Abstract:

Electrically initiated pyrotechnic training simulators fielded in training operations are exposed to severe electromagnetic radiation environments which with a growing reliance on the frequency spectrum, are expected to increase in severity. Unfortunately, beyond intended purpose, this electromagnetic radiation energy behaves as an ignition stimuli for electrically initiated pyrotechnic simulators using commercially produced bridge wire electric match igniters. In the configuration where the ignition cable and igniter element remain unprotected, the electromagnetic radiation energy may induce undesirable electrical currents in the pyrotechnic munition ignition system, which in turn, pass through and heat the bridge wire sufficiently to cause inadvertent igniter function and injury producing accidents. The effectiveness of ferrite cable used in place of conventional cable to combat hostile electromagnetic radiation environments was evaluated by testing retrofitted simulators in accordance with MIL-STD-464, Department of Defense Interface Standard, Electromagnetic Environmental Effects Requirements for Systems. Results have been plotted and analyzed as a function of no-fire field intensity versus frequency for ferrite and conventional non-ferrite cable configuration for comparative purposes. It has been demonstrated that the application of ferrite cable in place of conventional cable for pyrotechnic simulator ignition systems has proven an effective means in reducing vulnerability to electromagnetic radiation stimuli.
