ELECTRIC AIRCRAFT - PRESENT AND FUTURE
PRODUCTION ENGINEERING ARCHIVES 23(2019), pp. 36-40
In this paper, an outlook about the present of electrical aviation is given. The relatively small energy density of current battery technologies is adequate to build usable electric car, but not suitable for elec-tric aircraft. Because of the very limited amount of energy available on-board, a couple of percent in efficiency can give significant increase in range and flight time, hence the development of more effi-cient propulsion system and E-motor is as important as the development of battery technologies. Cur-rent research results at the University of Dunaujvaros show, that building E-motors from amorphous materials is possible, and can easily increase the efficiency of high speed E-motors.
