摘要：

Aeroelastic analysis of a full scale composite wind turbine blade is investigated using its 3D model. Aerodynamic loading is determined using modified Blade Element Momentum theory and Computational Fluid Dynamics method is employed for verification. 3D finite element model of the blade is built and then Fluid-Structure Interaction iterative approach is constructed to investigate the aeroelastic behavior. Influence of deformation on power performance is determined implying on a reduction in output power. Susceptibility of dynamic instability is investigated and it is found out at high wind speed that the blade may experience instability. (C) 2016 Elsevier Ltd. All rights reserved.
