Numerical and Experimental Study of a Bio-Inspired Flapping Wing with Increasing Twist Angle Along the Wingspan

Machines
Inspired by the movements of sea turtle forelimbs, this study presents a bio-inspired underwater flapping wing with three degrees of freedom. This flapping wing mechanism can more accurately simulate the rotational motion of a sea turtle’s forelimbs to ...
