Energy Source Study Technical Report for Deployable Acoustic Projector System (DAPS)
SPARTON DEFENSE ELECTRONICS JACKSON MI
Pagination or Media Count:
Potential energy sources and energy conversion methods for the Deployable Acoustic Projector Systems DAPS were studied. Various battery systems, including primary, secondary, and reserve cells, were considered, and the use of nontraditional power sources such as fuel cells and internal combustion engines were explored. Energy conversion methods direct versus load leveling were compared on the basis of to size and weight. Direct energy conversion was viewed as an energy source batter supplying power to the load projector at peak pulse levels through a dc-to-ac inverter. Indirect conversion was viewed as a mechanical means flywheel to store energy between pulses to reduce the peak drain on the battery, fuel cell, or other energy supply. Factors considered were peak drive levels, total stored energy requirement, size, weight, system reliability, initial cost, and long-term operating cost. The best choices for energy sources appear to be the non- traditional fuel cell or the internal combustion engine, in conjunction with mechanical energy storage to load leveling.
