Auxiliary Power Units

NPS Technology Focus Areas: Small Engines, Reformation/Fuel Cells and Robotic Power. Mission goals for each focus area: High power density engine APU that can provide up to 45 kWe auxiliary power to meet increasing onboard vehicle power demands without reducing mobility. Silent Watch (undetectable at 50m) through the use of a fuel cell based APU that power mission equipment with main engine off while the vehicle is stationary with reduced acoustic and thermal signature. Small UGV power through small engine and fuel cell based solutions that can extend the mission duration and range of UGVs, reducing risk to soldiers.
