Abstract

This paper presents a reduced-order-modeling approach for nonlinear aeroelastic systems utilizing the pruned Volterra series. This approach is used to approximate the flutter boundary and LCO amplitudes of the NACA 0012 benchmark model. Pruned Volterra series reduced-order-models up to third-order are identified and compared against experimental and harmonic balance results. Very favorable accuracies are attained for the specific transonic Mach numbers tested. The computational savings associated with the pruned Volterra series are demonstrated to be several orders-of-magnitude.
