However, let’s explore the inner workings of EPS technology to understand how this extraordinary phenomenon occurs.
Description Of The Technology Behind Eps
The essence of an EPS is rooted in its conversion and control mechanisms. Advanced electronics guarantee:
- In order to prevent electrical hazards and establish a dependable connection with the aircraft, stringent safety protocols have been implemented.
- Power conversion involves transforming the incoming power to align with the particular voltage and frequency demands of the aircraft.
- Sophisticated controls oversee and manage the flow of power, guaranteeing optimal functionality and averting equipment overload.
How EPS Are Integrated Into Airport Infrastructure
Thorough planning is necessary when incorporating EPS. Below are the steps involved in the process:
- Engineers assess the airport structure, energy requirements, and parking arrangements in order to ascertain the most suitable positioning of equipment.
- In the process of infrastructure development, power distribution is achieved through the installation of either underground cables or overhead structures within the designated areas.
- Installation of connection points involves the use of specially crafted units that establish a secure and weather-resistant interface for delivering power to the aircraft.
Types Of External Power Systems
To address diverse requirements, there exist two primary categories of EPS. Let’s take a closer look:
Mobile Units
Mobile units are portable power systems designed to provide electricity and other essential services to aircraft in various locations, including remote areas or temporary parking spots. These units come in different forms and configurations, each tailored to specific operational needs. Here are some common types of mobile external power units:
Towable Generators
Towable generators are mobile units equipped with a generator mounted on a trailer or towable cart. These units are often used in smaller airports or remote locations where access to fixed power systems is limited. Towable generators can be easily transported and positioned near aircraft, providing them with the necessary electrical power for maintenance or turnaround operations.
The advantage of towable generators lies in their portability and flexibility. They can be quickly connected to aircraft using power cables and adapters, making them ideal for handling aircraft in diverse environments.
Ground Power Units (GPU)
Ground Power Units (GPUs) are mobile power systems specifically designed to supply electricity to parked aircraft. These units can range in size and capacity, from compact diesel-powered units to larger systems capable of supplying high voltage to multiple aircraft simultaneously. GPUs are often equipped with various output options, including AC (Alternating Current) and DC (Direct Current), to accommodate different types of aircraft.
GPUs are commonly used at airports to provide electrical power to aircraft during pre-flight preparations, maintenance checks, or while parked at remote stands. They ensure that aircraft systems remain operational without relying on internal power sources.
Battery Packs
Battery packs serve as mobile power solutions for smaller aircraft or when temporary power is needed in remote locations. These units are equipped with rechargeable batteries capable of delivering electrical power to aircraft systems. Battery packs are lightweight and portable, making them suitable for applications where conventional generators may not be practical.
Battery packs are especially useful for providing power during engine starts or avionics checks. They offer a quiet and emission-free alternative to traditional fuel-powered generators, making them environmentally friendly options for ground power supply.
Fixed Systems
Permanently installed systems, known as fixed systems, feature a network of cables and connection points that are strategically placed in designated areas. These systems offer a more streamlined and efficient solution for larger airports experiencing high volumes of traffic.
Pre-conditioned Air Units
External Power Systems (EPS) extend their functionality beyond mere power supply by incorporating pre-conditioned air units (PCA). These units not only deliver power but also circulate cool or warm air into the aircraft, swiftly achieving a pleasant cabin temperature for passengers upon arrival. This eliminates the necessity of using onboard systems for pre-conditioning, resulting in fuel savings and reduced emissions.
Benefits Of Implementing External Power Systems
EPS offers advantages that extend well beyond environmental considerations. They have the potential to greatly enhance the overall passenger experience.
