Abstract
A composition for generating a non-toxic, non-flammable, odorless gas is disclosed wherein the propellant of said composition is a mixture of about 30% by weight to about 45% by weight KClO.sub.4 with about 55% by weight to 706 by weight of guanidine nitrate or a gas-generative effective derivative thereof with about 1% by weight to 3% by weight cellulose acetate butyrate, the oxidation ratio of oxidizer to fuel being about 0.92 to about 0.98. The method of using said composition is also disclosed.
Claims24
A composition for generating a low particulate non-toxic, non-flammable, odorless and colorless gas, said composition comprising a propellant mixture of about 55 to about 70% by weight of guanidine nitrate (GN) and/or a gas-generative effective derivative thereof with about 30 to about 45% by weight of a perchlorate of an alkali metal and a minor combustion modifying effective amount of cellulose acetate butyrate (CAB).
A method for generating a stable low particulate non-toxic, non-flammable, odorless and colorless gas comprising the steps of:
- a) providing an enclosed pressure chamber having exit ports;
- b) disposing within said chamber a gas-generative composition comprising a propellant mixture of about 55% to about 70% by weight of GN and/or a gas-generative effective derivative thereof with about 30 to about 45% by weight of a perchlorate of an alkali metal and a minor combustion modifying effective amount of CAB;
- and
- c) providing means for igniting said gas-generative composition upon detection by a sensor of the pressure chamber being subjected to a sudden deceleration, whereby said gas is substantially instantly generated and conducted through the exit ports of said pressure chamber.
