Abstract
The invention, as embodied herein, comprises a new composition that provides different outputs depending upon the level of stimulus supplied to the composition. More specifically, if the composition is subjected to a weak shock, the composition produces fragments that burn upon their surfaces. If the composition is subjected to a strong shock, the bulk of the fragments will initiate, and, depending upon the make-up of the fragments, an explosive, propellant, or pyrotechnic, a different output will result.
Claims10
A composition, comprising:
- a plurality of shock insensitive, energetic fragments, each fragment a complete energetic formulation comprising at least two different components selected from the group of explosive particles, fuel, oxidizer, and binder;
- and,
- a base material to hold the plurality of fragments together wherein a weak shock results in ignition of a surface of the fragments and a strong shock results in initiation of the fragments.
A warhead, comprising:
- a plurality of shock insensitive, energetic fragments, each fragment a complete energetic formulation comprising at least two different components selected from the group of explosive particles, fuel, oxidizer, and binder;
- a base material to hold the plurality of fragments together wherein a weak shock results in ignition of a surface of the fragments and a strong shock results in initiation of the fragments;
- an explosive booster material, proximate to initiation means, to provide a weak shock;
- and,
- a metal case, surrounding the base material.
