  • Anti-cavitation rudder blade
    Patent number: 4510879
    Abstract: A rudder blade means of the type designed to reduce the drag produced by rudder blades of conventional design. The novel design, having utility in any vessel that travels through a fluid medium and incorporates a substantially vertically aligned chamber formed internally of the rudder body. The chamber has a narrow, slot-like portion that is in open communication with the trailing edge of the rudder body, and an enlarged, bore-like portion remote from said trailing edge but in open communication with the innermost portion of said slot-like portion. In applications where the rudder body is mounted to a sea-going vessel, and wherein such rudder body has a submerged portion and an un-submerged portion, water enters the chamber, in a counterswirling pattern, through the slot-like portion, and is driven upwardly, by water pressure, through the bore-like portion and is expelled above the water line through the uppermost region of said slot-like portion of such chamber.
