Part 4 GMU series mobile ground power unit
1. General Description
The GMU series Ground Multi-functional Unit for Aircraft is specially designed to simultaneously provide air-conditioning and electrical power or high pressure air. The unit can satisfy both working and maintenance demands of the system when the aircraft is parked on the airfield.
Electrical Power
The unit can simultaneously or separately provide alternating current with 400Hz and 115V, or direct current with 28.5V DC for aircraft on the airfield. It can be used for ground maintenance or jet start of the aircraft.
Air supply of the Air-Condition
● To ensure the comfortable environment for passengers, it can provide ventilation (cooling or warm air) for the aircraft when it is parked on the airfield.
● To provide the comfortable fresh air for maintenance man on the plane when the aircraft is being maintained on the airfield.
High Pressure air
The unit can provide the high pressure air, which can be used to start the jet engine.
