The AIAA Aerodynamic Design Optimization Discussion Group (ADODG) was formed to address the need for aerodynamic design optimization benchmarks that could be used to compare methods between different researchers. There are 6 benchmark cases.

The objective of this problem is to minimize the drag of a NACA 0012 airfoil in transonic, inviscid flow.

The objective of this problem is to minimize the drag of an RAE 2822 airfoil in transonic, turbulent flow.

The objective of this problem is to minimize the drag of a rectangular wing with NACA 0012 cross-sections in subsonic, inviscid flow.

This page contains the optimized geometry and grid file of the Common Research Model (CRM) wing optimization case for AIAA Aerodynamic Design Optimization Discussion Group (ADODG). Please see the paper 1 for more information.

This problem takes the wing from Problem 3 and increases the number of design variables to allow a very large degree of flexibility in the parametrization. The problem description is available in the attachments at the bottom of this page.
