ABSTRACT:
A propulsion system designed to propel submarine and surface vessels by discharging fluid rearwardly with a reaction of increased force that is approximately twenty percent greater than that possible with conventional propeller systems. Its conical/tapered housing is mounted to the inside bottom surface and transom of a marine vessel hull whereby a keyhole-shaped inlet opening directs a large volume of seawater into the housing's wider end. Seawater then flows across several increasingly smaller propellers positioned within the housing. A reverse and steering assembly with a movable gate can be optionally aligned with the discharge end of the housing to control the direction of marine vessel movement. Size is not a limiting factor for the present invention and its operation is virtually silent. Also, its inlet opening is always below the water level so priming is never needed and no transmission is required. Recreational, commercial, and military applications are contemplated.
