In this study, an optimization process for the stiffness of a composite helicopter blade had been done with respect to the minimum weight. A nasa0015 airfoil with its original geometries had been considered, the angles and directions had been analyzed, the elimination analyses had been done to solve the problem and the optimization process had been made in order to have the maximum stiffness by the use of the ABAQUS and SOLIDWORKS M.P. the best and worst stack ply had been specified with respect to the blades stiffness
