A rotor-system damage detection methodology is formulated for an articulated rotor in hover, and in forward flight. Damages are represented by changes in mass, stiffness, damping and aerodynamic properties of the rotor blade. A rotor aeroelastic analysis based on finite element discretization in space and time, and capable of modeling dissimilar blades, is used to simulate the undamagedand and the damaged rotor. Changes in rotor system behavior are identified for the selected faults and tables of rotor system diagnostics are compiled.
