Abstract:
1. A nitrocellulose-free, gas-generating composition adapted for use in a belt tensioning system, said composition consisting essentially of at least one nitrogen-containing organic fuel in a proportion of 55 to 70% by weight, an inorganic perchlorate oxidator in a proportion of 30 to 45% by weight, at least one combustion moderator in a proportion of between 2 and 5% by weight wherein said combustion moderator is at least one of the oxygen-containing compounds of Fe, Cu, Mn, Ti, V, Mo and Cr, and conventional adjuvants and additives in an amount of between 0 and 5% by weight, each in relation to the overall weight of said composition, wherein said nitrogen-containing organic fuel consists of 75 to 90% by weight of guanidine nitrate in admixture with 10 to 25% by weight of at least one further compound selected from the group consisting of nitroguanidine, nitrotriazolon, hexogen, octogen, ethylene, diamine dinitrate, triaminoguanidine nitrate, azobisformamidine dinitrate, each in relation to the fuel, and said composition having a pressure exponent of less than 0.35 and a combustion rate at 200 bar of at least 40 mm/s.
