Abstract
A gas generator for a missile includes a propellant grain, inhibitor, internal insulation, case forward and aft closures, external insulation, igniters and a gas outlet assembly. The general steps for manufacturing the gas generator are to fabricate the components and assemble the case including the external and internal insulation. The cylindrical inhibitor is then attached to the forward closure to form a cavity into which the propellant is cast forming a sleeve around it when assembled. This propellant grain assembly is then inserted into the case, and the forward closure, igniter and gas outlet assembly are then attached to the case to form a complete gas generator. When the gas generator is ignited, the propellant is consumed by burning the solid material into hot gases which escape through the gas outlet assembly. The propellant contains its own fuel and oxidizers to provide the necessary energy.
