MTVR Auxiliary Power Unit - 6 - 10 kW

The APU (6 - 10 kW) is a major subassembly to the MTVR which is managed by the Program Manager, Medium and Heavy Tactical Vehicle (PM-M&HTV) and Program Executive Office - Land Systems (PEO-LS).

The APU will be integrated onto the chassis of the MTVR truck to provide electrical power for on-board MTVR electrical functions and provide power to ground equipment. The APU shall be integrated on an AMK-27 MTVR with all Government Furnished Equipment (GFE) assembled on the vehicle.

The APU will consist of:

1) Prime Mover,

2) Electrical control system with Control Panel,

3) Generator bolted to prime mover,

4) APU mounting bracketry with motor mounts,

5) Air Intake plumbing with air filter and pre-cleaner,

5) Exhaust plumbing,

6) Fuel/Power (FP) Interface Plate

7) Electrical cabling

The APU will generate and transmit power to the FP interface plate and provide circuit protection against reversed polarity, over voltage and engine over speed. The APU shall pull fuel from the MTVR fuel tank and shall interface with the MTVR batteries for starter power. The APU system shall include a control panel mounted inside the MTVR cab which allows the vehicle operator to utilize the APU from inside the MTVR cab.

The MTVR is the largest consumer of fuel on the battlefield and the integration of an APU shall reduce fuel consumption by allowing the operators to shut off the main engine during idle times. The APU shall provide power to the vehicle electrical functions and ground equipment during static operations. The APU can also be used in dynamic operations where power is required to energize electrical equipment on the MTVR bed. The APU shall provide the following capabilities:

1) Reduce fuel consumption during high idle times

2) Provide electrical power to on-board equipment

3) Provide power to ground equipment

4) Provide power in dynamic operations to energize equipment on MTVR bed
