昆虫羽ばたき時における非定常流体力計測

Abstract

Studies of flying insect have focused on low Reynolds number effect for biofluid behavior in unsteady regime. The research of atmospheric flight properties is of interest to explore biofluid mechanism by which process of the unsteady forces，wake and vortex the unsteady motions interact with flapping wing. In the present work，to simultaneous measuring of unsteady aerodynamic forces and flapping motion for flapping small beetle with sampling frequency 10 kHz. The live small beetle generated horizontal force by upstroke and feathering at T.D.C,while that generated maximum vertical force at mid-downstroke.
