ps: The second update is coming.,Slightly introduced some information.,But the whole chapter is about 4800 words.,It should be okay ^_^.

The main plane, located in Europe, Germany, has a developed economy and a rich society, which is a good country with a beautiful environment and picturesque scenery, and made in Germany is famous all over the world for its excellent quality and super high price.

Of course, when it comes to Germany, it is also interesting to analyze its development ideas, the whole of Germany relies on small and medium-sized enterprises for survival and development, and from the national policy, it is responsible for supporting the growth of a large number of small, medium and micro enterprises. Therefore, unlike the tax model of the Stars and Stripes Republic, the Wakos, and the European France, which rely on large-scale conglomerates, more than 70% of Germany's tax revenue comes from small and medium-sized enterprises and their related industries.

And their small and medium-sized enterprises involved and concerned about the direction is very special, different from the southern region of the Yanhuang Republic to carry out a large number of labor-intensive light industry, such as Guangdong's textile industry, Foshan's lighting industry, etc., through the scale of cost reduction of the development of the development model, German small and micro enterprises focus on special industries of enterprise-level market segments, especially the manufacture of special equipment and special mechanical parts.

Because the world's demand for this product is very small, so after a period of maintenance and development, German small and medium-sized enterprises can be said to be each enterprise monopolizes a small market, and through years of technical reserves, artificially set up a very high entry threshold, many competitors after calculation, found that the high cost of entering a small market and the low income after entering, had to make the decision to give up the entry, so that after decades of hard work, accumulation and maintenance, German small and medium-sized enterprises live quite comfortably.

Of course, the good life of small and medium-sized enterprises in Germany is really thanks to globalization, because if it were not for globalization, so that orders for special equipment and special parts from all over the world gathered in Germany, only by virtue of orders from Germany's own domestic factories, then most of the family-workshop manufacturing small and micro enterprises hidden in remote towns and villages in Germany would have gone bankrupt long ago.

In later generations, in Wang Fan's main plane, the Germans once had such a sentence: "Yanhuang is the world's factory, but the world's factory is made by us!" This also shows the confidence and glory of the Germans in their mechanical engineering. Of course, Germany has a lot of problems of its own, for example, because of high welfare, two-thirds of the people in Germany do not work much, or even if they work, they can't create much value and wealth, and the whole country relies on the one-third of the people to create a large amount of wealth, so the development idea chosen by Germany is to manufacture more high-end, more sophisticated, more automated equipment, improve the work efficiency of a few people, and produce machine products that other countries do not have, or you have me, so as to maintain the core competitiveness of their own country in the world.

The secondary industry relies on the manufacturing industry to survive, and in the manufacturing industry, the machine tool is the standard and symbol of the level of a country's manufacturing industry. Among them, the highest level of machine tools is the five-axis linkage CNC machine tool system, in a sense, reflecting the level of industrial development of a country. So what can the five-axis linkage CNC machine tool do? In today's society, if you want to solve the processing problems of impellers, blades, marine propellers, heavy-duty generator rotors, steam turbine rotors, large diesel engine crankshafts, etc., five-axis linkage CNC machine tools are the only means.

The five-axis linkage machining center established with the five-axis linkage CNC machine tool as the core is generally divided into two kinds of vertical machining center and horizontal machining center, the most effective processing surface of the vertical machining center (three-axis) is only the top surface of the workpiece, and the horizontal machining center can only complete the four-sided processing of the workpiece with the help of rotary worktable. At present, only the five-axis linkage machining center has the fastest processing efficiency and the highest machining accuracy, which can make the workpiece complete the pentahedral processing at one clamping.

Therefore, it is not difficult to imagine why this machine tool system will have a decisive influence on a country's aviation, aerospace, military, scientific research, precision equipment, high-precision medical equipment and other industries. At the end of the last century, the Japanese company Toshiba sold several five-axis CNC milling machines to the former Soviet Union, and as a result, the propulsion propellers used by the former Soviet Union to manufacture submarines were suddenly raised by several grades, so that the sonar of the butterfly ships of the Stars and Stripes Republic could no longer listen to the noise of the Soviet submarine propellers, and it was extremely shocking. After Toshiba's deal came to light and was known to the Stars and Stripes Republic, it severely punished Toshiba for violating the embargo policy on strategic materials, that is, Wang Fan's main plane in the 80s and 90s of the last century, the world's famous "Toshiba incident".

Siemens Maschinenbau can be said to be the essence and leader of German manufacturing. Siemens has 48,000 research and development professionals worldwide. Large-scale R&D centers in Berlin, Erlangen and Munich. The annual scientific research expenditure accounts for more than 10% of the company's total business and about 1/3 of the total scientific research expenditure of the German electrical industry. This explains why Siemens continues to be a global leader in new technologies.

Today, a white traveler came to Berlin, Germany, and his passport showed that he was a male citizen of the Stars and Stripes Republic. Instead, I carried a backpack and found a café near the headquarters of the Siemens Research and Development Center in Berlin, and sat for 2 hours.

"Wang Fan, what are you doing here?" Yadi asked in Wang Fan's brain.

"Hehe, Yadi, what are they doing now after we gave the space shuttle to the country last time?" Wang Fan smiled lightly and asked rhetorically.

"What else can I do, I will definitely gather experts in power and materials from all over the country to analyze, study and imitate the space shuttle." Yadea said.

"Yes, but although we provide them with a lot of information, but they don't have enough precision processing equipment and material manufacturing equipment, Yan Huang has an old saying, 'a good woman is difficult to cook without rice', there are no design drawings but can't be made, those scientists and engineers are afraid that it is even more uncomfortable!" Wang Fan said.

"Well, to paraphrase one of your famous sketch actors, 'That's pretty uncomfortable, it's all holding back there!' Yadi, who was becoming more and more proficient in using the witticism of the earth, suddenly popped up again.

"Hmm~~" Wang Fan, who was shocked by Yadire's words again, shook his head, and then said, "I plan to purchase a lot of things in China this time, although I have prepared a large amount of gold, but it is estimated that the Ministry of National Defense will definitely tentatively propose, can we buy the processing equipment and materials and equipment in our hands, hehe, in fact, they don't know at all, we have some equipment, but the technology is too advanced to dare to give, as soon as I give it, I am afraid that alien technology will be exposed, exposing many of our secrets, Other processing equipment doesn't have it at all, it's all copied from the kernel! ”

"So what are you going to do?" Yadi asked.

"Isn't this ready-made!" Wang Fan glanced at the Siemens R&D Center in Berlin, which was not far away, and continued: "There are a lot of good things there, I remember when I checked the information, they have a super large turn-milling compound machining center here, which can reach 6000mm in length and 1070mm in diameter, and can completely process large workpieces with a diameter of 1,070mm." In addition, it is equipped with a high-tech 3D CNC system specially developed by Siemens for processing large workpieces - Siemens ShopTurn3G. The size of the processed workpiece can reach 6000mm on the X-axis, 4200mm on the Y-axis, 2000mm on the W-axis beam and 1500mm on the Z-axis ram stroke, that is to say, this set of equipment is basically developed for the manufacture of large workpieces in the aerospace and machine tool manufacturing industry, and I remember that the maximum workpiece weight of this machining center can reach 40 tons. Coupled with the intelligent tool management system, it can manage up to 313 knives and automatic milling head, tsk, good thing! ”

"So your plan is..."

"Yadea, go to the core!!" Wang Fan said shamelessly.

“…… I'm not Emerald Flower!! ”

The next day, Yan Huang Dasa Northwest Space Agency.

The Yanhuang National Space Administration is responsible for domestic civil space management and international space cooperation. The main internal institutions are: the Integrated Planning Division, the Systems Engineering Division, the Science, Technology and Quality Division, and the External Affairs Division. Among them, the Department of Systems Engineering is responsible for organizing the demonstration of major aerospace scientific research projects; Responsible for managing, coordinating and supervising the development, production and testing of major aerospace scientific research models.

The director of the 705 Institute, surnamed Xing, is now staying at the Jiuquan Satellite Launch Center with the cadres and workers of the institute, and together with experts and professors from other institutes in China, he is analyzing and studying the space shuttle that Wang Fan gave to the country last time.

Since Wang Fan threw the space shuttle at the Jiuquan Satellite Launch Center in Jiuquan, it has been a place of chickens and dogs, and it has been very lively. Not only has the alert level of the nearby military region been maintained at the "red alert," but within a few days, all the technical experts in Yanhuang who had anything to do with aerospace rushed to Jiuquan by plane with their closed disciples and rolled up their covers, and they did not leave after taking root.

"Mr. Xing, how is the research?" Mr. Xing, who was standing next to the space shuttle and thinking in a daze, suddenly heard someone calling him from behind.

"Huh? It's Yan Lao, alas~~~ It's not going well, there are too many key nodes on the road to imitation!! Seeing that it was Shen Fei's "pillar", Chief Engineer Yan and President Xing said with a wry smile.

"Oh, those aspects?" Yan Lao had just come out of the F22 and F15 warehouses in the secret military base, and he didn't know much about the latest market, so he asked.

"Although we have the design drawings (the CD provided by Wang Fan), these days also through the analysis of the functional components of each component, basically can do the knowing, but only stay in the design drawing stage of knowing what each component is for, really want to imitate the space shuttle, at least there are a few thresholds that can not be bypassed, the first is the body material, from the performance parameters provided by those discs, than the Stars and Stripes Republic, the performance of the ceramic alloy applied by the "Endeavour" space shuttle has been directly improved by an order of magnitude, This is not a two-fold or three-fold gap, but a ten-fold performance gap, and it is not an exaggeration to say that it is a material revolution! But we don't have their material technology and material production equipment in our hands, and I can't cut a piece directly from the space shuttle and go to the laboratory to do chemical threshold experiments, so I can't start! The second is the engine, which is really a good thing, more advanced than the engine we expected in the concept map of the future aerospace aircraft, and I estimate that the engine field is at least 40 years ahead of us! The third is the battery, their on-board battery stores energy for electromagnetic guns and laser cannons to squander at will, we have calculated that the discharge capacity of the same volume battery is more than 120 times the level of the latest military battery in our hands, which is simply unbelievable! Hearing Chief Engineer Yan's question, Mr. Xing snapped his fingers and said one by one.

"Hehe, if you dare to really cut off a piece of the outer skin material, I guess before you can take it back for research and testing, you will be pulled out by the people of the space agency to unload eight pieces, I don't see that now the space agency is protecting this plane, and the eyes are red, for fear that any researcher will accidentally break the space shuttle, they really think that the space shuttle is paper paste, and it will be broken when you poke it!" Yan Lao smiled and said, "But the engine, there is really no way, we just completely ate the turbofan engine developed and produced by Rawls and Royce in the 60s of the last century in Britain a few years ago, but now people have already produced several generations of new products, and the gap is very big!" As for the battery, I haven't done much research, so I don't know how to evaluate it. ”

"Huh? Doesn't the engine work? I heard that Kunlun and Taihang engines have been successfully rolled off the assembly line and put into production? Mr. Xing, who didn't know much about fighter jets, asked.

"That's for publicity, although Kunlun Taihang is equipped with troops, but there is still a big gap between the service life and foreign products of the same type, only about half of their life span! And if it is only a life problem, it is better to say, the most feared is the quality problem, many aircraft units equipped with Taihang engines have reported that during the service life of the engine, the engine blades have different degrees of cracks! Chief Engineer Yan sighed and replied.

"It's the same as the space shuttle engine, it's still a matter of materials!" Mr. Xing said with emotion.

"The material is the most important aspect, but in addition, the precision of the processing equipment is not enough, and the blades of the Taihang engine are too ineffective and worn in use! This is also one of the important reasons for the cracks in the wear and tear of its blades! Yan Lao, who often deals with the engine research institute, patiently explained.

"These are not because of the Batumi embargo, let's go abroad to visit foreign advanced processing and manufacturing plants, they can let us touch at will, let us look at it at will, and even let them operate it themselves, but as long as they mention procurement, they will innocently say that we also want to sell, but Batumi won't let us!" Mr. Xing, who also had deep feelings in this regard, said approvingly.

"It's better to ask for others than for yourself, you can continue to watch, I want to talk to Lao Gao of the equipment department first, and see what good things he has in his library!" Yan Lao waved his hand and strode towards the temporary office of the senior deputy director of the General Armament Department.

"Slow down, then!" Mr. Xing said goodbye politely.

Five minutes later, Deputy Minister Gao's office.

"I said Lao Yan, what kind of wind blew you here from the cave in the ground?" Seeing Chief Engineer Yan, Vice Minister Gao was a little surprised and asked.

"Those few (alluding to the F22 aircraft, afraid of leaks) we have studied for a period of time, and now it can be said that we have mastered some parameters, such as the infrared signature data of the tail engine, etc., and in the future, the reconnaissance of these aircraft and the discovery of the enemy will play a lot of roles, but if you want to further absorb and imitate, we can't bypass the material manufacturing process and high-precision processing equipment anyway, I don't want to ask you if you have any good ways, only to know that the country has recently had such a big thing, Even the space rescue was successful! Yan Lao explained.

"yes, you've been lying there these days, and you're not very well informed!" Vice Minister Gao replied.

"I said, Lao Gao, the propaganda says that this space shuttle was made by us, why did I get to Jiuquan, and the high-level people secretly greeted me and told me that I bought it, who sold it to us? Old Maozi? Unlikely! Yan Lao, who had always been puzzled, asked.

"This is top secret, you can't say it, don't ask!" Hearing that Elder Yan asked about the "minefield", Vice Minister Gao suddenly turned straight and said solemnly.

"Understood, understood! Then I won't ask, I came to you this time, just to ask, you help me check, to see if the research institutes and research institutes under your ministry have made progress in processing equipment, and now the aircraft research and imitation over there needs some equipment support! Yan Lao thought of the purpose of his visit this time and asked.

"Well, I understand, I'll go back and ask you!" Vice Minister Gao was talking, when suddenly his mobile phone rang, and when he saw that the caller ID was his top boss, he quickly pressed the answer button and said, "Chief, are you looking for me!?" ”

"Lao Gao, hurry back to Beijing, the seller is calling!"
