Abstract

The instantaneous velocity fields are measured using particle image velocimetry (PIV) in the near-wake region of a pair of the side wings of a flapping wing Micro Air Vehicle (MAV) designed at Wright State University. A high speed camera is used to identify the phases of the flapping motion of the wings. Three dimensional topologies and the time evolution of both velocity fields and vortical structures are studied. The results also indicates that in order for the ongoing CFD efforts to be successful for providing insights to improve future MAV designs, the flow fields and wing structures need to be coupled.
