Three-dimensional flow and load characteristics of flexible revolving wings at low Reynolds number

Increasing interest in the field of micro air vehicles has stimulated research activities regarding biological flapping-wing flight. An important characteristic of biological flapping-wing flight that is not commonly taken into account in mechanical model simulations is the influence of wing flexibility. This experimental study explores the flow...

Three-dimensional flow and load characteristics of flexible revolving wings at low Reynolds number

This study explores the flow field and fluid-dynamic loads generated by revolving low-aspect-ratio flat plate wings undergoing a revolving motion starting from rest. Three wings with different degree of chordwise flexural stiffness (i.e., rigid, moderate flexibility and high flexibility) have been tested in order to investigate the influence of...
