Optimization of the initiation capability of a microdetonator

Abstract

The initiation capability of a microdetonator 0.9 mm in diameter and 3 mm in height is studied. The critical height of the lead azide explosive is 1.8 mm. The optimal ratio of the heights of the primary and secondary explosives in a microdetonator is determined to be 0.7-2.3. At an identical ratio of the primary and secondary explosive heights, the output pressure changes from the highest to the lowest value in the sequence from CL-20 to HMX and then to RDX.
