Now Wang Huan and others are not calm, they have seen welding together, they have seen casting and molding, they have seen machining, and it is the first time they have seen parts that can grow on their own.

Wang Huan almost thought that there was something wrong with his eyes, took off his glasses and rubbed his eyes vigorously, not to say, took out a handkerchief and wiped the glasses again, and then put them back on and stared at the screen.

"This ...... This...... This ......"

For a moment, Wang Huan pointed to the screen, there was no reason for this for a long time, there was no way, the situation in front of him was so weird that Wang Huan didn't know what language to use to describe it.

"This is the key to our maintenance of the JT9D turbofan engine, the NB-233 integrated manufacturing equipment with the new laser additive manufacturing technology, which can directly process some special parts within 15 cm in a full vacuum environment. ”

At this time, Qiao Shiming suddenly spoke, with undisguised appreciation on his face, as if he was looking at his outstanding child, full of pride: "The reason why we were able to complete the repair of the strained crown of the low-pressure turbine blade in three days is because of this equipment. ”

"Laser additive manufacturing technology, can you directly process special parts?"

Listening to Qiao Shiming's words, Wang Huan seemed to have caught something, but he didn't seem to grasp anything, there was no way that Qiao Shiming was too general, and Wang Huan didn't understand it at all.

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

It turns out that this NB-233 is a special production equipment jointly developed by the North China Laser Research Institute merged into the Tengfei Group, and is now renamed the Tengfei Laser Research Institute and a national defense science and technology university in central China.

The original idea of the two parties was to expand the scope of application based on the laser welding machine developed by the Tengfei Laser Research Institute, and develop a high-power precision laser welding equipment for the aerospace and shipbuilding sectors.

It is used for precision welding of space launch vehicles and special welding of submarine hulls.

Such an important subject inevitably required a large number of tests, and it was found that a welding test on a high-temperature alloy vacuum environment showed that the same material of the wire could not only firmly stabilize the two parts, but also superimpose them in other directions.

This discovery is equivalent to opening a window, so that several experts involved in the development suddenly discovered that it seems that there are more options to be made in addition to laser welding.

Later, with the in-depth research and the collection of data, experts learned that the United States had begun research in this area as early as the 70s, and called this situation laser additive manufacturing technology, which is mainly used for the integrated molding of small high-temperature resistant parts of aero engines.

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

The aerospace department cannot but attach importance to this, but because this kind of information is too little, and it is a new discovery, I don't understand what the application prospect is, and its expectation is to focus on the laser welding machine, so this new discovery is only a simple support, and is not included in the focus of assistance.

But it was different in Tengfei Group, Zhuang Jianye immediately gasped after seeing the memo, laser additive manufacturing technology, this name is awkward and complicated, but Zhuang Jianye knows that this thing has another name after more than ten years, industrial 3D printing technology.

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

No drawings, no heat treatment, just simple grinding and polishing, it is the perfect usable component, properly subverting the existing manufacturing industry pattern.

If you don't support this, it's unreasonable.

As a result, Zhuang Jianye spent a lot of money and added a research and development budget of 50 million yuan, and also allocated a project bonus of 4 million yuan to the entire research and development team.

The technicians of Tengfei Laser Research Institute have long been surprised by the generosity of their boss, and although they are happy to see the funds and bonuses, they are not excited.

The technical personnel of a certain university in central China are different, even if they spend so much money, and there is also a bonus of more than 4 million yuan, which is just a preliminary discovery, and there are so many bonuses? These technicians in the ivory tower are almost crazy.

They couldn't believe it until the money fell into their hands, and 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 ready to complete this project and go abroad have changed their minds, and feel that there is not no hope in China, at least there are conscientious enterprises like Tengfei Group that respect science and attach importance to scientific research.

As a result, the enthusiasm of these university technicians was fully stimulated, and all of them threw themselves into laser additive manufacturing technology.

Tengfei Laser Research Institute took a look, where is this? They started with lasers, if this is compared to others, where will a face be put in the future? So they also use their strength to use laser additive.

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

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

The leaders of the aerospace department, who were still at a loss about laser additive technology, produced the fixed support frame of a certain type of launch vehicle in one day after seeing the first-generation prototype, and the performance of each level was completely consistent with that of similar products manufactured in the past.

The previous dissatisfaction with the two teams slowing down the development progress of laser welding immediately disappeared, you must know that although the support frame of this type of launch vehicle is not large, the design indicators are extremely high, and it is also special-shaped, large-scale production is difficult, and can only be produced in small batches alone, coupled with a series of complex follow-up processes, the general production cycle is more than one month.

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

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

Therefore, the leaders of the aerospace department immediately went to the capital to report in person after understanding the details, and soon included this cutting-edge manufacturing key technology in the national key support project, led by the aerospace department, assisted and guided by Tengfei Group, and the two teams undertook specific research and development tasks.

In this way, the laser technology officially entered the fast lane, and soon developed the second generation of products, which was named NB-233 by Zhuang Jianye himself.

This one in the Ascendas Aviation Repair Plant is the first NB-233 equipped in the Ascendas Group, which is mainly used for the integrated molding of small special-shaped parts of the aircraft, so as to improve the efficiency of aircraft maintenance.
