Marine propulsion system with cyclic blade pitch - uses paddle wheel inset in hull and with bevel gear transmission

摘要

A cyclic pitch control paddle wheel for a ship has the paddles (1) mounted between two rotating flanges (4) rigidly linked by a central axle and driven by bevel gears (14) linked to the engines. The pitch of the paddles varies cyclically for optimum drive. The system gives very good steering and drive control. The blades are mounted in the drive flanges or adjustable pivots to generate the pitch. One or two paddle wheels can be mounted in recessed drive ducts under the hull of the ship.
