Ground Power Unit

A Electric-powered Ground Power Unit (GPU) in aviation is a critical piece of equipment used to provide electrical power to an aircraft while it is on the ground. This allows the aircraft to operate its systems without relying on its own engines, which is especially useful during boarding, maintenance, or when the engines are not running. Here’s a closer look at the key aspects of GPUs:

Key Functions

  • Electrical Power Supply
    GPUs deliver the necessary electrical power for aircraft systems, including lights, avionics, and climate control, enabling pre-flight checks and passenger boarding.
  • Battery Charging
    They can also be used to charge the aircraft’s batteries when needed.
  • Engine Start Assistance
    Some GPUs provide high-power outputs to assist with starting the aircraft engines.

Types of Ground Power Units

  • Mobile GPUs
    These are transportable units that can be moved around the airport or hangar as needed. They often have wheels and are powered by diesel or electric engines.
  • Fixed GPUs
    Installed permanently at gates or maintenance areas, these units provide a continuous power supply without the need for transportation.

Key Features

  • Voltage Compatibility
    Most GPUs provide power at standard voltages, such as 28 volts DC for smaller aircraft or 400 Hz AC for larger commercial jets.
  • Safety Features
    They are equipped with circuit breakers, connectors, and other safety mechanisms to prevent overloads and ensure safe operation.
  • Durability
    Designed to withstand various weather conditions and rough handling typically found in airport environments.

Benefits

  • Carbon Footprint
    Our renewable energy source reduce emissions and noise pollution. These units are designed with state-of-the-art technology, ensuring precise power output and minimal waste.
  • Fuel Efficiency
    By using ground power instead of running aircraft engines, airlines save fuel and reduce emissions.
  • Reduced Noise
    GPUs help minimize noise pollution around airports by reducing the need for engine operation during ground operations.
  • Operational Efficiency
    Ground power allows for quicker turnarounds as aircraft systems can be powered up while still at the gate.

Overall, Ground Power Units are essential for the efficient and safe operation of aircraft on the ground, contributing to both operational efficiency and environmental sustainability in the aviation industry.
