Take Off My Aviation Era

  Chapter 1238 Subversion

"There are also five such workshops in the park, which are equipped with a total of 80 NB-996Plus metal 3D printers. If the current six workshops are fully engaged in production, one WD-18 highly integrated small vortex can be rolled off the line in an average of four and a half minutes. Jet engine.

According to our overall design of DZB-2000T, the service life of WD-18 is only 3 hours, but thanks to the excellent process capability of NB-996Plus metal 3D printer, in fact, the actual use of integrated processing of WD-18 The life span has reached 12 hours, which is 4 times our theoretical life span.

Therefore, domestic and foreign similar companies generally do not exceed 3 minutes in the test time of such disposable turbojet engines, but our China Ascendas has increased the factory test to 5 minutes. This also proves from another perspective that the process we use is reliable. Sex..."

  Just when senior researchers and others were surprised by the production situation on site, Zhuang Jianye slowly spoke and introduced the production situation of the WD-18 small turbojet engine.

  It's okay that the senior researchers and others didn't listen. When I heard it, my heart shook, and I almost didn't panic my chin.

No way, I really did not expect the service life of WD-18 to reach double digits. It is good to know that this kind of disposable turbojet equipped with missiles can have a service life of several hours. It is also a waste to blow up into a pile of scrap iron together, and the service life is too long.

  However, short and short, the manufacturing process of this type of small turbojet engine is not simple at all. At least during the service life, the stability of this type of small turbojet must be 100% reliable.

Because of this, such small engines can be simplified on some thermal components such as turbine blades and combustion chambers, but they have to rely on forgings as a whole to support them. It can even be said that such small turbojets are supported by forgings. of.

  In this way, the expected stability can be achieved in just a few hours of use cycle.

  However, the WD-18 at this moment actually exceeded the service life of a few hours of traditional products, reaching an unprecedented 12 hours.

  What does this mean?

  For such a length of time as the military leader, with enough fuel, it can increase the range of cruise missiles by several times. It is an absolute combat power multiplier.

  In the eyes of senior researchers and many other technical personnel, it is not only as simple as improving combat effectiveness, but completely subverting tradition.

  Because Zhuang Jianye made it very clear that the reason why WD-18 adds a high integration in front of the small turbojet engine is mainly because 78.6% of WD-18 is produced by NB-996Plus metal 3D printer.

  In other words, except for some supporting parts such as screws, gears or bearings, almost all the important parts of WD-18 are integrally formed by the NB-996Plus metal 3D printer.

  As a result, WD-18 components have been reduced from the traditional more than 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 stronger than the traditional manufacturing process.

  However, this is not the focus of the most attention of senior researchers and others. What they care about is the fact that the NB-996Plus metal 3D printer subverts their three views.

  There is no way, a WD-18 in a corner of the workshop is undergoing a random inspection test, and it needs a full life test 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, and there is no sign of scrapping.

  Achieving 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 not worse than that of high-precision forgings, or even slightly better in a sense.

This means that the workshop, equipment, physical objects, and tests are all at a glance. Otherwise, even if the dead are said to be 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. Including senior researchers, almost all domestic experts and scholars in related fields have accepted the Americans’ conclusions.

   But now, the Americans’ conclusions are refreshing their three views time and time again in the busy production of the NB-996Plus metal 3D printer.

  The Americans are wrong?

  China's take-off process has reached this level?

  Is it possible to use metal additive technology to make metal parts that are as good as forgings in China?

  ……

  Countless questions raged in the minds of senior researchers and others, so that at a certain point in time they felt that they were dreaming? Or is it in a different space?

  Otherwise, how could there be an unreal feeling!

  It’s no wonder that senior researchers have such a mentality. It is that the traditional forging manufacturing process is too complicated and requires nearly 20 process categories such as forging, machining, forging, and welding to be completed.

  Each process category is the pinnacle of technology in the field of industrial manufacturing in the world today.

  Don’t talk about 10,000-ton forging machines, just say that in terms of machining, five-axis or seven-axis machine tools are generally used for precision machining. For long lengths, it is necessary to process several tons of metal blanks to an ultra-precision state of only hundreds of kilograms.

Secondly, the consumption is high. The most important thing is that the equipment cannot be stopped once it is started, unless the processing of the entire part is finished. There is no way. As a precision part in aerospace, the precision required is very high. The tool of the equipment is slightly filed because of the pause. So a few threads, hundreds of thousands or even millions of parts worth completely scrapped.

  Because of this, this type of machining equipment must not only have high precision, but also have extremely high stability, and the most important thing is long standby.

  Except for a few developed countries such as the United States and France, which can produce it~www.readwn.com~, there is no substitute in the world.

And this is where the developed countries have a firm grasp of the aerospace manufacturing industry and have the confidence to capture excess profits in the world. Even if developing countries are given half a century of time to catch up, they may not be able to catch up. Technology has already broken through to the new ladder, so that you can't see the taillights of your car, and you are so desperate that you only call mother.

  Of course, this is just an ideal state. In reality, developing countries may not wait to catch up, and developed countries will directly stifle your expectations with various names.

  Let you have no time to give birth to a desperate heart, just be obedient!

However, all of this seems to be directly broken by the NB-996Plus metal 3D printer. What 10,000 tons of forging equipment, what five-axis seven-axis machine tool, what high precision, high stability, and long standby time, let's go all the way. In the past, it was directly integrated.

  This is like marrying a daughter-in-law. The traditional custom of three-media six-employment, eight-carrying sedan chair and flowing water banquet can drive people crazy; the new avant-garde concept is to get a marriage certificate and go directly to the bridal chamber.

  This kind of shock is shocking enough for young people, let alone senior researchers and old technical workers, where can we go without subversion?
