摘要

Measurements are reported of the velocity field andrnvortex trajectories of a finite wing of rectangular flatrnplate planform with 3% circular arc camber andrnaspect ratio 2.42. The wing is flapped at a reducedrnfrequency of 0.5 with flapping amplitude of +35.2°/-rn13.4°. The periodic velocity field is measured byrnlaser velocimetry over a grid of approximately 0.06crnspacing. Experimental data are compared to potentialrnflow models to highlight their shortcomings in thernlow-Re, highly unsteady flight regime. Preliminaryrnlift measurements are also reported.
