Chapter 826: Wu Daguan's Triumph

Although Tan Zhenhua instigated the "Flying Leopard" fighter, which is currently only a full-size metal model, out of the tongue like a spring, Chen Yijian, a mature and respectful man, can also bring a lot of confidence to people, but Xie He is still Could not make up the determination to buy this type of fighter.
In fact, this is not difficult to understand. Arms purchases, especially such huge arms purchases, have never been a simple matter, involving politics, economy, international relations and other aspects, and the current state of this type of fighter is far from being discussed. It is mature, it is only a model after all, and the habit of the princes of the Middle East, they always like the spot...
Therefore, Chen Yijian and Tan Zhenhua only got a promise that Sheikh would consider carefully.
Such a result is neither good nor bad. Of course, Tan Zhenhua did not expect to be able to make the decision to purchase the other party through a brief introduction, and can take down 5 Alian Emirates airliners through a few days of "escort" This is enough to satisfy him.
And the reason why he invested heavily in the research and development of "Flying Leopard", the first goal is not to sell aircraft...
Prince Sheikh stayed in Xijing for a few more days. After fully appreciating the long history of China and the breadth and depth of food, he left with satisfaction. He had to return to the country to report to the President and his father, the Prime Minister. As a result of the official visit, Tan Zhenhua stayed in Xijing because someone was returning.
Wu Daguan did not come back alone, but a large number of people came to Xijing with him, and Tan Zhenhua even saw several foreign faces among them.
Father, this is a triumphant return with the beaten drum!
As Tan Zhenhua spared no effort to blend in, the "Flying Leopard" fighter did not toss like his previous life. The entire development process was orderly and staged and the results were gratifying. As a result, the "Speey" was once interrupted. "The localization process of the MK202 engine has also been put on the agenda again; moreover, as the process of the London negotiations continues to be passed back to China, the senior leaders of China have finally realized that the imported "Speey" technology and production process are It's a little behind, but for China's current industrial base, it happens to be completely digestible, assimilated, and mastered.
What's more, Tan Zhenhua also showed to the leaders of China how much potential the "Speey" engine can tap by constantly digging out the good things of Rolls-Royce.
"At present, the agreement reached with Luo Luo is divided into three main parts." In a small conference room of Xijing Engine Factory, Wu Daguan enthusiastically summarized several core personnel of the project: "First, introduce the full set of MK606 technology and localize it; second, work with Rolls-Royce to complete the follow-up research and development of TF41912-B52 and conduct localization; third, work with Rolls-Royce to develop RB168-Mk807 ​​to increase the afterburner model The research and development and localization of the engine; among them, the general manager of the Gas Turbine Institute will be responsible for all the engine development parts, and Comrade Liu Daxiang will preside over this work, and the general manager of Xijing Engine Factory will be responsible for all the problems related to the production process. Comrade Li Mengzhen is in charge of this work. Comrade Meng Zhen, let's talk about it first. You are most familiar with this series of engines."
Following his words, a middle-aged woman in her forties stood up and said: "Wu Lao, Mr. Liu, Mr. Tan, during the negotiation in London, I was combining our factory. A Spey battle" and the experience and lessons learned from visiting Rollo during this period of time. I reviewed the production and assembly process of the entire engine, and I will report it to everyone now."
"All of you here should be familiar with the fact that the first Spey battle started in 1976. The first thing that year was the trial production of "Speey" engines using imported raw materials. To this end, our factory compiled more than 420,000 copies. Technical data, more than 30,000 sets of special process equipment drawings, and the country has also mobilized the nation's strength to carry out the localization of metallic materials, non-metallic materials, finished accessories and large forgings. It is really a vigorous movement."
When Li Mengzhen said this, there was obviously a blush on her cheeks. Obviously, those passionate years that were not long in the past left her very unforgettable memories.
"After the start of the battle, we soon discovered that it was impossible to complete the processing of this engine with the domestic processing equipment and methods at the time. So, under the leadership of Mr. Wu, we traveled to European advanced equipment manufacturers to purchase More than 700 sets of equipment have been installed, and 23 sets of equipment have been manufactured by itself. The latest technology including electrolytic machining, electron beam welding, metal spraying, vacuum heat treatment, pipe track welding, vacuum brazing, CNC pipe bending, precision forging, etc. And processing technology. The introduction of these new processing technologies and technologies has enabled our factory’s production technology and capabilities to jump directly to the international level in the mid-1970s. I can proudly say that among the major domestic aero engine production plants, The equipment capabilities of our factory are definitely second to none."
"But even so, we still face many problems. In summary, there are mainly a few. First, compared to the introduction of technology and equipment, I think the introduction of a quality management system is more important. This is the first time we It can be reflected in the shell battle. With the same materials and equipment, the pass rate of the Luoluo factory is higher than ours. It has to be said that they are the result of the quality management system standards of each production link. So this time I Insist on adding a quality management system team to the list of invited experts from Luo Luo to our factory."
The few people present at this meeting nodded frequently, and Wu Daguan said: "We have already asked Rollo for this one when we were in London, and they also agreed. You go on to say other things."
"This second article is about craftsmanship." Li Mengzhen said: "As a result of the last Spey battle, although qualified engines were produced, several of the key components were actually made in Britain because there are many We have not fully mastered the production technology of parts. I have calculated it roughly. There are at least more than 20 hot processing technologies and more than 20 cold processing technologies that need to be tackled. Among these key technologies, the core and the most important It belongs to the production process of engine turbine blades. The "Speey" engine has a total of 35 stages of turbines. All the blades on it must be manufactured with "no margin precision forging", and "no margin precision forging" is required. This kind of processing technology has never been done in China. Although we have bought precision forging equipment, we don’t know how to use these equipment to produce qualified products. Then in this technology transfer, I think we This technological difficulty must be overcome at all costs."
Wu Daguan nodded slightly again, and asked, "Anything else?" But he turned his eyes to look at Tan Zhenhua.
"There is another item, that is, basic materials." Li Mengzhen continued: "I simply counted. Except for the results of the successful development of the previous battle, there are at least more than 80 basic materials that need to be newly developed, and these are not based on What our factory can solve, even if we can obtain sufficient technical information from Rolls-Royce, we still need relevant domestic units to conduct sufficient experimental certification on the formulation and processing technology of these basic materials."
After thinking about it, she finally concluded: "Of course, if we can learn the lessons from the last time and implement the certification and implementation of these three items in place, I believe that our factory can reach a new level in the field of aviation manufacturing. ."
After Li Mengzhen sat down, Wu Daguan looked at Tan Zhenhua with a smile: "Zhenhua, after listening to the speech of Chief Technologist Li, do you have any ideas?"
The old man asked strangely...
Moreover, his present expression, this expression, made Mao a little familiar?
Also, why does Li Mengzhen's words that seem to be extremely reasonable just now make people feel a little weird?
Tan Zhenhua didn't answer Wu Daguan's words immediately, but carefully recalled it by bowing his head and drinking tea, hoping to find out the origin of the strange feeling in his heart.
By the way, Li Mengzhen just said that it’s a big one. The central idea is nothing more than that. In this negotiation with Britain, there are several aspects that need to be paid attention to. It is also China’s first business with Luo Luo that others were deliberate The aspects of prevarication and neglect can be regarded as lessons drawn from lessons.
But shouldn't these contents be the main battlefield for Wu Daguan and Hooker?
Taking an occasion like today, it actually doesn’t make much sense, because the only listener who doesn’t know these things is himself, and as a professional and technical blind investor in the field of aviation development, he does not know or do not know these contents. How much impact will it have on your investment behavior... Then, what is the deeper meaning of what the old man deliberately said through Li Mengzhen's mouth?
Do you still want money? If you are only asking for money, with the current level of familiarity between yourself and the old man, you don't need to be so obtuse, okay?
and so……
