What is the difference between an electromagnetic gun and a railgun?

The general electromagnetic cannon is a coil gun. It is the basic principle of coil winding that generates a magnetic field.

In fact, the power of the coil cannon is already very powerful. Much more powerful than the average artillery. The trajectory is also very straight. The ability to penetrate is particularly strong. There is hardly any armor to block.

The railgun, on the other hand, uses a very long track to accelerate the shell, so that the shell's discharging speed reaches a very terrifying number.

The higher the muzzle velocity of the shell, the stronger the penetration. The more powerful the armor piercing. Or even more than 10 times the speed of sound.

The world's martial arts are invincible, and only fast is not broken.

Not to mention the protective armor of the tank, even the one-meter-thick armor of the battleship could not carry it.

The only flaw is the large size of the railgun.

It requires a long acceleration track.

This track is not easy to arrange.

Armored vehicles on land are certainly not equipped with them.

Only large ships with a displacement of more than 10,000 tons have barely room for equipment. Even a displacement of 10,000 tons is not enough.

Some researchers have found that if you want to equip railguns, the best template is actually a battleship.

Especially the kind of battleships with a large displacement and an oversized width.

After all, the vast majority of railguns need to be deployed horizontally. Vertical deployments are not fully powerful.

However, the battleships had long been eliminated.

Modern air strike forces made the battleship die without a place to bury.

For the time being, no country is ready to re-equip battleships. It's crazy to make a battleship specifically just to equip it with railguns.

No matter how much military spending is, there is no such waste.

As a result, the research on railguns was stopped. Most of the information is shelved.

Now, a certain country has sufficient funds and will definitely move it out. It is not impossible to build a series of battleships specifically for this purpose.

After all, a modern battleship costs billions of dollars. Someone else has money.

Use railguns to fight monsters......

It's amazing......

In addition, laser cannons are also a key research target.

The previous laser cannon has never entered a practical state. Basically, it's a trial and error in the laboratory.

Now, the laser cannon has been pulled out and is ready to be put into real combat.

It's even more powerful than an electromagnetic cannon.

However, both electromagnetic guns and laser cannons require powerful electricity.

How powerful is it?

Preferably more than one million kilowatts.

Obviously, the current earth technology is not up to the level for the time being.

The USS Ford is the most advanced aircraft carrier on Earth. The output power of its nuclear reactor is more than 200,000 kilowatts.

Even if it is all concentrated on the electromagnetic cannon and laser cannon, it will not be enough.

Therefore, there are a variety of techniques that need to be studied.

For example, how to hit electricity in a short period of time, how to strengthen the magnetic field.

In general, the future is bright, and the road is tortuous. If you want to really put into actual combat, it is still relatively difficult in a short period of time.

Does Wang Buan have the corresponding technology?

Yes.

Very much.

Dazzled.

There are too many things for the eye to take in.

In the Transformers' tech tree, there are many electromagnetic cannons or laser cannons.

Until now, laser cannons have been a very important weapon. It's just that the energy it contains is far from what the earth can bear.

Transformers slash down with a sword, and I'm afraid half of the galaxy will have to be reduced to nothing.

That's right, others are just that.

More than 9999 level of technology, is it a joke?

This is an attack of pure energy.

The stronger the energy contained in the laser cannon, the more lethal it is.

Where does the energy come from?

For the time being, only electricity can be converted.

The lighthouse nation's laser weapons are state-of-the-art. They invented the flywheel battery.

Compared with ordinary nickel-based batteries, flywheel batteries have three or four times more power storage. That's a huge leap forward.

However, if you want to really put it into actual combat, the energy of the flywheel battery is not enough.

What to do?

Is hydrogen storage alloy OK?

The answer is no.

That's right. Not even hydrogen storage alloys.

Hydrogen storage alloys cannot provide more than 1 million kilowatts of super power in a short period of time.

So what to do?

Only combustible hydrogen engines.

The rated power of the Panshi 700 is 100,000 kilowatts. It's still some way from 1 million kilowatts.

The next model, the Panshi 800, or the Panshi 900 engine, may be able to provide an output of 1 million kilowatts. Only then will laser weapons be considered truly mature.

The question is......

At present, the Panshi 700 has not yet completed the working condition simulation.

The next Rock 800, wait at least two or three months.

The next [Rock 900, at least two or three months......

Or, just overtake?

Directly on the horse Rock 1000, directly 10 million K?

The answer is no.

Because the grade of raw materials is not enough.

The current high-temperature corrosion-resistant alloy can only withstand a high temperature of 15,000 degrees.

For a 10 million kilowatt engine, the temperature of the combustion chamber will definitely exceed 15,000 degrees. Domino effect. It must be an upgrade of all raw material grades.

It's not enough to simply upgrade the alloy. It is also necessary to upgrade rubber, ceramics, and glass......

None of them will work.

The alloys are divided into hundreds of hard alloys, wear-resistant alloys, copper alloys, etc.

There are hundreds of kinds of ceramics such as barium titanate, silicon carbide, iolite, etc.

There are hundreds of kinds of rubber, such as nitrile rubber, fluorine rubber, butyl rubber, and ethylene propylene rubber.

Glass......

Forget it, I don't want to list it.

In short, it just won't work for the time being. Faith is not enough. Upgrades are not possible.

The faith value needed to upgrade now is simply more ferocious than NetEase's backwater cold, even a big dog like Principal Wang can't bear it......

"Hey, hey!" Pang Xihua found that Wang Bu'an was distracted again.

This guy, sure enough.

Every time he got down to business, he began to wander all over the world.

"Oh, you say. Wang Buan came back to his senses.

"It was hoped that laser weapons could be mounted on top of the Kwafu-class battleships. Pang Xihua said slowly.

"I'm afraid not. Wang Buan shook his head and said, "The power is not enough." ”

"What if it's a small-caliber rapid-fire gun?"

"Air defense?"

"Yes. Air defence. ”

"Oh. ”

Wang Bu'an pondered.

If it's pure air defense, maybe you can give it a try.

After all, the laser power required for anti-aircraft weapons, is not so scary. 100,000 K may be enough.

If one Rock 700 is not enough, install four.

Four engines can provide a total of 400,000 K of electricity. Almost.

However, the ...... of pure air defense

Why did the Kwafu class suddenly emphasize air defense?

"One of our neighbors to the east took the initiative to donate $300 billion to the Lighthouse Nation for research funding. Pang Xihua said slowly, "It is said that there will be more and more to come." ”

"I see. Wang Buan nodded thoughtfully.

I see. Be prepared.

This neighbor to the east is naturally the one who.

If you want to say that the appearance of deep-sea monsters, the biggest impact is actually this island neighbor to the east.

Most of the supplies they need need to be transported from overseas. In particular, bulk cargo must not be separated from sea freight. Especially between island nations and lighthouse nations, sea freight is very busy. Most of the trade between the two countries is by sea. Almost every few minutes, a large ship crosses the central dividing line of the Pacific Ocean.

If the sea is cut off, they themselves will wither and die.

However, it was the appearance of the deep-sea monster that greatly threatened the shipping route between it and the Lighthouse Country.

Now, the sea vessels of both countries are so frightened that they are stagnant.

If you don't destroy the monsters of the deep sea, you won't be able to live a peaceful day.

On the contrary, for the huge Huaxia, the impact may be a little smaller. After all, we have land access.

With enough funding for scientific research, the Lighthouse Nation began to be arrogant again.

They felt that they could destroy the monsters of the deep sea with their military might, and they would ignore other countries.

Now, the J-11 fighter squadron has also been withdrawn.

The military forces of other countries have also withdrawn.

Only a few followers from a major country still gathered in Hawaii to discuss countermeasures.

What about other countries?

Going home, of course.

You stay there, and others not only don't care about the food, but also give you a look, are you embarrassed?

The Germans were the first to walk away.

Lao Maozi also slipped away quickly.

"Look at this. Pang Xihua handed Wang Buan another briefcase.

"What is it?" Wang Buan stretched out his hand to take it.

"Open it for yourself. ”

"Oh. ”

Wang Buan opened the briefcase suspiciously. Inside is a stack of technical information.

Well, that's the real feast.

Satellite shots.

Lenses, to be exact.

The Beidou series of satellites requires a lot of high-definition lenses.

At present, there are only three high-definition cameras in the world: Carl Zeiss, Schneider, and Leica.

Among them, Carl Zeiss and Schneider are both focusing on medical, aviation, aerospace, scientific research, military and other fields. Only Leica is more focused on the consumer camera market.

The world's reconnaissance satellites basically use Carl Zeiss or Schneider lenses. This is also their strong point.

The reconnaissance satellites of the lighthouse country are so powerful, and they also use imported German lenses.

However, this technology is blocked to Huaxia.

We can only buy civilian ones.

You can't buy anything for the military.

It's our Beidou satellite, which needs a military camera.

The technical information in the document bag is the task for Wang Buan: to study a satellite lens with a resolution of 0.01 meters.

"Wow! the accuracy is one centimeter!" Wang Buan pretended to exaggerate.

"It would be nice if we could do it in the micron range. Pang Xihua's face was expressionless.

"Huh. Wang Bu'an laughed dryly.

Micron-class lenses?

Or is it used for satellite shooting?

Do you think I'm a god? Microns are microns?

Is it okay to have a millimeter in the middle of centimeters and microns? 1 meter equals 1000 millimeters?

Now that you haven't even reached the millimeter level, you need microns?

But......

You really don't want to irritate me.

Brother can really do it at the micron level!
