After one failure and a partial success at instrumenting the aft warhead cases of a hard structure munition (HSM) weapon, we were able to develop instrumentation to record dynamic data in a hostile environment. The environments in which we recorded were the detonation of 100 lb of explosive and the impacting of 15,000 lb of concrete on the instrumented aft warhead case. The case was instrumented primarily with strain gages and accelerometers. Maximum strains were generally less than 10,000 ..mu..in./in.; accelerations were generally 100,000 g. An isolated recording system was developed that was immune to external noise sources; transducers were evaluated at anticipated maximum values. Parameters other than aft warhead cases were also measured. (auth)
