Short summary
High-fidelity fluid–structure-coupled simulations of the IEA 15 MW rotor under storm and yaw misalignment shows that certain misalignments trigger strong edgewise vibrations. Growth surges when effective power turns positive near −35° and fades near −43° yaw. Single-blade analysis finds lock-in at −37° with large tip motion and stability at −60° due to off-resonant Strouhal shedding. It is concluded that aeroelastic response is inflow specific, and operational mitigation strategies are needed.
