Keywords: aeroelasticity, aerodynamics, helicopter rotor, vibration

An aeroelastic method has been developed that integrates a CFD solver Cobalt and a multibody dynamics analysis tool DYMORE. The aeroelastic method is first applied to the H-34 helicopter rotor which has been widely used for rotor model validations. The model is then applied to the Bell 412 helicopter rotor.
