Chapter 415 The Development of Anti-Ship Ballistic Missiles
Qin Tao doesn’t understand aerospace, so he can’t help much. At most, Qin Tao can only provide some financial support and some chip cooperation.
The chips used on satellites are also very difficult. After all, it is very difficult to protect against cosmic rays in outer space. However, the chips used in receiving terminals on the ground are very simple. They rely on advanced chip technology , it is possible to make cheaper and more durable chips.
After visiting the Beidou system, Qin Tao still had a complicated mood.
"Technically speaking, our Beidou-1 is undoubtedly backward. It also requires calculation by the ground receiving station. It takes a long time and the receiver has to transmit signals, which can easily expose the target. However, this is a breakthrough after all. From Starting from nothing, this first step is the most difficult." Mr. Sun's words still echoed in Qin Tao's mind.
Other satellite navigation systems are all global. They achieve global networking by deploying more than twenty satellites in outer space. No matter where they are, more than three satellite signals can always be received overhead. By receiving satellite signals, Able to determine one's own position.
However, Beidou-1 is a dual-star positioning system. There are only two satellites, so the specific position coordinates cannot be determined. It also requires communication between the ground and the satellite, and then calculation. In this way, if the receiving terminal on the ground emits electromagnetic signals, there is a possibility of exposure.
However, after all, this is only the first generation. The problem of availability has been solved first. In the future, the second and third generations will be like the United States and do not need terminals to transmit signals.
“Taozi, a lot of our work in the aerospace field is inseparable from your help.” Wu Shengli said with emotion: “For example, the unit next door is studying the project of anti-ship missiles to attack aircraft carriers.”
Qin Tao's eyes suddenly lit up: "Dad, can we go and have a look?"
“Of course, I want to see it too.”
Qin Tao felt excited in his heart. He had mentioned it many times before, and had even helped get Lao Maozi's sample bombs back. However, he had not yet been exposed to the specific project.
This is the first time.
After entering, the first thing you see in the long workshop is a launch vehicle.
The front of the truck is a HY472 trailer produced by the Hanyang Factory in China, with a 6*6 chassis and all-wheel drive. The front of the truck is a double cab and looks very round, and the thing towed behind it looks like a boiler.
It was a cylinder, about ten meters long and one meter sixty-seven meters in diameter. There were various openings on the side of the cylinder, just like the coal loading port of the boiler.
This thing looks unattractive. Even if it is not covered with camouflage nets, people will think it is towing a boiler when driven out. In fact, this kind of vehicle is currently the most advanced Dongfeng-21 ballistic missile launch vehicle in China! (Many readers complained about the use of party dues before. In fact, it was to avoid taboos. Now I feel that party dues are probably more dangerous, so I might as well use Dongfeng.)
In the past, there were also Dongfeng-3 missiles that could be launched mobilely. However, this missile was liquid and needed to be filled with fuel before launch, which took a long time. But now, it has been replaced by a solid missile that can be set up at any time. beat.
"The huge waves are coming ashore, and the east wind is blowing into the sea." Qin Tao said with emotion as he looked at this big guy.
Wu Shengli was a little curious: "Taozi, what do you mean by this? We can understand the first half of the sentence, but what about the second half? Does our Dongfeng want to board a warship?"
Qin Tao smiled.
There is a theoretical basis for the huge waves to land. After all, the first solid ballistic missile in China is the Julang-1 missile used on the 092 nuclear submarine. After all, it is too complicated to use liquid missiles on nuclear submarines, so we might as well do it in one step. The solid missile came out. After it was built, the superiors were very satisfied. This kind of missile could not only be used at sea, but could also be towed around on land by a trailer.
So, this became a huge wave coming ashore.
However, there is no theoretical basis for Dongfeng to go to sea. From Dongfeng-1 to Dongfeng-5, they are all liquid missiles, which are impossible to install on warships. Only the weird Asan will support them on the helicopter deck of the frigate. Pick up a ballistic missile and launch it.
As for Dongfeng going to sea, we have to wait for a while. After the Dongfeng-31 missile on land comes out, it will be used by the navy and transformed into the Julang-2 missile.
Now, of course it hasn’t started yet.
Faced with Wu Shengli's question, Qin Tao could only smile: "Big waves can go ashore, and east wind can go to sea. Dad, just wait and see."
"Old Wu, why are you here free?" At this time, Mr. Huang came up to greet him. When he saw the people around Wu Shengli clearly, he was surprised again: "Hey, isn't this Mr. Qin?"
(He is not the same as the person who built nuclear submarines before.)
"Mr. Huang, I'm glad to see you. I didn't expect that you are still fighting on the front line at such an old age." Qin Tao stretched out his hand.
The motherland’s national defense undertakings cannot be strong without the silent dedication of a group of scientific research workers.
In the 1940s, Mr. Huang studied in the UK for graduate school and saw the V-2 missile with his own eyes. At that time, he made a wish: he must make his own missile!
After returning to China, Huang Lao invested in the research and development of domestic missiles. In 1960, China's first missile "Dongfeng No. 1" was successfully test-fired, achieving a breakthrough in Chinese missiles from scratch.
In 1964, the "Dongfeng 2" came out, and China made great strides in the missile field. However, these are liquid missiles that seriously lack survivability when faced with a preemptive strike by the enemy and do not have the ability to carry out a second nuclear strike.
So, in 1970, Huang Lao accepted the task and became the chief designer of the first-generation submarine-launched missile "Julang-1". Twelve years later, the "Julang-1" missile was successfully test-launched in the Bohai Sea. China became the fifth country in the world to have underwater-launched nuclear missiles, and also became one of the few countries in the world to have a second nuclear strike capability. .
This is of course just the beginning.
After the success of Julang 1, the country began to carry out the Julang ashore project. After the Julang ashore became Dongfeng 21, it began to develop a more advanced Dongfeng 31.
The old man in front of me deserves a lot of credit.
At this time, Mr. Huang held Qin Tao's hand tightly: "Mr. Qin, I have wanted to meet you for a long time. On behalf of our scientific research team, thank you for your outstanding contribution to us!"
Qin Tao felt a little embarrassed: "The things I made are all easy and don't deserve such praise."
"No, Mr. Qin, besides those missiles, you have something more valuable to us. Have you forgotten that you were assassinated in the capital? After that, you followed the clues and caught the traitor who leaked our latest scientific research secrets! Thinking about this now, we are still sweating. The project we are currently developing has been betrayed by the traitor! Fortunately, we caught it early and our scientific research results have not been released yet, otherwise..."
What Mr. Huang is talking about is, of course, the matter of Guo Qianjun. This man is the deputy chief designer of ballistic missiles and aircraft carriers. It is really infuriating that he will be bribed by the other side. Although this guy has been sentenced to death, it is still not enough to vent his anger. .
“Fortunately, the scientific research results haven’t been released yet?” Qin Tao was a little puzzled.
"Yes, Mr. Qin, this project was promoted by you, so the relevant departments have also passed the decision, and you are the one who has access to the secrets of this project." Mr. Huang said: "Currently, we are studying this project. However, there are too many technical problems, and we estimate that it will take another four to five years to achieve a complete breakthrough."
Four or five years’ time? We didn’t need it in 1996!
Qin Tao frowned.
This kind of technology for ballistic missiles to hit aircraft carriers is of course very complicated. Otherwise, the motherland will not become the only country in the world with this capability. Even if Qin Tao gets back a lot of old Maozi's things, the problem is Lao Maozi was not completely finalized and put into service at that time, and it was still a semi-finished product.
“Let’s go in and talk. Now, I have taken a back seat. Currently, Mr. Zhang is in charge.”
Mr. Huang is over seventy years old. Although he is still energetic, he is older after all. Therefore, the more energetic Zhang Zhongfulai is in charge of the chief designer of anti-ship ballistic missiles.
This weapon system uses the Dongfeng-21, which is just a vehicle. The most important thing is the warhead. If it wants to hit a moving target, the warhead must have the ability to accurately change trajectory and move at any time.
"Last time, Mr. Qin got us Lao Maozi's R-33 warhead. We were deeply inspired. We are currently using a similar biconical structure. However, there are still many problems, such as how to make the warhead accurate. Lock the target." In the laboratory, everyone saw the double-cone warhead and listened to Zhang Gong's introduction.
“As far as I know, our 14th institute has overcome the difficulties of flat-plate aperture radar. Can we use this kind of radar?”
Qin Tao is a layman in this area, and he can only provide some tentative suggestions.
The radars of fighter jets and the radars of ballistic missile warheads are definitely not the same. However, they both observe sea targets, and they are still observing downwards in outer space hundreds of kilometers away. It should be possible for them to be universal.
The diameter of the Julang-1 missile is 1.4 meters. It is said that a radar with a diameter of more than 700 millimeters can also be installed.
"Our missile dives down and sees clutter on the sea. Therefore, the radar needs to be able to eliminate clutter, which requires the pulse Doppler mode." Zhang Gong said: "However, because our missile The diving speed is very fast, and the surface ship moves very slowly, so there is a high possibility that the pulse Doppler radar may filter out the target as clutter."
Qin Tao was startled when he heard this. Is there such a surprise?
In the confrontation between fighter planes, it doesn’t matter if you are discovered by the opponent or even locked. As long as you make a side turn and turn in a direction perpendicular to the enemy, it will be filtered out as clutter, causing it to become unlocked.
The situation we are encountering now is similar to this.
“So, how about using synthetic aperture mode?” Qin Tao asked.
He didn’t know much, but he was familiar with the synthetic aperture mode, which used radar signal scanning to eventually form a pattern, thus turning one-dimensional distance imaging into a two-dimensional plane imaging.
When the missile swoops down, what it sees is not a point, but a picture, and then the target is retrieved from this picture. Isn’t this enough?
"Yes, Mr. Qin, what we currently plan to use is this synthetic aperture mode. However, we are also facing many technical problems. Whether it is the research and development of equipment or the processing of later data, there are a lot of problems. .”
The only mature one in China is the Flying Leopard fighter-bomber. The first synthetic aperture experiment on the radar used was already in the late 1990s, and this technology has not yet been thoroughly studied.
Moreover, for the Flying Leopard fighter-bomber, it only needs to display the image. However, it will not work if it is placed on the current anti-ship ballistic missile, because there are no people in the warhead, and the electronic equipment inside is needed to recognize the graphics and analyze the characteristics of various warships. Simply put, it also requires image recognition and processing. technology!
This is even more difficult. Without advanced processors and advanced algorithms, it is simply impossible to complete this task.
“Lao Maozi is more direct and can solve all problems with nuclear bombs.” Qin Tao couldn’t help but sigh.
Lao Maozi does not have this problem, because Lao Maozi has always been inaccurate and powerful. He can directly use nuclear bombs to destroy the target even if it is a few kilometers away from the target.
But our own side cannot do it. It is very difficult for our own side to ensure accurate hits.
“At present, our Mingzhou Group has invested in Loongson Company, which specializes in developing processors.” Qin Tao said: “Our first product will be a 486-level processor. We hope to help you.”
486 level chip?
Zhang Gong's eyes suddenly lit up: "So, can it be used in a space environment?"
Qin Tao shook his head: "I don't know. However, if we take shielding measures and use it for a short period of time, it should be fine. We can design algorithms based on this chip. When the time comes, our warhead will swoop down and we will be able to see Go to the scene on the sea, and then lock the target. Even oil tankers and aircraft carriers can be distinguished, and there is absolutely no chance of hitting the target wrongly.”
Zhang Gong nodded: "Yes, we are currently studying related algorithms."
When speaking of this, Qin Tao suddenly thought of something: "Now, breakthroughs in these technologies take time, but we also have tricks. For example, would it be easier if we installed an anti-radiation warhead?"
Qin Tao mentioned special anti-radiation missiles when it came to anti-aircraft missiles. Now they can be used on anti-ship ballistic missiles. After all, this thing does not need to filter ground clutter or consider a large number of invalid reflection signals. Just aiming at the electromagnetic emission source is enough.
Zhang Gong nodded: "If it is an anti-radiation seeker, then we can make it. However, what we want to hit is an aircraft carrier. If an anti-radiation seeker is used, it may easily hit the Aegis battleship. "
Although there are various electronic devices on the aircraft carrier, the electromagnetic waves radiated by these electronic devices are not very strong. The strongest one is Aegis. The four-sided phased array radar, in the eyes of the anti-radiation seeker, is The most attractive.
“Since it is easy to make, let’s make this device first.” Qin Tao said.
"Why?"
Even Wu Shengli was curious now.
"If you can't hit the aircraft carrier, you can hit the Aegis. After we make it, let's do a test. At least we can verify that our warhead derailment control is OK." Qin Tao said: "You have to eat in one bite, and you have to live in one bite. Do it bit by bit, so we can get it out within a year, and by 1996, we can test it once."
Wu Shengli frowned. This was not the first time Qin Tao mentioned this time limit. Qin Tao said that the domestically produced advanced anti-ship missiles would be tested in 1995 and equipped on missile boats in 1996. Now, This kind of anti-ship missile is also said to be test-fired. What is the purpose of this?
Thinking about Qin Tao's several times as the prophecy emperor, this statement makes people even more uneasy.
“Taozi, will something big happen in 1996?”
Qin Tao was shocked: "Of course not, this number is very smooth, there is no other meaning. By the way, I have a new idea."
There are some things that cannot be said. As an old father-in-law, won’t you know it when the time comes?
Now, Qin Tao can only cover up the past, and he really has an idea.
“Mr. Qin, please speak.” Mr. Huang said.
Qin Tao is very far-sighted, and Mr. Huang is very curious about what he wants to propose.
“Fly our Qian Xuesen ballistic hypersonic glide vehicle.” Qin Tao said: “In the future, even if the ballistic missile defense system is built on the opposite side, it will never be able to prevent weapons like ours.”
Qian Xuesen’s ballistics!
The ballistics, named after the father of the motherland’s aerospace industry, is certainly quite noble!
As early as World War II, German scientists designed an aircraft called the "Silver Bird" to satisfy Mustache's vision of "bombing the United States across the Atlantic." This kind of aircraft is launched by a rocket. After it rushes out of the atmosphere, it will re-enter the atmosphere at a specific angle, and then glide in the atmosphere. It can even be bounced out of the atmosphere like water floats, and then continue to enter the atmosphere. The purpose of this device The idea is very advanced and can be said to be the prototype of modern hypersonic aircraft.
Qian Lao, who was still in the United States at the time, proposed after studying the technical information seized from Germany that as long as there was sufficiently advanced thermal protection technology, the aircraft could continue to glide at hypersonic speeds at a specific altitude. Based on this theory, Qian Lao designed a hypersonic gliding flight trajectory, also known as the "Qian Xuesen trajectory."
However, this work has always been under theoretical research. After all, the technology is too complex and not yet available.
Balistic missiles still follow ordinary ballistic routes, and the trajectory has been set before taking off.
However, this approach is now starting to fall out of fashion.
Although the Cold War is over, the superpowers on the other side of the ocean have not stopped pursuing absolute security. They have begun to develop ballistic missile defense systems in an attempt to intercept any missiles flying towards their countries. This will disrupt the originally established strategic balance. break in.
If you want to imitate the cat and follow the tiger's example and engage in missile defense together, you will be dragged down. This kind of thing requires huge investment.
So, you can go in the opposite direction and study how to break through defenses. This hypersonic glide vehicle is one of them.
"This kind of warhead can glide hundreds of kilometers in the atmosphere, change its trajectory at any time, and can even maneuver laterally for more than 500 kilometers. In this way, no defensive weapon can intercept it, and it will become our heavenly sword in the future. It can not only attack enemy aircraft carrier formations, but also attack enemy land targets." Qin Tao said: "This kind of aircraft technology is something we must master, so I suggest starting now."
The Dongfeng-17 missile is directly exposed to the outside and looks very spectacular. But what about other missiles? It can be completely covered in the shell. The opponent originally thought it was an ordinary missile, but after flying over, it can glide and fly!
The so-called missile defense is quite difficult. Various ballistics are calculated, and then the encounter in the air is carefully planned. After the interceptor is launched, the target suddenly turns. When the time comes, let's see how they chase it!
“With the current technology, it will be very difficult to use an engine. We can develop a version without an engine. It only needs to glide. In order to glide farther, I suggest using a waverider.”
Now that he talked about it, Qin Tao completely let himself go.
There are two types of this kind of aircraft. The easier one is the biconical hypersonic gliding body. It has a relatively large volume and can easily arrange guidance equipment and warheads. The delivery efficiency is relatively high, and the design is relatively simple, but Its lift-to-drag ratio performance is low and its gliding ability is poor.
The waverider with higher performance than it is the waverider. This kind of shape is more sci-fi and has excellent gliding performance. However, it is a complex multi-curved structure and has extremely high requirements on aerodynamics, fluid mechanics and aircraft thermal management.
Out of excitement, Qin Tao simply drew a sketch on the paper. The warhead of Dongfeng-17 was directly stamped outside and had been inspected many times, so Qin Tao could easily draw it.
When this beautiful appearance was drawn, the people who specialized in missiles were shocked.
“They say Mr. Qin is a genius and can always come up with all kinds of creative ideas. We didn’t believe it at first, but now we are convinced. Mr. Qin, do you, Mingzhou Group, want to set up an aerospace branch?”
This seemed to be a joke at first, but after thinking carefully, Qin Tao really nodded: "Okay, when the country is liberalized in the future and private capital can enter, our Mingzhou Group will also do something Specialized sea launch companies to supplement you.”
“Then we will feel the pressure of competition in the future.”
"I've said it's not competition, it's supplementation. Our directions are different. If we want to develop it, we will develop small rockets that are recyclable and reusable. By the way, Lao Maozi's rocket technology is pretty good. In our aerospace field, have we got it back? Can you use Lao Maozi’s technology? The liquid oxygen kerosene engine is very good!”
