In thesis I target to social-political, econo]mical and technical aspects of this kind of propulsion which have positive or negative tendency in next evolution of electric propulsion. With my mentor we assume that the main problem will be with energy density of Lithium batteries which is sixty time lower than density of comertional jet fuels. This problem we present in examples of three airplanes with different capacity and range. At the end of the thesis we presented the most interesting existing project of electrically-propelled aircraft and analyzethe main advantages of electric propulsion.enhttp://creativecommons.org/licenses/by/4.0/distributed propulsionenergy densityLi-ion battery life-cyclegreenhouse emissionsBook of proceedingshttps://doi.org/10.26552/pas.Z.2020.1.23
