"Our new bomber project has been approved by our superiors." That night, Mr. Lin, who came from the capital, met Qin Tao and immediately chatted with him: "The superiors have decided to fully launch the surveying and mapping of the Tu-22M bomber.
Due to the imitation work, it is expected that the total number of such bombers will be more than 100."
"Air Force or General?" Qin Tao asked.
"The Air Force and the Navy have not yet been able to spare funds for research and development." Mr. 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 from the Navy came and worked on it for a long time because they wanted to use the Air Force's research and development funds. However, the Air Force has a lot of money and it's time to spend some money.
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 too, but the Navy has no money. After repairing the second-hand Tu-22M, there will be
I'll make do with the H-6J, which is worth about 10 units, for the time being. I'll wait until I have more money later.
"For us, there is not much difficulty in the production of the airframe. The most critical thing is the engine." Mr. Lin said: "This project is of great importance. If the engine can be copied, future models without afterburners may still be used.
It may also be used on our transport aircraft and other aircraft, and the next-generation stealth bomber we are going to develop."
Qin Tao nodded.
In fact, he is not very optimistic about the Tu-22M. He thinks that just dragging out a few to scare people is enough. The most important thing is to develop stealth bombers. But since the navy and air force have such urgent needs, he will not pour cold water on it.
"We have the information obtained from the Kuznetsov Design Bureau and a group of engineers. With these as the backbone, we can still organize a R&D team. We use Factory 430 as the designated R&D factory. We hope that Factory 430 will not be abandoned.
Chain, after completing the full localization of turbofan nine, will launch the turbofan sixteen project."
"Of course, we will do our best." Mr. Jiang nodded: "It's just that Mr. Qin pushed an old man to be the chief commander, I'm afraid some people will be unconvinced."
"Not convinced? We have a large number of old men as chief engineers in various branches of Mingzhou Group, including our fighter project, and they are also the leaders. If anyone disagrees, let them go. If they don't agree,
Then let’s find another factory to engage in research and development. If we don’t have the skills, we will suffer from red eyes.”
Mr. Jiang stopped immediately.
Mr. Lin nodded: "Yes, Factory 430 has been complaining about the lack of projects before. Now that the project is here, if you still want to be picky, you deserve to be without food! Huh, Sibei has been imitating for so many years and has not completed 100%.
The localization task, now there is a new task, are you still not convinced? Mingzhou Group is already starting to lay out an aircraft factory, and at the very worst, it will build an engine factory! Lao Jiang, please pass on what I said and ask them to be honest.
, carry out research obediently, if anyone dares to make small moves and delay this project, be careful I spank him!"
Mr. Jiang nodded: "Okay, I understand. This project is related to the development of our 430 factory. No matter who it is, they must obey the arrangements unconditionally. If anyone tries to do something, I will not let them go!"
That night, many people were destined to have no sleep, and Sobolev did not fall asleep either. He thought about it carefully and felt that something was wrong, but he could not tell it.
After the meeting, Mr. Lin specified that he wanted to stay in the same room as Qin Tao, and they were lying on the bed while they were chatting.
"Taozi, your arrangement is just like the Water Margin. Liangshan will frame whoever he likes, making it impossible for him to live a comfortable life, and he can only become a bandit."
"Mr. Lin, you don't look down on Liangshan either?" Qin Tao said with a smile: "Many people regard them as heroes!"
"Heroes? There may be a few among them, such as the leopard-headed Lin Chong, but most of them are bad guys who kill innocent people indiscriminately."
"Then who among them do you think I look like?"
"You? Song Jiang, you appear to be kindhearted, but in fact you are the most insidious and cunning."
"Thank you for the compliment."
the next day.
"First of all, let us welcome Mao's guests with warm applause. From now on, we are comrades and we will fight side by side!" Qin Tao personally presided over the meeting. Considering that Lao Maozi could not understand Chinese yet, so,
Qin Tao spoke directly in Russian, and 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 engine weight is 3400 kilograms, 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 large engine
Only with the arrival of technical personnel can our project make rapid progress."
When he heard Qin Tao's words, Sobolev's uneasiness became even stronger.
"Now, let's take a look at the structure diagram."
When the slide projector printed out the structural diagram, Sobolev felt a click of thunder in the depths of his mind, he understood, he understood everything.
I don’t know what means Mr. Qin used to get back the information about the Nk-32 engine! And it is conceivable that the outside world will think that it was our own designers who got it back. In the future, if they dare to return to Damao
, they will definitely be arrested as leakers! Therefore, apart from conducting research here in peace and contentment, they will never be able to do anything else.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! You have a home and you can’t go back!
Thinking of this, Sobolev's heart dropped to a low point. Why did he follow Mr. Qin to the East when he was confused? However, there is no regret medicine in this world.
This engine is indeed very important to Dongfang. Dongfang develops various aircraft, but the most lacking thing is the engine. The Nk-32 is known as the most advanced engine for large aircraft in the world, and it also has very good engines.
Without the afterburner, it still has a thrust of more than 100 kilonewtons, which is more powerful than the D-30K. It is great to use on transport aircraft. The afterburner thrust is more than 200 kilonewtons, which can propel bombers to supersonic speeds.
flight.
If we develop the H-20 again in the future, we will have qualified engines to use!
Thinking of this, Qin Tao also felt a little emotional, another shortcoming had been made up for!
Although the H-20 in later generations was developed based on the turbofan ten-core engine, now that there is such a specialized project, it can be used directly.
"Mr. Qin, what kind of aircraft is this turbofan 16 used to assemble?" Sobolev couldn't help but speak.
"Our H-6 modified aircraft is your domestic Tu-16." Qin Tao said: "If we want to upgrade our bombers, we must have more advanced power."
Modification of H-6? Sobolev still doesn't believe it. Does the modification of H-6 need this kind of engine? However, since Mr. Qin said it, there shouldn't be any problem, right?
He trusted Qin Tao until a few years later when he saw the plane and his eyes dropped in surprise. You guys call this kind of plane a modification of the H-6? This is obviously a modification of the Tu-22M.
!
"By the way, please feel free to work here. We are trying to find a way to bring your family here." Qin Tao thought of something and continued.
family?
A warm current surged in Sobolev's heart. If his family came over, there would be nothing to say. From now on, he could work here with peace of mind.
"I don't know how the materials and processes are progressing here. I think if there are no accidents, we should be able to complete the research and development of this engine within five years." Since Sobolev has become the chief designer, he has to
He issued a military order. He was very familiar with this engine. There was no problem with the design. The main thing was how to process it. In the past five years, he had to study the processing technology.
"Okay, then I'm looking forward to your results. Five years later, when this engine is developed, your superiors will hold the most grand commendation meeting for you and give you a large bonus!"
After making some promises, the meeting was over. Factory 430 allocated a group of technical personnel 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 research and development of this engine is completed, it will become the most advanced aerospace engine in our country. If we use the technology of this engine to develop a gas turbine, I wonder if the navy has this demand?"
Using aircraft engines to derive gas turbines is the most common practice in the West. Gas turbines modified by Spey once supported the fleets of many countries. The LM2500 of the United States was also modified from aircraft engines.
Factory 430 has been working hard to develop in this direction. There was an idea to modify the gas turbine on the Spey engine before, but because the Navy already had Ermao technology, it was finally abandoned. When the Navy was working on gas turbines, Factory 430 also participated.
, and even fantasized about taking the lead, but in the end had to give up.
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. This engine is improved from the three-shaft Trent 800 aviation turbofan engine core machine. It is said that the maximum output power can reach four
Ten megawatts, that is, more than 50,000 horsepower. One unit is equivalent to more than twice the power of our current GT-ship gas turbine."
The interior of an aero engine is extremely complex. In order to better adapt to different air flow rates, modern aero engines are at least dual-rotor. The high-pressure area and low-pressure area have different speeds. Except for the French M53, which has a single rotor, there are almost no
The second one.
However, dual rotors cannot fully adapt to the complex internal aerodynamics, so a three-rotor engine has emerged. The three shafts are divided into three different speeds: high, medium and low. The adaptability is stronger, but at the same time, the internal complexity will also 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 its output power is very high. If this kind of aero engine is used to derive a gas turbine, it will not be difficult to have an output power of forty megawatts initially. After improvement in the future, it may be able to output five
Ten megawatts or more!
They already had this idea after accepting this development task, but whether they can establish the project depends on Mr. Qin's support.
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 when used on a destroyer, and somewhat insufficient when used on an aircraft carrier."
Hearing what Qin Tao said, Mr. Jiang's face turned a little ugly. Doesn't Mr. Qin support it?
The current Gt- will be further upgraded to GT-. The output power will be increased to 20 megawatts or even higher.
The 052C was equipped with two gas turbines, and the later 055 was equipped with four. So, wouldn't it be better to replace one with two more advanced gas turbines?
The answer is that it's really inappropriate.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! 052C uses two diesel engines at low speed, and switches to two gas turbines at high speed to form diesel-gas alternating power. If a more powerful one is used
Gas turbine, then there is a question, which propeller does this gas turbine drive? Or is it divided into two propellers through gear transmission?
When used on the 055, it is not suitable to convert four propellers into two propellers. Although it can directly drive two propellers, what about low speed?
Gas turbines consume quite a lot of fuel. At low speeds, the 055 only needs to turn on two engines, or even just one, to carry out economic cruising. If four engines are turned into two, then operating one engine alone will still consume a lot of fuel.
ah!
It can be used on aircraft carriers, but aircraft carriers face insufficient power. Just look at the British Queen-class aircraft carriers. They forced gas turbines, but only two were installed because they were afraid of spending money. As a result, the maximum speed of the 60,000-ton aircraft carrier was
Only 26 knots! Domestic aircraft carriers cannot be so useless.
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 would be very suitable."
The appearance of amphibious assault ships looks similar to aircraft carriers, but their combat missions are different. They are not used to seize air superiority, but to attack the ground. Therefore, the straight flight deck is used to take off and land helicopters or vertical
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 align with 40,000 tons, but at the same time it does not need to have the high speed of an aircraft carrier.
Therefore, if the development of high-power gas turbines from the 430 Factory matures, two of them can drive a 40,000-ton amphibious assault ship!
Mr. Jiang's eyes lit up: "Mr. Qin, do you support our project?"
"Lao Jiang, our navy doesn't have amphibious assault ships yet." Lao Lin reminded from the side.
"We don't have it now, but we will have it in the future." Qin Tao said: "We need a 40-megawatt gas turbine. When we sell it to foreign customers, we also need this kind of gas turbine. After the research and development of Turbofan 16 is completed, we will
My personal opinion is to support the development of naval gas turbines based on this aero-engine."
"Thank you, Mr. Qin!" Mr. Jiang was excited.
"Why do I feel that the Navy is squandering our Air Force's R&D funds again?" Mr. Lin was a little dissatisfied: "Now the funds for the entire project go to our Air Force's account, and the Navy just eats what is ready."
"Mr. Lin, your air force can also eat ready-made food." Qin Tao said: "Since we are here, let's go see the flying leopards. Maybe your air force can order a batch?"
Is the Air Force ordering the Flying Leopard? Mr. Lin shook his head: "Our Air Force is waiting for the two-seat J-11 modified fighter."
According to Qin Tao's suggestion, the 601 Research Institute has worked hard to master the production technology of the J-11 and improved the J-15. It should be able to develop a two-seat fighter-bomber while retaining the air combat capabilities of the Su-27 series fighters.
It also has stronger ground attack capabilities, and can easily carry eight or nine tons of ammunition, which is comparable to the H-6!
Therefore, the Air Force is looking forward to this kind of aircraft.
"Although that kind of modification is good, it is also expensive." Qin Tao said: "You can buy more than three Flying Leopards for one aircraft of that kind. If the Air Force is extremely rich, of course you don't need to look at it. If the Air Force has this
If you have any ideas, you should go and have a look. Mr. Lin, are you embarrassed?"
"If you're sorry, just take a look. However, although our Air Force is poor, money must be spent wisely. If the performance of Feibao cannot meet our needs, then we will not purchase it," Mr. Lin said.
.
After arranging the work of Factory 430, Mr. Lin, Qin Tao and his team came to Factory 172, where the Flying Leopard fighter-bombers ordered by the Navy were being produced. Looking at the wing blades on the wings, Mr. Lin couldn't help but shake his head: "
This kind of aircraft is a second-generation aircraft and has long been outdated!"
Even the wings of the J-7 don’t have wing knives, a backward device that controls airflow separation. However, there is still one on the Flying Leopard fighter-bomber. It’s really too backward!
Mr. Lin really doesn't like it.
"Mr. Lin, the Air Force will definitely look down on this early version, but that's not necessarily the case for later versions." Qin Tao said.
"Is there any later version?" Mr. Lin asked curiously.
"Yes, Mr. Lin, we are developing a modified version of the JH7. We call it JH7A. The prototype of this aircraft is currently being assembled. Do you want to take a look?" Mr. Chen said excitedly.
After Qin Tao proposed the direction of improvement last time, Institute 603 took action. Although there is still a long way to go to reach the tall invisible leopard, they believe that this kind of improvement is more suitable now!
The biggest change is the wing. The wing blades are gone and flaps are added to the leading edge of the wing. These changes can greatly improve the Flying Leopard's ultra-low-altitude flying capabilities. It can be said that it is prepared for the Air Force!
"Even if the wings are greatly modified, it will not meet the needs of our air force." Mr. Lin said: "What our air force needs is..."
Qin Tao rolled his eyes at him: "What the Air Force needs is a two-seater fighter-bomber? How old is this? Why does your Air Force still hold on to that kind of thinking? With the rapid development of modern avionics technology, it has long been no longer needed.
visual bombing, you are too conservative. Besides, you want to improve on the J-11, which is also a tandem two-seater."
These words made Mr. Lin a little embarrassed. Qin Tao had already spoken out everything in his heart. He indeed still held on to his past concepts.
When the JH-7 project was first established, the Air Force strongly requested the use of a side-by-side two-seater like the Su-24, which would make it easier for weapons operators to use weapons. However, this side-by-side two-seater solution would greatly increase the fighter's windward area, reduce speed and
Range and other performance, so after careful consideration, the 603 Research Institute decided to launch the tandem two-seater project first. This annoyed the Air Force and if it did not comply with my request, then bye bye!
The Air Force gave up on the J-7, and the Navy needed a long-range anti-ship missile carrier aircraft, so it tightened its belt and invested money to create the Flying Leopard.
Now, the Air Force is still superior, and it is not that easy to let them turn back.
After the 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 have?"
"Mr. Lin, when our bombers were first finalized, we used the 234H radar, which is a monopulse radar that only has maritime search and attack capabilities. Now, we have chosen the JL10A pulse Doppler radar. This radar
It not only has more powerful sea search capabilities, but also has complete ground functions, such as terrain tracking, real beam mapping, Doppler beam sharpening, synthetic aperture mapping, etc. With these capabilities, our
Pilots can better complete the mission of ultra-low-altitude penetration. At the same time, we have integrated radar and flight control. If an obstacle is encountered, the flight control system can also operate the aircraft to automatically pull up."
Mr. Lin's eyes suddenly lit up. This performance sounds very good!
Qin Tao knew that the main domestic airborne radar development units were the 14th Institute and the 607th Institute. The 14th Institute also provided Feibao with a radar code-named 1471. However, the 14th Institute was too busy with its work and could not make this radar reach the desired level.
The level of optimization, and the 607th Institute, as the most professional airborne radar research institute in the country, tried its best to develop this advanced radar, and finally surpassed the 14th institute.
The two institutes continue to compete 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, which will make it easier to carry out ultra-low-altitude and night attack missions."
Mr. Lin was very excited: "Well, if it can achieve what you said, it seems to be pretty good."
"We have also added two additional hardpoints to carry more weapons, especially as our domestic precision ground attack weapons continue to develop. We believe that the Flying Leopard fighter-bomber will also become the backbone of the Air Force!
