Reliability of aerodynamic analysis using a moment method

In this study, a reliability analysis was performed for the aerodynamic analysis. Among various reliability analysis methods, the moment method was used and the results were compared with other methods. The reliability of aerodynamic analysis of a 2D airfoil, a 3D wing and a wing body configuration were considered. In the case of 2D airfoil, the reliability was computed by parameterising an airfoil shape using the PARSEC function and considering uncertainties of its shape. In the case of 3D wing and wing body configuration, it was computed by considering uncertainties of flow conditions.
