Integrated Power Generation for Small Unmanned Vehicles

This program will improve the size, weight and efficiency of power generators by integrating a lightweight, high efficiency alternator with a quiet, fuel efficient and high power density heavy fuel engine. It will be capable of meeting DoD needs for reliable and efficient propulsion and power systems for unmanned aircraft, ground and maritime systems. The electrical power source will use a proprietary, compact and very high power-to-weight alternator using rare earth permanent magnets. It is scalable from 0.5 to 15 kW and larger. This electrical power source could also be adapted to other conventional engines if desired. The alternator will be fully integrated with an internally supercharged Migrating Combustion Chamber (MCC) engine. Microprocessor controls will provide for load following and stabilized power at varying loads. Electronic controls will allow the use of the alternator for starting the engine. The MCC engine’s mechanism and cycle of operation allow it to operate on low octane fuels like diesel and JP-8 without auto-ignition, detonation or wet stacking. This engine provides full expansion of the combustion gases inside the engine which increases efficiency and produces a very quiet, cool exhaust. The MCC engine is scalable from 2 HP to over 200 HP.
