What’s Consuming Power?
BLUE FORCE
TRACKER
Changes in the Power Approach Previous APUs were for stationary power only
| Future APUs will be used on-the-move. |
| Take the electrical load off the vehicle engine |
| Provide more power at low speeds |
General Requirements
| Operation on Tactical Fuels – DF-2, JP-8, ULSD, etc. |
| APUs will draw fuel from the vehicle fuel tank |
| NO special fuels at this time |
| Self priming, 6+ vertical feet |
| Voltage Connection – DC is the primary goal at this time, AC options are a plus. |
| APU must connect and operate with the vehicle’s existing DC bus. |
| Expect to find various battery types. |
| MIL-STD-1275 |
| Temperature Ranges |
| Full power up to 131°F |
| Start and operate at -40°F w/o external assist |
| Don’t forget Solar Loading |
| Self-cooling |
| Altitude |
| Full power up to 4,000+ ft. |
| Operation up to 12,000 ft. |
| Sand and dust filtration |
| Fully Enclosed |
| External mounting (increased vibrations) |
| No armor at this time |
| Multiple mounting options |
| Vibrations |
| Primary Roads – Paved Roads – 10% |
| Secondary Roads – Loose Gravel – 20% |
| Trails – Unimproved, seldom traveled – 30% |
| Cross County – No man-made trails – 40% |
| Noise Requirements |
| < 70 dBA @ 7 meters |
| Systems will be used for QUIET watch |
| Other Requirements |
| Local/Remote control |
| Long life (5000+ hours) |
| Quick start capable (<5 minutes) |
| Various electromagnetic interference requirements |
Power Range
| NO SET POWER REQUIREMENT |
| APUs are needed for various platforms with differing needs. |
| Current areas of interest |
| 3 to 5 kW (DC only) |
| 10 to 15 kW (DC with AC options) |
