Sistema, control y prototipo eVTOL
, 2022 [EN] Nowadays, the increase in air pollution and the constant obstruction of conventional roads has led to the need to look for a solution beyond the manufacture of electric cars (as they cause more congestion on these roads). In addition to these inconveniences, there is a daily need for movement in cities.

eVTOL Koncept för Stadstransport
, 2019 Målet med detta kandidatexamensarbete inom flygteknik är att konceptuellt konstruera ett elektriskt flygplan för år 2030. Uppdragsprofilen är att flyga i storstadsområden och dra nytta av eVTOL vilket innebär att det startar och landar vertikalt likt en helikopter men övergår till snabb och effektiv marschflygning likt ett vanligt flygplan, allt helt ...
