    Abstract: A homopolar machine produces an axial counter force on the rotating shaft to compensate for the load on the shaft's thrust bearing to reduce wear and noise and prolong bearing life. The counter force is produced through magnetic interaction between the shaft and the machine's field coils and is created by changing the current excitation of the field coils, which results in a magnetic flux asymmetry in an inner flux return coupled to the shaft. The homopolar machine may also have a configuration that uses current collectors that maintain substantially constant contact pressure in the presence of high magnetic fields to improve current collector performance. The current collectors are flexible and may be made from either electrically conductive fibers or stacked strips such that they bear up against the armature so that the pressure is maintained by the spring constant of the current collector material. The homopolar machine may also have a configuration where the brushes are oriented so that the current is aligned as much as is practical with the local magnetic field lines so as to reduce the lateral electromagnetic forces on the brushes.

A pulse forming network provides pulsed energy to the electromagnetic gun, and the pulse forming network is cylindrical in shape so as to be rotatable within a cylindrical bulkhead within the ship. The pulse forming network may rotate in unison with the gun barrel allowing cables to couple the pulse forming network and the cable barrel. The pulse forming network includes wedge shaped capacitors that, when positioned sided by side, collectively form a substantially circular shape.

    Abstract: An apparatus for producing a stable, high pressure plasma column with long length, and high axial uniformity. Rotating a gas-filled tube about an horizontal axis creates a vortex with minimal, or no shear flow. Such a vortex provides a stable equilibrium for a central column of high temperature gas and plasma when, for a given rotation speed, the centrifugal force dominates over the gravitational force inside the smallest radial dimension of the containment envelope. For gas pressures sufficiently high that the particle mean free path is short compared with the thickness of the gas layer between the central plasma column and the wall, thermal transport across this sheath layer is small and its temperature is low. High pressure discharges inside a rotating envelope may be sustained by a variety of means, including electrical, electromagnetic and chemical; they may find application in plasma torches, light sources, etc. One preferred embodiment used direct current between co-rotating electrodes to sustain a one-meter-long plasma column less than 5 mm in diameter. Another preferred embodiment employed microwave heating to produce a perfectly centered plasma flame 0.5 meters long into which tens of kilowatts of power can be coupled.
