Warship of Great Power

After everything was settled, the next step was to drink.

"Qin, it's been a long time since we had a good drink." Looking at the gurgling wine, Nicholas had a complicated expression on his face.

"Yes, in the past few years, my movements have been greatly restricted. No matter where I go, I have to beware of being assassinated. Alas, I am not as free as I used to be. I think back then, with a few of my subordinates, I would dare to Run to Vladivostok.”

"Yeah, those days..." Nicholas also recalled the past.

Why are memories from the past always the best?

Because there are so many things to worry about now!

"Qin, the superiors have decided to hand over the maintenance task of the Type 949 nuclear submarine to you. However, we don't know when the funds will be collected." Nicholas said, "So, you don't have to be too anxious."

"Actually, it's not difficult to get the money together."

"Really? Tell me." Nicholas' eyes were full of expectation.

"Look for Ah San!"

"Tell me, how can you trick Ah San?" Nicholas' eyes were bright.

That night, the capital, Huanglou.

After seeing off Nicholas, Qin Tao came here. He looked at his father-in-law who was busy at work and did not disturb him. He sat on the sofa nearby and waited quietly.

"gone?"

"Well, let's go."

"Do you feel that now that you see Nicholas, you are a lot more unfamiliar than before?"

"Yes, Nikolai's status is getting higher and higher, his power is getting bigger and bigger, but he is getting more and more unfamiliar." Qin Tao said: "Human, that's it, the position is higher..."

At this point, Qin Tao glanced at his father-in-law and quickly changed the subject: "By the way, Dad, the Type 949 nuclear submarine that Lao Maozi is going to send over for modification still plans to go back to install the weapon system. If I guessed correctly, It should be a brand-new missile that replaces the Granite anti-ship missile. This missile is likely to be a hypersonic missile. Do we have similar weapons?”

Lao Maozi's Zircon missile is still very good. It can reach a speed of Mach 5 and still fly on a cruising trajectory. What about us? Are there similar products?

The YJ-12 and YJ-18 have been developed for several years. Have relevant units made further progress?

Wu Shengli glanced at Qin Tao: "You have been saying before that we should export advanced anti-ship missiles to earn foreign exchange, but we have never agreed. Are you waiting for more advanced anti-ship missiles to come out? Can you sell those advanced missiles openly?"

"Our Mingzhou Group does not produce anti-ship missiles. If we sell them, our brother units will make money. What does it have to do with us?" Qin Tao quickly denied.

"Tell me, what benefits can we get by modifying the Type 949 nuclear submarine for Lao Maozi?"

"Further control Lao Maozi's industry. Their shipbuilding industry has been completely abandoned. In the future, we will have to build all kinds of ships. Now even Lao Maozi can't even repair them, so we have to help. In this way, The relationship between Lao Maozi and our strategic partners is even deeper," Qin Tao said, "It is better to be friends with Lao Maozi than to be opponents."

Wu Shengli nodded: "Under the current situation, Lao Maozi should choose to be our friend. In the future... Lao Maozi's shipbuilding industry has been completely ruined. Their navy needs us, so they must continue to maintain good relations with us. Even if Nikolai goes down, it is impossible for anyone else to fall out with us. "

Nikolai will play a big role in the current friendship. What about replacement in the future? As long as their navy needs their own side, they will still maintain good relations.

"Now as long as we can help them repair the Oscar-class nuclear submarine, we will have to repair other nuclear submarines in the future. We can also fully master the technology of Lao Maozi nuclear submarines. For example, the nuclear submarines that Asan rented from Lao Maozi have a performance that we You will also know everything.”

Wu Shengli was stunned: "Ah San is renting a nuclear submarine from Lao Maozi again?"

Ah San has always wanted to have a powerful navy, but his domestic industry is not strong, so he can only increase his strength by purchasing or leasing. In terms of submarines, Ah San's navy can only rent Lao Maozi's nuclear submarines to meet his needs. own vanity.

At the very beginning, in the late 1980s, the Asan Navy leased a Type 670 nuclear submarine, named Chakra-1. At that time, Asan was very excited, finally becoming the sixth country in the world to own a nuclear submarine!

However, this submarine was too old after all, so when it expired after 1992, Ah San returned the nuclear submarine.

Later, Qin Tao and his father-in-law went to Lao Maozi's base together and threatened to rent a Type 971 nuclear submarine. Ah San was anxious and wanted to rent it. However, this kind of submarine was still a treasure in Lao Maozi's hands. So they didn't make the loan.

Now, the opportunity has finally arrived!

"Yes, if Ah San wants to realize the power of the navy, they must obtain nuclear submarines. Since they can't build them themselves, they can only rent them from Lao Maozi. Their dream of aircraft carriers continues to be shattered, so they can only use submarines. Come and satisfy your ego.”

"What advice did you give Lao Maozi?"

"That's right, otherwise I wouldn't have the money to repair the Type 949. If they don't have the money, we won't have access to it. Many of the technologies above are quite good, such as nuclear reactor technology."

The breakthrough in the technology of Dongfang's nuclear submarines can only be counted after the arrival of Kvasa and Krasnopolsky. As an excellent nuclear reactor expert, he directly let Dongfang use the advanced 150-megawatt nuclear reactor, which solved the problem of submarine power required underwater.

This kind of reactor is already backward in the old Russians. The old Russians' active nuclear submarines use 190-megawatt nuclear reactors. Although we already have a lot of advanced nuclear reactor technology, it is also possible to broaden our horizons to get in touch with the old Russians' nuclear reactors.

In addition to other submarine technologies, we can touch them all!

At this time, in the third design department of Mingzhou Group, the design drawings of the 949 nuclear submarine have been input into the computer, and the computer has begun to improve the repair plan.

"Now, pump-jet propulsion is already a trend. Our computer has designed an improvement plan for pump-jet propulsion. The use of this new propulsion system can increase the maximum underwater speed of the 949 nuclear submarine to 34 knots. At the same time, the quietness is reduced by more than 5 decibels." Kvasa introduced.

In the era of the development of the Type 949 nuclear submarine, it was good enough to have the processing technology of a seven-blade large side-slant propeller. How could there be such a thing as a pump-jet propulsion system? Even the current Russians don't have it. It was only used for the first time on the Type 955A nuclear submarine.

In the East, this technology is already very common.

"If it is other submarines, it is of course no problem to use this propulsion system, but it is not the case with the Type 949 nuclear submarine. Kvasa, you should know that this submarine has two propellers at the tail." Spasky sighed.

Generally speaking, the appearance of a submarine is an elongated teardrop shape, and the tail is the tip of the teardrop, with the rudder on top and the propeller extending from the back.

Most of the Russian submarines are like this. Under this scheme, if you want to replace the pump-jet, just replace the propeller directly.

However, the tail of the Type 949 nuclear submarine has two conical tails, each with a shaft pulled out from the tail, so two propellers appear behind the buttocks.

According to the Russians, this solution can improve system redundancy. If one of the propulsion systems fails, the other system can be used. In fact, the Type 671 nuclear submarine also has two sets, but the tail uses gears to connect the two transmission shafts, and then there is a propeller.

The Russians did not use this on the Type 949 nuclear submarine because the noise of the gears was too loud, so they were forced to use a layout of two transmission shafts and two propellers.

Of course, this is not enough to be against the sky. Among the Russian submarines, there is also a three-axis submarine, which is even more bizarre.

Now, it is not so easy to change the pump-jet.

"This is simple. In the power compartment, connect the turbine output shaft directly to the generator, so that all the power is converted into electrical energy, and then it can drive the pump-jet propeller at the tail. We modify the shape of the tail to make it streamlined."

"You mean, shaftless pump-jet?" Spasky was stunned.

The current mainstream pump-jet propulsion is just a shell on the outside of the propeller. This shell can reduce noise leakage and gather water flow, thereby reducing noise and improving propulsion efficiency.

It still needs to connect the transmission shaft from the inside of the submarine. As long as there is this transmission shaft, noise cannot be avoided.

The most advanced solution is to remove the transmission shaft and integrate the electric motor inside the pump-jet propulsion, so that an advanced shaftless pump-jet propulsion with minimal noise is made.

But... the technical difficulty is too great, at least there is no such technology in Russia.

Now, looking at the surprised Spassky, Kvasa is very calm: "Yes, shaftless pump-jet is the king, you don't have this technology?"

"We don't." Spassky answered very straightforwardly: "Don't you have it?"

Kvasa nodded: "Yes, of course we have it, so what modification plan do you plan to choose?"

"We want this shaftless pump-jet!" Spassky had almost no hesitation. They came here this time to learn advanced technology! Once this technology is mastered, it can be used in the improvement of domestic submarines.

"Okay, then we will design it in this way."

In the capital, Wu Shengli was still chatting with his son-in-law.

"So, you introduced all those advanced technologies to the Russians? Will they master these technologies?"

"They can't master them. If it is a shaft pump propeller, they may be able to master it, but they don't have the strength to do so. They can't produce the permanent magnets needed for the high-power motor on it." Qin Tao was very confident.

In fact, since the tail design has to be modified anyway, it is completely possible to simply connect the transmission shafts of the two nuclear reactors together through the reduction gear and then drive a water jet propulsion. There will definitely be noise, but it is not particularly serious.

However, Kvasa did not introduce it in this way. He skipped this technical route and directly introduced the most advanced technology, just not intending to let the Russians learn it.

Only the Golden Sun Motor Company in the world can make tens of megawatts of propulsion motors!

If you want the power density of the propulsion motor to be high enough, you need to use a permanent magnet motor, and you have to use a strong magnet on it. This kind of thing can only be produced by the East because it requires rare earth materials.

Over the years, Golden Sun Motor Company has developed a variety of permanent magnet motors, and has long had mature experience. Even if Lao Maozi took apart the motor, studied it, and then copied it, he would not be able to make one with the same efficiency, because this magnet They can't make it.

Therefore, only oneself has it!

"When they experience the benefits of this technology, they will abandon the use of shafted propulsion and directly use a shaftless propulsion system. Only we can produce this kind of thing. In other words, we will be able to control Lao Maozi's submarine production in the future. . Of course, this is just one aspect. We still have many technologies that we can show to Lao Maozi to make him feel inferior.”

Wu Shengli was speechless for a long time. His son-in-law was so awesome!

A week later, the Maoist capital, Moscow.

"After computer-aided design, we have completed the modification plan for the Type 949A nuclear submarine." Wang Guangrong, a technician from the Third Design Office of Mingzhou Group, stood in front of the projection screen and introduced it to a group of senior officials.

“First of all, the sonar part can be upgraded to a brand new sonar produced by our Dongfang, including bow sonar, side sonar and tail towed array sonar. Not only does the underwater search distance double, but the resolution is also greatly improved. Equipped with advanced digital processing systems, these sonar systems can clearly distinguish the specific location of the target and provide various basic data for torpedo launches.”

Lao Maozi's electronic technology is backward, so they still don't have side sonar arrays. Even their Type 885, which is the Yasen-class nuclear submarine, only has 6 side conformal sonar arrays. This number, It cannot be considered as a side sonar array at all.

The greater the number of units in this array, the larger the spacing, the sharper the main lobe, and the higher the resolution, the higher the beamforming and positioning performance obtained. At least 64 units are needed to become a real array.

At present, the domestic one uses a 64-unit array, while the export type has a 16-unit array. Even so, it is much better than Lao Maozi's own equipment.

Listening to these introductions, everyone present opened their eyes wide.

It’s not that they don’t know the benefits of having more units, and it’s not that they can’t add more units. It’s easy to plug in sonar receiving devices, but post-processing is too difficult!

As the number of units increases, the data that needs to be processed increases geometrically. Lao Maozi simply does not have this data processing capability, and only Dongfang has this ability!

"Can you describe the performance of this side sonar more vividly?" an official in a suit asked.

This meeting is not just for the Navy. The Navy has no objection to this improvement at all. The key is money!

"For example, it can hear the sound of the Los Angeles-class nuclear submarine two hundred nautical miles away, and it can accurately locate and guide our torpedo attack from 80 nautical miles away."

This distance is already impressive. The Yankees claim that their submarine’s sonar search distance is three to four hundred nautical miles, which is generally considered an exaggeration.

Everyone got excited.

"What if it's America's latest Seawolf class?"

"We don't have specific data on this, so we can't give an answer. However, even if the data is reduced by half, it should be enough for your use."

"Well, yes, these sonar should be replaced. However, if your Eastern sonar is replaced, how will we guide our torpedo attack? Are we required to open the weapon interface?"

This is a taboo for any weapons supplier. No one is willing to share their weapon secrets with others.

"If you just bind the shooting data, you can do it manually. If you need sonar to continuously guide you, then you will definitely need data interaction between the two." Wang Guangrong said.

Almost half of the torpedoes are wire guides. When going out, they drag a line directly and connect it to the mother ship. This way, they can get data support from the mother ship until they hit the target.

This kind of attack is very similar to semi-active radar-guided air-to-air missiles. However, with the development of the times, there are more and more torpedoes such as wake homing and acoustic homing. It depends on what Lao Maozi chooses.

"Actually, it's not a big deal. As long as you open the weapon interface, we can make an interface program so that all your weapon systems can be matched."

Not to mention simple weapon interface data, programs for different processors can be run through this compilation method. Looking at future generations, many mobile phone chips are used in computers, and there is no problem in running any X86 program, even in the latest The bottom layer is just compiled. To simply understand, it is just a docking program.

With the rapid development of electronic technology, this can also be done on weapon interfaces. Although it will affect the processing efficiency, the efficiency is not high in the first place, so it doesn't matter.

Sonar is the eyes of a submarine. For a submarine, the most important thing is how bright these eyes are. When everyone looks at these sonar data, they feel that they still cannot resist these temptations.

"By the way, I almost forgot. If it is a formation of surface ships sailing at high speed, our towed sonar array can complete precise positioning two hundred nautical miles away, accurate enough to guide anti-ship missile attacks."

The search distance has a great relationship with the noise of the target. Submarines use various methods to reduce their own noise, but surface ships do not pay much attention to it, especially aircraft carrier formations. Even if they want to reduce the noise, it is impossible. The noise during high-speed navigation is Quite strong.

"Change it, we must change it! Anyway, it's also a modified experimental boat, let's try it once!" The old Russians are not calm now.

What is the meaning of the 949A nuclear submarine? It is to attack the enemy's aircraft carrier!

In the past, this type of nuclear submarine was only responsible for launching missiles, and the search mission was undertaken by other systems. Now, with this advanced sonar, a single submarine can complete all the launch work!

Underwater, it is not easy to hear the aircraft carrier formation two hundred miles away! As for whether the missile launch will be discovered by the enemy's anti-submarine aircraft... As long as the anti-ship missiles carried are fired at the same time and all enemy warships are destroyed, won't you be safe?
