Note(s): Harbor Branch Oceanographic Institution, Inc. (HBOl) has developed a unique new electric propulsion device that maximizes thrust at significantly lower power and weight than other conventional propulsors used for undersea vehicles. Appropriate applications for the Electric Ring Propeller (ERP) include AUVs, UUVs, manned submersibles, swimmer delivery vehicles, diver propulsion devices, acoustic targets (e.g., Mk 30), surface ship maneuvering thrusters and recreational water craft. Because the propeller blades are attached and supported by a rotating ring at its circumference, there is no center hub. This facilitates towed arrays, fiber-optic links and other systems to be deployed directly through the center of the thruster. A number of prototypes with voltages ranging from 24 VDC - 120 VDC have been built and, tested, exhibiting performance of 0.1 lb. of thrust per watt. With syntactic foam nozzles the thruster and its control circuitry can be packaged in a compact, near-neutral buoyancy package.
