Chapter 126 Project 877 Submarine

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

  Air-diving fast is a route that has been taken since the establishment of the Navy. What achievements have been made until now?

Air power needs to rely on the seven masters and eight masters, which is a generation behind developed countries. The speedboat power, that is, the catamaran high-speed missile boat that has just started sea trials and has not yet been formally equipped with troops, looks modern. Submarines Well…

   Submarines are even more behind.

  Although there are nuclear submarines, it only solves the problem of whether they are available or not. The noise of the 091-class nuclear submarine is so loud that the submarines of the US Navy can be heard hundreds of nautical miles away.

  As for conventional submarines, the 035 submarines currently mass-produced are nothing but upgraded products of old Maozi imitations of German submarines of World War II. The speed is slow, the noise is loud, the performance of the equipment is poor, and the power system is backward. Just look at the shape of the bow of the boat to know how far it is from the world's advanced level.

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

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

   "I heard from Comrade Nicholas that you are here to visit the Type 877 submarine. I will take you there and give you a brief introduction." Ardar 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 877-type submarine was built at our Komsomolsk Shipyard, with a construction number of 451. After serving The serial number is B-248, after it was built, it was delivered to the Pacific Fleet and became their training boat to train the seed crew.”

  Nicolas added a sentence on the side: "Yes, I remember this submarine. It is very good, and its quiet performance is quite good. The Americans call our submarine an oceanic black hole."

   "Yes, a lot of noise reduction technologies are used on it. For example, sound-absorbing tiles are laid on the surface of the submarine. Inside the submarine, all the machines are installed on shock-absorbing bases." Aldahl continued.

   At this time, everyone has come to the construction berth of the 877 submarine. At this time, a submarine under construction is laying sound-absorbing tiles on the surface. The propeller at the rear has been covered with a piece of cloth.

Looking at those square sound-absorbing tiles, Qin Tao was also very emotional: "My friend, your sound-absorbing tile technology is quite good, and it is many years ahead of the Americans. If you can improve the quality of the paste so that it does not fall off, it will be even better. .”

  Lao Maozi's military equipment has always been heavy and rough, and the noise of the submarine is very loud, so they are constantly researching noise reduction technology.

  In 1965, they began to formally lay anechoic tiles on the submarine, using styrene-butadiene rubber with a certain acoustic structure, and combining it with floating raft technology, the effect is remarkable. However, this thing loves to drop. You can see the scars on the surface of those submarines on the pier 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 the anechoic tiles were first laid 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." Aldahl immediately explained: "They often exceed the normal diving depth, and sometimes there will be rubbing. If it is used normally , The sound-absorbing tile can have a life span of at least five years."

   Can you blame the backward pasting technology? Originally, it was only allowed to dive 300 meters. Those desperate lunatics operated the submarine to play at a depth of 400 meters. Under the huge water pressure, the sound-absorbing tiles would of course fall off.

   "Really? That shows that your submarine has excellent performance!" Qin Tao said.

"Of course, our submarines all use a double-hull structure, with a reserve buoyancy of 32%, which is half more than the western single-hull structure." Algiers said, "The current submarine, It is the 877E submarine we built for foreign customers, and I can take you to visit it."

Western submarines have only one shell, and the inside is the place for normal life, work and fighting. Lao Maozi’s submarine has two shells, the inside is a pressure-resistant shell, which can withstand the pressure of sea water and carry the crew, etc. The outer shell is in a non-resistant shell. In the pressure shell, a large number of equipment are directly installed outside the pressure shell. After the dive, 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 impact. Even if a torpedo blows up, it may not be able to blow up the pressure hull inside. The survivability is just right.

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

   Moreover, as long as you think about it, you can know that these submarines must be made for Ah San. Thinking of this, Qin Tao is even more emotional.

   In the future, our side will also have advanced diesel-electric submarines, not only for our 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 this submarine is almost ready for delivery, and there will be no fire or poisonous smoke. Everyone went in and checked back and forth, just like Grandma Liu entered. The same as Grand View Garden.

   "My friend, this submarine of yours is really good. It opened our eyes. After we inspect the submarine, we will ask our superiors for instructions. Maybe we will come to negotiate an order soon." Qin Tao said.

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

  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 can be added to make it have greater underwater endurance." Qin Tao said.

"Well, we..." Algiers obviously wants the Ruby Design Bureau to design a Type 636 diesel-electric submarine with 1.5 times the power. However, a technical officer on the side said: "If you want to enhance the water In order to improve the endurance, it is necessary to add air-independent propulsion technology (AIP does not know what it is called in Russian) cabin section. In this regard, our Soviet technology is also very powerful. If you need it, we can add this cabin section. go in."

   This guy is pretty smart, by the way, what's his name? Like Grishin?

  In Qin Tao's memories, some fragments of his previous life appeared. This guy who was not in his eyes at first gradually became clear in his brain.

   This is a nasty guy, tonight, I must pour him out!
