An Aircraft Ground Power Unit ("AGPU") is a mobile vehicle, preferably self-propelled, on which is mounted an enclosure. Within the enclosure are a number of
subsystems, each of which provides a service required by a stationary aircraft for servicing
and diagnostic testing prior to flight. Such services include electrical power, hydraulic
power(hydraulic dc power unit), engine-start capability (bleed-air), conditioned air (hot or cold) for the aircraft's equipment recesses or interior, and
nitrogen to inflate struts and operate power tools. The control, status, configuration,
and automation of all of the subsystems contained within the enclosure are consolidated
under computer control. The enclosure and the subsystems contained therein can be
readily mounted on and dismounted from the vehicle.
This invention relates to the field of aircraft ground servicing, specifically, to the provision
of electrical, fluidic, and gaseous inputs to fixed and rotary wing aircraft at the airfield
and on the flightline. An aircraft on the ground whose engine is not functioning requires
a number of services to determine whether the aircraft is in a condition to fly or taxi.
These services include: electrical power, hydraulic power(hydraulic dc power unit), engine-start capability (bleed-air), air conditioning or heating of the aircraft's interior, and nitrogen to inflate struts
and operate power tools.
