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 questionable."

In fact, even without Qin Tao's crossing, many domestic technologies are still developing, and the special multi-axis CNC milling machine for processing submarines has also been developed. Otherwise, the 039 submarine that was launched in 1994 would not It is impossible to use such a propeller.

  However, since this is the first time, there are still many problems.

Although it is the first time for Mingzhou Group, they can hire a group of experienced submarine experts. These old men are famous in the era of the Red Empire. They have designed many types of submarines. What they need to do when they come to the East is to use The equipment produced by Dongfang was mixed in, and some design ideas provided by Qin Tao were referred to.

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

   "The navy actually appreciates your Mingzhou Group's products more, but since your products have been exported, the navy has some concerns."

   Qin Tao came to his senses, Zheng Ming was pointing him out!

  Mingzhou Group is involved in too many industries, and Qin Tao is too busy. Submarine manufacturing has been making money.

  But now, Zheng Ming pointed it out.

  The navy is interested, but still a little worried!

   "Currently, what we export is called 039B. If the navy needs it, we will continue to optimize this submarine and build a 039C submarine."

  039C? Hearing Qin Tao's words, Zheng Ming's eyes lit up: "Do you have any more advanced foreign trade submarines?"

  Qin Tao nodded.

   "Where is the specific advancement?" Zheng Ming couldn't wait.

Although he is going to supervise the construction of this sail training ship during this period of time, 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 is solved here. up.

"For a submarine, the most important thing is the quietness performance. We still need to continue to work on the quietness performance. The biggest problem with the 039 below is the conning tower, so let's start with the conning tower. Use a new kind of conning tower."

  New command tower? Zheng Ming became interested: "Boss Qin, what tricks can you guys do with the command tower?"

The initial appearance of the submarine was similar to that of an ordinary warship, which was the line shape of a surface ship. After all, it usually moved on the water surface, and would only go down when it encountered an enemy. Later, as the threat from the water surface became greater and greater , It was completely unsafe on the surface of the water, so it went underwater. The shape of the submarine has also become an elongated drop shape suitable for underwater navigation, and the bridge has also evolved into a command tower.

This conning tower is generally arranged at the front or middle of the submarine. It stands upright on the hull, and the captain drills inside to command. At the same time, it is also convenient to arrange periscope and other devices, so it is also called the submarine commanding platform, and it is like a multi-circle Like a shell, also called enclosure.

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

However, the appearance of the conning tower will still bring some troubles to the submarine, such as sailing resistance. Regardless of the small area of ​​this thing, the resistance generated is equivalent to 20% of the submarine's sailing resistance. Yes, if the design is not good enough, for example, if the connection between the conning tower and the hull is not very smooth, there will be obvious sailing resistance and sailing 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 there side by side, but the diameter of the submarine hull is very large. Therefore, one of the disadvantages of this design is that a large horseshoe-shaped vortex will be generated on the side of the connection between the conning tower and the hull, which in turn will generate greater navigation resistance and underwater noise.

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

   At this time, Qin Tao smiled when he heard Zheng Ming's question: "Let's invite our submarine designer to introduce this, Zhengyang, and invite Mr. Kwasha!"

Soon, Kwasha, who was helping at the dock, came back. Hearing Qin Tao’s request, Kwasha immediately introduced excitedly: “After the successful sea trial of the first 039B boat, we started the development of the next submarine. In research and development, Mr. Qin gave us many suggestions, especially the design of the mushroom head submarine conning 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 a mushroom head?"

"The shape of this command tower is narrow at the bottom and wide at the top, just like a mushroom." Kwasha said: "Moreover, it is not circular, but a polygonal broken line design, which is more in line with Hydrodynamics, reduce sailing noise, reduce sailing resistance."

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

Qin Tao has a smile on his face. This is the benefit brought by the advanced design concept. Others will never think of it. They will only focus on reducing the height of the conning tower and try to design it as streamlined as possible, but their own side does the opposite. Put a big hat on the conning tower!

This is like a bulge for the air intake of a fighter jet. Before it was invented, no one knew about it. This kind of conning tower with a cap on it, shaped like a mushroom head, only began to appear in the 21st century. Now these Of course people don't know.

  The benefits of this mushroom head are too many, it can effectively avoid those horseshoe-shaped vortices, because this cap can hook the water flow and reduce the flow of water flow around the conning tower, thus reducing the sailing resistance. Of course, there are many other benefits. For example, on the water surface, this mushroom head can better reduce radar reflections and prevent others from being discovered.

  The mushroom head is larger, the interior space is larger, and more things can be loaded.

At this time, Kwasha said while drawing a rough sketch of the shape of the mushroom head on the blueprint. Zheng Ming looked at the design of the command tower, and couldn't help but sigh in his heart. Sure enough, if we want to talk about innovation, Ming Zhouzhou Group is definitely at the forefront. Other domestic design bureaus often refer to foreign designs, but what about here? Has become the object of foreign reference ah!

   "Don't Lao Maozi have a streamlined command tower design? We don't seem to follow Lao Maozi's technical route?" Zheng Ming continued to ask what came to his mind.

In terms of designing nuclear submarines, Lao Maozi definitely has the most experience. Those nuclear submarines that served in the 1980s were even more beautifully designed. Lao Maozi's conning tower and submarines are very well integrated, just like fish in the deep sea The same as the direct evolution of the species.

"That design is indeed very beautiful, but there are also many disadvantages." Kwasha introduced: "The streamlined conning tower is quite difficult to process. 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 in front and back. When sailing at high speed, the resistance is not small. Of course, the noise is indeed greatly reduced."

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

   "Kwasha, let me introduce the advanced technology of our submarine to Lao Zheng." Qin Tao said.

  Kwasha continued to draw along the command tower just now: "Our 039C, another feature is that it will use the X-type tail rudder."

When a submarine sails underwater, it mainly relies on the tail rudder to change its attitude. The general 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 up and down, you have to It is more intuitive to operate the rudder surface in the horizontal direction.

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

  X-type rudder completely avoids such problems, which can be said to be a trend in submarine design.

  It avoids the conning tower, and there is no need to worry about poking the bottom of the sea. However, the operation of this kind of rudder surface is inconvenient. If you want to turn, which rudder surface should you move?

  It is no longer possible to accurately adjust manually. This kind of rudder surface needs to be calculated by the computer. Whether it is horizontal or vertical, all four rudder surfaces need to be moved 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 at any time, the four rudder surfaces can participate in the operation together.

  The third design office of Mingzhou Group has been researching submarine technology. They have already carried out a large number of computer simulations and actual model tests, and they have overcome this project.

"Now that we have talked about the tail, let's go on to say that we are already using the pump push method on the existing 039B submarine. This method further improves the quietness of the submarine, but it is still not the best." Kwasha continued: "According to the research and development plan of relevant departments, when this submarine officially starts production in the future, it is very likely that our shaftless pump thrust technology will be mature. At that time, we can replace it with this more advanced submarine." Advanced propulsion systems to further reduce the noise of our submarines."

  Eastern submarines have started to use pumps, which is already on the same starting line as the West, but they are not satisfied yet, they can do better!

The pump boost improves the efficiency and reduces the noise. However, the current pump still needs to be driven by the drive shaft output by the electric motor at the tail of the submarine. This drive shaft is still the source of noise. The shaftless pump pushes the propeller blades directly. On the ring duct, the traditional drive shaft is completely eliminated, and its quietness is even better.

  At this moment, Zheng Ming was only amazed.

   Originally thought that 039B was already the most advanced, and Mingzhou Group couldn’t change anything. At most, it would just modify it. Who would have thought that Mingzhou Group could still 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. This place has the most advanced technology!

   "Is there anything else?" Zheng Ming continued to ask.

"Others, we look forward to the cooperation of our brothers. For example, the AIP system, I hope their new generation of high-horsepower Stirling engine can be successfully developed, so that our underwater battery life can be further increased, and there are related research and development of sonar. Unit, if it can provide a new generation of sonar, including sideboard sonar, the underwater observation capability of the submarine can be further improved." Qin Tao took over the conversation: "There is also the automation system of the submarine. The more advanced this system is, the better the submarine will be. There will be fewer occupants needed inside."

   These are not things Mingzhou Group can solve. After all, they are only shipbuilders, just an assembly plant, and all kinds of parts are from brother units.

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

  Kwasha has almost drawn up the sketch, which is very beautiful. Behind the command tower, Kwasha is drawing vertical pipes one by one. I don’t know what they are for.

"This, of course, is a vertical launch mechanism." Kwasha glanced there: "It is too backward to launch only from torpedo tubes. Advanced submarines must have a vertical launch section, whether it is a conventional diesel-electric submarine or All nuclear submarines need such a cabin.”

  Launch the pod vertically!

When bidding for nuclear submarines, the project proposed by Mingzhou Group had such a cabin section, but the technology was too advanced, so it was temporarily abandoned, but now, this advanced conventional submarine appeared again. compartment.

In the past, the main combat weapon of submarines was torpedoes, but with the continuous advancement of technology, this weapon has become outdated. After all, torpedoes are slow and have a short range, which is incomparable with missiles. It can only launch a sneak attack on the enemy's warships, and it can directly launch missiles to attack the enemy's land targets.

   Therefore, launching anti-ship or cruise missiles vertically 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 this into a report and report it to my superiors."

  Zheng Ming looked out at the dock again, and saw the 039 submarine where the sound-absorbing tiles were being laid there, and he was filled with emotion. Wu Chuan probably won’t have the opportunity to rebuild submarines in the future, right? After all, their submarines are too backward!

   "Dingling!" At this moment, the phone on the table rang.

"Hello."

   "President Qin, we have completed the staged tasks, and the combat command system on the 001 aircraft carrier has completed the installation and commissioning!"

  Hearing the news, Qin Tao's face was filled with excitement: "Okay, I'll go and have a look!"

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

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

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

   "President Qin, you are here." From a distance, Makarov shouted: "This phased array radar is much better than our previous sky sentry!"

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. The VHF band spans all the way to the S band, and it can do everything from long-range search to missile guidance.

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

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

   At this moment, Makarov has long forgotten the days in the Black Sea Shipyard. For him, this place is already a brand new world, and he has long been separated from the past.

   "Of course, modern warfare must be informationized and automated. Without advanced active phased array radar, it is impossible to go out to meet people. Go up and have a look!"

Passing through the passageway of the scaffolding and entering the interior of the ship island, Qin Tao went directly to the position of the bridge. Inside, all kinds of cabinets are also fully placed, and each console is equipped with a monitor and a keyboard. The mouse is full of modern feeling at first sight.

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

  In the past few years, the progress of the East has been too fast! The computers in the combat command system used by warships at the beginning had to be purchased from outsiders, but now they can be produced by themselves!

   This speed is unbelievable.

"This is just the beginning, and our own production will be more advanced." Qin Tao said to everyone: "This ship is just a ski jump take-off. When our electromagnetic catapult matures, the next one may be a catapult take-off. , that is the real aircraft carrier comparable to the West."

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

"who?"

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

   "What are they doing here?" Qin Tao was curious.

  Xu Zhengyang looked at Qin Tao with meaningful eyes: "Mr. Qin, you really don't know?"

  Qin Tao seemed to understand something: "Inwagang?"

  Xu Zhengyang nodded.

   "Let him wait in the reception room and see him in an hour or two."

  Since you came here to buy, of course you don't have to be polite, let the other party sit on the bench for two hours first.

"oh."

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

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

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

  Wait, wait, the hands of the clock on the wall kept moving. Just when Zheng Zhenze's patience was exhausted, a voice finally came from outside.

   "Mr. Zheng, I'm very sorry, there are too many things in the group, I just took time out." Qin Tao walked in with a smile, and enthusiastically shook his hand: "Mr. Zheng, I kept you waiting!"

Only then did Zheng Zhenze heave a sigh of relief, and hurriedly made some polite remarks. After the two parties sat down, Zheng Zhenze said: "Mr. Qin, we know you are very busy, so we won't say anything else. Please urge me, when will the invar steel we ordered be delivered, we are still waiting in the country!"

   "Inwagang?" Qin Tao was taken aback: "You haven't received the goods yet? Zhengyang, what's going on?"

"Mr. Qin, we have a lot of orders at present, and the production line has been producing non-stop, and the Chongming Island Shipyard, which we cooperate with Sanhang Heavy Industry, is also producing natural gas ships at present, so the demand for Inwa steel is very large. Very big, the production capacity of Mingzhou Iron and Steel Plant is limited, we can only give priority to satisfying our own use at present, and as for providing it to brothers, we can only put it in the back.”

The global demand for natural gas ships is increasing, and the shortage of important shipbuilding materials Invar steel is of course also increasing. In addition to Mingzhou Group, there are other brother shipyards in China that are also building natural gas ships. When Invar steel is used, it will not be exported until all these are satisfied.

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

"Yes, we are the most important partner!" Qin Tao said: "Well, I will ask Mingzhou Iron and Steel Works to try its best to expand production capacity! When the production capacity comes up, it will definitely be provided to you first. By the way, You can also seek diversified channels, there is also Invar Steel in France!"
