Abstract
A sliding breech block system and method for repetitive firing of electrothermal cartridges in an electrothermal gun are provided. The sliding breech block system comprises a high-power, low resistance, flexible coaxial cable which is routed through a sliding breech-block, a pulse-forming network, and two groups of bristles for conducting the pulses from the breech block to the electrothermal cartridge. The power cable comprises two layers of individually insulated, multi-strand wires both within a jacket of braided wire. The method for repetitively igniting an electrothermal gun comprises the steps of fixedly attaching tightly-packed, brass bristles to the electrothermal cartridge conductors, sliding the breech-block into position so that its surface contacts the brass bristles of the cartridge, and supplying an electrical current from the pulse-forming network to the cartridge by means of a flexible high-power cable.
