Synergetic Effect of the Chemical Compositions in an Energetic Device

Abstract

A pyrotechnic device or subsystem, such as a well-known M201A1 fuze shown below, is constructed typically with a number of energetic compositions. Once triggered, it undergoes a series of self-sustained exothermal reaction for distinctive pyrotechnic effect or to initiate a main pyrotechnic charge such as a smoke grenade. However, the occurrence of those energetic events in between those compositions has been found hardly sequential, and deserves some close examination. This work, for the first time, presents strong evidence of some secondary reaction in between those energetic compositions which appears in much stronger intensity in terms of heat or energetic output. Those findings provide invaluable technical insight for the design and test of those pyrotechnic devices for failure mood analysis and improved performance.
