The flow past low aspect ratio wings involves complex three-dimensional mechanisms due to the non-negligible influence of wing tip vortices and, in the specific case of rotating wings, due to non-negligible centrifugal and Coriolis effects. These three-dimensional mechanisms significantly modify the stall characteristics in comparison to those of quasi-two-dimensional wings and are found to play a key role in natural flyers (e.g. insects, autorotating seeds). Here, we analyze the interplay between three-dimensional mechanisms and aerodynamic performance of low aspect ratio wings and show how nature can inspire aeronautics to develop high-lift wings.
