ABSTRACT:
Hypervelocity magnetic induction accelerators are disclosed which create a traveling magnetic wave behind a projectile without the use of sliding contacts or multiple triggered switches. Inductive and resistive parameters are established as a function of position along a stator coil to obtain the magnetic wave in response to the pulsed DC power source. The ratio of the resistance to the inductance is a decreasing function of position from the breech to the muzzle. In a preferred embodiment the stator coil has a multiplicity of stages, and the DC pulse is delayed by inductances to progressively excite the stages, and the current from the pulse is fed through resistances to provide voltages for diverting the current to the next stages. In an alternative embodiment the magnectic field from the stator coil progressively diffuses through a tapered conductive or ferromagnetic sleeve disposed in the stator coil.
