Webof flapping wing flies [9]. In this study, we first derived a stroke-averaged 6-DOF model for flapping-wing insects based on the flapping counter-torque [6, 7, 9] and flapping counter-force (FCF) models. Then we studied the near-hover attitude dynamics and control of a model insect (mimicking the morphology WebThese data were used to examine the effects of rotational damping arising from interactions between the body rotation and flapping motion (flapping counter-torque, FCT) on continuous turning. The moths were found to accelerate during downstroke, then decelerate during upstroke by an amount consistent with FCT damping.
