Abstract

Manta rays propel themselves by combining oscillating and undulating motions of flexible surfaces. We describe two experiments to study the effects of excitation and flexibility on the wake flowfield: experiments on undulating and flapping three-dimensional fins of elliptical planform, and experiments on pitching two-dimensional panels of rectangular planform with varying flexibility. To interpret the results on thrust and efficiency, we propose scalings for aspect ratio and flexibility, and develop a stability analysis called wake resonance theory. Here we focus on the insights provided by wake resonance theory.
