Chapter 599 A 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 [-] bombers in total.”

"Air force or 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, and they have been working on it for a long time, trying to get rid of the research and development 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 the batch of second-hand Tu-22M, there is There are about ten H-[-]Js 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 [-] is completed, the project of Turbofan [-] will be launched."

When the slide projector played out the structure diagram, Sobolev felt the depths of his mind. Suddenly, there was a thunderclap. He understood, he understood everything.

After Qin Tao proposed the direction of improvement last time, Institute 603 started to do it. Although there is still a long way to go to become a stealth leopard, they believe that this kind of improvement is more suitable now!
The biggest change is the wing, the wing knife is gone, and flaps 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!

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

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 [-] megawatts at the beginning. Ten megawatts, or even more!

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

"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 the embarrassment, Mr. Lin thought of something: "Then tell me, how far has modern avionics technology progressed, and what kind of combat capability does your aircraft have?"

After accepting the development task, they already had this kind of idea, but whether the project can be established or not depends on whether President Qin supports it.

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 medicine for regret in this world.

According to Qin Tao's suggestion, 601 worked hard to master the production process of the J-27, and improved the J-[-]. After that, it should be able to develop a two-seater fighter-bomber, retaining the air combat capabilities of the Su-[-] 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-[-]!

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.

If we develop the H-20 in the future, then there will be qualified engines to use!

Air Force ordering Flying Leopards?Mr. Lin shook his head: "Our Air Force is waiting for the two-seater J-[-] modified fighter."

"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.

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

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

"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?"

For 055, it is not suitable to change from four to two. Although it can directly drive two propellers, what about at low speeds?

Hearing what Qin Tao said, Elder Jiang's expression turned slightly ugly. Doesn't Mr. Qin support it?

The 052C was equipped with two gas turbines, and the later 055 was equipped with four. Then, wouldn’t it be better to replace one with two more advanced gas turbines?

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 run one engine alone. ah!

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

Even if the J-[-]'s wings don't have such a backward device for controlling airflow separation like wing knives, it still exists on the Flying Leopard fighter-bomber, which is really too backward!
Elder Lin really didn't like it.

Mr. Jiang nodded: "Okay, I get it. 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!"

"How do I feel that the Navy is taking 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."

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

"Thank you for the compliment."

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 modified version of Hong Liu?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 members." Qin Tao thought of something and continued.

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.

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.

"Old Lin, you don't like Liangshan?" Qin Tao said with a smile, "Many people regard them as heroes!"

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

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.

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

That night, many people were 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 say it.

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

"Not now, but there will be in the future." Qin Tao said: "We need [-]-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."

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

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

"Lao Jiang, our navy doesn't have an amphibious assault ship yet." Elder Lin reminded him from the side.

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

"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..."

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!"

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 26 tons. Only [-] knots!Domestically produced aircraft carriers can't be so tasteless.

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.

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.

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

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

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

The answer is really not appropriate.

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.

"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?"

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

"Even if the wings are greatly modified, it does not meet the needs of our air force." Elder Lin said: "What our air force needs is..."

After removing the afterburner, there is still a thrust of more than 100 kN, which is stronger than the power of the D-30K. It is used on a transport aircraft, and the afterburner thrust is more than 200 kN, which can propel the bomber to fly at supersonic speed.

"Old Lin, when our bomber was just finalized, we used the 234H radar, which is a single-pulse radar that only has the capability of searching and attacking at sea. 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."

There was a burst of applause below.

Seeing that Qin Tao didn't speak, Mr. Jiang continued: "Now, the British are developing the MT30 gas turbine engine. This engine is improved from the core engine of the three-shaft Trent 800 aviation turbofan engine. It is said that the maximum output power can reach four. Ten megawatts, that is, more than 5 horsepower. One is equivalent to more than twice the size of our current GT-15000 marine gas turbine."

"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."

"Then who do you think I am like?"

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.

"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."

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

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

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

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

"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.

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.

Immediately, Mr. Lin's eyes lit up, 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 to make this radar reach The degree of optimization, and as the most professional airborne radar research and development institute in China, the 607th Institute did its best to develop this advanced radar, and finally surpassed the 14th institute.

"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?"

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

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

family?

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

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

When the JH-24 project was first established, the Air Force strongly demanded the use of a side-by-side two-seater like the Su-603, which is convenient for the weapon operator to use weapons. Range and other performance, so, after careful consideration, the [-] 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 next day.

"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 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."

Jiang Lao stopped immediately.

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

Now, the Air Force is still aloof, and it's not that easy to turn them back.

052C uses two diesel engines at low speeds, and switches to two gas turbines at high speeds to form diesel-fuel 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?

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 [-]% 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!"

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

"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.

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

Thinking of this, Qin Tao also felt a little emotional, another shortcoming has been made up for!
Although the H-20 of 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.

Qin Tao rolled his eyes at him: "What the air force needs is a two-seater fighter-bomber? What age is this? Why is your air force still clinging to that idea? With the rapid development of modern avionics technology, it is no longer necessary It’s visually bombing, and you guys are too conservative, besides, you want to improve on the basis of J-[-], it’s also a tandem two-seater.”

The two research 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! "
