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 investigation will be done for the propeller length and the number of rotors, which is present on a given eVTOL design. In addition to this, different drive choices will be discussed and an optimal drive choice will be made. For this drive, a closer look will be taken in efficiency optimisation. From these parameters a design example will be given using the current state-of-the-art drive technology. In addition to this possible future drive, developments will be taken into account. 

Electric Vehicles are shaping the clean energy goals and have become the poster for climate change and the energy transition. Its not only cars that is making an impact but more importantly, micro-electric vehicles spearheading first/last mile solutions. These vehicles reduce net emissions on the environment. This market needs further literature and information to integrate and have better solutions. This thesis explored the ecosystem surrounding the micro-mobility market just to underpin the lack of literature available and the need for further research on this topic. All stakeholders were studied, vehicles were investigated, business cases were discussed and environmental impacts were approximated. The policy side to this market is very crucial to its growth and this has been highlighted in this thesis. The safety impacts indicate that the market has taken a huge hit in many countries the necessity for regulatory structure has become more integral. The vehicles will get better with time and safer, and if implemented in cleaner ways, can have a huge impact on short distance mobility space. The market is poised for growth but in the Netherlands there are many roadblocks and these need further exploration. The study concluded that these vehicles are bound to stay and grow and implementation depends on regulatory climate, enforcement of safety standards, technology standards and infrastructure. Technology trends also project better vehicles in the future. Innovation in types of implementation of shared micro-mobility is still a big question. When these factors are addressed, micro-electric mobility can grow and have a huge impact in the creation of Smart Cities and better, cleaner, more efficient mobility options.
