Numerical study of a sinusoidal transverse propeller

Thrust scaling for a large-amplitude heaving and pitching foil with application to cycloidal propulsion

“…They are very efficient when maneuverability is required and are hence frequently used for the propulsion of tugs and ferries, for instance. A cross-flow propeller has recently been subject of experimental investigations at the Naval Academy Research Institute (IRENav) in France, where such a device has been designed, the pitching motions being controlled electrically by servo-motors enslaved by the main motor ( [42]), numerical simulations having been performed for this configuration too [49]. The device with three foils is sketched in figure 11, where the solid foils' contours are at their positions at t 0 when foil labeled 1 has the highest pitching amplitude α 0 .…”

An experimental blade-controlled platform for the design of smart cross-flow propeller

“…Recent studies [9,15] has implemented more complex models to continue to estimate as well as possible cycloidal propeller performance. Lastly improvements on modern CFD solvers are accurate validation resources and a new interesting area of work for optimization purpose [2,10,11,17].…”
