   Abstract:
   This paper presents a new method for the state space modeling of aeroelastic panels subject to linearized potential flow aerodynamic loading. This is accomplished by approximating the aerodynamic generalized forces on the panel with discrete, infinite impulse response (IIR) filters. These filters are coupled to the in vacuo panel dynamic system as feedback, thus, creating a coupled, aeroelastic system. The accuracy of the model is established by comparing the panel flutter boundaries of the approximate system with those found in past studies.
