Did you know?
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 WebMay 15, 2012 · However, a recently proposed passive stability mechanism for flapping flight, flapping counter-torque (FCT), may permit some flying animals to use a different approach to control aerial locomotion by altering the interaction of wing and body dynamics with neuromuscular inputs (Hedrick and Robinson, 2010).
WebMay 1, 2009 · We 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... 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.
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. WebFeb 24, 2010 · Free-flight body dynamics and wing kinematics were collected from recordings of continuous, low-speed, multi-wingbeat yaw turns in hawkmoths (Manduca sexta) using stereo videography.These data were used to examine the effects of rotational damping arising from interactions between the body rotation and flapping motion …
