All else being equal, this results in an aerodynamic `counter-torque' that acts counter to the direction of turn to stabilise the ...
WebDec 15, 2011 · Flapping counter torque and similar flapping-related damping effects add a new dimension to scenarios describing the evolution of powered flight in animals, … Webthe counter torque is provided by the outside wing, e.g. the left wing in an animal rotating to the left. In the upstroke phase, the counter torque is provided by the inside wing (Fig. 2). The effect described above can be combined with equations for blade-element models of flapping flight – simplified mathematical
WebWe further developed the dynamic models of flapping flight in hover, performed stability analysis and flight control. ( TRO, DSCC, ACC, and JRM papers).

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).

This is due to smaller upstroke wing pitch angle asymmetries as well as increased upstroke flapping counter-torque from left-right differences in global reference frame wing velocity about the moth's roll axis. tti bom toolFlapping 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 … phoenix counseling and wellness llcWeb(Thanks to the Flapping Counter Torque), this results in a slow, steady yaw rotation.
