Abstract

The electric aircraft concept is recently gaining interest in the industry, due to environmental and economic reasons. Recent research shows that More Electric Aircraft applications may provide around a 20% decrease in CO2 and NOx emissions, a 50% decrease in noise, and a 20% reduction in fuel consumption compared to the previous conventional version of the same aircraft manufacturer. Considering that civil aviation is responsible for over 2% of all man-made emissions, any improvement is important in this area. Electric power seems an important player in achieving the goals of reducing emissions. This paper reviews the trend of electric energy use in aviation and the development of the definition of electric aircraft in the literature. It is seen that electric energy use is gaining great interest parallel to the achievements in electric energy storage and management. This paper presents the key technological changes that made it possible to use electric energy in aircraft propulsion and systems and discusses the future challenges for further electrification of aviation.
