Safety Driven Design & Sizing of a Multirotor VTOL Powertrain for Continued Safe Passenger Air Transport

Kurzfassung

Within the DLR-internal project HorizonUAM, which encompasses research related to numerous UAM topics, a safe propulsion system concept for a multirotor intra-city eVTOL vehicle used for passenger transportation in the Urban Air Mobility context was developed. This presentation aims to provide an overview about the safety driven design process and its sizing results. Using a model-based systems engineering approach the propulsion system is designed and sized based on the concept of operations requirements, contingency capability for failure conditions, EASA SC-VTOL certification requirements using the safety assessment method ARP 4761 and the thermal management requirements.
