Chapter 440 Discussion on aircraft carrier modification plan
Vitalia continued to stay in Ma Port, releasing smoke bombs. She wanted to stand on the last guard, while Qin Tao returned to Huating.
The Second Design Office of Mingzhou Group has been plunged into crazy work.
Those mountains of design drawings were placed in the warehouse of the design office, and countless computer operators proficient in Russian input them into the computer. The subsequent modification work will be carried out in the computer.
Among all the people, Babbage is undoubtedly the most excited one. The promise Qin Tao made to him has been fulfilled!
He came to the East to continue the aircraft carrier business. Now, the Varyag has been brought back by Qin Tao. As the chief construction engineer of this aircraft carrier, he can't wait to complete the warship.
Of course, he can't be anxious yet. After all, the warship is still on the way. Even if he goes to the Mingzhou Shipyard now, it doesn't make any sense.
When Qin Tao appeared at the design office, everyone was looking at Qin Tao with admiration, as if they were welcoming a returning king.
“Mr. Qin, you are so awesome!”
“Mr. Qin, you have done something earth-shattering!”
“Mr. Qin, you are my idol!”
Faced with these compliments, Qin Tao just smiled and waved his hands: "Hurry up and get to work!"
Inputting information into the computer is only the first step. The second step is to modify the aircraft carrier. This is the most critical.
Before revising, a rough plan should be determined.
"Mr. Qin, there is only an empty shell left in this warship, so we almost need to renovate it from scratch." In the office, Babbage said to Qin Tao: "From cables, ventilation ducts, to various equipment , all need to be replaced with new ones.”
“Yeah, I wouldn’t be worried if I still use the old one.”
Some of the cables inserted into the outfit were removed by the shipyard, and some were dismantled and sold by some shipwrights. If they are not all replaced with new ones, what if there is a short circuit inside?
Everything had to be replaced, and what they got was an empty shell, even more complicated than a new build because of the thorough cleaning.
However, this is also a necessary step.
“These are all details. Let’s talk about the important ones first, let’s start with the power system.”
Just when the two were about to discuss in detail, a voice came from outside: "Is this how you plan to discuss privately? Can we listen in?"
This is the voice of Wu Shengli.
Not only Wu Shengli, but also a large number of people came over. The gray-haired old man next to Wu Shengli surprised Qin Tao and he hurriedly greeted him.
“Mr. Liu, why are you here?”
"Of course I'm coming. I heard that you came back from Ma'ang, so I came from the capital. It seems that you young people are faster and got there one step earlier than me."
“Mr. Liu, you are so busy...”
"No matter how busy you are, you still come, Comrade Qin Tao, you have made great contributions to our navy! On behalf of the navy, I thank you!"
"These are what I should do. If the navy needs it, I can donate it to the navy."
Qin Tao was excited. He thought of the old man in front of him looking at the photo of the American aircraft carrier, and felt a little sad. From now on, there is no need to envy others, we have it ourselves!
Although he spent a lot of money, he made a lot of money in Ma Gang, and the money has not been spent yet. If he really wants to donate, Qin Tao will not frown.
"You have made great contributions to the country, how can you pay for it yourself?" Mr. Liu said: "We tighten our belts and have to raise this money for you."
"Taozi, just do your best." Wu Shengli said, and thought of something: "Let's not just stay here. Let's go to the conference room. You can continue the discussion while we listen."
The Second Design Office of Mingzhou Group is responsible for designing aircraft carriers and has rich experience. It has a modified Kiev aircraft carrier park, an aircraft carrier for the Siamese country, and an aircraft carrier designed for the Turkish country. Therefore, they deservedly took over. The design task of refitting the Oriental Sea Blocking City is an important task.
There was a lively atmosphere in the conference room.
"We went on to say that the first big problem is the power system. Relevant domestic departments have designed a special boiler that can burn 120 tons of high-pressure steam per hour. Moreover, the appearance is exactly the same as the originally designed TB-12, so "There are no technical obstacles in replacing the power system. Using eight boilers and four steam turbines, the warship can reach a speed of 30 knots."
“Do we still have this kind of power system in our country?” Mr. Liu asked curiously.
"Yes, when we got the Kiev from Lao Maozi, there were several good boilers in it, so we took them apart and copied them, and then made some improvements to target its weaknesses. It improved safety. It also increased the steam volume." Wu Shengli introduced it to Mr. Liu.
“Okay, Comrade Qin Tao made the arrangements in advance.” Mr. Liu said.
“I just don’t want good things to go to waste. These devices are mainly responsible for Wang Gong, and the refractory bricks inside were developed with the help of our university professors. They are the biggest contributors.” Qin Tao is very modest.
“Old Mao, continue.”
"In order to meet the power needs on warships, we also need specialized auxiliary power units. The auxiliary power units themselves include turbine generators, diesel generators, auxiliary condensers, desalination units, refrigerators and auxiliary boiler units." Babbage Continued introduction: "Let's talk about the generators first. We plan to use 9 turbine generators with a power of 1,500 kilowatts and 6 diesel generators with the same power. This will produce a total power of 22,500 dry watts to meet our power needs. Baidu is talking about a turbine generator. The East China Hero's understanding is that a steam turbine drives a generator, which is similar to a power plant.)
An aircraft carrier requires 22.5 megawatts for power supply alone, which is quite a lot. An aircraft carrier is equivalent to a city, which is definitely not a joke.
When he heard this, Qin Tao frowned, and then said: "We have too many generators, which will greatly increase the complexity of our use. I think it is better to use two main generators and two backup generators." A diesel generator will suffice.”
A large number of generators may sound like they can serve as a backup, but in actual use, the greater the number, the more problems will arise.
“Two main generators? If this is the case, the power of the generator must be greatly increased!” Babbage frowned: “I’m afraid we don’t have such a generator in China, right?”
"Yes." Qin Tao nodded: "The two main generators need to generate 10 megawatts of power alone. In this way, two units are 20 megawatts. Together with two diesel generators, each unit has a power of 3 megawatts. This way Two 6 MW units, total power 26 MW.”
Babbage frowned: "Mr. Qin, you said these data are simple, but it will be difficult to implement. I have never seen such a large marine generator system."
This cannot be blamed on Babbage. After all, Babbage is only responsible for developing aircraft carriers. He has not yet been involved in the power systems used by domestic submarines. Even though he will hold meetings in China at certain times, he has not had much contact with them.
“This project still requires the cooperation of horse workers.” Qin Tao said: “Currently he is designing a generator for our Mingzhou Group’s nuclear power plant, and the estimated power generation is 40 megawatts.”
“What? Is it a single generator?” Babbage was stunned.
Qin Tao nodded: "That's right."
Babic took a breath of air. A single generator has reached the 40-megawatt level? Isn’t this too awesome? The East actually has this kind of technology? Not even when their red empire was at its most powerful!
"If this is the case, then there will be no problem in designing a 10-megawatt turbine generator. We can arrange it according to this arrangement!" Babbage was very satisfied.
Qin Tao knew that Gong Zhao from Institute 704 was also outstanding in this aspect. He and Gong Zhao had worked closely together before time travel. However, after all, Gong Zhao started working in 1982 and started working slowly from the workshop. Therefore, it is estimated that it will be difficult to take the lead now.
Hence, the entire power supply project for warships has to be done by horse workers.
In the future, when Gong Zhao emerges, you can also go to him. A single turbine generator can reach a power of 20 megawatts, so two turbine generators will equal 40 megawatts. The power of electromagnetic ejection is enough.
Now, there is really no need for electromagnetic catapult. After all, electromagnetic catapult cannot be launched all at once. This half-baked aircraft carrier probably has no chance to enjoy the elegance of electromagnetic catapult. However, space can be reserved in case of modification in the future. demand.
“If this is the case, our warship has the strongest power generation capability among conventional power sources,” Babbage said.
Among conventionally powered aircraft carriers, the Kuznetsov is the same as the Babbage plan, with a power generation capacity of 22.5 megawatts, far exceeding the Kitty Hawk.
The Kitty Hawk class is equipped with eight 1.5-MW steam generators, two 0.75-MW diesel generators, and three 1-MW diesel generators, with a total power generation capacity of 16.5 MW.
The Nimitz-class aircraft carrier is equipped with eight 8-megawatt steam generators and four 2-megawatt diesel generators, with a power generation capacity of 72 megawatts (some say it is halved to 36 megawatts). I feel that this number is more reliable. letter.).
As for the Gallic Charles de Gaulle, it is equipped with four 4-megawatt steam generators, four 0.25-megawatt gas turbine generators, and four 0.8-megawatt diesel generators, with a power generation capacity of 19.2 megawatts. (There are so many)
Now, the plan proposed by Qin Tao will reach 26 megawatts of power generation, which is not as good as nuclear-powered aircraft carriers, but it is definitely the first among conventionally powered aircraft carriers.
Babbage nodded and continued: "Let's move on to other subsystems, the most important of which is the air-conditioning system. In order to regulate the air for the entire warship, we need to install 5 turbo-compressor Freon refrigeration machines. The refrigeration efficiency is 2 million kilocalories per hour respectively.”
Qin Tao has no objections to these.
Mr. Liu has been listening by the side with longing in his eyes.
Having finished talking about the power system, we then slowly talked about the layout under the front deck from the back to the front.
"Under the front deck, there is an anti-ship missile launcher. In the Red Empire era, this kind of device was the mainstream, but now, we can only give up." Babbage said: "However, this is the original design after all, so if we It would be a bit dangerous to open it up to expand the hangar area."
Babiqi has a headache here.
In the original design, this was used as an anti-ship missile launching mechanism. The 12 powerful shipwreck anti-ship missiles were a terrible blow to the enemy's aircraft carrier formation in one wave.
After all, if you want to break through the protective circle of the enemy's aircraft carrier formation, you have to carry out a saturation attack. There have to be many batches, and this is just one of them.
After the collapse of the Red Empire, the last Kuznetsov was taken away by Mao. There must be anti-ship missiles in it. In order to prevent military secrets from being leaked, Mao will never allow the export of relevant technologies to Eastern.
Now, this place is empty.
Although there are anti-ship missiles in China, they are not suitable to be placed here. After all, they are too small and not of the same order of magnitude.
"How about turning this place into a canteen?" Qin Tao said: "Anyway, this semi-finished product is just a seed for our motherland's navy aircraft carrier. It is more suitable as a navy aircraft carrier training ship. We have to build the real aircraft carrier ourselves."
commissary?
Wu Shengli was almost so shocked by Qin Tao's words that his eyes fell down. Boy, are you serious about saying this? What canteen?
There are no commercial establishments on navy warships. After going to sea, you can eat, drink, and have **** on the warship without spending any money. Qin Tao actually wants a canteen, which is a bit excessive.
“Is it a supermarket affiliated to Mingzhou Group?” Another leader said with a smile.
“If the Navy is willing, we can contract it.”
"The navy has stopped doing business a long time ago!" Wu Shengli finally couldn't help it anymore and was extremely dissatisfied with Qin Tao's joking attitude. But then, he thought of something else: "Taozi, when we were designing nuclear submarines, you weren't Is there an anti-ship missile launch bay reserved for our nuclear submarine?"
Anti-ship ballistic missile?
When he heard this sentence, Qin Tao also saw a car in front of him.
That’s right, how could you have forgotten this?
We don’t have Lao Maozi’s anti-ship cruise missiles, but we do have big ballistic missiles!
In terms of size, the diameter of the P-700 missile is 0.8 meters, and the diameter of the launch tube is larger. Therefore, it is absolutely no problem to stuff your own 850 mm launch tube into it. The length of ten meters is almost enough. used.
In this way, our own aircraft carrier can launch anti-ship ballistic missiles?
"You have anti-ship ballistic missiles?" Babbage was also shocked. This kind of thing existed in Lao Maozi's era, but was abandoned later. Unexpectedly, it was actually developed in the East?
"Relevant units are currently studying it." Qin Tao said: "It seems that it is possible to install it, so this device will be kept for now. When our small anti-ship ballistic missiles mature in the future, they can be inserted into it. Once If there is a situation, just test-fire one to scare those **** to death."
Qin Tao's words made everyone laugh.
“Mr. Qin, you don’t want to open a canteen anymore?”
“Well, I won’t open a canteen anymore, and I’ll send express delivery instead.”
"express delivery?"
It was only 1995, and online shopping had not yet taken off in China. People only knew how to send things by post, and they didn’t quite understand the meaning of express delivery.
“That’s right, Dongfeng Express must achieve its mission. You will know it later, let’s continue.”
The current anti-ship ballistic missile was developed on the basis of Dongfeng 21. It is too large, with a diameter of 1.4 meters, and is destined to be unable to be carried on ordinary warships. Therefore, everything needs to wait until a new missile with reduced size is released in the future. After that, it can be stuffed in.
So now, it can only be reserved.
In any case, it doesn’t matter if you have a canteen or not. With a rich life, you have to continue working even if you don’t have one.
Having finished talking about what’s on the lower deck, it’s time to talk about what’s above.
The deck comes first. There is nothing to say about this. The layout hardly needs any adjustments or changes and remains as it is.
"There are two take-off lines and three take-off points on the deck. The taxiing length of the No. 1 and No. 2 close points is 105 meters. The No. 3 take-off point is behind the No. 2 take-off point, and the distance increases to 195 meters. According to Kuz The test on the Nezov showed that it had a take-off capacity of 29 tons and 32.8 tons respectively. Since the warship's upturned angle reached 14 tons, it is impossible to achieve a maximum take-off capacity of 33 tons when the aircraft carrier is sailing at full speed. Any questions.”
Speaking of ski jump takeoff, a very popular saying is that it cannot take off with a full load and cannot take advantage of the load capacity of the Su-33 fighter jet. This statement is inappropriate. In 1989, Lao Maozi was on board the Kuznetsov A large number of take-off experiments have been done on the warship. When the warship is sailing at full speed, the 32.8-ton Su-33 has absolutely safe take-off capabilities. The flying speed reached 185 knots and the altitude was 38 meters. Taking advantage of the angle of the ski jump, it continued to climb upwards. It could continue to accelerate to a recovery speed of 328 knots without losing any height, and then perform various maneuvers.
Even the crazy old Maozi tested a takeoff with a weight of 38 tons at a far point of 195 meters. After flying out, the trajectory became an reverse S shape, but he could still recover smoothly, so it became the maximum takeoff weight.
Saying that it cannot take off with a heavy load is a layman's term. However, there is another shortcoming of ski jump takeoff that cannot be concealed: low deck utilization and low aircraft dispatch efficiency.
Compared with the whooshing ejection of a catapult, ski jump takeoff is too slow, especially when taking off from a far point, and it will interfere with operations in the landing zone.
Therefore, catapult take-off is definitely a trend, especially electromagnetic catapult, which does not consume precious water vapor and does not freeze on the deck. After continuous ejection, the speed of American aircraft carriers will continue to decrease because there is not enough steam. Take a break and work harder.
As for now, let’s resolve the issue of availability first, efficiency and the like are matters for the future.
“Lastly, there is the ship island.” After talking about the deck, Babbage continued to talk about the layout of the ship island.
"According to the original plan, a four-sided phased array Sky Sentinel radar needs to be installed on the ship island." Babbage continued: "But after arriving here, I think it may need to be modified. There is a mature meter wave long-range warning here. The radar, combined with our top-plate radar, can meet the scanning needs of the surrounding airspace."
“No, we want to install a four-sided phased array. Since this space has been reserved, of course it cannot be wasted.” Qin Tao said.
“Install a four-sided phased array radar? Where to purchase it?” Babbage was a little surprised.
At present, there are no four-sided phased array radars seen on Eastern warships. The only air defense destroyers in service use radars modified from the S-300 system on land. Even if this device is installed on four sides , those are only four systems and will not be combined.
In fact, even the Sky Sentinel radar does not perfectly solve the problem of system combination, which requires powerful computer processing capabilities.
"Of course it is our relevant domestic institutions. The active phased array radar they developed is undergoing testing." Qin Tao introduced: "Put it on our warships. It does not need to guide anti-aircraft missiles. It is just used to scan the surrounding space. It should be able to It's simpler. By the time our aircraft carrier is repaired to the bridge, the phased array radar should be able to meet the construction deadline."
Active phased array radar?
Babic opened his eyes again: "You actually have a ship-based active phased array radar? This is probably the first in the world!"
Americans have the most mature technology and have built a large number of Aegis warships. However, these warships use passive phased array radars. Active phased array radars on fighter aircraft are also under development.
As for Lao Maozi’s Sky Sentinel, there is no doubt that it is a passive phased array. There is no active phased array radar in the world that has been installed on a warship. Now, will this ship I own become the first?
“Yes, it should be the first in the world.” Qin Tao said: “Only active phased array radar can meet a large number of target search needs. Whether it is an aircraft or a missile, it must be discovered immediately.”
American aircraft carriers do not have four-sided phased array radars, but ordinary parabolic antenna radars. That is because the U.S. Navy has a large number of Aegis warships, and the **** mission can be completed smoothly.
The aircraft carrier only needs to be used as a take-off platform for carrier-based aircraft, which is enough.
Other countries do not have this advantage. Lao Maozi uses a four-sided phased array in order to better increase the detection capabilities of the surrounding airspace. Our own aircraft carriers are of course no exception.
"Using a four-sided phased array radar, we can complete uninterrupted tracking of a large number of targets and determine threats. At the same time, it can also be integrated into the command system of our warships." Qin Tao said: "Of course, other related There is also a lot of equipment that requires the assistance of our relevant departments. When we design, we can reserve it first. After all, if we modify it, we will start from the bottom first."
Babic nodded.
Electronic equipment is developing too fast. Now their designs may not necessarily determine all the electronic systems directly, and they can be modified at any time in the future.
