ABSTRACT:
An ignition device for propellant of a projectile having its aft section ending deeply rearward within a shell case comprises a strand holder, a primer head, and flexible ignition strands with the primer head, when installed, being supported by the shell case and supporting the strand holder which in turn preferably supports the aft end of the projectile. The ignition strands, symmetrically disposed, contact the propellant and in preferred embodiments also contact the projectile, and/or the interior of the shell case, as well as the propellant, and extend along the body section of the strand holder and through conduits therein into a combustion chamber, formed intermediate the installed primer head and a platform section of the strand holder, and with the combustion chamber containing an igniter booster charge susceptible to ignition by a firing means adapted to be used with the primer head.
