Oscillating Hydrofoil Propulsion for Human-Powered Watercraft Applications [PDF]
, 2013 Unlike conventional propellers, flapping wings may generate large amplitude oscillating forces, which can make them difficult to incorporate into a craft design. This is particularly true for a single, vertically oscillating hydrofoil, as part of a surface water craft where the cyclic lift of the hydrofoil disrupts the craft stability.

NUMERICAL STUDY ON OSCILLATING HYDROFOILS FOR ENERGY EXTRACTION
Simulation results reveal that the fully prescribed system achieves a total efficiency of 38.6%, with heaving motion accounting for a heaving efficiency of 57.55% and a total average power output of 139.53 W. In contrast, the semi-passive model generates significant unsteady vertical motion—approximately three times larger in displacement—yet fails to ...

The unsteady forces on slender delta wing hydrofoils oscillating in heave
1968The investigations described herein are both experimental and theoretical. An experimental technique is described by which the models tested could be oscillated sinusoidally in heave. The apparatus used to gather the unsteady lift, drag and pitching moment data is also described.
