WebFlapping counter-torque during a yaw maneuver.The hovering bird is engaged in down-stroke and is yawing counterclockwise about a vertical axis. Coupling the overall rotation of the body with symmetric motion of the wings causes … Flapping counter-torque is a ubiquitous passive rotational damping effect in flapping flight that arises from world frame differences in the speed of flapping wings during turns. 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 …
WebFeb 15, 2010 · A quasi-steady aerodynamic simulation of turning maneuvers with symmetrically flapping wings showed that body rotation causes a substantial aerodynamic counter-torque, known as flapping counter-torque (FCT), which acts in the opposite direction to turning. WebThis net velocity asymmetry, which arises when the animal is flapping symmetrically, gives rise to a force asymmetry (and therefore a torque) that acts to slow the animal's rotation …

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
