Chapter 440 Discussion on aircraft carrier modification plan

  Vitalia continued to stay in Magang, releasing smoke bombs. She had to stand on the last shift, and Qin Tao returned to Huating.

  Mingzhou Group's second design office has fallen into crazy work.

  Those mountain-like design drawings were placed in the warehouse of the design office, and countless computer operators who were proficient in Russian would input them into the computer, and the next modification work would be carried out on the computer.

  Among all the people, Babbage was undoubtedly the most excited one. The promise Qin Tao made to him was 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 engineer of the aircraft carrier, he can't wait to finish the warship.

  Of course, don’t worry yet, after all, the warship is still on the way, even if he goes to Mingzhou Shipyard now, it doesn’t make any sense.

  When Qin Tao appeared in the design office, everyone was looking at Qin Tao with admiration, as if welcoming a returning king.

   "Boss Qin, you are amazing!"

   "President Qin, you have done an earth-shattering event!"

   "President Qin, you are my idol!"

   Facing these compliments, Qin Tao just smiled and waved his hands: "Hurry up and work!"

  Entering into the computer is only the first step, and the second step is to modify the aircraft carrier. This is the most critical.

   Before modifying, a rough plan must be determined first.

"President Qin, there is only an empty shell left on this warship, so we almost need to renovate from scratch." In the office, Babiqi said to Qin Tao: "From cables, ventilation pipes, to various equipment , all need to be replaced with new ones.”

   "Yeah, if I still use the old one, I won't worry about it."

  Some of the cables stuffed into the outfitting were dismantled by the shipyard, and some were disassembled and sold by some boatmen. If not all of them are replaced with new ones, what if there is a short circuit inside?

  Everything had to be replaced, and all they got was a shell, even more complicated than a new build, because it had to be completely cleaned.

  However, this is also a necessary step.

   "These are details, let's talk about the important ones first, let's talk about the power system."

   Just when the two were about to discuss in detail, a voice came from outside: "Are you planning to discuss privately like this? Can we listen in?"

   This is Wu Shengli's voice.

   Not only Wu Shengli, but also a large number of people came together. The gray-haired old man next to Wu Shengli surprised Qin Tao, and hurried to greet him.

   "Old Liu, why are you here?"

   "Of course I'm coming. I heard that you came back from Magang, so I came from the capital. It seems that you young people are faster and arrived one step earlier than me."

   "Old Liu, you are so busy..."

   "No matter how busy you are, you will come, Comrade Qin Tao, you have made great contributions to our navy! On behalf of the navy, I thank you!"

   "These are all things I should do. If the navy needs it, it can be donated to the navy."

  Qin Tao was excited. He thought of the photo of the old man looking at the American aircraft carrier, and he felt a little sad. From now on, don't envy others, we have it ourselves!

  Although he spent a lot of money, he spent a lot of money in Magang Pengci, and the money has not been spent yet. If he really wanted to donate, Qin Tao would not frown.

   "You have made great contributions to the country, how can you pay for it yourself." Liu Lao said: "Let's tighten our belts, and we have to scrape together the money for you."

   "Taozi, you should work hard." Wu Shengli said, thinking of something: "Let's stop standing here, let's go, let's go to the conference room, you continue to discuss, let's listen."

The second design office of Mingzhou Group is designed for aircraft carriers, and has rich experience. There is a modified Kiev aircraft carrier park, an aircraft carrier for Siam, and an aircraft carrier designed for Tuji. Therefore, they deservedly took over The design task of refitting the Dongfang Maritime Blockade.

  In the conference room, there was a lively atmosphere.

"We went on to say, first of all, the first big problem is the power system. The relevant domestic departments have designed a special boiler that can burn 120 tons of high-pressure steam an hour. Moreover, the shape is exactly the same as the originally designed TB-12, so , There is no technical obstacle in changing the power system, with eight boilers driving four steam turbines, the warship can reach a speed of 30 knots."

   "Does this kind of power system exist in our country?" Elder Liu asked curiously.

"Yes, when we got the Kiev from Lao Maozi, there were a few good boilers in it, so we disassembled them for imitation, and then made some improvements to address its weaknesses. Improved safety, It also increased the amount of steam." Wu Shengli introduced to Mr. Liu.

   "Okay, Comrade Qin Tao made the arrangements in advance." Liu Lao said.

   "I just don't want good things to go to waste. These devices are mainly in charge of 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 humble.

   "Old Mao, continue."

"In order to meet the power needs of the warship, we also need a special auxiliary power unit. The auxiliary power unit itself includes a turbo generator set, a diesel generator, an auxiliary condenser, a seawater desalination unit, a refrigerator and an auxiliary boiler unit." Babich Continue to introduce: "Let's talk about generators first. We plan to use 9 turbine generators with a power of 1,500 kilowatts and 6 diesel generators with the same power. In this way, a total power of 22,500 kilowatts can be generated to meet our power needs. Baidu came to talk about turbine generators. The understanding of the hero of East China should be that the steam turbine drives the generator, which is similar to that of a power plant.)

  On an aircraft carrier, just power supply requires 22.5 megawatts, which is quite a lot. An aircraft carrier is equivalent to a city, and it is definitely not a joke.

Qin Tao frowned when he heard this, and then said: "We have too many generators, which will greatly increase the complexity of our use. I think that using two main generators and two backup ones A diesel generator would suffice."

  A large number of generators sounds like a backup, but in actual use, the larger the number, the more problems will occur.

   "Two main generators? If this is the case, then the power of the generators will have to be greatly increased!" Babbage frowned slightly: "I'm afraid we don't have such generators in our country?"

"Yes." Qin Tao nodded: "Two main generators, the power of a single generator needs to reach 10 megawatts, so that the two generators are 20 megawatts, and then paired with two diesel generators, the power of each generator is 3 megawatts, so Two 6 megawatts, with a total power of 26 megawatts."

  Babiqi frowned: "Mr. Qin, you said that these data are simple, but it will be difficult to realize. I have never seen such a large marine generator system."

   Babbage cannot be blamed for this. After all, Babbage is only in charge of the aircraft carrier. He has not dabbled in the power system used by domestic submarines. Even if he holds meetings in China at certain times, he has not had much contact with it.

   "This project still needs Ma Gong's cooperation." Qin Tao said: "Currently he is designing a generator for our Mingzhou Group's nuclear power plant, and the estimated generating capacity is 40 megawatts."

   "What? Is it a single generator?" Babbage was stunned.

  Qin Tao nodded: "That's right."

   Babbage gasped, a single generator has already moved 40 megawatts? This is too powerful, right? The East actually has this kind of technology? Not even when their red empire was at its strongest!

   "If this is the case, then there is no problem in designing a 10-megawatt turbogenerator, and we can arrange it according to this!" Babbage was very satisfied.

Qin Tao knew that Mr. Zhao from Institute 704 was also excellent in this area. He and Mr. Zhao had worked closely together before crossing. Therefore, it is estimated that it is still difficult to take the lead.

   Therefore, the power supply project of the entire warship has to be done by horsemen.

   In the future, when Mr. Zhao emerges, you can also go to him. A single turbogenerator can reach 20 megawatts of power, so two of them will be 40 megawatts, and the power of electromagnetic ejection is enough.

Now, it's really not necessary now, after all, electromagnetic ejection can't come out all at once. This half-baked aircraft carrier probably won't have the chance to enjoy the elegance of electromagnetic ejection. However, you can reserve space in case there is any modification in the future. needs.

   "If this is the case, our warship has the strongest power generation capacity among conventional power sources." Babich said.

  Among the conventionally powered aircraft carriers, Da Mao's Kuznetsov, like Babbage's plan, has a power generation capacity of 22.5 megawatts, far exceeding the Kitty Hawk class.

  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 (it is also said that 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 4 sets of 4 MW steam generators, 4 sets of 0.25 MW gas turbine generators, and 4 sets of 0.8 MW diesel generators, with a power generation capacity of 19.2 MW. (Quite a lot)

   Now, Qin Tao's plan will reach 26 megawatts of power generation, which is not comparable to nuclear-powered aircraft carriers, but it is definitely the first among conventional-powered aircraft carriers.

"Our warships need to install a lot of electronic equipment, all of which need to consume electricity, so we must have sufficient power reserves." Qin Tao explained: "This is just the beginning. In the future, the aircraft carrier we designed and built by ourselves will Twice that amount of power generation might be needed."

Babich nodded and continued: "Let's talk about other subsystems, the most important thing is the air conditioning system. In order to adjust the air for the entire warship, we need to install five turbo compressor Freon refrigerators for it. 2 million kcal per hour respectively."

   Qin Tao has no objections to these.

  Mr. Liu has been listening by the side, with longing in his eyes.

   After finishing talking about the power system, he slowly talked about the arrangement under the front deck from the back to the front.

"Under the front deck, there is an anti-ship missile launcher. In the era of the Red Empire, this device was the mainstream, but now, we can only give up." Babich said: "However, this is the original design after all, so if we It would be dangerous to open it up to expand the hangar area."

   Here, Babbage is very troublesome.

  In the original design, this place is used as an anti-ship missile launching mechanism. The 12 powerful shipwreck anti-ship missiles are a wave of terrible blows to the enemy's aircraft carrier formation.

   After all, if you want to break through the protective circle of the enemy's aircraft carrier formation, you have to conduct a saturation attack, and you need to have many batches, and this is just one of them.

After the collapse of the Red Empire, the previous Kuznetsov was taken away by Da Mao. There must be anti-ship missiles in it. In order to prevent military secrets from being leaked, Da Mao will never allow the export of related technologies to other countries. Eastern.

   Now, this place is empty.

  Although there are anti-ship missiles in China, it is not suitable to put them here. After all, they are too small to be of the same order of magnitude.

   "How about changing this place into a canteen?" Qin Tao said: "Anyway, this semi-finished product is just a seed of our motherland's navy aircraft carrier. It is more suitable as a naval aircraft carrier training ship. The real aircraft carrier has to be built by ourselves."

   Commissary?

  Wu Shengli was so startled by Qin Tao's words that his eyeballs almost dropped. You kid, are you serious? What commissary?

   There are no commercial organizations on the navy's warships. After going to sea, eating and drinking are all on the warships, and there is no need to spend money. Qin Tao even needs a canteen, which is a bit too much.

   "Is it a supermarket under the Mingzhou Group?" Another leader said with a smile.

   "If the Navy wants to, we can contract it."

"The navy has stopped doing business for a long time!" Wu Shengli finally couldn't help it, and was extremely dissatisfied with Qin Tao's joking attitude, but then, he thought of something: "Taozi, when you were designing nuclear submarines, didn't you Is there an anti-ship missile launch compartment reserved for our nuclear submarine?"

   Anti-ship ballistic missiles?

  When Qin Tao heard this sentence, there was also a car in front of Qin Tao.

  Yes, how could I forget this?

  We don't have the old Maozi's anti-ship cruise missiles, but we 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 insert our own 850 mm launch tube. The length of ten meters is almost enough. used.

   In this way, this aircraft carrier of our own side can launch anti-ship ballistic missiles?

   "Do you have anti-ship ballistic missiles?" Babbage was also stunned. This kind of thing existed in the old Maozi's era, but he gave up later. Unexpectedly, it was developed and matured in the East?

"Relevant units are currently studying it." Qin Tao said: "It seems that there is a possibility of installing it, so this device will be kept for now. When our small anti-ship ballistic missiles mature, we can stuff them in. Once If there is a situation, try shooting one to scare those **** to death."

  Qin Tao's words made the big guy laugh out loud.

   "Mr. Qin, you are not opening the canteen anymore?"

   "Well, I won't open a canteen anymore, and I will deliver express delivery instead."

"express delivery?"

  It’s only been 1995, and online shopping in China hasn’t risen yet. People only know how to send things by post, and they don’t quite know the meaning of express delivery.

   "That's right, Dongfeng Express, the mission must be fulfilled, you will know in the future, let's continue."

The current anti-ship ballistic missile is developed on the basis of Dongfeng 21. It is too large and has a diameter of 1.4 meters. It is destined to be unable to be carried on ordinary warships. Therefore, everything needs to wait until a new type of missile with a reduced size comes out in the future. After that, it can be plugged in.

  So now, it can only be reserved.

  Anyway, it doesn’t matter if there is a canteen or not. If you have a rich life, you have to continue to work if you don’t have it.

  After talking about the lower deck, it's time to talk about the upper deck.

  First is the deck. There is nothing to say about this. The layout hardly needs any adjustments or changes, just follow the original one.

"There are two take-off lines on the deck, and three take-off points. The roll length of the first and second approach points is 105 meters, and the third take-off point is behind the second take-off point, and the distance increases to 195 meters. According to Kuz The test on the Netsov has a take-off capacity of 29 tons and 32.8 tons respectively. Since the upturn angle of this warship reaches 14 tons, it is impossible for the maximum take-off capacity to reach 33 tons when the aircraft carrier is sailing at full speed any questions."

Speaking of ski jumping, a very popular saying is that it cannot take off with a full load and cannot take advantage of the load of the Su-33 fighter jet. This kind of statement is inappropriate. In 1989, Lao Maozi was on the Kuznetsov A large number of take-off experiments have been done on the ground. When the warship is sailing at full speed, the 32.8-ton Su-33 has absolute safe take-off capability. The flying speed reached 185 knots and the height was 38 meters. Relying on the advantage of the angle of the ski jump, it continued to climb upwards, and continued to accelerate to the recovery speed of 328 knots without dropping any altitude, and then performed various maneuvers.

   Even, the crazy old Maozi tested the take-off with a weight of 38 tons at an apogee of 195 meters. After flying out, the trajectory became an anti-S shape, but he could still recover smoothly, so it became the limit take-off weight.

   It is a layman's term to say that heavy load takeoff is not possible, but another disadvantage of ski jump takeoff cannot be concealed: low deck utilization and low aircraft dispatch efficiency.

  Compared with the swishing ejection of the catapult, the ski jump takeoff is too slow, especially when taking off at afar, and it will interfere with the landing area.

Therefore, catapult takeoff is definitely a trend, especially electromagnetic catapult, which does not consume precious water vapor, and the deck does not freeze. American aircraft carriers will continue to drop in speed after continuous catapults, because the steam is not enough, and they have to Take a break and gather your energy.

   As for now, first solve the problem of availability, efficiency, etc., are all things in the future.

   "The last is the island." After talking about the deck, Babich continued to talk about the layout of the island.

"According to the original plan, a four-sided phased array sky sentinel radar needs to be installed on the ship island." Babich continued: "But after arriving here, I think it may need to be modified. There are mature Meepo long-range alerts here. The radar, in combination with our roof radar, can be used to scan 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.

   "Installing a four-sided phased array radar? Where to buy it?" Babbage was a little surprised.

At present, no four-sided phased array radar has been seen on a warship in the East. The only air defense destroyer in service is modified from the radar of the S-300 system on land. Even if this device is installed on four sides , that is only four systems, which will not be combined.

  Actually, even the Sky Sentinel Radar does not perfectly solve the system combination problem, which requires powerful computer processing capabilities.

"Of course it is our domestic related institutions. The active phased array radar developed by them is undergoing testing." Qin Tao introduced: "It is placed on our warships, it does not need to guide anti-aircraft missiles, it is only used to scan the surrounding space, it should be able to It is simpler. When our aircraft carrier is repaired to the bridge, the phased array radar should be able to catch up with the construction schedule."

  Active phased array radar?

  Babbage opened his eyes wide again: "You guys actually have a shipboard 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, and active phased array radars on fighter jets are also under development.

  As for Lao Maozi’s Sky Sentinel, of course, it is undoubtedly a passive phased array. There is no active phased array radar installed on a warship in the world. Now, this ship under my command will be the first?

   "Yes, it should belong to the first set 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 found immediately."

  The U.S. aircraft carrier does not have a four-sided phased array radar, but uses a common parabolic antenna radar. 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. The old Maozi went to the four-sided phased array to better increase the detection capabilities of the surrounding airspace. Of course, his own aircraft carrier is no exception.

"With the four-sided phased array radar, it can complete the uninterrupted tracking and threat determination of a large number of targets, and at the same time, it can also be integrated into the command system of our warship." Qin Tao said: "Of course, other related There are also a lot of equipment, and we need the assistance of our relevant departments. When we are designing, we can reserve them first. After all, the transformation will start from the bottom."

  Babbage nodded.

  The development of electronic equipment is too fast. Now their design may not be able to directly determine all the electronic systems, and they can be modified at any time in the future.
