Batteridrevne flyvemaskiner
Verdens største flyproducenter er i gang med at udvikle elektriske fly. I første omgang som hybrid-fly. Men på længere sigt vil kortere kommercielle ruter kunne betjenes med 100 procent eldrevne passagerfly.
Korte afstande gør Danmark til det ideelle sted for helt eller delvist elektriske fly. Dansk luftfartsdirektør håber, at det kommer til at ske inden for de næste 20 år.
El er på vej ind i flyindustrien. Men før det virkelig rykker, skal batterikapaciteten tredobles. De første hybridfly til kommerciel luftfart vil sandsynligvis komme i luften i 2035.
Med 25 ton batterier om bord vil Wright Electric sende fly med 150 passagerer ud på en elektrisk flyvetur. Men hvis batterierne ikke bliver meget bedre, kunne løsningen være et hybridfly.
Med batterier til at drive fly får flyingeniører en række helt nye muligheder i motor- og vingedesign. Men batterierne er stadig for tunge. Nasa regner med fem gange mindre energiforbrug i testfly.

Erik Schaltz
Erik Schaltz received the MSc and PhD degrees in electrical engineering from the Department of Energy, Aalborg University, Aalborg, Denmark, in 2005 and 2010, respectively. From 2009 to 2012, he has been an Assistant Professor and since 2012, he has been an Associate Professor. Both positions also at the Department of Energy, Aalborg University. At the Department, he is the leader of the research group in E-mobility and Drives and the vice leader of the Batteries research group. He is a guest and associate editor in several journals related to batteries and e-mobility and he is also a board member of the Danish Battery Society. His research interests include the usage of power electronics, electric machines, fuel cells, batteries, ultracapacitors, etc. as power train in various applications like electric vehicles, industrial machinery, and heavy-duty systems. In addition, he is also focused on battery state-estimation, management (electric and thermal), and modelling (electric, thermal, and lifetime) of battery cells and packs.
