Take Off My Aviation Era

Now Wang Huan and others are not calm. They have seen welding together, seen casting molding, seen machining, and this is the first time that they have seen parts grow by themselves.

Wang Huan almost thought that there was something wrong with his eyes. He took off his glasses and rubbed his eyes vigorously. He took out his handkerchief and wiped the glasses again. Only then did he put it on and stared at the screen again, only to realize that it was not his own. There was something wrong with the eyes, but the parts in the workbench were growing upwards. Although it was slow, the growth was not possible.

"This...this...this..."

For a moment, Wang Huan pointed to the screen. It has been a long time since there was no such thing. There is no way. The situation is so strange that Wang Huan doesn't know what language to describe.

"This is the key to our repair of the jt9d turbofan engine. The nb-233 integrated manufacturing equipment using the new laser additive manufacturing technology can directly process some special parts within 15 cm under a full vacuum environment."

At this time, Qiao Shiming suddenly spoke, with undisguised appreciation on his face, as if he was watching his outstanding child, full of pride: "The reason why we can complete the strained crown repair of the low-pressure turbine blades in three days, with This is the device."

"Laser additive manufacturing technology? Can special parts be processed directly?"

After listening to Qiao Shiming's words, Wang Huan seemed to have caught something, but he didn't seem to be sure of anything. There is no way that Qiao Shiming's words were too general, and Wang Huan did not understand at all.

Fortunately, Zheng Yongning played a role at this time and started to do some simple science popularization.

Originally this nb-233 was incorporated into the North China Laser Research Institute of Ascendas Group, and now it is renamed as a special production equipment jointly developed by Ascendas Laser Research Institute and a certain National University of Defense Technology in Central China.

The initial idea of ​​the two parties was to develop a high-power precision laser welding equipment for the aerospace and shipbuilding departments based on the laser welding machine developed by Ascendas Laser Research Institute.

Used for precision welding of space launch vehicle and special welding of submarine hull.

Such an important subject inevitably requires a lot of experiments. As a result, after a welding test on high-temperature alloys in a vacuum environment, it was found that the welding wire of the same material can not only firmly stabilize the two parts, but also can be superimposed in other directions of the parts.

This discovery was tantamount to opening a window, and several experts involved in the development suddenly discovered that it seemed that there were more options for laser welding.

Later, with the in-depth research and the collection of data, the experts learned that the United States had already begun research in this area as early as the 1970s, and called this situation laser additive manufacturing technology, which is mainly used for small aero engines with high temperature resistance. Integration of components.

With the discovery and the source, the two development units immediately formed a memorandum to report upward.

The aerospace department cannot help but pay attention to this, but because there are too few such materials and new discoveries, they do not understand the application prospects, and their expectations are focused on laser welding machines, so this new discovery is just a simple support. It is not included in the focus of assistance.

But in the Ascendas Group, Zhuang Jianye immediately took a breath after seeing the memorandum. The name of laser additive manufacturing technology is mouth-watering and complicated, but Zhuang Jianye knows that this thing will have another pull ten years later. The name of the wind, industrial 3d printing technology.

Especially with the development of the computer level, industrial design software becomes more and more refined, and with this kind of industrial 3D printing technology, those complex parts that used to require multi-axis machine tools and superb technology, as long as the design software on the computer is finalized, It can be produced on high-level industrial 3d printing equipment.

No drawing, no heat treatment, just simple grinding and polishing, it is a perfect usable part, which properly subverts the existing manufacturing industry pattern.

It would be unreasonable if this is not supported.

As a result, Zhuang Jianye has lost his blood, and in addition to an additional R&D budget of 50 million, he also allocated a project bonus of 4 million to the entire R&D team.

The technicians of Ascendas Laser Research Institute have long been surprised at their boss Zhuang's generosity. Although they are happy to see the funding and bonuses, they are not excited.

The technical staff of a university in Central China is different. It doesn't matter if you spend so much money, there is a bonus of more than 4 million yuan. It's just a preliminary discovery, so there are so many bonuses? The technicians in these ivory towers were almost crazy.

Until the money fell into their hands, they couldn't believe it. They still thought they were dreaming, because many people had never seen so much money in their lives.

For this reason, many people who are going to complete the project to go abroad have changed their minds. They feel that there is no hope in China. At least there are conscientious companies like Ascendas Group that respect science and value scientific research.

As a result, the enthusiasm of the technicians in these universities was fully stimulated, and they all fell on the laser additive manufacturing technology.

Take a look at Ascendas Laser Research Institute, where can I go? They started with lasers. If this is compared to others, where will they put their faces? So I also used milk to add to the laser.

As a result, the two parties have implicitly formed a certain competitive relationship in this technical field, and at the overall level, they cooperated with each other. Coupled with the investment of real money, progress can be described as rapid.

The trial production of the first generation prototype was quickly completed.

The leader of the aerospace department, who was still at a loss for laser additive technology, produced a fixed support frame for a certain type of launch vehicle within a day after seeing the first-generation prototype, and its various levels were compared with similar products manufactured in the past. After being completely consistent in performance.

The dissatisfaction with the two teams slowing down the progress of laser welding development immediately disappeared~www.readwn.com~ You must know that although the support frame of this type of launch vehicle is not large, the design index is very demanding, and it is still special-shaped and mass-produced. Difficult, only small batches can be produced individually, coupled with a series of complicated follow-up processes, the general production cycle is more than one month.

But now with laser additive manufacturing technology, one can be produced in just one day.

This efficiency may be maddeningly slow in other industries, but in a sophisticated industrial category such as the aerospace field, complex key components can be produced in one day, and that is a super-class magical existence.

Therefore, the leaders of the aerospace department immediately went to the capital to report after learning the details, and soon included this key cutting-edge manufacturing technology as a key national support project, led by the aerospace department, assisted by the Ascendas Group, and the two major The team undertakes specific development tasks.

In this way, the laser-forming technology officially entered the fast lane, and soon developed a second-generation product, named nb-233 by Zhuang Jianye himself.

This unit of the Ascendas Aviation Repair Factory is the first nb-233 equipped in the Ascendas Group, which is mainly used for the integrated molding of small special-shaped parts of aircraft, thereby improving the efficiency of aircraft maintenance.
