The May 9th transformation work in the base area has very important reference and reference value for the country. It can be targeted in future transformation and new tank design, avoid many detours, and save a lot of research funds and time, so I heard that it is The experts were unwilling to fly to the airport, but stayed in the military research institute to conduct more detailed and in-depth data analysis. Guan Fei did not force himself, so he returned to the new city with only the accompanying security personnel and members of the base expert team. ¡°He came in a hurry to meet with the second batch of domestic military delegations to discuss joint establishment of domestic factories, as well as technology transfer matters such as turbofan six engines and J-9 fighter jets. This is a major event for the base area to obtain first-hand military research information and lay the foundation for independent military research in the future. Of course, he does not dare to miss it. The military leaders who led the delegation this time were no longer sent by the Second Ministry, but were led by the National Defense Science and Technology Commission, with assistance from the Third, Fourth, Fifth and Sixth Machinery Departments. The reason is also very simple, because the largest number of military factories are affiliated to the Ministry of Ordnance Industry (Fifth Machinery Department), followed by the Fourth Machinery Department (Ministry of Electronics Industry), the Third Machinery Department (Aviation Industry), the Sixth Machinery Department (Shipping Industry) and General Logistics Department. The leading agencies of these ministries and commissions belong to the General Assembly and the Military Commission respectively, and they implement dual leadership. On the Military Commission side, the leading agency responsible for military industry is the National Defense Science and Technology Commission. The leaders were Vice Minister Luo from the Commission of Science, Technology and Industry for National Defense, and two division chiefs from the Third Machinery Department and the Fourth Machinery Department, together with Director Chen from the General Assembly Department, Director Liu from the General Logistics Department, and Director Tan from the Fifth Machinery Department who had come here before. and others, formed a new delegation. The original delegation was disbanded on the spot. Minister Xia Zhongyuan completed his task and led other members back to the country. All subsequent progress was handed over to the new delegation. In the Military Command Department, he met Deputy Minister Luo and a director surnamed Wang from the Third Machinery Department. The base area also attaches great importance to it, led by Guan Fei himself, Zhang Shengguo, head of the civil affairs department, and Sun Yaohua, deputy commander, also attended. At the same time, Cui Guodong, deputy director of the newly established Military Industry Bureau, Miao Wei, party secretary, and director of the Power Research Institute and power Wei Liqun, director of the department, Zhou Xiaoshan, president of the Industrial and Mining Enterprise Group, and heads of relevant departments of the researchers who participated in the improvement work of the 59 tank participated in the meeting. In the large conference room, both parties took their seats after exchanging pleasantries. After taking his seat, Guan Fei first expressed his gratitude for the domestic support for the base area. Zhang Shengguo and Sun Yaohua also expressed their gratitude to the domestic support on behalf of the civil affairs department and the military. The delegation members all enjoyed the sincere thanks from the three giants in the base area, nodding and smiling, and the atmosphere between the two parties was very harmonious. Then the two sides got down to business. Vice Minister Luo, as the head of the delegation, said: "Last time, Minister Xia Zhongyuan reported to Commander Guan that he wanted to purchase fighter jets. We made a comprehensive report to our superiors. In terms of our bilateral relations, , should not be rejected. However, considering the international and domestic situation, selling fighter jets is still too sensitive, so we decided to copy the original design and manufacturing drawings of the J-9 and turbofan six engines and transfer them to you.¡± Zhang Shengguo, Sun Yaohua and other base area cadres were very disappointed when they did not agree to sell fighter jets. However, they were overjoyed when they heard later that they were willing to transfer the design and manufacturing drawings of the J-9 and Turbofan-6 to the base area. Although in order to maintain discipline at the meeting, they were overjoyed. There was no whispering to each other, but everyone looked happy and looked at each other, showing the joy in their hearts. Only Guan Fei, Wei Liqun and other cadres engaged in technical work smiled and were noncommittal. ??The technical drawings are based on the vehicle skin, including the most basic screws and other parts. The total number of drawings is no less than hundreds of thousands. Generally speaking, it would take several months just to look through so many drawings. If you want to understand them thoroughly, it would take five or six years! ¡°It¡¯s not unusual to spend more than ten or twenty years on it. ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Instead of selling off-the-shelf aircraft and production lines, we hand over two products that have been discontinued and have not yet been finalized to the base area. On the surface, they look sincere, but they don¡¯t have much value. The base area can't turn the blueprints into physical objects in the short term, let alone equip them into an army, so it doesn't make much sense. While Minister Luo was speaking, he was also observing the expressions of Guan Fei and others. In his opinion, the cadres in these base areas are too young. They are all in their twenties, and the oldest is less than thirty. They are so young that he is jealous. Judging from the actual contact just now, although Zhang Shengguo and others have been in high positions for several years and have a much calmer demeanor than ordinary young people, they still couldn't help themselves when they heard that the country had agreed to transfer the J-9 and Turbofan-6 blueprints. Happy and happy. Only Guan Fei still had a gentle smile, he was neither impatient nor impatient, showing more patience than others, and he couldn't help but nod secretly. Guan Fei expressed his gratitude again, then looked into Minister Luo's eyes, and slowly said: "Through our connections, we obtained the survey drawings and performance data of the American F4O4" "What did you say?" He said in a low voice , it was like a thunder in the ears of Minister Luo and others, making them dizzy in an instant. They were so frightened that they forgot their politeness, stood up at the same time, and exclaimed. Guan Fei smiled slightly and said calmly: "I mean, we got the mapping drawings of the American F4O4 engine, as well as the specific parameters and performance of each component. But even though we got this information, our abilities are limited and we are unable to understand it thoroughly. So. We plan to invite domestic parties to join us in copying it. I wonder if you have any intention in this regard? " "Yes! Of course!" "Haha! I've heard of the name of f4o4 for a long time. Yes, it is said that this is a high-performance medium-thrust engine. We have always wanted to see it, but we have never been able to get the relevant drawings. I didn¡¯t expect that you actually got it. Hahahaha, this is where you will find nothing. It takes no effort at all!¡± Minister Luo and others, who had just pretended to be sitting firmly on the Diaoyutai, looked ecstatic at the moment. Looking at their expressions, they would have almost been unable to hold back if they were not in the conference room. Dance a bit. Zhang Shengguo and others looked at each other and smiled. It turns out that the country also has something to ask for! "Can I get the F1oo used in the F15 fighter jet? If not, the F11o will work too!" Minister Luo asked, his face flushed with excitement, and he was still a little dissatisfied. They don¡¯t care how Guan Fei got it. It has long been known in China that Guan Fei has a very efficient technical information network and can obtain some very advanced and latest technologies from time to time. In the early days, the base area was weak and Guan Fei's power was not great. He Tao and others who had contact with him in the country were curious and wanted to inquire about it, but he smiled and ignored him every time. With the expansion of the base, Guan Fei no longer had to beg for help for a few tons of rice, and the country gradually stopped seeking to share this intelligence network. As long as he could get a piece of technical information from him every now and then, , that¡¯s enough. With these past examples, now that Guan Fei said that he had obtained the information on f4o4, Minister Luo and others did not doubt that Guan Fei was trying to deceive people by making false claims and exaggerating his own worth. Instead, they fully accepted its authenticity at the first opportunity. , immediately jumped up with excitement. "If it were more than ten years ago, they wouldn't be so out of control. As early as the 1950s and 1960s, any aircraft or engine that was available in foreign countries could be copied in China. For example, in the 1950s, it was possible to imitate World War II-level aircraft and engines, and in the 1960s, it was possible to imitate Soviet fighter jets and engines in the 1950s. At that time, the country felt that it was only ten years away from the world's aircraft and motivation. As long as we work hard and spend another ten or twenty years, it will not be difficult to catch up with and surpass the United States and the Soviet Union. But since the 1970s, this ambition has gradually faded. One J-8 and one J-9 are all based on the J-7. As a result, after so many years, the J-8 can only be said to be able to fly, but its performance is far from meeting the requirements. The J-9 is even worse. So far, it only has one ground verification aircraft. The motivations for their matching have been studied for more than 20 years, but now the results are getting further and further away from the requirements, and the possibility of realization is becoming increasingly difficult to see. Take the turbofan six as an example. The latest sixth-generation turbofan, the paper data is still very good, the intermediate thrust is 8300 kilonewtons, the afterburning thrust has reached 13800 kilonewtons, nearly 14 tons, and the thrust-to-weight ratio has reached seven. Compared with various advanced engines in the United States, this data is not much different. It looks very beautiful. But what is the actual situation? Based on the technology of this era, the service life of domestically produced engines is usually one hundred hours, while the service life of turbofan six is ??less than two hundred hours, only eighty hours. Then, in order to meet the requirements of the Air Force, the inlet temperature was forcibly raised. As a result, the lifespan was sharply reduced to less than thirty hours! ? ? What¡¯s the use of such a short overhaul life! What¡¯s even more annoying is that in order to achieve such an indicator, the engine is constantly patched and the weight is constantly accumulated. The total weight of the latest turbofan six modification has reached two tons! "Two tons of motivation, have you heard of it?" You think you are burning a boiler! The American F4O4 with the same thrust has an overhaul life of 1,000 hours and only weighs 983 kilograms. The difference between the two sides is more than double! With such a motive, it would be unreasonable not to dismount! As long as there is still a little hope, even if the military tightens its belt, it is impossible to reject the turbofan six, which has already produced a prototype. If military spending is abundant, for the purpose of training the team, let the project continueIf we continue this work for another ten or eight years, we may be able to make progress and develop a strong research team. But the key point is that the military has no money, and they are so hungry that they have to beg for food, so how can they have any money to burn! ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Otherwise, the first domestically developed engine like the Turbofan VI, would be willing to give it to the base area for free? It is precisely because of the unsatisfactory motives of his own that the country has become increasingly anxious and considered purchasing from abroad. But the United States is not an internationalist fighter. What it wants is for China to hold back the Soviet Union. It is hard to say whether it will be an enemy or a friend in the future. It is impossible to sell advanced technology to China. ????????????????????????So the country is drooling when looking at the various advanced motivations of the United States, but it is what they want. Now that I heard that Guan Fei actually got the survey drawings and dimensional data of f4o4, everyone jumped up like firecrackers being lit. "Are you telling the truth?" Minister Luo stopped putting on airs and rushed up, grabbing Guan Fei's hand and asked eagerly. "That's right!" Guan Fei gave him an affirmative reply, "I heard that Turbofan 6 has been discontinued, so I had an idea. I thought these researchers have been engaged in engine research for more than ten years and have rich experience. It is really difficult to disband the team now. It's a pity. If it's convenient, we might as well come here and work together to try to replicate this engine. Although we have no experience in engine research, we do have some unique strengths in metallurgy and precision processing. It's just right for both parties to cooperate and learn from each other's strengths. It depends on whether you are willing. "Of course we are willing!" Minister Luo was so excited that he agreed without thinking. For the latest book update address, please click Yunlai.ge to get the latest chapters of this book.
