Abstract

A gas generant charge comprises a heterogeneous mixture of between about 80 and about 95 wt % of a first gas generant composition 1) and between about 5 and about 20 wt % of a second gas generant composition 2), based on the total weight of 1) plus 2). The first gas generant composition 1) comprises between about 20 and about 40 wt % fuel A) and between about 20 and about 60 wt % oxidizer B). Between about 50 and about 85 wt % of the fuel A) is a triazole or tetrazole compound A.sup.1), and between about 15 and about 50 wt % of the fuel is, a water-soluble fuel A.sup.2). At least about 20 wt % of the oxidizer B), up to 100%, a transition metal oxide B.sup.1); balance of the oxidizer is selected from the group B.sup.2) consisting of alkali and/or alkaline earth metal nitrates, chlorates or perchlorates. The second gas generant composition 2) comprises between about 30 and about 65 wt % of a fuel C) which is an organic compound containing only the elements carbon, hydrogen, and oxygen, the oxygen content being between about 35 and about 65 wt % of the organic compound, and an between about 35 and about 70 wt % of an oxidizer D) which is selected from the group consisting of alkali me…
