Comparative Study of 3D Wing Drag Minimization by Different Optimization Techniques

The main goal of this paper is to document a comparative studyof different CFD based optimization techniques applied to the so-lution of a 3D wing drag minimization problem. To achieve thisobjective, three optimization tools were used: SYN107 (Intel-ligent Aerodynamics Int’l), MDOPT (The Boeing Company) andOPTIMAS (Israel Aerospace Industries). The first tool employsgradient-based search techniques using the ”continuous” adjointequation, the second one is a response-surface method, while thelast one uses a floating-point Genetic Algorithm as its search en-gine. As the starting geometry, the public domain DPW-W1 wing(a test-case for the 3
