An Overview of the Research on Flight Flutter Testing

Flutter is an unintended phenomenon due to interactions between aerodynamic forces, elasticity and inertia, which leads to unstable structural fluctuations, often leading to structural failure. Most high speed and/or flexible aircraft are highly sensitive to flutter. In this research, extended methods in the last few decades in flutter flight testing are reviewed. Similarly, structural excitation systems, measurement systems, digital processing of data and methods for extracting frequency and damping parameters are considered. Also, the practical experience in this context is mentioned and the current state of this research area is explored.
