Estimation of the thermal characteristics of a bridgewire environment by an electrothermal response test

OSTI ID:7356596
The electrothermal response of an electroexplosive device is determined by applying a subcritical square wave current pulse to the bridgewire and monitoring the resultant temperature excursion. The temperature profile, thus obtained, can be utilized with a mathematical model called the ''Probe Method'' for approximating thermal properties. It is possible to estimate the thermal conductivity and specific heat of the pyrotechnic and the thermal contact conductance at the bridgewire/pyrotechnic interface by this technique.
