Super Weapon Swap System

No one will doubt President Qin's design. Moreover, as we all know, the relationship between Han and Xiong is good, and President Qin can find more information about Xiong, even experts.

Besides, President Qin even got Xiong Guo's missile production line. What else can't president Qin do? The design of this submarine looks full of bear country characteristics.

Yes, the water drop shape is the best. However, the internal space of the water drop shape is not enough. Therefore, the general submarines use the elongated water drop shape. At present, the length width ratio of this submarine is 8.2:1, which is very close to the design of 7:1.

"Look again, the bow is round and blunt, the front is thick and the back is thin. This design can let the sonar system with a larger area be laid down in front, which has better underwater monitoring performance. At the same time, it also reduces the wet surface area and hull resistance. Of course, in order to pursue this extreme shape, the plane deck has been cancelled, even on it, it is in the form of arc." Qin Guan pointed to these places and then introduced them.

At the beginning, submarines mainly sailed on the surface and only went down when fighting. Therefore, the shape of submarines is the same as that of surface ships. In this way, until nuclear powered submarines, the underwater navigation time is greatly increased, and even all of them sail underwater, which changes the shape of the boat. However, when it comes to canceling the plane deck, people still have some doubts.

"What should sailors do if they want to work on deck?" someone asked.

"Special shoes on board." Qin Guan said, "moreover, nuclear submarines, from sailing to your bank, almost all work underwater, and rarely float to the surface. Captain Xu, is that right?"

Others don't know, but Captain Xu knows that all their 099 submarines are underwater from departure to return. Therefore, there is really no need for the existence of this deck.

"The front section of the hull is oval and reaches the maximum at this position. Then, the outer contour line of the hull shrinks to the submarine center line and smoothly transitions to the sharp stern. In this way, it seems that the whole shape is very smooth. In order to prevent being damaged, the bow horizontal rudder is set in the front of the hull and can be shrunk. Then, let's look at the command tower."

The command tower of the submarine is the highest place of the submarine and the place with the largest scientific and technological content. Here, it has all kinds of advanced electronic equipment. The captain of the submarine is also here to command submarine operations. It can be said that this is the core of the submarine.

At the same time, the design of the submarine's command tower is also quite smooth, which perfectly reduces the underwater resistance and integrates with the boat body. This design has been developed from the initial class V nuclear submarine to class A and 971. In fact, even the submarines of later generations of Eagle Kingdom intend to adopt this command platform enclosure with similar shape, Good weapons must be beautiful, as is the design of submarines.

The whole outer surface of the submarine is quite smooth without leaving any holes. Now, after introducing the design, everyone is listening very seriously, because the advanced nature of its design is beyond doubt.

At the end of the introduction, Qin Guan briefly talked about its power system.

"For nuclear submarines, pressurized water reactor is the most mature choice. In order to make it reach a maximum speed of more than 30 knots, the nuclear reactor equipped with it also needs a power of at least 200 MW. Moreover, in the state of low power, it does not need to turn on the circulating water pump and operates completely by thermal expansion and cold contraction."

"Mr. Qin, it's estimated that we can't achieve this." the person in charge of the research and development of the nuclear power system said: "our nuclear power system can't achieve such power and its self circulation ability."

"I also have relevant information about the design of nuclear reaction. When I come down, I will give it to my comrades for research," Qin Guan said.

The design of the nuclear reactor is top secret. The difference of a small parameter may lead to great differences in performance. Since Qin Guan has got all the data here, of course he has to get it all.

Hearing Qin Guan's words, the person in charge was excited. They had long wanted to develop advanced nuclear reactors, but they had no technology, so they had to explore by themselves, and the progress was very slow.

This is different from the reactor of nuclear power plant on land. It needs small volume, high power, high density, safety and reliability. Domestic R & D experience is not rich. If there is a foreign system as a reference and an experimental reactor is built on land, it can definitely catch up with the manufacturing cycle of submarine.

"What's the tail?" someone asked.

The submarine has a beautiful shape. Above the rear rudder, there is a conical thing. The tip of the cone is backward. When it sails on the water, this thing will emerge from the sea and look quite different.

What's this? It's actually very simple. Towed sonar.

Towed sonar can detect small sound from a long distance. It is an excellent underwater equipment. However, since the tail of the submarine is a propeller, it is easy to entangle the towed sonar and propeller. Therefore, on the 971 submarine, this thing is installed on the top of the high tail rudder, so it can avoid the propeller at the tail.

It has been a matter of recent years that our own side is equipped with towed sonar. There is no class 091 submarine at all, and the propeller will not be entangled when the surface ship is released, so we don't know this at all.

Now, as soon as Qin Guan made a simple explanation, we would understand that if there were not this detailed design drawing, we would not have guessed that many difficult problems can be overcome by the simplest way.

The internal structure of this large drawing is also very clear. After Qin Guan introduced it, a group of experts came up and lay down on the design drawing and studied it carefully.

"Mr. Qin, your design is quite advanced. It takes time for us to digest and absorb this design. It also takes time for us to build it ourselves. During this time, our navy submarine force still has a blank period." the naval commander said to Qin Guan.

Qin Guan smiled: "please don't worry. We'll have it in the last day or two. From tonight on, please temporarily impose martial law here. Irrelevant people, please don't come in."

Originally, the exchange required quality, but here, the next 091 submarine has not been built, but those materials have been prepared here, which gives Qin Guanxi a good opportunity to exchange these materials for a 971 submarine first!
