Shock insensitive initiating devices

specialactivitieSK - 21-10-2014 at 11:21

The invention relates to a shock insensitive explosive train initiating dce including a thin elongated metal casing containing a quantity of hydrated metal picrate therein, a thermite igniter composition disposed adjacent to the hydrated metal picrate charge[ and an ignition means selected from ignition means consisting of an electric match and a length of fuze cord. In a specific example, the hydrated metal picrate charge is barium picrate hydrate which may be disposed in an open (FIG. 1) or a sealed (FIG. 2) copper or aluminum casing. In the embodiment of FIG. 3, a tin/zinc alloy, protective, safety cover is disposed over a portion of the hydrated metal picrate. This safety cover has a low melting point (200.degree. C.) and is adapted to melt in the event of a fire to thereby 'unconfine' the hydrate metal picrate charge prior to it reaching explosion temperature of approximately 341.degree. C.
