Take Off My Aviation Era

"Take off my aviation era ( to find the latest chapter!

Hearing Zhuang Jianye’s words, Aziz couldn’t help but stunned, but the corners of his mouth turned unconsciously at the next moment and shook his head: “Mr. Zhuang, I can admit that your Ascendas Group is a leader in the global laser field, but There is an industry consensus, I think you should be clear, that laser processing technology is not suitable for micro-precision processing in the aviation field."

After a pause, the middle-aged man next to Aziz immediately handed a bottle of soda with respectful hands. Aziz took it indifferently and took a graceful sip. Then he cleared his throat and continued, "I It is undeniable that if under extreme circumstances, the use of lasers can process qualified products that meet the conditions, but this single measure is not reproducible, and in layman's terms it does not conform to the method of industrialized production..."

Aziz is worthy of being a senior expert who has spent most of his life in the European aviation technology circle. Whether it is theory or practice, his knowledge and experience are impeccable.

Not to mention anything else, but just a laser processing. This is not a partial one in the field of aerospace manufacturing, but it is definitely not a mainstream manufacturing process. Aziz can speak up and down, which shows the person’s aerospace technology. It's pretty good.

The aviation experts from the UAE and Algeria, who gradually gathered because of Aziz’s dialogue with Zhuang Jianye, also nodded in agreement after hearing Aziz’s words.

Not to mention being a great outsider, even a few of the Air Force experts in the army who accompanied the head of the headquarters agreed with Aziz's statement, frowning and worrying.

Therefore, Aziz’s statement is not only correct, but also very correct. In a sense, it has become a recognized consensus in the industry.

The implementation is also true. Laser processing technology, especially precision hole processing, does have unparalleled advantages over other processing methods, such as simple operation, low cost, and convenient efficiency.

But it also has its own insurmountable shortcomings, that is, the wavelength of the laser is too large and the pulse is too high, which causes the surface temperature of the drilled part to be too high, which easily leads to excessive internal thermal stress around the process hole, and the surface is recast to be thick and thick. Fine cracks are formed around the process hole.

Civil components that do not require high structural strength are nothing, but in the strict aerospace manufacturing field, let alone cracks, excessive internal stress may cause structural fatigue of the components, and a sharp reduction in life will threaten the flight safety of the entire aircraft. .

With more sophisticated aero engines, these shortcomings are even more intolerable.

Because of this, laser processing technology is generally used for cutting or welding in the aviation manufacturing industry, of course, recently there has been an addition of additive manufacturing.

But no matter which one is, it is far from hole machining, especially micro-precision craft hole machining.

Needless to say, when Ascendas previously processed the film cooling holes of turbine blades, it did not use lasers. Instead, it adopted a manufacturing technology called electrochemical perforation. The advantage is that the film cooling holes can be completed at one time. Processing does not need to do other processing.

The problem is that the electrochemical perforation process has been the production technology of Ascendas Group five years ago. Now that the Soviet Union has disintegrated, the world structure has changed. Ascendas Group’s employees have to leapfrog into the next century with the old calendar, and cannot compete with Keep up with the times?

"Well, Mr. Aziz, as well as experts, let's move to the production workshop of our WC-8 honeycomb combustor to see if our NB-6600DL ultra-precision laser hole making machine can Realize what you call industrialized mass production."

After Aziz used the elegant royal conception to popularize the knowledge that laser processing is not suitable for precision hole processing in the world aviation industry, Zhuang Jianye did not refute, but smiled and said a proposal, and then he moved to the other side first. Walked to the door.

"His Royal Highness Abdullah, His Highness Mahmoud, should we also follow him to see?" Seeing Zhuang Jianye stepping away, the head of the headquarters immediately extended an invitation to the two real people who spoke to him.

How could Abdullah and Mahmoud reject the real boss, the head of the headquarters, and immediately nodded, chatting and laughing with the head of the headquarters, and slowly left with Zhuang Jianye.

Seeing the two majesty walking away, Aziz and others had to follow along with them even if they didn't want to go. What's more, they were also very curious about what kind of equipment is the NB-6600DL ultra-precision laser hole making machine in Zhuang Jianye's mouth? Can it really break the consensus of the aviation industry that is comparable to truth for many years?

So one by one hurriedly followed, and walked around for about five or six minutes, and finally came to a factory built of reinforced concrete, and then went through several procedures such as refurbishment, dust removal, disinfection, and sterilization. When everyone enters the workshop, they are all dust-proof suits and goggles, which look like those carved in a mold from a distance.

However, Aziz and others did not find it bothersome, but when they stepped into the workshop, they were shocked by the two extremely sophisticated equipment in front of them.

I saw a machine with the words NB-6600DL drawn on the facade in front of me. The equipment was about 5 meters long, 3 meters wide, and 2.5 meters high. On the left is the processing area, where there are five WC-8s in a row. A type honeycomb combustor flame tube, on which a flexible laser is facing one of the flame tubes, uses a high-energy laser to accurately make process holes.

However, this is not surprising to Aziz and others. After all, people like this laser drilling equipment have seen a lot of them in Europe and the United States, and even some of their home countries have laser processing equipment. What makes them truly incredible is the observation window on the right side of the device for observing the operation of the internal mechanism of the device~www.readwn.com~ I really don’t know it. It is enough to startle people in the industry like Aziz. Seeing that every time the device is operated, the light source inside the device undergoes extremely complicated refraction, reflection, and finally perfusion into the laser to form a high-energy pulse.

"This mechanism is...is...is...lithography machine..."

A well-informed Algerian expert curled his eyebrows and pondered for a moment, always wondering where he had seen this institution before. After thinking for a while, his eyes opened wide and he shouted in surprise.

"This gentleman is really knowledgeable. He even knows the mechanism of the lithography machine. Our NB-6600DL can't compare to the real lithography machine. It can do the abnormal level below 193 nanometers. Ours The NB-6600DL can only compress the laser to 355 nanometers, which is half the difference."

Before the middle-aged expert spoke, Zhuang Jianye walked over with a stack of documents smiling, and while talking, he handed the documents in his hand to Aziz: "Mr. Aziz, this is just finished processing. The random sampling test results of the micro-precision process holes of the flame tube, a total of 1182 holes, there is no internal thermal stress, recast layer and cracks. Of course, if you don’t believe it, there is our inspection room, which contains the world today. The most sophisticated testing equipment in the world, you can choose from these products at once or inspect them together."

Zhuang Jianye appeared to be very generous, but Aziz didn't even listen to what Zhuang Jianye said, because his whole body was shaken by Zhuang Jianye's previous sentence. He didn't react until Zhuang Jianye finished speaking, and asked Nene: " Mr. Zhuang, how much do you think your NB-6600DL can compress the laser wavelength to? 355 nanometers?"
