ABSTRACT:
A wall thruster for surface or submarine vessels that is cavitation resistant and does not require a hull duct. The invention comprises an impeller mounted in a swirl chamber such that seawater is rotated under pressure. The water is then discharged through streamlined nozzles in a direction to minimize mixing with the flow of the water being drawn into the impeller.
