Core Viewpoint - The breakthrough in suppressing the aeroelastic coupling flutter in flying wing aircraft design marks a significant advancement in aviation technology, enhancing flight stability and speed without compromising structural integrity [3][10]. Group 1: Research Achievements - The research team from Nanjing University of Aeronautics and Astronautics has successfully increased the flutter critical speed by 62.5%, setting a world record in this field [3][10]. - The study, published in the international journal "Applied Mechanics Reviews," is the only paper from China's dynamics and control scholars in the past 20 years to be featured in this journal [5]. Group 2: Technical Innovations - The team developed a four-degree-of-freedom aeroelastic coupling dynamic model, which clarified the coupling mechanisms between various flight dynamics modes, thus revealing the influence of sensitive parameters on flutter characteristics [10]. - They created China's first fully independent intellectual property software for aeroelastic coupling flight dynamics modeling, overcoming foreign technology monopolies [10]. Group 3: Practical Applications - The newly developed technology acts like an "intelligent anti-flutter system," utilizing sensors to monitor flight data and adjust aerodynamic forces in real-time without altering the aircraft's original design [11]. - The successful flight tests of a flexible flying wing layout unmanned aerial vehicle (UAV) with a span ratio exceeding 10 validate the effectiveness of the new flutter suppression technology [11].
