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.
