Abstract:

Markedly safer intermediate and first fire ignition charges were developed for the M49A1 surface, trip, flare. Both the present intermediate and first-fire formulations are sensitive to impact, frictional, and electrostatic initiation. A laboratory study was conducted to develop a substitute formulation closely matching the pressure-time profile and generated gas volume of the presently used compositions, but having significantly less sensitivity. A new formulation containing 6524101 tungstenbarium chromatepotassium perchloratevinyl alcohol acetate resin VARR met these criteria and was demonstrated to be an efficacious substitute for both the older intermediate and first-fire compositions. The new formulation was designated as DP-1886. In addition to the safety factor provided by this change, a reduction of inventory and processing costs will be realized through the use of one formulation for the two different ones currently employed.
