In this study a gradient-based aerodynamic shape optimization framework based on SU2 software, Class Shape Transformation (CST) and PARametric SECtion (PARSEC) methodologies is developed. Turbulent flow and adjoint solutions are computed with the SU2 software suit. The grid sensitivities obtained for the objective function are projected onto the CST and the PARSEC parameters defining the sectional airfoil profiles. The gradient projection is implemented by means of algorithmic differentiation of the python codes developed. The DAKOTA toolbox is employed to drive the gradient-based optimization process. The framework developed is first validated against the well known AIAA Aerodynamic Design Optimization Discussion Group (ADODG) optimization test cases. A close-coupled wing-tail configuration is then multi-point optimized for trim constrained transonic and supersonic drag minimization.
