This paper introduces a method that utilizes the response surface methodology into genetic algorithm to solve the aeronautical nonlinear optimization problem. This method is used in a transonic flutter optimization of a horizontal tail and the analysis result shows that this method can be used in aeronautical nonlinear multidisciplinary optimization.
