Abstract:
An underwater propulsion system:a submersible having a cylindrically-shaped hull and a nose portion connected forward on said hull; a tapered portion having a coaxially tapered curvature surface mounted aft on said hull, said hull, nose portion and aft tapered curvature surface portion being coaxially symmetrically disposed around a common longitudinally extending axis, said coaxially disposed aft tapered curvature surface portion having a leading end essentially the same diameter as said hull and a symmetrical apex at its trailing end on said longitudinal axis, and said aft tapered curvature surface portion having symmetrical rounded lateral contours laterally disposed from said longitudinal axis and rounded longitudinal contours extending from said leading end to said symmetrical apex; a high-volume pump sealed and secured to the inside of said leading end to extend across said aft tapered curvature portion to create volumes of pressurized water from ambient water; and a plurality of equal-distantly-spaced-apart jets extending through said aft tapered curvature surface portion and being arranged in a circumferentially extending row around said aft tapered curvature surface portion, each of said jets being angled to point outwardly from said aft tapered curvature surface portion, and emitting jetted water from said volumes of pressurized water to form a spinning toroidal vortex of swirling jetted water on a down slope surface of said aft tapered curvature surface portion.
