Great warships

In the era of burning boilers, it takes a long time to start the main engine, and nuclear power is no exception. Nuclear power still burns boilers, but without coal and oil, but the start-up of gas turbines is very fast, and after starting , reaching maximum power very quickly.

The whistling sound of the gas turbine came from the tail, and light blue smoke came out of the chimney of the Admiral Zaraev again, and the entire hull trembled, as if excited about being reborn.

"Report, both hosts have been activated!"

"Two cars, one forward!"

When the floating dock put down the warship, it had already turned its direction, and the bow of the ship was facing outward. At this time, following the command, the surging power was transmitted to the motor, and the motor drove the propeller to rotate. Amidst the sound of clattering water, Relying on its own power, the huge ship started to move again!
When it came, it was dragged by a tugboat, and when it went back, it could already use its own power!
All are excited.

"Can this warship be reversed?" Someone suddenly asked.

This is a simple question, but also a crucial one.

How does the warship reverse?

It depends on the structure of the main engine. If the main engine can be reversed, this is the most convenient. If the main engine is reversed directly, the propeller can be reversed. The steam turbine can be realized by setting the reverse turbine blades, and even some marine diesel engines can also be reversed. You can play like this, the drive shaft of the low-speed diesel engine is directly connected to the propeller, there is no gearbox in the middle, and if you want to reverse, you can only reverse the diesel engine.

If the main engine cannot be reversed, it will be troublesome. You need to add a reverse gear in the gearbox, just like the reverse of a car. If you use a variable-pitch propeller, you can reverse the deflection direction of the propeller blades, which can also be achieved. The purpose of reversing.

This [-]-ton giant ship uses a gas turbine, but it is not directly driven by the gas turbine, but electric drive. How can it be reversed?

"This is simple. When reversing, just reverse the input current of the motor."

The DC motor is to adjust the positive and negative poles, and the three-phase asynchronous motor is to adjust two of the phases, which can meet the requirements of direct inversion, and the inversion of the motor is too simple.

"Oh."

"Do we need testing now?"

"No, the most important thing for us is to test the speed." Nikolai said: "Keep increasing the speed!"

The huge hull speeded up and drove towards the sea. When it left the river and came to the sea, Nicholas impatiently issued an order: "Two cars, move forward five!"

The gas turbine rotates at high speed, and the power of [-] megawatts is transmitted to the high-efficiency generator at the rear. The electric energy generated by the generator surges into the four driving motors at the rear, each driving motor is [-] megawatts, two Connected in series to drive a propeller.

The speed of the propellers increased, and the huge warship also accelerated.

Fifteen, twenty, twenty-five, thirty!

"Report, the speed has reached thirty knots!"

"Okay, that's great. Our cruiser is finally resurrected with full health!" Nicholas was very excited: "The sea trial is over, and I declare that this warship has met the delivery requirements!"

Is this the end?
Sea trials are scientific and rigorous!
On the side of Mingzhou Group, there is a set of standard procedures for sea trials, but this is not the case with Lao Maozi. The delivery of warships by Lao Maozi has always been careless. On the line, check item by item?Isn't that suspicious of the shipyard?The shipyards are not used to the navy.

In the previous era, Lao Maozi's shipyard was still very domineering. Of course, they also have domineering capital. They can pat their chests and guarantee that the warships we build ourselves will be fine!

Since the collapse of the Red Empire, Lao Maozi's navy has not received brand new warships, so they have not changed the rules.

This sea test is just a test in the sea. It's no big deal. Don't they believe in Mingzhou Group?
Moreover, this warship has changed only one power system, and nothing else has been changed, and there is nothing to test.

There was bursts of applause from the side, and the other old men were also very excited. This warship can sail back!
How powerful the Pacific Fleet used to be, with two heavy-duty aircraft-carrying cruisers supporting the facade, and coordinating with other large and small warships, the devils were so scared that they wrote a Minsk attack. What about now?In the current Pacific Fleet, there is only one Glory class with a displacement of [-] tons left to support the facade. The Damao Navy has declined to such an extent, and it is urgent to restore its former glory.

When the Admiral Zaraev enters service, they can immediately change their naval shotguns, double the displacement of their main warship, and more than double the number of missiles they carry. I don't know, but at least it can be used to scare people.

They were too anxious, since it had been repaired, they drove back to the town as soon as possible.As for the changes to the upper electronics?That ship No. 22350 has not been repaired yet, and this one is not in a hurry.

"Okay, then on behalf of the Mingzhou Group, congratulations on the new life of your old ship!"

The whole sea trial process lasted for an hour. After everyone came ashore, Nicholas and others signed the delivery documents. Next, the sailors boarded the ship and received training. Nicholas and others came to the guest house restaurant.

"Come on, let's raise our glasses and thank Mingzhou Group for remodeling an old ship for us. If it wasn't for Mingzhou Group, this warship would probably have been abandoned." Nicholas raised his glass.

"These are what we should do. You need a strong navy to restore its former glory. The remaining ships are welcome to be sent to us for modification at any time." Qin Tao raised his wine glass and said.

"That's for sure. After we go back, we will advise our superiors." Nicholas said: "Our three major fleets all need to have such powerful warships, especially the Northern Fleet, which needs two Type 1144 aircraft carriers to escort us." , Speaking of aircraft carriers, yours has already undergone sea trials, what's the result of the sea trials?"

"The result is very good. The sea trial went well. It is estimated that he will enter active service in the navy soon." Qin Tao said.

"You have a nice carrier! If only we could order one."

"Yes, our own shipbuilding industry is too bad. After the 22350 warship returned, it has been soaking in the water, and there is no way to install various equipment in time."

Listening to these people's words, Qin Tao also felt emotional. The old man has declined, and their shipbuilding industry can't meet the needs of the navy. Even if the shell is built for them, it will be very difficult for them to install various equipment. Slowly, without ten or eight years, the outfitting of the 22350 ship could not be completed.

However, if the old man is not allowed to try it, they probably won't give up and leave it to their own side for outfitting. After all, they are not of one mind with their own side, and it is impossible to trust their side unconditionally.

"For your side, what you need most is an amphibious assault ship. At present, we have begun to manufacture this kind of warship for customers. If you need it, you can order it from us." Qin Tao began to flicker.

Although Lao Maozi is down and out, he still has a certain ability, otherwise he would not order two Northwest winds from France. Now that the relationship between the big guys is so good, of course the French can't take advantage of this. Qin Tao believes that as long as he works hard Deep, the iron pestle is ground into a needle, the old man will be tempted sooner or later.Every time I see Lao Maozi, I will fool them with this.

"Amphibious assault ships cannot take off and land conventional fighter jets. It would be great if they were equipped with catapults." Some people began to make requests. With catapults installed, more advanced fighter jets could be taken off and landed.

"If you don't have a catapult, you can change it to a jumping deck."

"Guys, I'm talking about amphibious assault ships, not aircraft carriers."

Qin Tao eloquently introduced the difference between an amphibious assault ship and an aircraft carrier, and he was fooling around while introducing.Many people were tempted.

The night was getting darker and darker, and the drunk Lao Maozi was sent to his room to rest. Inside the warship docked on the dock, there was a group of people listening to the introduction of the technical staff.

In fact, the operation of gas turbines is very simple. After all, there is no need to turn on the boiler or observe various pressure gauges. This kind of gas turbine is not very bad, and its life is still very long.

"The key is the fuel. Our gas turbines burn diesel. Don't mix other fuels, otherwise there will be big problems."

Gas turbines can use various fuels, the best being aviation kerosene. After all, gas turbines are similar to aviation engines, but they are too expensive, so they can only be modified. Diesel is the most common fuel, and the supply is also very convenient.

"Isn't heavy oil okay?"

"Of course not, absolutely not. We have installed special diesel fuel tanks on this warship. If you switch to heavy fuel oil, then this warship will be scrapped."

Heavy oil is the cheapest fuel, but it also has many disadvantages. It is better not to touch marine gas turbines.

Unknowingly, the eastern sky gradually brightened.

Stanislav stood on the bridge, filled with emotion.

"Back then, when we parked this warship on the pier and extinguished the nuclear reactor, we never thought that it would be reborn again." Stanislav said: "Today, this warship is finally going to set sail again. It has witnessed The strength of the Red Empire, our decline after the collapse, now, it will witness the rise of our big hair navy! Now, let us bring this warship home!"

Stanislav used to be the captain of this warship and personally issued the order to shut down and seal it. After that, how many times did he expect that this warship could be renovated and put into service, and how many times he was disappointed. Now, Stanislav still feels It's like a dream.

He looked towards the port, where a large number of high-ranking naval officials were seeing off.Looking at the warship, they were also full of emotions.

"Thanks to the Mingzhou Group, otherwise this warship would never be reborn." Nicholas sighed again.

"We just did what we were supposed to do, and I wish you all the best of luck."

"Woo, woo!" The whistle sounded, and the huge warship slowly left the port with the help of several tugboats.

"Salute!" Nicholas shouted, and all the old-haired officers raised their hands to salute the huge warship and watched it leave.

"It's so exciting. We will fly back to Vladivostok to receive the warship and hold a grand commissioning ceremony." Nicholas said excitedly: "Qin, we will be here soon." Goodbye, do you want to come with us?"

"Not yet." Qin Tao shook his head: "We still have a lot of things waiting for me here."

Qin Tao indeed still has a lot of work to do. The aircraft carrier has already undergone sea trials. How can we do without a special supply ship?The last time I ran into Peace Pigeon No. [-] at sea, I should go and have a look. There are many things waiting for me, but I can't go to Da Mao for a trip. The key is that Da Mao doesn't have any good things now.

"Okay, then please get ready to receive our other warships of the same type."

The Admiral Zaraev sailed into the sea, all the way north, Stanislav said excitedly: "Ready to turn on the radar!"

"Which radar is turned on?" the subordinate asked.

"The MR750 radar, of course," said Stanislav.

They will definitely receive a lot of attention when they go back this way. There will be many planes to observe along the way. They have to be prepared, so they must turn on the radar.

On the auxiliary mast of this kind of warship, there is an MR750 radar, which is code-named roof in the West. Yes, it is the search radar commonly used on the modern class. The performance of this radar is still very good, and it can fully meet daily use.

"Understood, turn on MR750."

Many of the sailors who came to receive it were sailors who had operated this warship before. They were fairly familiar with this warship, so they could get started directly.

The passwords were sent out one by one, but the radar soldiers did not see any images appear on the screen.

"Report, MR750 radar failure."

"Immediately fix the fault, and hope not to burn the tube, otherwise we can only turn on the MR800."

The sailors climbed into the rear jib mast and began to check the radar equipment. Soon, the news was reported.

"It is reported that the cable leading to the radar antenna was bitten off by a mouse, and a lot of mouse droppings were found at the scene."

"Damn mouse." Stanislav gritted his teeth: "It seems that we can only turn on the main radar, start MR800!"

The highest position of the entire warship, that is, the top of the main mast, is installed with this kind of MR800 radar, which is code-named top pair in the west. This radar is composed of two antennas, one is an orange slice placed horizontally, and the other is a watermelon placed vertically Skin.

This radar is composed of MR600, which is the three-coordinate long-range air search radar code-named Dingfan in the West, and MR-500, a two-coordinate radar code-named Dingwang in the West. It is mainly used for long-range early warning.

Relying on its powerful power, this kind of radar has a search range of more than 500 kilometers. Even a target the size of a fighter jet can reach a search distance of [-] kilometers. And because of its high power, it will hardly be interfered.

However, this kind of radar also has many flaws. For example, the short-distance search capability is seriously insufficient, so a top plate is needed to make up for leaks. Moreover, it consumes a lot of power, so it is usually not dared to open it.

This time they went back, they only planned to open a top panel, but the top panel was broken, and there was no backup cable, so they had to open the top pair of radars.

"Understood, turn on the flag radar!" The man flipped a switch, and huge current surged to the radar components. The next moment, a burning smell spread into the bridge.

"Where is the fire?" Stanislav shouted: "Quick, find the fire and put it out as soon as possible!"

For warships, catching fire is a terrible thing, and it is possible to burn the entire warship. Such tragedies usually happen during the construction or renovation of warships, but if you are unlucky, it will also happen during the voyage.

At this time, everyone became nervous, and soon, someone shouted on the radio: "Report, smoke is found on the main mast!"

Smoke from the mainmast?
Stanislav suddenly thought of something: "Damn it, our radar is on fire, quickly, turn off the radar!"

Since the mouse bites the MR750, of course it can also bite the MR800, and even damage many circuits, but the MR800 has the highest power, so if it is bitten, the short circuit will immediately catch fire!
You can't see it from the inside of the bridge, but you can only see it from the deck or the top of the bridge. After all, the Kirov-class cruiser is too big, so its main mast is far behind the bridge. , the top of the bridge is flat.When Stanislav hurriedly climbed out of the bridge and stood on the roof to look behind, not only was the smoke and dust billowing from the mast, but also a lot of flames had burst out. These flames went down and began to sweep other white balls. But they are all kinds of radar or satellite dishes.

Stanislav was shocked.

"Hurry up, put out the fire, put out the fire immediately, what about the damage control? Hurry up!"

The fire hose was pulled out, but when it was turned on, no water came out of it.

"Quick, fix the firefighting equipment!"

For the sailors on this warship, this was the saddest moment. They went from peak to trough in just half an hour. At this time, the warship had just headed north when such an accident occurred.

Seeing that the fire-fighting facilities on the warship could not be used, Stanislav thought of something in despair: "Quickly, contact Mingzhou Group immediately and ask them to help put out the fire!"

Ten minutes later, a fire-fighting boat came out from a nearby port, and fire hoses flocked here, one after another, in short bursts.

"Tell them we've cut off the power and they don't have to worry about electrocution!"

Water can extinguish fire, but can it extinguish electrical fire?The answer is yes, this is a short spray. Before the water reaches the flame, it is already at a safe distance from the fire sprinkler here, so it will be fine.

The fire hose sprayed out a continuous flow of water. After 3 minutes, the flame was finally extinguished. However, the entire mast was completely destroyed. Looking at the charred equipment, Stanislav wanted to cry without tears.

On the Mingzhou Group side, Nicholas and others who were about to leave were also completely dumbfounded.
