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).

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 … WebApr 30, 2024 · Flapping counter force (FCF) and Flapping counter torque (FCT), which are proportional to body velocity and wing beat frequency, have been proposed to represent flapping aerodynamic counterparts [12].
