Long Endurance Compact Sonobuoy Power Source

Future long-term Anti-Submarine Warfare missions will require the use of both active and passive sonobuoys deployed for long periods of time. To enable this long-term operation, a robust and maintenance free power source is needed to provide a stable and continuous supply of electric power. In this Phase I SBIR program, Advanced Cooling Technologies, Inc. (ACT) proposes to develop a compact sonobuoy power source. ACT will leverage its experience and expertise in thermal management technologies to design this power source for both efficient conversion and deployment during operation, as well as for safe handling and transport during storage before deployment. The proposed sonobuoy power source will meet the target power requirements (5W continuous) and shelf life for safe storage. Through the Phase I and Phase II programs, ACT will develop and fabricate a prototype, which would be delivered to Navy for future testing.
