Super Weapon Exchange System

"President Qin, welcome to our Ruby Design Bureau for inspection." Spasky’s face was smiling: "Our Ruby Design Bureau is the pride of the entire bear country. Now, we have embarked on a new era. The submarine will not only be used for its own use, but will also create a new era of export. Now, please allow me to introduce our Type 877 submarine."

Qin Guan is even more admired. There is no nonsense, and he goes directly to the theme. He came here to dig people, but people directly started selling. With the leadership of such a designer, it is no wonder that the Ruby Design Bureau will stand up in this tide. come.

The Type 877 submarine is the Kilo-class submarine. This is the title of the Kilo-class submarine. That is the name of this submarine in Western countries. The bear country will not call it that way. In their project code, this is called the 877 type. , All of their submarines use this three-digit numbering scheme.

Now, with the introduction of Spassky, the design drawings of this submarine are printed on the projector.

"The previous conventional diesel-electric submarines were designed to facilitate navigation on the water. For this submarine, we adopted the same teardrop-shaped overall design as the nuclear submarine. This way, the appearance is very round and the interior is increased. At the same time, the underwater speed is also higher than the water speed.” Spasky personally introduced, because this submarine is his proud work, and it is his first model after becoming the chief designer here. s work!

It has many innovations. For example, the shape is similar to that of a nuclear submarine. The front horizontal rudder is located on the bow and the tail is even more peculiar. It has a pair of horizontal rudders and a vertical rudder below, but no vertical rudder surface above.

At the same time, compared with previous submarines that use dual-axis propulsion, this submarine uses single-axis propulsion for the first time, which can reduce noise and achieve better mute effects.

Many diesel-electric submarines have a displacement of only a few hundred tons. Those over 1,000 tons can be called large submarines. Now their submarine has a buoyancy displacement of about 2,300 tons and a submarine displacement of more than 3,000 tons. It is definitely a large submarine. The category of diesel-electric submarine, at the same time, inherited Xiong’s previous design and adopted a double-hull structure, which can greatly increase its sinking resistance.

The largest conventional submarine in Han China is the supporter-class submarine purchased from Baiyin Country. The underwater displacement is only more than 2,000 tons, while the current Kilo-class has reached an anti-sky displacement of more than 3,000 tons. You know, some small nuclear submarines are only three to four thousand tons, and medium-sized nuclear submarines are only five to six thousand tons.

The second page is the detailed design of the submarine. You can see the detailed design drawings. At the same time, Spasky continues to introduce: "Our submarine is divided into six watertight compartments. We look from front to back. The front is the torpedo compartment. The second compartment is divided into upper and lower levels. The upper level is the command room and the lower level is the battery room. Similarly, the third compartment is the crew’s dormitory and galley, and the lower level is the battery room. It is the first floor, which is the diesel generator room, the main propulsion motor room, and the backup motor room."

It can be said that the design of the entire submarine is quite reasonable, just like most other diesel-electric submarines, but it looks clearly organized and distinct. Arms dealers like Boris also nod frequently, although he has never reselled diesel and electricity. Submarines, I also know that this kind of submarine is very famous in the world. A few years ago, a batch of them were exported to the White Elephant country.

"Mr Qin, are you interested in our submarine?" After introducing the various mute technologies, Spasky said to Qin Guan.

What is President Qin doing here? No matter what he does, let him come, and there must be an order!

"The overall performance of this submarine is good." Qin Guan said: "However, as long as it is a diesel-electric submarine, there is an important issue that cannot be avoided."

"Yes, in terms of its underwater cruising power, it can't be compared with a nuclear submarine." Smart people can speak without nonsense, and they can get to the point at once.

Nuclear submarine, relying on nuclear power system, has almost unlimited cruising power. It is only the physical limit of submarine personnel. Diesel-electric submarine is different. No matter how many batteries are installed in it, it will be used up. Therefore, most of the In the state of navigation, it is all snorkel navigation.

Many helicopter anti-submarine radars search for snorkels. Once they are found, they will launch an attack. This is the biggest drawback of conventional diesel-electric submarines.

However, it is absolutely impossible for it to have long endurance. For this reason, Eagle Country eliminated conventional submarines. Underwater power is all nuclear submarines.

Qin nodded his opinion: "Of course it can't be compared with a nuclear submarine, but as long as we think of a way, we can still greatly improve its underwater endurance, even if it is increased to more than one week, that is not bad."

"Mr Qin, do you mean the AIP system?" Spasky asked Qin Guan.

Qin nodded his opinion: "Yes, if this type of submarine can be equipped with an AIP system, then we have the intention to purchase, and we can purchase four in the first batch."

The current conventional power submarine is divided into two working states. When navigating on the surface or in a snorkel state, it uses a diesel engine as power while charging the battery; when navigating underwater, it uses a battery to provide power. The battery here is exactly the same as the battery of the old scooter. They are all lead-acid batteries. Therefore, it does not store much energy. In this way, the submarine must often start the diesel engine to provide power, which is not conducive to concealment.

How to add more underwater navigation time to submarines has always been the pursuit of submarine designers. This is where the AIP system appears. The term means a power plant that does not rely on air.

Hearing Qin Guan’s words, Spassky frowned. There has never been such a phenomenon in Xiong Country’s previous exports. They export what they export, and they will never modify it because of the buyer’s opinions. Even if they are exported to tropical countries, their tanks will not be equipped with air conditioning, and will be equipped with a heating system for use in cold regions.

But now it's different. They don't have that powerful country anymore. They have to sell equipment on their own. Now, if they want to sell their submarines, they have to satisfy users.

In particular, President Qin has always done what he said. The four conventionally-powered submarines will give them the Ruby Design Bureau and the corresponding shipyards. This order must be received.

However, the AIP system, you said, is light and handy. Is it easy?
