The rising sun shines over the South Asian subcontinent and shines on the huge dockyard of the Cochin Shipyard.
There is a huge warship here.
The bow of the ship is the jump deck, and the left side is the angled deck. It looks full of modernity. There is a huge island-shaped building on the right side of the ship. The building is square and gradually gets larger upwards, forming an inverted trapezoidal cross-sectional layout. The ship island
There is also a quadrilateral structure on the top of the front, with three holes on all sides. It seems that it is for the placement of a special phased array radar.
However, look at the rear of this structure. The tall mast just blocks all the view from behind, so the last phased array radar antenna is arranged at the rear of the entire building.
There is no chimney in the center of the ship island. The right side slopes outward, and four circular tube-shaped openings are arranged here. This is the chimney of the aircraft carrier.
The ship island is very large, and Lao Maozi designed it in this style. There is an elevator at the front and rear of the ship island. The area of the elevator is not large, so it makes up for some gaps.
At this time, all the scaffolding above has been removed, the hull has been painted with navy gray, and the skeletal dragon parts are dark. Such an aircraft carrier already looks like it is taking shape.
A podium was set up in the open space of the shipyard, and Sunil, who was full of excitement, was delivering a speech there.
"Today, we are very happy, we have ushered in the day when the Blue Sky Guardian will be launched!"
This sounds a bit funny, because Sunil once said this here a few years ago. At that time, the Blue Sky Guardian was still a semi-finished product and was launched into the water for the first time. There was no beveled deck and the deck at the tail was not repaired.
Qi looked very weird, but just like that, he was announced to be launched into the water by the Asan Navy in a high-profile manner.
A lot of things happened at that time, and even the dock was not strong enough. Although the locks had been opened, silt accumulated outside, making it impossible for the warship to get out.
Of course Ah San will learn his lesson this time and has already cleaned up the dock door, and it is in complete condition this time!
After so many years of preparation, their aircraft carrier is finally going to be launched! Compared with the last time, they will not come back after this launch, it will be a complete launch!
The camera was also filming, recording the entire launching process. Everything in the dock, from the bow to the stern, was clearly illuminated.
"Our Asan shipbuilding industry is the most powerful. When we launch this time, we will use self-propulsion to leave the dock, because our aircraft carrier has already installed all the power systems in the dock!"
If it is a normal launching method, in order to avoid the impact of water flow and damaging the propeller, you will usually choose to install the propeller after launching. However, it does not matter in the dock. The water flow comes in slowly. After entering, it will be almost the same as normal sailing. If the power system is complete
, of course you can sail normally after launching it into the water.
Because there was a problem in the last launch, Ah San and the others have been holding back their anger. They must do a better job this time and let people know about the progress of Ah San's shipbuilding industry!
Although the construction of the Dongfang 003 aircraft carrier was not announced to the outside world, the first part of the aircraft carrier that was quickly built in the dock has attracted the attention of the intelligence agencies of many countries. It is obvious that it is an aircraft carrier with a huge displacement, even larger than the previous 002 aircraft carrier.
Even bigger!
This kind of aircraft carrier cannot be exported and can only be used for own use. Ah San also knows that Dongfang is building an aircraft carrier with a displacement of more than 80,000 tons, and they, this 40,000-ton aircraft carrier has just been launched, and they are already lagging behind.
There must be some innovation.
Of course they don't know that Dongfang's aircraft carrier also had all these installed when it was launched, and even carried out a lot of outfitting work, but it was in better condition than Asan's aircraft carrier when it was launched.
However, even if Ah San knew about it, he would ignore it. In short, their aircraft carrier can be launched after being launched into the water. This is a new miracle.
"Now, let me introduce to you our aircraft carrier main engine. This aircraft carrier uses four LM2500 gas turbines as power. It is the first aircraft carrier in the world to use gas turbines!"
This is even more nonsense. The Mingzhou Group built gas turbines for big companies and the Guinea Navy, but Sunil obviously ignored these and pretended to have seen nothing but his own aircraft carrier.
"The British aircraft carrier also plans to use gas turbines, but it is slower than ours. Therefore, our aircraft carrier is the most powerful aircraft carrier of this era! Those aircraft carriers that burn boilers are outdated. An aircraft carrier must use a gas turbine to be considered an advanced aircraft carrier.
Even nuclear-powered aircraft carriers cannot match the acceleration of gas turbine aircraft carriers!”
When thinking of this, Sunil suddenly had an idea and added: "After it is launched into the water, our aircraft carrier will drive around on the water to show everyone our best gas turbine power!"
When they heard him say this, the other technicians present frowned.
What are you talking about? Even if you launch the engine into the water, you actually want to make this aircraft carrier make a lap on the sea? Are you out of your mind?
It’s not equipped yet and it’s empty inside. Should the helmsman stand there and use a wrench to tighten the nut of the steering gear to start it? What if something goes wrong?
However, now that Sunil said it in front of so many people, it must be done, and they couldn't help but curse in their hearts.
"We use four LM2500 gas turbines with a total power of more than 100,000 horsepower, which is larger than the Queen-class aircraft carrier with a displacement of 60,000 tons. Therefore, the speed of our aircraft carrier can reach more than 28 knots!"
Sweat suddenly appeared on the forehead of the person in charge below. Brother, please stop talking nonsense. If you continue talking, we will have to sail at full speed on the sea? This kind of experiment is after the outfitting is completed.
It will take some time for the sea trial to be completed.
Do you think too highly of our Cochin Shipyard?
Although he was anxious, he couldn't go up to dissuade him. He could only stamp his feet below.
This chapter is not over yet, please click on the next page to continue reading the exciting content! Fortunately, Sunil did not continue to talk nonsense, but changed the topic.
"Our Stan Aviation has purchased the production license for this gas turbine, and we can produce this gas turbine at our own place in the future." Sunil continued: "In the future, our naval power, from frigates to aircraft carriers, will be
We will exclusively use the world’s most advanced LM2500 gas turbine!”
There was another burst of applause below, but many people were muttering, Stan Airlines? Do we dare to use the products produced by this company?
Finally, the speech ended.
"Now, I declare that the launching ceremony has officially begun!"
Although he had smashed the wine bottle last time, Ah San was not stingy with such a bottle of wine. For an aircraft carrier, he was willing to smash three or five bottles, so he held the wine bottle smashing ceremony again.
At this time, light blue smoke was rising from the chimney of the aircraft carrier, and the roar of the engine sounded. The aircraft carrier had started its engine!
Bang! The wine bottle hit the bow of the ship, causing foam to fly.
"Fill in water and open the gate!"
The turbulent sea water poured in, and the huge ship body shook and floated easily.
"Reverse!"
The power turbine rotated, the power was combined, water appeared from the rear of the aircraft carrier, and the huge hull slowly retreated.
"Did everyone see it? Our aircraft carrier left the dock under its own power. This is a new miracle in the history of world shipbuilding. Our Asan shipbuilding industry is the strongest in the world!" Needless to say, Britain and France, Sunil even
The United States has been ignored. At this time, they themselves are the strongest.
Waves of applause came.
The roar of the engine rang in the sky, and a helicopter took off, carrying the photographer to the sea area where the aircraft carrier went to sea. Sunil said that the aircraft carrier would have to make a circle on the sea before it was outfitted.
At the pier, of course they had to follow and film a section.
On the unglazed ship island, several technicians frowned. Do they really want to do this?
"The helicopters have taken off, and we have no choice." A technician said: "Now, first adjust the retreat to the forward state."
"Copy that." came the response from the engine room: "Get ready to adjust the propeller."
Different hosts have different reversing methods. If it is a medium-speed or low-speed diesel engine, the propeller is directly driven and the diesel engine is reversed to achieve reversing.
As for gas turbines, some gas turbines have special reversing turbines. Just modify the gas turbine. Some have adjustable pitch propellers. Just change the propeller pitch to match the speed. Adjust to the opposite direction to achieve reversing.
.
Now it is in reverse state, and the propeller is in the opposite direction. As long as it is adjusted to the normal direction, the forward goal can be achieved.
Ah San had lofty goals. When he was building this aircraft carrier, he blindly pursued domestic products and requested domestically produced propellers. However, he found that he could not build it himself, so he urgently ordered it from Wärtsilä. Fortunately, he caught up.
Only Wärtsilä can produce variable-pitch propellers for this kind of aircraft carrier. This saves the gearbox. If there is no advanced propeller, you can only add a reverse gear to the gearbox, which is a big project.
The gas turbine rotates quickly and cannot directly drive the propeller, which requires a gearbox. At the same time, although the aircraft carrier Asan uses four LM2500s, it only has two propellers, so every two engines need to be paralleled. This is also
Parallel gears are required.
These are complicated enough, and it will be even more complicated if a reverse gear is added.
The huge aircraft carrier stopped and then switched to forward status.
The sea outside the shipyard has been cleared, and there is not a single ship in sight. The technicians began to speed up with an anxious mood.
accelerate!
The propeller at the tail rotated again, stirring the sea water and rolling up white foam. The huge hull began to move forward, getting faster and faster.
"Have you all seen it? Our aircraft carrier can be launched after it is launched into the water. It has combat capabilities, and our carrier-based aircraft can take off and land on it at any time!"
Sunil planned to continue to brag that they had purchased an advanced Rafale fighter jet. When this fighter jet enters service, it will definitely have the best combat capabilities. This is a fourth-generation aircraft and can fly at supersonic speeds!
But at this moment, someone shouted: "The aircraft carrier's condition seems wrong!"
"Yeah, why is it shaking up and down?"
"Look at the wake, it looks like fish bones!"
It can be seen more clearly in the sky.
The speed of the aircraft carrier was not very fast. As soon as it reached about ten knots, the bow of the ship began to shake up and down, as if it had encountered a huge wave.
It would be okay if it was just shaking up and down, but the key point is that the hull is still shaking left and right, and the waves at the tail can prove it all: in the normal wake, there are still some waves protruding, forming a fishbone-like shape.
This aircraft carrier is actually showing off!
This shows what?
Sunil's face darkened.
East.
"Hello everyone, welcome to this episode of Zhang Zhongshuo's show. Due to the special circumstances, we did not invite guests to the scene. We invited Pan Laolai from our 703 institute to be our guest through the Internet. He has already
You have been a guest on our show more than once, so you must be familiar with it."
The camera switched to Mr. Pan sitting in the study, waving to the camera: "Hello everyone, I am Mr. Pan. I am very happy to meet you all again."
"Recently, Asan's aircraft carrier was launched. They installed a power system this time, so they showed it off when it was launched. However, it was precisely because of the show that we saw the problems of this aircraft carrier. It
When it only reaches a speed of ten knots, it starts to shake left and right and up and down. Some people say that this is because there is no bulbous bow. Mr. Pan, can you analyze it for us?"
"Okay, host." The camera continued to switch to Mr. Pan, and Mr. Pan began to explain.
This chapter is not over, please click the next page to continue reading! "The bulbous bow is a great invention for ships. With it, ships can reduce resistance, increase speed, and reduce fuel consumption. The greater the speed, the more obvious the effect.
So we can see that some particularly slow cargo ships may not have a bulbous bow, but as long as the speed can reach more than 15 knots, they must have a bulbous bow. Asan claims that his aircraft carrier can reach 28 knots, but it does not
The bulbous bow is very rare, and if we guess correctly, they probably can’t make it.”
"Can't make it?"
"Yes, just like the DSI bulge inlet, all aviation designers know that with this bulge, the boundary layer isolation plate and adjustment device can be replaced, saving weight, but now this device is applied to
We are the only ones on the plane, so why don’t other countries use it? Of course, it’s because they don’t know how to deal with it and process it. If its shape is slightly changed, the whole effect will be completely different.”
"I understand, this bulbous bow also requires high-precision processing. Asan doesn't have the processing technology, so it can't be processed. Is that so?"
"Yes, the bulbous bow of the warship is more complicated, and a slight change in appearance may have a counterproductive effect. With Asan's processing power, it is unlikely that it can be made up to standard, so they simply removed the bulbous bow.
"
"So, is this bulbous bow the cause of her swing?"
"That's not necessarily the case."
"not necessarily?"
"Yes, we can look at other aircraft carriers. The United States did not adopt a bulbous bow design before the Forrest-class aircraft carrier. For example, the Essex-class aircraft carrier with a displacement of more than 33,000 tons did not have this bulbous bow.
Bow, even if it sails to 30 knots, there will be no trouble."
It was World War II, and the Americans had no choice but to produce this thing in time. They produced 24 Essex-class aircraft carriers in one go. The process must be simplified, but even if the process is simplified, there will definitely not be any flaws.
question.
"What's the problem?"
"Let's discuss it separately. When a ship is sailing, there will be regular ship swings such as pitch, roll, and bow. The problem of bow is generally caused by the front being lighter and the rear being heavier, so when sailing
Constantly rising and falling, this problem can be solved by increasing the weight of the bow. However, roll and pitch are more fatal. Now these problems exist. The most likely reason is that Asan's aircraft carrier lacks reliable net stability during the design stage.
Strength testing, or the actual manufacturing process may have exceeded the original design of the aircraft carrier. Although Ah San said on the surface that this aircraft carrier was designed by himself, it was actually designed by Da Mao. Ordinarily, Da Mao would not have such a problem.
of."
It's not a design problem, it's a manufacturing problem, because Asan's manufacturing is not up to standard!
"Can it be changed?"
"Rolling should be relatively easy to solve. For example, the French Charles de Gaulle has a small displacement and uses a special anti-rolling device to reduce the left and right rolling. Ah San can import a set of the same type from France, but pitching is difficult.
After all, the hull is too huge. If you want a professional device to reduce the pitch, it means that the damping moment must be very large, and it must be able to act on half of the hull."
"That means that this defect of the Asan Navy's aircraft carrier cannot be solved?"
"Yes, it is difficult to solve. Regardless of rolling or pitching, it will bring major hidden dangers to the take-off and landing of carrier-based aircraft. The carrier-based aircraft pilots of the Asan Navy will have a narrow escape every time they land in the future. In fact, even if
Even the bow shaking is not easy to solve. After all, we know that the aircraft carrier needs to add blocking devices at the tail. These devices will also greatly increase the weight behind the aircraft carrier. In other words, after the aircraft carrier is outfitted, the shaking will be even more severe.
.”
In front of the TV, someone cursed.
"Damn it, this loyalty program has been smearing our Asan shipbuilding industry, but we are not that bad!" Sunil clenched his fists.
"Yes, we can guarantee that there will be absolutely no problems with our own construction work." The person in charge of the shipyard said quickly.
Since there is no problem with construction, it is a design problem!
"Contact Damao immediately and we will ask them to give us an explanation!" Sunil said.
If this kind of problem occurs on the aircraft carrier, Ah San will not take the blame. It must be a design problem. No reliable net stability test was conducted during the design!
Da Mao's design bureau has long since declined. I originally thought they could produce qualified drawings, but I didn't expect so many problems to arise!
"yes."
It was good to have the Internet, and soon the designers of the Northern Design Bureau appeared on the computer screen.
"Mr. Mising, there is a problem with your design drawings!" Sunil said with a gloomy face: "The Blue Sky Guardian we built according to your drawings encountered major problems in the first sea trial. You must
You have to give us an explanation!"
Misin's face was also displeased: "Your first sea trial? What are the conditions for the sea trial? You idiots who don't act in accordance with scientific laws!"
This statement made everyone confused.
"What's wrong?"
"First outfitting, then sea trials, this is the normal procedure. Now, there is still a lot of equipment on the warship that has not been installed. If you drive an empty shell, can you not shake it? You drive an empty car and a fully loaded one.
When a car is driving on the highway, will the former sway? Will the latter sway?" Misin said: "You idiots, you didn't even see the problem in Zhang Zhong said the program, they deliberately missed the biggest
The reason is that the sea trial was carried out without outfitting, the ship’s weight was insufficient, and the weight distribution was wrong!”
Everyone suddenly realized.
That's right, when our side conducts sea trials before outfitting, the warship is just an empty shell. Of course it will shake. When the outfit is completed and various equipment is installed, of course it will stabilize!
This chapter is not over yet, please click on the next page to continue reading! Why didn't we think of this reason? It's so stupid.
"I'm sorry, Mr. Mising, we were reckless."
"There will definitely be no problems with our design drawings, and we can guarantee it with our reputation!"
When the video contact ended, Misin let out a long breath.
"Mr. Mising, what if it's really our problem?" the assistant asked: "After all, we really didn't do that kind of test."
"Ah San won't be able to complete the outfitting if he doesn't have three to five years. The sea trial will be done only after completion. I will have retired by then. But you don't have to worry. You can also tell Ah San that it is also creating problems." Mi
Xin said: "Asan used their own steel, which caused vibrations in the hull. What does this have to do with our design? If they want to solve the problem, they can pay us to provide technical support."
The assistant nodded and put down a big stone in his heart.
That's right, this is how you should treat Ah San.
"It turns out that the reason is that we don't have outfitting." Sunil said: "As long as the aircraft carrier is outfitted and then undergoes sea trials, this problem will not occur."
"Really? Then we can rest assured."
"Report, good news!"
"explain!"
"The first batch of three Rafale M fighter jets will be delivered soon!"
"Really? That's great. Don't you think the order will be queued for a long time?"
"Yes, the order has been queued for a long time, and the French Air Force has not received the goods yet. What we have now was originally produced for the French Air Force."
There are many models of Rafale. The original A type was a technical prototype that first flew in 1986. The B type and C type were the two-seat and single-seat models of the Air Force respectively. They were only eligible for delivery in 2004. The Navy's M type was
A single- and double-seater model began service in 2002.
After the French Navy got a few of them, it gave the order to Ah San and let Ah San equip them first to avoid Ah San regretting it.
Now, the first batch of three Rafale fighter jets are about to be delivered to Asan. For Asan, this is another good opportunity to increase his national defense strength!
"Great, when will I receive it? We are going to have a lively acceptance ceremony!"
