Abstract:

The purpose of this project is to develop improved gas generators to activate zinc-silver oxide batteries employing the Signal Corps metal-tube electrolyte reservoir activating system. The results of the propellant investigation indicated that one commercial propellant, B. F. Goodrich C-501, and a Unidynamics formulation N-1825B, exhibited the most satisfactory thermal stability and reproducible gas output and pressure-vs-time characteristics after conditioning at 300 deg F for 168 hours. However, N-1825B propellant was selected for use in the gas generator since it is easily furnished with center perforations and exhibits a low content of hydrochloric acid in its exhaust gases. During gas generator design and development, sealed matches with delays of 0, 0.2, and 0.4 seconds were developed which provided outputs sufficient to ignite the propellant charge. In addition, the original design of the gas generators was modified to incorporate a grain trap nozzle and provide base plug end ignition. A satisfactory test fixture was fabricated for pressure-vs-time and output testing.
