PREDICTIVE TECHNIQUES FOR AIRBAG INFLATOR EXIT PROPERTIES

This paper presents techniques for pyrotechnic inflators and for hybrid inflators. Semi-empirical methods are presented which use closed test tank and inflator combustion pressure data in conjunction with ballistic and thermodynamic equations to predict the inflator mass flux and exit gas temperatures. Analytic methods are presented that use ballistic, gas dynamic and thermodynamic equations to predict the gas exit properties of an inflator. These analytic methods are useful as design tools when performance predictions are needed. Results from all methods are compared to experimental data where data are available. For the covering abstract of the conference see IRRD 875833.
