Chapter 406 The Jiaolong Deep Submersible Lifeboat
From the appearance, the Jiaolong looks a bit like a big bomb that has been cut into pieces.

The whole is approximately a cylinder, with the tail shrinking backwards. There are four fins. The upper part of the front is protruding, and the lower part is concave. There are two mechanical arms on both sides. There is a piece of glass in the center of the concave. It is the only observation window of this deep diving lifeboat.

There are searchlights on it, and four small water jet propellers at the tail, which can flexibly change the direction of the nozzle for maneuvering.

The overall length is less than ten meters, and the width and height are about three meters. Such a displacement is on the order of more than 20 tons.

At this time, Kwasha, the designer of this deep-diving lifeboat, was standing in front, explaining to everyone.

"After entering the 80s, the deep diving equipment built by various countries has a similar shape. The French Parrot and the deep diving 6500 of the island country all have this shape. In fact, its appearance is not important because it is a double-hull submarine. Inside it, there are two spherical pressure chambers. The front one is smaller in diameter and can only accommodate three or four people. The rear pressure chamber is larger in diameter and can accommodate more than a dozen dead submarine sailors at one time. .”

The spherical shape is the shape that can withstand the highest pressure. Therefore, no matter what the shape of this deep-diving lifeboat is, the cabin that actually carries people inside is a cabin with a spherical structure, which is the safest.

At this time, listening to Kvasha's introduction, Qin Tao was a little confused: "Since the inner spherical shape is the pressure chamber for carrying personnel, why is our shell also made of titanium alloy?"

The outside is shining with silver light, which is clearly pure titanium alloy!
Since there is no need for the shell to withstand pressure, why use this material?This thing is very expensive!

"Of course it is for lightness and strength. The lighter our deep-diving lifeboat is, the better its maneuverability in the ocean is. You think it needs to be carefully adjusted to dock with the submarine's rescue hatch. If it is too Heavy, too much inertia, it may be difficult to adjust.”

"Doesn't it have a robotic arm?"

The existence of the mechanical arm makes the movement of the submarine very convenient. Just like the excavator, it can get on and off the transport vehicle by itself. It uses the mechanical arm to grab the shell of the submarine and fix itself, which is convenient for fine movement.

"Cough, cough, let's talk about its power system now. It can be divided into two ways. It can sail freely with internal batteries, or it can be powered by a cable like a diving bell, but this method will be very troublesome. , not flexible at all, as for its dive depth, after our repeated calculations, it should be able to dive to [-] meters."

Kwasha actually skipped Qin Tao's question.

why why?
This guy must be hiding something!Qin Tao can already guess what it is.Kwasha also designed the shell as a titanium alloy purely out of his liking for titanium alloys. Anyway, they got a lot of titanium alloys, and it's not a big deal to consume some of them.

In fact, this is a waste. These titanium alloys can be used for many things. No matter how many things there are, they can't be wasted!
Qin Tao's heart was bleeding, but the others didn't care, they were stunned by the depth of what Kwasha said.

Ten thousand meters!

What is this concept?
The French, the islanders, and even Lao Maozi himself seem to be able to dive only to a depth of 6000 meters. I have never heard of a submersible that can dive to a depth of [-] meters!

This is definitely a world record!

"Of course, considering a certain safety margin, there is no problem for this deep-diving lifeboat to dive to a depth of 7000 meters. In this way, our Jiaolong will become the deepest diving boat in the world. deep dive device."

In fact, if a submarine crashes, there is no need to rescue it at this depth. After all, the limit depth of a conventional submarine is 300 meters. was crushed.

Therefore, if it is only for the rescue of submarines, a limit diving depth of 2000 meters is enough.The special submarine deep-diving lifeboat imported by the navy of later generations from the United Kingdom can only go down to 600 meters.

The current Jiaolong is not only used for submarine rescue, but also for scientific research. It has a dual identity.

"7000 meters, I really don't know what's underwater there." Wu Shengli said with emotion: "We can also go down to see it when it is equipped with our navy."

"If the Navy wants this Jiaolong, then they should give us the funds." Qin Tao said, "This deep-submersible lifeboat is not cheap. I think it is worth at least [-] million."

[-] million!

Wu Shengli opened his eyes wide: "Is it so expensive?"

"Two hundred million yuan, not U.S. dollars, is it still expensive?" Qin Tao said, "If we push it to the international market, it should be able to sell for two hundred million U.S. dollars."

Wu Shengli was a little speechless, this kid, did he blackmail the navy?
The previous crises of their Mingzhou Group were all disguised. They are still thriving now. How can they need too much money? Is it necessary to blackmail the navy like this?
"Moreover, this kind of deep-submersible lifeboat can't be operated by itself. It also needs a mother ship, which is another expense. In my opinion, the Navy has to place an order for another [-] million mother ships for us, and finally they will be packaged and sold together."

This kind of deep-submersible lifeboat only has a displacement of tens of tons, so it must have no self-sustaining ability, that is, it can only move underwater for a few hours. If you want it to run around in the sea, it needs to be carried by the mother ship.

This is indeed a supporting package, but it would be too much to ask for another 054 million. How much is a [-]?

"You treat it as a sweet pastry, so use it yourself, we don't need it." Wu Shengli said.

That is what the navy needs. The Mingzhou Group is not a scientific expedition team, nor does it have a submarine force, so it will never want this kind of ship.

Hearing Wu Shengli's words, Qin Tao nodded: "It seems that I can only use it myself. Let's go north first and salvage the wreckage of the Dingyuan ship."

Only then did Wu Shengli realize that Qin Tao felt uncomfortable because of this matter!
When the aircraft carrier park opened last year, Qin Tao said that the wreckage of the Dingyuan ship should be salvaged and a museum of the Dingyuan ship should be built in the aircraft carrier park to educate patriotism.

At that time, Wu Shengli agreed, but he had to wait until the beginning of spring, when the wind and waves were small, before salvage.

The results of it?
The result was forgotten.

There are so many things, how can I remember them? This kind of thing is just a trivial matter. It is estimated that even Qin Tao has forgotten it.

Until now, after seeing this deep-diving lifeboat, Qin Tao suddenly remembered that there is still the matter of salvaging the wreckage of the sunken ship!
So, I started to make a fuss here. My son-in-law, who is capable, will also cause headaches.

"When you salvage, let's send a few divers to cooperate together, can it be okay?" Wu Shengli said: "The salvage of the wreck of the Dingyuan ship can let our people remember the history and has important patriotic educational significance. We will definitely support it with all our strength. "

"Then let's do it quickly. If it's too late, there's a lot of wind and waves on the sea over there, so we won't be able to salvage it. It will take another year."

"Didn't you just say that you need a mother ship?"

"Well, the mother ship is needed, but we can temporarily replace it with other ships, as long as there is a crane."

When he said this, Qin Tao thought of something: "The comprehensive supply ship Nancang is currently undergoing sea trials, so this ship will do."

Nancang number?
The naval officers and soldiers looked different.

The comprehensive supply ship is also Qin Tao's masterpiece. At the beginning, Qin Tao got it from Lao Maozi in a semi-finished state, and ordered a large number of supporting equipment from St. Petersburg, and assembled it in Mingzhou Shipyard.

When it appeared, it immediately became the navy's largest comprehensive supply ship, with a displacement of 2 tons, and it could provide more than [-] tons of supplies!
The work of the Mingzhou Group is not fast. On this warship, they have been working hard. Of course, it is also to attract the attention of others, and they plan to sell the same type of warship.

This large comprehensive supply ship has 4 liquid cargo supply stations, which can carry out horizontal and vertical supply operations, as well as 2 dry cargo supply stations and 6 heavy-duty cranes. Any heavy-duty crane can easily lift hundreds of ships. Tons, this [-] to [-] ton deep-diving lifeboat is naturally also a pediatric.

However, that is a [-]-ton large-scale comprehensive supply ship. Using it as a mother ship for the Jiaolong, isn't that a sledgehammer?How much oil do you need to burn to take things out?
Mr. Qin has a big face, our navy can't afford to burn oil!

"President Qin, can we use other boats?" Someone asked Qin Tao cautiously.

"Other ships?" Qin Tao shook his head: "No, no, the other ships are too small and not stable enough, and it's time for the Nancang to conduct a special long-distance voyage test, so I just took advantage of this opportunity to carry out salvage work , It also saves the navy from disliking the unreliable power system of this supply ship."

Generally speaking, naval ships have at least two oars and two rudders, so that if one side fails, the other can still be used.

Since the Nancang is based on an oil tanker, it uses a single oar and single rudder. The navy is worried that its power is not enough, but there is no other way, and it is finally required.

This time I came on a long-distance voyage, driving from Mingzhou to the northern waters, testing the reliability of the power system, and just reassuring the Navy.

"That's right, a test should be done, then listen to Mr. Qin." Wu Shengli nodded.

The money that should be spent has to be spent, isn't it just a voyage test.

So, things were arranged like this.

Half a month later, Weihai Bay.

"Our superiors attach great importance to our salvage this time, and specially allocated a special sum of money for us." Liu Yong, the captain of the Nancang, looked at Qin Tao who came down from the helicopter platform and said: "And, if necessary, we can also pay for it." Special archaeological experts will be sent to help."

Qin Tao shook his head: "The appropriation is fine, but the experts are fine. What if the experts take a fancy to the wreckage that was caught?"

Of course, Qin Tao knew how important the wreckage of the Dingyuan ship was to those who studied history, and it would be very troublesome if they got entangled.

"However, without the help of experts, we can't determine the specific location. After all, the main body of the Dingyuan ship has been taken away by the islanders. There are not many wrecks we can salvage, and our supply ship has no advanced equipment." sonar equipment. Shall we send divers down there first?"

If the entire Dingyuan ship is below, then of course they can find it easily. The problem is, there are some wrecks left now, how to find them?
Qin Tao smiled: "I have consulted a lot of information and determined the possible locations of the wreckage of the shipwreck. Now, we will look for it from the most likely location. The relevant coordinate data is here. The divers are not needed for the time being. Let the Jiaolong first Go down and try your luck."

Looking at the A4 printing paper handed over by Qin Tao, there were more than a dozen possible locations written on it, all of which were marked with GPS coordinates. He was very curious. Mr. Qin is so amazing that he even knows these?Moreover, he had a hunch that Mr. Qin's coordinate data might be correct!
Nancang has a large displacement and a large ship. Qin Tao walked forward from the helicopter platform, bypassed the bridge, passed through the gantry, and came to a lifting platform on the left side of the front.

The shiny Jiaolong is fixed here, and its surface is sprayed with three large red characters, Jiaolong, which is said to be written by Wu Shengli with a pen, flying like dragons and phoenixes, next to the three characters is a brightly colored national flag .

Apart from these, there is no other painting.

"Although I think it looks better without spray paint, but after all, it has to have the name of the boat. Now, this color match is not bad. You Chinese just like red." Kwasha said.

Qin Tao smiled: "Yes, it needs to be embellished. Kvasha, do you want to go down with us?"

"Yes, as a submarine designer, I have to take a submarine and go down to test it."

Submarines are different from other equipment. In the event of an accident, there may not even be a chance of being rescued.Especially a brand new submarine will face many dangers.

However, submarine designers must go on the submarine. If they dare not go up, what face do they have to ask others to test it?

Even some aircraft designers will fly their own designed aircraft for flight tests, and submarine designers will do their part.

"Okay, then I'll go down with you."

"Boss Qin, you can't go down, it's dangerous there." Xu Zhengyang expressed his opinion immediately.

"The average depth of the water here is tens of meters, and the deepest part is only 70 meters. What danger can there be? Our Jiaolong can dive to 7000 meters. Now, I will only go to a depth of tens of meters." Can't you take a look?"

Xu Zhengyang did not insist.

Generally speaking, if you drop to a depth of ten meters, you will increase the pressure by one atmosphere. At a depth of 70 meters, that is, seven atmospheres, it will not cause any special harm to people. After all, in the world record, a person without any equipment You can dive more than 100 meters with bare hands.

Even if there is any fatal problem with this deep-diving lifeboat, it is impossible for it to leak at a depth of tens of meters, right?Even if it is missed, there are plenty of opportunities to save yourself.

Xu Zhengyang would never agree to go to the Mariana Trench.

"Add me." Another person expressed his opinion.

Xu Hua, the leader of the automation major at Huating University!

The hull structure of Jiaolong was designed by Kvasha, and the power system was jointly developed by Krasnopolsky and Mingzhou Machinery Factory. However, as a deep-diving lifeboat, only these are not enough.

For example, it needs to have the ability of automatic control. It can automatically orientate, determine the depth, determine the height and hover positioning functions in the water. In simple terms, this is like automatic driving. You can drive there!

In seawater, due to the resistance of the water, various operations will be very complicated. If there is no such automatic control equipment, it will definitely be a nightmare for the driver.

And this device was developed by Xu Hua's team.So for this test, he came along with him, and now, he is going down to test his system.

"Okay, then the three of us will go down together."

"Boss Qin, I'm going too." Xu Zhengyang was anxious.

"What are you going to do?" Qin Tao asked back: "The front cockpit is just right for three people, and one more person will be too crowded."

"Then I'll go to the back."

"It doesn't make sense, so what can you do if you go to the back? You just stay here obediently."

Xu Zhengyang's task is to protect Qin Tao, but in the water, there is no one who can threaten Qin Tao, so it is better for him to stay.

Xu Zhengyang bowed his head again, Mr. Qin was right, it seemed really useless for him to go down.

"What kind of treasure are we going to salvage?" Kwasha was a little curious at this time.

"What we salvage is history." Qin Tao's answer is very philosophical.

History, yes, what they salvage is a piece of history!
"Yes, it is the history of humiliation in modern China." Xu Hua said: "In modern times, our motherland has fallen behind, and the country was opened by the ships and guns of foreign powers, and unequal treaties were signed one after another. .”

Speaking of that period of history, every Chinese will clenched their fists.

"At the beginning of the Westernization Movement, we wanted to enrich the country and strengthen the army. It's a pity that it changed in the end. After the Beiyang Navy was wiped out, it completely lost its ability to resist."

"However, we were not defeated. In the following years, countless outstanding sons and daughters emerged on the land of our motherland. They rose bravely and worked hard for national independence and national revitalization. With such a group of people, our motherland will be strong again."

Xu Zhengyang didn't speak. He was moved by this conversation.

That's right, in order to prevent the historical scene of humiliation from recurring, we must have a strong national defense force!We must also remember history, no matter when, we must not forget!
"It's here!" Liu Yong shouted to everyone.

"Okay, let's go down!" Qin Tao was the first to get in, followed by Kwasha and Yang Hua. The staff behind helped close the hatch and checked repeatedly.

The crane hoisted the Jiaolong, slowly left the ship's side, and slowly lowered it to the surface of the sea. Countless people stood on the side of the ship, watching the Jiaolong slowly enter the water.

"I don't know what I can gain from going into the water this time." Everyone started discussing.

"Yeah, we didn't send divers down in advance either."

"There will definitely be something to gain." Xu Zhengyang is very sure: "Now, let's go to the bridge."

Although it is not a professional mother ship, in order to meet the needs of carrying the Jiaolong, this Nancang has undergone some modifications, such as installing an underwater acoustic communication system for communication with the Jiaolong.

Electromagnetic waves cannot be used underwater. This is a special sonar communication device, which is installed on the bow of the ship, where the noise interference is the least.

At this time, the Jiaolong was already sailing underwater.

This is a wonderful world.

Within 200 meters, sunlight can pass through. The sea here is extremely blue, and occasionally you can see sea fish swimming around. The Jiaolong is in the water like a big shark.

"We can save a lot of electricity by not having to turn on the searchlights," Kwasha said.

A small nuclear reactor is unrealistic. This deep-diving lifeboat is equipped with ordinary batteries, which can only last for one or two hours of activity. Therefore, if you can save electricity, you must save as much as possible.

The two heads crowded together in front of the observation window, observing the outside world. For Kwasha, this was actually the first time.

"We have arrived at the target location." Yang Hua remained calm. He looked at various instruments showing that he had arrived at the destination, but where is the target?
Nothing!
"Well, let's look carefully now. We don't have a special magnetic field detector, so we can only use our eyes." Qin Tao said.

After all, this is not for scientific research, and there is no special equipment.

However, Qin Tao can be sure that the goal is here!

10 minutes later.

"In the front, where the fishes swam, there is a bulge! It's like a steel plate is inserted diagonally!" Kevasha pointed to the front and shouted.

"That's right, it's there! We need to use the robotic arm to dig out the silt there!"

Under Qin Tao's command, Yang Hua switched to manual operation. When the mechanical arm poked into the mud, Yang Hua became excited: "It's about half a meter underwater, and it's all hard. The area of ​​this wreckage is very large. Big!"

The large piece of wreckage has long been taken away by the islanders, and now this piece of wreckage is definitely a big piece. When it sees the light of day again, it will shock the entire archaeological world!
The Jiaolong hovered over the wreckage, and the mechanical arm kept digging. Soon, the armor plate revealed its true appearance.

"The length is about three meters, the width is about two and a half meters, and the thickness is more than 30 centimeters. It should be the armor plate of the Dingyuan ship!"

Yang Hua was very excited. He remembered clearly that the shipbuilding agreement of the Qing government mentioned that the Dingyuan ship "purchased the steel-faced iron armor from the Fuerkeng factory and assembled it on the ship with exquisite workmanship. The iron armor on the sides of the fort is 1540 mm below the waterline. (i.e. 5 feet) and only ... 14 inches thick".In conversion, the armor of the Dingyuan ship is about 35 centimeters thick.

It is similar to the iron plate in front of me.

Judging by the weight, it is estimated to be about [-] tons!
"We have to come down again, clean up the mud now, and next time we come down, bring a sling and hang it up directly!"

When the news was sent back to the Nancang, everyone was inconceivably surprised. Over the past few decades, I don’t know how many people tried to find it, but they didn’t find it. The first time they came, the first time the Jiaolong was launched, they found it?

"Our President Qin is the one who creates miracles, and it's nothing to worry about in his hands." Xu Zhengyang was very excited.

It's so rare to see you making a fuss!
"Report, we just received a telegram." At this moment, the telegraph soldier came to report the news with a serious face.
