Краткое описание

Gas generant formulations based on sodium azide have proven to be an excellent source of non-toxic, low temperature gas for automotive inflatable restraint systems. Nevertheless, non-azide compositions are desirable to minimize potential environmental releases of sodium azide mixtures. Critical characteristics of candidate non-azide compositions must be efficiently characterized, including high burning rate, breathable combustion products, low hazards, and wide temperature ballistic performance capability. Excellent results have been obtained using a high pressure, windowed, strand burner coupled with species distribution measured in the flame using Fourier Transform Infrared spectroscopy, or FTIR. Candidate formulation T-239 was characterized by these methods and found to have suitable burning rate properties and species distribution for use as an airbag gas generant. This is, in turn, is used as critical input to inflator performance simulation wherein gas phase kinetics are also modeled.
