ABSTRACT:
Apparatus for reducing cavitation erosion is disclosed which includes ducts and openings (30, 32, 34, 40) for discharging a stream of gas positioned upstream of and adjacent to a propeller (11), in a direction perpendicular to the oncoming flow and at a lateral position relative to the propeller rotation axis.
