Today, the installation of wind farms around the world is booming, and aerodynamic research on wind turbines is highly specialized. Using Computational Fluid Dynamics (CFD), it is possible to assess the influence of loads on the aerodynamic performance of the wind turbine. To improve its performance and reliability, a good modelling of the airflow around the turbine is very important. In this paper, the study is divided into three parts: Firstly, the aerodynamic study of the blade was carried out with ANSYS CFX. Secondly, the modal analysis in pre-stressed mode was performed to find the natural frequencies of the blade with ANSYS MECHANICAL. The last part is devoted to the study of the reliability of the wind turbine blade with FORM and SORM methods developed with a MATLAB code. Éditeur : ISTE OpenScience
