Chapter 1240

"Mr. Zhuang, don't be joking!"

"Specialized in additive manufacturing equipment for large structural parts? How is the quality of production compared with that of imported forgings? "

"Are there any finished products for sale? My old company was short of such equipment! "

……

As soon as Zhuang Jianye's words came out, the technical leaders of the research group around him would shine their eyes one by one, and instantly incarnate themselves as small partners to help, asking incessantly.

Not to mention them, the senior researcher, who was full of embarrassment and tangle not far away, trembled inexplicably when he heard that China Tengfei had nb-985plus Metal 3D printer, a special production equipment for large structural parts.

If China's take-off even breaks through the large-scale metal structures in the aerospace field, it will not be as simple as subversion and revolution, but directly create an era.

At that time, the traditional forging technology barriers and industrial chain that developed countries are proud of will be crushed into powder by China's take-off. Not to mention, it will also be burned directly into ash, and then thoroughly raised to the historical garbage heap.

But

Just as the senior researcher was wandering between astonishment and disbelief, Zhuang Jianye's next sentence was to let the senior researcher completely put down his heart: "leaders, leaders, don't worry, listen to me. The current situation is like this. Our nb-985plus Metal 3D printer has only made two prototypes for testing, and the relevant progress is only in progress More than half, but so far, the performance is very good. If you leaders need, you may as well help us to invest and sponsor in related fields, and work together to carry on this project.... "

What Zhuang Jianye said is that his face is not red and his heart is not beating. He has brought the three words "shameless" into full play. What is the introduction of new technological achievements? He is pulling his head into the pit with a gimmick.

Who are the people present? Are they not ordinary technical cadres? Those are all technical leaders. Are there any simple ones that can hang the word "leader"?

No!

Therefore, after listening to Zhuang Jianye's words, the excited expressions of these technical leaders disappeared instantly, and the eyes looking at Zhuang Jianye also became strange.

There are physical objects, applications, products, and testing things, so they can go home with ease. There is nothing, full screen concept, gimmicks, and a mouth. The leaders of this group really want to discuss with Zhuang Jianye what it means not to see rabbits and not to cast eagles.

As a result, the technical leaders who were in the front gradually slowed down, and some selfish desires became more and more inexplicable. It seemed that they attached great importance to Zhuang Jianye's proposal, but in fact, they used this obscure way to tell Zhuang Jianye not to cheat. Let's make something affordable, such as your nb-996plus Metal 3D printer What is the capacity?

However, what makes these technical leaders speechless is that Zhuang Jianye's face seems to be even more invincible than the rumor, and their hint is almost out of the vernacular, but Zhuang Jianye, like the blind and deaf, can't see or hear at all.

That's all. The problem is that the goods lead the people to leave the workshop where they are.

Don't go. Just now, everyone was so urgent, and it was also a rare technological achievement. If you don't go to see it, you will not be able to say it, but you will also face it. But what's the use of going? It's just two test machines. It's unknown whether Chengdu can be built. After all, the manufacturing of large-scale metal structural parts in the aerospace field is a worldwide problem.

The required forging, precision forging and machining process is almost the pinnacle of human technology in this field.

Among other things, the main structural beam of the wing of the U.S. B-2 bomber is 16.8 meters long and made of high-strength titanium alloy. It is mainly used to support the wing skin and internal fuel tank.

Therefore, it is required that the 16.8m main beam should be formed at one time without any damage, welding and cracking in the middle, so as to meet the design requirements.

For this reason, the United States developed a complete set of forging production system around the main structural beam in the 1980s.

On this basis, the United States applied this system to the production of Boeing series airliners, which increased the structural strength of the aircraft wings by several times. As a result, it crushed its competitor Airbus in technology, forcing Airbus to reduce its price and keep the market while biting its teeth to make similar research and development.

However, over the years, Europe has made little progress in this regard. It has to spend a lot of money to buy patented technology from the United States to solve its urgent need.

Thus, it can be seen how difficult it is to manufacture such large metal structural parts, but once the breakthrough is made, the profits are also amazing.

Because of this, these technical leaders, even the most confident ones, will have to wait ten or eight years for their views on China's soaring nb-985plus Metal 3D printer to finally mature. After all, it is a brand-new technical route. If there are tens of thousands of optical experiments, it is still called experiment?

As for the pessimists, they just take Zhuang Jianye's words as a hoax. It's just a left ear coming in and a right ear coming out. They really don't want to listen to a word carefully.However, while introducing the investment situation of nb-985plus Metal 3D printer project, Zhuang Jianye stepped into an open workshop and was ready to take a shortcut to the next workshop. Suddenly, a deep question came from the silent research group: "Xiaozhuang, what kind of plane is this?"

As soon as the words came out, the people followed their reputation. Then they found that the military leader who had been following them all the time was standing next to an aircraft covered with cloth. He was pointing at the aircraft and looking at the stopped Zhuang Jianye: "this aircraft is a new model that you have not seen before. It's your own?"

Hearing the speech, Zhuang Jianye immediately replied with a smile: "it's not a new model, or the latest improved model of J-8 jointly developed by us and Northeast Airlines Group."

"Do you mean that the j-8e multi-purpose combat model approved by Northeast Airlines Group has gone offline?" At this time, the head of the headquarters stood out from the crowd and looked at Zhuang Jianye in disbelief.

Zhuang Jianye nodded: "two days ago, the flight test verification plane just came off the production line. It's going to be transported to Northeast Airlines Group by the special cargo plane tomorrow and the day after tomorrow, and then the flight test ceremony will be held there. Er It's reasonable to say that Northeast Airlines should deliver the report. Chief, you can't be... "

Zhuang Jianye didn't finish his words, but the meaning is very obvious, that is, this matter is all handled by Northeast Airlines. Their China take-off is a supporting system. You can go to Northeast Airlines if you want.

Before the military leaders left the capital, there was indeed a report from Northeast Airlines. However, they were anxious to come to China for research, so they didn't have time to read it.

However, this is not the point. What the military leaders care about now is how the first domestic multi-purpose fighter plane is. Without waiting for Zhuang Jianye to explain, people will uncover the veil.

In an instant, a group of people, including the military leaders, were completely amazed by the plane in front of them!
