... integration with lifting line (SILL) method described in (Persson et al., 2019). The method is based on Prandt lifting line theory and the assumption of an elliptical lift distribution. An important feature of the SILL method is that 2D RANS CFD is used to obtain tabulated lift and drag coefficients...
