In fact, even if Zhuang Jianye was not so tactful and directly complained to these technical leaders, they would still not even let out a fart.
No way, when Zhuang Jianye first introduced the J-8e multi-purpose fighter, the technical leaders, including senior researchers, naturally listened carefully.
After all, it is an important project of the headquarters. It is normal for these technical leaders to understand it. In any case, the development of a fighter aircraft involves all aspects of supporting facilities.
No matter how powerful China Ascendas and Northeast Airlines are, they cannot eat up all these packages. How can other packages fall into the hands of relevant manufacturers? Because of this, they understand some details and can make preparations in advance so that they can take a look. Can old units and factories be involved?
However, as they were talking, the senior researcher and others felt that something was wrong. Why did it get around to the nb-985plus metal 3D printer?
But before they could figure out what was going on, Zhuang Jianye's words immediately made them feel extremely embarrassed.
Who said before that the nb-985plus metal 3D printer is just a test machine?
??You China Tengfei has not applied it on mature models, but you have put it on the transitional models that are the focus of the headquarters, okay?
The result is that they keep saying that the model has not been tested and verified, and it is not clear whether the performance is acceptable.
They are all thousand-year-old foxes, what are you, Zhuang Jianye, doing?
??The application of a new technology can only be judged through test flights? Are the previous process demonstrations, metallographic studies, structural tests, and wind tunnel tests all just for show?
"You Zhuang Jianye said so much that it's okay to deceive uninformed children, but who are they?" As a leading cadre in the technical field, is it interesting for you, Zhuang Jianye, to do this?
The problem is that even though they know that Zhuang Jianye is talking nonsense, these technical leaders have no choice but to say it, and they have to pretend that it is really the case. Some of the pretentious technical leaders even subconsciously whisper to each other and cooperate with the very serious words. Their expressions seemed to be exchanging views on the achievements of China's take-off.
There is no way, I learned before that the nb-985plus metal 3D printer is just a test machine, and the arrogant attitude of these people is too obvious.
??????????????? If this is just a general survey, the key is not to have this big leader in the army with you. Although he didn¡¯t talk much along the way, the big leader in the people¡¯s army is not blind, and he is not stupid.
??????Did the military leaders not see or understand your previous attitude?
Now China Tengfei 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 jet, and has achieved very good application results. You technical leaders have jumped in and hugged your thighs, where are you going with this old face? put?
If you don¡¯t pounce, the J-8e multi-role fighter will be right here. Your previous words and attitude are also very disappointing.
If you pounce, you will be embarrassed; if you don¡¯t pounce, you will be slapped in the face.
No matter what these technical leaders do, they are already dead. What else can they do without embarrassment?
"Mr. Zhuang, I have a question"
At this moment, the senior researcher who had not spoken for a long time broke the awkward atmosphere at the scene, causing a group of technical cadres to cast doubtful glances over. The meaning is obvious, what do you mean by this, don't you feel embarrassed? ?
To be honest, if you want to talk about embarrassment, there is nothing more embarrassing than this senior researcher. I think back then he personally removed Ascendas Group from the application list, but now he has achieved success in high school with nb-996 and nb-985. The revolutionary breakthrough in the manufacturing of high-quality aviation forgings has staged a passionate drama of thirty years in Hedong and thirty years in Hexi in the technical field.
As the decision-maker back then, the senior researcher was no longer just embarrassed, but an old face that had been turned into scum long ago.
If not, why did such a high-profile senior researcher when he came to China become so quiet after seeing nb-996? It¡¯s not just because I feel ashamed, I should keep a low profile as much as possible.
However, unlike other technical leaders, the senior researcher has participated in the production of various forgings for the two-bomb and one-star projects. His pragmatic style of not only being superior, not book-oriented, but just pragmatic has not changed, even because There will be some hesitation when it comes to humiliation and embarrassment, but once he feels that something will contribute to the development of the industry and the progress of the country, this veteran senior researcher really doesn't care about embarrassment and humiliation.
So he took the technical description of the nb-985plus metal 3D printer distributed by the on-site staff when Zhuang Jianye introduced the J-8e multi-purpose fighter, and then turned to a page marked "A certain large aviation metal forging.""Phase analysis" explanation, he looked at Zhuang Jianye: "From the description, the quality of large metal forgings made by nb-985plus metal 3D printer is quite good, so I asked Mr. Zhuang, nb-985plus metal 3D printer is good for similar J- What is the maximum manufacturing size of a large structural frame like the 8e multi-purpose fighter jet? Well this statement may not be clear, so just give me a numerical value. Is it possible to produce large titanium alloy structural components with a cross-sectional length of 5.8 meters? "
As soon as these words came out, everyone present was stunned for a moment, but the next moment, almost everyone, including the military leaders, turned their attention to Zhuang Jianye.
He looked at the young central management cadre with hope and apprehension.
? ? If outsiders would find this a bit difficult to understand, isn¡¯t it just an increase from 4.2 meters to 5.8 meters? Is it so important whether it can be done? It actually makes the top leaders in the army so nervous?
However, only senior industry insiders understand what the cross-sectional length of 5.8 meters means.
You must know that those are the parameter values ??of the main structural frame of the American F-22 fighter body. It seems to be 1.6 meters longer than the 4.2-meter cross-sectional length of the J-8e multi-purpose fighter. The problem is that on a combat aircraft, let alone the extra More than one meter, even one centimeter more, is subversive.
What¡¯s more, as a typical representative of the next generation of combat aircraft, the F-22 fighter jet has the ability to cruise at supersonic speeds. Therefore, the structural strength of the aircraft body must not only be extremely strong, but also the weight must be reduced as much as possible.
Therefore, it is required that such large structural parts must be integrated, so as to ensure the structural strength and reduce the number of similar parts as much as possible, thereby achieving the purpose of reducing structural weight.
The problem is that the benefits of this are obvious, but the difficulty of manufacturing is also scary. Americans have been studying this repeatedly for more than ten years, but they have not yet broken through the integrated molding process of such large-size structural parts.
In the end, this problem can only be solved by splitting such a structural part into three parts for manufacturing, and then using linear friction welding to combine the three parts to form a unified whole.
For this reason, the mood of the military leaders and others is self-explanatory. If China Takeoff can produce large structural parts of 5.8 meters long, it means that the domestic manufacturing technology of large aviation metal structural parts has surpassed the production of F-22 Technology, who wouldn¡¯t be nervous if it changed?
Of course Zhuang Jianye understood the meaning of this, but he was not nervous, but said with a smile as usual: "What does the cross-sectional length of 5.8 meters mean? Just a few days ago, we produced a cross-sectional length of A 7.2-meter large titanium alloy structural part, that¡¯s it, it¡¯s not at the limit of our capabilities!¡±
