Shape sensing of NREL 5 MW offshore wind turbine blade using iFEM methodology
Ocean Engineering, 2023 In this study, the shape sensing of a blade of the NREL 5MW offshore wind turbine is presented by using the inverse Finite Element Method (iFEM) under real loading conditions. Among the applied forces, the aerodynamic forces are calculated based on the Blade Element Momentum Theory (BEMT).
