520 _aThe ventis 20 - 100WT turbine is operated in wind farms in hurghada. The blades were locally manufactured because of the multiple failures and lack of spare parts at the AOI. Here in this thesis, the re - designed blades are aerodynamically and structurally examined. First, the steady and unsteady aerodynamic loads are computed using BEM theory. The structural properties of the 10m composite blade are then obtained from NREL dedicated HAWT software PreComp. The steady loads are computed using NREL software and compared to a FEM, and agree reasonably well. The dynamic loads are then analyzed to determine the fatigue life and that the blades operating at frequencies other than the resonant modes. The fatigue analysis suggests that the re -designed blades have a short life about (70 month at operating RPM). Furthermore, results from an environmental study suggest that the blades life will be shorter about (52 month). In future plan we will test experimentally the manufactured blade locally to meet the design constraints requirements and try to optimize it and find a solution for isolating the material used from the environmental effect
