A wing with a wing span (b) has a main part (1), which has a substantially closed surface with respect to the flow (v) and is provided at its free end with an end section in the form of a wing grid. The wing grid has at least two parallel-staggered winglets (2). The wing grid as part of the wing span (b) takes over the intended profile circulation at the attachment point to the main part and subdivides that circulation approximately uniformly over the winglets. The same lift is produced in the end section with the at least two winglets. Thus, for the win...
