Abstract

Optimal ways of locomotion in paddling are analyzed theoretically and verified by observing locomotion of webbed or broad feet of turtles swimming in a water channel. In the optimal locomotion, a paddle is placed perpendicular to a moving direction of turtles. And a direction of paddling motion may vary according to an angle of attack of the paddle whereas lift-to-drag ratio is the highest at maximum efficiency and fluid dynamic coefficient CR(=√CL2+CD2) is maximum at maximum thrust.
