This paper concerns the effect of steady state deflection of a wind turbine blade on its aeroelastic stability. Modern wind turbines have long slender blades where the deflection can be considerable. Today, most aeroelastic stability tools do not take finite blade deflection into account when computing the stability of the turbine. In this study an aeroelastic model of a turbine blade, which include blade deflections, is developed and used for analyzing the effect of steady state blade deflections on the aeroelastic stability. It is found that the flutter speed for the RWT 63 m blade decrease when the steady state blade deflection is included in the analysis.
