FEASIBILITY STUDY OF A HYDROMAGNETIC WATERJET PROPULSION SYSTEM

This paper presents an analytical study for the determination of the performance characteristics of a proposed underwater waterjet propulsion system. The system is powered by the viscous drag pumping action of spherical micron-sized ferromagnetic particles accelerated by an external magnetic field. Some preliminary geometry details and thrust characteristics of a small system using a superconducting magnet and associated hardware are presented. The thrust/weight ratio of the proposed system is shown to be much less than one over the range of design parameters considered, placing serious limitations on the use of such a system.
