Great warships

The Arctic route, along the way, is at the door of Lao Maozi's house.

Therefore, what you want to do is very simple. Of course, whether these practices will make Europeans unhappy, then I don’t know.

4 month 1 day.

The only 052B frigate No. 167 and No. 615 comprehensive supply ship sounded their whistles and slowly sailed out of the port. Under the eyes of countless people seeing off, they embarked on the route to Europe.

Many media also reported on this, but when the warship went to sea, it seemed to have lost its trace.

"What's the matter with the Orientals? Are they lost?" The first stop of the visit was Germany, and Schroeder, the naval leader in charge of the reception, said curiously: "Since they went out to sea, the reconnaissance satellites have been unable to find them. ?”

"Yes, we are also very curious. The Pentagon is currently helping us find it, and it is estimated that we will find something soon."

This time they invited the warships from the East to visit for a variety of purposes, and they will definitely not be as friendly as they seem on the surface.

If you want to attack a fleet, you must first discover its existence. Even if it is an aircraft carrier formation, it will appear very small on the rippling ocean. It is very difficult for reconnaissance satellites to find it.

However, after the target left the port, it was lost overnight, which has never happened before.

"Report, the target has been found!" Just then, someone pushed the door open.

"Arnold, where are they?" Schroeder asked.

"They're heading in the direction of Kamchatka."

"What? Kamchatka Peninsula? What are they doing there?" Schroeder immediately became curious.

"If they didn't lose their way, then they probably planned to take another route," Arnold said.

"The North Pole route?" Schroeder's face was a bit ugly: "They actually want to take this route? Even if they come to visit us in Europe, they want to promote it to the old man? Damn it, they are clearly despising us!"

Schroeder was having a hard time.

"Yeah, and even though they sent the Aegis battleship, it's not the 052C we want to see, but 052B. There is only one warship in their equipment sequence. It is obviously a failure. They are too No sincerity!" Arnold continued.

The big guys all came here for 052C, but in the end they took off everything, so you just show this to yourself?

There was no sincerity in the whole process, but now they can't say anything.

After all, Xiaodun is also a shield, can they despise it?Their own F-124 is also this kind of small shield.

No matter what Europeans do, they are very procrastinating, because they have no money, they tend to joint research and development, but because of various needs, the research and development will fail in the end, and finally they have to build it themselves.

After some delays, Germany's new generation of Saxon-class frigates has finally completed the design and started construction to replace the three Lütjens-class destroyers purchased from the United States in the 60s, code-named F-124 frigate Although it is called a frigate, it has a displacement of more than 6000 tons. It has many similarities with the 052B that visited this time. For example, they all have four small shields fixed on the highest mast of the whole ship.

It's just that their frigates have not yet officially entered service.

虽然建造合同在96年就正式签署，但是第一艘军舰萨克森号到了99年2月1日才开始安放龙骨，计划在01年下水，02年底交付海军。

It was precisely because their own warship started construction that Rainbow Nation had the confidence to place an order. As a result, the order was still yellow. After they discovered the problem with the chimney, they urgently checked the design of their own warship, and they were shocked , Well, my own F-124 also has this kind of problem. Fortunately, the chimney has not been built yet, and it can be remedied in time.

However, they were lucky enough to feel a little ashamed. Could it be that their own technology has really been surpassed by Dongfang?
"Huh, everyone thinks that the big hair is the biggest threat. In fact, the threat from the Orientals will be even greater. Unfortunately, many people are short-sighted and can't see this." Schroeder said with some emotion: "This time, wait until When the warships of the Easterners arrive, we must take a closer look inside and out, to see how their warships are different from ours, and what are the defects."

At this time, they were still harboring fantasies. After all, the purpose of inviting the warships from the East was to see the equipment of the other warships.

"Our warships are of course the most advanced, especially our power system, which uses the world's most advanced CODAG method. The Orientals still have a long way to go in this regard. Speaking of industrial background, they still have too poor."

Speaking of the comparison of warships, Arnold became excited again.

Also commenting, there is Zhang Zhong said the show.

Each episode must have something to attract attention. The Kirov-class arsenal ship in the last episode made Zhang Zhong said that the ratings of the show once again created a miracle, and this episode is also highly anticipated.

"We know that the first stop of the formation's visit is Germany. Germany's most advanced warship, the F-124, is very similar to our 052B, with small shields on all sides and a large shield rotating behind it. I think it is for this reason that the navy We decided to send No. 167 there. In today’s program, let us compare the two warships. However, we decided to compare the power first. The power system of the F-124 still has many unique features.”

"We know that in order to make warships have good reliability on the battlefield, warships generally need a power arrangement with two oars and two rudders, so that even if one group is lying down, the other group can drive the warship to continue to move. F- The 124 also uses twin propellers, but its transmission system is very complicated, and it has a unique transmission gearbox."

A structural diagram appeared on the screen, showing the characteristics of the power system of the F-124 frigate.

"Generally speaking, in a common diesel-fuel alternating system, a diesel engine and a gas turbine are connected with a set of gearboxes. During normal operation, only one can transmit power. This is mainly because one or two thousand It is difficult to match a diesel engine with tens of thousands of revolutions and a gas turbine with tens of thousands of revolutions. However, the German F-124 frigate is different. It can be coordinated through a special gear set so that the diesel engine and the gas turbine can work at the same time, and even derived Unique transmission mode."

The F-124 uses a unique transmission system, and also has a unique propulsion mode: the gas turbine drives two propellers at the same time, or the gas turbine drives one and the other is driven by two diesel engines, even when economical cruise is required. With only one diesel engine driving two propellers, the combination is dazzling and looks very advanced.

"This method has great disadvantages. Once the transmission gearbox is damaged, the entire ship will lose power completely. After all, its power system is not separated, but combined. We have reason to believe that there is no way After all, there is only one LM2500 gas turbine on this warship with a displacement of [-] tons. Considering the cost factor, the Germans are not willing to use two gas turbines, so they can only find a way on the transmission system."

When watching this episode, Schroeder almost vomited blood.

When Germany sells frigates abroad, it has always introduced this power system as a feature. Looking at the world, only Germany can allow gas turbines and diesel engines to work together!This is a manifestation of our technology. How come it is said by the Orientals that we are short of money and cannot afford two gas turbines?

Even if it's really to save money, you can't say that, isn't this throwing dirty water?Ignore our advanced technology, only focus on our lack of funds, hateful, too hateful!
Schroeder was furious.

"They are envious and jealous. Their diesel engines and gas turbines cannot work at the same time. This is a waste." Arnold also spoke aside.

Normally, only one type of diesel-burning alternating power can be used. For warships, this is undoubtedly quite wasteful. Orientals do not have this technology, so they are envious and jealous!

On the TV, Zhang Zhong continued to introduce: "Except for the F124, almost all other warships are diesel-fueled or fuel-fueled alternately. This will indeed cause some waste. Only one set of engines can be used, and the other set of engines is always In the idle state. However, with the development of technology, this shortcoming will soon be made up, and this technology is all-electric propulsion."

When they heard this statement, both Schroeder and Arnold were stunned, ah yes, if it is all-electric propulsion, it doesn't need to be so complicated, and it seems that Dongfang already has this kind of technology!
"It is very difficult to connect engines with different characteristics to output power in parallel, but if it is converted into electrical energy, it can output energy very conveniently. Therefore, the integrated power system of the whole ship has become a trend. Especially the electric propulsion of the whole ship , This will completely solve the problem of the transmission system, no need for a reduction gearbox, no need for a transmission shaft, as long as the power is output to the electric motor at the tail of the warship, whether it is a gas turbine or a diesel engine, both are used to generate electricity, so the system is redundant The speed is also high, and the whole ship will not lose power due to the damage of the gearbox. We predict that in the future, all warships will popularize the integrated electric power and propulsion system of the whole ship."

"Let's take the East as an example. Now a warship with a displacement of [-] tons uses two gas turbines and two diesel engines. In the future, it is completely possible to use a [-]-megawatt gas turbine and two diesel engines. It meets the power requirements of the whole ship, and all the engines are placed under the chimney instead of at the tail of the warship, which can make the layout of the warship simpler. Here, we also expect the Germans to develop similar technology, and I cheer for you!"

come on?Who the hell needs your help?You are clearly despising us!

East.

"Come on, Zhang Zhong, cheers, you've done a really good job on this episode!" Qin Tao raised his glass and said, "Be the first to win, our warships have not even arrived in Europe yet, so let's compare them!"

"President Qin, this is what I should do." Zhang Zhong said: "Besides, these ideas are all given by you, and I just announced them."

"No, this has nothing to do with me. Zhang Zhong said that the program is independently operated." Qin Tao said, "This is a program named after you, and it has nothing to do with our Mingzhou Group."

"Yes, it has nothing to do with Mingzhou Group." Zhang Zhong nodded: "President Qin, we decided to talk about Type 45 destroyers in the next issue. What do you think is the biggest flaw of this kind of warship?"

"It goes without saying, of course it is its power system." Qin Tao said.

power system?

The Germans are engaged in compound power and have designed complex gearboxes, but the British do not!In August last year, the British announced that their Type 45 destroyers will use a high-end comprehensive ship-wide power system, including electric propulsion.

I just bragged about this kind of motivation in the last episode of the show, is this episode going to belittle it?
"Of course there is no problem with the integrated power of the whole ship, but the British have a problem with the gas turbine. They use the WR-21 mid-stage cooling and reheating gas turbine. It sounds very powerful, but there is a huge problem. The heat dissipation system of this gas turbine has a problem. , it won’t break down in the Atlantic Ocean, but in the tropics, it will have to lie down.”

"Really? That's great, we'll focus on that in this episode."

How can you make your own 052B show off its power without belittling European warships?Zhang Zhong had already made preparations, but Qin Tao thought about it and shook his head: "Forget it, what if they change it after we talk about it? It's better to let them keep this kind of defect on the warship. "

Now, people will definitely ask, how do you know?This can't be explained. If it involves stealing information, maybe it can make Zhang Zhong feel ashamed. Besides, if it is said that the other party has changed it, then the Type 45 will be more mature.

Qin Tao didn't want this kind of thing to happen. The matter of cheating the British had to be carried out to the end.

Zhang Zhong nodded: "Then let's find something else? There is a ball on the head of the Type 45 destroyer, which is not pleasing to the eye."

"That's right, let's start with a ball on the head." Qin Tao agreed with this plan: "The sun is already setting in Britain, not the same as before. They are too poor to afford a four-sided phased array." The radar, which has to be rotated, is a joke in this day and age."

"Yes, they are poor, even if it is an aircraft carrier, they may not be able to build it." Zhang Zhong said.

This opened my mind again. When talking about British warships, I must talk about the British aircraft carrier. They are shouting every day to build a new Queen-class aircraft carrier, but they are building it. Why has there been no movement now?They must still have no money, they are all poor, so be poor if you are poor, stay honestly in your own one-acre three-point land, don't run around, wouldn't it cost more money to go for a trip?It's all taxpayer money!
After having dinner with Zhang Zhong, Qin Tao returned home. In the recent period, except for the occasional visit to Lao Maozi, he has been staying in the capital. Anyway, his wife and children are here, so he can enjoy more family happiness .

The modification plan of the arsenal ship can be directly handed over to the design institute for tinkering.

"Are you back?" When Qin Tao came back, Wu Shengli, who was sitting on the sofa and reading the newspaper, greeted him.

"Dad, don't you have a lot of things to do every day, why come back to read the newspaper when you have time?" Qin Tao was very curious.

"Wait for you."

"Wait for me? Just make a call and I'll be back. Why waste time like this? Your time is precious."

"Where is your preciousness, the content you discussed with Zhang Zhong must be very important. Our navy's project is not in a hurry. It is just an idea at present."

"Our navy's project? The navy wants to build new warships?" Qin Tao was surprised: "Could it be that he is greedy and determined to build a [-]-ton warship?"

During this period of time, news of the arsenal ship was spreading everywhere, and Qin Tao felt that the old man probably couldn't control it anymore, and wanted to tinker with this kind of destroyer.However, the navy's main expenditure is on that aircraft carrier. Do you still have the energy to fiddle with the [-]-ton large-scale drive?

"It's not a [-]-ton warship."

"Is that a [-]-ton comprehensive supply ship?" Qin Tao clearly remembered that he had proposed this idea some time ago.

"Not at all."

What is that?You should just say it directly.

"The navy has entered the Arctic waters, and we believe that in order to facilitate future operations, we need an advanced professional nuclear-powered icebreaker." Wu Shengli said.

Nuclear powered icebreaker?

Qin Tao opened his eyes wide: "The cost of this thing is not cheap!"

As long as something is mixed with nuclear power, the price will soar.

"Yes, the price is very high." Wu Shengli nodded: "So we need the help of your Mingzhou Group. Anyway, you will often take the Arctic route in the future. You may as well invest in the construction of a nuclear-powered icebreaker. When the Navy needs it in the future, Rent yours anytime."

No wonder I didn't call myself directly, it's embarrassing!

Mingzhou Group already has its own transportation company, both by sea, land and air. There are many cargo ships on the sea. As the weather warms up, many of these ships have begun to take the Arctic route. After all, the route is shorter, and there are Da Mao is a good friend.

If they travel frequently in the future, in order to save the cost of renting an icebreaker, they can consider building an icebreaker themselves, but this is not necessary. For a group, the first consideration is their own profit. The high cost of an icebreaker How many years will it take to pay back the investment?

Moreover, it is still nuclear powered!
"Nuclear power?"

"That's right, nuclear power. At present, the nuclear power system used by our nuclear submarines has matured, and the nuclear power system used by aircraft carriers is also making good progress. However, the Navy feels that if this kind of nuclear power system is directly used on the next aircraft carrier, it may be very difficult. There are some risks, so we think we should experiment first. Icebreakers should be the best choice."

At the beginning, the nuclear power system of the submarine was tested on land. It was the nuclear power plant of Mingzhou Group. After it operated stably on land, it was transplanted to the submarine.

What about the nuclear-powered aircraft carrier?Although there is already a floating nuclear power plant at sea, it is only floating on the sea. It is completely different from the test of icebreakers, which have to repeatedly hit the ice. In order to be more mature and safe, simply build a nuclear-powered icebreaker!
When the naval warships began to take the Arctic route, the navy felt that this need was more urgent, and they had no money, so they simply rubbed against the Mingzhou Group.

The biggest advantage of nuclear power is its unlimited endurance. It does not need to take up a lot of space to carry fuel. In the cold arctic regions, nuclear power can ensure that ships have a reliable power system. Therefore, for ordinary ships, nuclear power may It's just icing on the cake, and for icebreakers, nuclear power comes in handy.

The icebreakers of Lao Maozi and the Americans are almost all nuclear-powered. Now, the East is also building nuclear-powered icebreakers!Moreover, it can be used to verify the technology of nuclear reactors.

"The power of the nuclear power system on the aircraft carrier is not low, and the tonnage of our icebreaker is not small, right?" Qin Tao asked.

"Yes, if the Mingzhou Group's financial resources are strong enough, we hope that this is a [-]-ton icebreaker." Wu Shengli said: "In this way, the advantages of the nuclear power system can be fully utilized."

There are two nuclear reactors on the aircraft carrier, which are enough to propel the [-]-ton aircraft carrier to a speed of [-] knots. The icebreaker uses a nuclear reactor, and the displacement of [-] tons is just right, but everyone knows that the larger the displacement, the higher the cost of the ship .

Therefore, the specific size depends on how much Mingzhou Group intends to pay.

"Then what subsidies does the navy offer us?" Qin Tao asked.

This icebreaker belongs to the Mingzhou Group, but since the Navy has such a need, it will definitely be used frequently in the future, and even if there is a war, it can be leased directly.This has to be made clear. It is impossible for the Navy not to spend a penny. That would be too unfair to our Mingzhou Group.

"What do you want?" Wu Shengli asked.

"The entire nuclear power system, especially the nuclear fuel, has to be invested by the Navy, anyway, for the purpose of experimenting with nuclear reactors."

On a nuclear-powered ship, the most expensive thing is the nuclear reactor, Qin Tao is not at a disadvantage, we build the icebreaker, but the nuclear reactor navy will pay for it!
"Anyway, you don't have to worry about it. You have to build a marine reactor and put it on the icebreaker. We will help with the experiment. It will be good if there is no site fee. It will be free for you to experiment. It is impossible to let us buy the test subjects, right?"

"Okay, the navy can bear this part of the expenses." Wu Shengli said simply: "For the next aircraft carrier, we have to shed some more blood."

The first domestically-made aircraft carrier has not yet entered service, and the Navy is waiting for the second aircraft carrier!This is of course because the situation is changing too fast, the navy wants to expand as soon as possible, and has enough strength to protect the motherland.

"You Mingzhou Group has advanced dredgers. Can you use the principle of dredgers when manufacturing icebreakers?" Wu Shengli continued to ask.

Icebreakers mainly use two tricks. The icebreaker with a small displacement is to back up, and then rush to the ice surface to hit it, smashing the ice layer in front, but this method can only break through the ice surface with a small thickness.

Lao Maozi’s nuclear-powered icebreakers are all big monsters, so they used another method: directly rush the icebreaker onto the ice surface, then rely on the gravity of the hull to break through the ice surface, and continue to move forward, continuously crushing the ice layer. The effect is better, but it has high requirements on the ship, not only the displacement is large, the weight is heavy, but also the center of gravity must be stable, otherwise the ship may capsize.

Now, Wu Shengli has proposed a brand new method: can the ice surface be smashed directly with a reamer?

"Dad, since we want to innovate, we should have a bigger brain. Wouldn't it be easier for us to install a jet engine in the bow and melt the ice directly?"
