OSTI ID:5848567
The predicted ignition behavior of a hot-wire initiated pyrotechnic device, as obtained from simple numerical models, is presented. The models are based on the heat diffusion equation with temperature dependent properties. The predictions of the model for the short-term responses of a specific pyrotechnic device are consistent with experimental results. The predictions of the long-term response differ significantly from experimental data. The causes of this difference are discussed, and a parametric study of the variables which have an effect on the ignition process is presented.
