Ground Mobile Auxiliary Power Units for Silent Watch Operations (APU)

Silent high peak power sustained over a long duration when needed

Until now electrical power has been supplied by the vehicle main engine's generator. Since this is very inefficient, particularly when engine is idling, there is an increasing need for an auxiliary power unit (APU) that can feed subsystems with high peak power, and sustained over a long duration when needed. Examples of subsystems are air condition system, observation equipment, fire control systems, and possibly a remote weapon systems.

The APU has been developed to provide reliable power and best solution for space/weight constraints, and the operational requirements of the vehicle platform.
