Chapter 1245

In fact, even if Zhuang Jianye is not so euphemistic, he will directly spray on these technical leaders, they will not even let out a fart.

There's no way. When Zhuang Jianye first introduced the j-8e multi-purpose fighter, the technical leaders, including senior researchers, naturally listened attentively.

After all, it's an important item of the headquarters. It's normal for these technical leaders to understand it. Anyway, the development of a fighter involves all aspects of supporting facilities.

No matter how powerful China Tengfei and Northeast Airlines are, they can't eat all of these supporting facilities. How can other supporting facilities fall into the hands of relevant manufacturers? Just because of this, they know some details and can make preparations in advance, so as to see if they can let the old units and factories participate in them.

However, senior researchers and others think it's wrong. How can they get around the nb-985plus Metal 3D printer again?

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

Who said that nb-985plus Metal 3D printer was just a testing machine?

You China take off is not in the mature model application, but you put it, the headquarters focus on the transition model, OK!

As a result, I kept saying that there was no flight test verification for the aircraft, and I didn't know whether the performance was up to standard.

I Pooh~~~

They are all old foxes for thousands of years. What kind of Liaozhai do you play in Zhuang Jianye!

The application of a new technology can only be seen by flight test? Is the previous process demonstration, metallographic study, structural test and wind tunnel test all furnishings?

You Zhuang Jianye said so much. It's OK to cheat the children who don't know what to do, but who are they? Is it interesting for you, Zhuang Jianye, to play with leading cadres in the field of technology?

The problem is that knowing Zhuang Jianye's nonsense, these technical leaders have no choice but to say it one by one. They have to pretend to be so. Even a few artificial technical leaders have subconsciously whispered to each other, with a very serious expression, as if they are exchanging views on the achievements of China's take-off.

I can't help it. I learned that nb-985plus Metal 3D printer is just a testing machine, and their attitude is too obvious.

This is nothing more than general research. The key point is that we don't have to talk to this military leader. Although we don't talk much along the way, the military leader is not blind and stupid.

What's your attitude before? Can't you see it or can't you understand it?

Now China Tengfei has applied the nb-985plus Metal 3D printer to the production of large titanium alloy structural parts in the j-8e multi-purpose fighter, and has achieved very good application results. Where do you technical leaders rush to hold your old face?

If you don't rush in, the j-8e multi-purpose fighter will be here. Your words and attitude are also very offensive.

To throw oneself in disgrace; Don't jump, hit the face.

No matter what these technical leaders do, anyway, the old face is finished. What can we do without embarrassment?

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

At this time, the senior researcher, who had not spoken for a long time, broke the rather awkward atmosphere at the scene, and made a group of technical cadres cast their puzzled eyes on him one after another. That's very obvious. What do you mean, don't you feel embarrassed?

To tell you the truth, if it is embarrassing, there is nothing more embarrassing than this senior researcher. In those days, he personally ranked Tengfei group off the application list. Now, with nb-996 and nb-985, he has achieved a revolutionary breakthrough in the manufacturing of high-quality aviation forgings and staged a hot-blooded drama of Hedong and Hexi in the field of technology for 30 years.

As the decision-maker of that year, the senior researcher is no longer as simple as embarrassment, but an old face has long been blasted into dregs.

If not, how can such high-profile senior researchers become so quiet after seeing nb-996 when they come to China to take off? It's not because of losing face. If you can keep a low profile, try to keep a low profile.

However, unlike other technical leaders, senior researchers have participated in the supporting production of various forgings in the "two bombs and one satellite" project after all. Their pragmatic style, which is not only on the top, not only on books, but only on reality, has not changed. Even if they are hesitant because of shame and embarrassment, once they feel that something contributes to the development of the industry and the progress of the country, what embarrassment and embarrassment, This veteran senior researcher really doesn't care.

When Zhuang Jianye introduced the j-8e multi-purpose fighter, he took the technical description about the nb-985plus Metal 3D printer distributed by the field staff, then turned to the description marked "metallographic analysis of a large aviation metal forging" and looked at Zhuang Jianye: "from the explanation, The quality of large metal forgings of nb-985plus Metal 3D printer is still good, so I asked Mr. Zhuang, what is the maximum manufacturing size of nb-985plus Metal 3D printer for large structure frame like j-8e multi-purpose fighter, er... This statement may not be very clear, let's give a numerical value directly, Can we produce large titanium alloy structural components with a cross-section length of 5.8m? "As soon as the words came out, all the people on the scene were stunned, but the next moment, including the military leaders, almost all of them turned their eyes to Zhuang Jianye.

Looking at this young central management cadre with hope and anxiety.

Once again, it will be difficult for outsiders to understand. Is it not that the increase from 4.2 meters to 5.8 meters is so important? How could it make the military leaders so nervous?

However, only senior industry insiders can understand what a 5.8m cross-section length means.

You know, that's the parameter value of the main structure frame of the F-22 fighter. It's 1.6 meters longer than the 4.2 meters cross-section length of the j-8e multi-purpose fighter. The problem is that it's subversive to say more than one meter, or more than one centimeter, on combat aircraft.

What's more, F-22 fighter, as a typical representative of the next generation of combat aircraft, has the ability of supersonic cruise. Therefore, the structural strength of F-22 fighter should not only be particularly strong, but also the weight should 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, so as to achieve the purpose of structural weight reduction.

The problem is that the advantages are obvious, but the difficulty of manufacturing is also frightening. Americans have studied this for more than ten years, but they have not broken through the integrated molding process of such large-size structural parts.

Finally, the structure can only be divided into three parts for manufacturing, and then the use of linear friction welding will combine the three parts to form a unified whole, which can solve this problem.

For this reason, the mood of the military leaders and others is self-evident. If China takes off can produce 5.8m long large structural parts, it means that the manufacturing technology of large aviation metal structural parts in China surpasses that of F-22. Who can not be nervous?

Of course, Zhuang Jianye understood the meaning, but he was not nervous. Instead, he said with a smile as usual: "what's the difference in the cross section length of 5.8 meters? Just a few days ago, we produced a large titanium alloy structure with a cross-section length of 7.2 meters, which is not up to the limit of our ability! "
