Abstract
The overall objective of this work is to develop a general-purpose CFD-based, shape optimization tool for robust and efficient aerodynamic shape optimization. Shape optimization is a technology where design optimization algorithms are coupled with geometry/shape deformation tools and engineering analysis codes such as computational fluid dynamics and structural analysis. The optimization algorithms search for value of arbitrary shape deformation design variables to improve the object function (i.e. maximize lift, minimize drag, maximize lift-to-drag, etc.) While satisfying design constraints (i.e. limits on stability, mass properties, etc.). the shape optimization tool can be used to find optimal designs for aerodynamic shapes of aircraft, missiles, submarines, etc. A graphical user interface will be developed To allow the user to read in a CFD input file, define an arbitrary shape deformation control volume, pose the desired shape optimization problem to be solved, perform the optimization of the aerodynamic shape, and visualize the results via animation and post processing. Advanced arbitrary shape deformation tools will be developed. Powerful and efficient optimization methodologies will be employed. Data translators will allow practically any CFD code to be incorporated with this tool.
