Dančová, DominikaJanovec, Michal2020-06-302020-06-302020978-80-554-1686-1http://drepo.uniza.sk/handle/hdluniza/183The aim of this paper is to evaluate the propulsion of aircraft from the present to the future development of the aviation industry. The paper describes the negative effects on the environment, new possible solutions for drives, as well as design modifications of engines. The first chapter is focused on the current propulsion of aircraft and their basic division. Described piston and jet engines. The second and third chapters describe the propulsion of hybrid and electric aircraft. They have great potential for reducing fuel consumption in aviation, as fuel prices are constantly rising. Hybrid electric propulsion systems not only provide fuel economy benefits, but also reduce take-off noise and emissions. The final chapter is focused on the results of research into the development of hybrid and electric drives, evaluated possible assumptions of success of individual parts.skhttp://creativecommons.org/licenses/by/4.0/current aircraft propulsionharmful emissionsnoisehybrid aircraft propulsionelectric aircraft propulsionrevolutionary technologiesdevelopmentBook of proceedingshttps://doi.org/10.26552/pas.Z.2020.1.5
