Chapter 533 No Contrast No Harm

   Choudary walked into the indoor showroom of naval equipment.

Of course Ah San's senior naval officers would not come to the East to participate in this kind of defense exhibition. Doing so would only increase the face of the Orientals and destroy their own prestige. However, they are looking forward to this time very much, so, Some of their eyeliners were dispatched.

  Chowdari is one of Sunil's subordinates. At this time, he is wearing a suit and leather shoes. He is dressed like a reporter. On the card on his chest, the unit name of Ah San Times is also written.

  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 the Neva Design Bureau quickly attracted his attention, and 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 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 drawing of the Neva Design Bureau is also big enough. It is placed on a two-meter-wide and one-meter-high drawing board. On it is the main work of their design bureau: the 1143E nuclear-powered aircraft carrier.

"This is the nuclear-powered aircraft carrier we designed with a displacement of 90,000 tons, demonstrating the most powerful warship design capability of our Neva Design Bureau." Shoigu, a young designer from the Design Bureau, looked at the people who came over from the outside, especially Ah San. The Times reporter 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 drawings of this aircraft carrier were not for the Asan Navy.

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

  However, facing the enthusiastic Shoigu, of course he has to listen patiently.

"The length of this aircraft carrier is 350 meters. Its front is a jumping deck, which can be used to take off by ski jumping. The Su-33 carrier-based aircraft on it is dispatched. There are two ejectors on its inclined deck. It can catapult and launch carrier-based early warning aircraft and other aircraft. Its comprehensive combat capability is comparable to that of the Nimitz-class aircraft carrier in the United States. The total number of aircraft on board will exceed 90."

  In the whole world, only Da Mao can keep pace with the United States and design a similar aircraft carrier. Other countries simply don't 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. Now, it has become the same as Western aircraft carriers, just as a platform for carrying fighter jets.

  No matter what, this well-behaved design can still attract some people's attention.

  Chowdary faced the design drawing and snapped a few photos.

   "If you are interested, you can do a special report, and we are willing to accept interview questions." Shoigu continued to introduce.

   "Excuse me, do you only have such an aircraft carrier design drawing?" Shoigu asked.

   "Of course not, you come here, we also have a general-purpose maritime combat complex." Shoigu introduced.

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

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

   "Come here and take a look." Shoigu led Chaudhary around half a circle, and when he went to the other side of the booth, he saw another aircraft carrier with a distinctive shape.

  When he saw this blueprint, Choudhari's eyes widened. It looked good!

   With one frantic press of the shutter button, Chaudhary took several photos.

Shoigu was very satisfied: "The design of our 1143F adopts a common method. Two catapults are arranged on the bow, which can eject and take off various carrier-based aircraft. There is also an angled deck for aircraft to land. 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 still good for our side! Chaudhary's heart was filled with anticipation.

   "However, why did you name it the Common Maritime Combat Complex instead of an aircraft carrier?" Chaudhary asked curiously.

"Look at the back. At the rear of this warship, there is a special dock. 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. Landing operations across the sea."

  It is a complex, not just an aircraft carrier, but also an amphibious assault ship. This design is too weird, right?

   "Our Ah San Times will publish a special report on this aircraft carrier." Chaudhary said, "Do you have any other information?"

  Generally speaking, people who come to defense exhibitions not only have things on the booth, but also beautifully printed brochures. As long as he has the brochures, he can compile news reports.

   Shoigu had a shameful smile on his face: "I'm sorry, we don't have such information yet."

No?

  They came here too hastily, they didn’t prepare anything, and of course they didn’t have any special materials. At this time, after hearing Shoigu’s introduction, Choudary was a little speechless. This is your first time participating in the International Defense Exhibition, right?

  For the Neva Design Bureau, this is really the first time. It is already good enough that they can draw a large-scale design. There is no model, no promotional materials, and there is as much haste as possible.

   "However, if you have any questions, you can ask us anytime." Shoigu replied.

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

   "Of course, if the Red Empire has not collapsed, then our Ulyanovsk has already installed a special steam catapult. In this regard, we still have technical reserves."

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

"Considering that the boiler is not safe, our aircraft carrier plans to use gas turbines. At present, our domestic relevant institutions are conducting research. You can go to the booth of the Saturn Consortium next door to us and have a look. They have relevant plans." Shoigu introduced Very thoughtful.

"Gas turbines are good, but we want to know, how does a gas turbine-powered aircraft carrier burn boilers and provide energy for steam catapults?" Chaudhary's words immediately made Shoigu speechless .

   Yes, why didn’t you take this issue into consideration when designing it?

  Without a boiler, how to boil water, without steam, how to provide energy for the catapult?

  Because during the trial voyage of Chaoriwang, eight boilers blew up seven of them. Therefore, in order to satisfy potential customers, their Neva Design Bureau decided to switch to gas turbines. It happened that the Saturn Consortium was developing related gas turbines. They hit it off.

  Their design was hasty, and they forgot these problems. Who would have thought that they would be pointed out sharply 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 while and immediately answered: "Tell him, we use the exhaust gas of the gas turbine to burn the boiler!"

  Shoigu's eyes are full of admiration, the chief designer is amazing! Although the big guys haven't considered this issue, the chief designer can easily find an excuse!

  The exhaust temperature of the gas turbine is also very high. In order to avoid being tracked by thermally radiating missiles, the exhaust ducts of warships have to be heat-dissipated. Either open cooling holes or directly use seawater to dissipate heat. The heat is actually wasted.

   But now, the aircraft carrier in front of me has been improved, and the exhaust gas of the gas turbine has been reused, which perfectly solves the problem, what a creative 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 a large aircraft carrier, the take-off area and landing area of ​​the carrier-based aircraft are far away. In order to take into account the take-off and landing, elevators are often located at the front and rear of the hull, so that the island is arranged in the center, with elevators at the front and rear.

  However, medium-sized aircraft carriers do not have this advantage. Take 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 the take-off area 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 different: the elevator is placed in the middle and the rear, and the parking area is set between the two elevators. The ship island can only appear at the front of the hull.

And the medium-sized aircraft carrier with a displacement of 45,000 tons in front of me has a more unique design. It is further forward than the island of the Charles de Gaulle aircraft carrier. Can't even stop, this is a proper rhythm to charge forward!

   Shoigu couldn't answer again, and looked at Sokolov.

   Sokolov said lightly: "Of course, this is 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 at the front."

I see!

  Shoigu was full of admiration in his heart, and he still needs to learn more in the future. Look at our chief designer, who can answer all kinds of questions easily, but he can't do it himself, so he can only hold back here.

  I still have a lot to learn.

   Choudary nodded, agreeing to these introductions, and just like that, asked more than a dozen questions in a row before leaving in satisfaction.

"He should be sent by the Asan Navy. After returning, he will definitely report to the Asan Navy in detail. In this way, our design can be placed with the senior management of the Ahsan Navy. They will definitely come to ask for help. .”

   Shoigu said with some difficulty: "Mr. Chief Teacher, why don't we come to sell?"

"Door-to-door? Our Neva Design Bureau is the largest in China and the largest and most professional warship design organization in the world. When did we need to degenerate to the point of door-to-door sales? Customers are interested in our products, so they will naturally come to our door Come for help!"

Shoigu is a young designer. After entering the Neva Design Bureau, the Red Empire has begun to decline, so he doesn't feel so proud. However, Sokolov is different. 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 go. It was the Red Empire and the most powerful warship design bureau in the entire world. Want him to come to sell them? can't do it.

  Publicly exhibiting here at the International Defense Exhibition is already his bottom line. If customers are interested, they will naturally come to the door for help.

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

   Leaving the booth here, Choudary was still a little excited. This design still looks pretty good!

   Excited, Chaudhary continued walking along the inner road, and then saw a booth surrounded by a large group of people.

   Where, why is it so popular? He looked up at the sign above.

  Mingzhou Group?

  Hmph, this group just knows how to show off, so I'm not interested in it!

However, at this moment, someone inside suddenly stood on the booth, and suddenly stood out from the crowd. These reporters didn't have to squeeze, and the people behind could see clearly. Their cameras were aimed at the man holding in his hand Something, a burst of shooting.

  Chowdary was taken aback when he saw the thing 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. It looks very good in texture and the details are so realistic. I really don’t know how it was made. Moreover, the half-meter-long model, even if it is a shell, probably weighs tens of kilograms. The other party took it easily.

   At this time, before he pressed the shutter, the other party turned the object 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 caught by the shiny appearance, and I couldn’t see it very clearly. I could only vaguely see that it was a ski-jump aircraft carrier model. Turning ninety degrees, Choudary was completely stunned when he saw the top view.

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

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

  There is a ship island in the front and a ship island in the back. This thing is actually a layout of two ship islands? How can there be such an alternative design? The only one in the world!

  At this time, Yang Dawei, holding the model, was introducing to everyone there: "Our aircraft carrier is a fully loaded aircraft carrier with a displacement of 45,000 tons. Its biggest feature is the structure of two islands."

   "Excuse me, why did you design this way?" someone shouted below.

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

   Everyone could not help but quiet down, listening to Yang Dawei's introduction.

"First of all, what we consider is the intake and exhaust of gas turbines. Everyone knows that the intake and exhaust of gas turbines is much larger than that of other power systems, which requires thicker chimneys. The US aircraft carrier is designed with a small chimney. Because people use nuclear power and don’t need intake and exhaust, ours can’t work. 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 is simply nonsense.

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

  The ship island is very beautiful, obviously inspired by the design drawings of the American and French ship islands, it is quite simple, but there is no chimney!

  If gas turbines are used, the intake and exhaust volume will be quite large, and the chimney will be quite thick. The decades of history and the design of three aircraft carriers are pure nonsense, and even a chimney has been forgotten!

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

  Countless gazes looked at Choudhary, their gazes were full of complaints, did you hear clearly? Just now, he made it very clear, please don't interrupt, wait for someone to explain, and then ask questions after explaining, why are you so rude and unqualified?

"Please don't ask any more questions, let me explain first." Yang Dawei continued: "We can also explain the problem of the intake and exhaust system first. According to the needs of customers, if the speed can reach about 20 knots , then it is enough for us to arrange two gas turbines. If we want to achieve a speed of 30 knots, we need to arrange four gas turbines. According to different needs of customers, we can have two, three, or four layout schemes .”

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

  Chowdary wanted to ask again, but finally shut up.

Yang Dawei didn't make him wait long, and continued to introduce: "It should be easier for everyone to understand the two sets. The power can be transmitted directly to the rear through the transmission shaft, and the drive of the warship can be completed. If there are four sets, then we will A comprehensive electric drive scheme will be adopted, and all four gas turbines will be 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, but the submarine is small after all, and the diesel-electric submarine is only a few thousand tons, and the aircraft carrier in front of it , that is a displacement of 45,000 tons, such a heavy aircraft carrier, actually uses integrated electric drive?

   Will this work?

"We have already carried out relevant research." Yang Dawei continued: "Our integrated electric drive system has gradually matured, and it is no problem to use it on an aircraft carrier. Only this system can realize the gas turbine on a medium-sized aircraft carrier. Target. At the same time, this system has more benefits, for example, it can distribute the appropriate power to the aircraft carrier, for example, it can provide energy for our electromagnetic catapults.”

   Electromagnetic Catapult!

  Yang Dawei proposed a new plan.

  What kind of steam catapult is out of date, our design uses an electromagnetic catapult!

"Although we use the method of jumping over the deck, a catapult is still arranged on the inclined deck. This catapult is planned to use electromagnetic ejection, which can take off ship-borne early warning aircraft, ship-borne anti-submarine aircraft and other types." Yang Dawei introduced Spitting Star Splash: "We also have the relevant technical reserves. After all, as long as the gas turbine is used, it will be insulated from the steam catapult, and it can only be used with an electromagnetic catapult."

  Yang Dawei's statement shocked everyone again. In the mid-to-late 1990s, something as tall as an electromagnetic catapult was thrown out? You still say you're mature?

   "The waste heat of a gas turbine can be used to heat steam."

   Choudary didn't hold back, and continued to speak.

Hearing his words, Yang Dawei smiled: "It is true that waste heat can heat steam, but it is impossible to heat it enough to be used by steam catapults. The gentleman who asked the question, it seems that you are also an expert in this field. Can you know how high the air pressure of the steam catapult is? How much steam is consumed for one ejection?"

  Chowdari's face turned pale, and he could tell with a little brainstorming that it was absolutely impossible! As far as the waste heat of the gas turbine is concerned, it is almost impossible 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 Neva Design Bureau! How could I be so credulous about what the Neva Design Bureau said? The Red Empire has collapsed, and many outstanding designers in the Neva Design Bureau have gone to the West, and the rest of them are a bunch of idiots.

  How could I be fooled?

   Choudary was 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 our electromagnetic catapults a reserve. It has enough technology. Well, let’s go back to the two-ship island, there are many advantages to this design.”

   Yang Dawei continued to introduce.

   Choudary was so dazed looking there that he couldn’t even think about it. The design concepts of the Orientals are so advanced that they have led the entire era!

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

  They not only engage in design, but also have a lot of finished products.

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

  Thinking of this, he felt even more ashamed.
