Take Off My Aviation Era

Zhuang Jianye was really helpless when he saw this scene. Whether Liu Chun's mouth was opened or he was kissed by poisoned milk. How long has it been since then, Professor Zhao was excited twice.

　　 That is the person who has just taken the quick-acting Jiuxin pill. If Liu Chun makes a few more words, it will be a big mess.

So taking advantage of Professor Zhao’s change of tone, before reaching the kind of excitement that seemed to be soaring, Zhuang Jianye hurried forward and squeezed Liu Chun away, while stroking the old man’s back with his hand, while comforting: "Professor Zhao, don’t you Think about it, our laser welding equipment is not mature yet, at most we can weld small parts such as bearings..."

　　Zhuang Jianye wanted to continue to explain, but he lifted Professor Zhao's arm and shook it in front of him to stop Zhuang Jianye from continuing his words: "I'm fine, I'm fine, I can carry it, I can carry it~~~"

It can be carried. From the EJ9 e-book welding machine, to the silicon nitride bearing later, to the current laser welding machine, even if Professor Zhao’s old heart is fragile and now a little numb, he unscrews the portable After drinking two sips of warm water in the thermos I carried, he let out a sigh of relief: "Laser welding machine, laser welding process...good thing, really good thing..."

After speaking, he picked up the ring outside the bearing and looked at it several times carefully. He praised: "I can't even find the weld. If I don't point it out, it will be clear that these are two pieces of low carbon steel. Welded together?"

Then he gave the ring in her hand to Tong Xia next to him: "Look at it, this is the cutting-edge welding process..." As soon as the voice fell, Professor Zhao sneered: "The French think they are'dolphins' 'The aluminum honeycomb composite material on the helicopter is world-class and unparalleled in the world. During the transfer, the lion opened its mouth wide, but did not give us the relevant technology. Later, we conquered it, and we got stuck with the glueing process of changing the material, which made us very passive.

Well now, we have a laser welding process, which can directly weld the aluminum honeycomb into a whole from the inside to the outside. Its process performance is safer and more convenient than the French chemically synthesized adhesive bonding agent. More importantly, the whole The structure is still very strong, and then see if the French have any spells to recite. "

　　Professor Zhao’s words became happier. Tong Xia, who was on the side, also nodded frequently. From her appearance, she knew that she was tossed by the French in this respect.

　　 But there is no other way. Whoever makes the advanced bonding technology of aluminum honeycomb composite material impossible in the country, some people may ask that Ascendas Aviation Technology R&D Center is not very good in this area, it should be able to do it.

　　The problem is that although the Ascendas Aerospace Technology R&D Center is very strong in advanced aerospace materials, it mainly focuses on carbon fiber materials and their derivatives. Metal materials are actually very general.

　　Although the aluminum honeycomb composite material is called a composite material, the main material is still metal, but a very thin aluminum honeycomb structure is added between the two aluminum plates to enhance the structural strength of the plate.

　　 In this regard, the Ascendas Aviation Technology R&D Center can only be said to be general, and naturally there is no unique bonding process. If it is replaced with an aramid paper honeycomb structure, it is another matter.

Developed countries export technology to the outside world, mostly for cutting leeks and wool. It costs US$1,000 for a screw to open its mouth. The skillful and normal operation is normal. The imitation factory that slaughtered the domestic "Dolphin" helicopter in the glueing process is too normal. .

Professor Zhao also knows this truth, but because of this he feels very suffocated. Now it’s alright. Ascendas Group actually has a laser welding machine. You must know this precision welding process. The minimum solder joint can be controlled at about 1 micron. The aluminum honeycomb composite material The aluminum honeycomb structure is not as thin as 1 micron and can be welded by laser welding technology.

　　 The resulting effect is self-evident. It not only simplifies the production process and improves efficiency, but also reduces the pollution caused by chemical binders, making the manufacturing process more environmentally friendly.

　　 Of course, more importantly, the use of laser welding technology can achieve structural weight reduction, which is a huge benefit for any kind of aircraft.

Because of this, Professor Zhao was sincerely happy to learn that Ascendas Group owns a laser welding machine. He gave the bearing ring to Tong Xia and experienced the welding seam on it. Professor Zhao turned his head and looked at Zhuang Jianye with a smile: " Xiaozhuang, is your laser welding machine also imported from the United States?"

　　 "We really wanted to buy it, but the Yankees didn't sell it, so we had to do it ourselves." Before Zhuang Jianye could answer, Liu Chun on the side interjected first.

"The laser welding machine was developed by you yourself?" Professor Zhao changed his tone again. Zhuang Jianye felt a little bit of his heart, and touched Liu Chun with his foot, so that the old man would stop irritating, but he did not think that Liu Chun's old feet would touch Liu Chun. Told myself twice.

　　Zhuang Jianye tilted his head in surprise, and saw that the old man Liu Chun blinked at him, as if to say, rest assured, there is something between the old man, I have a sense of measure.

Zhuang Jianye, who originally wanted to stop it, shut up immediately, and listened to Liu Chun to continue: "Of course, we cooperated with the North China Institute of Optics to develop a 600W CO2 laser and developed our own laser welding based on this. We have accumulated a lot of welding data. The next step is to develop a 1000W carbon dioxide laser. Once it succeeds, it will be applied to the D-30-Z series turboshaft engine that we have just completed the initial trial..."

　　 "Wait..." Liu Chun wanted to continue but was stopped by Professor Zhao: "D-30-Z series turboshaft engines have completed the initial test run?"

Liu Chun nodded: "What happened last month~www.readwn.com~ We also reported to the light helicopter development project team. They just sent someone to look around and left after filling out a report. The way, who made us the D-30-Z series turboshaft engine is a backup power system. There is no other turboshaft with 8 red seedlings, just like our aramid paper honeycomb structure composite material, obviously better than the French. The aluminum honeycomb is an advanced generation, but the light helicopter development project team looks down on it.

Brother Zhao, don’t you know how many sins we have suffered and how much we have suffered over the years. It is said that Chollima is common but Bole does not often occur. We just don’t suffer from the loss of Bole. Grandpa doesn’t hurt, and uncle doesn’t love. What's the use of making good things? Isn't it just throwing there and smelling? But they don’t care if they are young. Those of us who come here look distressed~~"

Liu Chun’s words are both good and prosperous, and the white and fat old face is just like the seven or eight people squeezed in a small house of more than ten square meters in the Yonghong factory. Those with bitter and deep hatred can touch God. .

Professor Zhao was shocked at first. He didn't expect Ascendas Group to have so many good things in his hands, but the next moment he was agitated by Liu Chun's words. He has never seen such a bully when he has seen a bully. Thigh: "Others don't use it, I use it for the old man, Xiaotong, Xiaowu, I will draft a report at night when I go back, and officially report our helicopter project."
