Chapter 613 Technology has surpassed Lao Maozi

"If it was a cooperative development of fighter jets, of course they could use our appearance design, but now, instead of cooperative research and development, they used our two-seat trainer aircraft to convert it into a fighter-bomber without our authorization. This way It’s not allowed!”

Forget what happened with the J-15 last time, and now they are playing the same trick again. Do you really think our Sukhoi Design Bureau will tolerate this kind of behavior? If you can produce everything, then our Komsomolsk Aircraft Factory must not close down?

Emelyanov must stick to his principles, even if Qin Tao is with him. It is impossible for him to give up his intellectual property rights just by saying a few words here!

You must be tough this time.

"So, what are you going to do? Compensation?" Qin Tao patted Yemelyanov on the shoulder: "It's meaningless to have such a stalemate. If you believe me, I can help you get rid of it. Let’s coordinate.”

"Coordination? How can you coordinate?" Yemelyanov looked at Qin Tao.

“Well, how about we talk while walking? Don’t delay their work, the plane can’t run anyway.”

Emelyanov looked at the plane, then at Qin Tao, and finally chose to listen to Qin Tao.

 After all, Qin Tao and them are good friends. They have worked together on many things before. This time they encountered something that made them angry. Maybe Qin Tao can help solve it.

"All right."

"My old friend, many things have to be considered from a different perspective, and they will suddenly become clearer." Qin Tao and Yemelyanov walked on the runway and began to give him guidance: "For example, here now The research and development of a two-seat fighter-bomber has been completed. Even if you protest and cause an international commotion, it will be meaningless."

 “Change the angle? How?” Yemelyanov asked.

“Last time during the J-15 telex troubleshooting, you proposed to sell a Su-35. What kind of aircraft is this?”

Hearing Qin Tao's question, Yemelyanov immediately became interested: "Mr. Qin, this is the latest modern fighter developed by our Sukhoi! The Su-37 that often appears at air shows, It is a model that is based on the Su-35 and is equipped with a vector nozzle. If you can purchase a batch of Su-35, we will no longer pursue you for imitating the Su-30."

"Well, I can help you coordinate. I wonder if you can send a Su-35 over to give us a live demonstration? In this way, the leaders of our Air Force can see the advanced performance of this fighter, and maybe I can now make a purchase decision.”

Yemelyanov just wanted to nod, but then thought of what happened to the Su-30, and immediately shook his head: "No, no, we can't fly the most advanced fighter jets over. You can organize an inspection team to go to our Su-30." Hoy to see the wonderful performance of this fighter aircraft!"

“Okay, let’s work separately. I’ll help convince the leadership of the Air Force. You contact the Sukhoi Design Bureau for us to investigate the Su-35.”

Yemelyanov nodded, but when he looked at the aircraft again, he thought of something and continued: "If you don't purchase the Su-35, then we will still pursue the patent of that aircraft. infringement.”

"My friend, you'd better save yourself." Qin Tao patted Yemelyanov on the shoulder again: "Don't harm the Rulika-Saturn coalition."

  Leurica-Saturn? What does it have to do with them? Yemelyanov was puzzled.

“I came here to observe the flight of this aircraft. After the visit, they invited me to the 606 Design Institute.”

 606 Design Institute? Hearing Qin Tao's words, Yemelyanov pondered for a few seconds before reacting: "Did your self-developed engine succeed?"

 At present, there are not many imported materials for the J-11 and J-15 on the production line, including engines and ejection seats, etc., which need to be imported. Many other parts can already be produced here.

 The only thing they can get stuck in is the engine. Now, is there going to be a breakthrough in this aspect?

Although Dongfang has a replica version of the R-79 engine, after all, this engine has too much weight and excess thrust, so it is not the best choice for the J-11. However, if a similar engine is successfully developed, then the engine will also be exported in the future. Reduced to zero!

 Emelyanov’s face has changed.

"If we continue to have a good relationship, I can still convince the superiors that even if the self-research is mature, we can continue to purchase your engines. If there is a stalemate, you will still suffer the loss."

Qin Tao took advantage of this opportunity and hit Yemelyanov again, so that this guy would not always feel that he was still standing on the commanding heights.

 “Can I go and see it together?” Yemelyanov asked.

"Well, I don't know much about this yet, but if you think that this engine is a copy of the third uncle's, you are totally wrong." Qin Tao knew what the other party was thinking: "This third-generation highly recommended project is It was in the 1980s, much earlier than the introduction of the Su-27. If I have to say imitation, it is also an imitation of the American F110 engine, and it is definitely not your third uncle."

 “Copy American engines?”

"Yes, in the 1980s, our relationship with the West was still very good. It was normal for us to obtain advanced engines from the West and then conduct mapping and imitation. So far, the West has not accused us of copying their engines. Mr. Yemelyanov, if you insist on pursuing infringement, you will really lose more than you gain. In the field of military industry, there is no infringement, only whether it can be produced."

 Qin Tao finally made his words clear.

　On the one hand, if you don’t pursue the matter, we will give you benefits and everything can be easily discussed. On the other hand, if there is a stalemate, we have nothing to fear.

“Qin, I still want to take a look. As a Sukhoi expert, I want to know whether that kind of engine can be used on the Su-27.”

"Okay, let me apply for you. We are very polite to our friends. You should be qualified for this inspection." Qin Tao said: "However, that kind of engine is not used on the Su-27. The original plan It is used on the Jian Shi."

The J-10 has been finalized and is using the Third Uncle. These people in the Sukhoi Design Bureau know that now, Qin Tao has made them feel a sense of crisis and told them that these are all forced by you, otherwise we will still be good friends. ah.

The J-16 has been preparing on the tarmac for more than two hours, and more and more people are watching around it.

When he saw Mr. Lin's figure, Yemelyanov immediately became nervous.

Of course he knows that Mr. Lin is a big boss in the Air Force with a high position of authority. It was this man who single-handedly facilitated the purchase of Su-27 fighter jets by Dongfang. Now, this man has come to participate in the first flight of the J-16, which fully illustrates this. The importance of fighter jets.

Now, what should he do?

Go up and denounce the shamelessness of the Easterners and copy their fighter planes? Or ask for more orders from Easterners?

Just when he was hesitant, he saw Qin Tao walking up and saying something in Mr. Lin's ear. Then, Mr. Lin looked towards him.

Yemelyanov suddenly became excited. Qin was indeed his good friend. At this time, he could mediate for his side and find the best solution! Just like the design of the fourth-generation aircraft, it was Qin who promoted it. The Sukhoi Design Bureau also benefited a lot from this design. Now, Qin is helping to solve the problem again!

 In his expectant eyes, Mr. Lin walked over.

“Mr. Yemelyanov, do you have an air superiority fighter that is more advanced than the Su-27?”

Hearing this question, Yemelyanov nodded quickly: "Yes, our fighter is the most advanced heavy air superiority fighter in the world! It is also your best choice!"

"Okay, then please contact the Sukhoi Design Bureau as soon as possible and arrange a flight show for us so that we can watch this most advanced fighter aircraft up close. If it can meet our needs, we will purchase forty in the first batch. shelf!"

 “Okay, okay!” Yemelyanov was overjoyed.

“Mr. Lin, today we have also arranged the task of inspecting the 606th Institute. Do you want to take our good friend Da Mao with us?”

 “Okay, let’s go together.” Mr. Lin nodded.

The roar of the engine came, and the J-16 started the engine. Under everyone's attention, the plane taxied from the runway and took off. The whole action was extremely smooth. In the cockpit, the two pilots were low in front and high in back. The upper body can also be seen very clearly.

“Mr. Yemelyanov, how is our J-16 fighter?” Mr. Lin asked Yemelyanov excitedly.

What else? Yemelyanov cursed in his heart, but he could only say: "Mr. Lin, this plane is very good."

"The successful development of this aircraft represents a new level in our ability to develop self-developed fighter aircraft." Mr. Lin said: "We have already self-developed the J-15, and now we have the J-16. From now on, we will There will be more and more advanced fighter jets."

 What about self-research? You are clearly copying our fighter planes! Yemelyanov was extremely unhappy, but he couldn't say anything and could only force out a smile.

 Fortunately, the plane did not fly away directly. Twenty minutes later, the plane landed on the runway again.

 “Can I go up and have a look?” Looking at the green thing in front of the cockpit, Yemelyanov couldn't help it.

“Welcome, you can go up and have a look. It’s completely different from your Damao Watch Shop.” Qin Tao said, and then thought of something after he finished speaking: “Is the cockpit of your Su-35 still a watch shop?”

“Of course not. Over the years, our avionics system has also developed. The latest avionics system also has a display layout, and we have four displays in the cockpit.”

The greater the number of monitors, the worse the integration performance of the system. If the other party brags about four monitors, it is a big mistake. Just look at future generations and you will know that the most advanced fighter jets only have one integrated monitor. There is much more content.

"There is no operating lever in the back seat, so this is a fighter-bomber." After stepping up the gangway and seeing the cockpit layout, Yemelyanov couldn't help but muttered. When he just saw the aircraft, the technician He even tried to fool him into thinking he was a trainer!

The layout of the front and rear cockpits of the trainer aircraft are the same, and the position of the instructor in the back seat must also have an operating lever, so that the instructor can take over the operation of the aircraft at critical times.

If we want to talk about a special case, that is the Tomcat fighter jet. It is originally a two-seater, and there is no way to open up a third seat for the instructor. Therefore, the method adopted by the Americans is to let the instructor sit in the back of the radar officer's position and speak orally. It is a way to teach pilots in the front cabin flying skills and give them tips on flying skills. It is a miracle that there are no accidents in this way.

 The first flight ceremony was over, and after lunch, everyone headed to Institute 606.

 The old industrial base in the Northeast is almost the largest industrial center after the founding of the People's Republic of China, and the aviation industry also started here. There is the 601 Institute that develops aircraft, the 112 Factory that produces fighter planes, the 606 Institute that develops engines, and the 410 Liming Factory that produces engines.

 Speaking of the research and development of engines, we have to mention the father of domestic aviation engines, Mr. Wu.

Mr. Wu lived in the war years and went to the United States to study. After returning, he joined the aviation industry.

In the 1950s, with the introduction of the MiG-17 into the country, the matching VK-1F engine was also introduced. At that time, Mr. Wu was the designer of the engine. After the J-5 was successfully copied, there were many differences in how the aviation industry developed. Some people thought that imitation or import would be enough, but what Wu Daguan, who was the director of the Second Production Division at the time, thought was that only by independently developing engines could China truly achieve a qualitative leap.

 Mr. Wu and Mr. Xu jointly submitted a report, suggesting that they should design and manufacture their own engines, and at the same time establish aerodynamic research and aero-engine research institutions!

 After approval from superiors, Mr. Wu first established the first domestic jet engine design room in the 410 Factory and served as the director of the design room. When all conditions were not met, the design of my country's first jet trainer power engine began.

In 1961, Mr. Wu and the leaders of the Air Force at the time established Institute 606. Mr. Wu served as the deputy director and aero-engine expert, and jointly took charge of China's first aero-engine research institute.

Going through the twists and turns of many models, Mr. Wu later went to the 430 factory to help imitate Sibei, and never came back. However, he was still concerned about Institute 606, and Mr. Wu was the driving force behind the ten turbofan projects.

Now, the chief designer of Turbofan 10 is Mr. Zhang. As the person in charge of this project, he feels a great responsibility and a lot of pressure. Looking at his white hair, Qin Tao also feels very emotional. It is because of unknown scientific researchers like Mr. Zhang who work day after day that the motherland's military industry has finally developed to the world's top level!

The early Turbofan 10 was also extremely immature, so many people said that it was not very good. However, later on, the Turbofan 10 finally matured, and even forced the Turbofan 15 to go back and improve its performance.

"Welcome, welcome everyone to come to our 606 Institute for inspection." Mr. Zhang greeted everyone enthusiastically. When he saw Yemelyanov, he was very enthusiastic: "Mr. Yemelyanov? Are you Sukhoi Design The consultants sent by the bureau will definitely be able to give us better advice on our engines. Please come in, please come in quickly!"

 Everyone first came to the conference room, and the introduction of Turbofan 10 was played on the projector screen.

"Our turbofan ten engine uses a three-stage fan, nine-stage rectification, one-stage high pressure, one stage low pressure, a total of twelve stages, and a single-stage high-efficiency, high-power, high-low-pressure turbine. It is a high-thrust, high-thrust-weight-ratio, low-bypass-ratio Advanced engines.”

A layman sees the excitement, an expert sees the door. Yemelyanov just took a look at the structure of the engine and knew that it was different from his third uncle. In jargon, the structure of the turbofan ten is 3+9+1+1, and The third uncle is 4+9+1+1. If there is one less fan, it is a different type.

“At that time, the turbofan six we developed was abandoned halfway, but we believe that the current turbofan eleven will be successfully developed. Its initial thrust can reach 13 tons. When the later improved model is developed, it can easily reach 14 tons.”

Listening to these data, Yemelyanov's face became more and more ugly, and he had already heard the meaning of these words.

 If this engine is successfully developed, then there will no longer be any need for their third uncle to sell it to the East. The Orientals can have better and more advanced engines!

 If you want to sell, you can only sell more advanced engines!

“As for the life span that the Air Force is most concerned about, the first overhaul life of our engine can reach 1,000 hours, and the full life span can reach 3,000 hours.”

Emelyanov was stunned again.

The characteristic of Lao Maozi is its short lifespan. On the battlefield, it can fly for less than a hundred hours before being destroyed. However, in peacetime, its short lifespan becomes a liability.

The life span of Third Uncle's first overhaul is three hundred hours. After two or three overhauls, it will be scrapped. The entire life span is only about one thousand hours. The lifespan of this advanced engine in front of me is three times that of theirs!

 This means that the cost of using the engine will be greatly reduced!

Yemelyanov's heart was in confusion, and a thought appeared in his mind: How is it possible, the engine is the crown of the aviation industry, do Easterners have this ability? Can we develop an engine whose performance far exceeds our own?

At this time, Mr. Zhang continued to explain. When he saw the picture of the internal core machine, he seemed to understand.

This core engine is very similar to the American engine. This time the Easterners did not copy Da Mao, but copied the Western engine! For some reason, a feeling of loss suddenly arose in his heart.

 In the past, the target of plagiarism by Easterners was Lao Maozi, but what about now? Orientals actually look down upon it!

In the following time, Yemelyanov was in a state of confusion. He only heard a lot of things scattered about, such as the turbine front temperature of 1,800 Kelvin, and the special alloy materials. In short, this engine sounded It looks very classy!

However, is such an advanced thing real? Will these people deliberately use a PPT to deceive themselves? Yemelyanov looked for comfort for himself and finally found such a reason.

But soon, his idea was proved untenable.

“Everyone, we can go to the high-altitude test bench now. Our engine is currently undergoing high-altitude test run.” After the introduction, Mr. Zhang led everyone to the test bench.

High-altitude test run is already the last step before the engine is installed on the aircraft, which shows that the development of this engine is very smooth!

With mixed emotions, Yemelyanov looked at the engine running at high speed on the test bed. The roar of the engine came to his ears, and his face became even more ugly.

"Through the test on the high-altitude test bench, we have obtained the complete thrust envelope of the turbofan ten. What excites us most is its high-altitude and high-speed performance." Mr. Zhang continued to introduce to everyone: "Look, there is a blackboard here. , what is drawn above is the envelope of high-altitude and high-speed performance that we tested.”

 The horizontal axis is M and the vertical axis is KN. Each line is the thrust envelope at a certain altitude. When he saw this picture, Yemelyanov opened his eyes wide.

The thrust loss of this turbofan at high altitude is significantly smaller than that of the third uncle. Moreover, the thrust recovery characteristics at high speed are much stronger than that of the third uncle. It can operate at multiple speeds and at multiple altitudes at high speeds above the speed of sound. , it can produce more than 20KN of thrust at most than the third uncle.

When talking about the maximum thrust of a certain engine, this is actually a limiting condition. Most turbofan engines lose thrust at high altitudes and at high speeds. However, the engine in front of us loses very little thrust. It’s simply the turbojet in a turbofan!

 There is very little thrust loss at high altitude and high speed, which means that this engine has excellent high altitude and high speed performance, which is very important for fighter aircraft to perform emergency missions. Even if it cannot cruise at supersonic speed, it can at least fly at the fastest speed at high altitude.

The performance of this kind of engine is even better than that of my third uncle!

So, will Orientals continue to purchase Sanyifu in large quantities?

Yemelyanov was in a very bad mood after coming out of the 606 Institute. When he went to the bathroom, he happened to see Qin Tao again and immediately asked for help: "Qin, you are completely out of control." Need the rhythm of our engine.”

Although the engine is from the Ryulica-Saturn consortium, the Sukhoi Design Bureau is the general contractor, and they can still make money from it. But now that the Orientals have advanced engines, it is impossible to purchase Sanyi in large quantities. Well, the Sukhoi Design Bureau will have to spend a lot less money.

"How is that possible?" Qin Tao smiled: "If it is my third uncle, maybe we will reduce the purchase quantity in the future, but you have a more advanced engine than my third uncle!"

 An engine more advanced than my uncle’s? Yemelyanov's face was suddenly stunned: "Is Mr. Qin talking about his fourth uncle?"

According to Lao Maozi's model development rules, after the third uncle, there will be the fourth uncle, that is, the AL-41F engine. As the engine of the next generation fighter, its development is even earlier than the MiG 1.44 project.

“You should have this kind of engine, right? I remember that at the Mikoyan Design Bureau, Project 1.42 used this kind of engine.”
