Chapter 259 Large through-deck bow ski-jump amphibious combat ship

When the sky in the east turned slightly white, several IL-76 transport planes landed directly at the Huating Naval Aviation Airport. Countless vehicles that had been waiting here immediately started moving up. On the cargo platform at the rear of the cabin, bundles of design drawings were transferred to the vehicles.

Because of the continuous coordination and not much rest, Wu Shengli's eyes were bloodshot. However, when he saw several people getting off the plane, he immediately went up to them in high spirits.

"came back?"

"Well, I'm back." Qin Tao yawned. Although he slept on the plane, he still felt uneasy, so he didn't have a good rest along the way. There was a tough battle to fight next, and he had to arrange his work first. Just go down.

“Dad, let me introduce you, this is Zaitsev, my good friend over there, and this is Leonid, an engineer in the technical department of the Pacific Fleet.”

Qin Tao introduced the people he brought to Wu Shengli. Since these old men were here, it was not convenient for Wu Shengli to say anything. He stretched out his hand: "Welcome, please rest assured, these design drawings There will definitely be no problems, and after you use it, it will be returned to you intact."

Leonid nodded: "Now, before it's fully light, transport all these things over there as soon as possible. By the way, are they ready over there?"

"We have mobilized enough people and equipment overnight, and we will not waste time." Wu Shengli said, patting his chest.

The dinner yesterday was very enjoyable, and many people drank too much. So, when Yang Dawei opened his eyes in the early morning, he still felt a little headache. He glanced at the window, and the sunlight was already shining in. It was time for him to get up.

Yang Dawei sat up and went to the bathroom to wash his face. As soon as he woke up, he was startled by the sound of cars outside.

 One vehicle after another. Is this a convoy coming in?

 Did any more equipment arrive? It shouldn’t be! All the equipment has been purchased and installed in place!

With doubts, Yang Dawei got up and walked forward from the dormitory area. Then, he saw trucks unloading their goods. He was stunned for a moment.

 Looking at the shape of the package, it is clearly a drawing!

When designing the 051 destroyer, we referred to the design of Lao Maozi's Colin-class destroyer. At that time, we obtained some of Lao Maozi's design data. Decades later, Yang Dawei still remembers those packages containing the data. That year When he first went to the Ship Design Institute, he had taken care of the warehouse and knew this thing very well.

 Now, how could there be such a thing?

Yang Dawei hesitated for a moment, and then recognized it. Among the people moving with him, there seemed to be Yang Zhaoxiang and Zhang Chao? Aren’t they staying in Mingzhou? Why did you come here suddenly?

Yang Dawei walked up curiously, and then saw more people.

Some old friends who were in the design institute are here, as well as some new faces that I don’t know. They look like college students. These people are also the most energetic.

  Could it be that a new project is about to be launched here?

“Designers, please go to the conference room in the northeast corner for a meeting!” Someone began to convey the news.

 Having a meeting?

 A ladder conference room that can seat hundreds of people?

Yang Dawei suddenly felt a fire burning in his heart. This must be some kind of huge task!

By the time he entered, the conference room was already filled with people, at least hundreds of people.

Babic was sitting on the rostrum with an excited face. On his left were Qin Tao and Mr. Pan, and on his right were several old men.

“Okay, everyone is almost here.” Qin Tao started to speak, and everyone immediately became quiet.

"First of all, please pay attention to the discipline of confidentiality. Although we all come from all over the world, we are all in related industries and know the discipline of confidentiality. If anyone tells the truth about what is happening here, he will spend the rest of his life in prison! If you feel that you have not kept the door open, you can leave now, but after the meeting, there will be no turning back, and you will spend a completely closed month here."

  Qin Tao's words were not meant to scare people. This battle was definitely unusual.

“Okay, since everyone hasn’t left yet, I would like to solemnly announce to you that the Second Design Institute of Mingzhou Shipbuilding Industry Group has now been established!”

There was a round of applause below.

"After we were established, we faced a challenge. I gave everyone a task. We need to complete the scanning and vectorization of the original drawings within one week, and complete the improved design within two weeks. The time is tight and the tasks are heavy, so everyone may have to work hard next, but as long as the project is completed, everyone will get a salary and bonus of 2,000 yuan!"

 It is absolutely unprecedented to make two thousand yuan in less than a month. However, the people present are not excited about money. At this time, they are all paying attention to this design task.

 What is the task that requires the cooperation of these people?

Especially, what does the old man on the rostrum do?

“First of all, let me introduce to you, Mao Gengxin, the director of our design institute and the general person in charge of this project.”

Qin Tao said, pointing his hand at Babic beside him.

What? Mao update?

Mao Gengxin, of course, is the new name Qin Tao gave Babic. It was only decided a quarter of an hour ago. Anyway, the name is just a code name. Babic does not matter. Moreover, the name still has a certain meaning.

Mao, of course, is what Lao Maozi means. Renewal means coming here and starting a normal life. Everything is renewed.

The people below applauded in unison. Of course they knew that this name was a code name, and from now on they would be called Director Mao. What they cared about was their mission!

"Director Mao has a lot of experience in ship manufacturing, especially in the 40,000-ton large through-deck bow ski jump amphibious combat ship, which will play an important role in our modification project. Therefore, everyone must cooperate with him and cooperate with him wholeheartedly.”

 Large through-deck bow ski-jump amphibious combat ship? Everyone was a little confused by this title, and some people reacted, Damn, isn't it an aircraft carrier? Do you need to put it so implicitly?

Straight access to the deck and ski-jump takeoff from the bow. Isn’t this the design plan of Lao Maozi’s third-generation aircraft carrier?

 Mr. Qin, can't you be more straightforward?

Although everyone complained a little, after reacting, their faces were full of ecstasy.

 40,000-ton aircraft carrier modification, needless to say? The answer is already there.

 Mr. Qin, are you too awesome? Can such a project be obtained? How did you bid for Lao Maozi?

 Mr. Qin, we can do it even if we don’t pay. This is the most valuable experience!

Countless people are excited, and there is no need to mobilize that roaring energy!

“To make it simpler, we call this project Project 2001, and everyone will use this code name in the future.” Qin Tao also felt that the series of words was too difficult to pronounce, so he simply gave it a code name.

 2 represents the second design office, and 001 represents the first project of the design office.

Some of these people in front of me will leave after the project is completed, and a group of people will stay and continue to work. However, whether they leave or stay, the 2001 Project will leave an indelible impression in their hearts and become a Their most unforgettable memories.

For them, this is the most rare experience. Among these people, some have participated in the 707 Project and some are currently working on the 891 Project. However, they will never have access to such detailed information, let alone such an opportunity. Design it with your own hands, and it may eventually become a reality!

At that time, Project 707 was launched, and the Navy planned to develop a 30,000-ton light aircraft carrier. However, it was very poor and had nothing. The most important information was a pieced together "U.S. Imperial and Soviet Repair Aircraft Carrier Atlas" ".

The foundation of Project 891 is higher. After all, the Melbourne has been dismantled and there is more information. This project plans a 50,000-ton aircraft carrier plan, steam power, steam catapult, etc., and there will eventually be more than 100 Reports, millions of words of research.

 However, that was also done behind closed doors. How could I have access to all the information about Lao Maozi's heavy-duty aircraft carrier cruiser like now?

Qin Tao knew that China had put in too much hard work to build aircraft carriers. In 1995, it even paid a Spanish company several million dollars in consulting fees, targeting the other party's 25,000-ton SAC-220. Aircraft carrier design drawings.

Now, after this project, everyone will have the first opportunity to practice the design of aircraft carriers, which will lay a solid foundation for the future production of aircraft carriers in the motherland!

Thinking of this, Qin Tao's heart surged.

 “Cough, cough.” Someone next to him coughed.

Qin Tao glanced out of the corner of his eye and realized what he was doing.

"Let me introduce to you again. This Mr. Wang Ming is responsible for our confidentiality work. Everyone must abide by the confidentiality discipline. No information is allowed to be taken away. After the project is completed, it will be destroyed according to Mr. Wang Ming's arrangement. We We are only responsible for the design process and we will not leave any data behind. This is the principle.”

Wang Ming, a simple name, is Leonid’s pseudonym.

Leonid stood up and muttered something to the effect that if you didn't follow what he said, you would be thrown into Siberia. However, the translator skillfully translated his words to make the scene seem more friendly. .

 After the meeting, the project was officially launched.

 The paper design drawings were unpacked one by one, stuffed into the scanner, entered into the computer, and then repackaged into their original form and put back again.

Although there are many design drawings of the aircraft carrier, it can still be completed with a few scanners running continuously throughout the day and night. No matter how many design drawings there are, how many college entrance examination papers can a province have? Several scanners rotate continuously and can still be completed within the specified time. (N years ago, when I was a student at East China Normal University, computer grading had just begun to become popular, and I came into contact with this thing. At that time, every grading teacher was given eye drops. After all, it was still a CRT monitor)

 The difficulty is not the scanning, but the conversion of graphics.

When the design drawing is scanned in, it is a drawing, or a picture. This picture cannot be designed directly on the computer, nor can it be improved. This requires converting the graphics into vector graphics, and every line in it needs to be movable. OK.

This requires the server bought at a high price to operate at full power. After all, its computing power is almost half of that of the Galaxy 2 supercomputer.

 After the scanned drawings are converted into vector drawings, they still need to be sorted and archived. Currently, a large number of technical personnel are doing this work.

They were extremely excited as they watched the drawings come out one after another. This was the first time they had come into contact with such valuable information. They also tried to remember these design drawings and use them later.

“Thanks to the national call last year to get rid of the drawing board, if we had not adapted to computer graphics in advance, then we might not have the chance to participate in this kind of project!”

“Yes, there are several old comrades in our unit who have excellent drawing skills. Unfortunately, they are not able to learn computer drawing and have retired early.”

“Without computer graphics, it would be impossible to complete the changes in half a month.”

 After one year of popularization, key units have begun to engage in computer graphics. They have also begun to adapt to computer graphics and are aware of the advancement of this kind of graphics.

 When you need to make modifications, you only need to make changes directly, which is convenient and fast. If you still use the original manual drawing method, completing the project in half a month will be an absolute dream!

 In the conference room next to the office, a group of people have already entered the detailed research stage.

Babbage stood in front of the projection screen, holding a TV whip antenna in his hand, pointing to the graphic above: "The area of ​​the angled deck must be expanded to ensure that the carrier-based aircraft can survive the landing failure. Go around normally!"

“I suggest that the rear deck can be extended back three to five meters.” Qin Tao added: “This can also balance the increased weight in the front.”

“Three meters, not too much, otherwise the hull structure will not be strong enough to support it.” Babic finally made the decision.

Yang Dawei's hands have begun to move quickly to manipulate the design drawings on the laptop. As a result, the rear deck on the projection screen increases at a speed visible to the naked eye.

Mr. Pan just watched and did not speak. For him, it was important to participate. Almost the entire idea was discussed by Babbage and Qin Tao.

 When doing business, Qin Tao was extremely smooth, but now, he is serious and has changed from a profiteer to an engineer.

“The choice of the take-off line is still the most difficult. Since the ship island directly blocks the take-off line, we can only make a ninety-meter-long take-off line at most, which cannot meet the take-off requirements at all!”

 The biggest headache for Babbage was taking off.

According to the design plan of Kuznetsov and Varyag, they will set up two take-off lines on the bow ski jump deck. The one on the right can directly reach the front of the ship island, and the one on the left can You can also continue to extend it backwards.

 In this way, you can have two 105-meter-long light-load take-off points, the one on the left is extended from the rear, and there is a 195-meter-long No. 3 long-range take-off point.

This take-off point has to fly over the angled deck area, which will cause obstacles to the recovery of fighter aircraft. However, due to the distance from this point, the Su-33 can take off with a full load and take advantage of the fighter aircraft.

 For a warship of 60,000 to 70,000 tons, there is no problem with this design, but when it is put on a 40,000-ton aircraft carrier, problems arise.

The ship island cannot be moved, and the jump deck in front cannot be too long. As a result, the runway for carrier-based aircraft to take off is not enough!

 Ninety meters, what can fly? The Sea Harrier is fine, the MiG-29K doesn’t know, but the Su-33 definitely won’t work.

 This problem is simply unsolvable!

 Babich had a headache from this.

 Things like counterweights and the middle part of the island, put these aside. At present, we can’t even solve the problem of taking off!

"What's so difficult about this? We just need to move the take-off line to the left." Qin Tao picked up another whip antenna and pointed at it: "Starting from the bow of the ship, the take-off line is deflected to the left. If you miss it, On the ship island, continue to the left, and you can set up a take-off point in the middle of the ship island. In this way, it is almost 160 meters, which is directly the heavy-load take-off point."

“However, this will interfere with the landing operation of the carrier-based aircraft!” Babbage immediately denied it.

At least we have to find one that won’t interfere with the landing operation. Otherwise, what’s the point of the angled deck?

When the British invented the angled deck, they wanted to prevent the landing and takeoff of carrier-based aircraft from affecting each other, making deck scheduling easier. Now, on a modified aircraft carrier, there is an angled deck, but it doesn't work. ?

"It doesn't matter, Asan has long been used to it." Qin Tao said: "Their previous aircraft carriers did not have angled decks, so why not just use them anyway? In this way, although takeoff and landing interfere with each other, they can directly take off with a heavy load!"

If the entire ship island is moved, it can make room, but it must not be done in a big way, because the amount of modifications is too large.

 Simple modification, it should be like this now.

"Then, we will set up a further take-off point on the left side of it, and attach another piece to the left side of the deck. In this way, we can create a 180-meter take-off line. Use the two lines together to improve the dispatch efficiency. Absolutely high, and they all take off with a heavy load!"

As Qin Tao spoke, he began to point to the enlarged port side area of ​​the deck, a protruding piece. Looking at the shape, it was really nondescript, but the 180-meter take-off line was also very necessary for carrier-based aircraft.

“It will cause interference anyway, so we might as well design it like this.” Qin Tao said: “Two planes take off together, the efficiency is very good, and the one that lands, just wait for a while.”

The take-off line must be arranged. After all, this is not a matter of directly drawing a line. Behind the take-off point, a hydraulically driven flame baffle must be set up. The flame baffle will open on the deck and reduce the strength of the deck. Therefore, related The parts need to be strengthened.

 It must be designed in advance and no problems can occur.

Yang Dawei quickly changed it according to Qin Tao's idea. Babbage looked at it for a long time and finally nodded: "Okay, your plan is a necessary compromise. Qin, there is no problem with your design, so just follow it Come here."

 Babich is a person who pursues perfection, but now, it is not the original design, but just a modification, limited by objective original conditions, this kind of compromise is necessary.

Although it looks nondescript.

"Okay, let's talk about the elevators next." Babbage said: "In order to facilitate the deck operations of the aircraft carrier, side elevators are currently used. Since our aircraft carrier is going to be modified, it should also have a side elevator. ."

“Do the shipyards in the Far East have a thousand-ton crane?” Qin Tao asked.

　　Babic frowned and thought for a moment: "No."

Just kidding, the Soviets cannot produce cranes of that level and can only outsource them. In order to let the Black Sea Shipyard build aircraft carriers, they gritted their teeth and bought two from Western Europe. Other shipyards simply did not have this capability.

“Since it doesn’t exist, what else should we design? Once the design is completed, we won’t be able to construct it.”

Needless to say one thousand tons, there are no two hundred tons. Lao Maozi renovated the aircraft carrier. There is no such a big dock, so he dug a hole directly by the river and stranded it. The only thing that started construction was a truck crane, which could lift ten tons or twenty tons. about there.

This ski jump deck is welded bit by bit in this way.

 Side lift? That thing is not ordinary.

The aircraft carrier has a hangar on the lower level and a runway on the upper level. Therefore, to transport aircraft from the lower level to the upper level, an elevator is needed.

In the past, a hole was made on the deck to lift the aircraft up. This is an inboard elevator. The Kiev-class is designed like this, and there is no problem. It is a vertical take-off and landing anyway, but it was modified into a short take-off and arrested landing scheme. Yes, there are requirements for the deck.

The plane was landing, and it also caught the blocking rope. Before it stopped, a big pit appeared in front of it. With a pop, it fell down to the lower hangar, followed by a raging fire.

 During the Cold War, side lifts became popular during the Cold War. They opened a hole in the side and lifted directly. The deck was still intact, and take-off and landing were not affected.

Babbage, who pursues perfection, needs to be modified. However, the design is fine, but the construction is difficult!

 A big thing like a side lift can easily weigh several hundred tons. How can it be installed without a crane? Moreover, during installation, openings need to be made on the side of the warship, and a crane is required to hoist the cut steel plates, otherwise they will fall directly and the scaffolding will have to be smashed to the bottom.

 Without this condition, how can we build a side lift?

 Babic could only give up.

“Let’s continue to look at the ship island. The Sky Sentinel radar is too bulky and must be dismantled.” Qin Tao continued to suggest.

Now Qin Tao is enjoying it. Even if he doesn't make money, designing an aircraft carrier of this level is not a bad experience, not to mention that he still has three million. Even if he has to wait until Asan is satisfied with the design, Nikola Only then would he give Qin Tao money, and Qin Tao didn't care.

 In short, the money earned this time is Ah San’s money, and Ah San doesn’t know it yet!

Of course, the combat effectiveness of the aircraft carrier cannot be too strong, and a good thing like the Sky Sentinel Radar must of course be dismantled.

In the process of scanning and vectorizing detailed drawings, a group of people are studying the overall modification plan. After the previous projects are completed, they will immediately switch to detailed design.

 In the computer room, the temperature suddenly increased. Qin Tao quickly asked someone to install the air conditioner, and everyone worked on the design day and night.

 Time is passing day by day.
