In fact, everyone already knows how strong the motivation for this kind of model change is, so if we keep talking about motivation here, that is not what the leader wants to hear. Wen Xueyou also knows that, and after a few words, he turns to other aspects.
"Our GT-15000 has many shortcomings. For example, the cover outside the gas turbine does not completely cover the gas turbine, and the compressor is exposed outside, so the noise in the cabin is relatively loud, the temperature is relatively high, and the working environment is very poor. At the same time, The cover also has no heat insulation measures, and the surface temperature is very high. Of course, the most important thing is that there is no observation window. Once there is a problem with the gas turbine, you can only open the working door and go inside to troubleshoot. In some cases, it may be counterproductive. For example, once an internal fire breaks out, the only way to extinguish the fire is to open the working door, but once it is opened, the flames may jump into the engine room. Therefore, we designed a new cover based on the experience of the LM2500 gas turbine."
Lao Maozi has never paid attention to ergonomics. You can tell by looking at the mess of their turbine rooms. In comparison, the United States is very advanced, so now, the gas turbine R&D unit combines the best of Chinese and Western directors to carry out Some improvements.
This cover is the first step.
“We used the box-type cover of the LM2500 gas turbine to cover the entire gas turbine. At the same time, the cover was laid with heat-insulating and noise-reducing materials, which effectively reduced the noise and temperature of the turbine room. At the same time, an observation window was set up on the box. The window makes it easy to observe the operation of the gas turbine, and in order to make troubleshooting easier, we also installed a lighting system inside."
Everyone nodded. These small changes will bring great benefits to the engineers. These are all plans worthy of encouragement.
"Then there is the base. There are many problems with the base. For example, there are no guide rails on the base. If the gas turbine needs to be repaired, the gas turbine needs to be lifted out. This is very inconvenient. We have installed guide rails on the base, which require maintenance. At that time, it can be moved directly through the guide rail. At the same time, the most important improvement is the exhaust pipe. The previous exhaust pipe was prone to aging, causing hot air to leak into the engine room. We have now integrated the exhaust pipe into the base, so that it no longer We need exhaust pipes made of rubber, which completely solves the aging problem."
These improvements are all based on the problems that occur in the use of current gas turbines, making the use of gas turbines more reliable.
“Yes, you have always considered the users and are our navy’s most trusted power provider.” Wu Shengli nodded.
"We will definitely work hard. Our GT-25000 gas turbine can be further improved, but the maximum power increase to 30 megawatts is already the limit. So now, we are very much looking forward to the next D-18T aeroderivative aircraft project. When this project is completed, our navy will have 40-megawatt gas turbines, so that our 10,000-ton large drives can continue to use alternative diesel power."
Wen Xueyou is more confident about the future.
General Qin has already said that the Navy will definitely build a 10,000-ton large drive in the future. However, how to solve the power problem of this 10,000-ton large drive?
The original idea was to use four gas turbines, two for low speed and four for high speed, thus forming full combustion power. This combination can provide ample power, but it will also lead to high costs, especially during cruising. , using a gas turbine will result in excessive fuel consumption.
However, since four gas turbines have been installed, it is impossible to install more diesel engines. So how to solve the problem?
Now, the problem has been solved. Two 40-megawatt gas turbines can be used to drive a 10,000-ton engine. The diesel engine can be used for normal cruising, which is equivalent to an enlarged version of the power system of the current 052 destroyer. This system is now mature. Yes, continuing to use it is the best choice.
Wen Xueyou has already begun to think about the future.
"Speaking of gas turbines, other domestic units are also developing them." At this moment, a leader thought of something: "For example, relevant units are developing related gas turbines based on the turbojet-14 and turbofan-10. .”
For warships, gas turbines that start quickly, increase speed quickly, and have sufficient power are the best choices. Therefore, domestic attempts to modify aviation engines into gas turbines have been carried out in the early years. The engines of Yun-10 and H-6 have been modified, but because All kinds of problems ended up in vain. In the 1980s, domestic gas turbines were also built based on the Spey engine, but the power was only 10 megawatts. After passing the prototype appraisal in 1993, there was no further development.
However, relevant domestic institutions are still not discouraged and continue to make persistent efforts. However, aeroderivative aircraft need mature engines. Now, domestically produced engines are not yet mature. This is equivalent to running before you have learned how to walk.
Especially the turbojet-14, it is said that the J-7 and J-8 will be refitted. However, who would dare to use an engine whose parts are flying in the sky?
As for the Turbofan 10, I don’t know how far it has been developed. Anyway, the stealth aircraft manufactured by the Mingzhou Group still uses the Turbofan-15 copied from the R-79 technology obtained from Lao Maozi.
"Two years ago, the relevant units modified the QD70 gas turbine on the turbofan engine with a power of 7 MW. They plan to further develop the model and the power will reach about 18 MW." The leader continued: "If this When this type of gas turbine is mature, can our frigates also use diesel-fuel alternating power?"
The power is not enough, so it is impossible to use it on a destroyer. It is almost enough to be used on a 4,000-ton frigate. After all, the power is almost the same as the old LM2500 gas turbine.
“Forget it about frigates. Our frigates focus on economy. Gas turbines are too expensive. However, if they are really mature, they may be used in our air-cushion landing craft.” Qin Tao said.
He is not familiar with the domestic technical level, so he doesn’t know whether this thing is mature or not. He just knows that the main warships of the Navy have never used self-developed gas turbines, and all use improved Ermao technology.
Now, there is no need to say anything more. Anyway, the Navy will not pay for this D-18T improved gas turbine project. It is entirely done by the Mingzhou Group itself. When it is completed, the Navy will definitely purchase it. Not only for personal use, but also for export. Those aircraft carriers of 20,000 to 30,000 tons can also use gas turbines of this level.
After talking about the gas turbine project, everyone was already hungry, but the meeting was not over yet.
“Mr. Qin, did you just talk about the helicopter hangar?”
"Yes, there are still some uncertainties in the design of our warship, that is, the combination of helicopters. If the Ka-27 is used, the existing hangar will be enough. If it is equipped with our new helicopter, the tail must be If it is lengthened by four to five meters, the displacement will be further increased by several hundred tons."
This is the difference between 052D and 052DL. The former is equipped with the Ka-27, and the hangar is very high, but it does not need to be too long. The latter is equipped with the Z-20, so the hangar must be elongated, and the flight deck must also be elongated. In this way, when the front does not move, the tail must be lengthened. The displacement has increased rapidly, but it can still be controlled within 8,000 tons.
"Helicopters are a big problem. Now the Air Force attaches great importance to it. A ten-ton general-purpose helicopter project has been approved, but research and development still needs a long way to go. In particular, we do not have qualified engines." A leader said.
At the beginning, Qin Tao had discussed this issue with Boguslayev and tricked the other party into joining forces to jointly develop an engine for ten-ton helicopters. Boguslayev was very interested, but nothing happened after that!
Even if a gas turbine is currently being developed based on the D-18T, that type of engine has not been developed.
Qin Tao knew that the target he required was too high, which frightened Boguslaev. He knew that it was too difficult to develop an engine of that level, and a huge amount of money had to be invested. If the research and development failed, , then they are completely screwed.
In contrast, the technical difficulty of tinkering with gas turbines based on the D-18T is much smaller.
Now, let’s talk about the engine again. This thing is always a hurdle that cannot be bypassed.
“When it comes to helicopter engines, Maple Leaf Country is the most professional. Can we import engines from Maple Leaf Country first?” Someone suggested.
“No, we must develop our own key domestically produced equipment.” Qin Tao said, “Maple Leaf Country is even more unreliable. I’ll think of another way.”
We can only continue to urge Ermao. If Motorsic Company wants to develop and grow, it must be bold and engage in research and development. Archaeology will not work.
“Let’s use the K-27 as the carrier first. When our ten-ton general-purpose helicopter matures in the future, it will not be too late to improve it.” Wu Shengli said.
Qin Tao nodded. The meeting was finally over. Looking at his watch, it was already 4:30 in the afternoon!
"Sparing lunch, let's just have dinner." A leader said: "However, considering that our modified warship can have more powerful combat effectiveness, it is worth skipping a meal!"
“Leaders, wait, there is one last little question.” Qin Tao said: “Should our modified warship have a model number?”
“Do I need to mention the model number? 052D! Do you want to get a new one, such as 055?”
Having both B and C, type D will definitely be next! There is nothing to say about this.
Qin Tao nodded: "Well, let's go with D. The 055 can't be used, it has to be reserved for our future 10,000-ton large-scale drive."
The meeting has finally ended. This meeting discussed the comprehensive upgrade of 052C. Although it is not as exciting as the original air defense ship bidding, it is still of great significance. It represents that the navy's equipment will be improved to a higher level!
Everyone’s stomachs were growling with hunger. After entering the canteen, no one was devouring their food. Everyone was chatting while eating, and the content of the conversation was still about the development of naval equipment.
“Mr. Qin, you are cooperating with Motor Sich Company to develop a 40-megawatt gas turbine. Once this project is successful, it should be the world’s largest naval gas turbine, right?” a leader asked.
“Yes, it should be the largest in the world.” Qin Tao said.
The largest British naval gas turbine is the MT30 gas turbine. The maximum output power of this gas turbine can reach 40 megawatts. However, its development was only after the new millennium, and its delivery was only after 2010. Now, our side This project is earlier than MT30, and with the ingenuity and hard work of the Eastern people, it will definitely be developed and matured earlier.
"When this gas turbine is successfully developed, our navy's 10,000-ton destroyers will have reliable power." Wu Shengli said that he was also very satisfied with this project. After all, 055 has not yet come out, and four The combination of two gas turbines is definitely not as good as two gas turbines and two diesel engines. The reason is also very simple: when the diesel engine is used for cruising, the fuel consumption will be lower.
"In addition to destroyers, the aircraft carriers sold by our Mingzhou Group can also use this kind of gas turbine. If the Navy wants to build amphibious assault ships in the future, it can also use this power. When the Navy enters the era of nuclear-powered aircraft carriers, we The boilers will be completely eliminated." Qin Tao said.
Now, the aircraft carriers being built by the Navy, as well as the next one or two, will continue to burn boilers. After all, the maturity of aircraft carrier nuclear reactors does not happen overnight. Although domestic research has begun, it will definitely take many years. Of course, if the next If the ship can enter the nuclear power era, it will naturally be better.
"The method of burning boilers has long been outdated. We should eliminate it completely." Wu Shengli nodded: "The navy's ships are becoming more and more modern. Let's toast to the construction of a modern navy!"
cheers!
Everyone's hearts were filled with excitement, as if they had seen the powerful navy of the motherland.
"The 052D research meeting has ended. Next, Mingzhou Group will report the detailed design plan as soon as possible and submit it to the Navy for review." Wu Shengli continued: "When the fourth 052C is launched, the construction of our 052D will begin. ”
Qin Tao nodded: "Yes, we will go all out. In a few days, we will formally sign a gas turbine research and development and production contract with Ermao in the capital. If the navy leaders have time, can they attend our contract signing ceremony?"
“Of course, we must go and support it!”
Ermao arrived earlier than expected. On the second day after the naval meeting, Boguslayev, the head of Motorsich Company, came to the capital. In addition to his granddaughter Zamotayeva, he also brought Another person came.
"Qin, let me introduce to you. This is the head of the Progress Design Bureau, Fidel Mikhailovich Muravsenko." Boguslaev pointed to the person next to him and said: "He used to be A student of Ulming also won the Medal of Heroes.”
Progress Design Bureau, code-named 478 Experimental Design Bureau, was named Ivchenko "Progress" Design Bureau after the then chief designer and academician A-G Ivchenko in 1945. However, unlike other design bureaus named after their first designers, its first designer was Ulming. This gentleman had a high reputation and his subordinates were proud of being his students. Even though Urmin was only in school by name and never attended classes.
Motor Sich Company is just a production factory. They can export the product lines they have mastered the production process to the East and come to the East to cooperate in production. However, it is impossible for them to research and improve an existing engine.
This project needs to be completed by the Progress Design Bureau, so now Boguslayev has invited the head of the Progress Design Bureau to come over.
Looking at the old man in front of him, Qin Tao stretched out his warm hands: "Mr. Muravsenko, welcome to the East. In the era of the Red Empire, the Progress Design Bureau was a leader in the field of aero-engine design. We are here to work with you." I am proud of your cooperation.”
Muravsenko smiled bitterly and shook his head: "Mr. Qin, in the era of the Red Empire, we were indeed very powerful. However, since the collapse of the Red Empire, we have not had any new products. Over the years, some experience in our design bureau has Rich designers have gone to the West, and our design capabilities are not what they used to be."
Qin Tao was a little surprised. Is there such a straightforward old man? Normal negotiations are all about boasting about oneself, but now, the other party is actually complaining about it? Aren't you afraid that you will doubt the opponent's strength?
“So, Mr. Qin, if this project is handed over to us to design, we need to charge a certain fee.” Muravsenko said.
The previous part is just a foreshadowing, for what follows.
On Mao's side, the design bureau and factory have been combined to form a scientific research and production consortium, but there is no such thing here. Motorsich Company was pulled together by Boguslaev, and all Zaporizhia's The aircraft engine manufacturing plants were all grouped together, but the Progressive Design Bureau was not included.
So, the Progressive Design Bureau has had a very hard time over the years.
"Mr. Muravsenko, Mr. Boguslaev and I have already talked. We plan to form a special gas turbine research institute near Genghis Khan. We will not leave the entire design project to you. We will It’s joint research and development,” Qin Tao said.
Will the other party have any misunderstanding? Do you think you want to ask them to design and then pay them a design fee?
I made it very clear, joint research and development!
"Yes, Qin, I know." Boguslaev said: "Our design work can be placed near Tianjiao Airlines, and the next design work will be supported by us together. However, the Progress Design Bureau has not been there for a long time. Salaries have started, and if their engineers want to come to the East, they need to make up for their previous wages.”
Qin Tao nodded: "Then how many do you need?"
"With about two million U.S. dollars, we can send a hundred engineers here." Muravshchenko said: "Mr. Qin, the money we need is additional expenditure. Next, all the expenses of these engineers in the East, They all need to be provided by you, and because these people are sent by our design bureau, our design bureau hopes to get an extra amount of money to maintain the daily operation of our design bureau. This does not need to be too much, there are ten per year. Ten thousand dollars is enough.”
This guy came to ask for money. Because they had little income, they took this opportunity to treat Mingzhou Group as a fat sheep!
"Mr. Qin, the Progressive Design Bureau is in a difficult situation now. As long as it accepts this funding, it will be able to develop and get on the right track." Boguslayev said: "They can design more advanced aero engines and gas turbines, and they can also It means that we can produce more advanced equipment. This money should be nothing to your Mingzhou Group, right?"
Boguslaev is still full of expectations for Qin Tao's generous donation. Mingzhou Group is not short of money, and it is just drizzle to help the Progress Design Bureau tide over the difficulties.
"Boguslaev, my friend, our friendship is friendship and business is business." Qin Tao said: "We invite engineers from the Progressive Design Bureau to work, and of course we will pay them. However, the hole before was not ours. Damn it, we have no obligation to fill this hole for you."
Qin Tao actually refused!
Muravshchenko’s face was a little ugly.
After the collapse of the Red Empire, their design bureau immediately fell into a desperate situation. Over the years, he has been working hard and supporting himself. Many times, he has faced the colleagues who left and the colleagues who stayed but could not pay their salaries. , Muravsenko wanted to take out the pistol in his desk and point it at his temple.
Once, their design bureau could be ranked among the top five in the world. How did it fall to this point now?
“Boguslaev, my friend, your Motorsich Company needs design capabilities. Why don’t you merge the Progressive Design Bureau to form a scientific research and production consortium, just like what has been completed by Da Mao?”
Hearing Qin Tao's question, Boguslaev smiled bitterly: "Mr. Qin, after the collapse of the Red Empire, our Motor Sich Company has only been able to maintain its existence over the years. How can we maintain the Progress Design Bureau?" Expenses? If we continue to carry the burden of the Progressive Design Bureau, our Motorsic Company may not be able to survive."
They are different from Da Mao. After all, Da Mao can sell aircraft. For example, by selling Su-27, Rulica-Saturn Design Bureau has been living a very prosperous life.
Although Motorsich Company is very good at making engines, their domestic Antonov Design Bureau is not strong enough and cannot sell a single aircraft. Who will the engines they build be given to? Da Mao? Da Mao can also produce it himself, so there is no need to use Er Mao.
“If this is the case, then I will have a suggestion.” Qin Tao said: “It can solve the dilemma of the Progressive Design Bureau, and even allow the Progressive Design Bureau to develop.”
“President Qin, please speak.” Muravshchenko was full of expectations.
"You are now short of two million US dollars, and we at Mingzhou Group can give it to you. However, the two million US dollars must be invested in shares. We are not pursuing absolute controlling rights. Just give us 49% of the shares. Qin Tao said: "As long as we hold shares in your design bureau, we will be one. Of course we will not watch the Progress Design Bureau collapse."
With this good opportunity, how could Qin Tao miss it?
