Title:
VIBRATING FORCE SUPPRESSING DEVICE FOR PROPELLER
Document Type and Number:
Japanese Patent JP2014125125
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce friction resistance of a ship to water by blowing air into water and to suppress increment of vibrating force for a propeller due to winding air bubble by the propeller.SOLUTION: There is provided an air blowing part which blows out air into water from an air blowing port arranged at the bottom part of the side of the bow. There is provided an air recovery part 7 recovering air moving from the bow to the stern from an air recovering port 7a which is provided on the bottom part. The air recovering port 7a is formed at a position on the bow side rather than a propeller 4 which ranging at approximately corresponding to at least the propeller 4 on the ship width direction. There is provided an air re-blowing part 9 having an air re-blowing port 9a for re-blowing the air recovered from the air recovering part 7 into water. The air re-blowing port 9a is arranged on a bottom surface 1d on the stern side so that air bubble 8 of the air covers a range approximately corresponding to the propeller 4 in width direction of the ship.
