Study of flapping using self-excited vibration of insect-size flying object

Abstract

Recent years, small-sized flying objects are expected to be utilized for observation in narrow places such as inside of ducts. We focused on bees with superior flight performance among small insects and designed an insect-size flying object with a flapping mechanism. We also analyzed the generated lift force when wings flapped. From the simulation results, we found that it is important to generate a large vortex at the edge of the wing film in order to obtain a large lift force.
