Simultaneous aerodynamic analysis and design optimization (SAADO) for a 3-D rigid wing
Clyde R. Gumbert, Gene Hou, Perry A. Newman · 14th Computational Fluid Dynamics Conference · 1999
The formulation and implementation of an optimization method called Simultaneous Aerodynamic Analysis and Design Optimization (SAADO) is presented 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 flow analysis and sensitivity analysis tools. Results for this small problem show that the method reaches the same local optimum as conventional optimization methods and does so in about half the computational time.
