Chapter 717: Don’t click on the wrong electromagnetic gun in the technology tree

Chapter 717 Don’t click on the wrong electromagnetic gun in the technology tree

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

“I remember that this was a technology proposed by President Reagan when he was working on Star Wars more than ten years ago, but it has since been proven to be false,” another leader said.

"Yes, the Star Wars plan was fake back then, and it was to bring down the Red Empire. But now, if some people still think that these technologies are fake, they are deceiving themselves. Everyone, twenty years have passed. This kind of technology is developing very fast. Didn’t the Americans still build a global defense system? Can this thing be fake? Besides, if the Red Empire disintegrates a few years later, laser weapons in space will have been officially deployed. Do you believe it?"

The United States was deceiving people at first, but Lao Maozi took it seriously and started to do it for real. Just before the collapse of the Red Empire, the Polar HMS went into space, carrying a 100-megawatt laser weapon and using the huge Energy rocket. It's a pity that the rocket failed to reach orbit due to problems. If the Red Empire had not collapsed, then the Americans would be dumbfounded. The subsequent improved model would be a 200-megawatt model. After the successful launch, it would be a sharp sword hanging over the heads of the Americans! Lao Maozi already has a space-based anti-missile system, but they have done nothing. In this military competition, they are completely at a disadvantage!

Although it was all a scam at the time, Lao Maozi took it seriously, so there is a saying that Europeans never want to fight three wars, but Lao Maozi has really been preparing for three wars. If it really starts, then Lao Maozi's weapons are all suitable for war. The engines will be scrapped after a few hundred hours, and they can't fly for that long anyway. Many of the electronic systems are tubes, which can safely escape the attack of nuclear explosion electromagnetic pulse. If there is a war, then Europe The weapons on hand will soon be used up, or even turned directly into scrap metal, and all of Europe will belong to the old man.

The United States was the biggest beneficiary of the collapse of the Red Empire. 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, pursuing unilateral security.

How is this different from Star Wars? But it’s just a smaller version.

"Based on the electromagnetic gun's range of 400 kilometers, if we only consider the shooting height, it can reach more than 100 kilometers. Moreover, 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 mid-flight and protect the territory of our motherland from ballistic missile attacks." Qin Tao said: "This is the most important use of electromagnetic guns. It is the mainstay of our sea base. interception weapons."

Damn it, you **** weapons, etc., interception relies on missiles. When missiles are launched, their acceleration is not very high and they fly slowly. In this way, the interception time will be very long, which increases If the target suddenly changes course at this time, the work will be completely in vain.

What about the electromagnetic gun? As long as the cannonball leaves the muzzle, it can reach a speed of over Mach 10! (Calculated based on 64 megajoules of kinetic energy.) The projectiles will fly to the target quickly, making it difficult for the opponent to dodge!

Of course, when it comes to anti-missile weapons, 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 are fine for use in outer space. However, on the ground or in the ocean, the laser has to penetrate the atmosphere, and the laser loss is very large.

The electromagnetic gun does not have this problem. The projectile is also subject to air resistance and is bent by the earth's gravity. However, as long as complex algorithms are used to calculate, the effects of these things can be offset, and the warhead is equipped with a guidance function to complete the final flight direction. Target tasks, everything will be perfect!

If no one studies the anti-missile system, then everyone can ensure the current strategic balance. But the Yankees broke the rules first and built the anti-missile system. Then our side will have to fight **** for tat. On the one hand, we must develop penetration technology to let the other side's Anti-missile technology has become a joke. On the other hand, we need 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 missile in the middle of its flight, it means that the territory of the motherland will be safer.

This task belongs to the Aegis battleship, but now the Aegis battleship does not have that capability. It only has the Red Flag-9 missile with a range of 100 kilometers. At most, it can only intercept short-range ballistic missiles such as Scud with a range of several hundred kilometers.

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

If you want to achieve this goal, on the one hand, you must rely on the advancement of Hongqi-9 missile technology, on the other hand, you must also rely on other weapons. If this electromagnetic gun can intercept ballistic missiles, it will receive greater attention, that is, Get more resources.

From a weapon supported by navy funds to a weapon supported by the state, from an ordinary pre-research project to a national key project!

Ma Ming was very excited. Mr. Qin was so powerful. It can be said that his understanding of this weapon is deeper than his own! My vision is limited to how to use electromagnetic force to shoot out projectiles. If I were the only one attending the meeting, I would never know so many tricks.

Awesome, Mr. Qin is so awesome!

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

“Mr. Qin, are the Americans developing similar weapons?” someone else asked.

"I don't know this. You should ask our comrades in the intelligence department." Qin Tao said: "However, no matter whether the Americans develop it or not, it cannot stop our development path. After all, in this field, we have already overtaken others in a corner and have reached the If we are ahead of the Americans, there is no need for us to follow behind them.”

There are no public reports now, so Qin Tao can't talk nonsense. In fact, of course Americans are also studying it. The earliest can even be traced back to 1958, when Bostick, an engineer at Los Alamos National Laboratory, proposed the concept of electromagnetic railgun. An orbital launch test of the plasma armature was also conducted, 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 1978, at the peak of the Cold War confrontation, the Americans began to conduct research on electromagnetic guns again. At that time, the direction they aimed at was electromagnetic rail guns. By 1985, they also planned to develop electromagnetic guns specifically for anti-armor tanks. , Lawrence Livermore National Laboratory and Los Alamos Laboratory jointly conducted research on electromagnetic rail guns, turning theory into practice, and began to build prototypes.

Entering the 21st century, the Americans continued to work tirelessly on the development of electromagnetic guns. For a period of time, there were even rumors that they had given up on the electromagnetic gun. However, a few years later, the Americans were still researching, indicating that they were spreading false news to the outside world. To confuse competitors, it is the same as saying that large aircraft carriers are useless, but each of the aircraft carriers they build is bigger than the other. Although the Americans do not have a war to deceive others, they often deceive others, so they cannot be deceived by them. Just think independently.

At the moment, there are no relevant reports, so Qin Tao cannot do various preliminary research. However, his point of view is also unquestionable: Why should we look at others, we should go our own way! In terms of electromagnetic ejection and arrested landing, we are already more advanced than the West! Why does the first place player watch the actions of the second and third place players?

"Yes, Mr. Qin is right!" Wu Shengli said: "In terms of electromagnetic ejection and electromagnetic interception, our technology is already the best in the world. In terms of electromagnetic guns, we must also make great strides forward. We don't care about others. Let’s do our own thing! I think this project is worth pursuing because it is related to our country’s strategic security. What about you?”

Everyone nodded in agreement.

Qin Tao’s mission is completed.

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

The principle of this kind of gun appeared on the projector. In fact, if you look at it from the appearance, it looks very much like an ordinary artillery gun. After all, they are all round tubes.

“The outside is an accelerating coil, which generates an alternating magnetic field through alternating current. In this way, the coil in the projectile will generate an induced current and an induced magnetic field. The interaction of the magnetic fields between each other can give the projectile a driving force."

"The electromagnetic railgun is also very simple. It was invented by the Frenchman Villeroube in 1920. There are two straight guide rails on the outside, and a slider in the middle is the projectile. When the guide rails are connected to the current, they can move on a flat surface. A strong magnetic field is generated, and the slider moves forward 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 sub-light 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. Changing from theory to practice requires a lot of money and energy.

“So, which method should we choose? Or study both together?” someone asked.

According to Ma Ming's idea, he planned to study both types together and finally determine which one is most suitable. However, Qin Tao said from the side: "Based on the theoretical analysis of the two types of guns, I think the coil gun is better than the rail gun. "

"Why?" Even Ma Ming was surprised: "From a principle perspective, the rail gun should have a simpler structure."

Coil guns are complicated. The projectile has a coil and the barrel also has a coil. But what about the rail gun? Just two guide rails are enough. The complexity is not an order of magnitude at all!

But at the same time, he also knew that Qin Tao was very discerning. There were no problems with the routes chosen by Qin Tao. Therefore, he was very curious about Qin Tao's suggestions, but he was just curious.

"Of course it's a matter of lifespan." Qin Tao said: "When the projectile of this electromagnetic railgun is fired, the projectile 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 high school physics and electromagnetic problems. This metal rod must be in contact with the guide rail because current must pass through it!

For a strong current to pass through this projectile, both ends of the projectile must be in close contact with the guide rail. This guide rail is also the barrel!

Have been talking for a long time, what’s the problem? Of course it’s friction!

The advantage of the electromagnetic gun is that it can accelerate the projectile 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 gun bore (rail). Contact and friction can be imagined!

I don’t know what the Yankees think, but they have been researching electromagnetic railguns all the time. The technology tree is wrong. The longer time goes by and the more research is done, the more deviated the road will be!

The rumor that the Yankees gave up the electromagnetic gun started with the lifespan of the electromagnetic gun. The Americans have been working on the electromagnetic rail gun and kept studying it. In the end, they found that there was still no progress: at most ten rounds were fired, and the barrel was worn out. Got it!

Even an ordinary chemical cannon can fire thousands of rounds! The large-caliber artillery used on battleships during World War II could fire hundreds of rounds. This electromagnetic gun is great, but it is useless after ten rounds. Can it still be used?

In terms of comprehensive power, the Americans made a mistake, developing medium-voltage AC. Regarding electromagnetic guns, they made a mistake again, developing electromagnetic rail guns, and then said that electromagnetic guns have no future. They took the wrong path. Can they blame the path? What a weirdo!

When it comes to this, everyone is an expert: "Yes, if the speed of Mach 10 is reduced and there is still contact, the gun barrel will definitely wear out early, but won't the coil gun have friction?"

Ordinary chemical cannons must be subject to friction, because the gas behind them must be sealed, and they even have to rotate under the squeeze of the rifling, so the bore of the cannon wears out quickly. What about the electromagnetic coil gun? It relies on electromagnetic force and does not require a sealed gas, but I don't know if it requires contact.

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

This is much more difficult than electromagnetic ejection! But it is the right path. Qin Tao remembers clearly that when the Americans were shouting 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 sent to 055 or 076. Assembly, because we are taking the path of the electromagnetic coil gun! They are useless after just ten rounds, but our own artillery can fire thousands or even tens of thousands of rounds!

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

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

Except that the barrel and projectile are more complex, everything else is the same. For example, electromagnetic guns require powerful energy and an energy storage device that provides sufficient electrical energy. However, in the development of electromagnetic catapults, this energy storage device It has also been resolved.

So, 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!

“Theoretical research only takes five years? Isn’t that too long?” A leader was a bit unbelievable.

"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 prototype cannon experiment will take more than five years. We must do a good job We have been preparing for more than ten years of research and development work. Now that we know how long this road is, it is even more important to start it as soon as possible. What do you think?"

“Well, we really need to start as early as possible, and if we only conduct theoretical research, it won’t cost much. I think we can start.” Wu Shengli said.

Everyone nodded.

“How much R&D funding do you expect to need?”

“In theoretical research, about five million dollars per year is enough.” Ma Ming said: “Of course, if the Navy does not support it, then we will develop this kind of project even if we raise funds ourselves.”

For the Navy, five million is indeed not a big number. However, some people were tempted when they heard what Ma Ming said. But later, Qin Tao spoke: "If we raise funds to develop it ourselves, That means that the entire project is our own and has nothing to do with the Navy. In the future, if the Navy wants it, it will pay a high price, and it will not prevent us from selling it to others."

Ma Ming indeed planned to raise funds by himself, and he was used to it. Now Golden Sun Motor Company also had money. However, when Qin Tao spoke these words, the navy leaders became uneasy.

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

"That's right, that's right. Of course, our navy will provide the funds for this kind of project. Don't worry, it doesn't matter even if the cost exceeds. The navy will give you an extra two million yuan."

A smile appeared on Qin Tao's face. These leaders are all smart and know what is the best choice. Electromagnetic gun, such a high-end thing must not be left to the outside world casually!

"Okay, since everyone agrees, then this electromagnetic gun project will be officially launched. The funds will be provided by our navy. We will try to wait until the next generation destroyer is developed and be able to carry our electromagnetic gun!" The highest person present The leader made the decision.

“The next generation of destroyers?” Qin Tao became curious about this. Does the Navy have any 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 10,000 tons of aircraft carriers. The destroyer is enough. This is the new generation destroyer planned by our navy."

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

“There is no rush for this, it will probably take another two or three years. After all, we have to wait until all kinds of technologies have achieved breakthroughs.”

“Various technologies? Our electromagnetic gun technology will not be mature enough to be put on ships within ten years. In addition to electromagnetic guns, what other 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. However, after hearing his question, the leader in front smiled: "Mr. Qin, in terms of shipbuilding, You want to say second, no one dares to say first, you give us a plan, what technology does our 10,000-ton large propeller have to have, which can be called real progress?"

The 10,000-ton cruise ship not only enlarges the displacement, but also installs more missiles, just like Lao Maozi's Kirov-class and Moskva-class ships. They look like modern arsenal ships, but in fact they don't even have one anti-ship missile. Unstoppable.

The biggest problem with the Moskva attack was that the fire control system was incompatible. It only paid attention to the drones in the sky and ignored the sea-skimming anti-ship missiles at sea.

If our side builds a 10,000-ton large-scale propeller, of course we cannot make the same mistake.

"Currently, relevant personnel from our 14th institute are developing an improved Sea Star radar, which has changed from air cooling to liquid cooling, with better performance. However, only a four-sided radar is not enough. If we want to build a 10,000-ton large-scale drive, That would require a completely new multi-band radar.”

“Multi-band radar?” Everyone became interested.

"Yes, the main force is still the large phased array radar with four S-bands. Small C-band radars are embedded in this radar array. This is our current configuration, but in addition to these, we also need to Above the radar array, four X-band phased array radar antennas are equipped.”

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

"Radars in different bands can be used to deal with different targets. When multi-band radars are combined, they can have the best detection effect. By the way, if we have meter-wave phased array radar, we have to integrate meter-wave radar Get in."

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

"These are problems that electronic experts have to solve. I am only responsible for providing suggestions." Qin Tao said: "If we want to build a 10,000-ton destroyer, we must make breakthroughs in these technologies so that our destroyers have powerful detection capabilities. , at the same time, these radars must be able to be integrated, that is, the signals must be comprehensively processed, and they must not work independently."

The Moskva is fighting on its own, focusing on its head rather than its bottom. Our own 055 must not make such a mistake. Anyway, he is only responsible for giving opinions. How to do it is a matter for electronic experts.

  With the complementary advantages of radars in different bands and coordinated operation, the detection capability and information acquisition capabilities of the entire warship can be greatly improved. This is a capability that a 10,000-ton cruise ship must have!
