An advanced model of the nonlinear unsteady aerodynamic characteristics is presented based on Goman’s state-space model. The progressive state-space description of Goman’s model is improved and the nonlinearities of the attack angular rate and the flow separation position are considered. The proposed modelling approach is verified by the wind tunnel data.
