MC1442 aging and compatibility studies
An aging and compatibility study has been conducted with the MC1442 thermal battery igniter to determine the effects of a hydrogen atmosphere on the energetic materials. Igniters were aged up to one (1) year at 70/sup 0/C in a 50/50 hydrogen/helium and also a pure helium atmosphere to simulate a 25-year aging environment at the normal thermal battery storage temperature. Functional testing with the igniter, including an all-fire Langley sensitivity format, function time and photographic flame profile measured no deviations from baseline samples. Analytical testing for changes in the energetic materials during aging measured less than 5% reaction of the nitrocellulose and no detectable reaction of the LMNR/KC10/sub 3/ ignition mixture. The hydrogen atmosphere reacted with the nitrocellulose at a rate greater than two times that observed for the helium-aged igniters. Since igniter performance was not affected by aging in hydrogen or helium, it was concluded that the MC1442 would function reliably in a thermal battery environment containing hydrogen.
