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

This disclosure relates to a stabilized plasma injector device specifically adapted to incubate, shape and develop plasma under the influence of an adjustable electromagnetic field to provide ignition and further promote energy coupling between the plasma and a combustible mass. The device includes a pair of shaped coils one of which is evaporated to form the plasma and the other coil provides the electromagnetic force field to influence the characteristic arc symmetry and the energy coupling between the plasma and the surrounding combustible mass.

Method and apparatus for providing a stabilized plasma arc

The present invention relates to an innovative, safe, explosive device. The device has many potential fields of utility, including, but not limited to mining, oil exploration, seismology, and particularly to shaped charges. These shaped charges may be used as a well perforation system using energetic, electrically-activated reactive blends in place of high explosives. The reactive blends are highly impact inert and relatively thermally inert until activated. The proposed system requires no conventional explosives and it is environmentally benign. The system and its components can be shipped and transported easily with little concern for premature explosion. It also needs no special handling or packing. The performance in oil and gas well perforation can be expected to exceed that of conventional explosive techniques.
