SOLID PROPELLANT GAS GENERATOR Abstract of the Disclosure A gas generator includes an annular hermetically sealed combustion chamber containing a charge of propellant and an initiator. The combustion chamber is enclosed within an inner housing having an annular wall supporting an annular wall of the combustion chamber. An outer housing surrounds the combustion chamber and inner housing and includes an outer annular wall spaced radially of the annular wall of the inner housing to define a plenum. The outer annular wall includes a series of radially opening exit ports. A plurality of layers of wrapped fine mesh and coarse mesh screen in the plenum filter and cool the gas from the combus- tion chamber. In one embodiment, the wall of the inner housing is provided with annular axially spaced bands of radial openings of gradually decreasing size, with the largest size openings being most axially remote from the exit ports. The annular wall of the chamber ruptures through the largest openings when the pressure in the combustion chamber reaches a predetermined limit. Should this limit be exceeded the openings of one or more of the other bands are opened to pro- vide pressure relief from the combustion chamber. In another embodiment varying size openings are intermixed. In a third embodiment, the openings are slot shaped with their open ends most axially remote and their closed ends most axially adjacent to the exit ports.
