Warship of Great Power Chapter 786

  Chapter 786 The research and development of H6J began in the 1970s

"Everyone in the audience, I'm very glad that we meet again. Today, the theme of our Zhang Zhong said program is Zhang Zhong said Hong Liu." Zhang Zhong also appeared on the TV screen as scheduled. In a word, Zhang Zhong said that the program is longer and the introduction is more detailed.

"We know that during this maritime parade, our navy displayed the H6J bomber to the outside world. This bomber has undergone major changes, and we are also very curious, so we immediately invited Mr. Chen, a well-known domestic aircraft expert, please He came to tell us the story of Hong Liu J."

  Mr. Chen is the chief engineer of the JH-7, so it is of course very authoritative for him to tell the story of the J-7.

"It is really not easy for the H6J to come to this day. After all, this project started in the 1970s. At that time, many aircraft designers worked hard for this bomber. It took many years. Now it can It's a real achievement, and some old people who just came into contact with this project didn't even see its heroic appearance.”

   "Started in the seventies? That is, the project has been going on for thirty years?"

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

   "Mr. Chen, please give us a detailed introduction, for example, how this project was established?"

"Back then, we had mastered the production technology of the H-6, 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 the variable-sweep wing. Therefore, we planned to improve the H-6 into a variable-sweep wing fighter. At that time, not only us We are working on this project, and other domestic units are also working on this project, for example, the 320 factory, which was working on the strong six back then, also used variable-sweep wings.”

   "Mr. Chen, H-6 uses the wing-root engine layout method. I'm afraid it's not easy to change the variable-sweep wing in this way?"

"Yes, at that time, we studied for a long time to solve the problem of the rotor shaft of the variable-sweep wing arranged at the root of the wing, but no matter how we researched it, we had no choice but to make major changes and change the engine compartment from The wing root part has been transferred to the tail of the aircraft, and I have a few design drawings at that time, you can take a look."

The design drawing appeared on the screen. The first one is to change only the variable-sweep wing. The engine nacelle at the root of the wing seems to have two corners. It is a large wing box, and the wings are installed on it. How do you look at it? awkward.

  The second picture is still the same, but the wing box is moved up to make a single-wing structure, and 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 completely changed, the engine is placed at the rear, and the intake port is moved forward.

"If you look at this design drawing, you can find its huge air intake. This design is based on the MiG-25, but in order to facilitate the mounting of weapons, the layout of the lower wing is made. It is only the shape of the body. We have been arguing back and forth for more than ten years, and it was not until the 1980s that the shape design of this aircraft was completed, and then we discovered another big problem we faced.”

"what is the problem?"

   "Engine."

"If we want this aircraft to play the performance of the variable-sweep wing, we need a powerful engine. The turbojet-8 we imitated before can't provide enough thrust at all, so we started to improve its engine again. .”

   "Improve the engine? Maybe add an afterburner to the back of it?"

"That's right, that's it. Our turbojet-8 originally only needs to propel the subsonic H-6, so we only need an ordinary jet engine. However, if we want it to fly at supersonic speed, we have to turn on the accelerator. power, so we added an afterburner on the basis of this engine."

   "The engine is our weak point."

   "That's right, back then we used the WS-8 to test the flight to verify the aerodynamic design of the airframe, and at the same time started to work on the afterburner. It took more than ten years for this project to finally succeed."

   "That is to say, our aircraft is modified from the H-6 engine?"

"That's right, it is the turbojet-8 afterburner modification. However, we also have our own innovations. For example, we have made a lot of improvements to the turbojet-8 with modern technology. The life of this engine has changed from 800 The hour has increased to 2,000 hours, the military thrust has increased by 20%, and the fuel consumption has also decreased by about 10%. If our old H-6 has not already used D-30K, we really want to use this to improve Our old Hong Liu."

   "Then this aircraft has encountered other problems during the development?"

"There are many problems. For example, when this aircraft was developed, it was aimed at future warfare. It can fly at high altitude and high speed, and can also penetrate defenses at low altitude and high speed. During the low-altitude and low-speed flight test, this aircraft almost There was an accident 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, which makes it easier to penetrate at low altitude and low speed."

   "Modern warfare is already the era of stealth aircraft, Mr. Chen, have you thought about making stealth improvements to your bomber?"

"Yes, stealth aircraft is a trend, but we can also see that stealth technology is not a panacea. In this war, stealth aircraft was defeated. Therefore, we believe that stealth aircraft is important, but long-range attack 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, so that it can launch attacks outside the enemy's defense zone."

  Zhang Zhong said that the H6J program was broadcast all over the world, and many people felt complicated after watching this program.

   "This is a joke! Do they think they can get Da Mao to distance themselves by fooling around like this? This is clearly the Tu-22M bomber. Da Mao sold this bomber to Dongfang. They have gone too far!"

   "We must let Da Mao know the consequences of doing so!"

   "They not only sell the Tu-22M bomber, but even the production line. Someone must pay for it!"

This time Zhang Zhong said that the intention of the program is very obvious: H-6 J has nothing to do with Tu-22M. We have been developing it since the 1970s, and we have been developing it until now. result!

  Anyway, let's make it public like this. As for whether others believe it or not, that's other people's business, and it has nothing to do with us.

   Tupolev Design Bureau.

   "This is nothing but blood, how can our Tupolev Design Bureau sell the information of Tu-22M to the Orientals casually!" Liv Bazenkov said angrily.

The previous chief designer, Valentin Briznuko, has retired, and the current leader in the Tupolev Design Bureau is the former assistant of Briznuko, Bazenkov, who is facing the investigation Government officials, very annoyed.

  A bomber similar to the Tu-22M appeared in the east, and then the government began to suspect him. This is clearly slander.

"Then how did the Orientals make the Tu-22M bomber? You are the designer, you should know that it is impossible to improve the Tu-16 into the Tu-22M, even if you change the Tu-22 into the Tu-22M, These are clearly two different aircrafts." The government official asked.

"How do I know?" Bazenkov continued: "When the Red Empire collapsed, not only did we have the Tu-22M, but other countries also scattered many bombers of this level. For those countries, selling this aircraft It is not impossible to change the bread. Even in our own army, there may be some people who will do this. For money, they can sell everything, not to mention the Tu-22M, even the Tu-160 Lose."

   "You mean, the H6J displayed by Dongfang is actually a refurbishment of our Tu-22M?"

"I don't know about that. It is more likely to be refurbished. After all, it is not easy to build a new bomber of this level. The aviation industry in the East is indeed developing rapidly. However, if you want to study this level of bomber, you still have to It's too late. Among other things, the engine is very difficult to produce, and it's simply impossible to transform it from the original WJ-8.”

  Government officials breathed a sigh of relief.

  The East has the Tu-22M, not only can it deal with the countries in the East, these bombers may also fly to the north, they must take precautions in advance, after all, in this era, the threat of bombers is still great.

   As for the American protests? It doesn't matter, they still care about other people's protests? If other people push and annoy them, they will be punched at most.

   "The loss of personnel in your Tupolev Design Bureau has been serious over the years. Is it possible that they will go to the East and help the East imitate this bomber?"

  The surveying and mapping imitation ability of the Orientals is too powerful, so people have to beware.

   "This is beyond our control. If we have no other projects, our entire design bureau may go bankrupt. It is not up to us to ask where our designers who have left go."

  When he said this, Bazenkov was also a little depressed.

  Things are like this, what can he do?

  Who let Da Mao down?

   East.

   "Recently, our H6J was publicly displayed and caused a sensation." Wu Shengli said to Qin Tao: "A lot of pressure is directed at the Tupolev Design Bureau."

  Qin Tao smiled: "Oh, rumors only stop at wise people. We have already announced to the public that the H6J is completely improved by ourselves. These people just don't believe it. If they don't believe it, I can't help it."

   "Well, when the white swan shows up later, what should you say?"

  The display of the H6J this time has already caused such a big sensation. If the white swan is displayed in the future, it will shock countless people even more.

  H6J is just a bomber with a maximum take-off weight of more than 100 tons, which can fly only a few thousand kilometers. The White Swan is a strategic bomber, which can fly more than 10,000 kilometers.

   "What's the matter, it's just a four-engine modification of our H6J." Qin Tao said.

  The white swan is a strategic weapon, and it cannot be shown casually, because it is more secretive. However, if it is displayed, our side will be generous. Isn't it just adding two more engines to the H-6J? What's so strange?

   "If we hadn't entered the era of stealth aircraft, it would be a good idea for us to survey and map imitation white swans." Wu Shengli continued.

   "That's right, if we had been 20 years earlier, we would have surveyed and mapped the imitation white swan. Let's forget it now. Our stealth bomber is the most important project, and the country can't support too many projects."

"After our public display this time, there was a sensation in the whole country, which strengthened our national prestige and military prestige. With this wind, our national defense lottery sold more." Wu Shengli continued: "The navy's military expenditure is also constantly increasing. The construction of the aircraft carrier will not continue to be short of money, we have to work harder."

   "When we were short of money, we didn't delay the construction." Qin Tao said: "Our Mingzhou Group has absolutely nothing to say to the navy, and fully supports it. By the way, we have to pay close attention to carrier-based aircraft."

   "Carrier-based aircraft? Don't they all have them?"

   "Why do we have all of them? We still lack a dedicated ten-ton helicopter."

   "The project was established early in the 20th century. The people in the army are too dark, and they insist on asking for a part of the research and development funds from us." Wu Shengli said: "If you are interested, then let's go and have 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 Air Force is armed helicopters. Among the three military types, the Air Force and Navy can wait, but the Army cannot.

   It's just that it takes a lot of money to develop a new aircraft, so the Army also tried every means to get money from the Navy and Air Force pockets.

  Qin Tao nodded: "Okay, I need to stay away from the center of the storm recently, and it would be good to have a look at our helicopters. If it is suitable, our Mingzhou Group's transportation company can also buy a batch."

"Yes, you can also purchase. With your funds, the research and development of this helicopter will be faster." Wu Shengli said: "However, you have already helped a lot. Shaft motors, our helicopters would have no motors."

   "No engine?"

   "That's right. I originally planned to purchase from Maple Leaf Country. Recently, I was officially informed that Maple Leaf Country will no longer provide us with turboshaft engines for helicopters. If there is no backup plan from you, they will really be blind!"

  The domestic helicopter research and development 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 main force of the army, Zhi 20, is still developed in the old Northeast Industrial Base.

   Hafei.

  In this season, the climate in the old Northeast is the most suitable.

  The refreshing wind was blowing on the tarmac of the airport, and several people were waiting there.

  "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 20th project."

   "Mr. Deng? With you, the 20th project will definitely be successful immediately. Our navy and our Mingzhou Group are still waiting."

Deng Hui didn't realize the meaning of the latter words, but after hearing the former words, he opened his mouth modestly: "Mr. Qin, I really didn't play a big role in this project. The main thing is that you will be the main force for the people you bring back." , I even wanted to make way for him."

   "The one I brought back?"

"That's right, Oscar brought back from the Rainbow Country, he also brought over a dozen people, all of them are professionals in helicopters, and solved many of our technical problems. Over the years, we have been imitating, and still It has never been designed independently, and these people have made great efforts."

   Oscar?

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

  After arranging these people, Qin Tao forgot about it. After all, Qin Tao had too many things to deal with, but he didn't expect that Oscar would become the main force here.

   No!

   "I remember, I promised Oscar to study gunships."

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

  After the military parade in the 1980s, the old leader announced to the outside world that he would disarm the army by one million and at the same time announce the formation of the Army Aviation Corps. Since then, the Army has been equipped with flying iron wings. However, in that era, the Army did not have many helicopters on 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 short wings and missiles on this helicopter, because it only has a load of one ton, so it At most, two anti-tank missiles can be mounted on one side. The firepower is too weak, and it is incomparable with the western armed helicopters loaded with 16 anti-tank missiles and rocket launchers.

  Wu Zhijiu is only a temporary replacement plan. The army still needs special armed helicopters. Therefore, in the 1990s, the idea of ​​Wuzhi 10 was put forward.

According to many sayings, the Kamov Design Bureau was responsible for this armed helicopter. After completing the preliminary design, it was handed over to the 602 Institute for further research and development. Finally, Changhe and Hafei were responsible for the assembly. There are more than 40 manufacturers in China. 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.

The engine technology is solved through outsourcing. Maple Leaf Country is a big country that manufactures turboshaft engines, and soon chose their Pratt & Whitney PT6C-76C turboshaft engine with a power of about 1200 kilowatts, which is almost enough. Next is the self-developed composite material rotor and the corresponding transmission system.

However, these are still under development, and the Navy and the Air Force have a need for ten-ton general-purpose helicopters. It's obviously incomparable to build a six-ton ​​class by yourself. Both the ammunition load and the protection power will be greatly improved.

   Just like that, the army also joined in, so the air force directly dropped the pick, and your army will do it yourself, and leave it to you!

  Zhi 20 thus became a research and development project of the army, Wu Zhi 10 was temporarily put on hold, and all the technicians who developed Wu Zhi 10 came to work on Zhi 20.

"The biggest problem we are studying is the engine. We originally coordinated with 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 A more reliable engine source." Deng Hui looked at Qin Tao: "Mr. Qin, Genghis Khan Aviation has solved our big problem."

   "Is Genghis Khan Aviation's engine still in pre-research?" Qin Tao said: "It may not be able to catch up with the experiment, and, in case of accidents during the experiment, it may be delayed."

   "No, the prototype has already started, 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, he just established a joint research and development organization with Motor Sich. Later, Qin Tao didn't ask any more questions. He didn't expect it to come out now.

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

  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.

   "What about the weight?"

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

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

  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 taken aback for a moment.

   "Oscar, look who's here?" Deng Hui shouted, "You don't want to show your face, and I planned to take you to meet the guests."

  Oscar is unwilling to do anything unrelated to work. Reception is a waste of time. He only wants to work on technology. But today, after seeing Qin Tao, he immediately put down his work and walked over in great strides.

   "Boss Qin!"
