Abstract
The formulation and implementation of a multidisciplinary optimization method called Simultaneous Aerodynamic and Structural Design Optimization (SASDO) is presented and applied to a simple, isolated, 3-D wing in inviscid flow. The method aims to reduce the computational expense incurred in performing shape and sizing optimization using existing state-of-the-art Computational Fluid Dynamics (CFD) flow analysis, FEM structural analysis and sensitivity analysis tools. Results show that the method finds the same local optimum as a conventional optimization method with as much as 50% reduction in the computational cost and without significant modifications to the analysis tools.
