Zhuang Jianye really couldn't complain when he saw this scene. Did Liu Chun, the old guy, have his mouth opened or was he kissed by poisonous milk? Professor Zhao was excited twice just after he came here.
¡°That¡¯s a person who has just taken the Su-acting Jiuxin Pill. If Liu Chun gets over it with a few words, there will be big trouble.
So taking advantage of the change in Professor Zhao's tone, before he reached the excitement that seemed to rise, Zhuang Jianye hurriedly stepped forward, pushed Liu Chun away, rubbed the old man's back with his hand, and comforted him: "Professor Zhao, please don't If you think about it, our laser welding equipment is not yet mature, and at most we can only weld small parts such as bearings"
Zhuang Jianye wanted to continue explaining, but Professor Zhao raised his arm and waved it in front of his face to stop Zhuang Jianye from talking: "I'm fine, I'm fine, I can handle it, I can handle it~~~"
I can't bear it. From the ej9 e-book welding machine, to the later silicon nitride bearings, and now to the current laser welding machine, even Professor Zhao's old heart is a little numb now, so he unscrews the After taking two sips of the warm water in the thermos cup I was carrying, I breathed a sigh of relief: "Laser welding machine, laser welding processgood stuff, really good stuff"
Then he picked up the ring outside the bearing, looked at it carefully several times, and praised: "I can't even find the weld. If I didn't point it out, how would I know that these are two pieces of low carbon steel?" Welded together?¡±
Then he handed the ring in his hand to Tong Xia beside him: "Look at it, this is the cutting-edge welding technology" As soon as he finished speaking, Professor Zhao sneered: "The French think they're dolphins 'The aluminum honeycomb composite material on the helicopter is world-class and unparalleled. During the transfer, the lion opened its mouth and refused to give us the relevant technology. Later, we overcame it and blocked us from changing the bonding process of the material, which made us very passive.
Well now, we have a laser welding process that can directly weld the aluminum honeycomb into a whole from the inside out. Its process performance is safer and more convenient than the French chemically synthesized adhesive. More importantly, the whole The structure is still very solid, and it will be up to the French to see what spells they can recite. "
Professor Zhao¡¯s words became more and more cheerful as he spoke. Tong Xia on the side also nodded frequently. It was clear from her appearance that she had been tormented by the French in this regard.
But there is no way. Who knows that there is no advanced bonding technology for aluminum honeycomb composite materials in China? Some people may ask, if 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 Tengfei Aviation Technology R&D Center is strong in advanced aerospace materials, it mainly focuses on carbon fiber materials and their derivatives. Metal materials are actually very average.
Although aluminum honeycomb composite materials are called composite materials, the main material is actually metal. It is just that an extremely thin layer of aluminum honeycomb structure is added between two aluminum plates, thereby enhancing the structural strength of the plates.
In this regard, Tengfei Aviation Technology R&D Center can only be said to be average. Naturally, it does not have a unique bonding process. If it is replaced by an aramid paper honeycomb structure, it will be a different matter.
Developed countries export technology mostly for the purpose of cutting leeks and shearing sheep. It costs a thousand dollars to open the mouth of a screw to operate normally. It is normal for domestic replica factories of the "Dolphin" helicopter to ruthlessly slaughter the domestic "Dolphin" helicopter in terms of bonding technology. .
Professor Zhao also knows this truth, but he also feels suffocated because of it. Now it¡¯s better. Tengfei Group actually has a laser welding machine. You must know that with this precision welding process, the smallest solder joint can be controlled to about 1 micron. In aluminum honeycomb composite materials, The aluminum honeycomb structure is thin and light, less than 1 micron, and can be welded using 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 when he learned that Tengfei Group had a laser welding machine. He handed the bearing ring to Tong Xia to experience the welds on it. Professor Zhao turned to look at Zhuang Jianye with a smile: " Xiaozhuang, are your laser welding machines also imported from the United States?"
"We really want to buy it, but unfortunately the Americans won't sell it, so we have to do it ourselves." Before Zhuang Jianye could answer, Liu Chun on the side jumped in.
"Did you develop the laser welding machine yourself?" Professor Zhao changed his tone again. Zhuang Jianye felt a little bit in his heart and touched Liu Chun with his foot to tell the old guy to stop irritating him, but he didn't want to touch Liu Chun's old foot in turn. He hit himself twice.
Zhuang Jianye tilted his head in surprise and saw Liu Chun blinking at him.?As if to say, don't worry, Lao Liu, I have a sense of control over the matters between the old men.
Zhuang Jianye, who originally wanted to stop him, immediately shut up, and then heard Liu Chun continue: "Of course, we cooperated with the North China Institute of Optics to develop a 600w carbon dioxide laser, and based on this we developed our own laser welding Machine, we have accumulated a lot of welding data, and the next step is to develop a 1000w carbon dioxide laser. Once successful, it will be applied to the d-30-z series turboshaft engine that we have just completed the initial test run"
"Wait a minute" Liu Chun wanted to continue but was stopped by Professor Zhao: "Has the d-30-z series turboshaft engine completed its initial test run?"
Liu Chun nodded: "We reported what happened last month to the light helicopter development project team. They just sent someone to look around, filled out a report and left. There was nothing we could do. Who made us? The d-30-z series turboshaft engine is a backup power system. It is not as good as other people's turboshafts with 8 red seedlings. Just like our aramid paper honeycomb structure composite material, it is obviously one generation more advanced than the French aluminum honeycomb. But the light helicopter development project team looked down upon it.
Brother Zhao, you don¡¯t know how much we have suffered and how much suffering we have suffered over the years. It is said that thousand-mile horses often exist but Bole does not always exist. We just suffer the loss of not having Bole. Grandpa does not love us and uncle does not love us. What¡¯s the point of making something good? Why don't you just leave it there and stink? But they are young and don¡¯t care, but those of us who have been there feel heartbroken~"
What Liu Chun said was a perfect combination of words and deeds. His white and plump old face was twitching just like the seven or eight people who were crowded into a small room of more than ten square meters in the Yonghong Factory. Even those who suffered greatly and had deep hatred could move God. .
Professor Zhao was shocked at first. He didn't expect that Ascendas Group had so many good things. But the next moment, he was made angry by Liu Chun's words. He had never seen a bully before, so he immediately slapped him. Thigh: "Others don't use it, but I, the old man, Xiao Tong and Xiao Wu will draft a report when we get back in the evening and formally submit our helicopter project."
