This work is concerned with systematically investigating different data-driven techniques for identifying CFD-based reduced-order models of the unsteady aerodynamics necessary to formulate the aerodynamic operator for transonic aeroelastic stability analyses. Focus is given to the relative merits and costs of the different methods in predicting the flutter onset.
