Pseudospectral Continuation for Aeroelastic Stability Analysis [PDF]
Journal of Vibration and Acoustics, 2022 AbstractThis technical note is concerned with aeroelastic flutter problems: the analysis of aeroelastic systems undergoing airspeed-dependent dynamic instability. Existing continuation methods for parametric stability analysis are based on marching along an airspeed parameter until the flutter point is found—an approach that may waste computational ...

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 ...

Quantitative Aeroelastic Stability Prediction of Wings Exhibiting Nonlinear Restoring Forces
Journal of Mathematical Sciences and Modelling, 2023 In engineering practice, eigen-solution is used to assess the stability of linear dynamical systems. However, the linearity assumption in dynamical systems sometimes implies simplifications, particularly when strong nonlinearities exist.

Aeroelastic vibration analysis of a 1.5 stage compressor
Propulsion and Power Research, 2020 Aeroelastic vibration problems are commonly found in modern compressors operating in off-design conditions. Large amplitude vibration could lead to high cycle fatigue (HCF) of blade and usually occurs in front stages of axial compressors.
