Common igniters such as black Powder, Gun powder, and boron potassium nitrate (BKNO3) are routinely employed in all calibers of gun systems. Armament Research Development Engineering Center (ARDEC) has pursued efforts to improve the ignition of propellants which has been demonstrated to be the root cause of many tribulations for propulsion systems. This leaded to the development of several extrudable nitrocellulose-BKNO3 based igniter materials that are more energetic, and exhibit smaller ignition delay times than most traditional igniters. Demonstration is done via static firing. High speed video during static CV testing has demonstrated significantly more consistent, intense, and rapid flame generation in comparison to BKNO3 pellets and other granular formulations leading to improved ignition effectiveness of the propellant bed. The method of extrusion was involved using single or twin screw extruder for the purpose of development of strands.
