Take Off My Aviation Era

　　Listening to the shot peening process, Lin Guanghua and the others were at a loss. They were obviously very unfamiliar with it, but Shi Jun looked as though he was no stranger.

　　 Qiao Chenyu smiled: "Xiao Shi, do you know shot peening takes shape?"

　　 "I read some foreign language materials in school, and they mentioned it." Shi Jun did not hide it, and responded.

"Oh? Tell me about it." Qiao Chenyu was also a little curious. Shi Jun nodded and continued: "The so-called shot peening, as the name implies, is a process of cold working parts with small metal shot peening. Our main application in the aviation industry is to process ribbed integral panels or thick skins, which are what we often call wing panels and complex skin parts.

　　 Everyone knows this kind of parts. Because of the large outer size, the thickness of the plate and the strong layer, the inner structure is complicated, which brings many difficulties to the forming work. At present, we are using the Soviet КГЛ-2 skin rolling machine to process such parts by rolling. "

After speaking for a while, he glanced at the КГЛ-2 skin bending machine that was still running in the hands of the workers not far from the workshop. It ran slowly and awkwardly, making a caracalla sound, and Shi Jun sighed. Continued: "It's just that the roll bending machine using the three-point bending principle to form single-curvature wing, tail and integral skin panel parts is not an ideal method.

Nothing else because this method has low forming accuracy and difficult quality control. It not only requires skilled workers to perform precise operations during overall processing, but also requires sheet metal workers to perform a large number of manual corrections after forming. However, the shot peening process described by Director Qiao can Not to mention the shortcomings of the roll bending machine, it can also strengthen and eliminate the strength and stress of the overall wall panel. This is the inherent advantage of the shot peening process. "

　　 "Yes, Koishi is right."

　　 Qiao Chenyu glanced at Shi Jun approvingly, and felt that he really found a treasure, strong ability, willingness to attentive, broad knowledge and understanding of business management. Such compound talents are simply a role model for young workers in the factory.

In contrast, Zhuang Jianye, who is favored by the chief engineer, is much worse. Although he quietly helped the two branch factories to make technical renovations, Qiao Chenyu still didn’t think he was better than the others. We must know that many of the new college students who have entered the factory have already published professional papers, and the worst have also written research on technological improvement in authoritative journals.

　　 Lin Guanghua is considered the worst among his group of people, but he also has a paper and a technical article in hand. What does Zhuang Jianye have? Nothing, oh, that's not right, Zhuang Jianye got the daughter of Minister Ning's house, and it was considered capable.

But in the eyes of Qiao Chenyu, who values ​​scientific research results, this kind of skill is really nothing. Therefore, during the meeting in Beijing, the chief engineer asked him to form a research and development team for trial production models. Qiao Chenyu took the published results as a rigid indicator, and Zhuang Jianye was naturally excluded. outer.

Of course, these are all digressions. Now, as long as you get the prototype model and work hard, Qiao Chenyu doesn’t believe it. Where can the gang of his lads go? What about the old man with an organization minister? Skills are the long-term way.

The thoughts in my head flashed by, and the smile became more cordial and kind: "The shot peening process is still a new thing in our country. It has just started, but it has been popularized in developed countries such as Europe and America, especially Boeing, Mai For such a powerful aviation company, a single wing panel has to be 20 to 30 meters long. How big a roll bending machine can be processed, not to mention the inherent defects of the roll bending machine will make such parts The defect affects flight safety.

Therefore, they have long applied the shot peening process to the formation of wings, tails and skins of large airplanes. As far as I know, American B-52 bombers, Boeing 707, Boeing 747, DC-10 and other aircraft are all used. Not only that, but the new generation of combat aircraft in Europe and the United States also used shot peening. It can be said that this technology has become the core technology of the aviation industry and the first choice for the manufacture of wings and tails. "

Lin Guanghua and others are quite stupid. I didn’t expect this technology to be the core technology of European and American wing and tail manufacturing. Not to mention them, even Shi Jun, who is very knowledgeable, was a little surprised. He knew that shot blasting was very important, but But I didn't expect it to be so important.

So the next moment a fiery heart jumped, Qiao Chenyu said so, and he also dragged them to the first assembly workshop known as "Bronze Head", that is to say, they will participate in this project, which is regarded by European and American aviation powers. The core research.

Not only him, but Lin Guanghua and others realized this, and their faces flushed red. Regardless of their selfishness, the enthusiasm of aviation to serve the country has never been obliterated. If they can catch up with the world's advanced technology through their hands, it will be their life. Of glory.

Qiao Chenyu didn't say anything, but quietly looked at the passionate appearance of the young people in front of him, as if he had seen his lofty ambition when he first entered the factory, nodded with satisfaction, and spread the technical information in his hand on the long table. , Greeted: "Let's start now."

　　 There is no magnificent slogan, and no solemn ceremony. Starting with a simple sentence, everyone will understand that they will shoulder the burden of catching up from this moment.

　　 One by one, he immediately invested 120% of his enthusiasm. UU read www.uukānshu.com and plunged into it.

Soon three days passed. Under the leadership of Qiao Chenyu, Shi Jun and others reorganized the data and analyzed the data in a more detailed manner. Everything seemed to be tense and smooth. The new spray-finished machine is about to come out.

But the more so, the more the lead Qiao Chenyu frowned, because behind the smooth, a few key data and structure made him uncertain, there is no way these things appear too abrupt, there is no explanation, no argument, It seemed to pop out of a crack in the stone.

　　 When I first found out, Qiao Chenyu didn't care, so I asked Shi Jun and others to bypass it first, and wait until Chief Engineer He came back. After all, Chief Engineer He was the leader, and no one knew him better.

However, with the increasing number of abnormal data and structures, Qiao Chenyu's heart began to not calm down. He was pulled up by Mr. He with one hand. He was very clear about Mr. He's character, that is, rigorous, so rigorous that no deviation can be allowed. Even a decimal point must be deducted with justification. How can it be possible to produce so many abnormal data and structures without detailed argumentation?

So the seemingly smooth shot peening process has entered a bottleneck. There are too many abnormal data, and I can’t bypass it. In order not to delay the progress, Qiao Chenyu has no choice but to suspend theoretical research first and let Shi Jun and others work on the material. Work harder.

　　 Then I waited for Mr. He to come back to see if something went wrong that year.

He Ming rushed back to the Yonghong factory last night. After a rest night, he came to the assembly workshop early in the morning and stepped into the process room. Without greeting Qiao Chenyu too much, he picked up the information on the table and glanced at it. Then he shook his head and said something that made Qiao Chenyu shocking: "I didn't do these data and structures."
