The aerodynamic performance of a wing mounting a simple unconventional box winglet are analyzed in detail by CFD simulations. The decomposition of the computed drag in its irreversible (viscous) and reversible (lift-induced) components by a far field drag breakdown method allows for the determination of the span efficiency, not a trivial task in the case of viscous flow. The aerodynamic performance are compared with the ones obtained in case of a simple standard winglet and without any tip appendices.
