  • Sequential arc surface injector
    Patent number: 6119599
    Abstract: 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.

  • Method and apparatus for providing a stabilized plasma arc
    Patent number: 5880427
    Abstract: 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.
