Abstract:

To develop green aviation is the common understanding of the society of human beings and new energy electric aircraft provides a bright technological approach to achieve a complete green aviation.The impacts of aviation on environment,applications of electricity in airplane and development history of electric aircraft have been briefly described at the beginning of this paper.The energy classification and the electric propulsion system with its overall efficiency of new energy powered electric aircraft are more deeply studied.Focusing on manned light sport aircraft,the development status,characteristics and energy demand of electric airplane are analyzed.Through researches of range and ultimate range of manned electric aircraft with energy of battery,challenges or key technologies faced by the electric aircraft,which include battery energy density upgrade and performance improvement,high lift-to-drag ratio aerodynamic aircraft design,low-cost lightweight efficient composite aircraft structure design and manufacture,high efficiency electric propulsion system design and integration,are put forward.Finally,the recommendations of striving to develop electric aircraft and future research directions in this field are provided.

Key words: green aviation, electric aircraft, electric propulsion system, new energy, range, technical challenge
