Chapter 127 613E Submarine

After the collapse of the Soviet Union, Lao Maozi's military industrial enterprises contacted China many times and sold many of their weapons in order to survive. Grishin's figure could be seen in almost every transaction. This stubborn guy is like a stone in the cave, very hard, adheres to principles, forces himself to make concessions, and has won a lot of benefits for Lao Maozi.

This naval officer was actually among 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 compartment.

Nuclear submarines have unlimited endurance underwater. 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 only 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 will be completely consumed in an hour.

In the past, snorkels were very popular. A large pipe stretched out from the submarine's control tower to communicate with the outside. The submarine's entire body was submerged in the water and the diesel engine was running. It was quite good. However, with the improvement of anti-submarine technology, various anti-submarine The sea search radar carried by the helicopter can easily find the submarine's snorkel, so this state is not safe.

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

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

Lao Maozi has also done in-depth research in this aspect. At this time, after Grishen proposed this plan, Algiers on the side also nodded repeatedly: "Yes, we have studied several aspects of air-independent propulsion technology. In the past ten years, we have had both closed-cycle diesel engines and fuel cells. There is a fuel cell experimental boat docked nearby, and I can take everyone to visit."

Grishin frowned and was about to say something else, but Nikolai spoke: "Yes, 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 modifying diesel engines. Since oxygen is needed, just carry an oxygen tank and you can continue to work.

 When the submarine is sailing underwater without a snorkel, the oxygen in the liquid oxygen tank is transported out, mixed with a part of the inert gas, and transported 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 easy to modify and the cost is low. However, the diesel engine of several thousand horsepower used by the submarine consumes a large amount of oxygen when working. Therefore, this method is very inefficient and is among the worst. Unpopular AIP system.

In the 1950s, Lao Maozi built a batch of 615/617 closed-cycle diesel engine submarines 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 directly converts chemical energy present in fuel and oxidant into electrical energy. It does not need to be burned. The fuel and oxidant are sent into the fuel cell separately, and electricity is wonderfully produced.

Because there is no combustion, the exhaust gas emitted is very clean. Especially for hydrogen-oxygen fuel cells, the only by-product generated is water. It can be said to be an absolutely clean energy source. Therefore, after it was invented, it was considered to be the first advanced technology. The fourth generation of power generation technology has gradually expanded from its initial aerospace applications to more fields.

When everyone walked to a corner of the pier, they saw a diesel-electric submarine with an extremely special appearance, standing alone on the pier. There were two large tanks in front and behind the control tower. It looked like Added four tanker trucks with the same fuel tanks.

(Some articles say that these four large tanks are fuel cells, and they also say that Lao Maozi put the large tanks outside for safety reasons. However, what does the Hero of East China think? These four large tanks are hydrogen and oxygen tanks, and fuel cells. Batteries don’t need to be so big.)

In order to accommodate these four large jars, the middle part of the submarine was widened, just like an old woman. Before getting married, she had a curved front and back, with a devilish figure. After getting married, she would soon become a barrel-waisted old woman.

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

Grishen followed everyone and continued: "Because there are many of our secrets up there, you can only look outside and not go up to visit."

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

Qin Tao glanced at him: "Comrade Grishen, you are really serious about stopping us from going up to visit. Are you worried about our safety and 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 won't explode if it's not filled with hydrogen and oxygen. However, if you officially go on a voyage with these devices, it will be like carrying four big bombs that can explode at any time." Qin Tao said: "You put these four east and west outside, probably because you were worried that it would explode, so you separated them from the crew cabin, right?"

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

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

Grishn blushed.

“Some people are just good at bragging. Leaders, I don’t think this submarine is very advanced. Let’s just ignore it.” Qin Tao said to the leaders behind him.

Wu Shengli smiled secretly in his heart, this was the benefit of bringing Qin Tao here. If it were anyone else, he would be embarrassed to talk to Lao Maozi with this attitude, but Qin Tao was different. He made the old Maozi who created obstacles blush.

"Okay, in order to prove the advanced nature of our submarine, you can go up and have a look! But you can only look at it, not touch it." Grishen said with a red face.

“It’s not your woman, why can’t I touch her? Could it be that if I touch her, it will break?” Qin Tao continued to squeeze her.

Zhao Ling covered her mouth secretly. Qin Tao is such a person. Sometimes he is very sincere, sometimes he is very slippery, and sometimes he is very gangster. More importantly, Qin Tao can actually say such a gangster's words so confidently. !

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

This guy is a straight-line person. He does everything strictly and strictly. If he goes on the Internet in later generations, he will be the most likely to be phished.

“Okay, we won’t touch it.” Qin Tao said, “Leaders, let’s go up and take a look at the Soviet Union’s most advanced fuel cell system.”
