A MULTI-LAYER EXPLODING FOIL AND MULTIPLE FLYER BASED SLAPPER DETONATOR

摘要

The invention relates to a multi-layer exploding foil and multi flyer based slapper detonator comprising (a) a squib comprising a multiple layered exploding foil etched on a printed circuit board (PCB) substrate, the foil being capable of vaporizing into plasma generating shock waves on receiving electrical energy; (b) a multiplicity of flyers, disposed spatially proximal to the exploding foil, being configured to be propelled on receiving the shock waves from the exploding foil; ( c) a high alumina ceramic barrel on top of the aluminium flyer configured to cause smooth and even cutting of both the flyers on on receiving the shock waves from the exploding foil thereby freeing flyers to be propelled; (d) a ceramic holder configured to facilitate assembly of the squib with said multiplicity of flyers and the barrel; (e) a HNS-IV(2, 2', 4,4',6,6' Hexanitrostilbene) explosive pellet, contained in stainless steel tube and placed on the top of the barrel, the explosive pellet being capable of detonation on receiving impact of the propelled flyers; and (f) a nickle enclosure for enclosing and sealing the said exploding foil, flyers, barrel and HNS-IV pellet.
