Abstract:
1. A method for making a gasless ignition system for igniting a material charge, comprising the steps of: providing a housing having a first end and an opposing second end and defining an elongate channel extending between the first and second ends; mechanically activating a reactive material comprising at least first and second elements; packing said housing with the mechanically activated reactive material; positioning an initiator element at the first end of the housing and in contact with the mechanically activated reactive material; and positioning the second end of the housing adjacent a combustible material, wherein, upon actuation of the initiator element, the mechanically activated reactive material burns from its point of ignition at the first end of the housing to the opposite second end of the housing to ignite the combustible material, wherein the gasless ignition system provides a delay measured as the time it takes for the mechanically activated reactive material to burn from its point of ignition at the first end of the housing to the opposite second end of the housing and the mechanically activated reactive material in said housing has an ignition input energy level, and wherein at least one of the duration of the delay and the ignition input energy level is selectively determined by varying at least one of the intensity and duration of the mechanical activation.
