Resumo


The airfoil aerodynamic design (AAD) is a challenge problem in aerodynamic engineering and optimization. In the AAD, the goal is to calculate an optimal airfoil shape that maximizes the lift-drag ratio, where lift and drag are forces that interact between themselves. In this study we use the Parametric Section (PARSEC) method that is a linear combination of shape functions describing the airfoil shape [1]. In general, the optimizer techniques seek to calculate the parameters of PARSEC that improves lift-drag ratio. [...]
