Abstract


In this effort, a series of BKNO3 and nitrocellulose based igniters were formulated. Their thermodynamic output and gaseous properties were calculated. Their laboratory scale sensitivities were demonstrated to be significantly better than that of benite. Their performance characteristics based on closed bomb were evaluated and compared to that of both black powder and benite. These new igniters are more akin to benite in terms of relative force, and are quite varied with regard to relative quickness and relative vivacity. These new igniter formulations will provide gun system designers a means to vary the brisance and speed with which an igniter exerts its mechanism of action on the propellant, thus allowing them to tailor the ignition system through choice of material.
