Abstract: The objective of this project is to develop novel thermal battery based reserve power source solutions for the Navy Conventional Ammunition Fuzes that would meet current and future Naval ammunitions fuzing requirements. The power source must provide a nominal voltage of 5.6 V and current of 35 mA in less than 10 msec with a standard deviation of about 1ms for the first 10 seconds and 325 mA at 5.6 to 12 V for a total run time of 200 seconds with a volume of 15-20 cubic centimeter. Currently available reserve power source technologies, including thermal battery technology, are not capable of providing a power source that could satisfy these requirements. The proposed novel power source concepts are expected to provide the means to address the indicated rise time, run time and volume and power requirements. The proposed novel power sources provide the means of generating the required starting low power very rapidly to satisfy the indicated rise time and a novel thermal management technology which allows the power source to run over 200 seconds. The proposed reserve power sources can withstand very high-G firing shock and spin rates and provide a shelf life of over 20 years.
Benefits: The proposed innovative reserve power sources with fast activation and relatively long run time have a wide range of military and commercial applications. On the military side, such reserve power systems can be used to power almost any munitions, rockets and missiles. In the commercial areas, the high reliability, short rise time and very long shelf life of such reserve batteries that can withstand very harsh environments and shock loading makes them particularly suitable as an unattended backup emergency power source for powering emergency equipment and devices such as communications and medical devices, rescue beacons, etc.
