Electric Aircraft Propulsion [PDF]
Abstract This paper presents the state of the art in electric aircraft propulsion systems. The necessary reduction of greenhouse gas emissions on the global scale forces aviation engineers to search for ‘green’ solutions. Electric aircraft propulsion is a potential and relatively intuitive choice for a reduction of emissions in flight ...
