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.en© The Authors.Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Non-elliptic lift distributionswing designaero-structural efficiencyinduced dragproverse yawConference paper10.57996/cran.ceres-1322
