Chapter 127 613E Submarine

After the collapse of the Soviet Union, Lao Maozi’s military enterprises contacted China many times in order to survive, and sold many of their weapons. In almost every transaction, Grishin can be seen, This stubborn guy is like a rock in a cave, very hard, sticks to principles, forces his side to make concessions, and wins a lot of benefits for the old Maozi.

   This naval officer actually followed the reception staff this time, causing trouble for Qin Tao and the others.

  Originally everyone's topic naturally shifted to the Type 636 submarine, but now, the other party actually talked about the AIP cabin.

Nuclear submarines have unlimited endurance underwater, and how long they can run depends entirely on the endurance of the crew, but diesel-electric submarines are different. Although a large number of lead-acid batteries are installed on them, they can run underwater for a few days It's just time, even if the captain has no choice but to let the submarine sail at full speed, the battery can be completely exhausted in an hour.

In the past, the snorkel was very popular. The conning tower of the submarine protruded a large pipe to communicate with the outside. The submarine hull was completely submerged in the water. The sea search radar carried by the helicopter can easily find the snorkel of the submarine, so this state is not safe.

  The Americans are the most direct, eliminating all conventional diesel-electric submarines, and all nuclear submarines in the navy. Other countries do not have such a luxury, so they have to find their own way.

   It would be great if there is a power system that can sail underwater for a long time.

The old man has also done in-depth research on this aspect. At this time, after Grishin proposed this plan, Algiers on the side nodded again and again: "Yes, we have studied several times in terms of independent air propulsion technology. For ten years, it has two types of closed-cycle diesel engine and fuel cell, and there is an experimental boat of fuel cell, which is docked nearby, and I can show you around."

  Grishin frowned, and wanted to say something else, but Nicholas said there: "That's right, we are all good friends, and we can show you some confidential experimental submarines."

  Diesel engines cannot be used underwater because they need oxygen. Therefore, the earliest AIP system was aimed at transforming diesel engines. Since oxygen is needed, carry an oxygen tank to continue working.

  When the submarine is sailing underwater without a snorkel, the oxygen in the liquid oxygen tank is delivered, then mixed with a part of the inert gas, and delivered to the diesel engine to maintain the normal operation of the diesel engine.

This method directly uses the original diesel engine of the submarine, so it is difficult to change and the cost is low. However, the thousands of horsepower diesel engine used by the submarine needs to consume a lot of oxygen during work, so the efficiency of this method is very low. Unpopular AIP system.

Lao Maozi built a batch of 615/617 closed-cycle diesel submarines in the 1950s, and then gave up. After that, they improved the fuel cell system on one of their 613 submarines. This special submarine , was specially taken out and named 613E.

  Fuel cell is a power generation device that converts chemical energy in fuel and oxidant directly into electrical energy. It doesn't need to be burned, the fuel and oxidant are fed separately to the fuel cell, and electricity is magically produced.

Because there is no combustion, the exhaust gas is very clean, especially the hydrogen-oxygen fuel cell, the only by-product generated is water, which can be described as an absolutely clean energy source, so after it was invented, it was considered to be the first advanced The fourth generation of power generation technology has gradually expanded to more fields from the initial aerospace application to the present.

When everyone walked to a corner of the pier, they saw a very special diesel-electric submarine standing alone on the pier. There were two large tanks at the front and back of the conning tower, which looked like Added four oil tankers like the oil tank.

(Some articles said that these four big tanks are fuel cells, and that Lao Maozi put the big tanks outside for safety, but how does Huadong Zhixiong think that these four big tanks are hydrogen and oxygen tanks, fuel Batteries simply don't need to be that big.)

  In order to accommodate these four large tanks, the middle part of the submarine has been widened, just like an old woman. Before marriage, she had a protruding front and back, with a devil figure. After marriage, she will soon become an old lady with a bucket waist.

"Everyone, what you are seeing now is the latest secret of our Soviet Union." Algiers said: "This 613E submarine was refitted in 1986 to conduct fuel cell testing. The technology it verified, Will be used on our next submarine. You are the first foreigner to see this technology."

  Grishin followed the crowd and continued: "Because there are many secrets about us, you can only look outside, not go up to visit."

   This guy is really annoying enough, Nicholas agreed, but he, a low-level technical officer, wants to stop him here!

  Qin Tao cast a glance at him: "Comrade Grishin, you really have the heart to prevent us from going up to visit. Are you worried about our safety, afraid that the thing will explode at any time?"

  Grishin shook his head: "Of course not, our Soviet technology is the most advanced, how could it explode?"

"That's right, it's not filled with hydrogen and oxygen, so it won't explode. However, if you take these devices with you on a formal voyage, it's like bringing four big bombs that will explode at any time." Qin Tao said: "You put these four things outside, probably because you are worried that they will explode, so they are separated from the crew compartment, right?"

   "Of course not." Grishin shook his head again and again: "Our Soviet technology is the most advanced."

   "Advanced? How advanced? It is placed directly outside to increase the resistance of underwater navigation. This is really advanced!" Qin Tao continued to tease.

   Grishin blushed.

   "Some people just know how to brag. Leaders, I don't think this submarine is advanced. Let's not look at it." Qin Tao said to the leaders behind him.

  Wu Shengli smiled secretly in his heart, this is the benefit of bringing Qin Tao here. If it was someone else, they would be ashamed to talk to Lao Maozi with this attitude, but Qin Tao was different, he ran the old Maozi who made obstacles so red in the face.

   "Okay, in order to prove how advanced our submarine is, you can go up and take a look! But you can only look at it, not touch it." Grishin said with a blushing face.

   "It's not your woman, why can't you touch it? Could it be broken if you touch it?" Qin Tao continued to run.

Zhao Ling secretly covered her mouth, Qin Tao is such a person, sometimes very sincere, sometimes very slippery, sometimes very rascal, and more importantly, Qin Tao is able to speak such rascally words so confidently !

  Grishin gritted his teeth: "If you can't touch it, you can't touch it. It is more precious than my woman!"

   This guy is a straight-line person. He does everything with a straight line. If he goes to the Internet of later generations, he is the type that is most likely to be phished.

   "Okay, we won't touch it." Qin Tao said: "Leaders, now, let's go up and see the most advanced fuel cell system in the Soviet Union."
