Abstract
High explosives suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms, used as safe and arm devices, are prepared from slurries of crystalline energetic materials including organic liquid and applied using various methods. These methods include swipe loading, pressure loading and syringe loading. The organic liquid serves as a volatile mobile phase in the slurry so as to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the loading hole.
Claims22
A method for loading crystalline energetic material into a small volume loading hole of a fixture of a MEMs safety and arming device fabricated on a die approximately one square centimeter or less in area, said method comprising the steps of:
- preparing a slurry or paste containing the crystalline energetic material;
- loading the slurry or paste containing the crystalline energetic material into the loading of the fixture of the explosive device wherein the crystalline energetic material comprises high explosive material and an organic liquid for the shiny or paste.
