The document describes an external flow optimization process to increase the lift to drag ratio of an aircraft wing model. Key steps include: 1) Creating a computational fluid dynamics model and defining the objective to maximize lift to drag ratio. 2) Generating design variables by deforming the wing camber and adding a winglet. 3) Using an optimizer to automatically deform the wing over 6 hours, increasing lift to drag ratio by 8% from 11.73 to 12.69.
