The Steady form of ASWING’s extended non-linear LLT is recalled and benchmarked using both experimentalrnand CFD data. A tandem configuration is used as a strong vortices interaction example with a low aspect ratiornto present the benefit of such software to predict lift and drag coefficients of multiple lifting surfaces
