The process of visiting the Typhoon-class strategic submarine is neither fast nor slow. After all, the Typhoon-class still uses traditional torpedoes as attack weapons.
But the Typhoon class has a function, which is to use submarines to deploy mines, all of which are bottom mines, so that they can be mainly deployed in enemy bases, ports and main waterways, and can be used to destroy enemy ships.
After a series of participation procedures, the highlight finally came. Under the guidance of the Typhoon-class submarine, everyone had arrived at the Typhoon-class command room. The dazzling navigation and command system here, in addition to the magnetic compass owned by the submarine,
Gyrocompass, log, depth sounder, sextant, and many other new equipment. In fact, the track autoplotter and automatic steering device are an eye-opener for visitors from all over the world.
But the next low-frequency radio and inertial navigation equipment surprised them, because the inertial navigation system of the Far East is a kind of system that can continuously and accurately provide important information such as the submarine's underwater position and heading, speed, pitch and angle.
, After using this system, the Typhoon-class submarine’s instantaneous positioning accuracy at sea reaches about 35 meters.
In addition, there are mine detection sonar and identification sonar, but according to Li Ningyu’s previous arrangements, these aspects are not intended to be disclosed in large quantities. Therefore, after the submarine arrived in the designated waters, the dive alarm bell sounded immediately on the boat, and the alarm bells in each cabin were
The order to dive came through the loudspeakers.
"Hello everyone, the Typhoon class is currently diving. Please find a fixed fulcrum. Thank you!" As the Far East commentator finished these words, the Typhoon class began to dive quickly, and the entire submarine became quiet.
.
After Li Ningyu entered the command module, the Typhoon-class captain stood steadily next to him. The submarine navigator also sat with his back straight in front of the centralized control console. He turned on the power switches one by one and instantly operated the work on the plane.
All lights are on, all indicators and instruments are working, and various data and complete charts are presented one by one.
Then the navigator will hold the joystick tightly, and as long as the captain issues instructions at any time, he will start to execute them, while the deputy navigator on the side is monitoring the work of the instruments.
At this time, the engineering technicians in each cabin who had been prepared for a long time were already busy checking various equipment and instruments. After finding no problems, they reported through the microphone: "Report to Captain, the power system equipment cabin is working
normal!".
"Report, the bow cabin is working normally!"
"Report, the weapon system equipment is working normally!"
"Report, the control equipment cabin is working normally!"
"Report, the AIP device and auxiliary equipment are working normally!"
"Dive immediately, to a depth of 200 meters!" After hearing that everything was normal in all departments, the Typhoon-class captain immediately issued the order.
"10 meters!"
"30 meters!"
"50 meters!"
"80 meters!" After just twenty seconds, the first mate in the command room looked at the diving depth seriously and counted the numbers.
“100 meters”
"130 meters!"
After hearing these words, everyone present was very puzzled, because they did not feel much vibration at all, and they did not feel the discomfort caused by the water pressure, but the first mate was already continuing: "150 meters, 180 meters
Meters, 200 meters!”.
Everything was like a flash of flint and lightning. If they hadn't heard the chief mate in the command room say with their own ears that it had dived to a depth of 200 meters, the people visiting from various countries would have thought that the submarine was still slowly submerging, but it seemed
Some people still don't believe that they can dive to 200 meters in such a short time.
So Norsky, the minister of the Tsarist Empire, expressed his confusion loudly: "Oh my god, this is impossible. I just checked the time. From the beginning of the dive to 200 meters, the Typhoon level only took one minute, that is,
Three meters per second, we must know that our Tsarist Russia
The Empire's latest Shark-class attack submarine takes at least 25 seconds to dive from the surface to 60 meters. The Shark-class is only 500 tons, but the Typhoon-class is 8,000 tons. How can such a large submarine be more agile than the compact Shark-class?
!".
To be honest, the Typhoon-class hull is too large, so it is definitely easier to be discovered by the enemy than a small attack submarine. However, this does not mean that the Typhoon-class dive speed will be slower than that of a small attack submarine. That is
Because the Typhoon class has four water storage tanks, while ordinary attack submarines only have one.
After Norsky, Minister of the Tsarist Empire, raised questions, many people present lowered their heads and started whispering, but Li Ningyu just smiled and motioned with his eyes to the captain on the side to continue diving. This time the target depth was 300 meters.
It is also the largest diving depth of typhoon level.
Pressure can be divided into two definitions: mental and physical. The physical definition has objective attributes, so looking at the depth of the dive, the officer continued to read without distraction: "210 meters, 215 meters, 220 meters...".
From a psychological point of view, stress is a cognitive and behavioral experience. Although Li Ningyu did not prove that the typhoon level really dived to more than 200 meters, a tense atmosphere still spread. After all, not everyone
Many people do not believe that the typhoon level has dived to more than 200 meters and is still diving.
However, as the depth of diving becomes larger and larger, the pressure of the seawater itself becomes smaller as the force-bearing area becomes smaller, and the pressure effect becomes more and more obvious.
Especially as the pressure and gravity increase, the gravity caused by the mutual squeezing between the typhoon level and the seawater begins to have an effect. Many people have already experienced tinnitus caused by pressure.
Finally, after a minute, the first mate said seriously: "Reporting to the captain, the Typhoon One is currently diving to 300 meters. Please give instructions!".
"Stand where you are!" the captain said seriously to the first officer in the command room.
Following the conversation between the captain and the first mate, Li Ningyu adjusted his clothes and said with a smile: "Welcome to the depths of the sea, let's enter the third part of the tour.
Rapid resurfacing, please be ready!"
As soon as Li Ningyu finished speaking, the submarine staff on the side immediately distributed a special necessary material for Typhoon-class submarines called pressure-reducing cotton, which is stuffed in the ears to prevent discomfort caused by huge changes in pressure.
However, some people don't seem to believe that typhoon level can dive to 300 meters, so they don't appreciate Far East's kindness. However, at the request of the staff, most of them were stuffed with decompression cotton.
"Float quickly!" Li Ningyu gave the order after the staff completed the distribution steps.
"yes!"
"Order! Immediately surface quickly, both vehicles go at full speed, and all water storage tanks are fully drained!" After receiving the order, the captain conveyed Li Ningyu's order.
The next second, everyone on the Typhoon-class strategic submarine felt the so-called sense of movement before, because at this time the Typhoon-class was moving upward at high speed, and naturally there was a huge pressure gap that followed.
