Claims
- 1. A plasma injector assembly for use in a munition having a central axis, the plasma injector assembly comprising:a stub case for attachment to the munition along the central axis; an anode positioned in the stub case; a cathode positioned in the stub case, wherein the anode and the cathode are located at opposite ends of a plasma creation region, wherein the plasma creation region is aligned along a planar depth that is substantially transverse to the central axis; and a vent assembly disposed between the plasma creation region and a propellant region.
- 2. The plasma injector assembly of claim 1, and further comprising a conductive wire that interconnects the anode and the cathode.
- 3. The plasma injector assembly of claim 1, wherein the plasma injector assembly has a tube with a first end and a second end, wherein the anode is placed in the first end, wherein the cathode is placed in the second end, and wherein the tube has at least one aperture formed therein such that a region inside the tube is in communication with the vent assembly.
- 4. The plasma injector assembly of claim 3, wherein the plasma injector assembly substantially ignites the propellant within about 1-2 milliseconds.
- 5. The plasma injector assembly of claim 1, wherein the plasma injector assembly produces plasma that is directed into the propellant region by a plurality of apertures in the vent assembly.
- 6. A plasma injector assembly for use in a munition having a central axis, the plasma injector comprising:a stub case for attachment to the munition along the central axis; a tube having a first end and a second end, wherein the tube has a central bore extending therethrough, wherein the tube has at least one aperture that is operably connected to the central bore, and wherein the tube is mounted to the stub case in an orientation that is substantially transverse to the central axis; an anode positioned proximate the first end; a cathode positioned proximate the second end; a conductive wire extending through the central bore between the anode and the cathode and operably connecting the anode and the cathode; and a vent assembly having an aft end and a forward end wherein the aft end is in communication with the tube and a forward end is in communication with a propellant.
