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."
"Yes, those days..." Nicholas also recalled the past.
Why are memories from the past always the best?
Because there are so many worries now!
"Qin, the superiors have decided to hand over the maintenance task of the Type 949 nuclear submarine to you, but we don't know when the funds will be collected." Nikolai said, "So, you don't have to worry too much."
"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 full of energy.
That night, the capital, Huanglou.
After seeing off Nicholas, Qin Tao came here and looked at his father-in-law who was busy at work without disturbing him. He just 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, and his power is getting stronger and stronger, but he is becoming more and more unfamiliar." Qin Tao said: "That's it, people, 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, with a speed of Mach 5 and a cruising trajectory. What about us? Do we have products of the same type?
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 Nicholas goes down and is replaced by someone else, he won't be able to fall out with us."
Nikolai will play a big role in the current friendship. What if there is a replacement in the future? As long as their navy needs their 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.
My own vanity.
At the beginning, in the late 1980s, the Asan Navy leased a Type 670 nuclear submarine, named Chakra-1. At that time, Asan was very excited, and finally became 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 rent it out.
Now, the opportunity has finally arrived!
"Yes, if Asan 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."
Dongfang's nuclear submarine technology breakthrough can only be counted after the arrival of Kvasa and Krasnopolski. As an excellent nuclear reactor expert, he directly let Dongfang use an advanced 150-megawatt nuclear reactor to solve the problem of submarines.
Problems with power needed underwater.
This kind of reactor is already considered backward in Lao Maozi. Lao Maozi's active nuclear submarine uses a 190-megawatt nuclear reactor. Although our country already has a large number of advanced nuclear reactor technologies, it is also difficult to come into contact with Lao Maozi's nuclear reactor.
It can broaden your horizons.
Coupled with other submarine technologies, our own side can touch them all!
At this time, at the Third Design Office of the Mingzhou Group, the design drawings of the Type 949 nuclear submarine had been input into the computer, and the computer began to improve the repair plan.
"Nowadays, pump-jet propellers have become a trend. Our computer has designed an improvement plan for pump-jet propellers. Using this new propulsion system, the maximum underwater speed of the Type 949 nuclear submarine can be increased to 34 knots. At the same time,
, in terms of quietness, it is reduced by more than 5 decibels." Kvasa introduced.
In the era of the development of the Type 949 nuclear submarine, it would have been good to have the processing technology of a seven-bladed large-bladed propeller. How could there be such a thing as a pump-jet propeller? Even today's old Maozi does not have it. Only in the Type 955A nuclear submarine
Just used it for the first time.
In the East, this technology is already very common.
"If it's other submarines, it's no problem to use this kind of propeller, but not the 949 nuclear submarine. Kvasa, you should know that this kind of submarine has two propellers at the tail." Spisky sighed.
Generally speaking, the shape of a submarine is an elongated water drop shape. The tail is the tip of the water drop, with the rudder surface placed on it and the propeller sticking out from the back.
Most of Lao Maozi's submarines are like this. Under this scheme, if you want to change the pump nozzle, you can just replace the propeller.
However, two conical tails were pulled out from the tail of the 949 nuclear submarine, and a shaft was pulled out from each tail, so two propellers appeared behind the butt.
According to Lao Maozi, 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 two are connected with gears at the tail.
The drive shaft is a propeller at the back.
Lao Maozi did not use this on the Type 949 nuclear submarine because the gear was too noisy, so he was forced to play with the layout of two drive shafts and two propellers.
Of course, this is not incredible enough. Among Lao Maozi's submarines, there is one that uses three axes, which is even more bizarre.
Now, it is not so easy to change the pump spray.
"This is simple. In the power cabin, the output shaft of the steam turbine is directly connected to the generator, so that all the power is turned into electrical energy, and then it can drive the pump jet propeller at the tail. We modify the shape of the tail and it becomes
streamline."
"You mean, shaftless pump?" Spassky was stunned.
The current mainstream pump-jet propeller is just a shell placed outside the propeller. This shell can reduce noise leakage and gather water flow, thereby reducing noise and improving propulsion efficiency.
It still needs to be connected to the drive shaft from inside the submarine. As long as there is this drive shaft, noise cannot be avoided.
The most advanced solution is to remove the drive shaft and integrate the motor into the pump propeller, thus creating an advanced shaftless pump with minimal noise.
But... the technical difficulty is too great. At least this technology is not available in China.
Now, looking at the surprised Spassky, Kvasa was very calm: "Yes, shaftless pumping is the way to go. Don't you guys not have this technology?"
"We don't." Spassky answered simply: "Don't you have?"
Kvasa nodded: "Yes, of course we have it. So, how do you plan to choose the modification plan?"
"We want this kind of shaftless pump!" Spessky said without any hesitation. They came here to learn advanced technology! Once they master this technology, they can use it to improve domestic submarines.
"Okay, then let's design it this way."
In the capital, Wu Shengli was still chatting with his son-in-law.
"So, you introduced all those advanced technologies to Lao Maozi? Will they master these technologies?"
"What they can't master, if it's a shaft pump, they might be able to master it, but they don't have the strength to do a shaftless pump. They can't produce the permanent magnets needed for the high-power motors above." Qin Tao is very confident.
.
In fact, the tail design needs to be modified anyway. It is completely possible to simply merge the transmission shafts of the two nuclear reactors together through reduction gears, and then drive a water jet propeller. The noise is definitely there, but it is not special.
serious.
However, Kvasa did not introduce it in this way. He went beyond this technical route and directly introduced the most advanced technology, just not intending to let the old man learn it.
Only Golden Sun Motors in the world can produce propulsion motors of tens of megawatts!
If you want the power density of the propulsion motor to be high enough, you need to use a permanent magnet motor, which requires strong magnets. This kind of thing can only be produced in the East because rare earth materials are needed in it.
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 motors, studied them, and then copied them, he would not be able to make one with the same efficiency, because this magnet
They can't make it.
Therefore, only our own side 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 you and make you feel inferior."
Wu Shengli was speechless for a long time. His son-in-law is 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 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.
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."
This chapter is not over yet, please click on the next page to continue reading! Lao Maozi’s electronic technology is backward, so they still don’t have a side sonar array. Even their Type 885, which is a Yasen-class nuclear submarine, only has 6
The number of side conformal sonar arrays cannot be considered as the level of side sonar arrays 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, or 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 sonar search distance is three to four hundred nautical miles, which is generally considered to be 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 sonar from Dongfang 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 directly drag a line 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, acoustic homing, etc. It all depends on what I choose.
"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 lot to do 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 must be changed! Anyway, it is an experimental boat modification, let's try it once!" Lao Maozi was not calm now.
What is the significance of the existence of the Type 949A nuclear submarine? It is to attack the enemy's aircraft carrier!
In the past, this kind of nuclear submarine was only responsible for launching missiles, and the search task was handled by other systems. Now, with this advanced sonar, a single submarine can complete all the launching work!
Underwater, hearing the aircraft carrier formation two hundred nautical miles away is already quite extraordinary! As for whether the missile launch will be discovered by the enemy's anti-submarine aircraft... Just fire out the anti-ship missiles you carry to destroy all the enemy warships.
