ABSTRACT:
A gas generator composition is provided which burns stably and has a high burning rate at low temperature ranges while maintaining its performance such as specific impulse when used in the propulsive engine. Furthermore, a gas generator composition whose dependence on pressure and temperature is small is provided. The gas generator comprises an aliphatic polyether having azidomethyl groups and hydroxyl groups, a curing agent for curing the aliphatic polyether, an oxidizer for conducting oxidation reaction, and a burning rate modifier for modulating the burning rate based on the oxidation reaction. As the aliphatic polyether a bifunctional or polyfunctional compound having a particular structure is employed. As the curing agent a polyfunctional isocyanate compound or polyisocyanate compound is employed. As the oxidizer a perchlorate such as ammonium perchlorate is preferred, and as a burning rate modifier an iron compound such as ferric oxide is preferred.
