Abstract:

A pyrogen igniter for small nozzle applications has a high initial output. High initial output and long duration burning are achieved through utilization of a slow burning igniter main charge in conjunction with a booster pellet. A nozzle plate focuses and directs the output of the igniter as a gas jet while shielding the interior of the igniter as a gas jet while shielding the interior of the igniter from exterior temperature and pressure fluctuations which might otherwise operate to extinguish the igniter. A flush bridgewirepressed prime igniter configuration and the elimination of loose powder in the igniter facilitates economical production and long shelf-life.
