Title:
OPEN CORE CONTINUOUS HELICAL FIN MARINE DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/100127
Kind Code:
A3
Abstract:
An open core continuous helical fin marine drive system for use with surface and subsurface marine vessels has a cylindrical fluid container nested within a nacelle enclosure having an intake port and an exhaust port tailpipe. The cylindrical fluid container is driven by a fluid container drive motor through a gear assembly including a pinion gear connected to the fluid container drive motor and an underwater ring gear connected to the cylindrical fluid container. A plurality of continuous helical fins connected along the inner wall of the cylindrical fluid container is positioned about a hollow center core and creates a horizontal centripetal fluid vortex thread along the hollow center core as the cylindrical fluid container rotates. An inflatable marine bladder is positioned aft of the cylindrical fluid container and can be engaged to an inflated configuration in order to compress the exiting water flow through the exhaust port tailpipe.
