... of mechanical elements with distributed mass, damping, and stiffness characteristics. The behavior of the structural components of the turbine is approximated as that of their dominant modes and the wind-blade aerodynamic interaction is modeled using the Blade Element Momentum (BEM) theory. The modeling...
