The final shape for the Concorde’s wing was an ogee delta, and when viewed closely is a complex arrangement, including a downturned leading edge lip, as well as the reflexed leading edge line seen in plan view.

But it wasn’t the only option, as seen here, in this row of model shapes considered by the designers, the final, settled example at the end. ‘Strictly’ good engineering design, yet a strange primal beauty in them.
