Military service people make use of vehicles like large naval ships and aircraft that are backed up by military auxiliary power units. These devices lend power to most functions that don’t rely on propulsion or movement – these are instead handled by other sources of energy and operation. Military crews usually go about the process of testing the APU and its lending power prior to any flight and are essentially shut down during flight or movement until it is necessary to be switched back into the on position.
Military auxiliary power units provide energy for electrical systems that consume a lot of resources on their own or with add-on devices and related mechanics. Because the APUs take the workload off of main engine functions, the military is able to see cost savings when it comes to vital equipment usage. The logistics and operational cost of running such large vessels and aircraft is astronomical, but auxiliary power units can help offset the burden. They have what is called low-life cycles or LCC.
These power units can be installed onto military vehicles internally or externally depending on the required type of machine. They have a power range and an output voltage level and type based on the product. Since the military makes heavy use of air-cooled diesel engines, APUs specific to this setup is popular among contractors.
They are designed for heavy-duty operation, even in the most extreme situations. The co-generation of power and drain mitigation makes the APU a necessity with large-scale military vehicles.
