Title:
CATERPILLAR PROPULSION TYPE HIGH SPEED SHIP
Document Type and Number:
Japanese Patent JPS63305013
Kind Code:
A
Abstract:
PURPOSE:To improve high speed sailing and to enable execution of running on a land, by a method wherein caterpillars with paddles are disposed to outside of the two gunwales of a ship hull, when the caterpillar is moved down, it is submerged in water, and it strokes water in water to produce a running force. CONSTITUTION:After, paddles 15 are regulated through a flange 18 so that they have an angle of elevation of 45 deg. with a belt 16 when paddles 15 are moved to below, an engine is driven to drive caterpillars 13. As a result, the paddle 15 strokes water to start sailing. Since the paddle 15 has an angle of elevation of 45 deg., buoyancy is generated to lift up a ship hull, and water resistance is reduced. When a speed is increased to a specified value, the paddle 15 is regulated so that it is inclined at 90 deg. with the belt 16. This method maximizes the thrust of the paddle 15. The paddle 15 is displaced to a state in which it is positioned parallel to the belt 16 at a point of time when it is moved around a rear drive wheel 12a. This constitution provides a speed of 100 knot or more.
