantage is that the Navy took advantage of the Mingzhou Group!
However, if these rumors spread, they will still have a bad impact on Mingzhou Group and him.
"No, it's just a trivial matter. Since there are ignorant ants blocking the road, just trample them to death." Qin Tao said: "Dad, you should know that I said this so that Mingzhou Group can sell
Let’s send more foreign trade warships.”
Sending out this kind of warship with four shields and letting the world see the second Aegis system in the world will definitely promote the Mingzhou Group. The Mingzhou Group will gain higher prestige, and the sales of warships will also increase.
Can go to the next level.
"But our navy will not allow this kind of warship to be sold."
"This is just a propaganda method. Even if 052c is not sold, 054 can always be sold." Qin Tao said: "What we want to show to the outside world is the confidence of a strong motherland!"
Some people are working hard for the strength of the motherland, while others are sparing no effort to slander the motherland. No matter at any time, there is no shortage of traitors.
In the capital, in an Internet cafe near a university.
The cigarette butt was emitting wisps of green smoke, and a large part of it had been burned, and then it fell to the bottom with the movement of the mouth.
Pan Han, who had a sharp mouth and monkey cheeks, didn't bother to take the cigarette butt out of his mouth. Even though the smoke had made his eyes start to cry, he was still typing on the keyboard with both hands.
He didn't know how long it took, but he suddenly felt as if everything around him had quieted down. When he raised his head, he found a man holding a camera, pointing it at his screen, and filming himself.
"Hey, what are you doing?" Pan Han turned around in surprise.
"Are you Pan Han? Long live the domestic products of the Internet Island." Next to the camera, another man in a suit and leather shoes said.
"Yes, it's me. What's wrong? Does it have anything to do with you?" Pan Han had a cigarette butt in his mouth and his words were unclear.
"I am a lawyer from the legal department of Mingzhou Group. You have made many inappropriate remarks on the Internet, which have seriously damaged the reputation of our Mingzhou Group. Therefore, on behalf of Mingzhou Group, I solemnly tell you that we have submitted a request to the court.
A complaint has been submitted. You need to apologize to us for these inappropriate remarks, and then compensate us one million for reputational damage. It is estimated that the court summons will be sent to you soon, of course, it may be sent to you first.
Your college."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! What?
Pan Han was shocked by these words. He didn't expect that Mingzhou Group would actually come to his door and ask for one million more?
ah!
Pan Han suddenly exclaimed, without holding the cigarette butt in his mouth, it went directly along his collar and into his stomach. He was so burned by the cigarette butt that he grinned and quickly reached out to take it out.
The visitors had already turned around and left. Looking at their leaving figures, Pan Han's heart was beating violently.
Pan Han was born in a special family. His uncle ran to the other side of the country after the civil war. In the past few years, he came home to visit relatives, but he was envious of him. After that, he began to yearn for foreign countries more and more.
After he was admitted to university, he even found ways to get close to the foreign students in the university. Under their influence, he was full of yearning for the Western world. He was already a banana man with yellow skin and white heart.
Pan Han felt his legs tremble a little. One million is a huge sum of money for anyone! What if the money is not paid? Do you want to spend the rest of your life in prison?
There are no old people in this era. If you don't pay back the money you owe, then you go in and squat. He took a few deep breaths, then opened cq and started asking for help in a special group there.
Help, Mingzhou Group wants to sue me and ask me to compensate one million!
What are they afraid of? If they sue, they may not win!
That's right, this time it's time to leave the Internet and show the dominance of the Mingzhou Group in the real media!
Don’t worry, long live the island’s domestic products, we are all supporting you behind the scenes!
Even if you lose the lawsuit in the end, we will find a way for you to collect the money! Besides, this lawsuit cannot be lost!
The support in the chat group finally allowed Pan Han to regain his composure. He picked up half a cigarette, continued to light it, and started smoking.
At sea, Qin Tao didn't take this little ant seriously at all. The strength of the navy was his most important thing.
"Attention, we are about to arrive at the test sea area. The sea area has been cleared. Air Police 2000 is responsible for judgment four hundred kilometers away."
So far, the Navy does not have an early warning aircraft. This major test project can only be to lease the Air Force's Air Police 2000. This early warning aircraft rarely has the opportunity to monitor so many targets. It can just test the performance of the Air Police 2000.
.
"052c has turned on the search radar!"
"052b has turned on the search radar!"
"Open the data link and transmit it to the rear in real time!"
The judgment not only depends on Air Police 2000, but the Navy itself also has a way, that is, its own data link, which sends all the air defense data back through the data link, and then performs synchronized judgment at the rear.
The antenna of the Type 517 meter-wave radar rotated.
This kind of antenna is quite special. It has a crossbar. The top and bottom of the crossbar are each equipped with four 90-degree vertical horizontal poles. This layout earned it the nickname of a clothes drying rack. However, there is also a horizontal pole on this horizontal pole.
A small horizontal bar looks like a fish bone, so it is also called a fish skeleton.
From the outside, this kind of radar seems to be very old, but the only thing that is old is its antenna and its internal circuit, which have been undergoing substantial changes.
Specifically, the 517 type was developed based on the Jing 17 radar. It started in 1976 and was finalized in 1986. After it was finalized, its performance had lagged behind. Therefore, domestic technicians worked non-stop to develop another 517a radar.
, as for what is now stamped on the 052c destroyer, it is the further improved 517b radar. As for the direction of its improvement, of course it is the ability to counter stealth aircraft.
However, until we boarded the ship, we did not have any confrontation with the J-31A that was coated with stealth coating. Therefore, the ability to detect stealth aircraft is still unknown for the time being.
Now, it is a test for this radar.
The atmosphere on the bridge became tense, and Wu Shengli asked curiously: "Aren't you going to turn on the phased array radar?"
"What we are simulating now is a patrol situation. We first use meter-wave radar to detect, and only after the target is detected, the phased array radar will be turned on." Qin Tao introduced: "This also saves some money."
What to save? The first one is to save power. This four-sided phased array radar consumes a lot of power. Even if the warship is matched and the power generation is increased, you can save some if you can, otherwise the warship will continue to operate during the voyage.
If you drive it, you will save yourself thousands of nautical miles.
The second is to save life. The four-sided phased array radar antenna must have a lifespan. It can be used sparingly. There is no need to replace the t/r components when the warship is retired. This is the best.
"Target found, 500 kilometers away!" the radar soldier shouted.
This is the advantage of meter-wave radar! In addition to the benefits of power consumption and lifespan, it also has a huge benefit, which is its long detection range!
The longer the wavelength, the farther the detection distance is at the same power. This is the iron law of radar. Just like in the previous competition in phased array radar technology, 14 chose the band, and the competitors chose the c-band. As a result, the Navy used 14
The reason is that the detection distance of the wave band is longer. The navy must have a long enough detection capability.
Now, the search distance of the meter-wave radar's clothes drying rack is even further! High-altitude targets can be found five hundred kilometers away. Even in the future, after the meter-wave radar also uses the phased array system, it will even be 450 kilometers away.
22 have been found at a distance of kilometers! Some magazines say it, but I don’t know whether it is true or not.
"The main phased array radar is on!"
As the order was issued, Qin Tao seemed to hear the buzzing sound of the generator behind him. He knew that this was his illusion. However, as the four-sided phased array radar was activated, a large amount of electromagnetic radiation was being emitted to the surrounding areas.
Scanning, if you stand in front of the radar antenna at this time, you will probably get static electricity all over your body.
Nearby, on the 052b destroyer, the captain asked anxiously: "What's going on? Our radar hasn't found the target yet?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "There is no report yet. The furthest detection distance of our rotating phased array radar antenna is four hundred kilometers."
As soon as the test started, they were already at a disadvantage, just because they didn't use the ancient meter wave antenna!
Sun Xuewen, who was accompanying the ship, had a confused look on his face. He had already guessed this outcome. After all, they wanted to win based on cost-effectiveness. The performance was not the most advanced, but the cost was low. It was absolutely impossible for them to compete with 052c.
than performance.
Four hundred is four hundred kilometers. Anyway, it's such a long distance. It's just a look, nothing else.
"Four hundred and fifty kilometers!"
"Four hundred and twenty kilometers!"
When the 052c observation target was 420 kilometers away, the rotating phased array radar on the 052b finally made a harvest!
"The target is found! Wait for the next refresh to measure various data and pass it to the air defense missile system!"
Their antenna is rotating, not fixed! Therefore, even if they find the target, it is impossible to obtain all kinds of information immediately. They must wait until the next time the antenna turns over, and then they can determine the target's identity based on the comparison of the two data.
Speed and other information.
Here, the 052c phased array radar has captured the target, and the data processing system moves quickly to classify the t/r components and aim them at a certain target respectively. The data appears on the screen in an instant.
"The first batch to arrive are ten targets, respectively at an altitude of 20,000 meters and 15,000 meters. The targets are very clear and should be fighter planes."
Different targets have different radar echoes and different detection distances. If you want to detect them better, you have to mobilize more t/r components. Now, only a small number of t/r components are used, and it has been completed.
The measurement of the target shows that it is a large target and the radar reflection wave is very strong.
"Meter-wave radar report found that between the two batches of targets, there is an outline of a mold lake. It is not very clear. It may be a stealth aircraft!"
052c warship has discovered the stealth target!
The 052b destroyer here is anxious.
"What's wrong? Haven't we discovered the invisible target yet? If we don't discover it in time during wartime, we will be beaten!"
"Report, it cannot be found for the time being!"
"Damn it, stop the radar and aim all the radar waves in that direction. I don't believe I can't find it!" The captain became anxious.
"No, doing this will cause us to lose the search for other airspace. In this test, there will be a large number of targets flying from different directions!" Sun Xuewen immediately expressed his refusal on behalf of the developer of the warship.
"We also have four small shields, which can detect the target a hundred kilometers away. Anyway, the interception target can only be fired within fifty kilometers. A discovery distance of one hundred kilometers is enough!" The captain couldn't swallow this breath.
