Chapter 533 There is no harm without comparison

Chaudhary walked into the indoor exhibition hall of naval equipment.

Of course Asan's senior naval officers will not come to the East to participate in this kind of defense exhibition. Doing so will only gain face from the East and destroy their own prestige. However, they are looking forward to this time very much, so, Some of their informants were sent.

Chaudhary is Sunil's man. At this time, he is wearing a suit and leather shoes, looking like a reporter. The card on his chest also has the name of Asan Times written on it.

At this time, he was still holding a camera with a telephoto lens in his hand, taking random pictures of things he was interested in.

The big sign of Neva Design Bureau quickly attracted his attention. There were not many people there, so he could easily stand in front of the booth and look at a large-scale design drawing on the other side's booth.

 One month is too short, and most units have no time to make corresponding models, so they can only take out their own design drawings.

The design drawings of the Neva Design Bureau are also large enough. They are placed on a drawing board two meters wide and one meter high. On it is the flagship work of their design bureau: the 1143E nuclear-powered aircraft carrier.

"This is a nuclear-powered aircraft carrier with a displacement of 90,000 tons that we designed. It demonstrates the most powerful warship design capabilities of our Neva Design Bureau." Shaoyigu, a young designer of the design bureau, looked at the people coming over, especially Asan. The reporter from the Times was very enthusiastic and immediately began to introduce him in fluent English.

 Nuclear-powered aircraft carrier, 90,000 tons?

 Hearing these introductions, Choudary knew that the design of this aircraft carrier was not suitable for the Asan Navy.

 For the Asan Navy, it is simply impossible to operate a warship with such a large displacement. The greater the displacement, the higher the cost of construction and the more expensive the use cost!

However, facing the enthusiastic Shoigu, of course he had to be patient and listen.

"This aircraft carrier is fully 350 meters long. It has a jump deck in front of it. It can use ski jump to take off and dispatch the Su-33 carrier-based aircraft on it. There are also two catapults on its angled deck. It can eject and launch carrier-based early warning aircraft and other aircraft. Its comprehensive combat capabilities are comparable to those of the American Nimitz-class aircraft carriers. The total number of aircraft it carries will exceed ninety."

 In the world, only China can keep pace with the United States and design similar aircraft carriers. Other countries simply do not have this kind of strength.

In fact, this aircraft carrier is only slightly modified from the previous nuclear-powered aircraft carrier. In order to attract attention, they enlarged the displacement of the aircraft carrier to 90,000 tons, and the anti-ship missiles that were characteristic of the Lao Maozi era were also removed. It has become the same as the Western aircraft carrier, which is just a platform for carrying fighter jets.

  No matter what, this decent design can still attract some people’s attention.

Chaudhari looked at the design and took a few photos.

“If you are interested, you can do a special report, and we are willing to accept interviews and questions.” Shoigu continued.

“Excuse me, do you only have such an aircraft carrier design?” Shaoyigu asked.

“Of course not, come here, we also have a universal maritime combat complex.” Shoigu introduced.

 Universal maritime combat complex? What the **** is this? At this time, Choudary felt that his mind was getting confused.

 I really don’t know what the **** this is.

“Come here and take a look.” Shaoyigu led Choudary around half a circle to the other side of the booth, where he saw another distinctive aircraft carrier.

　　When he saw this design drawing, Choudary's eyes widened. It looked pretty good!

Chaudhary took several photos by pressing the shutter button wildly.

Shaoyigu was very satisfied: "The design of our 1143F adopts the commonly used method. Two catapults are arranged on the bow of the ship, which can eject and take off various carrier-based aircraft. There is also an angled deck for aircraft landing. It has a displacement of 45,000 tons, is a medium-sized aircraft carrier, and can operate MiG-29K carrier-based aircraft."

 This aircraft carrier is pretty good for our own side! Chaudhary's heart was filled with anticipation.

“But why did you name it a universal maritime combat complex instead of an aircraft carrier?” Choudary asked curiously.

"Look at the back, there is a special dock at the tail of this warship. It is not only an aircraft carrier, but also an amphibious assault ship. When needed, it can also carry a large amount of amphibious equipment for carrying out operations. Cross-sea landing operations.”

It is a complex, not just an aircraft carrier, but also an amphibious assault ship. Isn’t this design too weird?

“Our Asan Times will issue a special report on this aircraft carrier.” Choudary said: “Do you have any other information?”

Generally speaking, those who come to a defense exhibition will not only have the things on the booth, but also have beautifully printed promotional brochures. As long as they have the brochures, they can compile news reports.

Shaoyigu had a ashamed smile on his face: "Sorry, we don't have this kind of information yet."

No?

They came here in a hurry. They didn’t prepare anything, and of course they didn’t have any special information. At this time, Choudary was speechless after hearing Shoigu’s introduction. Is this your first time to participate in an international defense exhibition?

For the Neva Design Bureau, this is really the first time. It is good that they can draw large-scale design drawings. There are no models and no promotional materials. It is as hasty as possible.

“However, if you have any questions, you can ask us at any time.” Shoigu replied.

Chaudhary thought for a while: "Excuse me, do you have the technology to build a catapult?"

"Of course. If the Red Empire had not collapsed, our Ulyanovsk would have been equipped with a specialized steam catapult. In this regard, we still have technical reserves."

“So, what kind of power does this 1143F use?”

"Considering that the boiler is unsafe, our aircraft carrier plans to use gas turbines. Our domestic relevant institutions are currently conducting research. You can go to the Saturn Consortium booth next door to take a look. They have relevant plans." Shaoyigu introduced Very thoughtful.

"Gas turbines are good, but we want to know how gas turbine-powered aircraft carriers use to burn boilers and provide energy for steam catapults?" Choudary's words immediately left Shaoyigu speechless. .

 That’s right, why wasn’t this issue taken into consideration when it was originally designed?

 Without a boiler, how can one boil water? Without steam, how can one provide energy for a catapult?

Because seven of the eight boilers of the Super Sun King exploded during the sea trial, their Neva Design Bureau decided to switch to gas turbines in order to satisfy potential customers. It happened that the Saturn Consortium was developing related gas turbines, and they hit it off.

Their design was hasty and they forgot about these problems. Who would have thought that they would be pointed out to the point by the other party.

 This is embarrassing, what should I do?

At this moment, Sokolov came over: "What's going on?"

Shoigu quickly spoke out the other party's question in Russian. Sokolov thought for a moment and immediately answered: "Tell him that we use the exhaust gas of the gas turbine to burn the boiler!"

Shaoyigu’s eyes were full of admiration. The chief designer is so awesome! Although no one has considered this issue, the chief designer can easily find excuses!

The temperature discharged from the gas turbine is also very high. In order to avoid being tracked by thermal radiation missiles, the warship's exhaust duct must be heat-dissipated, either by opening heat dissipation holes or directly using sea water to dissipate heat. All this heat is actually wasted.

 Now, the aircraft carrier in front of us has been improved and the exhaust gas from the gas turbine has been reused. This solves the problem perfectly, what an idea.

However, for some reason, he always felt that this design was weird.

“Excuse me, why is the island of this aircraft carrier designed so far forward?”

On large aircraft carriers, the take-off area and landing area for carrier-based aircraft are far apart. In order to accommodate take-off and landing, elevators are often located at the front and rear of the ship. In this way, the ship island is placed in the center, with elevators at the front and rear.

However, medium-sized aircraft carriers do not have this advantage. Take the Charles de Gaulle as an example. There is a certain intersection between the take-off area and the landing area, so two elevators are required to be close to the landing area and take-off area respectively to facilitate operations. The parking area between the two elevators is more convenient for scheduling. Therefore, the design of the Charles de Gaulle is very unusual: the elevator is in the middle and rear, and a parking area is set up between the two elevators. The ship island can only appear At the front of the hull.

The medium-sized aircraft carrier with a displacement of 45,000 tons in front of us has a more unusual design. It is further forward than the island of the aircraft carrier Charles de Gaulle. The Charles de Gaulle can at least park one or two fighter jets in front of the island. The ship in front of her has one. You can't even stop, this is a proper rhythm to charge forward!

 Shaoyigu was unable to answer again and looked at Sokolov.

Sokolov said lightly: "This is of course for the convenience of commanding operations. It is not only an aircraft carrier, but also an amphibious assault ship. When commanding landing operations, it is of course more appropriate to be closer to the front."

I see!

Shaoyigu felt admiration in his heart. He still needs to study more in the future. Look at our chief designer. He can answer all kinds of questions easily, but he can't do it and can only hold it back here.

 There is still a lot of knowledge that I need to learn.

Chaudhary nodded and agreed with these introductions. Just like that, he asked a dozen more questions in a row before leaving with satisfaction.

"He should be sent by Asan Navy. After he returns, he will definitely give a detailed report to Asan Navy. In this way, our design can be put to the senior officials of Asan Navy. They will definitely come to ask for help. ."

Shaoyigu spoke with some difficulty: "Mr. Chief Engineer, why don't we go door-to-door to sell?"

"Door-to-door sales? Our Neva Design Bureau is the largest in the country and the largest and most professional warship design organization in the world. When did we need to stoop to door-to-door sales? If customers like our products, they will naturally come to our doors. Come for help!”

Shoigu is a young designer. After entering the Neva Design Bureau, the Red Empire has begun to decline, so he does not feel so proud. However, Sokolov is different. In Sokolov's youth, It was the most glorious era of the Red Empire and the most glorious era of the Neva Design Bureau. They designed three motherships in one breath. It was the Red Empire and the most powerful warship design bureau in the world. You want him to come to sell it? Can't do it.

 Exhibiting publicly at the International Defense Exhibition is already his bottom line. If customers are interested in it, they will naturally come to him for help.

Shaoyigu was very helpless, but since the chief commander said so, he had no other choice.

 After leaving the booth here, Choudary was still a little excited. This design still looks quite good!

 The excited Choudary continued walking along the inner road, and then saw a booth surrounded by a large group of people.

 Where is this place and why is it so popular? He looked up at the sign above.

 Mingzhou Group?

Hum, this group just knows how to show off, and I’m not interested in it!

However, at this moment, someone inside suddenly stood on the booth, and he suddenly stood out from the crowd. These reporters did not have to squeeze, and the people behind could see clearly. Their cameras were focused on the hand held by this person. Something, a burst of shooting.

Chaudhary was stunned when he saw what was in the man's hand. The next moment, he picked up the camera and quickly adjusted the focus.

 In the field of vision, a beautiful aircraft carrier model appeared.

The whole model has a metallic luster, looks very good in texture, and the details are so lifelike. I really don’t know how it was made. Moreover, the half-meter-long model, even if it is a shell, probably weighs dozens of kilograms. The other party took it easily.

At this time, before he pressed the shutter, the other party turned the object in his hand ninety degrees: "Now, please take a bird's-eye view."

Originally, the model was placed normally, so what I saw was a side view. I was blinded by the shiny appearance. I couldn't see it very clearly. I could only vaguely see a model of an aircraft carrier taking off by ski jump. However, when it was seen from the side When he turned ninety degrees and saw the overhead view, Choudary was completely stunned.

 What kind of design is this? Isn’t it too weird?

Beveled deck, leaping deck, these are nothing to see, they are quite satisfactory, but what about the ship island?

 There is a ship island in the front and another ship island in the back. This thing is actually a double island layout? How come there is such an unusual design? The only one in the world!

At this time, Yang Dawei, who was holding the model, was introducing to everyone: "Our aircraft carrier is an aircraft carrier with a full load displacement of 45,000 tons. Its biggest feature is its dual-island structure."

“Excuse me, why do you design it this way?” Someone shouted below.

"Please don't make any noise. I know what you want to ask, so please listen to me first. I will explain the relevant design ideas to you. After I finish explaining, if you have any questions, please ask. May I?"

 Everyone couldn't help but quiet down, listening to Yang Dawei's introduction.

"First of all, we consider the intake and exhaust issues of the gas turbine. Everyone knows that the intake and exhaust required by the gas turbine are much larger than other power systems, which requires a thicker chimney. The American aircraft carrier is designed with a small Because others use nuclear power and do not need intake and exhaust, ours cannot. In order to reduce the length of the intake and exhaust system pipes, we designed two islands at the front and rear."

When he heard this, Choudary suddenly understood: the 1143F design plan of the Neva Design Bureau was simply nonsense.

In the design drawing, the gas turbine was placed at the back and the ship island was placed at the front. When he just looked at it, he felt very curious. Now he understands that there is no special chimney in the design drawing. !

That island is very beautiful. It was obviously inspired by the American and French island designs. It is quite simple, but there is no chimney!

If a gas turbine is used, the intake and exhaust volume will be quite large, and the chimney will be quite thick. The decades of history and the fact that three aircraft carriers have been designed are all nonsense, and even a chimney has been forgotten!

“However, with your design, the distance between the front island and the stern is very far, and the intake and exhaust pipes will be very long!” Choudary couldn’t help but speak.

Countless eyes looked at Choudary, and their eyes were full of complaints. Did you hear it clearly? Just now, what I said was very clear. Don't interrupt. Wait until they explain. Then ask questions after the explanation. Why are you so rude and incompetent?

"Please don't ask any more questions. Let me explain first." Yang Dawei continued: "We can also explain the problem of this intake and exhaust system first. According to the customer's needs, if it can reach a speed of about twenty knots, , then it is enough for us to arrange two gas turbines. If we want to reach a speed of thirty knots, we need to arrange four gas turbines. According to the different needs of the customer, there can be a layout plan of two, three, or four units. .”

No one spoke anymore, only Yang Dawei introduced: "If the layout is based on two gas turbines, then the engines can be placed under the ship island at the back. If there are four, then they will be placed under the ship island at the front. , add two more.”

Chaudhari wanted to ask again, but finally shut up.

Yang Dawei did not let him wait long and continued to introduce: "It should be easier for everyone to understand the two units. The power can be transmitted directly to the rear through the transmission shaft to complete the drive of the warship. If there are four units, then we will A comprehensive electric drive solution will be adopted, with all four gas turbines used to generate electricity, and the electricity generated will be used to drive the electric motor at the tail and drive the propeller, thus avoiding the problem of the drive shaft."

 Integrated electric drive!

 This is definitely a new concept!

Although this kind of design has already begun to be used on submarines, the diesel engine is only used to generate electricity, drive the electric motor at the tail, and drive the propeller. However, submarines are small after all. Diesel-electric submarines are only several thousand tons, and this aircraft carrier in front of us , that is a displacement of 45,000 tons. Such a heavy aircraft carrier actually uses integrated electric drive?

 Is this okay?

"We have already conducted relevant research." Yang Dawei continued: "Our integrated electric drive system has begun to mature gradually. It is no problem to use it on aircraft carriers. Only this kind of system can realize the power of medium-sized aircraft carriers on gas turbines. Target. At the same time, this system has more benefits, such as being able to allocate appropriate power to the aircraft carrier, for example, it can provide energy to our electromagnetic catapult."

Electromagnetic catapult!

Yang Dawei proposed a new plan.

 Steam catapults have long been outdated. Our design uses an electromagnetic catapult!

"Although we use the method of jumping from the deck, a catapult is still arranged on the angled deck. This catapult is planned to use electromagnetic ejection and can take off carrier-based early warning aircraft, carrier-based anti-submarine aircraft and other aircraft types." Yang Dawei introduced. Tumo Xingzi Splash: "We also have relevant technical reserves. After all, as long as a gas turbine is used, it is insulated from the steam catapult and can only use the electromagnetic catapult."

Yang Dawei’s statement once again shocked everyone. In the mid-to-late 1990s, something as high-end as an electromagnetic catapult was actually launched? You actually said you were mature?

“Steam can be heated using waste heat from a gas turbine.”

Chaudhary could not hold back and continued to speak.

After hearing what he said, Yang Dawei smiled: "Waste heat can indeed heat steam, but it is impossible to heat it for use in a steam catapult. The gentleman who asked the question, it seems that you are also an expert in this field. Do you know how high the air pressure is in a steam catapult? How much steam does a single ejection consume?"

Chaudhary's face turned a little pale. He could tell with just a little thought that it was absolutely impossible! As for the waste heat of the gas turbine, it is almost enough to burn a boiler to drive a steam turbine to generate electricity. It is absolutely impossible to use it for a steam catapult.

 It’s all the fault of the Neva Design Bureau! How could I be so credulous in what the Neva Design Bureau said? The Red Empire has collapsed. Many outstanding designers in the Neva Design Bureau have gone to the West. The remaining people are a bunch of idiots.

How could I be deceived?

Chaudhary was very annoyed.

"You may think that electromagnetic catapults are still far away, but I can tell you that these technologies are not Star Wars. They will be applied to our lives. The emergence of maglev trains and the like has already given us reserves for electromagnetic catapults. We have enough technology. Well, let’s go back to the two-ship island. There are many, many advantages to this design.”

Yang Dawei continued to introduce.

Chaudhary looked at it there in a daze. He couldn't even think. The design concepts of the Orientals were so advanced that they simply led the entire era!

Remembering that even a destroyer in China had to rely on Lao Maozi's design drawings, he felt a sense of humiliation deep in his heart. When did the Orientals become so powerful?

 They not only engage in design, but also have many finished products.

If our own side wants to build an aircraft carrier, the most suitable way is probably to buy the blueprints from the Orientals, right?

Thinking of this, he felt even more ashamed.
