Chapter 2774

"President Qin, welcome to our Ruby Design Bureau for inspection." spesky smiled: "our Ruby design bureau is the pride of the whole bear country. Now, we have embarked on a new era. The submarines we design will not only be used by ourselves, but also create a new era of export. Now, please allow me to introduce our 877 submarines."

Qin Guan was even more impressed. There was no nonsense. He directly entered the theme. His own side came here to dig people, but others directly began to sell. With the leadership of such designers, it is no wonder that the ruby Design Bureau will stand up in this tide.

877 submarine is the kilo class submarine. The title of kilo class is the name of this submarine in western countries. Xiong Guo won't call it that. In their project code, it is called 877. All their submarines are named in this three digit numbering scheme.

Now, with spesky's introduction, the design drawings of this submarine are printed on the projector.

"For the conventional diesel electric submarines in the past, we adopted the shape design that is convenient for water navigation, while for this submarine, we adopted the teardrop type overall design like the nuclear submarine, which looks very round in appearance and increases the internal volume. At the same time, the underwater speed is also higher than the water speed." spesky personally introduced it, because, This submarine is his masterpiece. It is his first work after becoming the chief designer here!

It has many innovations. For example, its shape is similar to that of a nuclear submarine. The front horizontal rudder is located at the bow and the tail is strange. There is a pair of horizontal tail rudders and a vertical rudder below, but there is no vertical rudder above.

At the same time, compared with the previous submarines with two axle propulsion, this submarine adopts single axle propulsion for the first time, which can reduce the noise and obtain better mute effect.

Many diesel electric submarines have a displacement of only a few hundred tons, and those with a displacement of more than 1000 tons can be called large submarines. Now their submarine has a floating displacement of about 2300 tons and a submarine displacement of more than 3000 tons, which definitely belongs to the category of large diesel electric submarines. At the same time, it inherits the previous design of Xiong Guo and adopts a double shell structure, which can greatly increase its anti sinking performance.

At present, the largest conventional submarine in China is the supporter class submarine purchased from Baiyin. The underwater displacement is only more than 2000 tons, while the current kilo class has reached more than 3000 tons. You know, some small nuclear submarines are only three or four thousand tons, and medium-sized nuclear submarines are only five or six thousand tons.

The second page is the detailed design of the submarine. You can see the detailed design drawings. Meanwhile, spesky continues to introduce: "The interior of our submarine is divided into six watertight compartments. Looking from front to back, the torpedo compartment is at the front. Starting from the second compartment, it is divided into upper and lower layers. The upper layer is the command room and the lower layer is the battery room; the third compartment is the same. The upper layer is the crew bedroom and kitchen, and the lower layer is the battery room; the whole compartment behind is one layer, which is the diesel generator room and the main propulsion motor room Engine room, standby electric engine room. "

It can be said that the design of the whole submarine is quite reasonable, just like most other diesel electric submarines, but it looks clear and clear. Arms dealers like Boris also nod frequently. Although he has not sold diesel electric submarines, he also knows that such submarines are very famous in the world. A few years ago, he also exported a batch of them to the white elephant country.

"Mr. Qin, are you interested in our submarine?" after introducing various mute technologies, spesky said to Qin Guan.

President Qin, what are you doing here? No matter what he does, if you want him to come, you have to have 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 problem that can not be avoided."

"Yes, its underwater cruising power can't be compared with that of a nuclear submarine." smart people don't have to talk nonsense and can get to the point at once.

Nuclear submarines, relying on the nuclear power system, have almost unlimited cruising power, which is just the physical limit borne by submarine personnel. Diesel electric submarines are different. No matter how many batteries are installed in them, they are used up. Therefore, most of the navigation states are through the air pipe.

Many helicopter antisubmarine radars search for ventilation pipes. When they find them, they will attack, which is the biggest disadvantage of conventional diesel electric submarines.

However, it is absolutely impossible for it to have long endurance. It is also for this reason that the eagle country has eliminated conventional submarines, and underwater forces are all nuclear submarines.

Qin Guan nodded: "of course, it can't be compared with a nuclear submarine, but as long as we find a way, we can still greatly improve its underwater endurance, even if it is increased to more than a week, that's good."

"Mr. Qin, do you mean AIP System?" spesky asked Qin Guan.

Qin Guan nodded: "yes, if this submarine can be equipped with AIP System, we have the intention of purchasing. We can buy four in the first batch."

As like as two peas, the conventional power submarines are divided into two working states, which are powered by diesel engines and charged by batteries when they are sailing on the surface or in the condition of vent pipes. Batteries are used to power the battery while they are underwater. The batteries are the same as the batteries for old scooters. They are lead-acid batteries, so they do not store much energy. Often start the diesel engine to provide power, which is not conducive to concealment.

How to make the submarine increase more underwater navigation time has always been the pursuit of submarine designers. This is the emergence of AIP System. The term means a power plant that does not rely on air.

After hearing Qin Guan's words, speskitton frowned. This phenomenon has never existed in the previous exports of bear country. What they export is what they export, and they will never be modified according to the opinions of buyers. Even if they are exported to tropical countries, their tanks will not be equipped with air conditioning and heating system used in cold places. Do you like it or not.

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

In particular, President Qin has always done what he said. Four conventional powered submarines will benefit their ruby Design Bureau and corresponding shipyards! You must get this order.

But, AIP System, what you say is light. Is it easy?
