Nonlinear Flutter Analysis of Labyrinth Seals
Journal of Turbomachinery, 2022 Abstract A simple nonlinear model to describe labyrinth seal flutter has been developed to assess the aeromechanic stability of straight-through labyrinth seals subjected to large gap variations. The model solves the one-dimensional integral mass, momentum, and energy equations of the seal for a prescribed motion numerically until a ...

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 ...
