This study involves multi-objective optimization and aeroelastic analysis of small wind turbine blades made of date palm fibers. By employing a genetic algorithm-based optimization approach, the primary goal of this work is to design an optimal shape for domestic wind turbine applications, with a focus on twist and chord distributions over the rotor blades. For this purpose, three promising profiles (namely the airfoils: BW-3, E-216 and SG6041 obtained from our recent previous work) have been selected to undergo the optimization process, considering the minimization of starting time and blade material mass, as well as the maximization of aerodynamic efficiency as dominant objective functions. Subsequent aeroelastic analysis assesses the performance of the proposed blades, considering structural factors such as deformation, stress, and stiffness. Results indicate that while Blade-2 (based on E-216 airfoil) exhibits the highest aerodynamic efficiency, Blade-3 (based on SG6041 airfoil) provides the best structural performance, with minimal stress and deflection and superior stiffness. The optimized twist and chord distribution of Blade-3 is the most promising design for residential wind turbine applications, potentially offering a balanced compromise between aerodynamic and structural requirements.
