Abstract [en]

The paper describes the comparative study of two optimization frameworks on Case III, twist optimization for induced-drag minimization. Both frameworks use gradient-based optimizers. With different flow solvers and other algorithmic differences they find different optimized shapes, all with the CD,i reduced by around 1 count.
