MTL - Warship of Great Power-Chapter 738 Hardworking progressive design bureau

In fact, the big guy has already known how strong the motivation for this type of change is, so if you keep talking about motivation here, it is not what the leader wants to hear. Wen Xue also knows it. After a few words, he turned 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 engine room is relatively high, 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 enter the interior to troubleshoot. In some cases, it may be counterproductive. For example, once a fire breaks out inside, the only way to put out the fire is to open the working door, but once opened, it may cause flames to jump into the engine room. Therefore, we designed a new cover based on the experience of the LM2500 gas turbine.”

Old Maozi has never paid much attention to ergonomics. You can tell by looking at the mess in their engine rooms. In comparison, the United States is very advanced. So now, the gas turbine research and development unit has integrated Chinese and Western directors and carried 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 engine room. The window is convenient for observing the situation of the gas turbine when it is running, and in order to facilitate troubleshooting, we also installed a lighting system inside."

  Everyone nodded, these small changes will bring great benefits to the engineers, and these are plans worth encouraging.

"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 hoisted out. This is very inconvenient. We have added guide rails to the base, which needs to be maintained. At the same time, the most important improvement is the exhaust pipe. The previous exhaust pipe was easy to age, causing hot air to leak into the engine room. Now we integrate the exhaust pipe into the base, so that there is no longer Exhaust pipes made of rubber are needed, and the aging problem is completely solved.”

  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.

   "That's right, you have always considered users and are the most trusted power provider of our navy." Wu Shengli nodded.

"We will definitely work hard. Our GT-25000 gas turbine can be further improved, but the power can be increased to 30 megawatts at most, which is already the limit. So now, we are very much looking forward to the next D-18T aeroderivative project, After this project is completed, our navy will be able to have a 40-megawatt gas turbine, so that our 10,000-ton large drive can continue to use diesel-fuel alternative power."

  Wen Xueyou is more confident about the future.

  President Qin has already said that the Navy will definitely build a 10,000-ton large drive in the future, but how to solve the power 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, so as to form an all-combustion power. This combination can provide abundant power, but it will also lead to high cost, especially in the cruising state. , the use of gas turbines can lead to excessive fuel consumption.

  However, four gas turbines have already been installed, so it is impossible to install diesel engines, so how to solve it?

Now, the problem has been solved. Two 40-megawatt gas turbines can drive a large 10,000-ton drive. Diesel engines are used for normal cruising, which is equivalent to the 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 started to imagine the future.

"Speaking of gas turbines, other units in our country are also developing." At this moment, some leaders thought of something: "For example, relevant units are developing related gas turbines on the basis of WS-14 and WS-10." .”

For warships, gas turbines with fast start-up, fast speed-up, and sufficient power are the best choice. Therefore, domestic attempts to modify aero-engines to gas turbines have been carried out in the early years. The engines of Yun-10 and H-6 have all been modified, but because All kinds of problems ended without a problem. In the 1980s, domestic gas turbines were produced on the basis of the Spey engine, but the power was only 10 megawatts. After passing the prototype appraisal in 1993, there was no follow-up.

  However, relevant domestic agencies are still not discouraged, and continue to make persistent efforts. It's just that the aero-derivative needs a mature engine. Now, the domestically produced engines are not yet mature, which is equivalent to running without learning how to walk.

  Especially the WJ-14, it is said that J-7 and J-8 will be refitted, but who dares to use an engine that flies parts in the sky?

  As for Turbofan 10, I don’t know how far it has been developed. Anyway, the stealth machine manufactured by Mingzhou Group uses the Turbofan-15 imitated by R-79 technology obtained from Lao Maozi.

"Two years ago, the relevant units modified the QD70 gas turbine on the turbofan ten engine, with a power of 7 megawatts. They plan to further develop the model, and the power will be about 18 megawatts." The leader continued: "If this This kind of gas turbine is mature, can our frigate also use diesel-fuel alternating power?"

  The power is not enough, it is impossible to use it for destroyers, and the use of 4,000-ton frigates is almost the same. After all, the power is almost the same as that of the old LM2500 gas turbine.

   "Forget about the frigate. Our frigate is mainly economical. It is too expensive to use gas turbines. However, if it is really mature, it may be used on our air-cushion landing craft." Qin Tao said.

  He is not familiar with the level of domestic technology, so he doesn't know whether this thing is mature or not. He just knows that the main naval warships have never used self-developed gas turbines, and all of them have been improved by 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 completely done by Mingzhou Group itself. Not only for personal use, but also for export. Those aircraft carriers with a capacity of 20,000 to 30,000 tons can also use gas turbines of this level.

   After talking about the gas turbine project, everyone is already hungry, but the meeting is not over yet.

   "Mr. Qin, did you just talk about the issue of the helicopter hangar?"

"Yes, there are still some uncertainties in the design of our warship, that is, the matching of helicopters. If Ka-27 is used, the existing hangar will be fine. If it is equipped with our new helicopter, the tail must be If it is extended by four or five meters, the displacement will be further enlarged by several hundred tons."

   This is the difference between 052D and 052DL. The former is equipped with Ka-27, the hangar is very high, but not too long, the latter is equipped with Zhi-20, the hangar must be elongated, and the flight deck must also be elongated, so that the tail must be lengthened when the front is not moving. The displacement has soared, but it can still be controlled within 8,000 tons.

"Helicopters are a big problem. Now the Air Force attaches great importance to them. The ten-ton general-purpose helicopter project has been approved, but the research and development still needs a long way to go. Especially, we don't have qualified engines." A leader Said.

  Back then, Qin Tao had discussed this issue with Boguslayev, and he tricked them into joining forces to jointly develop an engine for a ten-ton helicopter. Boguslayev was very interested, but there was no further information after that!

  Even if the gas turbine is now developed on the basis of the D-18T, that engine has not been developed.

Qin Tao knew that it should be that the indicators he asked for were too high, which frightened Boguslayev. He is self-aware. It is too difficult to develop an engine of that level, and he has to invest a lot of money. In case the research and development fails , then they are completely finished.

   In contrast, the technical difficulty of tinkering with gas turbines on the basis of D-18T is much smaller.

   Now, let's talk about the engine again, which is always a hurdle that cannot be bypassed.

   "When it comes to helicopter engines, Maple Leaf Country is the most professional. Can you import engines from Maple Leaf Country first?" Someone suggested.

   "No, we must develop our own key domestic equipment." Qin Tao said, "Maple Leaf Country is even more unreliable. I'll think of a way."

  I can only continue to urge Ermao. If Motor Sich wants to grow, it must have courage. Research and development must always be archaeological.

   "Let's take the K-27 as the target first. When our ten-ton general-purpose helicopter matures, it won't 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!

   "Lunch is saved, let's have dinner directly." A leader said: "However, considering that our remodeled warship can have stronger combat effectiveness, it is worth eating one less meal!"

   "Leaders, wait, there is one last small question." Qin Tao said, "Our modified warship should have a model, right?"

   "Does the model need to be mentioned? 052D! Do you want to start a new one, such as 055?"

  I have both B and C, and the next one must be D type! There is nothing to say about this.

  Qin Tao nodded: "Well, let's go to D. The 055 can't be used, and we have to save it for our future 10,000-ton large drive."

  The meeting is finally over. This meeting discussed the overall upgrade of 052C. Although it is not as exciting as the original air defense ship bidding, it is still of great significance. It means that the navy's equipment will be upgraded to a higher level!

  052D destroyer will also be born!

  Everyone’s stomachs were already growling with hunger. After entering the cafeteria, no one devoured the food. The big guys chatted while eating, and the content of the chat was still the development of naval equipment.

   "President Qin, you are cooperating with Motor Sich 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 marine gas turbine used by the British is the MT30 gas turbine. The maximum output power of this gas turbine can reach 40 megawatts. However, its development is already after the new millennium, and it will be delivered after 2010. Now, our own side This project is earlier than MT30, and, with the ingenuity and assiduous spirit of the oriental people, it will definitely be developed and matured earlier.

"When this gas turbine is successfully developed, our navy's 10,000-ton destroyer will have reliable power." Wu Shengli said, he is also very satisfied with this project. After all, the 055 has not yet come out, and, four The combination of two gas turbines is definitely not as good as two gas turbines plus two diesel engines. The reason is also very simple: the diesel engine is used for cruising, and 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 an amphibious assault ship in the future, it can also use this kind of power. When the navy enters the era of nuclear-powered aircraft carriers, we boilers will be completely eliminated," Qin Tao said.

Now, the aircraft carrier being built by the Navy, and one or two subsequent ships, 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 It would be even better if the ship can enter the age of nuclear power.

   "The way of burning boilers has been outdated for a long time, and we should completely eliminate it." Wu Shengli nodded: "The navy's ships are becoming more and more modern. Let's make a toast to the modernization of the navy!"

cheers!

  Everyone was excited, as if they saw 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 approval." Wu Shengli continued: "When the fourth 052C ship is launched, the construction of our 052D will begin. gone."

  Qin Tao nodded: "Yes, we will go all out. In a few days, we will formally sign a gas turbine R&D 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 to support!"

The arrival of Ermao was earlier than expected. On the second day after the naval meeting, Boguslayev, the head of Madasich, came to the capital. In addition to his granddaughter Zamotayeva, he also brought Another person came.

"Qin, let me introduce you. This is the head of the Progressive Design Bureau, Fidel Mikhailovich Muravsenko." Boguslayev pointed to the people around him and said, "He used to be A student of Ulmin, who has also won the Hero Medal."

  Progressive Design Bureau, code-named 478 Experimental Design Bureau, was named Ivchenko "Progressive" Design Bureau after the then chief designer and academician A-G Ivchenko in 1945. However, unlike other design bureaus named after the first designer, its first designer is Urmin. This gentleman has a high reputation, and his subordinates are all proud of his students. Even if Wu Erming is only a name in the school and has never attended a class.

   Motor Sich is just a production plant. They can export the product line that they have mastered the production process to the East, and come to the East to cooperate in production. However, they cannot research and improve an existing engine.

  This project needs to be completed by the Progressive Design Bureau, so now, Boguslayev has invited the person in charge of the Progressive Design Bureau.

Looking at the old man in front of him, Qin Tao stretched out his enthusiastic hands: "Mr. Muravsenko, welcome to the East. The Progress Design Bureau was a leader in the field of aero-engine design in the era of the Red Empire. We are proud of your cooperation."

Muravsenko smiled wryly and shook his head: "Mr. Qin, we were indeed very powerful in the era of the Red Empire, but since the collapse of the Red Empire, we have not released any new products. Over the years, some experience in our design bureau Rich designers have gone to the West, and our design capabilities are not as good as before.”

  Qin Tao was a little surprised. Is there such a direct old man? In normal negotiations, you want to blow yourself up to the sky, and now, the other party is actually complaining to you? Aren't you afraid that you doubt the opponent's strength?

   "So, Mr. Qin, if this project is entrusted to us to design, we need to charge a certain fee." Muravsenko said.

  The front is just a foreshadowing, he is for the next words.

On Da Mao's side, the design bureau and the factory have been combined to form a scientific research and production complex, but there is no Lao Maozi here. The production plants of aero-engines were grouped together, but the Progressive Design Bureau was not included.

  So, Progressive Design Bureau has had a tough time these years.

"Mr. Muravsenko, I have already talked with Mr. Boguslayev. We plan to form a special gas turbine research institute near Genghis Khan Aviation. We will not hand over the entire design project to you. We will It is a joint research and development." Qin Tao said.

  Will the other party misunderstand? Think you want to invite them to design, and then give them design fees?

   I made it very clear, joint research and development!

"Yes, Qin, I know." Boguslayev said: "Our design work can be placed near Genghis Khan Aviation, and the next design work will be supported by us together. However, the Progressive Design Bureau has been absent for a long time. The wages are paid, and their engineers want to come to the east, so they need to make up their previous wages."

  Qin Tao nodded: "Then how much do you need?"

"About two million dollars, we can send a hundred engineers here." Muravsenko said: "Mr. Qin, the money we need is an additional expense. Next, all the expenses of these engineers in the East, They all need to be provided by you, and because these people are all sent by our design bureau, our design bureau hopes to get an extra sum of money to maintain the daily operation of our design bureau. Ten thousand dollars would suffice."

   This guy came to ask for money, because they have no income, so they took this opportunity to treat Mingzhou Group as a fat sheep!

"President Qin, the Progressive Design Bureau is in a difficult situation now. As long as they accept this funding, they will definitely be able to develop and get on the right track." Boguslayev said: "They can design more advanced aero engines and gas turbines. It means that we can produce more advanced equipment. This money should be nothing to your Mingzhou Group, right?"

   Boguslayev is still full of expectations for Qin Tao's generous donation. Mingzhou Group is not short of money, and helping the Progressive Design Bureau to tide over the difficulties is completely drizzle.

"Boguslayev, my friend, our friendship is friendship, and business is business." Qin Tao said: "We invite engineers from the Progressive Design Bureau to work, of course we will pay, but the previous hole is not ours. Digging, we have no obligation to fill this hole for you."

  Qin Tao actually refused!

  Muravsenko's face was a bit 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 struggling to support him. Many times, he faced the colleagues who left and the colleagues who stayed but could not pay. Muravsenko really wanted to take out the pistol from his desk and point it to his temple.

   In the past, their design bureau could be ranked among the top five in the world. Now, how did it fall to this point?

   "Boguslayev, my friend, your Motor Sich company needs design capabilities. Why don't you merge the Progressive Design Bureau to form a scientific research and production complex, just like what Da Mao has already done?"

Hearing Qin Tao's question, Boguslayev smiled wryly: "Mr. Qin, after the collapse of the Red Empire, our Motor Sich Company has just been able to maintain it for these years. How can we maintain the progressive design bureau? Expenses? If we carry the burden of the Progressive Design Bureau, then our Motor Sich company may not be able to sustain it."

  They are different from Da Mao. After all, Da Mao can sell aircraft. For example, relying on the sale of Su-27, the life of Rurika-Saturn Design Bureau is very nourishing.

  Although Motor Sich is very powerful in making engines, their domestic Antonov Design Bureau is not strong enough. They can’t even sell a single plane. Who will they give the engines to? Big hair? Da Mao can produce it himself, so there is no need to use Er Mao.

   "If this is the case, then I 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."

   "Mr. Qin, please speak." Muravsenko was full of expectations.

"You are currently short of two million dollars, and Mingzhou Group can give it to you. However, the two million dollars must be invested in the form of shares. We do not pursue absolute controlling rights, just give us 49% of the shares. "Qin Tao said: "As long as we hold the shares of your Design Bureau, then we will be one. Of course, we will not watch the Progressive Design Bureau collapse."

   Given this great opportunity, how could Qin Tao miss it?
