| Abstract: | A rotor/nacelle/wing system of tilt-rotor is a typical coupled rigid flexible body.An aeroelastic stability model for the tilt-rotor aircraft on airplane mode and the helicopter mode is used to study the influences of rotor and wing dynamics parameters on the tilt-rotor aeroelastic stability.Results of rotor and wing dynamics parameter effects at the whirl flutter speed in cruise and mode damping in hover are provided.The study is valuable for the tilt-rotor dynamics design. |

| Keywords: | tilt-rotor aircraft dynamics aeroelastic stability whirl flutter mode damping |
