Chapter 883 055 is on the agenda
The biggest problem with this huge warship is the power system. Because there is no reliable power system, this warship stays idle for a long time.
There are also 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 a fuel-fired boiler to supplement additional steam to allow it to reach a top speed of 32 knots. , otherwise it would only have a speed of twenty knots.
This statement is somewhat similar to the poor Charles de Gaulle. In fact, it is completely false.
When this cruiser was first designed, it was just a nuclear-powered large-scale anti-submarine ship with a displacement of 8,000 tons. It was planned to be equipped with a BM4 nuclear submarine reactor with a thermal power of only 75 megawatts. However, later, the project was continuously revised and eventually changed to a displacement of 8,000 tons. The original reactor of the 25,000-ton Type 1144 was simply not enough. Therefore, the relevant units specially designed a brand-new KH-3 nuclear reactor with a single thermal power of 300 megawatts, which has no connection with the previous nuclear reactors.
This nuclear reactor was not only installed on the Kirov-class with a displacement of 25,000 tons. When the Type 1143.7 nuclear-powered aircraft carrier was later built, a modification of this reactor was also used, called KH-3-43, with increased thermal power. to 305 megawatts.
This is a large nuclear reactor specially developed for surface ships. The 1144 type uses two nuclear reactors to drive two steam turbines. At full power, it can output a surging power of 140,000 horsepower, which is 104 megawatts, which can make the Kirov-class cruiser It can reach a high speed of 32 knots.
(It’s really a mystery how much power it needs. Our 055 has four gas turbines, which also have 140,000 horsepower and a displacement of only 13,000 tons. How fast is it? Will it reach 38 knots like the 051? In short, we use eight A ten-megawatt gas turbine can reach 30 knots.)
Therefore, the nuclear power of the Kirov-class cruiser is sufficient. However, Lao Maozi also seems to know that his nuclear reactor is unreliable and may malfunction at any time, so he comes with a boiler, two KGB-2 oil-fired boilers. , which can allow the cruiser to reach a cruising speed of 14 knots. However, this boiler is not usually started. After all, once the fuel is installed in the nuclear power system, it is a waste not to use it.
This kind of boiler is just a backup. If the nuclear power system fails, the boiler will be burned 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 houses the nuclear reactor, one with the boiler, and the other with the steam turbine, which is very organized.
The cabin housing the nuclear reactor has been completely cut open, and the nuclear reactor inside has been removed. The Geiger counter on the side only flashes occasionally, indicating that the radioactivity here is not high. It seems that although nuclear reactors are unreliable, their safety is still guaranteed.
"Is there a boiler here? I wonder if the boiler is broken?" Qin Tao asked: "If the boiler is still good, the boiler can be used to drive the warship."
"Yes, we thought so at the beginning, but after checking the status of the boiler, we gave up." Nicholas shook his head helplessly: "Due to long-term use, the boiler has also broken down. At present, We don’t have relevant boiler production units in the country, so we can’t produce them as they are. Moreover, now that we have entered the era of gas turbines, it is a bit outdated for us to burn boilers anymore. Let’s dismantle them.”
The nuclear reactor was dismantled, but the boiler and steam turbine remained in place. After all, there was no radiation in these. If they dismantled them themselves, they would have to spend money, so they might as well leave them all to the East.
"Okay, if these cabins are dismantled, there will be no problem in installing the gas turbine and backup diesel engine. We will come up with a modification plan as soon as possible to complete the power modification of this warship."
“How fast?” Nicholas asked.
“It takes one month to come up with a plan and half a year to improve it.”
Actually, it can be completed in one month. However, a modification plan worth 100 million US dollars has increased to 10 million US dollars. How can it be completed in one month? If that is the case, the customer will feel that the money is not worth it!
It has to be done slowly for half a year.
"During the time when the plan is drawn up, we will be able to carry out exterior rust removal and painting operations on this warship. Don't worry, we are the most professional here and will never waste time or be passive in work. After all, we are here There are other tasks on the floating dock. If there is still time, we can also conduct flaw detection on the warship to see what the condition of its hull is and whether it needs repair."
Needless to say, renting a floating dock alone is not cheap.
Nicholas nodded: "Okay, then we will leave the technical staff to work with you."
“Of course.” Qin Tao nodded. There are many secrets on this warship. Of course, Lao Maozi will not just throw it here without worry. He will definitely send personnel to follow it to save the Easterners from having to see the warship inside and out.
Furthermore, it is normal for shipowners to send representatives for supervision.
Then there is no other way?
Of course not. The people Nikolai left behind would be fighting with other old men within a week. Isn't it normal to have a bottle of wine after get off work? I drank too much and didn't come to work the next day. The warship was placed on the Mingzhou Group. It was not meat on the Mingzhou Group's chopping board.
When everyone came out, it was almost dark, and their stomachs were growling with hunger. They went straight to the guest house restaurant, where a sumptuous dinner had been prepared.
"Today is of great significance to our navy. Our 22350 will be towed away to continue outfitting, and will later become the main force of our navy. Our Admiral Razaev will be improved here and given a new life. ." Nicholas raised his glass: "Here, I would like to toast Mr. Qin of Mingzhou Group. Without you, there would be no modernization of our navy."
Qin Tao raised his glass: "Nicola, in fact, I helped you make changes mainly because of our many years of friendship, as well as our friendship between Dongfang and Damao. I hope our relationship will get better and better in the future. Our friendship will last forever!"
Everyone raised their glasses and drank it all in one gulp.
After three rounds of drinking, I talked a lot.
“Qin, if we leave all the modifications to you, we can get the modified warships faster, but it’s a pity..."
“Nicholas, I believe that your leader will be able to bring Da Mao to economic take-off. As long as the economy improves, you will be able to build more warships, not to mention cruisers and aircraft carriers.” Qin Tao consoled him.
“Yes, we look forward to a better tomorrow.” Nicholas raised his glass firmly: “Come, let’s drink to our better tomorrow!”
Many of the big guys present were actually not in a good mood. After all, they were dragging old cruisers over for refitting, and on the same pier, a modern super aircraft carrier was being outfitted. Compared with the two, they certainly felt a little uncomfortable. Feeling depressed and unhappy.
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 for the future of their navy.
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 erected and the shipwrights began to do basic anti-rust treatment. , amidst the harsh sound of hand grinding wheels, Nicholas and others seemed to see the new life of this warship, and they really hoped that day would come soon.
The morning sun slowly rises into the sky from the east, shining golden sunlight on the Mingzhou Shipyard and the land.
Soon after Nicholas and others left, Qin Tao returned to the capital, Huanglou, and a naval equipment meeting kicked off again.
"This time we saw Lao Maozi's 25,000-ton cruiser. It was really shocking." A naval leader said: "Our navy currently only has 052C and 052D. This is not enough. Our navy also needs to build large warships." , This can show our naval strength and better protect the safety of our aircraft carrier."
"Yes, with the continuous development of equipment technology, it is also necessary to increase the size of naval warships. Look at the U.S. Navy. In addition to the Burke-class destroyers, the aircraft carriers must also have Ticonderoga-class cruisers. ." Another leader said: "We also need to have a 10,000-ton large drive, so that it can match our 80,000-ton aircraft carrier. Mr. Qin, you have mentioned this plan before. Now give us a detailed introduction? "
Qin Tao sat below and looked at the leaders, feeling a little embarrassed: "Dear leaders, our navy's equipment has always been subject to bidding. Now that you guys are asking me directly like this, I feel a little embarrassed."
"Why are you so embarrassed?" The leader said: "The bidding is just a formality. Apart from your Mingzhou Group, who else has experience in the design and construction of large warships? If you don't build a 10,000-ton cruise ship for us, Then who will make it?”
"That's right, I'm not asking you to come here to be modest. I want you to introduce your experience. Mr. Qin, you have been developing a 10,000-ton drive for some time. Please report your design plan as soon as possible. Don't worry, we will not leak it. For other shipyards.”
“Even if it’s leaked, they don’t have the technical strength.”
Every word from you or me is urging Qin Tao.
Wu Shengli smiled: "Taozi, don't be modest. Everyone is waiting. If you waste everyone's time again, then everyone will have to drink from you during the meal."
“That’s right, of course it can’t be a simple enlargement. Mr. Qin, please introduce it quickly.”
"First of all, our warship must adopt the latest integrated power and propulsion system for the entire 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 combination, it can be four existing UGT-25000 gas turbines, or a combination of one UGT-40000 and two UGT-25000. We still need to further demonstrate this, and it can also depend on the needs of the navy. "
If it were 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 transmission shafts are still used for propulsion. Two or even one is used for low speed, and four is used for high speed. This is convenient. The vehicles are paralleled in the gearbox, but now there is the more powerful UGT-40000 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.
“Mr. Qin, what kind of plan do you think is suitable?” The leaders of the navy were also smart people and kicked the ball back immediately.
“From the perspective of consistency, we think the former is beneficial, after all, the four gas turbines are the same, and from the perspective of reducing the complexity of the entire ship’s power system, we think the latter is more appropriate.”
Of course, Qin Tao would not answer the multiple-choice questions directly, but kicked the ball back.
Four identical gas turbines are more convenient to maintain. After all, they are one model and easy to train. However, in terms of quantity, four units are not as simple as three units. The more equipment there is, the greater the chance of failure.
“Mr. Qin, can we only install two UGT-40000s?” a leader said.
"It's not suitable. This way, there will be excess power when cruising, and the fuel consumption will be too high." Qin Tao said: "If we use the latter combination plan, it is enough to turn on one UGT25000 for low-speed cruising, and turn on another UGT25000 for high-speed cruising. During navigation, or when you need to turn on high-power electrical equipment such as electromagnetic guns, start UGT-40000 or the other two UGT-25000."
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 a mix and match of the two options.
“One gas turbine is enough for low-speed cruising. We use four gas turbines, which can be switched on alternately. This can greatly extend the life of the power system.”
At present, the navy's warships use alternating diesel power. The diesel engine is turned on at low speeds and the gas turbine is used at high speeds. Therefore, the use opportunities of gas turbines are not large, and their service life is also very long. They can almost have the same lifespan as warships. As for diesel engines, originally The reliability is very high and the lifespan is very long, so there is no need to worry about this.
But the transition to full-combustion power is different. Although the life of a single gas turbine has reached 60,000 hours, if one-third of the year is spent sailing at sea, it will be about 3,000 hours. This 60,000 hours The service life of an hour is also twenty years, but this refers to the entire life. Among them, it needs to undergo two major overhauls. In other words, the service life of each overhaul is only 20,000 hours. In normal use, it will be six years. Just needs a renovation.
For the Navy, it is not cost-effective for a brand-new warship to be renovated in the dock every six years. Now, four identical gas turbines are used alternately and together under high-intensity conditions, so that the renovation time can be increased to ten Years, or even fifteen years, would be much more convenient. By that time, the warships would be due for mid-term renovations.
So, from this perspective, it is more appropriate to have four identical units.
Qin Tao nodded. He knew that in his original time and space, the Navy also had this consideration in choosing four identical gas turbines. They were used alternately and evenly distributed, and the overhaul interval was greatly increased.
"Okay, then four UGT25000s." Qin Tao said: "A single unit has a power of 26.7 megawatts, and four units are 106.8 megawatts. Based on the power of our power system, we can determine the displacement of our warship. We can and Now let’s compare it with other international warships.”
In the past, the navy wanted to build warships, but without suitable power, it had to settle for the next best thing. But now, with sufficient power, the displacement of warships can be greatly increased.
"Let's first look at the American DDG1000, which uses two MT-30 gas turbines and two auxiliary gas turbines, with a total power of 78 megawatts and a full load displacement of 14,560 tons. The power of our power system is nearly 30 megawatts higher than it, so we It is also possible to use a 10,000-ton large-scale drive to enlarge the displacement to 20,000 tons.”
Twenty thousand tons!
Everyone was very excited when they heard this figure, but Wu Shengli shook his head helplessly: "No, the displacement is too big. Let's directly transition from seven or eight thousand tons to twenty thousand tons. The step is too big and it is easy to tear the eggs. Moreover, , Taozi, you also said that the excess reserve power is reserved for equipment such as electromagnetic guns, and our displacement cannot be too large."
“Yes, the larger the displacement, the higher the cost. We have to pay attention to cost-effectiveness. If it is too expensive, we might as well build 052D.” Another naval leader said.
Everyone is very pragmatic.
“Then our full load displacement is set at 15,000 tons?” Qin Tao asked tentatively.
"It's still a bit big, just 13,000 tons." Wu Shengli said: "Let's build one first and try it out. If it doesn't meet our needs, we can continue to increase the displacement."
“Alas, you are so careful.” Qin Tao shook his head helplessly.
In fact, the power of a warship depends on various needs. Take the U.S. Navy's latest Arleigh Burke III-class guided missile destroyer, which has a full load displacement of 9,550 tons and uses four LM2500 gas turbines with a total power of 75 megawatts. The ratio is the highest among the active ships of the U.S. Navy, and it is on the same order of magnitude as our own 055 large-scale cruiser. Qin Tao does not use this as a comparison. In fact, he still wants to fool the navy into building a big ship, but it is a pity that the navy is timid.
If funds weren't limited, do you think we wouldn't want to build a 20,000-ton destroyer? Wu Shengli rolled his eyes at him.
"We have full power, so our warship can further reduce the aspect ratio and have better internal space with the same displacement." Qin Tao continued to introduce, now that the displacement has been determined, then other Needless to say about 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.”
With the same power, can warships 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 system was insufficient, they could still reach 30 knots. Modern warships’ power systems are getting larger and larger, but the power is still 30 knots. , hasn’t changed much, what’s going on? Of course, today's 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. It was not because of lack of power at the time, but because it had no design experience and did not dare to change it. By the time it was Type 052, the length was 148 meters and the width was 16 meters. It was reduced to 9.25. The later 052C was built with a length of 158 meters and a width of 18 meters. The aspect ratio was reduced to 8.6. Now, the aspect ratio of the 10,000-ton large drive built by our own side is further reduced to less than 8!
(There are many different versions of this size, and the one adopted by East China Heroes is the most common one. Moreover, when talking about the aspect ratio, the aspect ratio of the waterline is actually useful. Let’s compare it here.)
The smaller the aspect ratio, the squarer the warship will be, and the larger the internal space will naturally be. However, at the same time, the greater the resistance it will receive, and the stronger the power it will need.
“Well, if it is designed like this, how many weapons can it hold?” Wu Shengli asked.
"At present, we have developed a new generation of universal vertical launch devices, which are also used on 052D, so our latest 055 must also use this kind of vertical launch unit. Eight groups can be arranged in the front and six groups in the back. Each group has Eight launch units.”
The guys simply performed four arithmetic operations in their brains, and then reacted: "112 vertical hair units? That's twice as many as our 052 destroyer!"
The benefits of doubling the displacement are huge. The number of missiles carried has doubled.
“It’s a pity that there are not enough. The Kirov-class can carry hundreds of missiles, but we only have more than a hundred.” Some people are not satisfied.
"Everyone, our vertical hair is universal. If necessary, it can be loaded with two bombs in one pit, or even four bombs in one pit." Qin Tao said: "The maximum number of weapons can be multiplied by four."
Of course, it will not actually 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 hair extensions 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 at the bow can also reach nine meters, but only seven meters of missiles can be placed in the front and center, and three meters of missiles can be placed on both sides of the front."
This is completely based on the shape of the bow. After all, the lower it is, the narrower it becomes. Some missiles that are too long cannot be stuffed in. Of course, it is not necessary to stuff all the long missiles. Many of them are not needed.
"In total, we have eighty nine-meter-deep pits. These pits have multi-purpose capabilities. They can launch our most advanced weapons, such as YJ-21 anti-ship missiles and Changjian-10 cruise missiles. 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 fifty Hongqi-9 air defense missiles. After all, the main task of our **** warships is still air defense."
Qin Tao introduced the use. If eighty Eagle Strike-21s were installed, those **** would be frightened to death! If eighty Changjian 10 cruise missiles were installed, those guys with ulterior motives would still be wary.
When the aircraft carrier is not needed, the 055 can play a strategic role in intimidating the enemy. It is necessary to build a 10,000-ton cruiser!
