Scaling laws for the thrust production of flexible pitching panels
TL;DR: In this article, the role of flexibility and aspect ratio in bio-inspired aquatic propulsion was investigated and shown that flexible panels can give a significant amplification of thrust production of and propulsive efficiency of when compared to rigid panels.

Thrust production and wake structure of a batoid-inspired oscillating fin.
Richard P. Clark,Alexander Smits +1 more
TL;DR: Experiments are reported on the hydrodynamic performance of a flexible fin, and a vortex model of the wake near zero net thrust is suggested and an optimal oscillatory gait is identified.
Hydrodynamic wake resonance as an underlying principle of efficient unsteady propulsion
TL;DR: In this paper, a linear spatial stability analysis is performed on the velocity profiles measured in the wake of an actively flexible robotic elliptical fin to find the frequency of maximum spatial growth, that is, the hydrodynamic resonant frequency of the time-averaged jet.

Flowfield measurements in the wake of a robotic lamprey
TL;DR: Experiments on the hydrodynamics of a swimming robotic lamprey under conditions of steady swimming and where the thrust exceeds the drag suggest that the major part of the thrust is produced at or close to the end of the tail.
Linear instability mechanisms leading to optimally efficient locomotion with flexible propulsors
TL;DR: In this article, the authors present the linear stability analysis of experimental measurements obtained from unsteady flexible pitching panels and establish the connections among the wake dynamics, propulsor dynamics, and Froude efficiency in flexible unstairedy propulsion systems.
