Submarines in the sea mainly rely on sonar to judge the azimuth and distance of surrounding objects. Without radar, submarines are equivalent to myopia, but if sonar fails, submarines will immediately become blind.
Seawater is affected by temperature, salinity and depth, and there are many regular and irregular density-cline layers in the world's oceans.Sound waves are reflected on the surface of the climatic layer to form a long-distance sound channel, and the energy of the sound wave will be greatly attenuated during this process. It seems that the surrounding layer density is too thick, which shortens the detection distance of the sonar.
That's why the submariner manning the pocket submarine didn't dare to speed up the submarine, because even a pocket submarine weighs dozens of tons. From seeing an obstacle, it is almost impossible to stop the submarine at a distance of several hundred meters. It is impossible. Anyone who has studied basic physics should know that the greater the weight, the greater the inertia, and the harder it is for the object to change its original behavior.
The captain frowned slightly: "Contact the people above and ask them to report the location to us, then turn around and go to the next possible location of 303."
"Yes"
Four or five operators nodded in agreement and cooperated with each other to steer the submarine.
Submarines are more complicated to operate than airplanes. There are more than a dozen various data sheets alone, and at least two people are required to operate the steering position, as well as observers and counters.
As the submarine turned, a sense of weightlessness spread throughout Chen Yu's body.
To be honest, sitting on this thing always felt a little dangerous, and even he felt uneasy.
The submarine moved forward, traveling about 600 meters forward, and suddenly there was a bang.
The ship shook violently and sank rapidly. This time, the feeling of weightlessness was much stronger than before. It was as if the traction wire was suddenly broken while taking the elevator, and the blood all over his body was floating upwards.
The operator's face was pale, and he instantly realized what had happened.
Sink! ! !
This is simply a nightmare existence for submarines.
If the seawater cline layer is in a state of high density in the upper layer and low density in the lower layer, a negative density gradient cline layer will be formed, which is called "sea cliff"!When a submarine is navigating underwater, once it encounters a sea cliff, it will fall sharply to the bottom of the sea, which is called "falling deep".The effective diving depth of most conventional submarines is 300-500m. When the submarine falls below the safe diving depth uncontrollably, it will be damaged by the huge seawater pressure and cause an accident.
In 1963, the U.S. Navy's "Thresher" nuclear submarine was killed in such a dangerous situation. All 129 crew members were buried in the belly of the fish.
It is generally difficult to detect sea cliffs, and this technology is still immature even in the era of Chen Yu ten years later.
The captain's face also changed drastically. As far as he knows, so far, no submarine has survived the sea break.
Depend on!
Chen Yu cursed loudly, what a fucking disaster, he felt that God was embarrassing him, didn't he just want to complete a hidden plot, as for fucking want to kill me.
He stepped forward and threw the operator aside, and started operating various instruments by himself.
"What are you doing!" The captain stepped forward and shouted to stop him, but when he saw Chen Yu's operation, his outstretched hand suddenly stopped in midair.
He discovered that Chen Yu's operation was actually correct!
Turn off the main motor, close the cabin, and avoid the short circuit of the whole boat due to water ingress...
"Damage control alarm, supply air to all water tanks!" Chen Yu hurriedly said, and he looked at the captain beside him: "Don't f**king do it, do you want us to die here together!"
The driving skills he acquired not only include driving cars, ships, submarines, airplanes, trains, high-speed rails, and rockets. If he wants to extract the knowledge in his mind, he can take it out at any time and master it quickly.
With the addition of master-level skills, even this lieutenant colonel who has been a captain for more than ten years may not be able to match him in his understanding of ships.
The captain also reacted quickly, and shouted to the submariners behind him: "Open the emergency air supply valve, supply air to all water tanks, and turn off all other useless valves!"
The sound in the cabin was chaotic. Due to the loud sound of the submarine falling, many submarine soldiers could not hear the words of the people around them at all, and could only rely on the instincts they had trained to take various actions.
Ten seconds!
The air valve is opened, the water tank starts to supply air to provide buoyancy, dozens of electrical appliances are quickly shut down, and all the fresh water stored in the cabin is drained to reduce gravity.
After 2 minutes, Chen Yu and the soldiers on the submarine completed more than 50 operations. The 3000-ton Song-class submarine finally stopped sinking and began to slowly rise.
It wasn't until the submarine surfaced to a position more than 200 meters below sea level that everyone breathed a sigh of relief.
"Go and check to see if there is any damage to the equipment." The captain wiped the sweat from his forehead and said to the subordinates beside him.
After about five or six minutes, the inspecting soldiers came back.
"Report to the captain, due to the low depth of the dive, only a small part of the pipeline on the submarine was slightly squeezed and deformed, and other places were not damaged."
The captain let out a long breath.
He looked at Chen Yu, expressing gratitude and admiration: "Thank you, comrade. If it weren't for your reminder, I'm afraid we would all be in trouble, and I am ashamed of the country's trust in me."
"Chuanzi, are you a soldier who graduated from a military engineering university and joined the army? You are a genius!"
Long Baichuan's brain is still a little dazed until now, he didn't expect that such an accident would happen to him for the first time when he was building a submarine, he was stunned for a moment when he heard the captain's words.
He couldn't understand all kinds of information about Chen Yu. The students of Dagong, who majored in heavy machinery, have nothing to do with submarine hair. Moreover, they can operate submarines and make emergency responses based on the knowledge in textbooks. It is the Arabian Nights.
"No, I studied on the Internet. I have been particularly interested in military affairs since I was a child, especially submarines. I learned relevant information and made some bold assumptions after seeing the problem of sinking." Chen Yu knew it was not good. Explain, but if he doesn't stand up today, everyone present will die.
He simply changed the subject as much as possible: "I didn't do anything, but I just made a few suggestions. The main reason is the tacit cooperation and timely response of the brothers. It seems that the training is not less difficult on weekdays."
This speaks to the hearts of the submarine soldiers around. Their daily training is not too tiring, but it is really hard!Often work under high oxygen concentration and high atmospheric pressure, the damage to the heart and brain is not serious.There are also some perverted psychological training. A person lives alone in a narrow and dark room, can only eat, sleep and go to the toilet. There is no one to talk to, and there is no sunlight. Some soldiers are often trained to depression.
"External network?" The captain was stunned for a moment. He also knew that some countries made public their knowledge of some military machines, and they were all superficial contents. Based on these contents, they could be associated with so many things. The young soldier in front of him Truly a genius!
"Old Li, can you continue to carry out the mission?" Long Baichuan asked.
Captain Li regained his composure before realizing that they still had unfinished tasks.
"There is no big problem, the negative density gradient is small, and the emergency measures were taken in time. It only sank to more than 1000 meters, and the submarine was almost undamaged. After adjusting the air pressure, continue to set off."
After about two or three hours, they went all the way to another location.
After waiting for nearly an hour.
The three to forty-meter-long black shadow reappeared.
"Maintain relative speed and launch the iron hook."
The speed of the submarine changed and it circled behind the 303 submarine.
"Ding!!"
A pair of iron hooks shot out from the bottom of the submarine, hooking 303 tens of meters ahead.
"Slow down slowly, drag it to a stop, and break the iron hook immediately if there is an accident." The captain was also very excited. This is the legendary ghost submarine. The United States and Russia have spent huge sums of money for so many years and failed to capture one.
The Song-class submarine slowly slowed down, but the 303's traction force was surprisingly strong, and it was able to pull the Song-class submarine that was three or four times its weight to continue moving forward little by little.
"Captain, do you want to pull back?"
"No, if the iron hook breaks, it will easily cause the submarine to tilt and hit the surrounding things."
It's like a tug-of-war. If all the people on one side lie on the ground and use gravity friction to block the pulling force on the other side, the rope will break, and the side pulling the rope will fall backwards, but if both sides pull back, the rope will fall. If it is broken, people on both sides may be injured.
"Or I'll go out and look on it."
Chen Yu said.
"Get out?" The captain shook his head, "The current position is more than 200 meters deep, and the water pressure is nearly 300 million pa. There is no atmospheric pressure diving suit on the submarine. You can't hold it. I have already notified the salvage team. come over."
"It's so-so, more than 200 meters." Chen Yu said with a flat face: "I can dive to 100 meters with bare hands when I am in the sea training ground."
What!Hand diving can dive to 100!
Captain Li was a little dumbfounded. The record of their submarine force's bare-handed diving is only more than 80 meters, and the world record is only 113 meters.
He looked at Long Baichuan with questioning eyes.
"I don't know about this, but he is the soldier with the best personal combat ability in our marine corps. You might as well trust him once." Long Baichuan said.
Chen Yu has created too many miracles. Before him, many people thought it was impossible. A recruit defeated the legendary veteran, led the recruit rookie to destroy the experienced special team, and escaped from the encirclement of hundreds of pirates. When the submarine sank, a quick emergency response saved the entire crew...
The captain touched his chin and thought for a moment, then nodded, "Okay, but be careful, if you can't bear it, come back immediately."
"Um"
Chen Yu entered the changing room, put on an ordinary diving suit with a ventilator, and came to the bottom hatch of the submarine. After the hatch above his head was closed, it immediately became a completely enclosed space.
With the flash of the signal light, the hatch under his feet slowly opened, and he also fell weightlessly into the sea in an instant.
In an instant, the pressure of the sea water rushed towards his face, as if a huge palm was holding him firmly.
Chen Yu waved his limbs with difficulty, dragged on the iron chain, and slowly swam to 303.
The water pressure of this fucking 200 meters is definitely not a joke. Even if he mobilizes his spiritual energy and distributes it to his whole body, it is still very difficult, but it is not to such an extent that it is difficult to move an inch, so he can barely swim.
Four or five minutes later, Chen Yu successfully came into contact with the most mysterious clue item in the show-the deep sea ghost 5 submarine.
This kind of submarine is an old-fashioned submarine, which continues the practice of Russian submarines, and has glass windows installed on the command cabin. 303 should have been impacted, and the window of the command cabin was broken. Chen Yu cleaned up the glass fragments from the window one by one, so as not to scratch the diving suit when he went in later.
Through the window, Chen Yu saw the scene inside. A blue transparent figure sitting on the operating position was watching him. Chen Yu just glanced at it and didn't take it seriously.
This thing can be regarded as a kind of ghost. To be precise, it should be a spirit. They will only repeat what they have been doing before they were alive, and they are not aggressive.
The reason why this ghost submarine can move forward is also because they have been using their own strength to cooperate with the ocean currents to push the broken submarine forward.
Chen Yu swam into the cockpit and roughly observed the inside of the submarine. These equipments were broken. After all, they had been soaked for decades. He wanted to find the cabin where drugs and Chinese antiques were hidden, but he found many The cabins were still tightly closed and could not be opened, so I simply gave up.After swimming around, he didn't find anything interesting, so he took out a large stack of exorcism charms from the system space, which he had prepared for this day.
These lavender exorcism talismans shimmered and quickly turned into fly ash. At the same time, all the faint blue transparent figures on the submarine gradually turned into dots and disappeared in the sea water. This ship was sought by various countries and many armed organizations. The mysterious submarine that has been waiting for many years has finally stopped.
"Ding! Congratulations to the host for completing the hidden task, solving the mystery of the clues and items in the whole show, and rewarding a random general talent draw.
Extracting...
Ding!Congratulations to the host for getting the talent: precise shooting, one hit. (From the main plot character: Wuyun Gerile)"
