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.
