Take Off My Aviation Era

No way, during the Gulf War, the US Army’s "Tomahawk" cruise missiles’ highly flexible combat methods, strange and inexplicable trajectories, and final acupuncture-style damage effects not only fought Iraq, which has an integrated air defense system, to find teeth. It also shocked people of insight engaged in national defense research.

Because in some respects, domestic air defense forces are still not as advanced as Iraq, what should we do if we face similar "Tomahawk" cruise missiles? Do you have to watch this thing run wild and get beaten passively?

Because of this, in the absence of 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 cruise missiles in China, so what? To defend?

At this time, the Attack-2 UAV accidentally appeared during the confrontation exercise of the Red and Blue coalition forces. Those researchers engaged in cruise missile defense saw that this is the prototype of the target bomb they haven’t found for a long time. So before the end of the exercise, the relevant report has been submitted to the head of the headquarters, and the head of the headquarters will report to the headquarters and higher decision-making levels.

At other times, it doesn’t matter how to save money or how to tighten the waistband, but when it comes to the fundamental security of the country, China will spare no effort to make up for this shortcoming. That was the case with the two bombs and one satellite that year. Target-Type 5 cruise. The same applies to missile-specific targets.

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

This is why, compared to the general production of other aero engine plants, Ascendas Aviation Power's wd-30s turbofan engine production cluster around the No. 0 assembly workshop is so busy.

Five hundred sets of turbofan engines for supporting target-type 5 cruise missiles, plus one hundred spare engines, make a total of six hundred sets.

You must know that this is not a bicycle or a sewing machine. Once the production line is turned on, the order can be digested in half a year. It is an aero engine, and it is also a high-performance small turbofan engine. The components are comparable to the existence of industrial art, any craftsmanship is of cutting-edge level, and the production cycle is calculated on a monthly basis.

Among other things, the outermost casing of the entire aeroengine is considered to have a relatively simple technical level among all components, but it is such a simple existence that 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 blessings, after a series of production steps, it takes at least about 20 days to come up with a well-processed receiver.

This is simple and difficult, such as an external ducted fan that requires a honeycomb structure wrapped in titanium alloy to form a curved shape that is conducive to air flow.

This involves metallurgy, composite materials, heat treatment, precision machining, and other processes and manufacturing technologies. Every step is sloppy, and you can't get up soon.

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, in the eyes of outsiders, the production cluster of Ascendas Aerodynamics' wd-30s turbofan engines is very large, but in the eyes of several leaders, it is still a bit small. After all, the super-long production cycle of turbofan engines , The annual production capacity of this production cluster is limited to about 100 units.

Isn’t 600 units going to be produced for six years? For a piece of training equipment urgently needed by the army, the six-year production cycle is a bit longer.

Therefore, some chiefs have already begun to figure out whether after the inspection is over, should they recommend the establishment of similar production clusters in other factories in order to expand production capacity and accelerate the equipment process of the troops.

Zhuang Jianye and Liu Chun were not aware of the thoughts and thoughts of some of the chiefs. There were more people who came this time and couldn't come by. The second and most important point is that none of these chiefs was given for nothing. , If you write all your thoughts on your face, I believe you won’t have a star on your shoulders.

So it's normal if you don't notice it. Of course, even if you notice the two, you don't care about it. Since you are waiting for a big customer to visit, if you don't have the means to keep the big customer, the two of them have really been for nothing these years.

So after Liu Chun briefly introduced the situation of Workshop No. 12, he glanced at Zhuang Jianye, Zhuang Jianye nodded slightly, and Liu Chun immediately smiled more kindly: "Dear chiefs, machining of aviation heating components is the most important part of the entire engine manufacturing. Turbine blades are one of the key points, and the traditional manufacturing process in the past requires only one month for the machining of turbine blades. We take advantage of the new technologies accumulated in recent years by Ascendas Aerodynamics. 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 heads of troops asked a little unexpectedly.

Liu Chun nodded: "That's right!"

Speaking of Liu Chun pointed to a large-scale equipment not far away: "Dear heads, please take a look. This is the nb-600 CNC EDM machine developed by our group at the beginning of this year. It is mainly used for the honeycomb structure of the engine and the sealing of the blades. Machining of key components of aero-engines, such as gears and sealed toppan..."

Liu Chun is worthy of being an old fool. A CNC EDM machine made him say that it is hard to find in the sky and hard to find on the ground. However, everyone present did not have much objection. On the contrary, they opened their eyes and listened exceptionally. serious.

The reason is simple. Although there are also applications of EDM in China, there is none that replaces traditional machining on such a large scale as Tengfei Aerospace.

It’s not that I don’t want to. After all, EDM is a kind of high precision in the field of special machining. Normally, the precision can be controlled at the micron level, and the machining process is not complicated. It can even be completed with high precision and complex shapes with CNC technology. Parts processing.

This is an alternative processing technology for projects that are restricted by foreign trade policies and cannot obtain high-precision multi-axis CNC machine tools.

The problem is that the principle of EDM is not complicated~www.readwn.com~, but CNC technology is a very complicated category, especially the special machining applied in the field of aviation manufacturing. It is not just a program that can be used as a CNC program. To produce, it takes years of accumulation to obtain huge aerospace product processing data, form a database, and then slowly explore and modify it in detail, and then use algorithms to make a program for machine tool operation in order to make a program that meets actual production. Condition of the EDM CNC machine.

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.

Other domestic factories have not done well in this aspect in the past ten years. Anyway, they can buy foreign products at any time, which relaxes the self-accumulation in actual production. When the situation changes, the neck is naturally cut off.

The Ascendas Group is different. For so many years, the professional equipment research and development team with Pengchuan as the core has been collating and collecting the processing data in the actual production of Ascendas Group. It can be said that everything is fine. Data compilation conforms to the actual situation of Ascendas Group's industrial software and numerical control programs. After years of exploration and accumulation, a large number of professional production and processing equipment in the aviation manufacturing field has finally been born, which has become another major product system of Ascendas Group.

Namely nb series high-end CNC equipment.
