Abstract
Methodologies to deal with electrical systems and power source failures for electric vertical takeoff and landing aircraft (eVTOL) design with distributed propulsion using multiple electric motors minimize required power source energy to perform an emergency landing procedure. Interconnecting electric loads and power sources in the 'Ring Topology' concept considers combination of electric loads and power sources in order to reduce the impact on the loss of a power source, as well as to better utilize the remaining energy of the remaining power sources if any load becomes unavailable.
