Great warships

Chapter 733
After wandering around Genghis Khan Airlines for a long time, at night, everyone left and went to the airport by car.

"Taozi, can that D-18T engine really develop into a 40MW gas turbine?" In the car, Wu Shengli couldn't wait to discuss with Qin Tao.

"Yes." Qin Tao nodded: "Forty megawatts is the foundation, and it can be expanded to fifty megawatts or even higher in the future. After all, the foundation is there."

The LM6000 gas turbine has a basic output of 15 kilowatts at an ambient temperature of 42385 degrees Celsius and an altitude of sea level, with a thermal efficiency of over 40.00%. At the same time, if you want to further increase the output power, you can inject water to increase the power to 492000 kilowatts, thermal efficiency close to 50.00%.

The contemporary D-18T, of course, can also reach this level. If the current technology is used to improve, the power can be increased by a large amount. If the development of the LM2500 gas turbine is followed, the final power can be doubled.

"If this gas turbine can be successfully developed, then our warship power system will usher in another breakthrough." Wu Shengli is looking forward to it.

"Yes, a [-]-ton destroyer and a [-]-ton amphibious assault ship will have power reserves." Qin Tao said, "So, even if this project will cost a lot of money, our Mingzhou Group will firmly carry it out. .”

Wu Shengli opened his mouth wide. In the past, he would never have such a dream. Needless to say, destroyers of [-] tons and [-] tons were out of reach for a long time. What is the difference between a [-]-ton amphibious assault ship and an aircraft carrier?
"Taozi, in the past few years, you have been talking about amphibious assault ships. Will this thing overlap with our aircraft carrier?"

Qin Tao shook his head: "Of course not. The two combat methods are completely different. Look at the United States. In addition to aircraft carriers, there are also a large number of amphibious assault ships. The latest one is the Wasp class. Let's take the Wasp class. Come on."

The Wasp class was developed to replace the old Iwo Jima-class amphibious assault ship with the Tarawa-class amphibious assault ship. When it was designed, it had many new concepts. For example, it had to operate Sea Harrier fighter jets As well as air-cushion landing craft, the area of ​​the garage deck and warehouse deck in the hull has been reduced, just to load more Sea Harriers. In the later stage, the Sea Harriers were replaced with F-35Bs, and the combat effectiveness was further improved.

The Wasp-class amphibious assault ship began to be built in the 80s. When the eighth ship was built, it was already in 2002. This last ship has also undergone some improvements, especially the use of gas turbines to replace the previous boilers. With its replacement, the U.S. Navy completely abandoned the boiler.

Now, if the motherland's navy wants to grow stronger, it must not only have advanced aircraft carriers, but also have advanced amphibious assault ships. After all, the motherland's army still has a sacred mission to complete.

"The emergence of the Wasp class has given the US Marine Corps the ability to attack without approaching the beachhead. With the Sea Harrier fighter jet, it can better control the beachhead. At present, we already have the J-31A, which can be deployed on the beach. On the amphibious assault ship, moreover, we also have electromagnetic catapults, adding an electromagnetic catapult to the amphibious assault ship can allow fighter jets to eject, take off, and then land vertically. In this way, the performance of fighter jets will be even more powerful." Qin Tao Said: "Even, in some low-intensity conflicts, our amphibious assault ships can calm down the situation when they drive past."

Wu Shengli nodded. Aircraft carriers are very important, but they are too expensive and there will not be too many of them. In this way, when facing some low-level threats, dispatching an amphibious assault ship is enough.

It seems that this thing is necessary.

"Brother Tao, I just received the news that in the dock of our Mingzhou Group, the No. 002 and No. 1 cabins of the No. 2 aircraft carrier are about to be closed." At this moment, Zhao Ling spoke.

"What? It's about to start closing? This is an important moment, you have to go and have a look!" Qin Tao immediately became excited.

"Look what excites you, isn't it just the docking of the two cabins? Is there such a rush?" Wu Shengli was a little curious.

"Dad, do you know how many compartments our 002 aircraft carrier was divided into during construction?"

Segmented construction is already a standard shipbuilding method. A segment is built on the slipway, and another segment is built next to it. After the two segments are built, they are brought together and docked. Can greatly speed up the construction process.

Back then, in order to improve the construction progress of the heavy-duty aircraft-carrying cruiser, Makarov proposed this concept, and specially purchased a crane from Western Europe to carry it.

Now, of course, Mingzhou Group also uses this arrangement.

According to the different ships, the sections also vary in size. The best is the United Kingdom. When they built the Queen-class aircraft carrier, they only used four sections, one section at the bow, one section at the stern, and one section in the middle of the ship. The two sections are then started in different shipyards in England and Scotland. The advantage of this is of course that the construction progress is greatly accelerated. After the four sections are built, they are sent to a large shipyard in Scotland for closure.However, they dared to do this because they bought a super gantry crane from Dongfang, and after buying it, they sold it again, because no other ships needed such a big guy.

"How many segments?" Wu Shengli asked.

"Six sections. Even counting the ship island as one, that is seven sections." Qin Tao replied: "The first section and the second section start to connect, which means that the third section also needs to be connected." It can be said that the construction progress of our aircraft carrier hull has reached one-third."

"Six sections?" Wu Shengli was incomparably surprised: "How big should each section be!"

"It's really not small, but who makes our gantry crane powerful." Qin Tao said with a smile.

The queen-class aircraft carrier can be built in four sections, and the own side used six, which is too much. However, food needs to be eaten at a bite, and work needs to be done a little bit, so don't be too anxious.

After all, it is not yet the 21st century. If word of the construction of an aircraft carrier in six sections spreads, I don't know how many people will be envious.

"I'm going to take a look too." Wu Shengli said, he was very tempted.

Generally, shipbuilding starts from the bow, and aircraft carriers are no exception.

The first section only has the bow deck, but the second section starts to have an angled deck.

After arriving at the Mingzhou Shipyard, several people went straight to the dock. At this time, the two sections were slowly docking.

Wu Shengli felt his breathing quicken. Although there were only these two sections, he could still feel how huge the aircraft carrier was. The deck of the first section was straight and looked so spectacular. The deck has not been opened yet, and the installation of the electromagnetic catapult cannot be seen, but one can imagine in one's mind what a spectacular scene it will be.

The second aircraft carrier of the motherland is comparable to that of Kitty Hawk!
The parts where the segments are connected reveal more than a dozen layers of structure. The upper one is very high and belongs to the hangar position, while the middle one is shorter and is used for the crew’s living, dining, office and food storage warehouses.Further down, it will be higher and irregular. These are compartments for fuel, fresh water, ammunition, etc.

"There will be no error when the two segments are connected, right?" He became worried again.

Such a tall behemoth, what if there is an error when docking, and the docking is not aligned?
"Of course not." Makarov's voice sounded: "Leader Wu, 20 years ago, our warships built in sections could be perfectly docked, let alone now, every steel plate is bent by three-dimensional numerical control. The position of each welding seam is determined by laser, and even if there is an error, the accuracy will be maintained below 0.1mm. I have confidence in our construction quality."

Looking at the cabins being docked, Makarov was also heartbroken. The once huge red empire had disappeared, and he thought he was going to die in depression, but when he came to the East, he was reborn again!
"Old Ma, our construction progress is a little slow." Qin Tao said, "It took so long to come up with two sections."

"Mr. Qin, the progress is a bit slow. This is because the current section is the largest we have ever built. Therefore, we must ensure the quality of the construction and sum up experience. The next construction will be faster. We are confident that each The construction time of the sections is controlled within six months, so that in another two years, our hull construction will be completely completed, and we can launch it into the water by then."

It took two years to launch, another two years for outfitting, and another two years for sea trials!Of course, according to the original plan, the aircraft carrier will be launched in the new millennium. This calculation can still be a little faster than the progress, but Qin Tao still feels dissatisfied.

"Slow, it's too slow. After launching, there will be outfitting, and after outfitting, there will be sea trials." Qin Tao shook his head: "However, this is the first time we have built an [-]-ton aircraft carrier, and it is normal to be slow. After the experience, the next construction will be faster."

"Mr. Qin, during the staged construction, we have already completed part of the outfitting work, such as the installation of various internal pipelines, so we can save a lot of time for outfitting."

what?
This surprised Qin Tao: "Have all the pipelines been laid in the section?"

"Yes, we have learned from the experience of submarine construction," Makarov said.

Submarines are also built in sections, and they have to be outfitted during construction. Once they are welded, all kinds of large parts can't be plugged in. Qin Tao didn't expect that when his side was building the aircraft carrier in sections, the outfitting work would also be carried out. part of it.

"We have installed all the big parts, so as not to have to cut holes in the future. When it comes to the construction of the next few sections, the power system and the like must be installed in advance." Makarov continued: "So , after launching, the outfitting work should be completed within a year."

"Okay, the workers we built have worked hard! The technicians have also worked hard. When the day is launched, everyone will have a big red envelope!"

"The docking is complete, all the interfaces are correct, now start welding!" At this moment, Babbage shouted over there.

The two segments have been docked!
Relying on various advanced technologies, the two sections were built very accurately, which ensured a successful docking without any modification. Now, the welding can be started!

The first thing to be welded is of course the outside. On both sides of the side, the two mechanical arms that had been prepared for a long time rotated flexibly, and the sparks of the arc came out from the deck downward.

In order to improve the progress, a large number of welding robots have been used in the Mingzhou Shipyard. When welding the hull, robots play an important role. If there are no mechanical arms for welding, if only manual welding is used, then the subsection It will take a year or two to complete.

"Mingzhou Shipyard deserves to be the most modern shipyard in our country." Wu Shengli sighed: "The outer welds can be welded by machines, but I don't know what is used for the inner welds?"

"Large sections of welds can be welded by welding robots. Only small sections or those that are not convenient for the mechanical arm will be welded manually." Makarov said: "These machines are really good, and they are all made by our Mingzhou Group. It was developed, back then, if we had this kind of equipment, we would have built a nuclear-powered aircraft carrier a long time ago."

When talking about the past, Makarov still has regrets.

"Old Ma, don't worry, we will also use nuclear power for the next aircraft carrier, you have to pay attention to your health, you have to work for another 20 years."

Makarov nodded: "Well, Mr. Qin, I will work hard, and I will definitely live to that day."

"I really want to go up and have a look." Wu Shengli was a little greedy. Seeing that the two sections were combined together, and a third of the entire aircraft carrier came out, Wu Shengli really wanted to go up and have a look.

"Dad, you can't go up now, construction is going on everywhere, it's very dangerous, wait until the next few sections are closed and the aircraft carrier is launched, it won't be too late for you to go up and see."

Wu Shengli nodded: "Well, we still have to wait."

"President Qin, it's great that you're here!" At this moment, a person hurried over, and after seeing Qin Tao, he was very excited: "We have an improvement idea here, but, whether it is an aircraft carrier The design department, the construction department, and even the navy have all rejected our idea, and you have to decide for us!"

"Magong, after the aircraft carrier starts construction, the design drawings are frozen. If you modify it midway, it will waste a lot of time." Qin Tao said: "Your improvements can be put on the next aircraft carrier."

"President Qin, our improvement is very important! If we improve according to our plan, the aircraft carrier can operate more efficiently." Ma Ming said.

Qin Tao became a little curious: "What exactly do you want to improve?"

Electromagnetic ejection, electromagnetic interception, integrated power system of the whole ship, these high-end projects were all passed with the support of Qin Tao, and he was curious, what other projects did Ma Ming have?
"Electromagnetic elevator." Ma Ming said: "After our research and development, the technology of electromagnetic elevator has also been overcome. We can use this elevator to replace the original elevator, so that the aircraft carrier's elevator is more concise, and the carrier-based aircraft Scheduling is easier."

Wu Shengli became interested: "Electromagnetic elevator? What's the principle?"

On an aircraft carrier, elevators are a must. After all, the number of fighter planes that can be accommodated on the deck is limited, and there will be hangars below the deck. Maintenance work must be done in the hangar. Aircraft are dispatched between the deck and the hangar. lift.

The principle of the elevator is similar to that of an elevator. It uses a motor to drive a steel cable, which pulls the car up or down. At the same time, for balance, a counterweight is hung on the other end of the cable. The outer walls of elevators in many shopping malls use Glass, you can clearly see the principle of this elevator.

Ordinary elevators are very reliable, but the structure is too complicated, so Ma Ming thought of an electromagnetic elevator.

Qin Tao did not propose this technology. After all, electromagnetic ejection and electromagnetic blocking are necessary. Before Qin Tao came to this world, things like elevators did not exist in China, so he did not propose them at all.

I just didn't expect that Ma Ming thought of it and made it.

"It's similar to the principle of electromagnetic catapult and electromagnetic blocking system." Ma Ming said: "Arrange linear motors at both ends of the elevator, and use the electromagnetic force provided by the linear motor to achieve ascent or descent. It does not have the complicated parts of ordinary elevators. , is very simple, usually does not require maintenance, and can work stably for a long time.”

The most complex electromagnetic ejection and electromagnetic blocking are all done. This electromagnetic elevator is actually just a transplant of these technologies, which is quite simple.One day, after Ma Ming suddenly thought of this project, he quickly made it.

However, when Ma Ming came to sell, he was unanimously rejected.

You have frozen the blueprint, but you still want to modify it?No, absolutely not!What if something goes wrong?
Ma Ming was in the stage of bumping into walls everywhere. When he saw Qin Tao coming, he was overjoyed and immediately ran to Qin Tao, hoping that Qin Tao would give him support. Who would have thought that Qin Tao would not support him, but Leader Wu was tempted.

At this time, after hearing Ma Ming's words, Wu Shengli looked at Qin Tao again: "Boss Qin, how do you feel?"

"This electromagnetic elevator does have technical reserves, but if it is directly used on our aircraft carrier, it would be a bit risky." Qin Tao said: "Ma Gong, why don't we wait until the next aircraft carrier? We can also do it here Test it out over a few years."

"Mr. Qin, you have said before that a steam catapult is like a steam train, and our electromagnetic catapult is like a maglev train. We are about to enter the 21st century, and we must use the most advanced technology." Ma Ming said: "Now, you actually retreated again? After so many years, the technology of the elevator should have improved. Our 002 aircraft carrier has already used a lot of advanced technology, so why not add more? Moreover, there is no need to modify the design drawing , as long as one line is pulled over, those hydraulic and motor-driven elevators should have been eliminated a long time ago!"

Ma Ming is looking forward to arming the 002 aircraft carrier with advanced technology. This is the most advanced aircraft carrier in China and the most advanced aircraft carrier in the world. It must have advanced technology!
Qin Tao's mind was also thinking rapidly.

That's right, domestic aircraft carriers have never used electromagnetic elevators, but the Yankees have used them. The Yankees' new generation of Ford-class aircraft carriers use a generation-leading technology. Among them, electromagnetic ejection and electromagnetic blocking frequently have problems, but the electromagnetic elevators I haven't heard much about malfunctions. This thing is the only mature product among the products developed by the Yankees.

Now, why don't you just agree?
No, any new technology is risky, if you use it rashly, what if there is a problem?
After all, electromagnetic ejection and electromagnetic interception have been tested in Huangdi Village for several years. Thousands of aircrafts have taken off and landed, and there has been no problem. This electromagnetic elevator has to be tested tens of thousands of times.

The lift of the carrier-based aircraft must not be equipped with an electromagnetic lift. It has to be tested, but there are not only carrier-based aircraft lifts on the aircraft carrier!

Most people will be attracted by the lift of the carrier-based aircraft. After all, it has appeared in many movies, especially American movies. The American soldiers standing on the elevator and rising together with the carrier-based aircraft are so eye-catching.

Another type of elevator seems to have fallen into obscurity by comparison: the ammunition elevator.

The aircraft carrier formation has powerful offensive capabilities. These offensive capabilities are realized through carrier-based aircraft. Carrier-based aircraft carry a large amount of ammunition. How do these ammunition come from?

The fighter planes in the hangar are only for maintenance. When bombs need to be attached, they may be attached easily. However, there are still those planes on the deck, how to attach bombs?

Ammunition can be transported with the lift of the carrier-based aircraft, but it is very wasteful. What if the carrier-based aircraft needs to be moved?
Therefore, there are also small ammunition elevators on the aircraft carrier. There are more of these. There are usually two or three elevators for carrier-based aircraft, but there are seven or eight ammunition elevators. Moreover, the ammunition is not handled at one time.

For safety, the ammunition is on the lower level of the aircraft carrier. It needs to be transported from the lower level to the middle level, and then from the middle level to the deck. The elevators have been staggered by a certain distance during these two transports, so as to avoid danger: in case one What about bombs falling from the sky and hitting the ammunition elevators directly?If the ammunition elevator is directly from the bottom ammunition store to the deck, wouldn't it be possible for the bomb to drop directly into the ammunition store?
"Ma Gong, I can understand your eagerness to build our 002 aircraft carrier into an advanced modern aircraft carrier, but we can't rush for success, we have to take our time." After Qin Tao finished speaking, he looked at Ma Ming wanted to retort, and continued: "However, your idea of ​​the electromagnetic elevator is good. I think we can replace one of the ammunition elevators on the aircraft carrier with an electromagnetic elevator, so we can test it first. If the navy uses it well, we can use it next time." All aircraft carriers can be equipped with electromagnetic elevators, what do you think, Leader Wu?"
