Abstract:
Non-elliptic lift distributions were originally conceived by Prandtl as a solution for wings having optimal aerodynamic
and structural efficiency. Since 1933, many researchers have expanded on this theory to confirm that it
explicitly facilitates the trade-off between induced drag and weight, and have unveiled other potential benefits
such as proverse yaw. This theory is seen as a promising alternative to redefine the underlying principles of
conceptual wing design in the search for a step increase in efficiency. Given the recent revival of this approach,
in this paper the authors present a concise review of its theoretical basis, the developments carried out in this
area and their relevance to the future of aviation.
