Chapter 407 Diving to a depth of 600 meters? I do not believe!

   "Recharge our Jiaolong immediately!" Qin Tao climbed out of the spherical cabin of the Jiaolong and shouted to the people next to him: "Before it gets dark, we can hoist a nearly 20-ton wreckage!"

   Among the wrecks of the Dingyuan ship, this is the largest one. Qin Tao has already aimed at this wreck.

The popularity of the Aircraft Carrier Park cannot continue. After all, after seeing it once or twice, it will be boring to go up again. Therefore, we have to add something new. The museum of the Dingyuan Ship will be the focus of attracting tourists next. He is very excited. expect.

  In order to charge the Jiaolong, an additional MTU generator set was installed near the crane. At this time, the diesel engine had started, and the thick cable was inserted into the charging port of the Jiaolong, and the charging was proceeding rapidly.

Qin Tao looked at the Jiaolong, full of joy. If the divers were sent down, the movement would be too slow, it would take a long time, and it would take a day or two to clear the mud. Able to complete salvage work.

etc!

  The expression of the big guy seems to be not quite right.

  Our side has made such a big discovery, shouldn't the big guys come over to express their congratulations? Now, why do everyone look so outraged?

   "Zhengyang, what happened?" Qin Tao asked.

   "Captain Liu won't let me speak."

   "Then do you listen to him or me? Is it I who will pay you, or he who will pay you?"

   "We received a telegram, a distress telegram from 403."

  403?

  Qin Tao's expression changed immediately: "Where is it?"

   "It's about two hundred nautical miles away from us."

   "Then what else to say, drive over!"

   "But, aren't we salvaging the Dingyuan ship?"

"The wreckage of the Dingyuan ship is in the water, and it can't escape at all. It can be salvaged sooner or later, but the rescue mission is urgent, we must go there quickly!" Qin Tao said: "Also, call the J-31 fighter jet, Wait at the nearby base, and if necessary, fly to our deck."

  The area of ​​the helicopter platform at the tail of the Nancang is very large, and two helicopters can be parked. Moreover, if there is only one helicopter, the front hangar can be retracted, leaving a larger takeoff and landing platform for the helicopter.

  If you are a skilled pilot, you should be able to land the J-31.

  Even if the landing will ablate the deck, I don’t care, the big deal is to go back and re-weld it again!

  However, when it's time to make a move, you can't sit still.

   Qin Tao said, and quickly walked towards the deck.

   "Boss Qin, we can't do this, we need to wait for orders from our superiors." Liu Yong said: "Now, if we act without authorization, it may disrupt the overall deployment."

"Right now, this comprehensive supply ship is still in sea trials. We drove it to test its performance." Qin Tao said: "Besides, we are still carrying the Jiaolong. I have a good way to do it now." .”

   Jiaolong, a good way?

   Liu Yong opened his eyes wide when he heard Qin Tao finished his plan. If this is the case, he can really act, but he still needs to report to his superiors!

   "We will start at full speed now and head towards the sea area where the incident occurred, but at the same time, we must also report to our superiors and obtain their permission."

   This is already considered a cut first.

"All right."

   After all, Nancang is a supply ship with a maximum speed of only 16 knots, so its movements are not fast. By the time it reaches the sea area where the incident occurred, it was already midnight.

  There was a roar in the sky, that was the dispatch of the fixed-wing anti-submarine aircraft. On the surface of the sea, there was a sound of plop, plop, and the sonar buoy was dropped into the sea.

  The situation is very dangerous.

   "Boss Qin, you can't go down, it's too dangerous!" Seeing that Qin Tao wanted to get into the Jiaolong again, Xu Zhengyang immediately stopped him.

"During the day, I was still lamenting the history. Our outstanding sons and daughters of China have gone on and on, and finally established a new China. Now, it's my turn. Am I going to be a coward?" Qin Tao said: "Besides, There's no danger here, we're just going to do a square dance underwater, what's there to be afraid of? You can't hold me back at such a critical moment."

   "Well, Mr. Qin, I'll go together, even if it's in the back, if there is any danger, you have to..."

  Xu Zhengyang originally said that he would die together, but he didn't say it in the end. This is too unlucky.

Qin Tao smiled: "What do you want? I already have a son, so I'm not afraid even if it's glorious. Zhengyang, you don't have a wife yet. What nonsense are you talking about? Why are you making such a fuss. Come up if you want to."

  Xu Zhengyang carried the tape recorder and got into the rescue cabin at the back. The original three-person team was still in front. This deep-diving lifeboat entered the sea again, but this time it was carrying cables.

  The deep-diving lifeboat has its own power, but it can only rely on battery power, and the use time is very short. Therefore, if a cable is pulled from the mother ship, it can greatly increase the underwater endurance time.

  However, the deep diving lifeboat is originally very flexible. If you drag a cable, it will greatly limit its maneuverability.

  So, when searching for the wreckage of the Dingyuan ship in circles on the bottom of the sea, you can't hang the cable, but for the current operation, it is the most appropriate to hang the cable.

  The deep-diving lifeboat sank slowly in the sea water, maintained at a depth of 50 meters, and then sailed westward for three nautical miles, which is the maximum length of the cable.

   "Zhengyang, get ready to turn on the tape recorder!" Qin Tao shouted back through the intercom.

   "Understood, received!"

   "Attention, the volume is from low to high! Take your time and don't rush!"

"clear."

  Xu Zhengyang turned on the tape recorder, the special tape began to rotate, and the special sound was transmitted through the speaker, vibrating the side wall, and then transmitted through the side wall to the sea water outside.

   On the anti-submarine aircraft, the sonar operator who was listening immediately became excited: "I found it, I found it! The sound gradually became louder, indicating that it is approaching and it is heading east!"

  Xu Zhengyang slowly turned up the volume, and the sound from the sonar buoy in the sea water was from far to near.

   It was getting louder and louder, and when Xu Zhengyang's volume was turned up to the maximum, Qin Tao had to put on headphones.

  It’s too loud, it’s definitely the volume of a square dance!

   This time, not only the anti-submarine aircraft in the sky, but also the bow sonar of the nearby warships were captured.

  A famous sonar operator is very excited.

   "Comparing with the database!"

   "That's right, it's the Han class!"

   "It's so loud, it must be going full speed!"

   "Yeah, it's a sea tractor!"

   "Follow it, follow it, don't lose it!"

   "Oh, I guess, it is approaching that surface ship at full speed, and it wants to use the cover of that surface ship!"

   "It's a trick to hit the east and the west. We thought it would return to the west, but it turned out to be moving east!"

  In two hundred meters of water, the sonar operator of boat 403 also heard this familiar voice.

   "Is it our companions? How could they do this? We can't put our companions at risk!"

   "That's right, we're going full speed ahead too!"

   "Don't talk, keep silent!" The captain clenched his fists: "Now, return at a low speed at a speed of two knots!"

  Boat 403 headed westward and continued to return. On the east side, the Jiaolong was turning on the sound all the way underwater. It was like dancing a square dance underwater, and they attracted everyone's attention.

  On the water, everyone on the supply ship Nancang was listening silently, listening to all sounds.

   "Accelerate the dragging of the cable!" Liu Yong gave the order.

   Only relying on the volume of the Jiaolong's square dance, it is impossible to completely simulate 403. After all, the underwater speed of the Jiaolong is only a few knots. With such a big movement and full power, it only runs a few knots. There must be a problem!

   Therefore, the Jiaolong has to be dragged by cables to continuously increase its speed.

   "The cable is half received!"

   "Slow down the cable receiving speed, let's speed up!" Liu Yong gave orders one by one.

  These are all Qin Tao's plans, and he will attack the west, encircle Wei and save Zhao, and put on a gorgeous show!

   And, it went very well.

   Among them, the tape is the most important thing. They were delivered by a helicopter while they were on their way. Using a helicopter to deliver tapes is definitely a luxury, but the effect is just now, and it is definitely worth it!

  Any submarine will make sounds, and they are completely different sounds, some are like sea fish spitting bubbles in the water, and some are like driving a tractor in the sea. Their tape was specially used for sonar training, and it contained all the voices of 403.

  Finally, the cable was only 100 meters away, and it stopped. The big guys climbed down and put their ears on the deck, and they could hear the unique and beautiful sound below.

   "Zhengyang, turn down the volume by half, and the speed of the underwater ship is more than ten knots, that's it."

  At this time, the sonar operators in the sea area were very excited: "Sure enough, it got under the belly of that ship, and it is still sailing eastward. Let's follow and see where it can go!"

  The anti-submarine aircraft continued to fly over, and even flew to the sea area in front of the Nancang, throwing sonar buoys. This kind of action was quite unfriendly, but everyone on the Nancang was extremely excited.

  The more they chase after, the happier they are.

   After a day's delay, they still have a big move!

   When the time comes, let them be completely surprised and desperate!

   Underwater, the Jiaolong is still moving.

The cables above provide them with unlimited battery life. Their biggest problem is their own endurance. There is no way to sleep on this small Jiaolong, but at this time, everyone is in excitement, and they will not sleep at all. Feeling tired.

  Even if it is Kwasha, he, a foreigner, is extremely excited. After all, they always regarded the Americans as their opponents back then, but now, they are fighting against the Americans.

   "Qin, you are simply a genius!" Kwasha was very emotional.

   Only Qin Tao can come up with this kind of plan.

   "Yeah, I also think I'm a genius." Now Qin Tao doesn't have the slightest humility.

There is also a sonar on their deep-diving lifeboat, but this sonar is only used for communication. The synthetic aperture sonar, which specializes in detecting submarine terrain, is still under development and has no equipment. Sonar, so they don't know whether the 403 is safe or not, but judging from the opponent's formation, it should be directed at their side.

   Driven by the Nancang, the deep-submersible lifeboat was advancing at a speed of 16 knots, and the underwater square dance was still playing on the tape recorder at the back, and Xu Zhengyang was also excited.

   "Everyone should go to sleep. We need to carry out an operation like this for a whole day." Qin Tao said.

This day is still not peaceful. There may be fighter planes flying over, or flankers and tomcats. However, they are very calm underwater. They only have one thing to do, which is to rest and replenish their strength. At night, they still have tasks!

   This day has finally passed.

  When night fell on the sea, Qin Tao under the water opened his eyes: "Everyone, the fun is about to begin!"

  Everyone is excited.

   "Attention, release the cable!"

   All the way here, the Jiaolong was dragged by the Nancang. At this time, the single shaft and single propeller of the Nancang showed a high enough advantage: the possibility of the cable being stirred into the propeller was too small.

   After all, the cable is released from the port side, as long as the Jiaolong does not turn right, go straight or turn left, there is no problem.

  If it is a pair of propellers, the propellers are closer to the sides, and there may be accidents under the impact of sea water.

  At this time, the Nancang, which was advancing at high speed, began to turn left, and the Jiaolong, which was freed from the cable, continued to move forward. Just like that, the two began to separate!

  The sonarists burst into excitement: "They broke away, already broke away, we heard two different voices!"

   "That submarine is starting to dive!"

   "It can't escape, send our Los Angeles over there!"

   Various arrangements are in full swing, and a feast of underwater containment kicked off.

  However, after a while, they felt something was wrong.

   "Dive to a depth of 100 meters!"

   "Dive to a depth of 200 meters!"

   "Is it going to escape into the deep sea? Impossible, absolutely impossible!"

  Among their discussions, an astonishing number came: "Three hundred meters!"

  The target dived to a depth of 300 meters!

   "We have never found that this kind of submarine can dive to a depth of 300 meters. It seems that we have pushed it into a hurry."

   Just as they were feeling emotional, even more terrifying numbers kept popping out of the sonar operator's mouth.

   "Three hundred and fifty meters, four hundred meters!"

   "Impossible, this is absolutely impossible. All our data shows that the limit dive depth of this submarine is 300 meters. We have never found it below 300 meters!"

  Although Lao Maozi’s Kilo-class submarines can dive to a depth of 300 meters, this kind of eastern submarine does not have the ability to dive deeper.

  For a submarine, the dive depth is mainly determined by its pressure hull.

  Every time the depth is lowered by ten meters, the pressure will increase by about one atmosphere. At a depth of three hundred meters, it is equivalent to a pressure of thirty atmospheres. This is already a terrible figure.

   Only advanced steel can withstand such pressure, and if you continue to dive, the pressure will be even greater!

   "Could it be that they encountered a low-density area in the sea? These poor guys!" At this time, some people have begun to sigh.

  In the underwater world, there is a very scary phenomenon, which is the low-density area.

  There is a junior high school physics problem, which is called a ship sailing from the river into the sea. Will it sink for a while or float for a while?

  The buoyancy of the ship must be equal to its gravity. The ancient Archimedes principle tells us that the buoyancy is the gravity of the displaced water. This force remains the same, but the volume will change, because the density of sea water and river water are different.

  The sea water is denser, so as long as it has a smaller volume than the river water, it can provide the same benefits. When the ship enters the sea water, the draft will become shallower.

   Another example, why does the Dead Sea allow people to float directly? It is because the Dead Sea has a lot of salt and a high density.

For a ship sailing in seawater, that is, the draft changes. For a submarine completely submerged in seawater, the draft is already full and cannot be changed. If it encounters a low-density area, the buoyancy will decrease instantly, and the gravity will be greater than Without buoyancy, the submarine would sink quickly.

   That's almost fatal.

   "No, it's not a low-density area. They don't dive very fast. If they encounter a low-density area, they will quickly fall into the deep sea!"

   "500 meters, they have dived to 500 meters!" Another amazing voice.

   "Damn, how is this possible, almost reaching the limit of our Los Angeles submarine!"

  The design diving depth of the Los Angeles submarine is 450 meters, but if you are in a hurry, you will not have much problem diving to a depth of 500 meters.

What now? How could this backward underwater tractor in the East dive to such a depth?

   Absolutely impossible!

   "It's still diving!"

  The sonar operator’s voice was full of disbelief: “Damn it, is our sonar broken?”

Of course it's impossible, because they have more than one set of sonars on the surface, in the air, and underwater, and many sonars are listening, and they get almost the same conclusion: the diving depth of the target is far beyond their recognition. Know.

   "Six hundred meters, it has reached six hundred meters! I suspect that it is Lao Maozi's titanium alloy submarine!"

   Only Lao Maozi's titanium alloy submarine has dived to this depth. Could it be that they followed the wrong one?

"No, no, our planes took pictures of it floating, we just came after it, this is the 403 sub, damn, how did they do it? They should be squashed like sardines by now That's right!"

  Underwater, Qin Tao's face was full of excitement: "Guess what those guys are thinking now?"

"They must have thought it was our titanium alloy submarine!" Kwasha said excitedly: "Only our titanium alloy submarine can dive to such a depth, a depth that their torpedoes cannot reach, and they have no means of attack! "

  The Lapis Lazuli Design Bureau originally built titanium alloy submarines, and Kvasha felt very fulfilled at this time: "Shall we dive to a depth of 1,000 meters to scare them?"

   "No, if they dive further, they should really be suspicious. Now, we gradually reduce the volume to create the illusion of leaving, and then return!"

  The underwater sound is slowly getting smaller and smaller.

  The sonarists are still in a daze.

"It can sail freely at a depth of 600 meters, which means that its design depth has reached 600 meters. Damn, what kind of steel is this made of? Even our HY80 steel can't reach this depth !"

   "Yes, only the HY-100 steel that is being developed can make our submarine reach a diving depth of 600 meters. How did the Orientals do it?"

  They were amazed and unwilling. It is obvious that our country's technology is the most advanced. How can it be compared?

  They are not reconciled, but they have no other choice.

   The underwater sound is getting smaller and smaller, and finally disappears.

   "We lost track of it."

   "Damn it, I don't believe it, I don't believe it!"

   I don’t know how many people are cursing the powerful performance of that submarine. They don’t know that they have been fooled.

"In the future, their submarine designers will be busy." Qin Tao said happily: "They found out that our submarine is so powerful, so they can only continue to do research and strive to surpass us. They can't compare, and their designers should find a piece of tofu and kill them."

   "Yeah, they should be busy now, but, Mr. Qin, under our stimulation, will they really make this kind of submarine that dives to a depth of 600 meters?"

"Won't."

   "Boss Qin, why are you so sure?" Xu Hua was a little surprised.

   "Because steel that can meet this performance cannot be manufactured at all. If it can be manufactured, why does Da Mao still make titanium alloy submarines?"

  The Seawolf-class submarine boasted that it could reach a dive depth of 610 meters, but what about the result?

  Decades later, someone finally stood up. Because they failed to meet the design indicators, they were under heavy pressure, so they simply falsified key data!

  A metallurgical expert named Elaine Thomas pleaded guilty. From 1985 to 2017, for more than 30 years, the steel they provided was substandard!

   As a result, the metallurgical experts in the East complained bitterly. The eagle sauce is too much, and it doesn't talk about martial arts! It took me twenty years to reach half of your data, and it took me until I retired to reach 80% of your data. After a long time, you don't have this kind of steel yourself!

  I have been doing 996 all the time, so there is no need for it!

   Now, things should be reversed. Under Qin Tao's stimulation, those guys on the opposite side should suffer! Let them toss, toss and toss, toss and toss, toss for decades, finally, here is the decryption, we were fooling people back then!

   Thinking about how ugly the other party's face was at that time, Qin Tao was so happy at this time.

  In the predetermined sea area, the Jiaolong floated up, waited for more than ten minutes, and was salvaged by the Nancang. This mission was successfully completed!
