The invention provides a device for generating surface plasmas, for ignition of propellants. The invention provides a plurality of sheet fuses with insulating sheets separating each fuse. One of the fuses is complete, while the other fuses have a gap. The fuses are sheets formed into concentric coaxial cylinders. The complete fuse forms the outer most cylinder. The fuses sequentially become a plasma starting from the outer most fuse to the inner most fuse.

Sequential arc surface injector

Apparatus is disclosed which provides coaxial connection between a high energy power supply and a plurality of plasma injectors in a gun breech assembly over a plurality of high energy transmission coaxial cables without losing the coaxial nature of the high energy transmission path at the connections between the coaxial cables and the plasma injectors. The apparatus includes a conductive bell housing for surrounding the connections while providing access for securing the connections with the bell housing in place.

High power coaxial connection

The apparatus and method disclosed herein relates to the generation of primary and fuel-enriched plasma to provide ignition and delivery for large amounts of electrical and electrothermal power to a propellant mass. Particularly, the present invention enables the creation of zones of controlled combustion by initially incubating primary plasma in a capillary chamber and mixing the primary plasma with fuel in a fuel chamber thus creating a fuel-enriched plasma. The primary plasma and the fuel-enriched plasma are segregatively, collectively and substantially simultaneously injected into the propellant mass via outlet ports and nozzles. The capillary and fuel chambers, and the nozzles and outlet ports undergo staged disintegration at reaching predetermined pressures and temperatures and are thereby consumed in the combustion process.

Disintegrating injector for primary and fuel enriched plasma

Apparatus for providing a controlled increase in muzzle velocity of a projectile while reducing peak value of gas pressure inside a gun barrel. A cartridge includes an elongated body having a central bore divided into three chambers, with a fuel chamber separated from an oxidizer chamber and an elongated capillary chamber by a plurality of membranes. A fuse wire and a power supply vaporize a plasma base in the capillary chamber and provide a controlled jet to provide combustion between a second fuel in the fuel chamber and an oxidizer material in the oxidizer chamber. The power supply controls the fuel-oxidizer combustion rate to obtain a relatively steady pressure of long duration against the projectile which results in high projectile velocity with relatively low peak values of pressure in the gun barrel.
