Chapter 1245 Manufacturing technology surpasses F-22

  In fact, even if Zhuang Jianye was not so tactful and directly sprayed these technical leaders, they would not even let out a fart.

  No way, when Zhuang Jianye first introduced the J-8E multi-role fighter, the technical leaders and others, including senior researchers, naturally listened carefully with their ears upright.

After all,    is an important item of the headquarters. They, these technical leaders, understand that it is normal. Anyway, the development of a fighter involves all aspects of supporting.

No matter how strong China Ascendas and Northeast Airlines are capable, it is impossible to eat all of these packages. How can other packages fall into the hands of relevant manufacturers? Because of this, they can make preparations in advance if they understand some details, so that they can take a look. Can you let the old units and old factories participate in it?

   However, talking about the senior researchers and others, it feels wrong. How did it go around and get around the NB-985Plus metal 3D printer?

   Before they could figure out what was going on, Zhuang Jianye's words immediately made them extremely embarrassed.

  Who said that the NB-985Plus metal 3D printer was just a test machine?

  Your China Ascendas did not apply it to the mature model, but you put it on the transition model of the headquarters, OK?

  As a result, I kept saying that which model had not been verified by flight test, and it was not clear whether the performance passed the test.

  I baah~~~

  They are all thousands of old foxes, what do you Zhuang Jianye play in?

  The application of a new technology can only be seen through test flight? Are the previous process demonstrations, metallographic studies, structural tests, and wind tunnel tests all furnishings?

  You, Zhuang Jianye, are so good at deceiving children who don’t know how to do it. But who are they? Leading cadres in the technical field, is it interesting for you to play Zhuang Jianye?

The problem is that they know that Zhuang Jianye is nonsense, but these technical leaders have nothing to say one by one, and they have to pretend to be like this. Even a few artificial technical leaders still whisper to each other subconsciously and cooperate very seriously. The expressions seemed to exchange views on the achievements of China's take-off.

  There is no way. I learned that the NB-985Plus metal 3D printer is just a test machine. The attitude of these people is too obvious.

  If this is a general survey, the key point is not to talk to the military leader. Although he doesn’t speak much along the way, the military leader’s eyes are not blind, and his head is not stupid.

  What attitude do you have before, do the military leaders fail to see it or don’t understand it?

Now China Ascendas has applied the NB-985Plus metal 3D printer to the production of large-scale titanium alloy structural parts in the J-8E multi-purpose fighter, and has achieved very good application results. You technical leaders rushed to hug your thighs and where are your old faces? put?

  If you don’t rush over, the J-8E multi-role fighter is here. Your previous words and attitudes are also very slapstick.

  Flapping, embarrassing; not fluttering, slapping face

  No matter what these technical leaders do, anyway, their old faces are dreadful. What else can they do if they are not embarrassed?

   "President Zhuang, I have a question..."

At this moment, the senior researcher who hadn't spoken for a long time broke the embarrassing atmosphere at the scene, causing a group of technical cadres to cast their puzzled glances over. The meaning is obvious. What do you mean by this, don't you feel embarrassed? ?

To tell the truth, if it is embarrassing, it is no more embarrassing than this senior researcher. I think he personally removed Ascendas Group from the application list in the past, but now people have achieved a high level with NB-996 and NB-985. The revolutionary breakthrough in the manufacture of high-quality aviation forgings has staged the **** drama of Hedong and Hexi for thirty years in the technical field.

  As the decision maker of the year, the senior researcher is no longer as simple as embarrassment, but an old face has long been bombarded with scum.

  If not, how could such a high-profile senior researcher who came to China to take off after seeing NB-996 become so quiet? It's not because you feel embarrassed, you can be as low-key as possible.

However, unlike other technical leaders, senior researchers have participated in the supporting production of various forgings in the two bombs and one star project. The pragmatic approach that is not only the top, not the book, but the pragmatism remains unchanged, even because of Shame and embarrassment can be a little hesitant, but once you feel that something is helpful to the development of the industry and the progress of the country, what embarrassment or embarrassment, this veteran senior researcher really doesn't care.

So he took Zhuang Jianye to introduce the J-8E multi-role fighter, the technical instructions on the NB-985Plus metal 3D printer distributed by the on-site staff, and then turned to a page labeled "Metallographic analysis of a large aviation metal forging" , Looked to Zhuang Jianye: "From the description, the quality of the large metal forgings of the NB-985Plus metal 3D printer is still good, so I asked Mr. Xia Zhuang that the NB-985Plus metal 3D printer is suitable for similar J-8E multi-purpose fighters. What is the maximum manufacturing size of a large-scale structural frame, um...this statement may not be clear, so just give it a number. Can a large-scale titanium alloy structural component with a cross-sectional length of 5.8 meters be produced?"

  As soon as these words came out, everyone present was taken aback, but the next moment, including the military leaders, almost everyone turned their eyes on Zhuang Jianye.

  Hopefully and apprehensively looked at the young central management cadre.

  If this is something outsiders will find it difficult to understand again, isn’t it the increase from 4.2 meters to 5.8 meters, can it be made that important? It makes all the leaders in the army so nervous?

  However, only experienced industry insiders understand what a cross-sectional length of 5.8 meters means.

You know that it is the parameter value of the main structural frame of the American F-22 fighter body. It looks 1.6 meters longer than the 4.2-meter cross-sectional length of the J-8E multi-role fighter. The problem is not to mention too much on the combat aircraft. More than one meter, that is, one centimeter more is subversive.

  What's more, the F-22 fighter, as a typical representative of the next generation of combat aircraft, ~lightnovelpub.net~, has the ability to cruise at supersonic speeds. Therefore, not only the structural strength of the airframe must be particularly strong, but the weight must be reduced as much as possible.

  So it is required that such large structural parts must be integrally formed, so as to ensure the structural strength and reduce the number of similar parts as much as possible, so as to achieve the purpose of structural weight reduction.

  The problem is that the benefits are obvious, but the difficulty of manufacturing is equally scary. The Americans have repeatedly studied this for more than ten years and have not broken through the integrated molding process of such large-size structural parts.

  Finally, such a structure can only be divided into three parts for manufacturing, and then the three parts are combined by linear friction welding to form a unified whole, which is considered to solve this problem.

For this reason, the mood of the military leaders and others is self-evident. If China Ascendas can produce large-scale structural parts with a length of 5.8 meters, it is equivalent to saying that the domestic manufacturing technology of large-scale aviation metal structural parts surpasses the production of F-22. Who can not be nervous after changing the technology?

Of course Zhuang Jianye understood the meaning of this, but he was not nervous. Instead, he said with a smile as usual: "What does the 5.8-meter cross-section length have? Just a few days ago, we produced a cross-section length of The 7.2-meter titanium alloy large-scale structural part, this is not the limit of our ability!"
