Abstract :
A design for a 180 kW, 5 minute thermal battery was developed. Exploratory work was completed and a 45 kW module was constructed and tested. The module delivered 43 kW of power at 60 s and 37 kW at 300 s. The specific power was 8.97 kW/kg for the first pulse and 7.7 kW/kg for the last pulse. The module weight was 4.792 kg. The test load used limited the power output. This module test proved the feasibility of using a thermal battery to meet an 8 kW/kg requirement for a 180 kW, 5 minute power supply. The module was 12 inches tall and 4 inches in diameter. Four modules would be used in series to meet the 180 kW requirement
