Fuel Saving and Energy Efficiency in the Aviation Catering Systems Using Phase Change Materials (PCMs)
Year: 2025
Type: article
Abstract: This study investigates the application of Phase Change Materials (PCMs) for enhancing fuel efficiency and energy management in aviation catering systems. Recognizing the challenges posed by conventional heating and cooling methods in aircraft, we explored the use of polymeric and composite PCMs as sustainable alternatives. A series of experimental tests were conducted on a standard aircraft trolley, simulating in-flight conditions, to evaluate the thermal performance of PCMs for both cooling and heating applications. Results demonstrated that PCMs maintained optimal food storage temperatures more effectively and for longer durations compared to traditional dry ice and mechanical chillers, achieving cooling periods of over 7 hours and heating above 60 °C for over 6 hours. Implementing PCM technology offers multiple benefits, including significant weight reduction, lower marginal fuel burn, decreased greenhouse gas emissions, and enhanced operational efficiency. The findings support the feasibility of adopting PCMs in aviation catering logistics, promising economic advantages and environmental sustainability. Further work on full economic feasibility analysis is underway.
