This paper presents the application of higher order dynamic mode decomposition (HODMD) to flutter flight test data in order to extract aircraft frequencies and damping. The method is an extension of DMD, a method typically used to extract flow patterns and frequencies from unsteady fluid dynamics measurements or simulations. In the fluid dynamics field, it has been shown to be able to extract modes, frequencies and damping from very noisy and large signals, in a robust and efficient way, with reduced manual interaction.
