Abstract
Gas generating compositions are provided containing silicone, a metal or nonmetal perchlorate oxidizer, and a coolant selected from the group including metal carbonates, metal bicarbonates, metal oxalates, and metal hydroxides. These compositions exhibit rapid and sustained burn rates at ambient pressure while maintaining acceptable combustion temperatures.
Claims13
A gas generant composition consisting essentially of:
- silicone as a fuel at about 10–25% by weight;
- an oxidizer selected from the group consisting of metal and nonmetal perchlorates at about 30–85% by weight;
- and
- a coolant selected from the group consisting of alkali, alkaline earth, and transitional metal carbonates, bicarbonates, oxalates, and hydroxides at about 1–30% by weight, said percentages stated by weight of the gas generant composition.

A gas generant composition consisting essentially of:
- silicone as a fuel at 20–25%;
- a primary oxidizer selected from the group consisting of metal and nonmetal perchlorates at 30–60%;
- and
- a coolant selected from the group consisting of alkali, alkaline earth, and transitional metal carbonates, oxalates, bicarbonates, and hydroxides at 20–30%, said percentages stated by weight of said gas generant composition.
