A parametric study is carried out to optimize the design of a ducted rotor system. Computational Fluid Dynamics simulations were conducted for several designs to generate system performance characteristics data to develop surrogate models. Verfication of the accuracy of the surrogate models in representing the system performance was conducted and thereafter the surrogate models were used to investigate the design space to determine the optimum design. The study showed that the surrogate model approach is able to predict the performance within 3% of the computed data.
