Robust Airfoil Optimization Using Maximum Expected Value and Expected Maximum Value Approaches
Robust Airfoil Optimization Maximum Expected Value Expected Maximum Value Approaches
2015/7/3
Deterministic engineering design often leads to unexpected or physically unrealizable results. This is due to the fact that deterministic design is not able to capture the effects of even slight natur...
