The aeroelastic response and stability of hingeless rotor blades in hover are investigated using both refined aerodynamic and structural models. Three-dimensional aerodynamic model based on the unsteady vortex lattice method with a prescribed wake geometry is applied to evaluate the aerodynamic loads. Finite elements based on the large deflection beam theory are used for the blade structural model. It is found that the three-dimensional aerodynamic tip-relief and unsteady wake dynamics effects, not predicted in the two-dimensional strip theory, play an important role in the hingeless rotor aeroelastic analysis in hover.
