Chapter 786 The development of the H-6J began in the 1970s

"Dear audience friends, I am very happy that we meet again. Today, the theme of our Zhang Zhong Talks program is Zhang Zhong Talks about H-6." Zhang Zhong also appeared on the TV screen as scheduled. Compared with several news programs, In a word, Zhang Zhong said that the program is longer and the introduction is more detailed.

"We know that in this maritime parade, our navy displayed the H-6J bomber. This bomber has a lot of changes. We are also very curious, so we immediately invited Mr. Chen, a famous domestic aircraft expert, to please He came to tell us the story of Hong LiuJ."

Mr. Chen is the chief engineer of the J-H-7. It is of course very authoritative for him to talk about the H-6J.

"It is really not easy for the H-6J to get to where it is today. After all, this project started in the 1970s. At that time, many aircraft designers worked hard for this bomber and spent many years. Now it can It’s really touching to realize that you have achieved positive results. Some old people who had just come into contact with this project didn’t even see its heroic appearance.”

“It started in the 1970s? In other words, this project has been going on for thirty years?”

Mr. Chen nodded: "Yes, but the project has always been kept secret. Until now, the H-6J has been publicly displayed, so we can say something. Those unknown people at the time were all contributors to this aircraft!"

“Mr. Chen, could you please give us a detailed introduction, for example, how was this project established?”

"Back then, we had mastered the H-6 production technology, but this bomber was too backward after all. We had to make large-scale improvements to the H-6 to better adapt to future wars. After all, flying to the enemy's It is not easy to drop bombs overhead. In the 1970s, the most popular aviation technology was variable swept wings. Therefore, we planned to improve the H-6 into a variable swept wing fighter. At that time, it was not just us We are currently working on this project, and other domestic units are also working on this project, such as the 320 Factory, which was working on the Q6 at that time and also used variable sweep wings."

“Mr. Chen, the H-6 uses a wing root engine layout. I’m afraid it’s not easy to change the swept wings in this way, right?”

"Yes, at that time, we studied for a long time and wanted to solve the problem of the rotary shaft of the variable sweep wing arranged at the wing root, but no matter how much we studied, we could only make drastic changes and change the engine nacelle from The wing root area has been moved to the tail of the aircraft. I have several design drawings from that time, you can take a look."

Design drawings appeared on the screen. The first one only changed the variable sweep wing. The engine nacelle at the wing root seemed to have two corners growing out. That was a large wing box with the wings mounted on it. How do you see it? awkward.

 The second picture is still like this, but the wing box is moved upward to form a high-wing structure. The engine is directly under the wing box. This picture looks more pleasing to the eye, but there are still problems.

 The third picture is a complete overhaul, the engine is placed at the rear and the air intake is moved forward.

"If you look at this design drawing, you can see its huge air inlet. This design is based on the MiG-25. However, in order to facilitate the mounting of weapons, a lower-wing layout is made. It is just the shape of the body. We argued over it for more than ten years, and in the 1980s, we finally completed the aircraft's appearance design, and then we discovered another big problem we were facing."

"what is the problem?"

 “Engine.”

"If we want this aircraft to have the performance of a variable swept wing, we need a powerful engine. The turbojet-8 we copied before cannot provide enough thrust at all, so we started to improve its engine again. ."

“Improve the engine? Is it by adding an afterburner behind it?”

"Yes, that's it. Our Turbojet-8 originally only needs to propel the H-6 at subsonic speed, so it only needs an ordinary jet engine. However, if we want it to fly at supersonic speed, we have to use acceleration. Therefore, based on this engine, we added an external afterburner."

 “The engine is our weak point.”

“That’s right, we used the Turbojet-8 for test flights to verify the aerodynamic design of the airframe, and at the same time we started working on the afterburner. It took more than ten years for this project to finally succeed.”

“In other words, our aircraft is modified from the H-6 engine?”

"Yes, it is the afterburner variant of the Turbojet-8. However, we also have our own innovations. For example, we have used modern technology to make a lot of improvements to the Turbojet-8. The life of this engine has increased from eight hundred The hours have increased to 2,000 hours, the military thrust has increased by 20%, and the fuel consumption has also been reduced by about 10%. If our old H-6 had not already used the D-30K, we would really want to use this to improve it. Our old Todoroki."

“So did you encounter any other problems during the development of this aircraft?”

"There are many problems. For example, when this aircraft was developed, it was aimed at future warfare. It can fly at high altitudes and at high speeds, and can also penetrate defenses at low altitudes and high speeds. During the low-altitude and low-speed flight tests, this aircraft was almost An accident occurred once, and it almost caused a crash. Fortunately, we finally persevered. In recent years, our technology has improved, and we have used advanced terrain avoidance technology to make low-altitude and low-speed penetrations more easily."

“Modern warfare has entered the era of stealth aircraft. Mr. Chen, have you ever thought about making stealth improvements to your bomber?”

"Yes, stealth machines are a trend, but we can also see that stealth technology is not omnipotent. In this war, stealth machines were shot down. Therefore, we believe that stealth machines are important, but long-range attacks Ability is more important, so the improvement of our H-6J mainly lies in the weapon system. For example, we have mounted long-range attack weapons on it, allowing it to launch attacks outside the enemy's defense zone."

 Zhang Zhong said that the "Hong Kong Six J" program was broadcast all over the world, and many people had mixed emotions after watching the program.

"This is a joke! Do they think that by fooling Mao like this, they can get rid of the relationship with Mao? This is clearly the Tu-22M bomber. Mao sold this bomber to the East. They went too far!"

 “We must let Da Mao know the consequences of doing this!”

“They not only sold the Tu-22M bomber, they even sold the production line. Someone has to pay for it!”

This time Zhang Zhong said that the intention of the program was very obvious: The H-6J has nothing to do with the Tu-22M. We have been developing it since the 1970s and have been developing it until now. It is finally in service. This is the development of our domestic aviation technology. result!

 Let’s make it public anyway. As for whether others believe it or not, that’s their business and has nothing to do with you.

 Tupolev Design Bureau.

“This is nothing but nonsense. How can our Tupolev Design Bureau sell Tu-22M information to Easterners at will?” Lev-Bazenkov said angrily.

The previous chief designer, Valentin Briznukko, has retired. Currently, the person taking the lead in the Tupolev Design Bureau is Bazhnkov, the former assistant of Bznukko. He is facing the investigation. Government officials were very angry.

A bomber similar to the Tu-22M appeared in the East, and then the government began to doubt it. This is obviously a slander.

"Then how did the Orientals create the Tu-22M bomber? As a designer, you should know that it is impossible to improve the Tu-16 into the Tu-22M. Even if you change the Tu-22, you cannot change it into the Tu-22M. These are clearly two different aircraft," the government official asked.

"How do I know?" Bazenkofu continued: "When the Red Empire collapsed, we were not the only ones who had Tu-22Ms. Other countries also had many bombers of this level scattered around. For those countries, selling such aircraft It is not impossible to change the bread. There may even be people in our own army who do this. For money, they can sell anything, not to mention the Tu-22M, and even the Tu-160. Lose."

“You are saying that the H-6J displayed by Dongfang is actually a refurbished version of our Tu-22M?”

"I don't know about that. Renovation is more likely. After all, it is not easy to build a bomber of this level from scratch. The aviation industry in the East is indeed developing very fast. However, if you want to study a bomber of this level, you still have to It's a little short of heat. If nothing else, it's difficult to produce the engine. It's simply impossible to modify it from the original turbojet-8."

 Government officials breathed a sigh of relief.

With the Tu-22M, the East can not only deal with countries in the East, but these bombers may also fly to the north. They must take precautions in advance. After all, in this era, the threat from bombers is still great.

 As for the American protests? It doesn't matter, do they still care about other people's protests? If someone presses hard and annoys them, the worst they can do is hit them with a fist.

“Your Tupolev Design Bureau has suffered a serious loss of personnel in recent years. Is it possible that they will go to the East and help the Easterners imitate this bomber?”

The Orientals’ surveying and mapping imitation capabilities are so powerful that people have to be wary of them.

“This is beyond our control. If we don’t have other projects, our entire design bureau may collapse. It is not our responsibility to ask where our designers who have left will go.”

 When he said this, Baz Enkov was also a little depressed.

 Things are like this, what can he do?

Who made Da Mao fall?

 East.

“The recent public display of our H-6J has caused a sensation.” Wu Shengli said to Qin Tao: “A lot of pressure is directed at the Tupolev Design Bureau.”

Qin Tao smiled: "Well, the rumors stop with the wise. We have publicly announced that the H-6J is completely improved by ourselves. These people just don't believe it. They don't believe it, and there's nothing I can do about it."

“Well, what will you say when the white swan shows up in the future?”

The H-6J was shown to the public this time, and it has already caused such a big sensation. If the White Swan is shown in the future, it will shock countless people.

The H-6J is just a bomber with a maximum takeoff weight of more than 100 tons and can fly several thousand kilometers. The White Swan is a strategic bomber and can fly more than 10,000 kilometers.

“What’s this? It’s just a four-engine modified version of our H-6J.” Qin Tao said.

The White Swan is a strategic weapon and cannot be displayed casually. It is more secretive. However, if it is displayed, our side will be generous. Wouldn't it just give the H-6J two more engines? What's so surprising?

“If we hadn’t entered the era of stealth machines, it would have been a good plan for us to map and imitate the White Swan.” Wu Shengli continued.

“Yes, if it had been twenty years earlier, we would have definitely mapped and imitated the White Swan. Forget it now, our stealth bomber is the most important project, and the country cannot support too many projects.”

"After our public display this time, the whole country became a sensation, which strengthened our national and military prestige. Taking advantage of this east wind, our national defense lottery tickets sold more." Wu Shengli continued: "The navy's military expenditure is also constantly increasing. The construction of aircraft carriers will no longer be short of money, we must work harder."

"When we were short of money, we did not delay the construction." Qin Tao said: "Our Mingzhou Group has never said anything about the navy and will fully support it. By the way, we must also pay close attention to the carrier-based aircraft."

“Carrier-based aircraft? Aren’t they all there?”

“Why do we already have them all? We still lack a dedicated ten-ton helicopter.”

“The project has been approved for a long time. The people in the Army are so shady that they insist on asking for part of the research and development funds from us.” Wu Shengli said: “If you are interested, let’s go and take a look.”

Although helicopters are also aircraft, they are not dominated by the Air Force, but by the Army. After all, the main equipment of the Army Aviation is armed helicopters. Among the three services, the Air Force and Navy can wait, but the Army cannot wait.

However, developing a new aircraft requires a lot of money, so the Army also finds ways to take money from the pockets of the Navy and Air Force.

Qin Tao nodded: "Okay, I need to stay away from the center of the storm recently. It would be good to go and see our helicopters. If appropriate, our Mingzhou Group's transportation company can also buy a batch."

"Yes, you can also purchase it. With your funds, the research and development of this helicopter will be faster." Wu Shengli said: "However, you have already helped a lot. If Tianjiao Aviation hadn't taken the lead in developing the vortex shaft engine, our helicopter will have no engine.”

 “No engine?”

“Yes, we originally planned to purchase it from the Maple Leaf Country, but we recently received an official notice that the Maple Leaf Country will no longer provide us with turboshaft engines for helicopters. Without your backup plan, they would be really blind!”

 Domestic helicopter R&D and production units are mainly distributed in two places, one is the Old Northeast Industrial Base and the other is in Porcelain Capital. However, the Army's main Z-Twenty was still developed in the Old Northeast Industrial Base.

 Ha Fei.

 At this time of year, the climate in Old Northeast is the most suitable.

 The refreshing wind blew on the tarmac of the airport, where several people were waiting.

“Leader Wu, you are welcome to inspect. Mr. Qin, are you here too?” The receptionist was surprised: “Hello, Mr. Qin, my name is Deng Hui, the chief designer of the Zhitwenty Project.”

“Mr. Deng? With you, the Zhi-Twenty Project will be a success immediately. Our navy and our Mingzhou Group are still waiting for it.”

Deng Hui didn't realize the meaning of the last words, but after hearing the previous words, he spoke modestly: "Mr. Qin, I really don't play a big role in this project. The main thing is that you are the main force for the people you brought back. , I even want to give up my seat to him.”

 “The person I brought back?”

"Yes, Oscar brought back from the Rainbow Country, he also brought over a dozen people. They are all helicopter professionals, and they have solved many of our technical problems. Over the years, we have been imitating, and we have also It has never been designed independently, but these people have done a great job."

Oscar?

Qin Tao thought about it for a long time before he thought of something. When he went to the Rainbow Country, he was fooled. If these Boers were not happy living there, they had to change places. Qin Tao's sincerity touched them, and they followed him.

 After arranging these people, Qin Tao forgot about this matter. After all, Qin Tao had too many things to deal with, but he did not expect that Oscar would actually become the main force here.

 Wrong!

“I remember that I promised Oscar to research armed helicopters.”

"Yes, Mr. Qin, you are right, but later, after some research, we decided to develop a ten-ton general-purpose helicopter first. When this helicopter is developed, the armed helicopter will also have a technical foundation. After all, The Wuzhi-10 we planned before was only six-ton ​​class, and its performance was completely incomparable with that of the ten-ton class."

After the military parade in the 1980s, the old leader announced to the outside world that the army would be reduced by one million, and also announced the formation of the Army Aviation Corps. Since then, the Army has been equipped with flying iron wings. However, at that time, the Army did not have many helicopters at hand.

The only one with advanced performance is the Z-9, which is a four-ton helicopter. For a long time, the Army could only install this helicopter with short wings and mount missiles. Because it only has a load capacity of one ton, it It can only carry two anti-tank missiles on one side at most. This firepower is extremely weak and cannot be compared with the Western armed helicopters loaded with sixteen anti-tank missiles and rocket launcher nests.

The Wuzhi-9 is only a temporary replacement solution. The Army also needs specialized armed helicopters. Therefore, in the 1990s, the idea of ​​Wuzhi-10 was put forward.

According to many accounts, this armed helicopter was designed by the Kamov Design Bureau. After completing the preliminary design, it was handed over to the 602 Research Institute for continued research and development. Finally, Changhe and Hafei were responsible for the assembly. There are also more than 40 domestic manufacturers. Joint assembly.

However, even with the help of the Kamov Design Bureau, the development of this helicopter is still very difficult. The most important problem is power: there is no suitable engine, no suitable rotor, and no suitable engine-to-rotor transmission system.

Engine technology is solved through outsourcing. Maple Leaf Country is a big country in the field of turboshaft engines. They quickly chose their Pratt & Whitney PT6C-76C turboshaft engine, which has a power of about 1,200 kilowatts, which is almost enough. Next is the self-developed composite rotor and corresponding transmission system.

However, these are still under development, and the Navy and Air Force have received requests for ten-ton utility helicopters. The Army is also interested. Whether it is Apache or Mi-28, etc., they are all ten-ton class. We If you build a six-ton ​​one yourself, you will obviously not be able to compare with it. Both the bomb load and the protective power will be greatly improved.

Just like that, the Army also joined in, so the Air Force just gave up the idea. You, the Army, will do it yourself and leave it to you!

In this way, the Zhi-Twenty became a research and development project of the Army, and the W-Zhi-10 was temporarily put on hold. All the technical personnel who developed the W-Zhi-Ten came to work on the Zhi-Twenty.

"The biggest problem we are researching is the engine. We originally coordinated with the Maple Leaf Country and planned to import their engines. However, the world has changed in recent years. It is normal for them to stop supplying us with engines. Moreover, we also have We need a more reliable source of engines." Deng Hui looked at Qin Tao: "Mr. Qin, Tianjiao Airlines has solved our big problem."

“The engine of Tianjiao Aviation is still in pre-research, right?” Qin Tao said: “It may not be able to catch up with the experiment, and if there is an accident during the experiment, it may be delayed.”

“No, we have already started building the prototype, and it performed very well in the bench test.” Deng Hui said, “Mr. Qin, don’t you know?”

 Qin Tao really didn’t know. At that time, they just established a joint R&D institution with Motor Siq Company. Later, Qin Tao never asked about it again. Unexpectedly, it has come out now.

"In the past few years, our aero-engines have been progressing smoothly. Turbofans have begun to be installed on trucks, and helicopter engines have also caught up with this trend." Deng Hui continued: "Our turboshaft engines are making rapid progress. It can already output 1,600 kilowatts of power on the bench, so we can definitely use this engine when our Z-20 makes its first flight."

 At the beginning, the rigid requirements put forward by Qin Tao were output power and weight, followed by fuel consumption. Now it seems that the output power has reached the standard.

 “Where’s the weight?”

"After using a lot of new materials, the weight has reached the target of more than 200 kilograms, and the power-to-weight ratio has reached 7." Deng Hui introduced Qin Tao while leading everyone to the R&D department. When they entered, You can see the frame of an airplane.

This frame is similar to that of the Black Hawk, with only slight differences in appearance. The front windshield is replaced by two pieces. At this time, a large number of people are busy on it, not only oriental faces, but also people with white skin.

One of them raised his head, looked outside, and planned to continue working with his head down, but when he saw Qin Tao, he was suddenly stunned.

“Oscar, look who’s here?” Deng Hui shouted: “You don’t want to show your face either. I originally planned to take you with me to greet the guests.”

 Oscar was unwilling to do anything unrelated to work. Reception and other receptions were a waste of time. He only wanted to work on technology. But today, after seeing Qin Tao, he immediately put down his work and strode over.

 “Mr. Qin!”
