  • S111064 Fabrication of Artificial Wing with Deformation and Vibration Characteristics Like Dragonfly Wing

抄録

The dragonfly wing is passively deformed under flapping, simultaneously has the strength to withstand high flapping frequency. These characteristics of deformation and vibration of the wing is important for dragonfly flight. However, the effect of that on a dragonfly flight has not been well understood. In this study, for the purpose of investigating an artificial wing suitable for flapping micro air vehicle, we measured natural frequency and deformation in flapping of dragonfly wing and fabricated the artificial wing based on the results of that. From the results of measurement, the dragonfly wing has the high natural frequency of 120Hz. Moreover, although base-side of the wing is hardly deformed, the tip-side of the wing is greatly deformed because of the torsional deformation from the nodus of dragonfly wing. Then, we fabricated the deformable artificial wing which deformation is the same as dragonfly wing and measured aerodynamic force and power consumption under flapping. As a result, the power efficiency of aerodynamic force when using the deformable artificial wing is 5 times greater than the power efficiency when using an undeformable wing.
