Chapter 717 You Can’t Click the Electromagnetic Cannon of the Technology Tree Wrongly

Hearing Qin Tao's words, everyone concentrated again: "Anti-missile? Intercept ballistic missile?"

"I remember that this is a technology proposed by President Reagan when he was engaged in Star Wars more than ten years ago, and it has since been proven to be false." Another leader said.

"That's right, the Star Wars plan was fake back then, to bring down the Red Empire, but now, if some people still think that these technologies are fake, then they are deceiving themselves, everyone, 20 years have passed, all kinds of The development of technology is very fast. Didn’t the Americans build a global defense system? Can this thing be fake? Besides, if the Red Empire disintegrated a few years later, laser weapons in space would have been officially deployed. You guys Believe it or not?"

At the beginning, the United States was fooling people, but the old man took it seriously and started to do it. Just before the collapse of the Red Empire, the Polar went to the sky, equipped with a 100 megawatt laser weapon, and used the huge Energy rocket. It's a pity that the rocket didn't make it into orbit.If the Red Empire did not collapse, then the Americans should be dumbfounded. The subsequent improved model is 200 megawatts. After the successful launch, it will be a sharp sword hanging over the heads of the Americans!The old man already has a space-based anti-missile system, but they haven't done anything. In this military competition, they have completely fallen into a disadvantage!

Although it was all a scam at the time, the old man took it seriously, so there is a good saying that Europeans never want to fight the third war, but the old man has always been preparing for the third war. If it really starts, then Lao Maozi's weapons are all adapted to war. The engine will be scrapped within a few hundred hours. Anyway, it can't fly for that long. Most of the electronic systems are electron tubes, which can safely escape the attack of nuclear explosion electromagnetic pulse. If there is a real fight, then the European The weapons at hand will soon be consumed, or even turned into scrap iron, and the whole of Europe will be full of old men.

The red empire collapsed, and the United States was the biggest beneficiary. In order to pursue absolute security, they began to build an anti-missile system, trying to intercept all missiles that might be fired at them, and pursue unilateral security.

How is this different from Star Wars?But it's a scaled down version.

"Calculated based on the [-]-kilometer range of the electromagnetic gun, if we only consider the shooting height, it can properly reach more than [-] kilometers, and the reaction speed is fast, much faster than those rocket-propelled missiles. Our The navy is on the ocean, so it can easily destroy ballistic missiles in the mid-flight and protect the territory of our motherland from ballistic missile attacks.” Qin Tao said: “This is the most important usage of electromagnetic guns. interceptor weapon."

Yankee's fucking, your fucking and other weapons, the interception relies on missiles. When the missile is launched, the acceleration is not high, and it flies slowly, so the interception time will be very long and increase. If the target suddenly changes course at this time, it will be a waste of work.

What about the railgun?As long as the shell leaves the muzzle, it can have a speed of more than Mach 10! (Based on the kinetic energy of 64 megajoules.) The projectile will fly to the target quickly, and it will be difficult for the opponent to dodge!

Of course, when it comes to anti-missile, laser weapons are the fastest. After all, they fly at the speed of light, but lasers also have a big problem: they are severely attenuated in the atmosphere.

Therefore, the Soviets are developing space-based laser weapons, which can be used in outer space without any problem, but on the ground or in the ocean, if they want to penetrate the atmosphere, the laser will wear out a lot.

Electromagnetic guns don't have this problem. The projectile is also subject to air resistance and gravity bending, but as long as it is calculated with a complex algorithm, the influence of these things can be offset. The warhead is equipped with a guidance function to complete the final flight. Goal tasks and everything will be perfect!

If no one studies the anti-missile system, then everyone can guarantee the existing strategic balance, but the Yankees first broke the rules and set up the anti-missile system, then one's own side has to face each other. Anti-missile has become a joke. On the other hand, it is necessary to study the same anti-missile technology.

The navy has a heavy responsibility. After all, many threats come from the sea. If the navy can intercept the opponent's missiles in the middle, it means that the motherland's territory will be safer.

This task belongs to the Aegis battleship, but the Aegis battleship doesn't have that capability yet. It only has the Red Flag IX missile with a range of [-] kilometers. At most, it can only intercept a short-range ballistic missile with a range of hundreds of kilometers like Scud.

In this regard, the domestic technology gap is still quite large.

If you want to achieve this goal, on the one hand, you need to rely on the advancement of Hongqi-[-] missile technology, and on the other hand, you also need to rely on other weapons. If this electromagnetic gun can intercept ballistic missiles, it can get more attention, that is, Get more resources.

From a weapon supported by naval funds to a weapon supported by the state, from an ordinary pre-research project to a national key project!
Ma Ming was very excited. Boss Qin is too powerful. It can be said that his understanding of this weapon is deeper than his own!My vision is only limited to how to use electromagnetic force to shoot projectiles out. If I were the only one to attend the meeting, I would definitely not be able to tell so many ways.

Great, Boss Qin is really great!

Looking at the eyes of the leaders present, Ma Ming knew that everyone was tempted, and he became more confident in this project.

"President Qin, are Americans developing similar weapons?" Someone asked again.

"I don't know about this. I should ask our comrades in the intelligence department." Qin Tao said: "However, no matter whether the Americans develop it or not, they can't stop us from developing it. If we are ahead of the Americans, there is no need for us to follow behind the Americans."

There is no public report now, so Qin Tao can’t talk nonsense. In fact, the Americans are of course also researching. It can even be traced back to 58, when Bostick, an engineer at the Los Alamos National Laboratory, proposed the concept of an electromagnetic railgun. The orbital launch test of the plasma armature was also carried out, but the result of the experiment was that the equipment at that time could not withstand the overload of the electromagnetic gun, and the project was suspended.

Later, in 78, at the peak of the Cold War confrontation, the Americans began to conduct research on electromagnetic guns. At that time, they aimed at electromagnetic railguns. In 85, they also planned to develop electromagnetic guns for anti-armor tanks. , Lawrence Livermore National Laboratory and Los Alamos Laboratory jointly conducted research on electromagnetic rail guns, from theory to practice, and began to manufacture prototypes.

In the 21st century, the Americans continued to develop tirelessly, and even for a period of time, there were rumors that the electromagnetic gun was abandoned, but after a few years, the Americans were still researching, indicating that they were releasing fake news to confuse the public. Competitors, just like them put forward the theory that large aircraft carriers are useless, but the aircraft carriers built by themselves are bigger than one. Although the Americans do not have wars and ignorance, they often fool people, so they should not be fooled by them, and they must think independently just work.

Now, there is no relevant report for the time being, so Qin Tao can't do all kinds of pre-research, but his point of view is also unquestionable: why should we look at other people's, we should go by ourselves!In terms of electromagnetic ejection and interception landing, we are already more advanced than the West! Why does No.1 go to see the actions of No.2 and No.3?

"That's right, Mr. Qin is right!" Wu Shengli said: "Our technology is already the world's number one in terms of electromagnetic ejection and electromagnetic blocking. In terms of electromagnetic guns, we have to make great strides forward. We don't care about others. Let’s make our own! I think this project is worth doing, and it is related to the strategic security of our country, what about you?”

Everyone nodded in agreement.

Qin Tao's mission is complete.

"In terms of technology, electromagnetic guns can be divided into four types, namely coil guns, rail guns, electric heat guns and reconnection guns. The principles of the latter two are relatively new, and there are many congenital technical problems that have not yet been solved. Therefore, we only introduce the first two types." Ma Ming said: "Among them, the principle of the coil gun is very simple, also known as the AC coaxial coil gun."

The principle of this kind of cannon appeared on the projector. In fact, from the appearance, this kind of appearance is very similar to the appearance of ordinary artillery, after all, they are all round tubes.

"The outer one is the accelerating coil, which generates an alternating magnetic field through an alternating current. In this way, the coil in the projectile will generate an induced current and an induced magnetic field. The magnetic fields interact with each other to give the projectile a driving force."

"The electromagnetic railgun is also very simple. It was invented by the Frenchman Villeruber in 1920. There are two straight guide rails on the outside, and a slider in the middle is a projectile. When the guide rail is connected to the current, it can A strong magnetic field is generated between them, and the slider advances under the action of Ampere's force and shoots out of the gun barrel track. In principle, as long as the guide track is long enough, it can eventually reach sublight speed."

These principles are not difficult, even high school students can calculate them, and they often appear in high school electromagnetic field test questions.

However, theory is theory, and practice is practice. It takes a lot of money and energy to transform from theory to practice.

"So, what method should we choose? Or study the two together?" Someone asked.

According to Ma Ming's idea, he intends to study the two together, and finally decide which one is the most suitable, but Qin Tao said from the side: "Analyzing the theory of the two guns, I think the coil gun is better than the rail gun. "

"Why?" Even Ma Ming was surprised: "From the principle point of view, the structure of the rail gun should be simpler."

The coil gun is complicated, the projectile has a coil, and the barrel also has a coil, but what about the rail gun?As long as there are two guide rails, the complexity is not an order of magnitude at all!
But at the same time, he also knew that Qin Tao was very discerning, and there were no problems with the routes Qin Tao chose, so he was very curious about Qin Tao's suggestions, but only curious.

"Of course it's a question of longevity." Qin Tao said: "When the shells of this electromagnetic railgun are fired, the shells must be in contact with the guide rails on both sides, right?"

The projectile is equivalent to the simplified metal rod moving in the magnetic field in the high school physics and electromagnetics problem. This metal rod must be in contact with the guide rail, because the current must pass through it!
The basic formula of Ampere's force: F=B*I*L, B is the magnetic field strength, I is the current, and L is the length of the metal rod. The larger these three quantities, the greater the force, and the magnetic field is also the current To generate, so the current is as strong as possible.

For a strong current to pass through the projectile, both ends of the projectile must be in close contact with the guide rail, which is also the barrel!
After talking for a long time, what's the problem?Of course it was friction!

The advantage of the electromagnetic gun is that it can accelerate the shell to a very high speed. Even if the projectile only obtains 32 megajoules of energy, it means that the speed is as high as Mach 7. At this speed, both ends of the projectile must be close to the bore (rail) Contact, friction can be imagined!

I don't know what the Yankees think, but they have been researching on the electromagnetic railgun all the time. The technology tree is crooked. The longer the time, the more research, the more sideways the road will be!
The rumors that the Yankees gave up the electromagnetic gun started from the life of the electromagnetic gun. The Yankee has been using the electromagnetic railgun, constantly studying, and finally found that there is still no progress: at most ten rounds of shells, the barrel is worn out and cannot be used. up!

Even an ordinary chemical cannon can fire thousands of rounds!The large-caliber artillery used on battleships during World War II can also fire hundreds of shells. This electromagnetic gun is good, but ten rounds are useless. Can it still be used?
In terms of integrated power, the Yankees made a mistake and engaged in medium-voltage AC. In terms of electromagnetic guns, they made a mistake again, developing electromagnetic rail guns, and then said that electromagnetic guns have no future and went the wrong way. Can you blame the way?Weird!
Speaking of this, everyone is an expert: "That's right, if the speed of Mach 10 comes down and you still have to touch it, then the barrel of the gun will definitely wear out early, but won't the coilgun not rub?"

Ordinary chemical guns must be rubbed, because the gas behind must be sealed, and even rotated under the pressure of the rifling, so the bore of the gun wears out quickly. What about the electromagnetic coil gun?It relies on electromagnetic force and does not require airtight gas, but it is not known whether contact is required.

"If the design is ingenious, it can be non-contact." Ma Ming said: "Just like magnetic levitation, the projectiles of the coil gun can levitate and move forward in the barrel, so that there is no friction. Mr. Qin is right, this This kind of gun has more development prospects, but the technical difficulty of this kind of gun will be very difficult, and even in the first five years, we can only conduct theoretical research.”

This is much harder than electromagnetic ejection!But it is the right path. Qin Tao remembers it very clearly. When the Yankees shouted to give up the electromagnetic gun, because there was no future at all, the domestic electromagnetic gun was successfully tested, and there was even news that it would be given to 055 or 076. Assemble, because our side is taking the road of electromagnetic coil guns!They will be scrapped after firing ten rounds, while their own cannons can fire thousands or even tens of thousands of rounds!

Of course, the technology of the electromagnetic coil gun is much more complicated. Its gun barrel looks like an ordinary naval gun. In fact, a large number of coils are arranged in a straight line along the gun barrel. In order to save power, the coils have to be connected in turn To connect the circuit, the shell also needs to have a coil inside, which is very different from the electromagnetic rail gun that can be launched with a simple guide rail.

However, it has more advantages: no contact, no wear, at the same time, high energy utilization rate, and, under the same acceleration, the current requirement is smaller.

Except that the barrel and the projectile are more complicated, the others are common. For example, electromagnetic guns need powerful energy, and an energy storage device that provides sufficient electric energy is required. However, in the research and development of electromagnetic catapults, this energy storage device This has also been resolved.

Therefore, as long as this technical route is identified and the problems of the electromagnetic gun itself are solved, the research and development can be successful!
"It takes five years for theoretical research? Isn't that too long?" A leader couldn't believe it.

"Everyone, this is already very fast." Qin Tao said: "This is a brand-new technological revolution. There is no such easy breakthrough. After theoretical research, it is estimated that the sample gun experiment will take more than five years. We have to do it well. The preparations for more than ten years of research and development work, now that we know the long road ahead, we have to start early, what do you think?"

"Well, it is indeed necessary to start early, and if it is only for theoretical research, it will not consume much, I think it can start." Wu Shengli said.

Everyone nodded.

"How much research and development funding do you expect to need?"

"For theoretical research, about 500 million yuan per year is enough." Ma Ming said, "Of course, if the Navy doesn't support it, then even if we raise funds ourselves, we still have to develop this kind of project."

For the navy, 500 million is indeed not a big number, but after hearing what Ma Ming said, some people were still tempted, but later, Qin Tao said: "If we develop it with self-raised funds, then It means that the whole project is carried out by ourselves, and has nothing to do with the navy. In the future, if the navy wants it, it will charge a high price, and at the same time, it cannot prevent us from selling it to the outside world.”

Ma Ming really planned to raise funds by himself, and he was used to it. Now Golden Sun Motor Company also has money, but when Qin Tao said these words, the navy leaders were not calm.

"This is all for the construction of our navy and for the development of national defense. How can you let you spend your own money?"

"That's right, that is, the funds for this kind of project are of course provided by our navy. Don't worry, it doesn't matter if you spend more than that. The navy will give you an extra 200 million yuan."

A smile appeared on Qin Tao's face. These leaders are all shrewd and know what is the best choice. Electromagnetic guns, such a tall thing, must not be reduced to the outside world casually!

"Okay, since everyone agrees, the electromagnetic gun project will be officially launched, and the funds will be provided by our navy. We will try to wait until the next generation of destroyers is developed, and our electromagnetic guns will be able to be carried!" The tallest person present The leader made a decision.

"The next generation of destroyers?" Qin Tao became curious about this. Does the navy have plans for the next generation of destroyers?
"Yes." Wu Shengli introduced: "When our 002 aircraft carrier comes out and forms a formation, the navy will also need more destroyers and frigates to escort, just as you imagined, we should have [-] tons Destroyers are enough. This is the new generation of destroyers planned by our navy.”

Qin Tao became interested: "When will the bidding be called?"

"Don't worry about this. It will probably take two or three years. After all, we have to wait until all kinds of technologies have made breakthroughs."

"Various technologies? Within ten years, our electromagnetic gun technology will not be mature enough to board the ship. Apart from electromagnetic guns, what new technologies do we have? I, a professional shipbuilder, have never heard of it?"

When Qin Tao said this, he was indeed curious, not knowing what the navy was planning, but after hearing his question, the leader in front smiled: "President Qin, in terms of shipbuilding, If you want to say number two, no one dares to say number one, you plan for us, what kind of technology does our [-]-ton drive have, which is called real progress?"

The [-]-ton large-scale drive is not only an increase in displacement, but also more missiles installed, just like the old Maozi's Kirov-class and Moscow-class, it looks like a modern arsenal ship, but in fact it can't even have an anti-ship missile. Can't stop.

The biggest problem with the Moscow attack was the incompatibility of the fire control system. They only paid attention to the drones in the sky and ignored the sea-skimming anti-ship missiles at sea.

If one's own side builds a [-]-ton large drive, of course it cannot make the same mistake.

"Currently, the relevant personnel of our 14th Institute are developing an improved Sea Star radar, which has changed from air cooling to liquid cooling, and its performance is better. However, only four-sided radar is not enough. If we want to build a [-]-ton large drive, That would require a whole new multi-band radar."

"Multi-band radar?" Everyone became interested.

"That's right, the main force is the four-sided S-band large-scale phased array radar, and a small piece of C-band radar is embedded in this radar array. This is our existing configuration, but in addition to these, we also need to add these On top of the radar front, four X-band phased array radar antennas are equipped."

Multi-band radar is the most important feature of 055. If you use a fashionable name, it is integrated radio frequency technology. Now, since the leader wants to test him, he will of course say it.

"Radars of different bands can be used to deal with different targets. The combination of multi-band radars can have the best detection effect. By the way, if we have meter wave phased array radar, we have to integrate meter wave radar go in."

"With so many radars, how do we solve the problem of electromagnetic interference?" a leader asked.

"These are the problems that electronic experts need to solve, and I am only responsible for providing suggestions." Qin Tao said: "If we want to develop a large-scale drive of [-] tons, we must make breakthroughs in these technologies so that our destroyers have strong detection capabilities. , At the same time, these radars must be able to be integrated, that is, the signals must be processed comprehensively, and they must not fight independently."

The Moskva is fighting on its own, with its head disregarding its back, and its own 055 must not make such mistakes. Anyway, he is only responsible for giving opinions, and how to do it is the business of electronics experts.

The advantages of radars in different bands complement each other, and with coordinated operation, the detection capabilities and information acquisition capabilities of the entire warship can be greatly improved. This is a must-have capability for a [-]-ton large-scale drive!
