A sneeze!
Qin Tao sneezed.
“Brother Tao, what’s wrong?” Zhao Ling looked at him with concern.
"It's okay, I guess some guy is scolding me behind my back." Qin Tao raised his head and looked at the sandstorm blowing under the biting north wind. Although Huanglou was close at hand, he couldn't see clearly.
Afforestation, wind protection and sand fixation are very important tasks. However, when the sandstorms are gone and haze starts to come again, nature likes to play tricks on people.
However, protecting the environment is important, and developing the economy is even more important. The West shouts about environmental protection every day, but it is just because they have developed their economy. When they developed, the damage to the environment was more serious. Now they shout the slogan of protecting the environment to curb some development. Just China.
Who is scolding me behind my back? Those who are dissatisfied with the rise of Mingzhou Group? Or those customers? Like the colonel? They came to place an order for warships, and they pushed it to five years later. But when Da Mao came to place an order, he immediately got on the slipway. Will this guy come to him to protest?
Since the contract has been signed, there is no point in protesting again.
“The weather here is really weird.” Kvasa, who was following him, complained, then tightly held the document bag in his hand.
Qin Tao continued to walk forward, and finally braved the wind and sand, and arrived at the Huanglou with a few people. Entering the conference room, it was already full of people.
"Sorry, we're late." Qin Tao patted the dust off his body as he entered. There was sand in his hair. Sure enough, people in a certain area like to wrap their heads in white cloth. That makes sense. In a climate like this, The white cloth can reduce a lot of troubles. My hair is short, so it's fine. Zhao Ling's hair is long, so she will definitely have to take a shower after going back.
"It doesn't matter, the time has just reached eight o'clock, which is not too late. Since you are here, come up and report quickly." Wu Shengli said. Next to Wu Shengli, there were some people sitting, and they all came to observe the ship. 096 design plan, after all, this meeting is of great importance. The design plan of the 096 nuclear submarine will be completely decided, and then construction will begin!
“Okay, let’s ask our chief engineer, Mr. Kvasa, to introduce our plan to you first. After the introduction is completed, we can answer your questions.”
Kvasa carried his document bag and walked up quickly. He had been waiting for this day for a long time.
When he was in Damao, Kvasa thought that he would be insulated from nuclear submarines in this life and would never have the opportunity to design any nuclear submarine. Unexpectedly, when he came to the East, Kvasa started a new life. He tinkered with 095, and now he has Start building 096. This nuclear submarine will become the world's most advanced ballistic missile nuclear submarine and become an underwater monster!
"Hello everyone, everyone should be aware of the basic parameters of our 096 nuclear submarine. This is a nuclear submarine with a length of 170 meters, a pressure hull diameter of 13.5 meters, and an underwater displacement of 17,000 tons. It carries 24 JL-3 missiles. Missiles, now, let me give you a detailed introduction."
Kvasa took out his notebook and put it on the projection screen. After the screen jumped several times, the outline of a large nuclear submarine appeared.
Everyone present held their breath.
"Because the ballistic missiles it carries are too big, we can't completely cancel the turtle's back. However, in the past few years, we have made a lot of models and conducted a lot of simulations to find the best appearance design. The first thing everyone pays attention to is It should be this turtle’s back, let’s start from here.”
The diameter of the pressure shell is 13.5 meters, and the length of the ballistic missile launch tube is 14 meters. Therefore, the turtle's back is inevitable. The next step is to see how to minimize the impact of this turtle's back.
As you can see from the projection screen, the integration of the turtle's back and the hull is very good.
The turtle's back is placed behind the conning tower, so the conning tower of this kind of nuclear submarine is very forward. There is a horizontal shell rudder above the front of the conning tower. From the bottom of the rudder surface, where it is connected to the hull, a directional rudder appears. The **** at the rear is streamlined, perfectly integrated with the command tower, and continues to rise backwards. When it reaches the rear of the command tower, it has reached the height to accommodate missiles.
The back of the conning tower also has a slope, which is further integrated with the position of the missile launcher. This design makes the construction of the conning tower more difficult, and there are also many problems in laying silencer tiles, but it makes the entire submarine more perfect and more smoother and more beautiful.
The back is flat until all 24 missile launchers are installed, and then a lowering **** appears at the back, which is perfectly integrated with the hull of the boat.
Even though there is a turtle's back, the impact of the turtle's back has been minimized.
"After this design, the turtle's back will bring almost no additional navigation noise, and the resistance will be greatly reduced. Of course, we also hope that relevant units can further reduce the diameter of the missile. When the next generation comes, our hull will be able to Accommodate the missiles.”
Kvasa feels that he can work for another twenty years to reach the next generation of nuclear submarines. At this time, he is full of energy.
“As for the submarine structure, we still adopt the most suitable single-double-hull hybrid structure.”
Needless to say, for these ballistic missiles, it is necessary to make holes in the pressure shell and install the launch tube. At the same time, the launch tube is longer than the pressure shell. The outside must still be wrapped with a non-pressure shell, so that it can The appearance forms a perfect streamlined shape.
So, this part must be double-shelled.
At the same time, behind the ballistic missile are nuclear reactors, steam turbines, generators, etc. In order to improve underwater silence, this part is also wrapped inside a double shell.
In this way, the rear half of the submarine needs to be double-hulled. However, since the submarine is not directly driven by the transmission shaft and uses a shaftless pump, a single shell is sufficient at the rear of the submarine that is finally recovered.
As for the front of the submarine, in order to expand the volume of the living compartment, accommodate more people, and also have confidence in the steel of the submarine, the front is a single-shell structure.
Single-double shell mixing not only meets the needs of use, but also reduces the displacement. It is the most advanced design concept at present.
"From the back of the command tower to the retracted tail, this section uses a double-shell structure. You can see the drainage holes on the outside of the missile launcher." Kvasa continued to introduce to everyone: "Next, we will As for the power cabin, it is also revolutionary here. We have adopted shaftless pump technology for the first time.”
In the past, pump propulsion was also used, but the motor was placed at the tail of the submarine, and the pump jet propeller was driven through the transmission shaft. But this time, it has finally transitioned to shaftless pump propulsion. As long as the output cable is required, the motor is used in the pump jet propulsion. Inside the device, there is no drive shaft, which can naturally further reduce noise, which is an innovation.
At the same time, there is no water leakage problem caused by the failure of the tail bearing oil seal. Since the submarine has to dive to a depth of several hundred meters, the pressure below is very high, so the water leakage problem of the oil seal bearing is much more serious than that of surface ships.
This technology is not easy.
However, this has nothing to do with Kvasa. The entire set of technology belongs to Golden Sun Motor Company and Water Pump Factory. They cooperated to solve these technical problems and finally realized the shaftless pump technology of submarines.
"In this large disc at the tail, there are not only our pump-jet thrusters, but also a 40-megawatt electric motor. This is another advanced technology in our domestic submarine supporting industry. Its emergence has allowed us to We have finally reached the first place in the world in the field of nuclear submarines, far surpassing other countries!"
In the past, submarines could only use three-blade propellers, which were very noisy. Later, with the advent of advanced multi-axis CNC milling machines, they could process complex seven-blade propellers with large side angles, which immediately improved the quietness of submarines. However, this level is still lagging behind other countries in the world. The advanced France and the United Kingdom have entered the era of pumping.
Only in the case of shaft pumps, China has finally caught up with the world's advanced level, and in the case of shaftless pumps, it has surpassed it.
Now, Kvasa introduced the advanced shaftless pump to everyone, and he was very excited.
The nuclear reactor used on the 096 nuclear submarine is mature, that is, the 150-megawatt thermal power nuclear reactor used on the 095 has a power generation of 30 megawatts. Two units are 60 megawatts, of which 40 megawatts are supplied to the propulsion system, and the remaining 20 MW are supplied for internal use of submarines. This kind of surplus power is abundant.
"Because the remaining power is very large, the equipment on our submarine is well-arranged. For example, the oxygen inside the submarine can be generated by electrolyzing water, so that there is always a good air environment inside the submarine, such as fresh water. We installed it on it The high-power fresh water production equipment can produce fresh water that can not only meet the drinking needs of submarine crews, but also meet the bathing needs of submarine crews. Each person can take a bath every day, and the bathing time takes about ten minutes."
“How much water is wasted?” Someone immediately spoke.
Surface ships are generally supplied with fresh water by supply ships, but submarines can only produce it themselves and require specialized desalination equipment, which consumes a lot of energy.
Therefore, water control on submarines is also very strict. Bathing every day is a luxury, and washing once a week is normal. Bathing time must be controlled to five minutes, or even three minutes, that is, showering, applying soap, and rinsing with water. , so time passed.
If you encounter special circumstances, it is normal not to take a shower for a month. As long as the submarine goes to sea, the internal air will be smelly. , which is a great drain on the body. After landing, you have to rest for several months to recover.
Now, there are actually nuclear submarines that allow submariners to take a shower every day, and they can still take a shower for ten minutes each time!
This is so rare!
"We have sufficient power supply. We don't need to turn on the main circulation pump of the nuclear reactor during cruising. We only rely on self-circulation to have enough energy. It would be a waste to keep this energy. Of course, we need to improve the internal comfort. Needless to say It’s time to take a shower, Lao Maozi’s Type 941 nuclear submarine has a swimming pool on it.”
The emergence of the Type 941, also known as the Typhoon class, shocked the whole world, and the Americans even shivered. The underwater displacement of this type of nuclear submarine was as high as 48,000 tons! What is this concept? It is equivalent to sinking the Kiev-class heavy-duty aircraft carrier cruiser directly underwater!
If it were a surface ship, a warship with such a large displacement would have to carry several thousand people. However, the Typhoon-class nuclear submarine can only carry 160 people. It is obvious how spacious the internal space is. Therefore, there are all kinds of life and entertainment on this nuclear submarine. Facilities, restaurant, gym, lounge, sauna, and swimming pool!
It’s shocking to think about being able to swim in a submarine when you go out to sea.
Because the displacement is large and the submarine is very heavy, the Typhoon-class nuclear submarine can still launch two missiles underwater at the same time. Only its body can withstand the recoil of two ballistic missiles.
Wait a minute, doesn’t Lao Maozi not have a large plate bending machine? How was such a nuclear submarine with a width of more than 20 meters built?
The answer is of course one or two.
The huge body outside is the outer shell, and wrapped under this outer shell are two parallel internal pressure shells! If one isn't enough, get two! Only Lao Maozi can have such luxury, and the nuclear submarine he has created is so unbelievable.
The missile is stuffed between two parallel pressure hulls, so despite the width of more than 20 meters, the two pressure hulls are actually not that big. At the same time, there are some pressure hulls at the bow and conning tower. , viewed from the front, it also presents a Z-shaped structure.
Lao Maozi hesitated to build an aircraft carrier, but building a nuclear submarine is really not something that can be done for a long time.
However, only six of this kind of nuclear submarines have been built. Moreover, with Lao Maozi's current strength and lack of maintenance, these nuclear submarines will be gradually eliminated in the future.
Qin Tao felt funny when he heard that Kvasa was talking about an old man. It seemed that Kvasa regarded himself as an Oriental and forgot that he was an old man.
Nuclear reactors seldom shut down once they are opened. The things inside are long-lived. Nuclear reactors also have energy output in a low-power state. It is a waste to keep this energy. It is better to use it for other things, such as Nuclear-powered aircraft carriers can sell electricity to the shore after docking, or generate fresh water to supply coastal cities that are short of water, etc.
After a nuclear submarine goes to sea, of course, it must use the excess energy to make the submariners' lives more comfortable, so as to improve the submariners' combat effectiveness.
“Yes, our times are developing, technology is advancing, and submariners also need to improve their living environment.” Wu Shengli nodded.
In the past, everyone was very poor, and naturally they were not very particular. However, as life gradually improves, the new generation's ability to endure hardships is no longer as good as the past.
In the past, when submarine soldiers were recruited into backward submarines, they could even sleep in hot bunks, but this is no longer possible. Newly recruited submarine soldiers cannot endure the hardships of the past. It is also necessary to improve them. After improvement, , the combat effectiveness will be stronger.
“Because the internal space is large enough, there are no hot bunks on our submarines. All bunks are independent bunks, and they are bunk beds.” Kvasa continued.
Just like the bunks on the aircraft carrier are upgraded, the bunks on the submarine are also upgraded, and they are better to upgrade.
After all, this is a big thing with an underwater displacement of 17,000 tons, but it only needs more than a hundred people to operate it. The front half is still a single-shell structure, so of course there is enough space.
The nuclear reactor is at the back, separated by the missile launcher, and the personnel are accommodated in the front, so the environment will be better.
"We have installed special air purification devices in all rooms to ensure that the submarine has fresh air during the process of going to sea. We have also installed a large number of refrigerators in the restaurant so that the submariners can have a rich diet after going to sea. We also set up There is a dedicated gymnasium where submariners can go to the gym to exercise when they are not on duty."
Gym!
Everyone looked at the PPT on the screen and looked at the designed rooms. The gym is not large, but it can accommodate about twenty people to exercise in it.
The 17,000-ton monster has such ample internal space!
Everyone is very shocked.
"Unconsciously, I have already introduced you to the front, so let's continue the introduction. What I just talked about is the living area. This area is under the command tower. The layout on the command tower is similar to our current 094, although the shape is different. The same, but there is no change in the internal equipment, including photoelectric masts, snorkels, and specialized communication buoys.”
Communication buoys are a special kind of existence.
Submarines sail underwater and are hidden silent killers. Although they hide themselves, it also becomes difficult to communicate.
In the past, there was no other way of communication, which was to float up at a fixed time and send telegrams through the radio.
It would be tragic if after sending the telegram on the surface, an accident occurred during the descent. The superiors would not know that they had an accident until there was no contact at the next fixed communication time. However, it would be too late to rescue them, and the day lilies would have been cold for a long time. .
Furthermore, telegraphs would reveal their whereabouts and attract attacks from enemies, so this method has long been discontinued.
Later, long-wave radio stations began to be used, because this kind of electromagnetic wave can carry ships on the ocean and penetrate deep sea to reach submarines. However, the characteristic of long-wave is that it is very, very slow. It may take more than ten minutes to transmit a few words, and half a telegram. hours, and the construction of long-wave radio stations is complicated and the communication efficiency is very low.
In order to achieve reliable communication with submarines, buoy communication methods have emerged. This thing is divided into six types. Some directly drag the buoy for dozens of kilometers. Even if the position is exposed and beaten by a group, the submarine is long gone. That sea area, some are released directly, and the content is sent regularly after more than ten hours. In short, it is to let the submarine and the sea area where the message is sent leave.
“At the same time, we have also reserved some space. When our neutrino communication and quantum communication mature, we can replace these with more advanced communication devices.”
