Abstract

A high-power, low-speed, steerable underwater propulsion unit comprises paddles (4) mounted at the rim of a driven wheel (1) supported on a chassis (10). The paddles (4) are orthogonal to a reference plane defined by the surface of the driven wheel (1), and rotate freely about axes (5) orthogonal to said reference plane. The orientation of each paddle is varied by successive small rotational movements caused by a toothed wheel which cooperates with a cogged wheel (7), the cog axes being parallel to the axes of the paddles (4). The driven wheel is driven by driving wheels (2) which engage its periphery, thereby avoiding the need to transmit high torque at low speed via a shaft. Indeed the driven wheel is centreless. <IMAGE>
