We will use our newly developed smart energetic materials to eliminate flame sensitive pyrogens and the bridge-wire connections for thermal ignition within initiators/squibs which will improve safety for Mil. Std. 1901A compliance. Unlike conventional materials, new pyrogen materials are insensitive to ignition by flame and so can not flame spread by impingement. However, new faster burning formulations and electrode materials have been developed that allow for very fast ignitions. These modifications to the way rocket motor inition is conducted using pyrogen will be fully compatible with current accident mitigation methods utilized further down the ignition train. It is our ultimate goal to simplify solid rocket motor initiation systems making them safer, smaller and less expensive new solid pyrogens as the enabling technology.
