PERFORMANCE ASSESSMENT OF PROPELLER BOSS CAP FIN TYPE DEVICE

A blade arrangement is presented consisting of a set of vanes attached to the rotating hub of the propeller. These vanes are located aft of the propeller and rotate with it. The small vanes are designed to reduce the swirl placed in the slipstream by the action of the propeller. It has been determined that the strength of the hub vortex is reduced owing to this arrangement, resulting in a propeller of higher efficiency. This efficiency gain has been verified by recordings from a relatively large number of ships fitted with the device.
