Flapping counter torque
WebBesides this, models have shown influences on flapping flight from damping of angular velocity by a flapping counter-torque, spanwise flexibility of the wing, and flapping frequency of the wing ... 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 …

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.

Coupling the overall rotation of the body with symmetric motion of the wings causes … WebWe investigated whether flapping flight has an inherent stability by analyzing the inertial and aerodynamic effects of flapping wings on body dynamics. Based on wing and body kinematics of free...
Webis flapping symmetrically, gives rise to a force asymmetry (and therefore a torque) that acts to slow the animal’s rotation (Fig. 2, C and D). We refer to this form of damping as FCT because it depends on flapping and acts counter to the direc-tion of body rotation. Below, we explore the scal-ing implications of FCT by postulating a simple WebThe counter torques generated by the wing pair due to body rotations were previously termed as flapping counter-torques (FCTs). For all three types of rotation, stroke-averaged FCTs are collinear with the rotation axes but opposite to the directions of rotation.
