A Ground Power Unit (GPU) is an essential piece of equipment in the aviation industry, providing power to aircraft while they are on the ground. This external power source allows aircraft to operate their electrical systems, such as lighting, air conditioning, and avionics, without needing to use their own engines. This capability is crucial because it reduces wear and tear on the engine, saves fuel, and minimizes carbon emissions while the airplane or helicopter is stationary.
GPUs come in various forms, including mobile units which can be towed to wherever they are needed on the airport apron, and fixed electrical ground power which is installed at airport gates. They can provide power in different voltages and types, typically delivering 28V DC for smaller aircraft and 115V 400Hz AC for larger commercial jets, matching the onboard electrical system requirements.
The need for GPUs arises from the practical limitations of using an aircraft’s engines for ground operations. Running an aircraft’s engines solely to power onboard systems is inefficient and costly, not to mention the environmental impact of increased fuel burn and emissions. By using a GPU, both airplanes and helicopters can maintain essential functions without the engine running, leading to operational savings, reduced environmental footprint, and improved safety on the ground.
3 Facts About Ground Power Units:
- Variety of Power Sources: GPUs can be powered in multiple ways, including plugging into a standard 3-phase electrical system, large battery packs, gasoline or diesel engines, and even small turbine engines that provide both bleed air for engine starting and electrical power for the aircraft. This variety ensures that GPUs can be tailored to meet the specific needs of different models and operational environments.
- Types of GPUs: There are primarily two types of aircraft ground power units —mobile and fixed. Mobile GPUs are self-contained units mounted on wheels, making them easily transportable to different aircraft across the tarmac. These are common in airports with a diverse range of aircraft. Fixed GPUs, on the other hand, are stationary units installed at specific gates or maintenance areas, suitable for airports with a consistent fleet of aircraft.
- Electrical Compatibility and Efficiency: Ground power units are designed to meet the specific electrical system requirements of aircraft, which generally operate on either a direct current (DC) system for smaller jets and turboprops or an alternating current (AC) electrical system, typically in the 400 Hz band, for larger business jets and airliners. This compatibility is crucial for the efficient operation of the airplane’s or helicopter’s systems while on the ground, ensuring that all onboard systems, from lighting to avionics, can run without the aircraft’s engines.
