• E-1-1 Relationship between Deformation of Wings and Feathering Motion on Dragonfly Flight

抄録

Dragonfly wing is passively deformed in the tip side from nodus flapping flight. Wing deformation is thought to correspond to feathering motion. However, dragonfly perform a feathering motion activiely. In this study, the effect of passive deformation of the wing on aerodynamic force in flapping flight with feathering motions was investigated using fluid-structure interaction analysis. In this analysis, nodus wing models, which can deform passively, and rigid wing model, which cannot deform, are used. Feathering angle is three typse: 0, 20, 40 deg. As a result, when the feathering angle is 20 deg or less, the nodus wings reduce drag force by deformation of Wing during downstroke. However, when the feathering anble is 20 deg or more, overlarge deformation of wing decreases lift force. Therefore, the sing with the appropriate level of flexibility can reduce drag force without wasting energy of feathering motion.
