In 2019 the European Aviation Environmental Report stated showed a relative increase in CO2 emissions of 16% compared to 2005 to 2017. It also stated that an increase of 42% is expected according to current models. Aviation is thus a big sector of the global warming problem. The solution to this is to go full electric. There are already more...

Various research initiatives in hybrid-electric/sustainable aviation typically address only a single vehicle or single vehicle class. However, novel propulsion and energy solutions can be expected to be differently applied in different vehicle classes. The objective of the EU funded research project CHYLA (Credible HYbrid eLectric Aircraft) is...

In this thesis, a closer look will be taken into the design of a propulsion system of an eVTOL (electric Vertical Take-off and Landing aircraft). The primary goal of the eVTOL is to maximize the payload for a given maximum take-off weight and the eVTOL has to go into service in 2030. To make an as light weight as possible propulsion system, an...
