Chapter 891 Battery Explosion

The invention of submarines is based on the ancient Archimedes principle. Therefore, compared with surface ships, a necessary device for submarines is a water tank. By filling the water tank with water, the gravity of the submarine is increased, and it sinks.

And if you want to surface, you need to use the compressed air carried by the submarine to discharge the seawater, just like the swim bladder. During the North American Revolutionary War, the submarine was first invented, and it is still the submarine that makes the submarine shine. World Wars I and II.

Of course, the protagonist is not an island submarine.

Now, the submarine I-74 was injured by anti-submarine depth bombs. It must surface quickly, otherwise, it will never be able to surface.

Guitou Sansan was very nervous. After he learned that the stern had leaked, he immediately ordered to empty the ballast water tank in the bow of the boat.

Not all tanks are emptied, of course there is a point.

When the submarine completely enters the sea water, you can rely on the elevator to operate the various actions of the submarine, which is very similar to the aircraft. If you want to float the submarine, you need to make the boat head up.

How can we quickly make the submarine into this state? Of course, emptying the bow of the boat!

The compressed air poured into the ballast tank at the bow of the boat, and the seawater in the bow was discharged. The bow of the boat was immediately reduced in weight, while the seawater was poured in at the tail. In this way, the submarine was like a seesaw, which was naturally tilted up. !

The bow of the boat is rising rapidly, and every submariner is holding the handrail next to it tightly. This is the most crazy and exciting type of submarine operation, emergency floating!

(In later generations, Lao Mei often did this. As a result, she often collided with ships on the sea, causing several major accidents.)

The I-74 had to do this because it was flooded, and if it couldn't get up quickly, it might never get up!

The body of the boat continued to rise, and soon, the angle exceeded 30 degrees. At this time, Guitou Sansan felt that the situation was not good.

He actually forgot that there was sea water coming in from the tail!

In a normal emergency ascent, it is enough to empty the seawater at the bow of the boat, but now, there is still seawater pouring in at the rear, and the posture of the boat has changed too quickly!

When the angle exceeds 30 degrees, there will be danger!

"Quick, empty the stern ballast tank!" He gave the order quickly, but unfortunately, in the sloping hull, it is too difficult to perform such an action!

When several sailors wanted to let go of their hands, they unscrewed the valve. As soon as they let go of their hands, their bodies fell down involuntarily!

The upward angle of the hull has exceeded forty-five degrees!

On the entire submarine, the high-decibel voice of the ghostly head slammed: "Quick, empty the seawater at the tail, or we will all be finished!"

"Squeak, squeak!" Finally, a submariner reached the valve, and with all his strength, twisted it open at an angle.

The compressed air was started and injected into the ballast tank, but unfortunately, it was too late!

The rise of the hull is still continuing, and the speed is getting faster and faster!

The whole thing in the submarine fell towards the rear of the submarine. That is because the back of the submarine is low, the front is high, and the angle has reached 70 degrees, and it is still rising!

Just like a fishing float, the top is light and the bottom is heavy, and of course it stands upright!

A long submarine, originally like a fish, was swimming in the sea water, suddenly, the fish stood upright, it looked a little funny, but, to the sailors on the submarine, it meant death coming!

Submarines sail underwater, relying on battery power. This ancient lead-acid battery has been used in future generations, and is still serving battery cars and red tricycles.

This kind of battery will generate gas during charging and discharging. In order to prevent the battery from exploding due to overpressure caused by excess gas, there are ventilation holes on it. .

At the same time, this kind of battery is very heavy, so on the submarine, it is arranged at the bottom, so that the submarine is more stable.

When the submarine was erected, the battery pack was erected, and then the terrible sulfuric acid flowed out of the vent.

Yes, it is sulfuric acid! In lead-acid batteries, the electrodes are lead plates and the electrolyte is sulfuric acid!

(There is no need to worry about battery cars in future generations, because most of them are already sealed, which solves the problem of air bubbles during charging.)

The turbulent sulfuric acid formed an ocean, and in a short period of time, the partitions in the cabin were corroded, and the other end of the partitions was the terrifying seawater!

At the small hole, the sea water poured into the battery compartment and met the sulfuric acid, and a violent chemical reaction occurred. The constant bubbles rolled up and emerged, which is a large amount of hydrogen!

Then, the battery short-circuited, and a small electric spark detonated the hydrogen!

"Boom!" A huge explosion came from the direction of the battery compartment. This explosion was more violent than the explosion of a deep bomb!

In the violent explosion, the submarine I-74 was torn into two halves from the middle!

The turbulent sea water poured into the interior of the submarine along the broken opening. For each submariner, their time was calculated in seconds.

idiot!

Before the battery compartment was destroyed, the power supply to the entire submarine was interrupted, and the interior of the submarine was pitch black and turned into a cold steel coffin.

Listening to the sound used by the sea water, the ghost looked around and cursed out only one sentence.

Then, the huge sea water shrouded him.

The submarine I-74 stopped rising, broke into two halves, and continued to sink downward.

At this time, the surface ship Taylor was also rushing in. The sonar personnel on the warship heard a huge sound underwater. This kind of movement could only be caused by the explosion of the submarine!

Depth charges will not cause such a big movement. When the submarine is damaged, the torpedo carried by the submarine may explode, and this sound will occur.

Suddenly, everyone boiled, and finally killed the German submarine!

With the loud explosion, a piece of dead fish slowly floated up from under the sea water, accompanied by huge diesel oil stains, it is certain that the target has been destroyed!

"Report, an order came from the command, asking us to confirm the nationality of the target." Captain Heim, the captain of the USS Taylor, received the order.

Confirm the target nationality? Isn't it Germany? Heim looked at things floating on the sea in the distance with his telescope, very strange, and then he found something on the sea.

A floating can, look at the shell, it's not a German military can, it's completely like an island country's rice can!
