ABSTRACT:
A hot gas control system includes a pressure vessel defining a chamber in which is disposed a body of solid propellant material that has a leading portion and a trailing portion. A first layer of the body of solid propellant material extends between the leading portion and an intermediate region of the body of solid propellant material, and a second layer extends between the intermediate region and the trailing portion of the body of solid propellant material. The first layer is composed of a first propellant composition that produces a relatively clean gas, and the second layer is composed of a second propellant composition that produces a relatively less clean gas. The body of solid propellant is arranged to burn within the chamber from the leading portion toward the trailing portion and thereby produce a quantity of gas that passes through an outlet port to a ducting path, the first layer having a thickness sufficient to produce enough relatively clean gas to preheat the ducting structure and thereby inhibit contaminant accumulation due to the withdrawal of heat from the less clean gas.
