J0205-2-2 Property of flapping flight of Anomala japonica

Abstract

Recently, the unsteady aerodynamics of flitting flights for birds and insects has attracted the interest of many researchers. They take aerodynamics property of flapping flight as research for a bat, a bird, a dragonfly, a mosquito, a bee and a butterfly, etc. The present work is aim to investigate the flapping flight of small beetle such as Anomala japonica. The flapping motion and flow field of wing are visualized with high speed video recording, dynamic PIV and CFD. Measured flapping frequency is about 71Hz. Anomala japonica has six phases of wing motions, feathering, clap and filing, lead-lug, upstroke and downstroke processes.
