Abstract
A ship has an electromagnetic thrust generator including a cylindrical magnet in which there is arranged a helical duct for conducting sea water. The magnet includes a coil housing in which a superconducting coil is disposed. The duct includes an outer wall disposed opposite the internal surface of the coil housing. Electrode members are mounted on inner and outer walls of the duct to create an electrical field across the duct.
Claims3
An electromagnetic thrust generator, comprising:
- a housing having a circular cylindrical interior surface defining an interior space extending through said housing, said space having a longitudinal center axis;
- a superconducting electrical coil arrangement disposed within said housing for generating a magnetic field within said space,
- a helical duct arranged coaxially within said space, said duct formed by:
- a circular cylindrical outer wall arranged opposite said interior surface of said housing,
- a circular cylindrical inner wall spaced radially inwardly of said outer wall, and
- intermediate walls interconnecting said outer and inner walls to form therewith a helical passage of substantially rectangular cross section and having a fluid inlet and a fluid outlet spaced longitudinally apart,
- a first electrode member mounted in said duct on an interior face of said inner wall;
- and
- a second electrode member mounted in said duct on an interior face of said outer wall and being of opposite polarity than said first electrode for creating an electrical field across said duct.
