创造世界纪录！新技术将飞机飞行的颤振临界速度提高62.5%

Core Viewpoint - The breakthrough in addressing the issue of aeroelastic flutter in flying wing aircraft design significantly enhances flight stability and speed, marking a major advancement in aerospace technology [1][2]. Group 1: Research Breakthrough - The research team at Nanjing University of Aeronautics and Astronautics has achieved a world record by increasing the critical flutter speed by 62.5% within the structural strength limits [1]. - The team developed a four-degree-of-freedom aeroelastic coupling dynamic model, clarifying the mechanism of aeroelastic flutter and revealing the influence of sensitive parameters on flutter characteristics [1]. Group 2: Technological Innovation - The team has created a proprietary aeroelastic coupling flight mechanics modeling software, breaking foreign monopolies in this area [2]. - This technology acts as an "intelligent anti-flutter system," allowing real-time monitoring and adjustment of aerodynamic forces without altering the aircraft's original design or adding extra weight [2]. Group 3: Practical Application - The team has successfully developed a flexible flying wing layout unmanned aerial vehicle (UAV) with a span ratio exceeding 10, which has validated the increased critical flutter speed during flight tests [2]. - This technology provides crucial support for the development of China's next-generation flying wing layout aircraft [3].
