Fluid-Structure Interaction (FSI) is a critical problem in the wind turbine operations. Reliable FSI computations is a necessary crucial step towards achieving a safe efficient and prolonged operational lifetime for wind turbines. In this work, FSI computations in being held on the GE 1.5XLE wind turbine blade as a preliminary step in the developing of a reliable FSI model for wind turbine simulations. The fully resolved turbine blades are simulated in turbulent flow (k-ω SST model) with inlet velocity 12 m/s and turbine angular velocity of 2.22 rad/s. The aerodynamic loadings are firstly computed using Ansys FLUENT. The pressure and velocity distributions are then passed on to Ansys Mechanical to get the resultant structural deformations and stresses. The aeroelastic coupling effects from the CFD solver are then verified against the analytical solution showing a very good agreement.
