On the maintenance of an attached leading-edge vortex via model bird alula

12 Jan 2020 Linehan Thomas Mohseni Kamran

Researchers have hypothesized that the post-stall lift benefit of bird's alular feathers, or alula, stems from the maintenance of an attached leading-edge vortex (LEV) over their thin-profiled, outer hand-wing. Here, we investigate the connection between the alula and LEV attachment via flow measurements in a wind tunnel... (read more)
