| Abstract: |
A solid propellant gas generator is essentially an airbag inflator without a bag. That is, the gas generated is discharged directly into ambience rather than into a bag. A typical solid propellant gas generator consists of solid propellant tablets which will, upon ignition, rapidly react to generate gas-phase combustion products and particulates, an ignitor to initiate the combustion of the propellant, a filter system to prevent or minimize the release of the particulates from the combustion reactions into the ambience, a heat transfer mechanism (normally the filter itself) to cool the high temperature combustion gas before being discharged into the ambience, and an exhaust mechanism to disperse the gas efficiently. In this article, an overview of the current status on solid propellant gas generators will be discussed, and potential areas for future research will be suggested. |
