The aim of this investigation is to develop a micro air vehicle (MAV) for rescue inquiry devices. In order to inquire the disaster area, MAV requires hovering flight. To understand the hovering flight of insect, flow pattern of a flapping machine was visualized by using the PFV measurement and numerical simulation. PIV measurements were carried out with a sinusoidal flapping machine which was 10 times expanding model of real insects. The experimental result showed a leading-edge vortex can be captured around a flapping airfoil. The numerical results were good agreement with experimental ones. The lifting force of sinusoidal flapping is not enough to lift an insect itself. However, numerical result showed flapping motion with feathering generate large lifting force, it is enough to lift the insect. Therefore, feathering motion is key technology for development hovering flight MAV.
