Low cost dynamic energy conversion systems

There are a wide variety of applications for which the mini-HEPS represents the most cost effective approach for providing electrical and/or hydraulic power. These included remote piloted vehicles (RPV), tow targets, sensors and forward area combat enhancement devices, undersea missile propulsion/power systems, telecommunication radio repeaters for uninhabited regions, communication buoys, manportable, multi-fueled power supplies, advanced missile fusing devices, and aircraft and spacecraft auxiliary power supplies. To be competitive with battery systems, the mission total energy requirements (watt-hours or equivalent) usually should exceed 5000 Wh. This total energy can be expended at higher power levels (i.e., up to 15 kW) for a short period of time (0.5 to 5 h), or for much longer total accumulated periods (5,000 to 50,000 h) at considerably lower power levels (i.e., 10 to 500 W). In general, the higher the total mission energy requirements, the potentially more cost effective the mini-HEPS becomes. The system and its applications are briefly described
