Abstract
A subsurface propeller module, using Voith Schneider propeller technology, is provided for use in underwater vehicle dynamic motion control. One or more modules are mounted between nose and body sections of the vehicle such that their axes of rotation coincide with the longitudinal centerline of the vehicle. This enables the module to thrust in any direction normal to the direction of travel. Wiring for power and sensors can be routed through structural conduits connecting the nose section to the main body of the vehicle and supporting the propeller modules. The structural conduits can be shaped to provide support for the nose and body sections, and to have minimal hydrodynamic impact on vehicle forward motion or module thrust. A sealed housing is provided for the motors and control actuators of the propeller modules.
