Chapter 1324

This passage flickered twice on the screen and then faded away. Immediately, the screen switched quickly. The production scenes of the craftsmen focused on took off one by one, and the proud achievements constantly impacted Liu Xiaolin's already surprised eyes.

"This... This... Is this the chairman's office?"

I don't know how long after that, Liu Xiaolin finally asked the question in his heart, but Zhuang Jianye replied meaningfully: "why not? You know, they are the core and pillar of China's take-off to today. Look here... "

With these words, Zhuang Jianye points his hand to the first painting at the door. On it is an old man over 50 years old who is working on the most common milling machine to process a sheet part with extremely complex curvature.

Although old, but eyes are surprisingly focused, a pair of dry and powerful hands just holding the milling machine console, steady with the tool for extremely fine processing.

Ju kuohai (1924-1996), the first craftsman of China's take-off, has been the foreman of the fitter class of Yonghong aircraft manufacturing factory, the director of the machining workshop of the 23rd branch of Yonghong factory, and the senior consultant of the aero engine manufacturing expert committee of Tengfei group

"The most powerful part of Mr. Ju is that he can use the most common machining equipment to produce extremely complex curved surfaces. At the beginning, we just reorganized from the 23rd branch factory to the Tengfei manufacturing factory, preparing to use a small turbofan on the UAV, which requires the blades of the turbofan to have a high efficiency, so as to ensure the thrust output, This requires the fan blade to have a complex curved surface to meet the design requirements.

Unfortunately, at that time, our Tengfei manufacturing plant was destitute, and there was no special processing equipment for such fan blades, let alone the production experience. Looking at this difficulty, we had to jam the whole product. Mr. Ju volunteered to take on this arduous task. "

Then Zhuang Jianye looked at the painting on the wall showing master Ju's fan blade processing. It seemed that he went back to the era of passion and entrepreneurship more than ten years ago, and slowly said again: "master Ju took a few apprentices to eat, live and work in the workshop for three months, and finally made fan blades that meet the requirements with the most common lathes, milling machines and grinders, The error precision is not more than 0.02mm, which lays the foundation for the rise of our take-off system. "

After a pause, Zhuang Jianye suddenly thought of something and added: "the fan blade processed by master Ju is the wd-20ml small turbofan engine which is widely equipped in various fields in China."

As soon as he heard that he was a breakthrough in the key technology of wd-20ml small turbofan engine, Liu Xiaolin was awed. He had no way to say which of the most famous products of China's take-off aero-engine is the WD-20 series small aero-engine which laid the foundation for China's take-off aero-engine.

It is not only widely used in cruise missiles, anti-ship missiles and UAVs, but also used as an aviation power auxiliary device certified by McDonnell Douglas company. It has obtained the airworthiness certificate of the United States and Europe, and has become the only complete mechanical product in China's hands that can be put into the international market.

Even internationally recognized, not to mention in China, WD-20 series can be seen everywhere, from the mobile power devices used to power fighter planes at airports to the small gas turbines used to drive equipment in the chemical industry.

Among other things, the s-300pmu2 air defense missile system equipped by Liu Xiaolin's former troops is almost the same as Russian products, but another item that China has not purchased from Russia is the mobile power generation equipment accompanying the missile system, because Russian products also use old diesel engines as power generation, which is not only cumbersome but also fuel consuming, More importantly, too much noise and infrared radiation is not conducive to the concealment of troops, far less compact and powerful than the domestic mobile ground station developed with WD-20 series aeroengines.

Liu Xiaolin may not know what the fan blade is, but wd-20ml is like a thunderbolt. Naturally, he has great respect for master Ju in the painting.

At this time, Zhuang Jianye's words sounded again: "he is the first craftsman to take off in China, but it's a pity that it's not too late. A few years ago, master Ju found liver cancer during his physical examination. At that time, he was in advanced stage and left in less than two months..."

With a sigh, Zhuang Jianye said again: "but we have not lost master Ju's technology, especially through the research of master Ju's high-precision machining process in lathe, milling machine and grinder, we have developed nb-38xx series high-precision composite machining center, which can truly realize automation of the work that can only be completed by master Ju's hand.

Not only that, we also named his team after master Ju. Now it's no one else who is the monitor of Ju kuohai's team. It's master Ju's Last Apprentice, and he's also one of our Chinese take-off craftsmen... "

With that, Zhuang Jianye pointed to another painting not far away.

Above is a man wearing a dust cap, wearing a dust suit, holding a laptop in his hand, staring at a curved blade in front of him like an enchanting woman.

Liu Lei (1973 -) graduated from the Department of Aeronautical Materials of Northwest Aeronautical University with a graduate degree and served as a technician in the first workshop of the aviation engine manufacturing plant of Tengfei group; Senior Research Fellow of process room of No.1 Workshop of aviation engine manufacturing plant; Ju kuohai, leader of the aeroengine manufacturing plant

"Although Liu Lei is really working in a workshop, he is a top student in a university. He could have gone to graduate school, but he didn't want to work. We thought he was a college student and couldn't bear the hardship of working in a workshop. We didn't expect that Liu Lei not only survived, but also conquered the silk laying technology of composite materials for large bypass ratio turbofan blades under his leadership, The technology of turbofan that we take off from China has been improved for 30 years, ranking among the world's advanced levels. " Liu Xiaolin can't help nodding when he hears the words. No wonder he looks at Liu Lei's oil paintings. He is not so much a worker as a technician. It turns out that what people do is really high-tech. Next, Zhuang Jianye introduced to Liu Xiaolin several take-off craftsmen, including senior craftsmen who can weld thousands of columnar circuits on integrated circuits the size of bottle caps; There are workers and experts who can control the precision of solid missile propellant within 0.02mm by using common cutting tools; There are also riveting experts who can use ordinary drills to make errors more than 0.003mm; There are also heroines who can use a mirror to find the welding dead angle of the aeroengine and ensure the deformation accuracy is no more than 0.002mm through the Mao welding process... Liu Xiaolin, a take-off craftsman, can be said to be filled with emotion. The world only sees China's take-off technology is advanced and its products are excellent, but no one explores how it is created, Now Liu Xiaolin is lucky to see all this, the inexplicable shock and moving can hardly be described in words. At this time, Zhuang Jianye sighed: "some people say that I'm too hard-working, but Lao Liu, look at these characters in the oil painting. They are quietly dedicating their youth, contributing their blood and sweat, and condensing so little achievement. If no one goes to fight, no one's conscience will be stable, so don't blame me for being so persistent in anti missile, I'm not for myself, what I'm doing is for them... "He said, pointing to the oil paintings on the wall:" for the fruits of their hard work, I want to belong and get a place. Lao Liu, don't you think I should? "
