A COOLING CURVE GENERATOR AND ITS APPLICATION TO ELECTRO-EXPLOSIVE DEVICE STUDIES
Abstract
The thermal parameters of the bridge wire of an electro-explosive device (EED) can be evaluated by studying the cooling curve of the bridge wire after a temperature excursion. A generator capable of rapidly heating the bridge wire of an EED and then presenting the cooling curve trace on an oscilloscope is described. The resistance excursion can be related to the heat capacity, and the exponential cooling is a measure of the thermal time constant. The theory and design together with typical observations are presented. (Author)
