Aeroelastic Stability of Wind Turbine Blades Based on Beddoes-Leishman Model

Aeroelastic stability of wind turbine blade sections has been studied in detail by means of eigenvalue analysis subjected to flap/lead-lag motion based on Beddoes-Leishman model. The paper described different damping ratio influencing for aeroelastic stability by using state-space approach. The analysis results are confirmed by another approach of system response. The point to be emphasized here is that the eigenvalue methods of Beddoes-Leishman theory play an important role in analyzing stability for wind turbine blades.
