摘要： The embodiments are directed to firing trains. The disclosed firing trains include an insensitive acceptor pellet having a proximal end, a distal end, and a plurality of relative percent theoretical maximum density (TMD) zones from the proximal end to the distal end. A donor pellet is adjacent to the insensitive acceptor pellet and is configured to initiate the insensitive acceptor pellet.

摘要： Shock resistant mounting structures for fuze systems. The shock resistant mounting structures may comprise: a shock resistant fuze cap and a shock resistant collar. The shock resistant fuze cap may comprise a circular cap housing and a plurality of cripple studs disposed within the circular cap housing. The circular cap housing may be adapted to engage an upper portion of a fuze and may be adapted to snugly fit within a fuze well. The shock resistant collar may comprise a ring-shaped housing and one or more cripple studs radially disposed within the ring-shaped housing. The ring-shaped housing may have a center opening adapted to engage a fuze body. When installed, the shock resistant fuze cap and shock resistant collar may be disposed within the fuze well and may minimize, prevent, or divert shock loading energy from entering a fuze.

摘要： Embodiments are directed to a density gradient booster pellet having a proximal end, a distal end, and a central longitudinal axis spanning from the proximal end to the distal end. The density gradient booster has a plurality of density zones from the proximal end to the distal end. The proximal end is in adjacent contact with an insensitive explosive fill.

摘要： The embodiments are directed to methods of initiating insensitive explosive formulations. The disclosed methods include positioning a donor explosive pellet adjacent to an insensitive acceptor explosive pellet having a plurality of relative percent theoretical maximum density (TMD) zones. The insensitive acceptor explosive pellet is adjacent to an insensitive explosive fill. Upon donor explosive pellet initiation, the donor explosive pellet provides a shock stimulus to the insensitive acceptor explosive pellet, which initiates the insensitive acceptor explosive pellet, causing a detonation wave to be driven through the plurality of relative percent TMD zones and into the insensitive explosive fill.

摘要： Shock resistant mounting structures for fuze systems. The shock resistant mounting structures may comprise: a shock resistant base cap and a shock resistant washer. The shock resistant base cap may comprise a circular cap housing and a plurality of first cripple studs disposed within the circular cap housing. The circular cap housing may be configured to engage a flange end of a fuze and may be adapted to snugly fit within a fuze well. The shock resistant washer may comprise a ring-shaped housing and one or more second cripple studs radially disposed within the ring-shaped housing. The ring-shaped housing may have a center opening adapted to engage a fuze body. When installed, the shock resistant base cap and shock resistant washer may be disposed within the fuze well and may minimize or divert shock loading energy from entering a fuze.
