Everyone understands the principle that the same xing repels each other and attracts the different xing.

This is the most basic performance feature of the magnetic dot force field, and it is also used more and more in our daily life.

The new concept weapon, the electromagnetic gun, takes advantage of this feature.

Simply to describe an electromagnetic gun.

Charging the turret turns it into a magnetic field.

Then charge the shell and turn it into a copolar magnetic field.

Like-sex repulsion, and the cannonball is pushed out of the barrel by the force of the magnetic field.

Excluding other unclear scientific truths and the acceleration of the shell in several stages during the barrel stage, the electromagnetic cannon is actually not fundamentally different from us playing with two magnets.

The same electromagnetic concept can be used in floating trains as well as in military artillery.

It can also be used in the power take-off ranks!

The barrel is a tube.

In the same way, we make a tube.

Put this tube in the water, charge it, give it a magnetic field.

The tube itself has a magnetic field, and then conducts electricity to the water in the tube to create a magnetic field.

And then......

Or the principle of magnetic fields.

The water in the pipe will be squeezed out.

Keeping it in this state will allow the tube to spray water outwards all the time.

Of course, you can imagine how difficult it is to do this kind of experiment.

How do you ensure that the magnetic field of the tube itself does not leak, and how do you ensure that the water in the tube can be magnetized and repulsed by the pipe wall in time.

The detailed truth in it is naturally explored by professional research scientists.

We just need to know a little bit.

The action of force is reciprocal.

The tube is sprayed with water.

The ejected water gives the tube a backward reaction force.

Applying this theory to the propulsion of ships can form a completely new concept of propulsion.

The original boat power was the propeller, which rotated to push the seawater to create a reaction force to propel the hull of the ship.

Superconducting magnetofluid propulsion also uses the reaction force of water flow.

(The advantages and disadvantages of conventional mechanical rotation power and ferrofluid propulsion depend on the study of the party or Du Niang to give you popular science, anyway, everyone knows that this thing is a good thing.) ）

Theoretically, the ultimate speed of superconducting magnetic fluid propulsion can reach ......

150 knots!

Of course, it is impossible to achieve this kind of theoretical data in the real world.

It's like no matter how much you improve a mechanical propeller, you can't push the limits of physics.

Even if you build a propeller that is theoretically perfect.

No matter how much speed you give it to turn.

It has a limit!

Either you spin too fast and can only stir in place.

Either you push the boat too fast and you can't stir the sea, you can't borrow the reaction force.

It's just like you, no matter how fast you run, you still need to step on the ground to generate friction, and it is a truth that you can't really run and fly.

In fact, the superconducting magnetofluid thruster has been equipped and used by Aili as early as two years ago.

Koji had an early idea about the traditional mechanical kinetic energy used by the ship's wives.

It's not all because traditional mechanical power can't run fast.

It's about security.

Conventional mechanical power has a large number of unavoidable drawbacks, such as the complexity of its construction.

A power propulsion system, from the propeller to the shaft pump and gear components, also requires a bulky internal combustion engine to be placed nearby, and the whole system takes up a huge space in the hull power section.

Even if the battleship of the Azure Star is transformed into a ship, the functional parts of the hull are modeled by the core, and this problem still exists.

It's just that it has gone from being a huge machine to a huge mental module.

Superconducting ferrofluids are too much free.

I was able to put the inlet at the bow and the outlet at the stern for pushing.

I was also able to put the electromagnetic work on the bottom of the hull, but the power furnace that powered it was carefully protected on the upper deck.

Follow one's heart.

Theoretically, you can place it however you want.

As a result, not only the anti-vandalism ability is greatly improved, but also better repair, protection and damage management.

……

"Ah~ Don't lock the thrusters of Marina......"

The whole person was hung on the Admiral's tui, and was dragged all the way like a koala.

There is such a young lady hanging on the tui, and Koji has to walk with a limp.,Limp and hard hearted, when I didn't see the truth of the tearful rain pear flower.。

Why do you say that the capital ship in the navy?

Because of the large tonnage of the capital ship.

But why is the tonnage of the capital ship so large.

Because the greater the displacement tonnage, the more space there is on the ship.

The more space you have, the more options you have, and more equipment that may or may not be useful.

Like Ellie, Marina now ranks among the large capital ships with a displacement of nearly 50,000 tons, and the sisters have enough room for the Admiral to toss some of his brains.

At the same time, the ship's mother controls the hull through mental calculations.

Computing power is described as a software driver on a computer system.

Unfortunately, their ability to control their brother is to control all virtual data networks that exist and don't exist.

Lord Admiral can block out a certain function of his ship mother as long as he uses his brain.

Marina hasn't been addicted to superconducting magnetofluid propulsion.

As soon as Hao Er's thought moved, the little ship girl completely lost control of it, so that she could only hold the Admiral Datui and cry so much.

"This is just a trial experiment, didn't you see how much fuel you consumed after running two laps, good ...... When the Admiral thinks of a way, he will definitely let you use this propulsion system in the future. ”

"When is that?" The little ship lady asked.

"......" Hao was speechless.

He couldn't be sure of that.

A single cannon can drain a small city's power.

Superconducting ferrofluids, which are also electromagnetic concepts, also require a lot of energy to operate.

In the original world, they used electricity, but in Avalon it consumed nanocrystalline elements converted from fuel resources by the shipwives.

As soon as the superconducting magnetic fluid propulsion was opened, the consumption brush of the truth went up...... I can't afford to burn it.

It's not that Avalon can't afford that bit of fuel.

It's that the truth can't hold on.

The young lady of the ship raised her head cutely: "The truth is very edible, you can eat a little more and you can run a little longer." ”

The word "swastika" on the Admiral's face is about to burst out.

People say that charging for five minutes and beeping for two hours.

Truth Nai, are you going to do it the other way around?

"No, no, no, the truth is going to be superconducting magnetic fluid, and Brother Admiral will unlock it for others."

"Mm-hmm, I'll talk about it later."

"Solution, solution~"

"Uh-huh, uh-huh."

"Ahhh

Shouting all the way, limping and dragging little Lori all the way.

This scene between the Admiral and the ship's mother frightened many girls and children in Avalon.

Koji finally dragged the truth back to the town guard mansion, and he was so tired that he was sweating profusely and panting.

"What's wrong?"

The wife, who was hiding under a tree and chatting with Veneto, looked at the funny Admiral in amazement.

found the backbone of the main heart, Zhennai immediately let go of the Admiral, ran over and cried: "Woo~ VV big sister, the Admiral...... Admiral: He bullied Truth Nai. ”

Koji: ......

Veneto: ......

Lexington:......

Truth Nai, this cute thing is simply hopeless.

She shouted Veneto, but she was holding Lexington!

Of course, Truth Nai soon found out that she was holding the wrong person, secretly sticking out her little tongue and mistaking the mistake for not finding out.

Truth Na's crying is very effective.

"Smack!"

A certain meter three began to slap the table.

Did Veneto know that she would be particularly cute when she did it?

"The Admiral really thinks that there is no one in the Silent Department, isn't it, why do so many ship girls in the Town Guard Mansion keep bullying my people, ah?"

Yes?

Huh?

Give me an explanation.

Lori stared at her big eyes like a tigress.

People say that slapping the table in anger is ruckering, and Veneto is ...... The whole small body is shaking.

You're too short to shoot the table, and you're going to have a big sister's head, I'm really sorry for you jumping up.

"It's just, when we don't care about the nobody, right?"

Truth Nai is also arrogant.

The two stupid and cute ships glared at the Admiral together.

Koji pursed his lips, this little field couldn't scare him:

"Eldest sister, which eye did you see that I was bullying the truth."

Obviously, it was the Admiral who dragged her back all the way, and I was the one who was so tired that she was sweating.

"Also...... Don't you need to see, the truth Naidu said that you bullied her. ”

"That's it, right?"

"No...... Not so. ”

"Short Protection~"

"Hmph, I'm ...... How about I just take care of it? ”

Facing the Admiral's flat and traceless eyes, Sister Lori's head became more and more empty.

The more familiar you are with this Lori sister, the more Koji discovers that Veneto's strong disguise is soft and cute.

"Brother Admiral locked the superconducting magnetic fluid of Truth Nai, how can Brother Truth cry Brother Admiral doesn't unlock the restrictions for others, good and bad ......" Truth Nai waved her little fist and felt bitter and hateful.

Veneto blinked wide-eyed.

Superconducting ferrofluids...... What is it?

"Poof, don't make a fuss about the truth, Darling must have a reason to do this."

"Ah, but...... However, it was obviously the Admiral's brother who equipped the truth Nai, and the truth Nai only used it very few times, and the admiral's brother only ran for a while at a time and didn't let the truth use it, so angry. ”

Burst.

You're so angry.

Obviously, every time I get angry, it's the Admiral who is the Admiral.

"Nonsense, Admiral, that's for the sake of Truth Na, how much fuel do you say you replenish after every run?" Koji laughed angrily.

"It's not much, and I have to drink a lot every time I come back from a voyage." The football king sister is righteous and righteous.

Can these two be compared?

Koji raised his eyebrows and glared at him fiercely.

Frightened, Marina ducked behind Lexington, stuck out her little head and hummed and wrinkled her little nose.

"The Admiral is bullying the truth, and the truth is ignoring you...... People went to find the proprietress of the palace to replenish fuel. ”

Cute with a grimace, Marina left the Admiral and her sisters and ran away.

Veneto's eldest sister was so angry that she wanted to lose her shoes.

It's a shame that she didn't care about protecting the donkey just now, and she was kind enough to feed the poi.

"The Black Prince of Wales has appeared." The leader's self-cultivation, Sister Veneto quickly cleaned up her little mood and said.

"Huh?"

Koji raised his eyes in surprise.

"When did you find out?"

"Yesterday evening, and...... She was approaching Avalon. ”
