US12710255 - 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.

The patent describes a linear shaped charge electro-explosive (LSCe) device that utilizes a backside initiator and booster charge to enhance the shockwave produced during detonation, resulting in a more powerful shaped charge jet. The device can be manufactured using additive techniques, allowing for scalability and optimization of its components for improved performance compared to traditional linear shaped charges.

Claim 1

1 . A linear shaped charge electro-explosive (LSCe) device, comprising: a non-fluted linear shape charge (LSC) including a housing oriented along an axis, a main charge formed in the housing and compressed to form a single, contiguous V-shaped channel whose apex lies along the axis and a single solid V-shaped liner in direct contact with the surface of the main charge, a tapered booster charge having a lower surface in direct and intimate contact with a portion of the main charge opposite the apex of the V-shaped channel and an upper surface, said lower surface being broader than said upper surface, an initiator in direct contact with the upper surface of the booster charge, wherein the initiator detonates in response to an electric stimulus to produce a shockwave that propagates through and detonates the booster charge magnifying the shockwave opposite the apex axis of the V-shaped channel, which in turn propagates through and detonates the main charge further magnifying the shockwave that collapses the single solid V-shaped liner and projects forward a single shaped charge jet. a non-fluted linear shape charge (LSC) including a housing oriented along an axis, a main charge formed in the housing and compressed to form a single, contiguous V-shaped channel whose apex lies along the axis and a single solid V-shaped liner in direct contact with the surface of the main charge, a tapered booster charge having a lower surface in direct and intimate contact with a portion of the main charge opposite the apex of the V-shaped channel and an upper surface, said lower surface being broader than said upper surface, an initiator in direct contact with the upper surface of the booster charge, wherein the initiator detonates in response to an electric stimulus to produce a shockwave that propagates through and detonates the booster charge magnifying the shockwave opposite the apex axis of the V-shaped channel, which in turn propagates through and detonates the main charge further magnifying the shockwave that collapses the single solid V-shaped liner and projects forward a single shaped charge jet.
