IAC–06–A3.P.3.07 ROBUST AERODYNAMIC AIRFOIL DESIGN OPTIMIZATION AGAINST WIND VARIATIONS FOR MARS EXPLORATORY AIRPLANE

Robust aerodynamic airfoil design optimizations of Mars exploratory airplane against wind variations have been carried out by using DFMOSS coupled with the CFD simula-tion. The present robust optimizations successfully found the airfoil designs with robust aerodynamic performances against wind variations. Obtained airfoil design information about the optimality and the robustness of aerodynamic performances indicated that an airfoil with smaller camber can improve the robustness in lift to drag ratio against the variation of flight Mach number, and an airfoil with larger curvature near the shock wave location can improve the robustness in pitching moment against the variation of flight Mach number
