Chapter 126 Type 877 Submarine

 The naval officers who came to inspect were also very emotional at this time.

 Air-to-submarine speed is a route that has been pursued since the establishment of the navy. What results have been achieved up to now?

Air power depends on the seven masters, who are a generation behind developed countries. Speedboat power, that is, catamaran high-speed missile boats that have just started sea trials and have not yet been formally equipped with troops, looks fairly modern. Submarines Well…

 As for submarines, they are even more lagging behind.

Although there are nuclear submarines, it only solves the problem of whether or not. The noise of the 091-class nuclear submarines is so loud that U.S. Navy submarines can hear it hundreds of nautical miles away.

As for conventional submarines, the currently mass-produced 035 submarines are just upgraded products of old imitations of German submarines from World War II. The speed is slow, the noise is loud, the equipment performance is poor, and the power system is backward. Just look at the shape of the bow and you will know how far it is from the world's advanced level.

Now, they are going to see the Type 877 submarine, a submarine that is at the world's advanced level and makes them full of expectations.

“Everyone, welcome to the Komsomolsk Shipyard.” Aldar, the director of the shipyard, personally greeted him with several subordinates.

“Comrade Nikolai said that you are here to visit the Type 877 submarine. I will take you there and give you a brief introduction.” Aldar introduced to everyone as he walked.

"In 1974, the Ruby Marine Machinery Design Bureau began to design a new generation of submarines. Six years later, in 1980, the first Type 877 submarine was built at our Komsomolsk Shipyard, with construction number 451. After entering service The number was B-248. After completion, it was delivered to the Pacific Fleet and became their training boat to train seed crews."

Nicholas added on the side: "Yes, I remember this submarine. It is very good. The silent performance is quite good. The Americans call our submarine the Ocean Black Hole."

"Yes, a lot of silent technology is used. For example, silencer tiles are laid on the surface of the submarine, and inside the submarine, all machines are mounted on shock-absorbing bases." Aldar continued.

At this time, everyone has arrived at the construction platform of the 877 submarine. At this time, a submarine under construction is undergoing the work of laying silencer tiles on the surface. The propeller at the rear has been covered with a piece of cloth.

Looking at those square silencer tiles, Qin Tao also sighed with emotion: "My friend, your silencer tile technology is quite good. It is many years ahead of the Americans. It would be better if the quality of the pasting could be improved so that it would not fall off. .”

 Lao Maozi’s military equipment has always been big and heavy. Submarines make a lot of noise, so they are constantly researching noise reduction technology.

In 1965, they began to formally lay down anechoic tiles on submarines. They used styrene-butadiene rubber with a certain acoustic structure, and combined it with floating raft technology, the effect was remarkable. However, this thing is loveable. Just look at the scars that appear on the surface of the submarines at the dock of Lao Maozi's submarine when they are basking in the sun.

As for the Americans, it was much later. It was not until 1988 that anechoic tiles were laid for the first time on the "Los Angeles" class nuclear submarine "San Juan".

"That has nothing to do with the quality of our pasting. It is mainly caused by the brutal operation of the submarine sailors." Aldar immediately explained: "They often exceed the normal diving depth, and sometimes collisions occur. If used normally, , the silencer tiles can have a lifespan of at least five years."

Can we blame the lagging technology for pasting? Originally, it was only allowed to dive to a depth of 300 meters. Those crazy lunatics operated the submarine to a depth of 400 meters. Under the huge water pressure, the silencer tiles would of course fall off.

“Really? That shows that the performance of your submarine is very good!” Qin Tao said.

"Of course, our submarines use a double-hull structure, and the reserve buoyancy is as high as 32%, which is half more than the Western single-hull structure." Algiers said: "Currently, this submarine, It’s the Type 877E submarine we built for foreign customers, I can take you to visit it.”

Western submarines have only one shell, and the inside is the place where normal life, work and combat are. Lao Maozi's submarine has two shells, the inner and outer shells. The inner one is a pressure-resistant shell, which can withstand seawater pressure, carry crew, etc. The outer shell is not resistant to pressure. In the pressure shell, a large amount of equipment is installed directly outside the pressure shell. After diving, the remaining space between the two shells will be filled with seawater.

For large nuclear submarines, the seawater layer is even one or two meters thick. Needless to say, they are not afraid of collisions. Even if the torpedo explodes, it may not be able to destroy the pressure hull inside, so the survivability is just right.

This type of submarine is also exported in large quantities. Type 877E is a specialized export model. The internal sonar equipment and communication equipment have been downgraded. Therefore, we can safely and boldly let everyone step up and visit.

Furthermore, if you think about it carefully, you can know that these submarines must have been made for Ah San. Thinking of this, Qin Tao became even more emotional.

 In the future, our own side will also have advanced diesel-electric submarines, not only for its own use, but also for export! The performance is even better than this 877 and the later improved 636!

If it is a submarine that is being welded, it is dangerous to go in. Now the submarine is almost ready for delivery. There will be no fire or poisonous smoke. Everyone went in to check it back and forth, as if Grandma Liu had entered. Same as Grand View Garden.

“My friend, this submarine of yours is really good. It’s an eye-opener for us. After we, the navy officers, inspect it and ask our superiors for instructions, we may be able to discuss the order soon,” Qin Tao said.

Although Qin Tao can only be regarded as a consultant, because Qin Tao can speak fluent Russian, communicate easily, and is the spokesperson of Wu Shengli, he directly started making promises here.

Algiers nodded: "That's really good news."

 The aviation industry wants to sell aircraft, and their shipbuilding industry wants to sell warships and submarines. These are all good news.

“The weak underwater endurance of diesel-electric submarines is always a problem. It would be great if more batteries could be added to give it greater underwater endurance,” Qin Tao said.

"Well, we..." Algiers obviously wanted the Type 636 diesel-electric submarine that Ruby Design Bureau was designing with a power increase of 1.5 times. However, a technical officer on the side said: "If you want to enhance the water To improve endurance, you need to add air-independent propulsion technology (I don’t know what it’s called in Russian for AIP). In this regard, our Soviet technology is also very powerful. If you need it, we can add this kind of cabin. Get in."

This guy is quite clever. By the way, what is his name? It seems to be Grishen?

 In Qin Tao's memories, some fragments of his past life appeared, and this guy who had not paid attention to him at first gradually became clear in his mind.

This is a nasty guy. Tonight, I must blow his mind!
