Aeroelastic analysis and flutter control of wings and panels: A review

open access: yesInternational 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 ...

FLUTTER ANALYSIS OF BLISKS WITH FRICTION RING DAMPERS [PDF]

open access: yesProceedings of Global Power & Propulsion Society, 2022
Aeroelastic flutter is a phenomenon when blades experience an aeroelastic selfexcitation from the surrounding air resulting in the full destruction of aeroengines. It poses a big challenge for aeroengine bladeddisks design, especially for integrally bladeddisks (blisks).
