Chapter 421 GT-15000 Prototype Ignition

  These words are a bit heartbreaking.

   After all, for Makarov, the Varyag was his last hope, the most powerful warship he built before retiring! He wanted to give the warship a good home.

He always hopes that this warship can be ready to go and gallop across the ocean, but he also knows that this hope has become more and more slim. It's the same, it's better to sell it to Mingzhou Group.

  Mingzhou Group helped a lot when dealing with nuclear power scrap iron, and Qin Tao also became Makarov's friend.

  Now, Makarov had a sad expression on his face.

  The best object was Ah San, but they were so angry that they wanted to leave. Now, even if they begged again, they wouldn't want Varyag anymore.

  The second target is the East, but it seems impossible now, people can produce their own, making more advanced ones, why buy their semi-finished products?

   Next, what customers?

  Europe is impossible. Those countries in Europe either don’t need it or create it themselves. Looking around the world, they can’t find a third country!

"Of course, selling to us is the worst choice. After all, the price of scrap iron is too cheap, so if you have a better choice, you can try to sell to others." Qin Tao began to give them advice: " In my opinion, the rainbow country, Brazil, Argentina, these countries are all possible, you can go lobbying."

   Is it possible that these countries are getting poorer one by one, do they have this kind of strength?

   Those countries in the oil region are okay, but those countries do not have the strategic needs for global deployment, and there is no need to buy aircraft carriers!

   Makarov was completely depressed.

   "Is there any place you want to visit?" Qin Tao asked.

   "We want to go to the Mingzhou Iron and Steel Plant, which is said to be able to produce 1 gigapascal of steel." Asnayev said.

   This is a person who does not shed tears without seeing the coffin.

"The steel of 1 gigapascal is not stable. We can stably produce 800 megapascals of steel, and then select some steels with better quality that can reach 1 gigapascal for use. I can show you look."

  So, after breakfast, Qin Tao took them to Mingzhou Iron and Steel Plant.

  The scale of this iron and steel plant is also getting bigger and bigger, with blast furnaces everywhere and chimneys rising. On the production line, they saw the latest batch of high-strength steel produced. Looking at the test results, they were speechless.

  That night, they returned to Ermao on a passenger plane. Qin Tao happily ran to find his father-in-law.

   "Where's Makarov?" Wu Shengli asked curiously.

   "Sent away."

   "Leaving? We haven't negotiated with them yet, leaving so soon?"

   "What are you talking about? The navy talks to them, it's 400 million US dollars, and I talk to them, 100 million is almost the same." Qin Tao said.

  Actually, Wu Shengli originally wanted to be a companion, but was rejected by Qin Tao. Qin Tao took Ermao Yitong around, and then he was fooled away, just to prevent them from contacting the navy.

   You must continue to let the old man hang out!

   "100 million?" Wu Shengli sighed, "That's not a lot."

"The price on the surface, 20 million is enough, but it takes a lot of money to manage it behind the scenes." Qin Tao said: "This time, they have completely lost confidence. I think that within half a year, they will He will definitely contact us and let us buy that warship at the scrap metal price."

   Directly went up and said to buy scrap iron, Ermao would go to **** if he didn't get annoyed, Ah San was the first to pounce on it, but he was asked for two billion US dollars!

  This kind of thing, don't be in a hurry, you have to let Da Mao slowly see the status quo and reality, so that you can accept your fate.

   "Within half a year, we still have to wait half a year." Wu Shengli sighed.

   "Yeah, it's useless to be anxious. Our navy doesn't have professional Aegis warships. It won't work by relying on 054. There are no **** warships. If the Varyag is brought back, it won't be able to form a fleet."

  Qin Tao was also in a hurry, wishing he could pull it up immediately, but the meal needs to be eaten in one bite, so don't be in a hurry.

  Hearing what Qin Tao said, Wu Shengli remembered something: "Our gas turbine imitation has made great progress. I heard that the first gas turbine has been imitated over there!"

   "Really? So fast?" Qin Tao was also extremely excited: "Then let's go and have a look?"

   Facing the excited Qin Tao, Wu Shengli nodded solemnly: "Of course, I'm planning to go and have a look."

   Time has entered 95 years. On January 1 of this year, Qin Tao, Wu Shengli and others came to the 703 Ice City.

  It is very cold here. In those uninhabited places, the snow may even be one or two meters thick. However, the 703 Institute is steaming.

  Although it was a holiday, the researchers did not take a break. They were all excited about the big guy in front of them.

  “Although in terms of volume, our GT-15000 gas turbine is much larger than the LM2500 gas turbine, but its performance is not inferior to that of the LM2500, and its power is even better.”

   "That's right, we have mastered all the materials and processes. We already have the capacity to mass-produce this gas turbine."

Listening to everyone's words, Old Wen shook his head aside: "Everyone, this is just the beginning. Although we have created it, we haven't tested it yet, so we don't know how reliable it is. Moreover, in terms of its current power, , can only drive a 5,000-ton warship, and the output power is slightly lower."

   "Two are not enough, let's install four, enough to drive an 8,000-ton warship." Someone next to him said.

  Wen Lao smiled, knowing the mood of the big guy at this time.

   At this moment, there was a rush of footsteps outside.

   "It's built? It's great. It solves the problem of heart disease, and our warships will be able to serve dumplings in the future!"

   "Boss Qin?" Mr. Wen immediately recognized it, and turned his head to look outside.

  Qin Tao, Wu Shengli, and all other naval officers followed. There were more than 20 people, and the team was very large.

   "Boss Qin, what brought you here." Elder Wen asked with a smile.

   "What wind? Of course it is the wind of the gas turbine." Qin Tao said: "We dare not build destroyers on a large scale because the gas turbines are not enough. Now, we finally built it ourselves!"

   "Mr. Qin, at present we have only completed the imitation of the UGT-15000 gas turbine, and have not put it on the test bench. The scheduled output power is 20 megawatts. We will name it GT-15000 now."

   Just in front of the intake vane of this gas turbine, there is a huge red baffle with white characters written there: GT-15000.

   This naming method is simple and direct.

"If the output power is 20 megawatts, it is really embarrassing." Qin Tao nodded: "If you drive a 6,000-ton warship, it is difficult to achieve a speed of more than 30 knots, especially now that our warships pay attention to seaworthiness, and they are getting wider and wider. .”

The speed of a warship is not only related to power, but also to the design of the hull. In the past, warships during World War II could achieve very good speeds without high power. For seaworthiness, the aspect ratio of warships is getting smaller and wider, so with the same displacement, the power required will become stronger and stronger.

  So, when the 052C was built, UGT25000 was used, and the power was increased to 26.7 megawatts. Two units can propel a warship of 6,000 to 7,000 tons, and four units can propel a warship of more than 10,000 tons.

What now?

   "Yes, this is just the beginning, we still need to improve and increase its power." Wen Lao said.

Hearing his words, an expert on the side said: "A lot of aero-engine technologies are applied to the gas turbine. If we want to improve it, we need the strong cooperation of our 430 factory. We hope that all the drawings can be handed over to us. , so that we can better assist.”

  Hearing this, Qin Tao showed a smile on his face: "Mr. Wen, this expert from Factory 430 is just making fun of you guys."

  Wu Shengli frowned, what do you mean by that, are you provoking on purpose?

The 703 Institute was originally researching marine steam turbines, but now it has transitioned to gas turbines. Many technologies are lacking. Therefore, in the development process of this engine, they not only cooperated with the steam turbine factory in Bingcheng, but also cooperated with the old area. The 430 factory.

  The engine in front of me, the gas turbine part, was handed over to the 430 factory for imitation.

   The big guys are considered brothers, how can Qin Tao say that?

"Mr. Qin, that's not what we mean." The expert said: "Aero-engines move the whole body with one stroke, and this gas turbine is the same. It's the same thing for us to imitate according to the original drawings. Changes may bring about unexpected situations, so we want a full set of drawings to better help research and development."

   "So, since you have requested a complete set of drawings, will you be responsible for any accidents during the research and development process?"

   Now, the other party stopped talking.

  Mr. Wen seemed to understand what Qin Tao meant.

   Various factories in China are both cooperating and competing. If the brother factories get a full set of drawings, will they use them for their own development?

"We have obtained a lot of technical information, and we have fully understood the technical information of UGT-15000. Therefore, we should be responsible for the upgrade on the basis of these technologies. If there is a problem, I will be responsible. "

  Back then, when Qin Tao first met Wen Lao, it was the same situation. With so many people present, no one was afraid of being responsible for the villain, so Wen Lao stood up and I will bear it!

  Later, the machine was disassembled and the fault was found.

   Now, the same is true, a project must be fully responsible for someone!

   "Where's Mao Youwei?" Qin Tao asked.

  The experts invited from Lao Maozi will have a new name when they come here, which will make it easier to work and say goodbye to the past.

After Sergey of the Shuguang Bureau came over, he also gave a name. This name was given by Sergey himself, Mao Youwei, which means that he still has something to do when he comes here. However, adding the previous name, There may be an antonym.

   "He is leading a group of people to work on the GT-25000 gas turbine. He is not interested in our imitation." Wen Xueyou said.

  For the 703 Institute, for the motherland's naval gas turbines, the birth of the prototype is a breakthrough, which means that domestic warships will have 20 megawatts of gas turbines, but for Sergey, it is nothing at all.

Those massive draft papers were all brought to Institute 703, and they were classified and analyzed here. After Sergey came, he brought a lot of materials, plus the contribution of the designer Sergey. Therefore, this engine Came out without any problems.

   What Sergey cares about is the development of follow-up models. Before the disintegration of the Red Empire, Sergey was developing improved products. Now, he is devoting himself to the modification.

  Qin Tao nodded: "Let's go and have a look later."

   There is no rush yet.

"In my opinion, with Mao Youwei leading the team and Wen Lao and the others, there will be no problem with the modification plan, so we don't have to worry about it at 430 Factory." Qin Tao looked at the technician: " In the future, you can just follow the design drawings here and help manufacture gas turbines. By the way, our domestic related technologies are also constantly developing. It is said that single crystal turbine blades are also being developed. If this technology can be used, it will be even better. alright."

  The group of experts brought from the Rainbow Country should have stabilized and entered the field of research and development. I don't know what the results of their research and development are.

  The expert nodded and stopped asking.

  Qin Tao continued to look at the gas turbine: "The power is a bit embarrassing, Mr. Wu, I think, how about we simply install four gas turbines and build a warship of more than 8,000 tons?"

   Two engines can drive a 5,000-ton warship, but for the Aegis battleship, this displacement is still very small.

  The development of warships is gradually becoming larger. The larger the displacement, the more spacious the internal space.

  Wu Shengli frowned upon hearing Qin Tao's words.

  Eight thousand tons, you really dare to think about it! Don't you know that the greater the displacement, the higher the procurement cost? For the navy, not only quality is needed, but quantity is also needed. For the same money, building two ships will definitely play a greater role!

Fortunately, Qin Tao did not insist, and he continued to put forward his own ideas: "If the navy does not have high requirements for speed, if we reduce the speed requirements of the new generation of air defense destroyers to about 28 knots, it is also possible to install two such engines. Yes. In this way, a warship with a displacement of more than 6,000 tons can carry 48 anti-aircraft missiles, which is enough."

  Either four units are installed and the displacement is increased to eight or nine thousand tons at the same time, or there are two units and the speed is reduced. These are the two methods. It depends on how the navy chooses.

  Wu Shengli nodded: "Wait for the development of the 346 radar. After all, the test of this gas turbine will take time."

   Now, the prototype has been manufactured, but the test also takes time. Among other things, it is just a durability test, and it has to be turned continuously for several months until it reaches the design life.

  So, all of this will take time. There is no need to worry about Qin Tao's suggestion for the time being.

   "Since everything has been built, is the ignition test going to be carried out next?" Qin Tao asked.

   "Yes, we will start the ignition today." Wen Xueyou said: "Now, start the work!"

The gas turbine is placed in the test workshop, but the intake and exhaust need to be connected to special passages. The gas turbine consumes a lot of oxygen. These pipes are also relatively thick, and there are various flow monitoring equipment inside. .

  Following Wen Xueyou's order, all kinds of preparations started quickly.

  "The starting power has been sent, the switch is in remote, and the starting alarm switch is reset."

   "The power supply of the auxiliary hydraulic oil pump has been sent and it is in automatic state."

  …

   One after another, the instructions continued, and finally, everything was ready.

   "Start the engine!"

  As this command sounded, a technician's hand pressed the start button.

  The starter motor began to rotate, the whistling sound of the turbine came, and the huge engine began to rotate. However, because it was installed on a special base, the vibration was not strong.

  The turbine turned faster and faster, and finally, Wen Xueyou gave the order to ignite.

   Fuel is injected into the combustion chamber to push the turbine blades behind, and the whole machine starts to run on its own power!

  The starter motor is disengaged, and the engine enters the idle working state.

   Start successfully!

   "The indications of all the instruments are normal, and the engine is running smoothly!"

   "Boost power to ten megawatts!"

   "Up to twenty megawatts!"

   "The test run was successful, and the engine reached the design target!"

  Other engines would have to run at low power for a long time to speed up, but the advantage of a gas turbine is that it can run at full power when it is turned on. At this time, everyone applauded when they heard that the rated power was reached.

  In the design department, many people are still working.

  Sergey heard something, stood up from in front of the computer, walked to the window, looked at the test workshop over there, and saw the blue smoke coming out of the chimney, and a smile appeared on his face.

  He did not participate in the test, because he knew that the people here had already mastered a full set of technologies, and there would be no problems in production at all, and the assembled gas turbines could fully meet the design specifications.

  He doesn't need to join in the fun, after all, the more powerful gas turbine is his goal.

  He stared at the window for a few minutes before returning to the computer again.

  When he got the calculator, he was already very excited. Now, using these computers can greatly improve the design ability, and their improved design has made rapid progress.

   At this moment, the door was pushed open, and a gust of cold wind blew in from the outside. Sergey couldn't help but turned his head to take a look, and then looked at the familiar figure in amazement.

   "Boss Qin?"

   "It's me, and the leaders of the navy are here. We are very satisfied after watching the test run of the engine. Come here to have a look." Qin Tao said: "How is your modification research going?"

"In the past few years, we have been researching one after another. After coming here, the progress has been faster." Sergey said: "At present, the design of the zero level has been completed. According to the computer simulation, there is no problem with the matching. Wait for the future experimental verification."

  Qin Tao nodded. This zero-stage compressor is the main technology of UGT25000. As long as this is realized, the research and development will be half successful.

   "At the same time, we also referred to the design of the LM2500 gas turbine and made some improvements, such as designing a split compressor casing and external fuel nozzles, so that blades can be replaced on site and hot parts can be maintained on site."

Although the door to the West is closed, the country still has LM2500 gas turbines after all. In addition to four used on warships, there is also a spare. This gas turbine has been repeatedly referenced and studied by Sergey. Many of the above advanced designs have been used. on this modified product.

   "At present, we are still considering more advanced technologies, such as intercooling cycle. If this technology is added, the thermal efficiency and power can be greatly improved. The engine can reach 30 megawatts."

   As an expert in the field of gas turbine design, Sergey certainly hoped that more advanced gas turbines would appear under his command.

   Then we have to start from the technical principles.

   Intercooling cycle is one of them.

In many cars, an intercooler is used. Of course, only turbocharged models have it. It is because the air becomes hot after being compressed, so the density will become smaller. After passing through the intercooler, the intake air volume can be further increased. Thereby increasing engine power.

  Gas turbines also have this idea.

"Currently, the easiest way is to install an intercooler between its low-pressure compressor and high-pressure compressor, so that the air is cooled before entering the high-pressure compressor, with minimal changes, but, currently in the world, there is no precedent."

   "There is no precedent, we can create." Qin Tao said: "As long as we think it is correct, we must stick to it, so that we can reach the other side of success. Even if there may be difficulties in it, we will continue to move forward."

   Qin Tao fully supports this project, because he knows that this road can work.

There is no precedent in other countries. This is a "high-power marine gas turbine with Chinese characteristics". Needless to say, it is 30 megawatts. After careful adjustment and matching, it is possible to achieve 40 megawatts. By then, two units will be able to drive 8,000 Tons of warships, that scene, just thinking about it is enough to look forward to.

   "That's right, as long as you think there is potential, then do it boldly." Wu Shengli also said: "Our navy will also fully support it."

  The current GT-15000 can only be tested in small batches of equipment. This modification is the most important. To increase the power of this engine, of course we have to support it.

   "Leader Wu, with your words, we will have more confidence." Wen Xueyou said from the side, and he was also very excited at this time.

  Unknowingly, the sky outside gradually darkened.

   "It's evening, shall we have a celebration party?" Qin Tao suggested.

   "Boss Qin, it's only past four o'clock." Wen Xueyou reminded.

  The further north you go, the earlier it gets dark in winter.

   "It's New Year's Day after all, everyone has been busy all day, and it's time to go to the fun." Qin Tao is very generous: "Let's go, let's go to celebrate, and Mingzhou Group will reimburse the expenses."

   "I think it's okay. You don't have to be restrained. Come and eat. They are very rich in the Mingzhou Group." Wu Shengli said.
