The first time I got to know Xu Liping was the role played by Zhang Ziyi in the movie me and my father's generation. In the movie, Zhang Ziyi carefully holds the plastic surgery knife and carefully scrapes the side wall of the gunpowder, which is Xu Liping's work - the micro-shaping work of the solid power fuel medicine surface of the aerospace engine.
This work is mainly to micro-shape the gunpowder of the missile's solid fuel engine. Solid-fuel engines are the strategy
This work is mainly to micro-shape the gunpowder of the missile's solid fuel engine. The solid fuel engine is the heart of strategic and tactical missile equipment, and it is also a key component for launching manned spacecraft rockets, and its manufacturing process has thousands of processes, and one of the most demanding processes is the micro-shaping of the solid fuel of the engine. Carving solid fuel, that is, gunpowder, is extremely dangerous, and the slightest carelessness will rub out sparks, burn instantly, and even cause explosions. But Xu Liping has been engaged in this dangerous work since 1987 until now. 0.5 mm is the maximum error allowed by the accuracy of the solid engine powder surface, and the error of the gunpowder surface that can be carved by Xu Liping's hand does not exceed 0.2 mm, which is perfect, which makes his master unattainable.
In this dangerous and highly toxic working environment, Xu Liping's body is gradually deteriorating: prolonged exposure to gunpowder in a confined space causes Xu Liping's legs to lose consciousness, his body tilts to one side due to long periods of time carving in the same posture, and his hair is also lost in half. However, under such environmental and physical conditions, Xu Liping himself invented and designed more than 20 kinds of pharmaceutical surface plastic surgery knives, and even two of them obtained national patents, in order to eliminate safety hazards. Because Xu Liping is willing to be lonely and calm and exquisite, he is known as a "big country craftsman".
"A big country has many good materials: every time you drop the knife, you can hear your own heartbeat." You have carved a small amount of gunpowder, and there can be no difference. Strategic missiles, manned spaceflight, and every weapon of a great power are inseparable from you. It's like a knife in your hand, forged in twenty-six years. You are a craftsman, you are a craftsman of a great power." This is the evaluation of Xu Liping by the host when the Chinese award was given, and I think this evaluation is not only an endorsement of Xu Liping, a skilled "art" master, but also a recognition of the staff who have silently paid a lot of effort for the aerospace industry behind the scenes.
