Chapter 599 Gas Turbine Comparable to MT30

"Our new bomber project has been approved by the superior." That night, Mr. Lin, who came from the capital, met Qin Tao and chatted with him immediately: "The superior has decided to fully launch the mapping of the Tu-22M bomber. The imitation work is expected to have more than 100 bombers in total.”

   "The air force or the total?" Qin Tao asked.

   "For the Air Force, the Navy still can't find funds for research and development." Elder Lin said: "Now our Air Force is looking forward to this bomber and hopes to use it to completely replace our existing Tu-16."

   No wonder no one came from the Navy. They have been working on it for a long time, trying to get rid of the R&D funds of the Air Force.

After all, the Tu-16 is old. Now that there are more advanced bombers, the air force is very urgent. As for the navy, it must be urgent, but the navy has no money. After repairing those second-hand Tu-22Ms, there is There are about ten H-6Js for temporary use, and we will talk about it later when we have money.

"For us, the production of the airframe is not too difficult. The most important thing is the engine." Lin Lao said: "This project is of great importance. If the engine can be imitated, the future model without afterburner may still be able to use it." On our transport aircraft and other aircraft, the next-generation stealth bomber we are going to develop may also be used."

  Qin Tao nodded.

  He is actually not very optimistic about the Tu-22M. He thinks it is enough to drag out a few to scare people. The most important thing is to develop a stealth bomber, but since the navy and air force have such an urgent need, he will not pour cold water on it.

"We have the information we got from the Kuznetsov Design Bureau, and a group of engineers. With these as the backbone, we can still organize a research and development team. We use the 430 factory as the designated research and development factory. We hope that the 430 factory will not be lost. Chain, after the full localization of Turbofan 9 is completed, the project of Turbofan 16 will be launched."

   "Of course, we will go all out." Jiang Lao nodded: "It's just that, Mr. Qin, if you push an old man to be the chief teacher, I'm afraid some people will not be convinced."

"Unconvinced? In each branch of our Mingzhou Group, there are a large number of old Maozi who are the chief teachers, including our fighter jet project, and the old Maozi is also the leader. If anyone disagrees, let him go. If you don't agree, Then let's change to another factory to do research and development, we don't have the skills, and the pink eye disease is not small."

  Elder Jiang stopped immediately.

Mr. Lin nodded: "That's right, the 430 factory has always complained that there is no project. Now that the project is here, if you still want to pick and choose, then you deserve to have nothing to eat! Huh, after so many years of imitation, Spey has not completed 100% Now that we have a new task, are you still not convinced? Mingzhou Group is already planning an aircraft factory, and at worst, build an engine factory! Lao Jiang, pass on my words and let them be honest. , do research obediently, if anyone dares to make small moves and delay this project, be careful, I will spank his ass!"

  Jiang Lao nodded: "Okay, I understand. This project is related to the development of our 430 factory. No matter who it is, they must obey the arrangement unconditionally. If someone makes a move, I will be the first to let them go!"

   This night, many people are destined to have no sleep, and Sobolev did not fall asleep either. After thinking about it carefully, he always felt that something was wrong, but he couldn't tell it.

  After the meeting, Elder Lin specified that he would share a room with Qin Tao, lying on the bed, and the two were chatting.

   "Taozi, your arrangement is just like Water Margin. Whoever Liang Shan likes, he will plant and frame him, so that he can't live a comfortable life before, and can only become a bandit."

   "Mr. Lin, you don't like Liang Shan?" Qin Tao said with a smile: "Many people regard them as heroes!"

   "Heroes? There may be a few of them, such as Lin Chong, the leopard head, but most of them are villains who kill innocent people indiscriminately."

   "Then who do you think I am like?"

   "You? Song Jiang, on the surface you seem kind-hearted, but in reality you are the most sinister and cunning."

"Thank you for the compliment."

the next day.

"First of all, let's welcome Da Mao's guests with warm applause. From now on, we will be comrades, and we will fight side by side!" Qin Tao presided over the meeting himself. Considering that Lao Maozi can't understand Chinese for the time being, so, Qin Tao used Russian directly, and then Xu Zhengyang translated it.

   There was a burst of applause below.

"Now, we would like to introduce our turbofan sixteen engine project, which is a three-rotor turbofan engine; the weight of the engine is 3400 kg, the maximum thrust of a single unit is 137.3 kN, the afterburning thrust is 226.5 kN, and the thrust-to-weight ratio 7.35..."

   These words made Sobolev a little curious, these parameters are almost exactly the same as the Nk-32 engine!

"This engine is related to our large aircraft project. If the afterburner is removed, it can be used as an engine for a large aircraft. With the afterburner installed, it can also be used as an engine for a bomber. It is of great significance to us. Thanks to the big hair The arrival of technical personnel can make our project progress by leaps and bounds."

  When he heard Qin Tao's words, Sobolev felt even more uneasy.

   "Now, let's take a look at the structure diagram."

   Waiting until the slide projector played out the structure diagram, Sobolev felt deep in his mind, and suddenly, there was a thunderclap, and he understood, he understood everything.

   I don't know what method Mr. Qin used to get back the information on the Nk-32 engine! And it is conceivable that the outside world will definitely think that these designers from our own side have brought them back. If they dare to return to Da Mao in the future, they will definitely be arrested as leakers! Therefore, in addition to doing research here with peace of mind, they will never be able to do anything else.

  I can’t go back even if I have a home!

  Thinking of this, Sobolev's heart fell to the bottom. Why did he follow Mr. Qin to the east when he was confused at the beginning? However, there is no regret medicine in this world.

   This engine is indeed very important to Dongfang. The most lacking thing in the development of various aircraft in Dongfang is the engine, and the Nk-32 is known as the most advanced engine for large aircraft in the world, and it is also very good.

After removing the afterburner, there is still a thrust of more than 100,000 Newtons, which is stronger than the power of the D-30K. It is cool when used on a transport aircraft, and the afterburner thrust is more than 200,000 Newtons, which can push the bomber to go supersonic. flight.

   If we develop the H-20 in the future, we will have qualified engines to use it!

  Thinking of this, Qin Tao also felt a little emotional, another shortcoming has been made up for!

  Although the H-20 of the later generations was developed on the basis of the turbofan ten-core machine, now that there is such a special project, it can be used directly.

   "President Qin, what kind of aircraft is this turbofan sixteen used to assemble?" Sobolev couldn't help but ask.

   "Our H-6 modified aircraft. It is your domestic Tu-16." Qin Tao said: "If we want to upgrade our bomber, we must have more advanced power."

  A modified version of Hong Liu? Sobolev still doesn't believe it, does the modification of the H-6 use this kind of engine? However, since Boss Qin said it, there should be no problem, right?

  He trusted Qin Tao until a few years later when he saw the plane, his eyes fell out of surprise. Do you call this plane a modification of the H-6? This is obviously a modification of the Tu-22M!

   "By the way, please feel at ease to work here, we are trying to find a way to take over your family." Qin Tao thought of something and continued.

family?

  Sobolev felt a warm current in his heart. If his family came over, there would be nothing to say, and he could work here with peace of mind in the future.

"I don't know how the materials and processes are progressing here. I think that if there are no accidents, we should be able to complete the research and development of this engine within five years." Since Sobolev is the chief designer, he must For the military order, he is very familiar with this engine, and there is no problem with the design. The main thing is how to process it. In the past five years, he has to study the processing technology.

   "Okay, then I'm looking forward to your results. Five years later, when this engine is developed, the superior will hold the most solemn commendation meeting for you, and will also give you a large bonus!"

   After making some promises, the meeting was over, and the 430 factory dispatched a group of technicians to join the research and development unit to jointly develop this engine.

  Mr. Lin didn't speak during the whole process. It was enough to leave it to Qin Tao. When the meeting was over and he came to the office, Mr. Jiang spoke again.

   "Once the development of this engine is completed, it will become the most advanced aero engine in our country. If we use the technology of this engine to develop a gas turbine, do you know if the Navy has this demand?"

  Deriving gas turbines from aero-engines is the most common practice in the West. The gas turbines modified by Spey have supported the fleets of many countries. The LM2500 in the United States is also modified from aero-engines.

The 430 factory has been working hard to develop in this direction. It used to have the idea of ​​​​refitting the gas turbine on the Spey engine, but because the navy already had two hairs technology, it finally gave up. When the navy was working on the gas turbine, the 430 factory also participated in it. , and even imagined dominance, but had to give up in the end.

   Now, seeing the advanced three-axis aero-engine project settled here, Factory 430 has this idea again.

Seeing that Qin Tao didn't speak, Mr. Jiang continued: "Now, the British are developing the MT30 gas turbine engine, which is improved from the core engine of the three-shaft Trent800 aviation turbofan engine. It is said that the maximum output power can reach 40 Megawatts, that is, more than 50,000 horsepower. One is equivalent to more than twice the size of our current GT-15000 marine gas turbine."

The interior of the aero-engine is extremely complicated. In order to better adapt to different air flow rates, modern aero-engines are at least double-rotor, and the high-pressure area and low-pressure area have different speeds. Except for the French M53, which is still a single-rotor, there is almost no It's the second paragraph.

However, the dual-rotor cannot be completely suitable for the complex internal aerodynamics, so a three-rotor engine has appeared. The three shafts are divided into three different speeds of high, medium and low, which is more adaptable, but at the same time, the internal complexity will be greatly increased. Increase.

   So far, there is no three-rotor engine in China, and there are only a few in the world.

Nk-32 is one of them, and the output power is very large. If this kind of aero engine is used to derive gas turbines, it is not difficult to have an output power of 40 megawatts at the beginning. Ten megawatts, or even more!

  After accepting this development task, they already had this kind of idea, but whether the project can be approved depends on whether President Qin supports it.

   In this regard, Mr. Qin has the absolute right to speak. As long as Mr. Qin does not support it, they will not be able to launch this project.

   "This level of power is a bit wasteful to use on a destroyer, and it is not enough to use it on an aircraft carrier."

  Hearing what Qin Tao said, Mr. Jiang's face was slightly ugly. Doesn't Qin always support it?

  The current GT-15000 will be further upgraded to GT-25000. The output power will be increased to 20 megawatts or even higher.

  052C installed two gas turbines, and later 055 installed four. So, wouldn’t it be better to replace one with two more advanced gas turbines?

  The answer is really not appropriate.

  052C uses two diesel engines at low speeds, and switches to two gas turbines at high speeds to form diesel-random alternating power. If a more powerful gas turbine is used, then there is a problem, which propeller does this gas turbine drive? Or is it distributed to the two propellers through gear transmission?

  Used on 055, it is not suitable to change from four to two. Although it can directly drive two propellers, what about low speed?

Gas turbines are quite fuel-intensive. At low speeds, 055 only needs to turn on two engines, or even only one engine, to carry out economical cruising. If four engines are replaced by two engines, it is still very fuel-intensive to operate one engine alone. ah!

It can be used on the aircraft carrier, but the aircraft carrier is facing insufficient power. Just look at the Queen-class aircraft carrier of the British. It is equipped with gas turbines, but because of fear of cost, only two are installed. As a result, the maximum speed of the aircraft carrier is 60,000 tons. Only twenty-six verses! Domestically produced aircraft carriers can't be so tasteless.

  Mr. Jiang was already a little disappointed. Without Mr. Qin's support, it meant that their research and development of this gas turbine was meaningless. However, at this moment, Qin Tao spoke again.

   "However, if it is used on an amphibious assault ship, it will be very suitable."

The shape of the amphibious assault ship looks similar to that of an aircraft carrier, but their combat missions are different. They are not used to seize air supremacy, but to attack the ground. Therefore, the straight flight deck is used to take off and land helicopters or vertically. It can take off and land fighter jets, and can also carry equipment such as hovercraft and amphibious tanks in the dock below.

  This kind of warship has a large displacement, and the current mainstream trend has begun to match 40,000 tons, but at the same time it does not need to have the high speed of an aircraft carrier.

  So, if the high-power gas turbines developed by Factory 430 are mature, two of them can drive a 40,000-ton amphibious assault ship!

  Mr. Jiang's eyes lit up: "Mr. Qin, are you supporting our project?"

   "Old Jiang, our navy doesn't have an amphibious assault ship yet." Elder Lin reminded him.

"Not now, but there will be in the future." Qin Tao said: "We need 40-megawatt gas turbines. When we sell to foreign customers, we also need this kind of gas turbines. My personal opinion is to support the development of naval gas turbines based on this aero engine."

   "Thank you, President Qin!" Elder Jiang was excited.

   "How do I feel, the Navy is robbing our Air Force's research and development funds again." Elder Lin was a little dissatisfied: "Now the entire project's funds are paid by our Air Force, and the Navy just eats off-the-shelf."

   "Old Lin, your air force can also eat ready-made ones." Qin Tao said, "Since we're here, let's go and see the flying leopards. Maybe your air force can order a batch?"

   Air Force order Flying Leopard? Mr. Lin shook his head: "Our Air Force is waiting for the two-seater J-11 modified fighter."

According to Qin Tao's suggestion, 601 worked hard to master the production process of the J-11, and improved the J-15. After that, it should be able to develop a two-seater fighter-bomber, retaining the air combat capabilities of the Su-27 series fighters, It also has a stronger ground attack capability, with a bomb load of eight or nine tons, which can catch up with the H-6!

  So, the Air Force is looking forward to this aircraft.

"Although that kind of modification is good, it's also expensive." Qin Tao said: "You can buy more than three Flying Leopards for one of that kind of aircraft. If you have any ideas, you should go and have a look. Mr. Lin, you are not embarrassed, are you?"

"If you're embarrassed, just take a look. However, although our air force is poor, we have to spend our money wisely. If the performance of the flying leopard can't meet our needs, then we won't purchase it." Elder Lin said .

After arranging the work of Factory 430, Mr. Lin and Qin Tao and his team came to Factory 172 again, where the Flying Leopard fighter-bombers ordered by the Navy are being produced. Looking at the wing blades on the wings, Mr. Lin couldn't stop shaking his head: " This kind of aircraft is a second-generation aircraft, which is already outdated!"

  Even if the J-7’s wings don’t have the outdated device for controlling airflow separation like wing knives, it still exists on the Flying Leopard fighter-bomber, which is really too backward!

  Old Lin really doesn't like it.

   "Mr. Lin, the Air Force definitely doesn't like this early version, but not necessarily the later version." Qin Tao said.

   "Is there a later version?" Elder Lin asked curiously.

   "Yes, Mr. Lin, we are developing a modified version of JH7. We call it JH7A. The prototype of this aircraft is currently being assembled. Do you want to go and have a look?" Mr. Chen said excitedly.

  After Qin Tao proposed the direction of improvement last time, the 603 Institute started. Although there is still a long way to go to the tall invisible leopard, they believe that this improvement is more suitable now!

  The biggest change is the wing, the wing knife is gone, and the **** are added to the leading edge of the wing. These changes can greatly improve the flying leopard's ultra-low-altitude flight capability. It can be said that it is prepared for the Air Force!

   "Even if the wings have undergone major changes, it does not meet the needs of our air force." Elder Lin said: "What our air force needs is..."

Qin Tao gave him a blank look: "What the air force needs is a two-seater fighter-bomber? What age is this? Why do you still hold on to that kind of thinking? Modern avionics technology is developing rapidly, and the previous It’s visually bombing, and you guys are too conservative, besides, you want to improve on the basis of J-11, it’s also a tandem two-seater.”

   These words made Mr. Lin a little embarrassed. Qin Tao had already spoken out what was in his heart, and he was indeed still clinging to the old ideas.

When the JH-7 project was first established, the Air Force strongly demanded the use of a side-by-side two-seater like the Su-24, which is convenient for the weapon operator to use weapons. Range and other performance, so, after careful consideration, the 603 Institute decided to launch the tandem two-seater project first, which annoyed the Air Force. If you don’t follow my request, then bye!

  The Air Force gave up the JH-7, and the Navy needed a long-range anti-ship missile carrier. They tightened their belts and invested money to get the Flying Leopard out.

   Now, the Air Force is still high above them. It is not so easy to let them turn back.

   After embarrassment, Mr. Lin thought of something: "Then tell me, how far has modern avionics technology progressed, and what kind of combat capabilities can your aircraft possess?"

"Old Lin, when our bomber was just finalized, we used the 234H radar, which is a single-pulse radar that only has maritime search and attack capabilities. Now, we have chosen the JL10A pulse Doppler radar. Not only has more powerful sea search capabilities, but also has complete ground functions, such as terrain tracking, real beam mapping, Doppler beam sharpening and synthetic aperture mapping, etc., relying on these capabilities, our Pilots can better complete the task of ultra-low-altitude penetration. At the same time, we have also integrated radar and flight control. If obstacles are encountered, the flight control system can also operate the aircraft to automatically pull up."

  Mr. Lin's eyes lit up immediately, this performance sounds very good!

Qin Tao knows that the main domestic airborne radar research and development units are the 14th and 607th Institutes, and the 14th Institute also provided the Feibao with a radar code-named 1471. However, due to the busy work of the 14th Institute, it was impossible for this radar to reach The degree of optimization, and 607, as the most professional airborne radar research and development institute in China, is doing all it can to develop this advanced radar, and finally surpassed 14.

  The two institutes are constantly competing, so that they can continue to develop and progress.

   "In addition, our relevant units have also developed low-altitude navigation and attack pods for it, so that it will be more convenient when performing ultra-low-altitude and night attack missions."

  Mr. Lin was very excited: "Well, if it can achieve what you said, it seems not bad."

"We have also added two additional hardpoints, which can carry more weapons, especially our domestic precision ground attack weapons are constantly developing, we believe that the Flying Leopard fighter-bomber will also become the backbone of the air force! "
