Thermal-Sprayed Thin-Film Electrode Production for Thermal Batteries

Triton Systems, Inc (TSI) has teamed with United Defense Limited Partnership (UDLP) to use a proprietary diffusion bonding technology developed by TSI in Phase I to integrate advanced Aluminum Matrix Composites (AMC) as a structural jacket for the AdvancedGun System (AGS) barrel. The AMC structural jacket enables the AGS gun system to meet Navy mission requirements of high rate and increased volume of fire, and increased muzzle velocity, by taking maximum advantage of active cooling in the AGS barrel. Thehigh thermal conductivity and high strength AMC increases the life of large caliber gun barrels by reducing barrel bore temperature by a factor of two through its innate high thermal conductivity, and by reducing thermally induced barrel stress by a factorof four. Decreasing bore temperature directly reduces bore wear, the primary cause of barrel failure. Reduction of thermally induced stress directly increases the fatigue limit of the barrel, which is the secondary cause of barrel failure.The proposed program will develop the manufacturing techniques to fabricate the AMC structural jacket for the AGS in a cost-effective manner. Material properties specific to the AGS operating environment will be determined and AGS barrel life cycle costswill be predicted.
