Abstract:
Electric Vertical Take-Off and Landing (eVTOL) aircraft are considered as a solution to support urban transportation, including cargo delivery (Unmanned Aerial Vehicles, UAVs) and passenger travel (Urban Air Mobility, UAM). Over the last few years many different concepts have been derived and tested to varying levels of maturity. The race for the most efficient, safe and reliable system solution ongoing, with many new challenges in the propulsion system and energy storage technology and design space, including specifically the power electronics, electrical machine (e-machine) and transmission design and verification.This paper presents an integrated '3in1' eVTOL e-Propulsion concept that has been developed utilizing a novel, integrated, model-based system engineering (MBSE) workflow that is enabled via newly developed model-translation capabilities and software interfaces. It starts with the design of the drivetrain based on a steady-state approach with low computational effort, which is then rapidly translated into a multibody model and directly coupled to a high-fidelity behavioral model of the e-machine, the inverter and control system, to represent reaction loads with even higher fidelity. The resulting holistic model can be used for assessing performance, efficiency and robustness, including various foreseeable dynamic loads such as turbulence. It was found that this workflow was valuable in supporting the risk-reduction exercise during the development of a complex aerospace propulsion system, promoting reliability and safety engineering methodology from the outset.
