Chapter 616

There is no way. In the Gulf War, the highly flexible operation mode of the Tomahawk cruise missile of the US Army, the strange and inexplicable trajectory of action, and the last point damage effect not only made Iraq with integrated air defense system full of teeth, but also shocked the people of insight engaged in national defense research in China.

Because in some ways, the domestic air defense forces are not as advanced as Iraq's. what should we do if we face similar Tomahawk cruise missiles? Is it the only way to watch this thing run wild and be beaten passively?

Because of this, in the case that they are not equipped with similar weapons, good defense has become the top priority of the headquarters. However, this idea is easy to say. There is no clear concept of what cruise missiles are in China, so how to defend them?

At this time, the attack-2 UAV unexpectedly appeared in the confrontation exercise of the red and blue allied forces. The researchers engaged in cruise missile defense saw that it was the target missile prototype they had not found for a long time. So before the end of the exercise, the relevant report had been submitted to the head of the headquarters, and through the head of the headquarters, they reported to the head of the headquarters and higher authorities Report to the decision-making level.

In other times, it doesn't matter how to save money or how to tighten the belt. But when it comes to the fundamental national security, China will spare no effort to make up for this shortcoming. This is true of the two missiles and one satellite in those years, and the same is true of the target-5 Cruise missile.

So after the rapid confirmation of the expert group, the 2 billion large order fell to the head of Tengfei group.

This is also why the wd-30s turbofan engine production cluster of Tengfei aero power company around No.0 assembly workshop is so busy compared with the general production of other aero-engine plants.

Five hundred turbofan engines for target-5 cruise missiles, plus one hundred spare engines, totally 600.

You should know that this is not a bicycle or sewing machine. As soon as the production line is opened and the production line goes offline, the order will be digested in half a year. It's an aeroengine, and it's also a high-performance small turbofan engine. Every part is comparable to the existence of industrial art products. Any process is of cutting-edge level, and the production cycle is calculated by month .

Apart from other things, the technology level of the outermost casing of the whole aero-engine is relatively simple, but such a simple existence also requires the preparation and processing of light alloy materials or composite materials; integral molding; electron beam or laser welding and other processes and manufacturing technology. It takes at least 20 days to take some production steps Take out the well processed casing.

This is simple and difficult. For example, the fan with external duct needs titanium alloy to wrap the honeycomb structure to form a curve shape conducive to air flow.

This involves metallurgy, composite materials, heat treatment, precision processing and other processes and manufacturing technology. Every step is too careless to be fast.

As for the turbine blade of hell level, let alone from the beginning of metal smelting is a very tortuous process.

Because of this, in the eyes of outsiders, the wd-30s turbofan engine production cluster of take-off aviation power is very large, but in the eyes of several directors who are familiar with the industry, it is still a little small. After all, with the ultra long production cycle of turbofan engine, the annual capacity of this production cluster is only about 100.

Six hundred units will be produced for six years. For a training equipment urgently needed by the army, the six-year production cycle is a little longer.

Therefore, some leaders have begun to think about whether they would suggest establishing similar production clusters in other factories after the inspection, so as to expand production capacity and speed up the equipment process of the troops.

Zhuang Jianye and Liu Chun are not aware of the thoughts of some of the leaders. First, there are more people coming this time, and they can't see it. Second, and most importantly, none of these leaders is given in vain. If they write all their thoughts on their faces, Xiangxin will not put stars on their shoulders.

So it's normal not to be aware of it. Of course, even if they are aware of it, they won't care. Since they are waiting for the big customers to visit, if they don't have the means to keep the big customers, the two are really in vain these years.

After a brief introduction of Workshop 12, Liu Chun glanced at Zhuang Jianye. Zhuang Jianye nodded slightly, and Liu Chun immediately laughed more kindly: "Dear leaders, the machining of aviation heating parts is the most critical part in the whole engine manufacturing, and the turbine blade is the key among them. The traditional manufacturing process in the past is the machining of turbine blade It takes a month to work, and we take off aviation power to use the new technology accumulated in recent years to creatively develop a series of new processing equipment, which will shorten the machining of engine hot parts including turbine blades to about half a month. "

"Half a month?"

Several army leaders asked unexpectedly.

Liu Chun nodded: "that's right!"

Liu Chun pointed to a large-scale equipment not far away: "Dear leaders, this is the nb-600 CNC EDM machine developed by our group at the beginning of this year. It is mainly used for machining key parts of aviation engine, such as honeycomb structure of engine, sealing castor teeth of blade, sealing relief plate, etc..."Liu Chun deserves to be an old liar. A CNC EDM machine made him say that it was hard to find in the sky and on the ground. However, the people present did not have much objection. Instead, they opened their eyes and listened very carefully.

The reason is very simple. Although there are applications of EDM in China, none of them replace traditional machining on such a large scale as Tengfei aviation power.

After all, EDM belongs to a kind of high precision in the field of non-traditional machining. Generally, the precision can be controlled at micron level, and the machining process is not complicated. With the help of numerical control technology, it can even complete the machining of parts with high precision and complex shape.

Limited by foreign trade policy, this is a kind of alternative processing technology for domestic enterprises which can not get high-precision multi axis CNC machine tools.

The problem is that the principle of EDM is not complex, but the numerical control technology is a very complex category, especially in the field of aviation manufacturing of special processing, can not be casually do a program can be used as a numerical control program to produce, but it takes years of accumulation, get a huge amount of aviation product processing data, after the formation of a database, and then slowly explore, detailed Fine modification, and then use the algorithm to make the program of machine tool operation in these data, which can make the EDM CNC machine tool in line with the actual production conditions.

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

In the past ten years, other domestic factories have not done well in this aspect. Anyway, they can buy foreign products at any time, so they relax the self accumulation in actual production. When the situation changes, their necks will be cut off naturally.

However, Tengfei group is different. For so many years, the professional equipment development team with Pengchuan as the core has been sorting out and collecting the processing data in the actual production of Tengfei group. It can be said that there are no details in all aspects. Then, it cooperates with the Institute of Aeronautical computer to write the industrial software and numerical control program in line with the actual situation of Tengfei group through the optimized data Finally, a large number of professional production and processing equipment in aviation manufacturing field were born, which became another product system of Tengfei group.

NB series high-end CNC equipment.
