Original title: Science and technology leader Sun Xiaoxia keeps improving, only for product innovation and upgrading (introduction)
"Acceleration" for initiating explosive device development (theme)
Worker's Daily - reporter Liu Xu from China Industrial Network
"I have witnessed one initiating explosive device after another changing from drawing to product." Sun Xiaoxia's pace is fast and steady on the path from the employee innovation studio to the assembly workshop. On the way of catching up with the "acceleration" of China's high-tech product Feitian Navigation Drilling, she has been going for 27 years.
Initiating explosive device is a general term for disposable components and devices that contain gunpowder or explosives and generate combustion or explosion after external stimulation to ignite gunpowder, detonate explosives or do mechanical work. The initiating explosive device designed by Sun Xiaoxia, the leader of China's weaponry science and technology, and the researcher of the Initiating Explosive Device Technology Research Institute of Liaoning North Huafeng Special Chemical Co., Ltd., a special energy group, is used in the research and development of more than 10 national key initiating explosive device research projects, such as aircraft carriers, fighter planes, missiles, etc. She has tackled more than 30 key technologies of initiating explosive devices and more than 10 technological problems, creating an output value of more than 100 million yuan.
In recent years, with the continuous improvement of the modernization level of China's weapons and equipment, China Weapon Special Energy Group has undertaken the important mission of initiating explosive devices development and production, and worked hard to build a national origin of initiating explosive devices original technology. Sun Xiaoxia, as a technical backbone, has made positive contributions. This year, Sun Xiaoxia was awarded the National May Day Labor Medal.
Let the reliability from 0.99 to 0.9999
When entering the assembly workshop, the workers filled the chemicals orderly. Sun Xiaoxia said, "The initiating explosive devices we developed and produced will be used in important parts of launch vehicles and spaceships. They should not only be anti vibration and anti electromagnetic interference, but also be resistant to cold, humidity and heat. They can also work normally in extreme environments."
Sun Xiaoxia, who had just arrived at her post and graduated from a chemical engineering major, didn't know what a fire cap or lighter was, so she had to start from scratch. In order to get started quickly, she learned from her teacher and filled with the workers. In order to improve her knowledge and skills, she insisted on working part time and studying part time after entering the factory, and often had to take more than 20 hours of green trains to and from Fushun and Nanjing. She studied the technical route, worked out the test plan, and wrote a paper... She obtained a master's degree in weapon engineering from Shenyang University of Technology in three and a half years, and a doctor's degree in weapon engineering and technology from Nanjing University of Technology in five and a half years.
Sun Xiaoxia still remembers that she felt uneasy when checking and accepting a product designed for the first time. When more than 10 indicators, such as status, size, resistance, function and operating environment, were qualified, her heart fell. In order to get rid of this anxiety, she spent a lot of time and energy studying. With project problems in her mind, she will write down her ideas at any time, and study when inspiration comes, so that the reliability of some initiating explosive devices used in the aerospace field can be improved from 0.99 to 0.9999.
The Olympic solid torch on Mount Everest, which she participated in the development of, was ignited and burned reliably for the first time under the extremely severe weather conditions of low temperature, low pressure, strong wind, and snow on the top of Mount Everest, and will be forever recorded in the history of the Olympic Games.
Continuous efforts are only for innovation and upgrading
"In the past, one model on the production line was able to work for several years, but now one or even several models are updated every year." Recently, Sun Xiaoxia and her team have been busy in the research and development front line, carrying out product innovation and optimizing the process flow, "we keep working hard to innovate and upgrade initiating explosive devices only."
Sun Xiaoxia is responsible for the development of charge components for ignition of a missile engine. The innovative design of high-temperature resistant coating structure and multi loading and multi pressure charge structure has realized high-energy ignition under low temperature and low pressure environment, and the overall technology has reached the international advanced level; Responsible for developing a national key engineering model project. After several tests of various schemes, the bottleneck problem of poor reliability under high temperature was overcome, and the technical problem of non failure and reliable function under 250 ℃ high temperature was solved. The two types of products were produced in batches, creating an output value of more than 50 million yuan; I was responsible for a key scientific research project of Ordnance Industry Group, and innovatively designed the ignition series of sensitive fast ignition composition - high-energy sealed ignition composition - fast burning rate delay composition - slow burning rate tungsten delay composition (body), which realized the delay function of high-precision long second measuring gunpowder
When talking about how to achieve high-frequency R&D innovation, she mentioned three key words: continuity, detail and source. In order to stay ahead of the industry, she spent a lot of leisure time "brushing" papers, browsing tens of thousands of papers and downloading thousands of papers. In order to ensure the feasibility of her design, she never missed every parameter and detail on the drawing. In order to ensure the safety and reliability of products, she insists on the reasonable source of structural design and process design. She has to track the whole process from drawing, assembly to acceptance, so that the initiating explosive device developed from this can work accurately.
Bring out the team and dare to fight "hard battle"
"It is the organization that has cultivated me, the people's military spirit has nourished me, the enterprise has provided me with a platform for scientific research and innovation, and I am also willing to do a good job of" mentoring "." In the staff innovation studio led by Sun Xiaoxia, the reporter saw a lot of achievements: in the past three years, 10 scientific and technological achievements have been made, 47 patents have been obtained, and 45 professionals have been trained, Two people were rated as science and technology leaders of North Special Energy Group Co., Ltd., one was rated as young science and technology leaders of North Special Energy Group Co., Ltd., and many people took middle leadership positions
"Every innovation and progress of scientific researchers here is supported by a corresponding incentive system. When we harvest the achievements of scientific and technological progress, we realize our own value," said Zhang Ximin, deputy secretary of the Party Committee and chairman of the trade union of Liaoning North Huafeng Special Chemical Co., Ltd. of China North Weapons Special Energy Group, proudly. In 2022, CNIGS Liaoning North Huafeng Special Chemical Co., Ltd. provided more than 200 sets (pieces) of space initiating explosive devices for key segments of the space station, Shenzhou manned spacecraft, Tianzhou cargo spacecraft, some satellites and rockets, all of which played a key role and played a reliable role. This is because Sun Xiaoxia and other R&D and design personnel strictly control the quality in all aspects and strive for perfection.
Sun Xiaoxia said that she and the R&D team are still working hard on the new journey of building a national origin of original initiating explosive device technology and building a scientific and technological first-class enterprise. "We are all dreamers".
