A method for modeling unsteady transonic flows at low computational cost is presented as a first step towards fast aeroelastic calculations. The proposed approach is based on the interpolation of dynamic modes between solutions at different frequencies that are obtained either from Dynamic Mode Decomposition (DMD) of unsteady simulations or directly from Harmonic Balance (HB) simulations.
