昆虫羽ばたき飛行の操縦性に関する分離型解法の検討

抄録

Insects have developed their high-performance maneuverability using flapping flight in the process of their evolution. In this study, a partitioned method based on our partition model for their flapping flight, which consists of the subsystems of the wings, the body and the control, is proposed to analyze their maneuverability. Here, the proposed method is applied for a maneuver, which is assumed as the perturbation from the static hovering state. In this case, a specific analysis procedure reduced from the proposed method is the one way coupling from the wing to body subsystems, i.e. the insect flapping wings are analyzed using a finite element method for the fluid-structure interaction, the resulted thrust force acts on the insect's body, and its motion is calculated using the equation of motion of a rigid body. The fundamental performance of the proposed method is demonstrated from the comparison between the present results and the actual observation with respect to the yaw, roll, and pitch as three basic modes of maneuver.
