Abstract
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.
Claims17
A firing train, comprising:
- an insensitive cylindrically-shaped acceptor explosive pellet having a proximal end, a distal end, and a central longitudinal axis spanning from said proximal end to said distal end;
- wherein said insensitive cylindrically-shaped acceptor explosive pellet having a plurality of relative percent theoretical maximum density (TMD) zones from said proximal end to said distal end;
- wherein sensitivity of said insensitive cylindrically-shaped acceptor explosive pellet decreases from said proximal end to said distal end, wherein explosive output of said insensitive cylindrically-shaped acceptor explosive pellet increases from said proximal end to said distal end;
- wherein said plurality of relative percent TMD zones having an increasing relative percent TMD from said proximal end to said distal end;
- a donor explosive pellet having a donor explosive pellet central longitudinal axis, said donor explosive pellet positioned in intimate adjacent contact with said proximal end of said insensitive cylindrically-shaped acceptor explosive pellet, wherein said central longitudinal axis of said insensitive cylindrically-shaped acceptor explosive pellet and said donor explosive pellet central longitudinal axis are not aligned;
- wherein said distal end of said insensitive cylindrically-shaped acceptor explosive pellet is in adjacent contact with an insensitive explosive fill;
- and
- wherein said donor explosive pellet is configured to initiate, said initiation causing said donor explosive pellet to provide a shock stimulus to said insensitive cylindrically-shaped acceptor explosive pellet and initiate said insensitive cylindrically-shaped acceptor explosive pellet.

A firing train in the aft end of a munition, comprising:
- a munition having an aft end and a munition case;
- an insensitive explosive fill housed in said munition case;
- a hollow fuze well attached to said aft end, said munition case concentric about said hollow fuze well, said hollow fuze well housing a munition fuze;
- a donor explosive pellet inside said hollow fuze well, said donor explosive pellet having a first end, a second end, and a donor explosive pellet central longitudinal axis;
- an insensitive cylindrically-shaped acceptor explosive pellet housed inside said hollow fuze well, said insensitive cylindrically-shaped acceptor explosive pellet having a proximal end, a distal end, and a central longitudinal axis spanning from said proximal end to said distal end, wherein distal end is in adjacent contact with said insensitive explosive fill;
- wherein said donor explosive pellet is positioned in intimate adjacent contact with said proximal end of said insensitive cylindrically-shaped acceptor explosive pellet, wherein said central longitudinal axis of said insensitive cylindrically-shaped acceptor explosive pellet and said donor explosive pellet central longitudinal axis are not aligned;
- and
- wherein said donor explosive pellet is configured to initiate, said initiation causing said donor explosive pellet to provide a shock stimulus to said insensitive cylindrically-shaped acceptor pellet and initiate said insensitive cylindrically-shaped acceptor pellet.
