Chapter 558 039C Submarine

“The Navy is not satisfied with the performance of this 039 submarine.” In the office, Zheng Ming stood in front of the window, looking at the submarine in the dock over there, and said to Qin Tao.

"Although we are talking about a new generation of submarines, the design is not very bold, and there are still many design flaws." Qin Tao echoed: "Although I don't have specific data, I always feel that its seven-leaf side The design of the pitched propeller is problematic.”

In fact, even without Qin Tao's time travel, many domestic technologies are still developing. Specialized multi-axis CNC milling machines for processing submarines have also been developed. Otherwise, the 039 submarine launched in 1994 would not have It is impossible to use this propeller.

 However, it is the first time after all, so there are still many questions.

Although this is the first time for the Mingzhou Group, they have been able to hire a group of experienced submarine experts. These old guys were famous in the Red Empire era and have designed many types of submarines. All they need to do when coming to the East is to The equipment produced by Dongfang was blended in, and some design ideas provided by Qin Tao were used for reference.

 Just like the 039B currently exported, although it is only the first product of the Mingzhou Group, it can already compete with the famous 209 submarine, and many of its performances are better than the Kilo class.

“The Navy actually appreciates your Mingzhou Group’s products more. However, since your products have been exported, the Navy has some concerns.”

 Qin Tao realized what he was doing. Zheng Ming was giving him instructions!

Mingzhou Group is involved in too many industries, and Qin Tao is too busy. Submarine manufacturing has been making money, which is enough. There are also previous nuclear submarine bidding, and Qin Tao really doesn't take conventional submarines seriously.

 But now, Zheng Ming pointed it out.

 The navy is interested in it, but is still a little worried!

“The one we currently export is called 039B. If the navy needs it, we will continue to optimize this submarine and develop a 039C submarine.”

  039C? Hearing Qin Tao's words, Zheng Ming's eyes suddenly lit up: "Do you have anything more advanced than this kind of foreign trade submarine?"

 Qin Tao nodded.

 “Where is the specific advancement?” Zheng Ming couldn’t wait.

Although he will be here to supervise the construction of this sail training ship during this period, there are still many things that he is very concerned about. It would be great if the problem of the Navy's next-generation submarine can be solved here. .

"For a submarine, the most important thing is the silent performance. We must first continue to work on the silent performance. The biggest problem of the 039 below is the command tower, so we will start with the command tower. We want to Use a new kind of control tower.”

 A new control tower? Zheng Ming became interested: "Mr. Qin, what other tricks can you guys do with the command tower?"

The initial appearance of a submarine was similar to that of an ordinary warship, which was the linear shape of a surface ship. After all, it usually operated on the water, and would only dive down when it encountered an enemy. Later, as the threat from the water surface became greater and greater, , it was completely unsafe to be on the water surface, so I turned underwater. The shape of the submarine also changed into an elongated teardrop shape suitable for underwater navigation, and the bridge also evolved into a command tower.

This command tower is generally arranged at the front or middle of the submarine. It stands on the hull. The captain can command inside. It can also conveniently arrange periscopes and other devices, so it is also called the submarine command tower, and it is also like a multi-circuit command tower. Like a shell, it is also called a shell.

 In short, this device is essential for submarines, and even for convenience, the horizontal rudders of many submarines are also set on the conning tower.

However, the emergence of the control tower will still bring some troubles to the submarine, such as navigation resistance. Although this thing is small in area, the resistance it generates is equivalent to 20% of the submarine's navigation resistance. More importantly, Yes, if the design is not up to par, for example, the connection between the conning tower and the hull is not very smooth, it will produce significant navigation resistance and noise.

 In order to reduce resistance, many conning towers are designed to be relatively narrow. Similar to the Los Angeles-class submarines in the United States, the conning tower can only accommodate two people standing side by side, but the diameter of the submarine body is very large. Therefore, one drawback of this design is that a large horseshoe-shaped vortex will be generated on the side where the conning tower and the hull are connected, which will in turn produce greater navigation resistance and underwater noise.

It can be said that the design of the command tower is also very critical.

At this time, upon hearing Zheng Ming's question, Qin Tao smiled: "Let's ask our submarine designer to introduce this. Zhengyang, please invite Mr. Kvasa!"

Soon, Kvasa, who was helping at the dock, came back. After hearing Qin Tao's request, Kvasa immediately introduced excitedly: "After the successful trial of the first submarine 039B, we started the development of the next submarine. In terms of research and development, Mr. Qin gave us a lot of suggestions, especially the design of the mushroom-head submarine control tower. We have gone through a lot of research and proved that Mr. Qin’s idea is correct.”

“Mushroom head?” Zheng Ming was a little surprised: “What is mushroom head?”

"The shape of this command tower is narrow at the bottom and wide at the top, just like a mushroom." Kvasa said: "Moreover, it is not circular, but a polygonal fold line design. This design is more consistent with Fluid mechanics, reducing navigation noise and reducing navigation resistance.”

The bottom is narrow and the top is wide. This design is actually more in line with fluid mechanics? Did you hear it correctly? Zheng Ming was a little surprised.

Qin Tao had a smile on his face. This is the benefit brought by advanced design concepts. Others would never expect it. They would only focus on lowering the height of the command tower and try to design it into a streamlined shape. However, their own side did the opposite. Put a big hat on the command tower!

This is like a bulge in the air intake of a fighter jet. No one knew about it before it was invented. This kind of mushroom head shape with a hat on the command tower only began to appear in the 21st century. Now these Of course people don’t know.

This mushroom head has many benefits. It can effectively avoid those horseshoe-shaped vortices, because this hat can hook the water flow and reduce the flow of water around the control tower, thus reducing navigation resistance. Of course, there are many other benefits. For example, on the water surface, this mushroom head can better reduce radar reflection waves and prevent others from being discovered.

 The mushroom head is larger, has more internal space, and can hold more things.

At this time, Kvasa said as he roughly drew a rough sketch of the shape of the mushroom head on the drawing. Zheng Ming looked at the design of the command tower and couldn't help but sigh in his heart. Sure enough, in terms of innovation, Ming Ming Zhou Group is definitely at the forefront. Other domestic design bureaus often refer to foreign designs, but what about here? It has become a reference for foreign countries!

“Don’t Lao Maozi have a streamlined control tower design? We don’t seem to be following Lao Maozi’s technical route?” Thinking of something, Zheng Ming continued to ask.

When it comes to designing nuclear submarines, Lao Maozi definitely has the most experience. The nuclear submarines that were in service in the 1980s were even more beautiful in design. Lao Maozi’s control tower and submarine are integrated very well, just like fish in the deep sea. The same as those directly evolved from the class.

"That design is indeed very beautiful, but it also has many disadvantages." Kvasa introduced: "That streamlined control tower is quite difficult to process. Whether it is welding steel plates or laying silencer tiles, there are many problems. Moreover, although it looks low and beautiful, the navigation stability of this kind of control tower is far from enough. Therefore, although it is low, it is long front and rear. This kind of low and elongated control tower is in the water. When sailing at high speed, the resistance is not small. Of course, the noise is indeed greatly reduced."

That kind of design has advantages and disadvantages, but now this mushroom head design has low noise and low resistance, all of which are taken care of!

“Kvasa, let’s introduce the advanced technology of our submarine to Lao Zheng.” Qin Tao said.

 Kvasa continued to draw along the control tower just now: "Another feature of our 039C is that it will use an X-shaped tail rudder."

When a submarine sails underwater, it mainly relies on its tail rudder to change its attitude. Generally, the tail rudder is cross-shaped. In this way, if you want to turn left and right, you need to move the vertical rudder surface. If you want to move it up and down, you have to move it. Operating the horizontal rudder surface is relatively intuitive.

However, this kind of rudder surface has many flaws. For example, the wake generated by the submarine's control tower during navigation will have a certain impact on the vertical rudder surface. Once fighting in shallow water, the vertical rudder surface will It might hit the bottom of the sea.

  The X-shaped rudder completely avoids such problems and can be said to be a trend in submarine design.

It avoids the control tower and does not have to worry about hitting the bottom of the sea. However, the operation of this kind of rudder is inconvenient. If you want to turn, which rudder should be moved?

 It is no longer possible to accurately adjust the steering surface manually. This kind of steering surface needs to be calculated by a computer. Whether it is in the horizontal or vertical direction, four steering surfaces need to be moved together and operated together to achieve the driver's purpose.

However, it is also because of this that the operation efficiency of this kind of rudder surface is very high. No matter what time, the four rudder surfaces can participate in the operation together.

 Mingzhou Group’s Third Design Office has been studying submarine technology. They have already conducted a large number of computer simulations and actual model tests to overcome this project.

"Since we are talking about the tail, let's continue by saying that we are already using the pump push method on the existing 039B submarine. This method further improves the silentness of the submarine, but it is still not the best." Kvasa continued: "According to the R&D plan of the relevant departments, when this submarine officially starts production in the future, it is likely that our shaftless pump technology will be mature. By then, we can replace it with this more advanced The advanced propulsion system further reduces the noise of our submarines."

 The submarines in the East have begun to use pump propulsion, which is already on the same starting line as the West. However, they are not satisfied yet, they can do better!

Pumping has improved efficiency and reduced noise. However, current pumping still needs to be driven by the transmission shaft output from the motor at the tail of the submarine. This transmission shaft is still the source of noise. In shaftless pumping, the propeller blades are directly installed on the On the annular duct, the traditional drive shaft is completely eliminated, which makes it even quieter.

At this time, Zheng Ming could only marvel.

I originally thought that 039B was already the most advanced, and Mingzhou Group couldn’t come up with any tricks. The most it could do was make modifications. Who would have thought that Mingzhou Group could actually carry out so many innovations!

 After these improvements, the performance of the submarine can be greatly improved!

 So, what else does the Navy have to say? As long as the funds are in place, you must come directly to Mingzhou Group to start construction. It has the most advanced technology here!

“Is there anything else?” Zheng Ming continued to ask.

"For other things, we are looking forward to the cooperation of our brother units, such as the AIP system. I hope that their new generation of high-horsepower Stirling engine can be successfully developed, so that our underwater endurance time can be further increased, and there is also the development of sonar. If the unit can provide a new generation of sonar, including side sonar, the submarine's underwater observation capabilities can be further improved." Qin Tao took over the conversation: "There is also the submarine's automation system. The more advanced this system is, the better the submarine's underwater observation capabilities will be. The fewer passengers will be needed inside.”

 These are not things that Mingzhou Group can solve. After all, they are just a shipbuilder and a general assembly plant. All parts are from brother units.

Zheng Ming nodded: "Well, these are all looking forward to breakthroughs by relevant units. However, the overall design of your Mingzhou Group is also very good. By the way, what is the section behind your submarine control tower?"

Kvasa has almost finished the sketch, which is very beautiful. Behind the control tower, Kvasa is drawing vertical pipes one by one. He doesn’t know what they are for.

"This, of course, is the vertical launch mechanism." Kvasa glanced there: "Launching only from the torpedo tube is too backward. Advanced submarines must have a vertical launch compartment, whether it is a conventional diesel-electric submarine or a Nuclear submarines all need such a cabin.”

Vertical launch module section!

When they were bidding for nuclear submarines, the project proposed by the Mingzhou Group included such a cabin. However, the technology was too advanced, so it was temporarily abandoned. But now, this advanced conventional submarine has this kind of cabin again. cabin section.

In the past, the main combat weapon of submarines was torpedoes. However, with the continuous advancement of technology, this weapon has become outdated. After all, torpedoes are slow and have short range, which is incomparable with missiles. After the submarine hides its whereabouts, it not only It can only launch sneak attacks on enemy warships, but it can also directly launch missiles to attack enemy land targets.

 Hence, vertically launching anti-ship or cruise missiles is a capability that the next generation of submarines must acquire!

Zheng Ming nodded: "Your submarine design is refreshing. I will take the time to write a report on this and report it to my superiors."

Zheng Ming looked at the dock outside again, looking at the 039 submarine where the silencer tiles were being laid. He sighed in his heart. It is estimated that the military ship will not have the opportunity to build another submarine in the future, right? After all, their submarines are too backward!

“Ding-a-ling!” At this moment, the phone on the table rang.

"Hello."

“Mr. Qin, we have completed the phased tasks, and the combat command system on the 001 aircraft carrier has been installed and debugged!”

Upon hearing the news, Qin Tao was immediately filled with excitement: "Okay, I'll go over and take a look!"

The style of the aircraft carrier outfitted is still the same, and many people are still busy here. The scaffolding on the island is still there, and through the gaps in the scaffolding, you can easily see the phased array radar embedded on it!

The white casing of the radar has been installed, forming a sharp contrast with the color of the surrounding ships and islands, making it easy to see at a glance.

 The completion of the four-sided phased array means that the aircraft carrier outfitting work has entered a new era!

"Mr. Qin, you are here." Makarov shouted from a distance: "This phased array radar is much better than our previous Sky Sentinel!"

The Sky Sentinel belongs to the last glory of the Red Empire. It is equipped on Kirov-class cruisers and several heavy-duty aircraft-carrying cruisers. It becomes the last swan song of the empire. In terms of data, it is still quite advanced. For example, the frequency is almost from The VHF band spans all the way to the S-band, and it can do anything from long-range search to missile guidance.

 In fact, the reliability of this kind of radar is very low, the degree of automation is very poor, and it has hardly played any role.

 The Dongfang's set is different. This is the world's first set of carrier-based active phased array radars. Moreover, the degree of automation is quite high. The core of the entire aircraft carrier command is almost based on this system!

At this time, Makarov had long forgotten his days in the Black Sea Shipyard. For him, this was already a brand new world, and he had long been separated from the past.

“Of course, modern warfare must be information-based and automated. Without advanced active phased array radar, there is no way to go out to meet people, go up and have a look!”

After passing through the scaffolding passage and entering the interior of the ship island, Qin Tao went directly to the bridge. Inside, various cabinets were fully placed, and each operating table was equipped with a monitor and a keyboard. The mouse is full of modern feeling at first glance.

"This is a modern command system. It can not only command the normal operation of the aircraft carrier's aircraft and the operation of the aircraft carrier, but also command the entire formation." Babbage was also very emotional on the side: "The degree of automation of this system is very high. High, it uses the current Loongson computer as the brain, optical fiber transmission as the nerve, and connects the command desk, database and various standard display consoles through dual redundant switched Ethernet and video buses. It has reached the world's advanced level!"

 In recent years, the progress in the East has been so rapid! In the beginning, the computers in the combat command systems used by warships had to be purchased from outside sources, but now they can be produced by ourselves!

This kind of speed is simply unbelievable.

"This is just the beginning. What we produce next will be more advanced." Qin Tao said to everyone: "This ship is just a ski jump. When our electromagnetic catapult matures, the next ship may be ejected. , that is the real aircraft carrier comparable to the West."

"Mr. Qin, someone wants to see you." Just when Qin Tao and the people around him were looking forward to a bright future, Xu Zhengyang came over and said to him.

"who?"

 “The person in charge of Sanhang Heavy Industry Shipyard, Zheng Zhenze.” Xu Zhengyang said.

“What are they here for?” Qin Tao was a little curious.

Xu Zhengyang looked at Qin Tao with a meaningful look: "Mr. Qin, do you really not know?"

Qin Tao seemed to understand something: "Yinwa Steel?"

Xu Zhengyang nodded.

 “Let him wait in the reception room and see him again in an hour or two.”

Since the person is here to make a purchase, of course there is no need to be polite. Let the person sit on the bench for two hours first.

"oh."

In the reception room of Mingzhou Group, Zheng Zhenze was restless.

 Sanhang Heavy Industry is also a well-known shipbuilding organization in the world. Unlike Dazhou Heavy Industry, their Sanhang Group has a wide range of interests. Shipbuilding is one aspect, and electronics is the main business. However, now their shipbuilding industry is about to encounter a crisis, which makes them very anxious.

Zheng Zhenze really had no choice but to come to Mr. Qin for help, hoping to help him.

 Waiting, waiting, the hands of the clock on the wall kept moving. Just when Zheng Zhenze's patience had been exhausted to the extreme, a voice finally came from outside.

"Mr. Zheng, I'm very sorry. There are too many things in the group, so I just took some time." Qin Tao walked in with a smile and held his hand enthusiastically: "Mr. Zheng, I kept you waiting for a long time!"

Zheng Zhenze breathed a sigh of relief and quickly made polite remarks. After the two parties sat down, Zheng Zhenze said: "Mr. Qin, we know that you are very busy, so we won't say anything else. I am here this time to express my gratitude to you." Could you please tell me when the Yinwa Steel we ordered will be delivered? We are still waiting in China!"

"Yinwa Steel?" Qin Tao was stunned: "You haven't received the goods yet? Zhengyang, what's going on?"

"Mr. Qin, we currently have a lot of orders, and the production line has been producing non-stop. The Chongming Island Shipyard, which we cooperate with Sanhang Heavy Industry, is also currently producing natural gas ships. Therefore, the demand for Yinwa Steel is huge. It’s very big. The production capacity of Mingzhou Steel Plant is limited. We can only give priority to our own use at present. As for providing it to our brother units, we can only put it behind.”

The global demand for natural gas ships is growing, and of course the gap in the important shipbuilding material Yinwa Steel is also growing. In addition to Mingzhou Group, there are other domestic brother shipyards that are also building natural gas ships, and they all have to When Yinwa steel is used, it will be exported only after these are satisfied.

"But, Mr. Qin, you have to provide it to us according to the order. We have been waiting for a year and have not received a piece of Yinwa steel. We paid the full price at the beginning! We are still partners, how can you treat us like this? Us?" Zheng Zhenze was worried.

"Yes, we are the most important partners!" Qin Tao said: "Let's do this, I will ask Mingzhou Steel Plant to find ways to expand production capacity! When production capacity comes up, I will give it to you first. By the way, You can also look for diversified channels, France also has Invar Steel!"
