On the morning of January 8, 2019, the 2018 National Science and Technology Awards Conference was grandly held in the Great Hall of the People in Beijing. Party and state leaders attended the conference and presented awards to the winning representatives.
Northwestern Polytechnical University won two national scientific and technological awards in 2018. Among them, the "Special Functional Alloy Materials for Aero Engines" project of Professor Zhou Wancheng's team won the second prize of National Technology Invention Award, and the "Key Technology and Equipment for Large-scale Functional Wall Panel Automatic and Accurate Assembly" project of National Aeronautics and Astronautics Assembly Research Institute won National Science and Technology Progress Award 2. Wait for the prize. Professor Zhou Wancheng and Zhang Kaifu, as award-winning representatives, were cordially received by party and state leaders.
The high-performance high-temperature functional alloy material developed by Professor Zhou Wancheng's team is a landmark new material for the development of modern equipment across generations, and its application level directly affects the performance of China's aircraft, ships and other equipment. With the strict technical blockade abroad, Professor Zhou Wancheng led the team out of a path of completely independent innovation. After 22 years of arduous research, he successfully researched a complete series of high-temperature functional materials, filling the domestic gap and reaching the international advanced level. The team has won 1 first prize for national scientific and technological progress, 1 first prize for national defense technology inventions, 1 first prize for military scientific and technological progress, 1 major military science and technology achievement award during the 11th Five-Year Plan period, and 2 provincial and ministerial levels There are more than ten third-class awards, more than 300 academic papers published, more than 300 times indexed by SCI, and more than 50 national and national invention patents authorized.
The large functional wall panel developed by the Aerospace Assembly Research Institute team is an external safety barrier for large aircraft, carrier rockets and other major models, and is the key to determining its service performance. Traditional small structure wall panels use a rigid assembly method based on coordinated dimensional accuracy. However, this method can lead to fatal problems such as connection quality defects. The Aeronautics and Astronautics Assembly Research Institute team lasted 11 years, breaking foreign blockades, and established a functional panel accurate assembly theory for dynamic load tracking measurement and control; and proposed a “transient induced load control” panel panel defect precise control method and “point-surface equilibrium” "Loading" of the wall surface precision control method; independently developed and put into production 11 sets of functional wall plate automatic precision assembly equipment. The research results are applied to a number of major aerospace models such as C919 and ARJ21. The overall technology is internationally advanced, and some key technical indicators are better than similar foreign technologies, which has promoted the leapfrog development of China's aerospace models.
