I hope you will bear in mind your mission and responsibility, firmly uphold the aspiration of aviation to serve the country, promote the spirit of model workers and craftsmen, strive to conquer more key core technologies, accelerate the pace of independent development of aviation engines, and make China's aircraft use a stronger "Chinese heart", actively contributing to building an aviation power and achieving high-level technological self-reliance and self-reliance. Liming Engine Assembly Plant is subordinate to Shenyang Liming Company of China Aviation Development Group. When the company was founded in 1954, it set up an engine assembly team. In 2013, it was renamed after Li Zhiqiang, a national model worker and national technical expert. ——The editor firmly completes the tasks entrusted to us by the country, which is an important manifestation of a country's scientific and technological strength and innovation ability. The development of aviation engines is difficult, time-consuming, and has a high technical threshold. As the heart of an aircraft, an advanced aviation engine is composed of tens of thousands of components with various types, special materials, and different shapes. The external pipelines around the body are like the blood vessels of the engine. For assembly work, precision is extremely high, and there is no room for any mistakes, "said Li Zhiqiang, a senior technician at China Aerospace Group Shenyang Liming Company. In 1983, at the age of 19, Li Zhiqiang retired from the military and came to the factory with the ambition of serving the country through aviation. The transition from a soldier to an aircraft assembler is very difficult, as the distance is like a mountain. Faced with difficulties, Li Zhiqiang did not flinch at all. He carried a pen and notebook with him every day, and whenever he had time, he followed the teacher Fu to learn. If he didn't understand, he would ask, and if he didn't know, he would remember. He also took the time to self-study all the professional courses related to mechanical assembly and all the courses related to management at TVU. After more than 10 years of research and development, Li Zhiqiang has become an expert in aviation engine assembly, known by colleagues as the "living drawing" and "living standard" of engine assembly. The research on the assembly process of aviation engine pipelines, written by him summarizing technical essentials, has become a mandatory textbook for every assembler in the factory. The installation of the flight attachment gearbox is one of the difficulties in aviation engine assembly. It is not only large in size, but also installed in the belly of the engine. In the past, assembly usually required cooperation from multiple people, which not only consumed manpower but also made it difficult to ensure quality. Wen Shangzhi, the current monitor of the "Li Zhiqiang Class", is determined to overcome this problem. He led the team members to use their lunch break and evening time to search for information, principles, and equipment. After repeated experiments, he finally successfully found an operation method that not only saves manpower but also improves efficiency, and obtained technical recognition from the expert group. Solve any problems, conquer any difficulties, and resolutely complete the tasks assigned to us by the country, "said Li Zhiqiang. In recent years, with the continuous enrichment of products, facing various types with more precise structures
