Warship of Great Power Chapter 242

  Chapter 242 The 400,000-ton dock did not cost money

"Brother Tao, I'll go back to Huating by myself. If you want to go to Bincheng Diesel Engine Factory, then go." In the room, the lights were dim and the atmosphere was good. Zhao Ling stuck her head into Qin Tao's chest and said to him .

  It was already evening, and this meal lasted from noon to night before the guests dispersed, and it was time for Qin Tao and Zhao Ling to go back. After all, it was time to go to work on the third day of the Lunar New Year.

  Qin Tao shook his head immediately: "That's not acceptable. Since we came together, we have to leave together. This is something to be particular about."

   "But, don't you want to see the experts from the island country?" Zhao Ling said, "Let's stop talking about superstition. Since you want to see it, of course I can't drag you down."

"The experts are coming, but it doesn't mean that they will come tomorrow. Moreover, after coming, they will not leave immediately. They have to investigate there before they can draw a detailed investigation report, even if it doesn't take ten and a half days. It's only a month, and I have to stay for a week, so why should I be in a hurry.”

   Creak, at this moment, the door opened.

  Zhao Ling quickly moved her head away from Qin Tao, then looked at the door, and found that it was her father who came in.

   "Dad, you really are, why don't you know how to knock on the door before you come in?" Zhao Ling glanced at her father dissatisfied: "Your daughter is already married, so she has privacy, okay?"

"Oh, oh." Wu Shengli quickly agreed, but still walked inside, and then sat on the chair opposite the bed: "Taozi, there were so many people just now, I didn't say anything. I heard you were at Huating , and brought up our new frigate plan with them?"

  Qin Tao was picking up his wife at the time, so he mentioned it by the way. Who would have thought that it would be reported to the old man so soon. I really don't know who told it. Could it be that there are intelligence personnel there?

   "Yes, but we should go." Qin Tao said, "Xiaoling should go to work tomorrow."

   "I have already said hello to the other side, and I have asked Xiaoling for a day off. You have come all the way, you have to stay at home for one night, and you will leave tomorrow during the day." Wu Shengli said.

   "Dad, how can you do this?" Zhao Ling was anxious: "I can't be special, so what will other people think of me? Do you know?"

  Zhao Ling quit, she is married, but her father is still interfering in her private affairs, what is going on?

  Zhao Ling was very dissatisfied.

   "I told the other side that you are going to attend a meeting of the Navy Department, and you are on business." Wu Shengli said.

   "Meeting, what meeting?" Zhao Ling still looked at her father annoyedly: "How can you lie?"

   "Of course I didn't lie." Wu Shengli said: "The theme of this meeting is the technical demonstration of the Navy's new generation of frigates."

   "Cut." Zhao Ling glanced at him: "The meeting place, the participants?"

   "The location is at our house, and there are three participants in the meeting!"

  Qin Tao looked at Wu Shengli, a little funny, alas, why did he say that? However, since my father-in-law is so eager, I might as well just say what I didn't finish.

   "Okay, then let's go to the study, Dad, I need to use your desk and draw a design drawing along the way." Qin Tao said.

   "Okay, let's go to the study!" Wu Shengli walked out with his hands behind his back, looking like a leader.

  Qin Tao glanced at Zhao Ling: "Let's go, it's fine to go during the day tomorrow, and rest tonight."

   "Hmph, are you still resting? This meeting will last almost until dawn." Although Zhao Ling complained, she went out with Qin Tao and entered her father's study room. Wu Shengli had already put away the drawings and drawing tools.

   "Dad, you can first listen to Xiaoling tell you about the development progress of Hongqi-16, and I will draw a picture here first."

  At this time, Zhao Ling has put on a new expression. Since she has to report to work, she should be more serious.

  Zhao Ling continued to explain everything from guidance principles and methods to internal structure and imitation progress.

   After Zhao Ling finished speaking, Qin Tao's drawings were also drawn. Anyway, it was just a sketch, so there was no need to be so detailed.

   "The superstructure is all tilted inward, similar to a missile boat. This also considers the requirements for stealth performance?" After seeing the design drawing, Wu Shengli was immediately curious.

In recent years, domestic shipbuilding technology has been continuously developing. The early 051 did not have any consideration of stealth at all. From the outside, there are various masts, missile launchers, antennas, etc. everywhere. When it comes to 052, the appearance looks The 051C is more concise, and the design drawing of the new frigate in front of us, the side of the ship, has been completely wrapped up, and the overall shape is very simple.

"Yes, stealth is a trend. All countries are doing it. We must not fall behind. Even if we reduce our 4,000-ton frigate to 2,000 tons, the radar reflection area of ​​a 1,000-ton frigate is not bad. .”

  Wu Shengli nodded: "This design looks very good. Are the anti-aircraft missiles deployed in front?"

   The first thing to look at is the shape, and the second is to look at the position of the air defense missile. After all, what the navy lacks most is the air defense capability.

"That's right, it's the most suitable position to deploy at the front and behind the naval guns. We are now using the wheel launch method, and we have arranged four sets of eight-pack launchers, so that we have thirty-two ammunition, which is also considered It is enough. When our thermal emission technology matures in the future, this space can be reduced.”

  Qin Tao is down-to-earth. It is unrealistic to engage in hot launch now. We will use cold launch first, which will make the silo a little bigger and crowded, and it will be more convenient later.

  At least it is much stronger than Haihongqi 7!

   "Let's look at the rear again. On the mast is the roof radar, and behind it is a separate large chimney." Qin Tao continued.

   "There is only such a big chimney? What kind of power does it use?" Wu Shengli became concerned.

   "Diesel, of course."

  Although the displacement is not much lower than that of the 052, it is a frigate after all, and there is no need to pursue such a high speed. There is no need for such a tall gas turbine, and a simple diesel engine will do.

   "We only need to use four diesel engines, with a total power output of 20,000 to 30,000 horsepower. We don't count on 50,000 to 60,000 horsepower like the 052."

  052 uses two LM2500 gas turbines, which can output 55,000 horsepower, and push this kind of warship to more than 30 knots. For a frigate, that kind of power is quite a luxury. As for the frigate, 20,000 to 30,000 horsepower is enough, and it can run at 26 or 7 knots.

   But Wu Shengli still had to frown: "Four engines, with an output of 20,000 to 30,000 horsepower? This is a bit difficult, right?"

   Even the most technologically advanced Bincheng Shipyard does not have such an advanced engine with a single output of 7,000 or 8,000 horsepower!

The country has always been troubled by the heart. To build advanced third-generation tanks, there is no suitable high-power tank engine. To build advanced third-generation fighters, there is no advanced aero engine. The same is true for ships. Although they can be produced, they have already behind.

Qin Tao nodded: "Yes, the diesel engines we can produce now cannot reach this level, but as long as we modify the diesel engines we imported from France before and use STC technology, we can achieve a breakthrough in engine performance. Meet our needs."

   "French diesel engine, improve it?" Wu Shengli was still a little curious: "Can we make it ourselves?"

  Qin Tao nodded: "When we introduced French technology back then, we were tricked by others. They concealed a lot of technology."

"You mean, the French PA series of medium-speed high-horsepower diesel engines we introduced in 1978 still have room for technological improvement?" Wu Shengli became inexplicably excited when he thought of this: "Then let's find time to go to the diesel engine factory in the old area to investigate. , see if we can do it."

  In 1978, China National Technology Import and Export Corporation signed an agreement with the French Thermal Engine Association to introduce the PA series of medium-speed high-horsepower diesel engine patents, which were then handed over to the old diesel engine factory by the Sixth Engine Department for trial production and manufacturing.

   It is said that it was early enough at that time, but it was not widely used on 054 frigates until after the new millennium. What have you been doing all these years?

   Of course it was because the French kept a hand.

In that year, the country spent huge sums of money and signed a special "S.E.M.T-PIELSTICK PC2 and PA6 Diesel Engine Licensing Agreement". The cylinder output power is 400 horsepower, and there are two types according to the cylinder arrangement, in-line L type and V type. The former has 6, 8, and 9-cylinder models with a power of 2,400-3,600 horsepower, while the latter has 12, 16, and 18-cylinder models with a power of 4,800-7,200 horsepower.

After the technology was introduced, the diesel engine factory in the old area immediately started trial production, starting with the simplest 6PA6L type, and soon a trial-produced engine with a power of 2,400 horsepower was produced. However, it was still too small for marine use, so it was mainly used on diesel locomotives. Later, we made persistent efforts and produced 12PA6V.

  The first batch of 12PA6V was installed on the Type 918 minelayer, and after the performance was verified, it was used on other missile boats.

   That's it, it's the 1990s.

   No one knows that the French concealed the most important STC technology.

In later generations, old drivers despise turbocharging every day, squeeze power, and talk about self-priming for thousands of years. In fact, turbocharged engines have a very old history, and marine diesel engines have also been used. Turbo, but not enough.

   To get better performance of PA6 diesel engine, STC (Sequential Turbo Charging) sequential supercharging technology must be used.

   This sounds a little confusing, but in fact, two different superchargers are connected in parallel to form a more reliable supercharging system, which is somewhat similar to that used in later generations of high-end performance cars.

  The reason is also very simple. The turbocharger is driven by the exhaust gas from the engine. The higher the engine speed, the higher the efficiency of the turbocharger. However, it is impossible to fully meet the needs of various working conditions with only one turbocharger.

  Take a car as an example, using a large turbo can make the power data look better, but the burst of torque will be later, and a small turbo can blow up earlier, but the follow-up is weak.

  If you use two different turbos to match, you can meet your needs. This is the twin turbos used in some high-end performance cars.

  Marine diesel engines also need this technology.

For the same engine, as long as this technology is used, it can not only improve the performance of the engine at low working conditions, but also increase the power of a single diesel engine when the two superchargers work together at full power. Ten percent!

Because the French did not provide it, so the country can only do it by itself. It took more than ten years to design the relevant STC supercharger, and then verified it in one of its own 12PA6V-280; followed by the development of 16PA6V -280STC diesel engine. Finally, the domestic diesel engine has also achieved a power output of 7,000 horsepower, and it can reach more than 7,700 horsepower during short-term overload operation, which has become the power of the new generation of domestic frigates.

   However, it is still incomparable with France. France's own frigates use 12PA6V-280STC engines, as long as 12 cylinders are enough. This engine has also arrived in Baodao along with the Lafayette-class frigates.

   Now, since Wu Shengli is interested in these, Qin Tao has revealed all these technologies.

  Wu Shengli is even more eager to try.

"I heard that the localization rate of our domestic PA6 diesel engine has only reached more than 70%. These are not enough, and the relevant units have to continue to increase the localization rate." Qin Tao said: "This can't be too anxious, anyway. It will take time to finalize the Hongqi-16. As for the turbocharger used in this STC technology, we can also find a way to get it from abroad and then imitate it ourselves.”

   Obtained from abroad, imitate by yourself? Wu Shengli's gaze became radiant again.

  Qin Tao has ready-made ones on hand! The Belgian wants to order two bulk carriers. If he remembers correctly, the engines on them are of this type. After the engines arrive, they will take a chance to disassemble them and have a look before imitating them.

   "Brother Tao, although we don't have the opportunity to merge the diesel engine factory yet, we can already find an opportunity to supply the diesel engine factory." Zhao Ling said.

  Qin Tao spat and talked all afternoon, but did not finalize the matter of a suitable diesel engine factory. Now, the diesel engine factory is put aside for now, at least it can provide supporting equipment for the diesel engine factory.

  The parts that Qin Tao mentioned must be produced in his own factory. The propeller factory in Huating can use CNC machine tools to make a few turbochargers, which is no problem.

   "Yes, this is one foot into the threshold of making diesel engines." Qin Tao said with a smile, and Qin Tao was very satisfied with Zhao Ling's mouthful of each of us.

   When it came to the design of the new frigate, Qin Tao and Zhao Ling went back to sleep in the middle of the night, and then set foot on the return journey. On the night of the third day of junior high school, Zhao Ling was finally sent to her destination, and stayed in the comfort zone of Huating for another night. Qin Tao returned to Mingzhou Shipyard on the fourth day of junior high school.

  As for the engine builder from the Bincheng Diesel Engine Factory, it's not too late to see him again in a few days.

  When the car approached the shipyard, Qin Tao saw two people standing like door gods at the gate. After getting closer, he realized that they were actually those two foreigners!

   "Mr. Qin, you are finally back!" Carrasco said with a sigh of relief, "You have left us for the past two days, but we are very anxious."

   "Yes, Mr. Qin, we still want to confirm the details with you. If there is no problem, we can sign the agreement." Kami said.

What? It's only been hanging out for two or three days, and you've made up your mind? Qin Tao was a little surprised, why did they make a decision so quickly?

   "In terms of delivery time, we hope that after signing the contract, the ship will be delivered to us within one year."

  The delivery event is so stuck?

  Qin Tao rolled his eyes, and then asked: "Another boat accident? Didn't you see any reports?"

   "It didn't sink, but the inspection found that there were cracks..." Before Carrasco finished speaking, Kami stopped him with his eyes. How can you say that? Isn't this leaking the company's secrets?

  However, the words have already been said and cannot be taken back.

Qin Tao smiled: "Don't worry, our group is honest and trustworthy, and we will never intentionally make things difficult for our customers when they are in crisis. We agreed on a 60 million ship, that is a 60 million ship, we will definitely Will not take this opportunity to raise prices."

  Cami breathed a sigh of relief.

  The original ships of their company were sufficient, but two ships sank in a row, and the transportation capacity was tight. Now another one has found a crack, and the transportation cannot be continued for safety reasons. As a result, they became nervous.

  Those retail customers don't need to transport, but the goods of the partners all the year round can't be delayed!

For example, if they transport iron ore from Australia to Europe, they cannot delay it. If it is delayed, the customer's steelmaking plant will have to stop working. They cannot afford this loss. If other transportation companies take over, then they will You might lose a big client.

  They must quickly build new ships, and shipyards from various countries are unwilling to accept them, so they can only pin all their hopes on Mingzhou.

   At this time, Qin Tao didn't take advantage of the danger and raised the price for them, so that Kami finally let out a long sigh of relief, but then, Qin Tao spoke again.

"However, the time limit you requested is too tight. It is impossible for us to build ships for you now. You have seen it in the shipyard in the past few days. All of our shipbuilding stations are full." Qin Tao Said: "The 150,000-ton bulk carrier you requested can only be built by our 400,000-ton shipyard, but at present, this shipyard has not yet been built! So..."

   So what?

  Cami already had an ominous premonition in her heart.

   "We estimate that it will take at least half a year to build the dock and then build a cargo ship for you. Therefore, the delivery time will take at least one and a half years."

"No, no, we can't wait so long, we hope to get a brand new and strong bulk carrier as soon as possible!" Kami was very anxious. During this year, they had to tear down the wall to make up for the wall, and even leased other transportation companies After a year, if they still can't get a brand new bulk carrier, then their company should probably go bankrupt.

  One year is already the longest.

"However, there is nothing we can do." Qin Tao said: "Without a dock, we can't build ships. If we sign a contract with you, we won't be able to build them at that time, and you will seek high compensation. Therefore, we Absolutely not."

  Qin Tao's words are also reasonable, it's hard for a smart woman to cook without rice. Now Qin Tao sympathizes with them and signed the contract.

   "As long as you can build the ship for us within one year, when we sign the contract, the date clause can be removed, and we don't want compensation!" Kami said quickly.

   "I'm sorry, there is nothing we can do." Qin Tao continued to be very polite.

   "Well, we are willing to provide sponsorship for your dock construction!" Seeing that Qin Tao was about to leave, Kami was also anxious and shouted immediately.

   "Sponsorship for our shipyard?"

"That's right, we have to have a dock before we can build a ship, and we are in a hurry, so we are willing to contribute a sum of money, and you can use this fund to hire more workers and speed up, preferably within a month. Build this shipyard! Please also see that on the basis of our sponsorship of the shipyard, hurry up and build us a ship within a year. Of course, even if it is overdue, we will not ask for compensation. "

   "If you are willing to pay 20 million US dollars, then we can consider it." Qin Tao said.

What? Twenty million? Do you want so much?

Kami wanted to bargain, but swallowed the words back. After all, this is their last chance. It is worthwhile to spend 20 million dollars to buy time. When the new ship is built and put into operation, it will soon Will make money back.

   "President Qin, we are willing to pay 20 million yuan, and please arrange to build a ship for us as soon as possible!"

   "Okay, I will focus on taking care of you. At the same time, we will also find a way. Before the dock is built, we may be able to find a way to do some preparations."

   "Well, that would be great. But please ensure the quality, we don't want accidents."

"Don't worry, there will be no problems in building civilian ships with 400 MPa steel." Qin Tao said, "You will also send corresponding quality supervision personnel. You can spot-check the steel plates we use at any time. If they fail to reach this level We are willing to make corresponding compensation!"

  Qin Tao promised to use high-strength steel to build the ship, which also reassures Kami. Although it is a bit expensive, it is strong!

   Paying an extra 20 million yuan is something that can't be helped.

"When these two ships are built, they will prove their value during the voyage, and we will further design better ships, such as 200,000-ton bulk carriers, with better operating economy. We will have many opportunities to cooperate in the future.”

  The contract was signed that afternoon. Cong Ju was extremely surprised when she saw the terms of the contract.

  These people are spending a lot of money to build ships here, especially, 20 million to help them repair the dock. This money is enough to invest in the entire dock. In other words, the dock built by our side cost nothing at all!
