Robust Aerodynamic Design of Mars Exploratory Airplane Wing: with a New Optimization Method

A new robust design optimization approach "design for multi-objective six sigma (DFMOSS)" has been developed, and aerodynamic design optimizations of Mars exploratory airplane wing considering the effects of wind variations were carried out by using the DFMOSS coupled with the computational fluid dynamics (CFD) simulation. The present optimizations successfully revealed detailed trade-off information between the optimality and the robustness of aerodynamic performance more efficiently than conventional robust optimization approaches. In addition, useful guides to more reliable design of Mars exploratory airplane wing and more reliable Mars exploratory missions using the airplanes were provided by discussing the obtained trade-off information from an aerodynamic viewpoint.
