How animals use spanwise flexibility for extreme manoeuvrability

Abstract eng:
Similar bending rules are observed on the wings and fins of animals across the entire domain of swimming and flight. The purpose of this study is to investigate why they pursue similar strategies, in terms of how profile deformation affects the growth and convection of the leading-edge vortex (LEV). To this end, three-component velocimetry measurements capturing the LEV has been conducted in order to determine how the choice of profile bending shapes can be used to control LEV strength and convection. Preliminary results suggest tip-lagging kinematics reduce LEV circulation, while tip-leading kinematics increase circulation.
