Chapter 2325: Advanced design

No one would doubt Qin's design, and everyone knows that the relationship between Han and Xiong is now good, and Qin is able to find more information about Xiong and even experts.
Apart from other things, President Qin even got Xiong Guo's missile production line. What else could President Qin fail to do? The design of this submarine looks full of the characteristics of the bear country.
Yes, the drop shape is the best, but the drop shape has insufficient internal space. Therefore, the general submarine uses an elongated drop shape. The aspect ratio of this submarine is 8.2:1, which is already very good. The design is close to seven to one.
"Look again, everyone, the bow is round and blunt, the front is thick and the back is thin. This design allows a larger sonar system to be placed in the front, with better underwater monitoring performance, and at the same time, it also reduces the wet surface area of ​​the hull. And the resistance of the hull. Of course, in pursuit of the ultimate in appearance, the flat deck was cancelled, even if it is on it, it is in the form of an arc." Qin Guan pointed to these places and then introduced.
At the very beginning, submarines mainly sailed on the surface and only dived during combat. Therefore, the shape of the submarine was the same as that of a surface ship. In this way, until nuclear-powered submarines, the underwater navigation time was greatly increased, and even all of them were underwater. Sailing, this changed the shape of the hull, but when it comes to canceling the flat deck, it is still a bit suspicious.
"Then what should a sailor do if he wants to work on deck?" someone asked.
"Special shoes on board." Qin Guan said: "Moreover, nuclear submarines, from sailing to your trip, almost all operate underwater, rarely float to the surface, Captain Xu, is that true?"
Others don't know, but Captain Xu knows that their 099-class submarines are really all underwater from departure to return. Therefore, there is really no need for the existence of this deck.
"The front section of the hull is elliptical and reaches the maximum at this position. Then the outer contour line of the hull shrinks towards the center line of the submarine, and smoothly transitions to the tapered stern. It looks like the whole shape is very smooth, in order to prevent It was smashed, and the bow rudder was set on the front of the hull, which can be retracted. Then, let's look at the control tower."
The command tower of the submarine is the highest place of the submarine and also the place with the greatest technological content. Here, there are various advanced electronic equipment. The captain of the submarine is also here to direct the submarine operations. It can be said that this is the core of the submarine.
At the same time, the design of the command tower of this submarine is also quite smooth, which perfectly reduces the underwater resistance and integrates with the hull. This design has been developed from the initial V-class nuclear submarine to the A-class and 971 The model has been further carried forward. In fact, even the submarines of the Eagle Nation's later generations plan to adopt this similarly shaped podium enclosure. A good weapon must be beautiful, and this is also true in the design of the submarine.
The entire outer surface of the submarine is quite smooth, without any holes. Now, after introducing the outer design, everyone has listened 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 reactors are the most mature choice. In order for our submarine to reach a maximum speed of 30 knots or more, the nuclear reactor it is equipped with requires at least 200 megawatts of power. In the state of power, there is no need to turn on the circulating water pump, and it runs entirely by thermal expansion and contraction."
"President Qin, we may not be able to reach this point." The person in charge of nuclear power system research and development said: "Our nuclear power system cannot achieve this power, nor can it achieve its self-circulation capability."
"Regarding the design of nuclear reaction, I also have corresponding information here. After I get down, I will give it to comrades to study." Qin Guan said.
The design of the nuclear reactor is top-secret, and a small parameter difference may bring about a big difference in performance, and in Qin Guan, since all the information is obtained, of course it must be completed.
Hearing Qin Guan's words, the person in charge suddenly became 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 a land-based nuclear power plant. It needs to be small in size, high in power, high in density, and safe and reliable. The domestic research and development experience is not rich. If there is a foreign system as a reference, an experimental reactor is built on land. It can definitely catch up with the submarine's manufacturing cycle.
"What's the tail?" someone asked.
This submarine has a beautiful appearance. Above the rear rudder, there is a cone-shaped thing. The tip of this cone is backward. When it sails on the surface, this thing will be exposed to the sea and look quite The alternative.
what is this? It's actually very simple, drag the body sonar.
The towed body sonar can detect tiny sounds at a long distance and is an excellent underwater equipment. However, because the tail of the submarine is a propeller, it is easy to cause the towed body sonar and the propeller to be entangled. Therefore, in the 971 submarine , I installed this thing on the top of the high rudder so that it can avoid the propeller at the tail.
It has been a matter of recent years that one's own towed body sonar is equipped. There is no such thing on the 091 submarine, and when the surface ship is released, it will not be entangled with the propeller, so everyone is not clear about this.
Now, with a simple explanation from Qin Guan, everyone will understand that if it were not for this detailed design drawing, then everyone would not have guessed at all. Many difficult problems can be overcome with the simplest method.
This big picture also drew the internal structure very clearly. After Qin Guan finished the introduction, a group of experts came up, lay on the design drawing, and studied it carefully.
"President Qin, your design is quite advanced. It will take time for us to digest and absorb this design. We will build it ourselves and it will take time. During this time, our naval submarine force still has a blank period. Ah." The navy commander said to Qin Guan.
Qin Guan smiled: "Please don't worry, we will have it in the next few days. Starting from this evening, please temporarily martial law here. People who are irrelevant, please don't come in."
Originally, the exchange needed to wait for the quality, but here, the next 091 submarine has not been built, but the materials are already prepared here, which gives Qin Guan a good opportunity to use these materials. First exchanged a 971 submarine!
