Reduced-Order Aeroservoelastic Model with an Unsteady Aerodynamic Eigen Formulation

Abstract

The purpose of this study is to construct a new aeroservoelastic model using a two dimensional, incompressible aerodynamic eigenformulation in the continuous time domain. The work is based on the discrete time domain eigen model by Hall. To obtain a reduced order model with real coefficients, a modal decomposition technique that transforms the aerodynamic matrix into a canonical modal form is introduced. A simple typical section model with two strain actuated control inputs is used for an aeroservoelastic design
