RESEARCH AND DEVELOPMENT LEADING TO PERFECTION OF INSTRUMENTATION OF ELECTRO-EXPLOSIVE DEVICES
Abstract
Efforts are being devoted toward the development of a good squib simulator or instrumented electro-explosive device. This req ir of the electro-explosive device. Laboratory equipment to measure these characteristics is needed so that the instrumented EED can be tested continually as it is developed. For that reason, equipment like the precision Wheatstone bridge has been built to measure average bridge wire temperature. The bridge has been used to obtain thermal characteristics of EED's with and without instrumentation and to provide information pertaining to s precise knowledge of thermal and rf characteristics of the electro-explosive device. Laboratory equipment to measure these characteristics is needed so that the instrumented EED can be tested continually as it is developed. For that reason, equipment like the precision Wheatstone bridge has been built to measure average bridge wire temperature. The bridge has been used to obtain thermal characteristics of EED's with and without instrumentation and to provide information pertaining to heat transfer mechanisms from bridge wire to sensor. ments on the Mk 1 squib and Mk 2 ignition element at uhf and microwave frequencies are given. Use of Wheatstone bridge techniques to measure average squib bridge wire temperature rise caused by uhf and microwave excitati ns is described and preliminary re lts are presented. (Author)
