打破“飞行魔咒”，南航科研团队创造世界纪录

Core Viewpoint - The research team led by academicians from Beijing Institute of Technology and Nanjing University of Aeronautics and Astronautics has successfully overcome the challenge of rigid-elastic coupling flutter in next-generation flying wing aircraft, achieving a world record by increasing the safe flight speed by 62.5% within structural strength limits [1][4]. Group 1: Technological Breakthroughs - The team developed a "smart anti-flutter system" that does not require structural modifications or additional weight, relying instead on the aircraft's own sensor systems to monitor flight data and adjust aerodynamic forces in real-time [2]. - A significant theoretical innovation was achieved with the development of a rigid-elastic coupling dynamic model with only four degrees of freedom, clarifying the coupling mechanisms between various flight dynamics modes [4]. - The team successfully created China's first fully independent rigid-elastic coupling flight dynamics modeling software, breaking foreign technological monopolies [4]. Group 2: Research and Development Process - The research process spanned ten years, during which the team faced numerous challenges and failures, demonstrating resilience and teamwork in harsh testing environments [2][3]. - The team conducted extensive flight tests under high-risk conditions, ultimately achieving a critical speed increase for flutter suppression [4]. Group 3: Recognition and Publication - The research findings were published in the prestigious journal "ASME Applied Mechanics Reviews," marking a significant achievement in the field of dynamics and control in China [5].
