Title:
SYSTEM FOR REDUCING TIP VORTEX CAVITATION BY MEANS OF WATER DISCHARGE AND SUCTION CONTROL
Document Type and Number:
WIPO Patent Application WO/2023/243789
Kind Code:
A1
Abstract:
The present invention has a plurality of discharge and suction holes formed in propeller blades so as to reduce tip vortex cavitation that occurs around the propeller blades when the propeller for propulsion that generates propulsive force for a ship to sail in the sea rotates, and can reduce the tip vortex cavitation by means of water discharge and suction whereby water is discharged to the outside or outside water is sucked in through the plurality of discharge and suction holes, thereby reducing underwater noise and hull vibration. The invention comprises a propeller (100), water transport pipes (200), water supply/suction parts (300), and a control part (400).
