Data from: Leading-edge vortices over swept-back wings with varying sweep geometries
Micro air vehicles are used in a myriad of applications, such as transportation and surveying. Their performance can be improved through study of wing designs and lift generation techniques including leading-edge vortices (LEVs). Observation of natural fliers, e.g., birds and bats, has shown that LE...

Micro air vehicles are used in a myriad of applications, such as transportation and surveying. Their performance can be improved through study of wing designs and lift generation techniques including leading-edge vortices (LEVs).

We hypothesize that non-linear swept-back wings generate a vortex in the leading-edge region, which can augment the lift in a similar manner to linear swept-back wings (i.e., delta wing) during gliding flight.
