Title: Simultaneous Aerodynamic and Structural Analysis and Design Optimization (SASDO) for a 3-D Wing
Abstract: The formulation and implementation of an optimization method called Simultaneous Aerodynamic Analysis and Design Optimization (SAADO) is extended to multidisciplinary analysis - in this case, static aeroelastic analysis -, extended to include structural sizing design variables as well as shape design variables, named Simultaneous Aerodynamic and Structural Design Optimization (SASDO), and applied to a simple 3D wing problem. The method aims to reduce the computational expense incurred in performing shape optimization using state-of-the-art CFD ow analysis, FEM analysis and sensitivity analysis tools. Results for this small problem show that the method reaches the same local optimum as a conventional optimization and can show significant reduction in the computational cost.
