To develop an eigenmode or proper orthogonal decomposition POD modal representation of unsteady aerodynamic forces on oscillating flexible airfoils and wings and thereby reduce the size and cost of mathematical models for such forces by several orders of magnitude. Building on earlier work for two-dimensional inviscid flows, we seek to extend our models to. three-dimensional flows with viscous effects included. Also a novel form of the harmonic balance HB method had been developed for determining limit cycle oscillations LCO of aeroelastic systems.
