Flapping counter torque
WebFeb 10, 2024 · This could be done to delay flapping counter-torque , which will slow down the initial body rotation in the first half of the recovery behaviour. The inverse dynamic model showed a ramp-up of body torque starting at 37.8 ± 9 ms (n = 8), suggesting that some torques were generated before flapping occurred. Because the correlation between ... Webknown as flapping counter-torque (FCT), insect flight subjects to an inherent damping of angular velocity about roll, pitch [6] and yaw [7-9] axes of rotation. Remarkably, the …

During a turns, flapping that is symmetrical (in velocity and speed) in the body frame of the animal is not symmetrical (in velocity or speed) in the lab frame. During such turns, the wings travel at different speeds (despite no change to local velocity from …
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.
