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.

WebTo this end, we developed a programmable and agile autonomous free-flying robot controlled through bio-inspired motion changes of its flapping wings. Despite being 55 times the size of a fruit fly, the robot can … WebCollege of Engineering - Purdue University
WebDefinition of the wing and body coordinate systems. (A) x'y'z' coordinate system is fixed on the wing and moves with it. xyz-axes is fixed to the body. (B) Angle of attack of the wing is the... 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 … 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, …
WebNov 1, 2009 · flapping following wing damage, we estimated the damping coeffi- cient of intact and damaged flies based on a flapping-counter torque (FCT) model (see the Supplementary Materials) ( 31 ).
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 raymond evison olympiaWebthe counter torque is provided by the outside wing, e.g. the left wing in an animal rotating to the left.
