Chapter 258: Large through-deck bow ski-jump amphibious combat ship
When the sky in the east was slightly white, several IL-76 transport planes landed directly at the Huating Naval Aviation Airport. Countless vehicles that had been waiting here immediately started to move up. On the cargo platform at the rear of the cabin,
Bundles of design drawings were transferred to the car.
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 greeted them energetically.
"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. This is Leonid, an engineer in the Pacific Fleet's technical department."
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, while it's still dark, transport all these things over there as soon as possible. By the way, are you ready over there?"
"We have mobilized enough people and equipment overnight, and we will not waste time." Wu Shengli said, patting his chest.
Yesterday's dinner 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 saw that the sun 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 car after another, is this a convoy coming in?
Could it be that some more equipment has been shipped? 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 information. Decades later, those packages storing the information are still fresh in Yang Dawei's memory. 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 such a thing exist?
Yang Dawei hesitated for a moment, and then he recognized it. Among the people moving with him, there seemed to be Yang Zhaoxiang and Zhang Chao. Didn't they stay in Mingzhou? Why did they come here suddenly?
Yang Dawei walked up curiously, and then saw more people.
Some of my old colleagues from the design institute came, as well as some new faces I didn’t know, who looked like college students. These people were also the ones who worked the hardest.
Could it be that a new project is going to be launched here?
"Designers, please go to the conference room in the northeast corner for a meeting!" Someone began to convey the news.
Meeting?
A ladder conference room that can seat hundreds of people?
Suddenly a fire burned in Yang Dawei's heart. This must be some incredible big 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 confidentiality discipline. Although we all come from all over the world, we are all in related industries and know the confidentiality discipline. If anyone tells the truth about what is happening here, he will be waiting to 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, I will now solemnly announce to everyone that our Mingzhou Shipbuilding Industry Group's Second Design Institute 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!"
Earning two thousand yuan in less than a month is absolutely unprecedented. 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?
In particular, 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 Babbage. It was only decided a quarter of an hour ago. Anyway, the name is just a code name. Babbage doesn't care. Moreover, the name still has a certain meaning.
Mao, of course, means Lao Maozi, 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."
A large through-deck bow ski jump amphibious combat ship? Everyone was a little confused by this name, and some people reacted, Damn, isn't it an aircraft carrier? Is it so implicit?
Straight through the deck, the bow of the ship ski jumps to take off. 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 filled with ecstasy.
Do we need to talk about the modification of a 40,000-ton aircraft carrier? The answer is already obvious.
Mr. Qin, are you so awesome? You can get this kind of project? How did you bid with Lao Maozi?
Mr. Qin, we can do it even if we don’t pay. This is the most valuable experience!
Countless people got excited and roared with such energy that there was no need to mobilize at all!
"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 hard 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 results.
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 millions of dollars in consulting fees, targeting its 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 at it from 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 officially started.
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 several scanners running continuously day and night. No matter how many design drawings there are, how many college entrance examination papers can a province have? With several scanners running continuously, it can still be completed within the prescribed limit.
It was completed in a short period of time. (N years ago, when I went to East China Normal University, computer grading had just begun to become popular, and I was exposed to this thing. At that time, eye drops were given to every grading teacher, after all, it was still a CRT monitor)
The difficulty is not the scanning, but the conversion of the 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 purchased 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 a 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 modifications are needed, just make the changes directly, which is convenient and fast. If you still use the original manual drawing method, it will be an absolute dream to complete the project in half a month!
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.
Normal go-around!"
This chapter is not over yet, please click on the next page to continue reading! "I suggest that the rear deck can continue to 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." Babbage finally made the decision.
Yang Dawei's hands have begun to move quickly, operating 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.
"Selecting 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, we can have two 105-meter-long light-load take-off points, the one on the left is extended from the back, 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 the fighter aircraft. However, due to the distance from this point, the Su-33 can take off with a full load, giving full play to the advantages of the fighter aircraft.
There is no problem with this design for a 60,000 to 70,000 ton warship, but when placed 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 no problem, the MiG-29k is unknown, and the Su-33 is definitely not going to work.
This problem is simply unsolvable!
Babbage had a headache from this.
What about the counterweight, what about the middle part of the ship island, put all these aside, now 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 deviates to the left and misses 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, and it 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. But 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 an angled deck, so why not just use it anyway? In this way, although take-off and landing interfere with each other, they can take off directly with a heavy load!"
If the entire ship island is relocated, space can be made available, but it must not be done in a big way because the amount of modifications is too large.
Simple modification, it should look 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!"
Qin Tao said, and 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 interfere anyway, so let's just 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 to avoid any problems.
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."
Babbage is a person who pursues perfection, but now, it is not an original design, it is 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 now 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.
Babbage 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? Even if we design it, we won't be able to construct it."
Needless to say, there is no one with a 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 and twenty tons.
about there.
This ski jump deck is welded bit by bit in this way.
Side lift? That thing is extraordinary.
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 the 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 caught the arresting cable. Before it could stop, 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. 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 make changes. However, the design is fine, but the construction is difficult!
A big thing like a side lift can easily weigh hundreds of tons. How can it be installed without a crane? Moreover, during installation, it is necessary to open an opening on the side of the warship, and a crane is also needed to hoist the cut steel plate, otherwise it will fall directly.
The scaffolding needs to be smashed to the bottom.
Without this condition, how can we build a side lift?
Babbage 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 bad, not to mention that there are still 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, it was Ah San’s money that was earned this time, and Ah San didn’t know it yet!
Of course, the combat effectiveness of an aircraft carrier cannot be too strong, and good things like the Sky Sentinel Radar must of course be dismantled.
During the process of scanning and vectorizing the detailed drawings, a group of people were studying the overall modification plan. After the previous projects were completed, they immediately switched 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.
