Fault Determinations in Electroexplosive Devices by Nondestructive Techniques

摘要

Several nondestructive test techniques were developed for electroexplosive devices. The bridgewire responds, when pulsed with a safe level current, by generating a characteriThe response is indicative of the electrothermal behavior of the bridgewire-explosive interface. Bridgewires generating a characteriThe response is indicative of the electrothermal behavior of the bridgewire-explosive interface. Bridgewires which deviate from the characteristic heating curve were dissected and examined to determine the cause of the abnormality. Deliberate faults were fabricated into squibs. The relationship of the specific abnormality and the fault associated with it is demonstrated. (Author)
