D2R: A 50 PASSANGERS ELECTRIC MOTORIZED COMMERCIAL AIRCRAFT

摘要

Today the flight industry contributes 2% of the world's carbon emissions. Till 2050rnit is expected to get up to 3%. This paper presents the solution for the problem - therndesign of a 50 passengers’ electrical motorized aircraft – D2R. Creating a newrninnovative, multi discipline and feasible design. The design must overcome challengesrnin propulsion, and so it introduces a solution of Li-Air batteries and super conductingrnmaterials. The innovative design and unfamiliar energy and propulsion systemsrnprevents us from a weight certainty, and to make up for it the aircraft is designed withrn95% of composite materials in the structure body, thus helping create highrnperformances in many function aspects. D2R is a regional aircraft which can get up torna 1000nm range because of its aspect ratio is higher than average. This paper shows therndesign process including analysis and decisions that were made. The combination ofrnelectrical propulsion and aviation is not simple, but possible and should be on the flightrnindustry agenda.
