Forward sweep - A favorable concept for a laminar flow wing

The application of laminar flow on swept wings is authoritatively limited at high Reynolds numbers by a sweep angle where crossflow instability and attachment line transition lead to fully turbulent boundary layers on the wing. For a laminar flow wing, the reduction in sweep in the case of a forward swept wing leads to a more stable laminar boundary layer concerning transition because of crossflow instability and attachment line transition. Thus, with this concept, a laminar forward swept wing can be realized more easily than a comparable swept back wing
