Linear shaped charge electro-explosive (LSCe) device with a backside boosted initiation
A linear shaped charge electro-explosive (LSCe) device integrates an initiator and booster charge on the backside of a main charge and solid V-shaped liner. The initiator is responsive to an electric stimulus to produce a shockwave that detonates and propagates through the booster charge to magnify the shockwave, which in turn detonates and propagates the main charge to further magnify the shockwave that collapses the solid V-shaped liner and projects forward a shaped charge jet. A wave shaper may be positioned in the booster or main charge to flatten the wave front into an approximately planar wave front when the magnified shockwave interacts with the V-shaped liner. The wave shaper and main charge and possibly all components energetic and non-energetic, except the initiator, may be formed using additive manufacturing. Alternately, only non-energetic components may be formed using additive manufacturing. The device may be formed into a linear, are or ring-shaped form factor. Additive manufacturing enables device scaling and optimal device function resulting in enhanced shaped jet output beyond those of traditional LSCs.

EXPLOSIVE FIRING TRAIN WITH A SINGLE EXPLOSIVE TRANSFER INTERFACE
An EFI or LEEFI provides enhanced detonation energy sufficient to directly detonate a main charge to improve the reliability and ease the qualification of an explosive firing train. This is accomplished by forming the EFI's output charge from an explosive material typically used as a booster explosive (e.g., PBXN-5, CH-6 and Composition A5) rather than a primary explosive and making the diameter of the output charge greater than the diameter of the barrel thus increasing the total mass of the output charge. The explosive firing train now requires only a single explosive transfer interface. For use in military grade munitions, the EFI's casing is formed with one or more vent holes radially adjacent the output charge.
