Aeroelastic analysis and flutter control of wings and panels: A review
International Journal of Mechanical System Dynamics, 2021 Flutter is a self‐excited vibration under the interaction of the inertial force, aerodynamic force, and elastic force of the structure. After the flutter occurs, the aircraft structures will exhibit limit cycle oscillation, which will cause catastrophic ...
