Title: Transonic turbulent airfoil design optimization with automatic differentiation in incremental iterative forms
Abstract: The primary effort in this study is to develop a practical approach for incorporating a validated computational fluid dynamics (CFD) code into an aerodynamic design optimization procedure with minimal code modification. The approach relies on the automatic differentiation tool ADTFOR to generate the grid sensitivities and derivative terms required by the incremental iterative method for aerodynamic sensitivity analysis. Transonic turbulent airfoil design optimization, based on the Navier-Stokes equations, is chosen as a sample problem to facilitate discussion of the code implementation procedure and the factors that affect the computational efficiency of aerodynamic design optimization.
