Chapter 1,178 The inside of a 17,000-ton nuclear submarine is so big!
Kvasa thought of the red empire in the past. Only that red empire could build such a powerful submarine. No, the red empire couldn't build it either. After all, the red empire didn't have such a large-diameter bending machine!
Kwasha is grateful to be able to come to the East. Only in the East can he see the miracles one after another!
Not to mention the aircraft carriers outside, they are not in charge of them after all. In terms of submarines, Dongfang has reached a world-class level!
"Kvasa, please introduce it to the leaders." Qin Tao walked to him with a smile: "What kind of advanced technology is used on this submarine."
"Okay, let's start from the beginning. The sonar on the bow is currently the largest submarine sonar in our country. It mainly uses passive methods and can detect Los Angeles-class submarines a hundred kilometers away." Kvasa knew these indicators well.
Immediately he started to introduce it nonstop.
I think back then, the Los Angeles-class submarines were what the East looked up to, but now, the East can finally easily leave the Los Angeles-class submarines behind. Even the most advanced submarines in the West cannot compete with the East's submarines!
"A side sonar array is used on the side of the hull. Since the hull is longer, it can accommodate more arrays. The Los Angeles-class submarine can be found at a distance of two hundred kilometers and can be accurately positioned at a distance of one hundred kilometers.
, you can launch anti-submarine torpedoes at any time to kill your opponent.”
"Can you kill your opponent a hundred kilometers away?" Qin Tao was a little surprised by this. He had never heard of it. The most advanced torpedo in China at present is probably the Yu-10. This torpedo uses HAP three-component propulsion.
It uses agents and long-range fiber optic guidance technology, and its maximum range can reach 60 kilometers. It is already incredible. A torpedo with a range of hundreds of kilometers? I seem to have never heard of it.
Wu Shengli smiled. His son-in-law was a shipbuilder, and he had never been exposed to other subsystems. Moreover, he usually sat in the office and was aloof. He had not looked at many design drawings carefully, so he definitely didn't know.
"We have developed many advanced torpedoes in China. After the Yu-10, there is also the Yu-11. This torpedo is an electric torpedo that uses the highest energy density lithium-ion battery pack, which is used in our Pacific Electric Vehicles.
That kind can be equipped with different battery packs according to different targets. If four batteries are used, it can have a range of more than 100 kilometers."
Torpedoes mainly have two kinds of power: heat engine and battery. The heat engine power is relatively direct, but bubbles will be generated during navigation, which is not conducive to concealment. The battery power is very concealable, but the energy density is limited.
The initial torpedoes used lead-acid batteries, which were good if they could travel twenty kilometers. Later torpedoes began to use silver-zinc batteries, with a range of thirty or forty kilometers. If you want to continue to increase the range, you must use more advanced batteries.
What’s more advanced? Lithium-ion batteries, of course!
The energy density of silver-zinc batteries is about 100 to 150Wh/kg, which is similar to the first generation of lithium batteries. However, with the rise of electric vehicles, the energy density of lithium batteries is also constantly improving, and now it has reached 200Wh/kg. Last year
At that time, Pacific Electric Vehicles launched a new 4680 battery, with a single energy density of 300Wh/kg, which means that the range of the torpedo can be doubled by just changing the battery.
But... Qin Tao frowned: "Is safety guaranteed?"
"Of course there is no problem with safety, and we don't need it to be charged and discharged repeatedly," Kvasa said.
The main problem with lithium batteries lies in charging and discharging. Overcharging or discharging will cause problems. When used on submarines, they are disposable. Under the management of advanced battery control systems, the occurrence of accidents can be greatly reduced.
Qin Tao still frowned: "Don't be afraid of ten thousand, just be afraid of the unexpected. I don't recommend our expensive nuclear submarines to use this kind of torpedo. It is better to use silver-zinc batteries honestly."
When Qin Tao deceived the people on the island, he introduced how useful lithium batteries are and asked their submarines to replace lead-acid batteries with lithium batteries. If they exploded and caught fire underwater, that would be fine. However, what would happen to his own nuclear submarine?
You have to be careful. The tragedy of Lao Maozi's Kursk is right in front of you. He used an easily explosive torpedo and ended up destroying himself.
Silver-zinc batteries are early rechargeable batteries with slow charging speed and low capacity, but they are safe.
"Actually, the development of nuclear-powered torpedoes is the direction." Kvasa said: "Nuclear-powered torpedoes have a strong endurance, not to mention one hundred kilometers, ten thousand kilometers, no problem, and they can also be concealed. If they are equipped with nuclear warheads... the enemy
The fleet was destroyed and no one knew who did it."
Lao Maozi has a similar nuclear torpedo, called Poseidon. It uses a liquid metal nuclear reactor and can sail at a depth of one thousand meters. The enemy is not aware of it at all. Lao Maozi considers it a big killer.
However, this thing has not been tested in actual combat, and no one knows its specific performance. Everyone has heard of a lot of accidents involving liquid metal nuclear reactors.
"Okay, let's not talk about this anymore. We are here to see the submarine today, not to see the torpedoes." Wu Shengli said, looking at the submarine: "Can we go inside and have a look?"
The submarine has been built and is waiting to be launched. However, in order to keep it confidential, the submarine launch will be done at night. There is still a while, so why not go inside the submarine and have a look!
"Of course you can, but because the interior of the submarine is too complicated, you must follow closely and don't look around, otherwise you may be left behind."
"Come on, let's get off the stage."
The submarine's command tower is too high to get in from there. You can just get in through the hatch cover in front of the submarine. There is a platform next to it and you can just climb up.
However, before entering, the logistics staff waiting aside gave each leader a small device with only a small screen and no other information.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "What is this?"
"Radiation meter." Qin Tao introduced: "Although the nuclear reactor will not be started until the nuclear submarine is launched and moored for testing, the nuclear fuel has already been stuffed in, so there may be accidents."
The nuclear fuel of a nuclear submarine is added when it is built. If the nuclear reactor and the nuclear submarine do not have the same lifespan, complex fuel replacement operations will be involved in the process, and it will often need to be overhauled in one or two years.
"Of course, if some leaders are not feeling well, they should not go in."
Qin Tao's words had the opposite effect. Who can give in at this time? You have to go in and have a look, and this may be the only chance.
So, a group of leaders wore radiation meters, walked up to the stage with their heads held high, and then got into the submarine.
"Everyone, leaders, follow me. Let's go to the front first. In front is the torpedo room."
The diameter of the pressure hull is 13.4 meters, and the advantage is that the interior is very spacious! Especially when they came to the torpedo room, everyone was stunned by the spacious interior.
The width of an ordinary three-bedroom house with one living room in the east-west direction is only eleven or twelve meters, and its surface width of thirteen or fourteen meters is almost as large as a flat floor!
"It's no problem to have a meeting here. Hey, why are there more beds here?" Immediately, the leader discovered something: in this wide torpedo cabin, there were actually three rows of beds, just like the earliest Datong bunks.
The row can sleep about ten people, and each person can be assigned a bed more than one meter wide!
The torpedo room of the submarine is far away from the power cabin and is very quiet, so it is a place that many sailors like to come. In the past, domestic submarines had small space. After going to sea, many sailors hung hammocks in the torpedo room to sleep. But later, as submarines
With the increase in intelligence, fewer and fewer sailors are needed, and the space of the submarine is getting larger and larger. Everyone has a place to sleep, and there is no need to hang a hammock here.
Why is it now being used as a temporary sleeping place?
"Leader Wu, after the submarine is launched, it will conduct a mooring experiment. After the mooring experiment is completed, it will go to sea. Our technicians will go to sea with the sailors, so the original beds will not be enough, so we set up a folding bed here in advance.
"These folding beds are internal equipment of the submarine and can be put away when not in use. If other personnel are carried on the submarine in the future, they can also have a place to sleep," Kvasa said.
One of the beds belongs to Kvasa, and Kvasa will also participate in the sea trials of this submarine!
All the leaders stood in the torpedo room, and they still felt that the interior was relatively spacious. It was like having a meeting in a large conference room. Everyone looked at the various fixing racks and imagined what it would be like to be filled with torpedoes in the future.
Looks like.
Since the bow sonar occupies all the space, the torpedo launch tube is designed to the side and is also tilted inside. The guys looked at the launch tube, studied it some more, and then walked to the back.
"This is the weapons launch console." Kvasa continued to introduce.
All of them are vertical cabinets, and the most surprising thing is that these cabinets are actually installed on rubber shock-absorbing supports. I originally thought that it would be enough for engines and the like to be mounted on shock-absorbing devices, but I didn’t expect that these cabinets also have
Shock absorbing device.
Everyone was surprised when they saw it.
"Going through here, we walked downstairs. Below is the living area. There are sailors' dormitories and a restaurant. In addition to providing food and drink for the sailors, the restaurant can also be used as a place for leisure and entertainment in their free time. You can play chess in it.
, you can read and study. We have installed a TV inside, so everyone can watch the programs they want."
After going down, everyone was shocked. This restaurant is really big!
The advantage of increased drainage is that it makes life and entertainment easier, and proper relaxation helps to work better.
Since submarines work in three shifts, the submarine's restaurant only needs to be able to meet the dining needs of one-third of the people. The restaurant in front of you is enough to satisfy hundreds of people on the submarine dining at the same time!
How many people are there in total on the nuclear submarine? Only about a hundred people!
Lao Maozi's Typhoon-class nuclear submarine is the largest nuclear submarine in the world and also has the largest number of people, with a staff of 175. The Yankees' Ohio-class nuclear submarine has a staff of about 150. These are submarines from the Cold War era. Now, with the automation
With the use of equipment, the number of people required on nuclear submarines is also decreasing. Lao Maozi's Beifengshen nuclear submarine only requires 107 people, one less than Liangshan's 108 generals.
096, a monster with a displacement of 17,000 tons, only needs about a hundred people. Therefore, this restaurant means that it can hold meetings for all crew members. Of course, this is only in the moored state. If
When going to sea, there are always some people who need to stay at their posts, so the restaurants here are definitely sufficient, and even redundant.
It can be said that the location of this restaurant can even be fixed. Everyone has their own special place. Whether it is eating or reading and studying, this restaurant is also a place for leisure activities. If it were not for the large drainage volume, it would really be impossible to waste so much.
ah.
Looking at the place in front of them, everyone was filled with emotion.
"There is a huge cold storage in the back." Kvasa continued to introduce to everyone: "Within one month of going to sea, the crew can eat a variety of fresh vegetables and fruits. Starting from the second month, they can eat a variety of easy-to-store foods."
Food, after three months, you can continue to eat canned food.”
The food standard for submariners is the same as that of pilots, because the conditions for their survival are the worst. Once they go to sea, they may be underwater forever, in the dark. If they do not have enough psychological quality, they may suffer from mental illness. Of course, diet
It cannot be shabby.
However, due to limited conditions in the past, after sailors went to sea, all kinds of food would fill up all the space. Even around the beds where they slept, there were things like sausages hanging around. Every unused corner had to be used.
When you get up, the first thing to be consumed is fresh things, fruits, vegetables, etc. After these are consumed, you start to eat things like potatoes. Sometimes, you also have to eat moldy things.
What if there is a special cold storage to store food? That would make people extremely emotional. This condition is great!
The 17,000-ton underwater beast has such a large space! It can feed about a hundred people. Of course, it also has enough space to store all kinds of grains, vegetables and fruits. It has a special cold storage and can eat it for a month.
The fresh fruits and vegetables are quite good!
"Because it is a nuclear submarine, it has abundant power, so submariners can have hot meals at any time." Kvasa continued.
In the past, diesel-electric submarines had no need to even think about it. When the snorkel was deep, the battery had to be fully charged in the shortest possible time. When underwater, the power of the battery had to be conserved. Therefore, when on the submarine, one often needed to eat cold water.
Rice, everyone in this situation has a deep understanding of it.
A nuclear submarine is enough, not to mention that this kind of nuclear submarine has two nuclear reactors. Even if it sails at full power, there will be a certain power surplus. Three meals a day, all are hot!
"The dining space is very large, so the accommodation space should also be large, right?" Someone thought of something.
"Yes." Kvasa said: "In terms of accommodation, our submarines not only cancel hot bunks, but also have bunk beds."
In the past, the internal space of submarines was limited, so the sleeping space was also very small. Not only were there three-person bunks in the upper, middle and lower bunks, each person could only get in and could not raise their head. Moreover, this bunk could not be occupied all the time.
Each person is assigned a sleeper, and within a day, the three people take turns switching. There is always someone sleeping in the sleeper, so it is also called a hot bunk.
Now, with the increase in displacement, the space inside the submarine is very large. Therefore, the sleeping berths are all personal, where personal belongings can be placed, and they can also be converted into bunk beds. In this way, the vertical space is large, and people can at least sit up.
, the feeling of sleeping will be much better.
"Come on, let's go take a look." Everyone was excited.
The places for eating and sleeping are all next to each other. After everyone entered, they saw the separated "single rooms." The single rooms were separated by vertical iron plates. There were two bunk beds on each side of the iron plate.
There is an aisle in the middle of a single room and beds on both sides, thus forming eight-person rooms.
At the end of the partition, there is a foldable desk for the crew to read, write and use a computer. This spacious space is amazing.
"Eat well and sleep well so that submariners can have physical strength." Wu Shengli said with emotion: "On a submarine like ours, even if we stay underwater for three months, the crew can endure it. Under normal circumstances,
, I only spent a month submersing, and my life was wonderful every day.”
You can eat fresh vegetables within a month, which is enough. After all, under normal circumstances, it only takes about a month for a submarine to go to sea, which is generally not too long. After nuclear submarines were built, all countries wanted to have the most fun.
Long submersible record, Lao Maozi couldn't stand it after staying underwater for 45 days. The Americans stayed underwater for 84 days. As for us, in 1985, a 092 submarine set a record of 92 days, and the crew members all
It was walking down.
At that time, it was used to break records, but now, it can be regarded as a normal mission. It is no big problem to go to sea and stay in such a comfortable environment for three months.
During World War II, German U2 submarines often went to sea for more than 12 weeks at a time, but most of the time they were in a floating state. Sailors could take a few breaths of fresh air in the control tower or on the deck, and feel like they were completely underwater.
no the same.
"What's that little cabin over there?" someone asked, pointing to a strange-looking cabin.
These sleeping areas are separated by partitions, but the cabin has a door.
"That's the shower room over there." Kvasa opened the door: "There are six nozzles inside, which can accommodate six people taking a bath at the same time."
Take a shower! You can actually take a shower on a submarine! Although this design has been reported before, but now, hearing it with your own ears and seeing it with your own eyes, it still makes people feel incredible.
Everyone looked inside. The space was not very big, and there was no place to change clothes, which meant that you had to go in naked and come out naked after washing. However, there were only men on the submarine, so there was no need to be too taboo. At the same time, six
Individually, if each person takes ten minutes, he can wash more than thirty or a hundred people in one hour. He can wash them in three times, which just meets the needs of three shifts. After getting off work, he can take a shower and feel comfortable again.
Just sleep on the ground and three months of underwater life will pass quickly!
