Abstract:
A propellant composition for high temperature incendiary (HTI) devices to destroy chemical and/or biological agents present in an ambient environment, said propellant comprising:a dual modal propellant composition comprised of low bum rate propellant particles dispersed in a matrix of a high burn rate propellant, wherein said low bum rate propellant particles comprise ammonium perchlorate (AP) as an oxidizer, a hydroxyl-terminated polybutadiene (HTPB) and a burn rate suppressant in an amount sufficient to achieve a burn rate of less than about 0.25 inches per second (ips) at a pressure condition of 1,000 psi, and wherein said high bum rate propellant comprises ammonium Perchlorate (AP) as an oxidizer, a hydroxyl-terminated polybutadiene (HTPB) and a burn rate accelerator in an amount sufficient to achieve a burn rate of at least about 1.00 inches per second (ips) at a pressure condition of 1.000 psi, and wherein combustion of said high burn rate propellant generates combustion eases which expel ignited low burn rate propellant particles in the ambient environment, which ignited low burn rate propellant particles thereby continue burning so as to destroy the chemical and/or biological agents present in the ambient environment.
