A device and method which combine electromagnetic accel
eration with acceleration by high-pres sure gases derived from
chemical energy to achieve high slug speeds. In one embodi
ment the device includes a cylindrical metal tube having an
outer diameter and an inner diameter and a central channel; at
least one conductive coil surrounding the metal tube; a metal
slug disposed within the central channel; a conducting central
electrode, having a centrally formed cavity; a conducting rod
having at least one cavity including a propellant, wherein a ?rst portion of the conducting rod is attached to the metal slug
at a connection point, a second portion of the conducting rod
extends between the metal slug and the central electrode, and a third portion of the conducting rod extends within the cavity
of the central electrode such that a space is formed between
the end of the third portion and the back of the cavity within
the central electrode; and an insulator disposed within the
central channel and surrounding the conducting central elec
trode and the second portion of the conducting rod except at
the connection point. When a current is applied to the metal
tube, the central electrode, and the at least one conductive coil causes the conducting rod to break with resultant generation
of a plasma which ignites the propellant such that the energy
from the propellant and electromagnetic forces accelerate the
slug to speeds greater than are achievable by the propellant
alone.
