ABSTRACT:
A gas generating system (10) includes a tubular outer housing (12) having a longitudinal axis (L) and one or more apertures (12d) formed therealong to enable fluid communication between an interior of the outer housing and an exterior of the outer housing. A tubular inner housing (70) is positioned within the interior of the outer housing (12). The inner housing (70) includes one or more apertures (70d) formed therealong to enable fluid communication between an interior of the inner housing and an exterior of the inner housing. A first tubular baffle (80) is provided for cooling and regulating a flow of gas produced by the gas generating system (10). The first baffle (80) has a plurality of corrugations (80c) formed therealong and is positioned between the inner housing (70) and the outer housing (12) to define a gas flow channel (82) extending between the first baffle (80) and the inner housing (70). The first baffle also includes an opening (80e) formed therein to enable fluid communication between the gas flow channel (82) and an exterior of the gas flow channel. The corrugations (80c) are spaced apart from the inner housing (70) to provide a corresponding plurality of constricted gas flow passages (84) extending between the corrugations (80c) and the inner housing (70). The constricted passages (84) provide alternating compression and expansion of gases flowing along the gas flow channel (82), thereby facilitating cooling and filtration of the gases.
