Magnetic levitation and MHD propulsion

Journal de Physique III, 1994
Magnetic levitation and MHD propulsion are now attracting attention in several countries. Different superconducting MagLev and MHD systems will be described concentrating on, above all, the electromagnetic aspect. Some programmes occurring throughout the world will be described.

Magnetic discretion of naval propulsion machines

Journal of Magnetism and Magnetic Materials, 2002
Abstract Magnetic silencing is required for specific naval applications, especially for some oceanographic or military ships. It is, therefore, necessary to study the field radiated by electrical propulsion motors. This can be achieved using a numerical modelling based on magnetic moments.

Magnetohydrodynamic ship propulsion with superconducting magnets

Journal of Superconductivity, 1988
The feasibility of magnetohydrodynamic (MHD) ship propulsion using superconducting magnets is reviewed in light of recent advances in high-temperature superconductivity. The scaling relations for the electrical and hydraulic efficiencies of MHD pump-jets show that overall efficiencies >50% are feasible at speeds of 40 knots and higher provided that ...

Gradientless propulsion of magnetic bubble domains

Journal of Magnetism and Magnetic Materials, 1976
Magnetic bubble domains are propagated in a magnetic medium in a desired direction using magnetic fields which have no spatial gradients. This is in contrast with conventional propagation techniques where magnetic overlays have to be used with applied magnetic fields in order to move domains.

Magnetic levitation in linear propulsion machines

Journal of the Franklin Institute, 1984
A simple magnetic levitation system is analyzed; the results obtained yield insight into the lift-thrust mechanism and demonstrate, through the magnetic Reynolds number, the interplay of the electric and geometric parameters.

Magnetic propulsion along an orbiting grain stream

Journal of Spacecraft and Rockets, 1986
If a stream of grains is in orbit about a central body such as the sun, a vehicle could accelerate along the stream using magnetic propulsion. After reaching a high velocity, i.e., a significant fraction of the speed of light, the vehicle could reach the end of the stream and enter free space.

Problems of Magnetic Propulsion of Plasma

1960
In the case where a plasma structure can be made to have ideal or nearly ideal diamagnetic properties a magnetic field will act on the gaseous ionized boundary like a piston and will impart net momentum to the configuration.
