Increasing cost of energy, and environmental concerns are currently forcing many nations around the world to develop diverse sources of clean, renewable energy as alternative to none-renewable fossil fuel driven energy systems. One of the clean energy alternatives that is widely explored due to high reliability is wind turbine energy systems. For optimized design in these systems, stress analysis and deformation of turbine blades are highly essential components that must be considered in the design phase due to significant influence on reliability, performance and longevity of the system. The study focused on the design of a turbine blade to improve on existing turbine blade by performance analysis using Inventor professional software for the Finite Element Analysis (FEA). The design, and performance analysis was based on a 1kva small-scale horizontal axis wind turbine blade prototype which can be scaled up based on the design specification and material performance criteria. The mechanical strength of the blade was validated using FEA by comparing three blade materials made out of Thermoplastic resin, Aluminum Alloy, and Titanium Alloy. Based on the geometrical parameters of the blades, the 3D-dimension model of blade airfoil was imported in Autodesk inventor professional software for analysis. The blade aerodynamic features, Von mises stress, mass density, and displacement characteristics are key features observed. From the outcome of the displacement result of the blades tested, the highest displacement occurred in the blade tip for all materials tested during spinning at various ideal safe speeds in line with the prototype size and the von mises stress concentration occurred in the blade center. The achieved result shows conformance with safety displacement of wind turbine as the blade design geometry was being altered until an optimal geometry was achieved. For future studies, the structural strength of the materials tested on a comparative basis can be explored by comparing other composites, and validation of results using diverse environmental conditions.
