    No way, during the Gulf War, the US military's "Tomahawk" cruise missile's highly flexible combat method, weird and inexplicable movement trajectory and final puncture-like damage effect not only beat Iraq, which has an integrated air defense system, to the ground.  , and also shocked the knowledgeable people engaged in national defense research in China.

    Because in some respects, domestic air defense forces are still not as advanced as Iraq. What should we do if we face a cruise missile similar to the Tomahawk?  Do you just have to watch this thing run amok and be beaten passively?

    Because of this, when it is not equipped with similar weapons, defense has become the top priority of the headquarters. However, this idea is easy to say. The country does not even have a clear concept of what a cruise missile is, so what?  To defend?

    At this time, the Attack-2 UAV unexpectedly appeared in the confrontation exercise between the red and blue coalition forces. Those researchers engaged in cruise missile defense saw that this was the prototype of the target missile that they had been looking for for a long time but had not found.  So before the exercise ended, the relevant report had been submitted to the head of the headquarters, and reported to the headquarters and higher decision-making levels through the head of the headquarters.

    At other times, it doesn¡¯t matter how much you save money or tighten your belt, but once it involves the fundamental security of the country, China will spare no effort to make up for this shortcoming. This was the case with the two bombs and one satellite back then, and the Target-5 cruise missile  The same goes for special target missiles.

    So after quickly passing the identification of the expert group, a large order of 2 billion yuan fell on Ascendas Group.

    This is why, compared to the general production of other aero-engine factories, Ascendas Aerospace Power Company¡¯s wd-30s turbofan engine production cluster around the No. 0 assembly workshop is so busy.

    Five hundred sets of turbofan engines supporting the target-Type 5 cruise missile special target missile, plus one hundred spare engines, a total of six hundred sets.

    You must know that this is not a bicycle or a sewing machine. Once the production line is opened, it rolls off the assembly line like water, and orders can be digested in half a year. It is an aerospace engine, and it is also a high-performance small turbofan engine. Every one of them  The components are comparable to industrial works of art, all processes are cutting-edge, and the production cycle is calculated on a monthly basis.

    Apart from anything else, the outermost casing of the entire aeroengine is considered to be relatively simple in terms of technical level among all components, but even such a simple existence requires the preparation and processing of lightweight alloy materials or composite materials; overall molding; and electron beam processing.  Or laser welding and other processes and manufacturing technologies, after a series of production steps, it will take at least about 20 days to produce a fully processed receiver.

    This is still simple, but difficult ones are like the fan with external duct, which requires titanium alloy to wrap the honeycomb structure to form a curved shape that is conducive to air flow.

    This involves processes and manufacturing technologies such as metallurgy, composite materials, heat treatment, precision machining, etc. Every step must be careless, and you can't even get up quickly if you want to.

    As for the hell-level turbine blades, not to mention, it has been a very tortuous journey from the beginning of metal smelting.

    Because of this, the production cluster of Tengfei Aviation Power's WD-30S turbofan engine seems large to outsiders, but in the eyes of several knowledgeable leaders, it still feels a bit small. After all, with the ultra-long production cycle of turbofan engines  , the annual production capacity of this production cluster is only about 100 units.

    Six hundred units, doesn¡¯t it take six years to produce? For a training equipment that is urgently needed by the troops, the six-year production cycle is really a bit long.

    Therefore, some chiefs have already started to think about whether to suggest setting up similar production clusters in other factories after the inspection in order to expand production capacity and speed up the equipment process of the troops.

    Zhuang Jianye and Liu Chun were not aware of what some of the leaders were thinking. There was no way they could not see it because there were so many people coming this time. The second and most important point was that none of these leaders were given free gifts.  , if all your thoughts were written on your face, I believe you wouldn¡¯t have general stars on your shoulders.

    So it¡¯s normal if they don¡¯t notice it. Of course, even if they notice it, the two of them won¡¯t care. Since they don¡¯t have the means to keep big customers when they visit, then the two of them have been living in vain all these years.

    So after Liu Chun briefly introduced the situation in Workshop No. 12, he glanced at Zhuang Jianye. Zhuang Jianye nodded slightly, and Liu Chun immediately smiled more kindly: "Dear leaders, the machining of aviation heating parts is the most critical in the entire engine manufacturing.  It is a part of the industry, and turbine blades are the key among them. In the past, traditional manufacturing processes only required a month to machine the turbine blades. However, our Tengfei Aviation Power uses the new technologies accumulated in recent years to  We have creatively developed a series of new processing equipment to shorten the machining of engine hot parts, including turbine blades, to about half a month."

      ¡°Half a month?¡±

    Several army leaders asked in surprise.

    Liu Chun nodded: "That's right!"

    As he spoke, Liu Chun pointed to a large piece of equipment not far away: "Commanders, please take a look. This is the nb-600 CNC EDM machine tool that our group just developed and installed at the beginning of this year. It is mainly used for the honeycomb structure of engines and blade sealing.  Machining of key components of aerospace engines such as teeth and sealing reliefs"

    Liu Chun is indeed an old liar. He was told that a CNC EDM machine tool is hard to find in the sky and hard to find on the ground. However, everyone present did not have much objection. Instead, they all opened their eyes wide and listened especially.  serious.

    The reason is very simple. Although there are also applications of electric discharge machining in China, there is no one that can replace traditional machining on such a large scale as Tengfei Aviation Power.

    It¡¯s not that I don¡¯t want to. After all, EDM is a relatively high-precision type in the field of special processing. Under normal circumstances, the accuracy can be controlled at the micron level, and the processing process is not complicated. With CNC technology, it can even complete high-precision and complex shapes.  parts processing.

    This is an alternative processing technology for domestic countries that are limited by foreign trade policies and do not have access to high-precision multi-axis CNC machine tools.

    The problem is that the principle of EDM is not complicated, but CNC technology is a very complex category, especially the special processing used in the field of aviation manufacturing. It is not just a program that can be used as a CNC program for production, but needs to be  After years of accumulation, we have obtained a huge amount of aviation product processing data. After forming a database, we slowly explore and modify it in detail, and then use algorithms to create machine tool operation programs using these data. Only then can we create EDM CNC machine tools that meet actual production conditions.  .

    If not, how come CNC machine tools have become high-end manufacturing? In addition to precision, the key is that these invisible things behind the scenes support the value of such products.

    Other domestic factories have not done well in this regard in the past ten years or so. Anyway, you can buy foreign products at any time, so you have relaxed your self-accumulation in actual production. When the situation changes, your neck will naturally be cut off.

    The Ascendas Group is different. For many years, the professional equipment development team with Peng Chuan as the core has been sorting and collecting the processing data in the actual production of the Ascendas Group. It can be said that every aspect is meticulous. Then, in cooperation with the Aviation Computer Research Institute, through the optimized  The data was compiled into industrial software and CNC programs that conformed to the actual situation of Ascendas Group. After several years of exploration and accumulation, a large number of professional production and processing equipment in the aviation manufacturing field was finally born, which became another major product system of Ascendas Group.

    ?That is, nb series high-end CNC equipment.
