                            <p>Elektrikli uçak konsepti, çevresel ve ekonomik nedenlerle son zamanlarda sanayide ilgi görmektedir. Yakın zamanda yapılan araştırmalar, Daha Fazla Elektrikli Uçak uygulamasının, aynı uçak üreticisinin önceki konvansiyonel modeline kıyasla emisyonlarda yaklaşık %20, gürültüde %50 ve yakıt tüketimlerinde %20 azalma sağlayabileceğini göstermektedir. Sivil havacılığın tüm insan kaynaklı emisyonların %2&#039;sinden fazlasından sorumlu olduğu düşünüldüğünde, bu alandaki her iyileştirme önemlidir. Elektrik, emisyonları azaltma hedeflerine ulaşmada önemli bir etken olarak görünmektedir. Bu makalede, havacılıkta elektrik enerjisi kullanım eğilimi ve literatürde elektrikli uçak tanımının gelişimi ele alınmıştır. Elektrik enerjisi depolama ve yönetimi alanındaki kazanımlara paralel olarak elektrik enerjisi kullanımının da büyük ilgi gördüğü görülmektedir. Bu makale, elektrik enerjisinin uçak tahrik ve sistemlerinde kullanılmasını mümkün kılan temel teknolojik gelişmeleri sunmakta ve havacılığın daha fazla elektrifikasyonu için gelecekteki zorlukları tartışmaktadır.</p></trans-abstract>

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.</p></abstract>
