After hanging around Tianjiao Airlines for a long time, everyone left in the evening and took a car to the airport.

"Taozi, can that D18t engine really be developed into a 40-megawatt gas turbine?" Wu Shengli couldn't wait to discuss it with Qin Tao in the car.

"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."

At an ambient temperature of 15 degrees Celsius and an altitude of sea level, the L6000 gas turbine has a basic output of kilowatts and a thermal efficiency of more than 40%. At the same time, if you want to further increase the output power, you can add water to increase the power.

To kilowatts, the thermal efficiency is close to 50%.

The D18t of the same era can certainly reach this level. If it is improved with current technology, the power can be greatly increased. If the development of the L2500 gas turbine is followed, the final power can be doubled.

"If this kind of 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 20,000-ton destroyer and a 40,000-ton amphibious assault ship will all have power reserves." Qin Tao said: "So, even if this project will cost a huge amount of money, our Mingzhou Group will continue to carry out it firmly.

.”

Wu Shengli opened his mouth wide. If it were in the past, he would never have such a dream. Needless to say, a destroyer of 20,000 tons and 5,000 tons has been out of reach for a long time. As for

What is the difference between a 40,000-ton amphibious assault ship and an aircraft carrier?

"Taozi, in the past few years, you have been talking about amphibious assault ships. Will the combat missions of this thing and our aircraft carrier overlap?"

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.

Let’s talk.”

The Wasp class was developed to replace the old Iwo Jima-class amphibious assault ship with the Tarawa-class amphibious assault ship. During the design, it had many new concepts. For example, it was to operate Sea Harrier fighter jets.

As well as air-cushion landing craft, the area of ​​the garage deck and cargo deck in the hull has become smaller, just to load more Sea Harriers. In the later period, the Sea Harriers were replaced by 35b, and the combat effectiveness was further improved.

The first Wasp-class amphibious assault ship was built in the 1980s. When the eighth ship was built, it was already in 2002. This last ship also made some improvements, especially the use of gas turbines to replace the previous boilers.

, with its upgrading, the U.S. Navy completely abandoned the boiler.

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

"The emergence of the Wasp class has given the U.S. Marine Corps the ability to attack without approaching the beachhead. Through the Sea Harrier fighter jet, it can better control the beachhead position. Currently, we already have the J-31A, which is completely

It can be deployed on an amphibious assault ship, and we also have electromagnetic catapults. Adding an electromagnetic catapult to the amphibious assault ship can allow the fighter jets to eject and then land vertically. In this way, the performance of the fighter jets will be even more powerful.

Qin Tao said: "Even in some low-intensity conflicts, our amphibious assault ship can calm down the situation by driving over."

Wu Shengli nodded. Aircraft carriers are very important, but they are too expensive and there will not be 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, we just received news that the No. 1 and No. 2 cabins of the No. 002 aircraft carrier are about to be closed in the dock of our Mingzhou Group." At this moment, Zhao Ling spoke.

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

"What makes you so excited is that the two cabins are docking. Are you so impatient?" 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. Build one segment on the slipway and build another segment next to it. After both segments are built, they can be brought together and docked. In this way,

It can greatly speed up the construction progress.

At that time, in order to improve the construction progress of heavy-duty aircraft-carrying cruisers, Makarov proposed this concept and specially purchased overhead cranes from Western Europe for transportation.

Now, of course, Mingzhou Group is also using this arrangement.

Depending on the ship, the segments can be large or small. The best one is the British. When they built the Queen-class aircraft carrier, they only used four segments, one for the bow, one for the stern, and one in the middle.

Two sections were then started in different shipyards in England and Scotland. The advantage of this was of course that it greatly accelerated the construction progress. After the four sections were built, they were sent to a large shipyard in Scotland for consolidation. However, they

The reason why I dare to do this is because I bought a super gantry crane from the East, and after buying it, I sold it because no other ship needs such a big thing.

"How many sections?" Wu Shengli asked.

"Six sections. Even if we count another ship island, there are seven sections." Qin Tao replied: "The first section and the second section are starting to connect, which means that the third section will also need to be connected."

Construction has started, and it can be said that our aircraft carrier hull construction progress has reached one-third."

"Six sections?" Wu Shengli was extremely surprised: "How big must each section be!"

"That's indeed not small, but who knows how powerful our gantry crane is?" Qin Tao said with a smile.

The Queen-class aircraft carrier can be built in four sections. We used six, which is still too much. However, you have to eat in small bites and work in small steps, so don't be too anxious.

After all, it’s not yet the 21st century. If word spread about building an aircraft carrier in six sections, I don’t know how many people would be envious.

"I want to go 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 segment only has the bow deck, but the second segment begins to have angled decks.

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

Wu Shengli felt his breathing quicken. Even though 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.

There is no opening on the deck yet, so you can't see how the electromagnetic catapult is installed, but you can imagine in your mind what a spectacular scene it will be.

The motherland’s second aircraft carrier is comparable to the Kitty Hawk!

The segmented docking area reveals a dozen-layer structure. The upper one is very high and belongs to the hangar. The middle one is shorter and is the warehouse where the crew lives, eats, works, and stores food. Further down,

It will be higher and irregular. These are fuel, water, ammunition and other compartments.

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

With such a tall behemoth, what if there is an error during docking and the docking is uneven?

"Of course not." Makarov's voice sounded: "Leader Wu, twenty years ago, our warships built in sections could be perfectly connected, let alone now, every steel plate is bent using three-dimensional CNC.

When the board is made, the position of each weld is determined with a laser. Even if there is an error, the accuracy will be maintained below 01 mm. I am confident in our construction quality."

Looking at the docking cabins, Makarov was also filled with excitement. The once huge red empire had disappeared, and he once thought he was going to die in depression, but when he came to the east, he was reborn!

"Lao Ma, our construction progress is a bit slow." Qin Tao said: "It took so long to build 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 construction and sum up experience. The next construction will be faster. We are confident that each section will be completed

The segmented construction time is controlled within six months, so that in another two years, our hull construction will be completely completed and it can be launched into the water."

It took two years to launch the aircraft carrier, another two years for outfitting, and another two years for sea trials! Of course, according to the original plan, the aircraft carrier would be launched in the new millennium. Based on this calculation, it can still be slightly faster than the schedule. However, Qin Tao still

Feel dissatisfied.

"Slow, too slow. After launching, there is outfitting, and after outfitting, there are sea trials." Qin Tao shook his head: "However, this is the first time we have built an 80,000-ton aircraft carrier, so it is normal to be slow.

After experience, the next construction will be faster."

"Mr. Qin, during the segmented construction process, we have completed part of the outfitting work. For example, we have installed various internal pipelines, so the outfitting time can be saved a lot."

What?

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

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

Submarines are also built in sections, and during construction, they have to be outfitted. Once they are welded, various large parts cannot be stuffed in. Qin Tao did not expect that when his own side was building the aircraft carrier in sections, the outfitting work was also going on.

part of it.

"We have installed all the big parts in order to avoid having to cut holes later. When it comes to the subsequent construction of several sections, the power system and the like must also be installed in advance." Makarov continued: "So

, after it is launched into the water, the outfitting work should be completed within a year."

"Okay, our construction workers have all worked hard! The technicians have also worked hard. When the water is launched, everyone will get a big red envelope!"

"The docking is completed, all interfaces are correct, let's start welding now!" At this moment, Babbage shouted over there.

The two segments have been connected!

Relying on various advanced technologies, the two segments were constructed very accurately, ensuring a successful docking without any modifications. Now, welding can begin!

The first thing to be welded was of course the outside. On both sides of the sides, the two mechanical arms that had been prepared for a long time started to rotate flexibly. From the deck down, arc sparks came out.

In order to improve the progress, Mingzhou Shipyard has begun to use a large number of welding robots. When welding the ship hull, the robots play a major role. If it were not for these robotic arms to perform welding and only rely on manual labor, that segment would be

It would take easily one or two years to complete.

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

"Large sections of welds can be welded with welding robots. Only small sections, or those that are inconvenient for robotic arms, can be welded manually." Makarov said: "These machines are really good, and they are all made by our Mingzhou Group.

Developed, I think back then, if we had had this kind of equipment, we would have built a nuclear-powered aircraft carrier long ago."

When talking about the past, Makarov still has regrets.

This chapter is not over yet, please click on the next page to continue reading! "Don't worry, Old Ma, 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 twenty years."

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

"I really want to go up there and have a look." Wu Shengli was a little greedy. Seeing the two sections put together, one-third of the entire aircraft carrier came out. Wu Shengli really wanted to go up and take a look.

"Dad, you can't go up now. Construction is going on everywhere and it's very dangerous. Once the next few sections are closed and the aircraft carrier is launched, it won't be too late for you to go up and have a look."

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

"Mr. Qin, it's great that you are here!" At this moment, a man came over in a hurry. After seeing Qin Tao, he was very excited: "We have an idea for improvement here, but whether it is the aircraft carrier
To be continued...
