SHIP PROPELLER BLADE

SHIP PROPELLER BLADE

This invention is designed to reduce the danger of corrosion damage to a propeller, which is caused by the cavitation of fluid when a ship moves. A cavitation production part(17) on the suction side(11) and a curved part(19) on the blade are located at the same distance from the propeller axis(7). T...

Zusammenfassung:This invention is designed to reduce the danger of corrosion damage to a propeller, which is caused by the cavitation of fluid when a ship moves. A cavitation production part(17) on the suction side(11) and a curved part(19) on the blade are located at the same distance from the propeller axis(7). Therefore, bubbles caused by cavitation, are exploded not at the surface of the blade but away from the blade, reducing corrosion damage.
