- "There are five more such workshops in the park, equipped with a total of 80 nb-996plus metal 3D printers. If the six workshops are currently in full production, one wd-18 highly integrated small vortex printer can be offline in an average of four and a half minutes. Jet engine.
According to our overall design of the dzb-2000t, the service life of the wd-18 is only 3 hours. However, thanks to the excellent process capabilities of the nb-996plus metal 3D printer, in fact, the integrated processing of the wd-18 is actually used The lifespan reaches 12 hours, which is 4 times our theoretical lifespan.
Therefore, when similar companies at home and abroad generally test such disposable turbojet engines for no more than 3 minutes, China Tengfei has increased the factory test to 5 minutes, which also proves from another perspective that the reliability of the process we use is sex¡¡"
Just when the senior researcher and others were surprised by the production conditions at the site, Zhuang Jianye slowly opened his mouth and introduced the production situation of the wd-18 small turbojet engine.
It turned out that it was a good thing that the senior researcher and others did not listen. When I heard this, my heart skipped a beat and my jaw almost dropped.
No way, I really didn't expect that the service life of wd-18 would reach double digits. It is good to know that this kind of disposable turbojet equipped on missiles can have a service life of several hours. After all, it is to be used with missiles. Exploded together into a pile of scrap metal, the service life is too long and it is also a waste.
However, the shortcoming is that the manufacturing process of this type of small turbojet engine is not simple at all. At least during its service life, the stability of this type of small turbojet must be 100% reliable.
Because of this, this type of small engine can be simplified in some thermal components such as turbine blades and combustion chambers, but it must rely on forgings as a whole for support. It can even be said that this type of small turbojet is supported by forgings. of.
Only in this way can the expected stability be achieved in just a few hours of use.
However, at this moment, the wd-18 actually exceeds the service life of several hours of traditional products, reaching an unprecedented 12 hours.
What does this mean?
With such a length of time and enough fuel, the range of the cruise missile can be increased several times by the military leaders, which is an absolute combat power multiplier.
But in the eyes of senior researchers and other technicians, it is not just about improving combat effectiveness, but a complete subversion of tradition.
Because Zhuang Jianye made it very clear that the reason why WD-18 adds a high level of integration in front of the small turbojet engine is mainly because 78.6% of WD-18 is produced by nb-996plus metal 3D printer.
That is to say, except for some supporting parts such as screws, gears or bearings, almost all important parts of wd-18 are integrally formed by nb-996plus metal 3D printer.
As a result, the number of wd-18 parts has been reduced from the traditional 3,200 to 64, and the production cycle has been shortened from the traditional 28 days to two and a half hours.
¡°Whether it is maintainability or production cost, I don¡¯t know how many times it is better than the traditional manufacturing process.
However, this is not the focus that senior researchers and others are most concerned about. The key thing they care about is the fact that the nb-996plus metal 3D printer has subverted their three views.
There is no way. In the corner of the workshop, a wd-18 is undergoing random inspection tests. It needs to be tested throughout its life in order to evaluate the quality of this batch of products.
Now this wd-18 has been running for more than 8 hours, and the value on the monitoring screen is still stable, without any signs of scrapping.
Reaching this level is enough to show that the manufacturing process of wd-18 is quite excellent.
In other words, the quality of integrated molded parts made by the nb-996plus metal 3D printer is no worse than high-precision forgings, and in a certain sense, it is even slightly better.
This means that the workshop, equipment, physical objects, and tests are all at a glance. Otherwise, even if the dead are brought alive, senior researchers and others will not believe that additive manufacturing can actually produce high-quality metals that are comparable to traditional forgings. Parts.
The Americans have directly put an end to the prospects of this technology. Almost domestic experts and scholars in related fields, including senior researchers, have accepted the Americans¡¯ conclusion.
But now, Americans¡¯ conclusions are refreshing their views again and again in the busy production of nb-996plus metal 3D printer.
Are Americans wrong?
Has China¡¯s take-off technology reached this level?
Is it possible in China to use metal additive technology to make metal parts that are as good as forgings?
¡¡
Countless questions are surging in the minds of senior researchers and others, so much so that at a certain point in time they feel like they are dreaming? Or are you in a different space?
?Otherwise, why would there be an unreal feeling!
It¡¯s no wonder that senior researchers have such a mentality. The traditional forging manufacturing process is really too complicated and requires the cooperation of nearly 20 process categories such as forging, machining, forging, and welding to finally complete it.
??Each of these process categories is the technological pinnacle of industrial manufacturing in the world today.
???????????????????????????????????????????????????????????????????????????????????????????????????????????????? did not talk about machining? Five-axis or seven-axis machine tools are generally used for precision machining. For a long time, metal blanks weighing several tons need to be processed to an ultra-precise state of only a few hundred kilograms.
Secondly, the consumption is huge. The most important thing is that once the equipment is started, it cannot be stopped until the entire component is processed. There is no way. As precision parts in aerospace, the required precision is very high. The tool of the equipment is slightly filed due to the stop. With just a few wires, components worth hundreds of thousands or even millions would be completely scrapped.
Because of this, this type of machining equipment must not only have high precision, but also have extremely high stability, and most importantly, long standby time.
Except for a few developed countries such as the United States and France that can produce it, there is no substitute in the world.
And this is also the basis for developed countries to firmly grasp the aerospace manufacturing industry and seize excess profits around the world. Even if developing countries are given half a century to catch up, they may not be able to catch up. Even if they catch up, other developed countries will not be able to catch up. Technology has long since broken through to a new level, so that you can¡¯t even see the taillights of your car, and you¡¯re so desperate that you can only call mom.
Of course, this is just an ideal state. In reality, before developing countries can catch up, developed countries will use various names to directly kill your expectations.
????????????????????????????????????????????????¡
However, all this seems to have been directly broken by the nb-996plus metal 3D printer. Thousand-ton forging equipment, five-axis and seven-axis machine tools, high-precision, high-stability, and ultra-long standby are all put aside. I have surpassed them all. In the past, it was directly integrated.
This is like marrying a daughter-in-law. The traditional custom of three matchmakers and six betrothals, eight large sedans, and a flowing banquet can drive people crazy; the new and avant-garde concept is to get a marriage certificate and go directly to the bridal chamber.
This kind of impact is shocking enough to young people, let alone senior researchers and other old technical workers. Where can they go without subversion?
