摘要： A vane structure for a propeller for engaging fluid and preventing cavitation or the rapid formation and collapse of low-pressure gas bubbles in a liquid. The vane structure for a propeller includes a plurality of spaced vanes that are mounted to and extend away from a hub. Each of the vanes has a leading edge, a trailing edge and an end. A lip is mounted on the end of each of the vanes for selectively engaging fluid and dispersing low-pressure gas bubbles positioned generally adjacent to the plurality of spaced vanes.
