Gao Fenglin, First Affiliation of China Aerospace Science and Technology Corporation: Welding Master of Rocket Engine

The engine is the "heart" of the rocket, the engine that takes off, and Gao Fenglin is the person who welds the "heart" of the rocket. After graduating from the technical school in 1980, Gao Fenglin has been engaged in the welding of rocket engines. Over the years, it has overcome more than 200 difficulties, saved or avoided economic losses of more than 35 million yuan, and made outstanding contributions in this position.

Hard ability, welding rocket heart

Excellent completion of the welding of the largest all-arrow vibration test tower in Asia; repairing the Soviet-made 154 aircraft engine; being taught by Professor Ding Yuzhong, successfully solved the problem of the anti-matter detector project... Gao Fenglin's resume records many brilliant moments, and these moments It is closely linked to the development of the national space industry.

In the 1990s, the new large thrust hydrogen-oxygen engine designed for the Changjiajia series of launch vehicles, the welding of large nozzles once became the bottleneck of development. X-ray inspection showed that there were more than 200 cracks in the welded joint at that time. At the high-level quality analysis meeting, Gao Fenglin, in the voice of many technical experts, boldly bluntly expressed his thoughts as “false cracks”. After a sectioning test, a 200-fold microscope showed that his judgment was correct. The “death penalty” of the first large nozzle was rectified, saving expensive products and saving the country’s economic losses. In the subsequent research project on the reliability growth of the engine system, Gao Fenglin participated in the demonstration and personally implemented it. Among them, the large nozzle completed by his main welding has passed the assessment of more than 10,000 seconds of interviews and became a “gonggong” spray. tube.

For more than 30 years, Gao Fenglin has always adhered to the country's priority, rooted in the line, dare to climb, and willing to sacrifice, and once again overcome the world-class difficulties in engine nozzle welding technology, for the national key projects such as Beidou navigation, 嫦娥 嫦娥, and manned space flight. The smooth implementation and the development of the new generation of launch vehicle for the Long March 5 have made outstanding contributions.

Love to study, Gan is a scorpion cow

Gao Fenglin was dubbed as a person who married a product. His love for the aerospace industry and his own position has been integrated into the bones. Foreign-funded enterprises have hired him with high salary and housing, but Gao Fenglin is unmoved. He persists in the aerospace industry and puts his personal interests out of the way. He does not count on gains and losses, and he concentrates on his work. In order to practice basic skills, he takes it when he eats. The chopsticks are trained to send silk. When drinking water, the cylinders filled with water are used to practice stability. When resting, the iron blocks are used to exercise endurance, and the high temperature is observed to observe the flow of molten iron. In order to meet the launch of large-capacity, large-tonnage satellites abroad, China has built Asia's largest full-arrow vibration test tower. In order to ensure the best performance of the vibration beam, it is necessary to continue operation at high temperatures, and the surface temperature of the weldment is several hundred degrees Celsius. Gao Fenglin's hands were baked to swell a string of blisters. He insisted on sticking his teeth and eventually welded out the qualified vibrating girders. In the next ten years, the vibrating beam has withstood the test of time, and his hand still has scars left by serious bruises. In the first large nozzle welding, Gao Fenglin often had to maintain an unbearable welding posture. One welding was one hour, and every night worked until three or four in the middle of the night. When he returned home, his waist and arms were nearly numb. Relieve pain. After 30 days and nights of research, the weld processing of nearly a thousand meters was completed. In order to overcome a key national key project, he spent nearly half a year on the cold products, and his joints were numb and blue.

Bring talents, preaching and practicing skills

Gao Fenglin will teach his skills as another important mission of his own. The “welding and educating method” created by the “teachers and teachers” and “one belt one” advocated by him has been widely recognized and applied in practice. His apprentice has won many achievements in the domestic and international welding competitions. So far, he has cultivated 5 national technical experts, 1 central enterprise technical expert and 1 aerospace technical expert. He has published more than 30 papers in various journals. Every year, more than 120 class hours of theoretical and practical lectures, thousands of audiences and students.

Gao Fenglin has been the leader of the argon arc welding team in the engine workshop since 1993 and has been in business for 22 years. In 2005, the team was jointly named the “Gao Fenglin Team” by the National Defense Post and Telecommunications Association and the Aerospace Science and Technology Corporation. It became the first team in the First Academy of Aerospace to be named after the model worker. Since then, the team has won many honorary titles such as “National Worker Pioneer”, National Learning Excellent Team, National Safety Production Demonstration Team, and Central State-owned Enterprise Learning Red Flag Team “Benchmark”. In 2011, as one of the 50 master skills studios named by the Ministry of Human Resources and Social Security, Gao Fenglin National Skill Master Studio was officially listed and became a talented talent cultivation base.
