During 8 months 12 ETH mechanical and electrical engineering students, will develop a 4-seater electrical airplane with modular batterry system, based on a Sling TSi. The ETH focus project will start in Sept. 2020 and end in May 2021.
Foundational research on e-aviationFor 5 months the two ETH mechanical engineering students Nicolai Solenthaler (1) and Alexander Weiser (2) researched the electric aviation cooperation with «Deutsches Zentrum für Luft- und Raumfahrt e.V.» (DLR) and further partners. Within their bachelor’s thesis they designed a 6-seater electric aircraft concept with innovative drive train and a range of up to 500 km
Analysis of viable aircrafts
For the development of a real plane multiple aircrafts were analysed. Since the beginning the 4-seater Sling TSi by «Sling Aircraft» from South Africa was among the favourites. The first Skype-Call with Sling Aircraft confirmed mutual interest and ended in a «Letter of Intent», the base for a feasibility study.
Based on the Sling TSi an optimised electrified version «e-Sling» was designed. It was apparent that for maximal range the wingspan of 9.5 m had to be increased by roughly 1 m. Further adaptions of the Sling TSi for the electric motor and for the wings to place the modular and cooled batteries are necessary.
