Title:
SUBMARINE BOAT AND DISTRIBUTION MEASURING METHOD
Document Type and Number:
Japanese Patent JP2002145187
Kind Code:
A
Abstract:
To reduce the number of propellers to obtain large turning round moment.
A submarine boat 20 has three propellers 56 (56s-56c) in the rear end part of a body 22. Each propeller 56 has the rear end inclined inward, and gives a thrust of a component parallel to the shaft line 58 and a component perpendicularly crossing to the shaft line 58 to the body 22. A driving ballast mounting part 30 and a floating ballast mounting part 32 are installed in a front end chamber 28 of the body 22. When the driving ballast is discarded and only the floating ballast is mounted, the center of gravity of the submarine boat 20 is positioned in GB of the central part in the front and rear direction of the body 22 under the center of buoyancy 62.
