Abstract

A multi-path impact type, inertia class, igniter for use with both rotating and non-rotating projectiles or warheads includes two or more stab type 'firing pins' that are arranged in a plane which is at 90.degree. to the center-line of the projectile. The firing pins are equally spaced apart on the plane and each bears directly upon a safety rupture-disc. The rupture-discs bear directly upon stab type primers, there being one primer per disc. Each firing pin has a sloped 'conic' surface forming a cam which is in direct contact with a conic body-of-rotation inertia mass which lies on the projectile center-line. Upon impact, the conic shaped mass moves forward at a high rate forcing the firing pins outward at a much reduced velocity relative to that of impact. The moving firing pins pierce the rupture-discs and enter the stab primers, thereby causing the actuation of the latter.
