Title:
WATER SUCTION DUCT STRUCTURE FOR PROPELLER OF JET- PROPELLED BOAT
Document Type and Number:
Japanese Patent JP2001048091
Kind Code:
A
Abstract:
To reduce noise caused by water pressure fluctuation by an impeller and to improve a degree of freedom of change in form of a water suction duct.
By fixing a duct component 33 formed by an FRP separate from a hull member 1 to a duct reinforcing member 32 of the hull member 1 via adhesive 35 which is a vibration damping member, vibration transmitted to the duct component 33 becomes difficult to be transmitted to the hull member 1 because the duct component 33 is fixed to the hull member 1 via the vibration damping member 35, even if water pressure fluctuation propagates in water within the water suction duct 11 and is transmitted as vibration to the component 33.
