A Comparative Study of Conventional and HybridElectric Propulsion Systems for Sustainable AircraftDesign

Abstract

The aviation industry is a significant contributor to global carbon emissions, prompting the
exploration of more sustainable aircraft propulsion systems. This paper presents a comparative
study of conventional and hybrid electric propulsion systems for sustainable aircraft design. The
study examines the technical, environmental, economic, and operational factors associated with
both propulsion systems. By reviewing current literature, the study highlights the benefits and
challenges of hybrid electric propulsion in comparison to traditional jet engines. The findings
suggest that hybrid systems may offer a promising pathway to reducing aviation's carbon
footprint, but challenges related to energy density, infrastructure, and initial investment remain
significant barriers.
