Great warships

Chapter 883 055 on the agenda
The biggest problem with this huge warship is the power system.Because there is no reliable power system, this warship has been lying down for a long time.

There are different opinions about its nuclear power system. The most representative one is that this cruiser uses a nuclear submarine reactor, which is seriously insufficient in power, so it needs an oil-fired boiler to supplement additional steam to make it reach a maximum speed of 32 knots. , otherwise it will only have a speed of twenty knots.

This kind of statement is somewhat similar to the poor Charles de Gaulle, but it is actually completely false.

When this cruiser was first designed, it was just a large nuclear-powered anti-submarine ship with a displacement of 75 tons. It was planned to be equipped with a BM4 nuclear submarine reactor with a thermal power of only 2.5 megawatts. For the 1144-ton 3-type reactor, the original reactor was simply not enough. Therefore, the relevant units specially designed a brand-new KH-300-type nuclear reactor, with a single thermal power of [-] megawatts, which has no connection with the previous nuclear reactor.

This nuclear reactor is not only installed on the Kirov class with a displacement of 2.5 tons. When the 1143.7 nuclear-powered aircraft carrier was built later, it also used a modification of this reactor, called KH-3-43, with increased thermal power. to 305 megawatts.

This is a large-scale nuclear reactor specially developed for surface ships. The Type 1144 uses two nuclear reactors to drive two steam turbines. Under full power, it can output a surging power of 14 horsepower, which is 104 megawatts. It can make the Kirov-class cruiser Soaring to a high speed of 32 knots.

(It is really a mystery how much power is needed. Our 055, with four gas turbines, also has 14 horsepower and a displacement of only 1.3 tons. How fast is the speed? Will it reach 051 knots like the 38? In short, we use eight For a gas turbine with 30 megawatts, it can reach [-] knots.)
Therefore, the nuclear power of the Kirov-class cruiser is sufficient, but the old man seems to know that his nuclear reactor is unreliable and will fail at any time, so he will have a boiler, two KGB-2 oil-fired boilers , allowing the cruiser to reach a cruising speed of 14 knots. However, the boiler is usually not activated. After all, once the fuel is installed in the nuclear power system, it would be a waste to not use it.

This kind of boiler is just a backup. In case the nuclear power system is down, it will burn the boiler to give the warship the power to continue moving forward. The two do not need to work together.

The power system of this cruiser is distributed in three compartments, one of which is equipped with a nuclear reactor, one with a boiler, and the other with a steam turbine, which is clearly organized.

The cabin containing the nuclear reactor has been completely cut open, and the nuclear reactor inside has been removed. The Geiger counter on the side only flickers occasionally, indicating that the radioactivity here is not high.It seems that although the nuclear reactor is unreliable, its safety is still guaranteed.

"Is there still a boiler here? I wonder if the boiler is also broken?" Qin Tao asked: "If the boiler is still good, it is absolutely possible to use the boiler to drive the warship."

"That's right, we thought so at the beginning, but after checking the status of the boiler, we gave up." Nicholas shook his head helplessly: "Because it has not been used for a long time, the boiler has also broken down. We also don’t have relevant boiler production units in China, so we can’t produce them as they are, and now that we have entered the era of gas turbines, it’s a bit outdated for us to burn boilers. Let’s dismantle them.”

The nuclear reactor was dismantled, but the boilers and steam turbines remained where they were. After all, these have no radiation, and it would cost money to dismantle them themselves, so they simply handed over all of them to the East.

"Okay, if these cabins are all removed, there will be no problem installing gas turbines and backup diesel engines. We will come up with a modification plan as soon as possible to complete the power conversion of this warship."

"How fast?" Nikolay asked.

"It takes one month to make a plan, and half a year to improve it."

In fact, it can be done in a month, but the modification plan worth 1000 million US dollars has increased by [-] million, how can it be done in a month?In that case, customers will feel that the money spent is not worth it!

It must be tossed slowly for half a year.

"During the time when the plan is drawn up, we will be able to derust and paint the warship's appearance. Don't worry, we are the most professional here, and we will never waste time, let alone slow down. After all, we are here There is other work on the floating dock. If there is still time, we can also conduct flaw detection on this warship to see how its hull is and whether it needs to be repaired."

Needless to say, renting a floating dock alone is not cheap.

Nicholas nodded: "Okay, then we will leave the technicians to work with you."

"Of course." Qin Tao nodded.There are many secrets on this warship. Of course, Lao Maozi will not rest assured and just throw it here. He will definitely send people to follow, so that the Orientals will not have to look at this warship inside and out.

Moreover, it is normal for the shipowner to send representatives to supervise.

So there is no other way?
Of course not, the people left by Nicholas will have hot fights with other old men within a week, isn't it normal to drink a bottle of wine after get off work?He didn't come to work the next day after drinking too much, and the warship was placed in the Mingzhou Group, which is not the meat on the chopping board of the Mingzhou Group.

When everyone came out, it was almost dark, and their stomachs were growling with hunger, so they went straight to the restaurant of the guest house, where a sumptuous dinner had been prepared.

"For our Damao Navy, today is of great significance. Our 22350 will be towed away to continue outfitting, and then become the main force of our navy. Our Admiral Lazayev will be here to undergo improvement and gain a new life Nicholas raised his glass: "Here, I would like to offer a toast to Mr. Qin of the Mingzhou Group. Without you, there would be no modernization of our navy."

Qin Tao raised his glass: "Nicholas, actually I helped you change, mainly because of our friendship for many years, and also because of our friendship between Dongfang and Da Mao. I hope our relationship will get better and better in the future. We Our friendship will last forever!"

The crowd raised their glasses and drank it all.

After drinking for three rounds, there are too many words.

"Qin, in fact, if we hand over all the modification to you, we can get the modified warship faster, what a pity..."

"Nicolas, I believe that your leaders will be able to take Da Mao to achieve economic take-off. As long as the economy improves, you will be able to build more warships, not to mention cruisers, and aircraft carriers can continue to be built." Qin Tao comforted.

"That's right, we look forward to a better tomorrow." Nicholas raised his glass firmly: "Come on, let's drink to our better tomorrow!"

Many big hairs present were actually not in a good mood. After all, they dragged the old cruiser over for refitting, and on the same pier, a modern super aircraft carrier was being outfitted. Compared with the two, they certainly have a kind Feeling depressed.

Under the same night, the 22350 frigate was towed on the road and returned to their own shipyard to start outfitting. This advanced shield ship is the hope of their navy's future.

The next day, Nicholas and his team left the Mingzhou Shipyard and embarked on the return journey. Before leaving, they looked at the Shenzhou floating dock again. The scaffolding had been set up, and the boatmen began to do basic antirust treatment , Amidst the ear-piercing sound of the grinding wheel, Nicholas and the others seem to have seen the new life of this warship, and they really hope that day will come soon.

The rising sun slowly rose into the sky from the east, shining golden sunlight on the Mingzhou Shipyard and on this land.

Not long after Nicholas and others left, Qin Tao returned to the capital, Huanglou, where a naval equipment meeting kicked off again.

"This time we saw Lao Maozi's 052-ton cruiser. It was really shocking." A naval leader said: "Our navy currently only has 052C and [-]D, which is not enough. Our navy also needs to build large warships. , This will show our naval strength and better protect the safety of our aircraft carrier."

"That's right. With the continuous development of equipment and technology, it is also necessary to increase the size of naval warships. Look at the US Navy. In addition to the Burke-class destroyers, there must be Ticonderoga-class cruisers to escort aircraft carriers. " Another leader said: "We also need to have a [-]-ton large drive, so that we can match our [-]-ton aircraft carrier. Mr. Qin, you have mentioned this plan before, and now give us a detailed introduction? "

Qin Tao sat down and looked at the leaders, a little embarrassed: "Leaders, our navy's equipment has always been tendered, and now the big guy directly asks me like this, which makes me feel a little embarrassed."

"Why are you embarrassed?" The leader said: "The bidding is just a formality. Besides you Mingzhou Group, who else has experience in the design and construction of large warships? You won't build us a [-]-ton large drive. Then who will make it?"

"That's right, I'm asking you not to be humble, but to introduce your experience. Mr. Qin, you've been developing a [-]-ton large drive for a while, so report your design quickly. Don't worry, we won't leak it. to other shipyards."

"Even if it was leaked, they don't have the technical strength."

Big guy, every word you say, and every word I say, are urging Qin Tao.

Wu Shengli smiled: "Taozi, don't be modest, the big guys are waiting, if you delay the big guys' time, everyone will have to drink you when we eat later."

"Okay, then let me explain in detail from all aspects." Qin Tao said: "Our warship must not be a simple enlarged version of 052D, it must have technological innovation."

"That's right, of course it can't be simply zoomed in, Mr. Qin, please introduce it quickly."

"First of all, our warship must adopt the latest integrated power and propulsion system of the whole ship. This method can comprehensively distribute power, has higher flexibility, and can also lay the foundation for future electromagnetic guns." Qin Tao said: " As for the specific power configuration, it can be four existing UGT-25000 gas turbines, or a combination of one UGT-40000 and two UGT-25000. We still need to go through the demonstration, and we can also look at the needs of the navy. "

If it is the 055 in the time and space before Qin Tao came, there is nothing to say, it must be four UGT25000s, but that is because ordinary drive shafts are still used for propulsion, two or even one for low speed, and four for high speed, so convenient The car is paralleled in the gearbox, but now there is the UGT-40000 with higher power and the integrated electric propulsion of the whole ship, so there are more options to choose from.

Mingzhou Group does not make a choice, they push the choice to the Navy.

"Boss Qin, what do you think is the right plan?" The naval leaders are also good people, and immediately kicked the ball back.

"From the perspective of consistency, we think the former is good. After all, the four gas turbines are the same. From the perspective of reducing the complexity of the ship's power system, we think the latter is more suitable."

Of course, Qin Tao would not do multiple-choice questions directly, but kicked the ball back.

Four identical gas turbines are more convenient to maintain. After all, one model is convenient for training, but in terms of quantity, four is not as simple as three after all. The more equipment, the greater the chance of failure.

"President Qin, can we only install two UGT-40000s?" a leader asked.

"It's not suitable, because the power will be too much when cruising, and the fuel consumption will be too high." Qin Tao said: "If the latter combination scheme is used, it is enough to use one UGT25000 for low-speed cruising, and another UGT40000 for high-speed cruising. Sailing, or when it is necessary to turn on high-power electrical equipment such as electromagnetic guns, and then start UGT-25000. Or the other two UGT-[-]."

Everyone thought about various technical solutions, and finally made a decision: "Mr. Qin, let's use four UGT-25000s."

"Why?" Qin Tao was a little surprised, he thought he would choose the two mix-and-match schemes.

"Low-speed cruise is enough to run one. We use four gas turbines, which can be started alternately, which can greatly extend the life of the power system."

At present, the navy’s warships are all powered by alternating diesel fuel. The diesel engine is turned on at low speeds, and the gas turbines are used at high speeds. Therefore, the chances of using gas turbines are not great, and the service life is also very long. They can almost have the same lifespan as warships. The reliability is very high and the service life is very long, don't worry about this.

But the transition to all-combustion power is different. Although the life of a single gas turbine has reached 20 hours, if one-third of a year is sailing at sea, it will be about [-] hours. The lifespan of an hour is also [-] years, but this refers to the entire lifespan. Among them, two overhauls are required. That is to say, the lifespan of each renovation is only [-] hours. In need of a renovation.

For the navy, it is not cost-effective for a brand-new warship to enter the dock for renovation in six years. Now, four identical gas turbines are used alternately and together in high-intensity situations, so that the renovation time can be increased to ten. 15 years, or even [-] years, it will be much more convenient. At that time, warships should also be refurbished and improved in the mid-term.

Therefore, from this point of view, it is more appropriate to have the same four sets.

Qin Tao nodded. He knew that in his original time and space, the navy chose four identical gas turbines with this consideration. They were used alternately, distributed evenly, and the interval between renovations was greatly increased.

"Okay, then four UGT25000s." Qin Tao said: "The power of a single unit is 26.7 megawatts, and the power of four units is 106.8 megawatts. According to the power of our power system, we can determine the displacement of our warship. We can and Now let’s make a comparison with other warships in the world.”

In the past, the navy wanted to build warships, but they had no suitable power, so they could only settle for the next best thing. Now, with full power, the displacement of warships can also be increased vigorously.

"Look at the DDG1000 in the United States first, using two MT-30 gas turbines and two auxiliary gas turbines, with a total power of 78 megawatts and a full-load displacement of 14560 tons. Our power system power is nearly [-] megawatts higher than it, so we It is also possible to enlarge the displacement to [-] tons by large flooding of [-] tons."

[-] tons!
Hearing this number, everyone was very excited, but Wu Shengli shook his head helplessly: "No, the displacement is too large. We will directly transition from [-] to [-] tons to [-] tons. The steps are too big, and it is easy to tear the egg. And , Taozi, you also said that the excess reserve power is reserved for electromagnetic guns and other equipment, and our displacement should not be too large."

"Yes, the larger the displacement, the higher the cost. We have to pay attention to the cost performance. If it is too expensive, we might as well make 052D." Another naval leader said.

The guys are very pragmatic.

"Then our full-load displacement is set at [-] tons?" Qin Tao asked tentatively.

"It's still a bit big, let's say [-] tons." Wu Shengli said, "Let's try to build one first, and if it doesn't meet our needs, then continue to increase the displacement."

"Oh, you guys are so careful." Qin Tao shook his head helplessly.

In fact, how powerful a warship is depends on various needs. Take the latest Arleigh Burke III-class guided missile destroyer of the U.S. Navy as an example. The ratio is the highest among the US Navy's active ships, and it is an order of magnitude compared with its own 9550 large drive. Qin Tao doesn't compare with this. In fact, he still wants to fool the navy into building a large ship. Unfortunately, the navy is timid.

If it weren't for the limited funds, do you think we don't want to build a [-]-ton destroyer?Wu Shengli gave him a blank look.

"We have a lot of power, so our warship can further reduce the aspect ratio, and have better internal space under the same displacement." Qin Tao continued, since the displacement has been determined, the other Needless to say, the data, just use the data you know.

"The length is about 180 meters and the width is about 23 meters, so the aspect ratio can be reduced to 7.8."

Can warships with the same power have the same speed?This is of course incorrect. In the past, warships were all slender, so the resistance was small. Even if the power of the power system was insufficient, it could still reach [-] knots. The power system of modern warships is getting bigger and bigger, but the power is still [-] knots. , nothing changed, what's going on?Of course, the current warships pursue comfort and reduce the aspect ratio.

Take Dongfang as an example. The early Type 051 destroyer had an aspect ratio of 10.3. At that time, it was not because of lack of power, but because it had no design experience and dared not change it. By the time of Type 052, it had a length of 148 meters and a width of 16 meters. It was reduced to 9.25, and the 052C built later has a length of 158 meters and a width of 18 meters, and the aspect ratio has been reduced to 8.6. Now, the aspect ratio of the 8-ton large drive built by our side has to be further reduced to below [-]!

(There are many different opinions about this size, and Huadong Zhixiong is the most common one. Moreover, the aspect ratio is actually only the aspect ratio of the waterline. Let’s compare the total here.)
The smaller the aspect ratio, the squarer the warship, and the larger the internal space, but at the same time, the greater the resistance and the stronger the power required.

"Well, if it's designed like this, how many weapons can it hold?" Wu Shengli asked.

"At present, we have developed a new generation of general-purpose vertical launchers, which are also used in 052D, so our latest 055 must also use this kind of vertical launcher. Eight groups can be arranged in front, and six groups can be arranged in the back. Each group has Eight launch units."

The big guy simply performed four arithmetic operations in his brain, and then reacted: "112 vertical units? Twice as many as our 052 destroyer!"

The benefits of doubling the displacement are huge.The number of missiles carried is doubled.

"It's a pity that there are not enough. The Kirov class can carry hundreds of them, and we only have more than 100." Some people are not satisfied.

"Everyone, our vertical launchers are universal. If necessary, we can have two bombs in one hole, or even four bombs in one hole." Qin Tao said: "The maximum number of bombs that can be carried is multiplied by four."

Of course, in fact, it will not be carried like this. The four bombs in one pit are all short-range missiles. The combat capability of this kind of missile is not strong, and it is a waste to carry them all.

"In normal combat, we need to match it reasonably." Qin Tao said: "We know that this set of universal hanging hair has three different lengths, namely three meters, seven meters and nine meters. Among them, the depth of the unit at the stern is all It is nine meters, and the rear launch unit of the bow can also reach nine meters, but only seven meters can be placed in the center of the front, and three meters of missiles can be placed on the front sides.”

This is entirely based on the shape of the bow. After all, the lower the ship, the narrower it becomes. Some missiles that are too long will not fit in. Of course, it is not necessary to fill all the long ones, and many of them are unnecessary.

"Overall, we have eighty nine-meter-deep pits. These pits have multi-purpose capabilities. They can launch our most advanced weapons, such as the Eagle-21 anti-ship missile, the Longjian-10 cruise Missiles, when needed, our 055 can be transformed into the main force of long-range strikes. Of course, under normal circumstances, we generally need to carry more than [-] Hongqi IX air defense missiles. After all, the main task of our escort warships is air defense."

Qin Tao introduced the purpose, if you install eighty Eagle Strike-21s, you can't scare those bastards to death!If eighty long sword ten cruise missiles are installed, those guys with ulterior motives will have to be trembling.

When there is no need for an aircraft carrier to dispatch, the 055 can play a strategic role in intimidating the enemy. It is necessary to build a [-]-ton large drive!
