Electrical propulsion aircraft (EPA) have been cited as the future of aviation, enabling greener, quieter, more eﬃcient aircraft. However, due to the stringent requirements surrounding aircraft certiﬁcation, these novel EPA concepts will need to demonstrate high levels of safety and reliability if electriﬁed ﬂight is ever to become a mainstream mode of passenger transportation. Therefore, robust electrical fault management (FM) is necessary to maintain critical levels of aircraft thrust and to enable high conﬁdence in the reliability and safety of future EPA designs. To date, electrical FM for EPA has been done at a ﬁrst-pass, minimal level or not at all. For electrical FM to be eﬀective, it must be integrated into the aircraft design from an early stage. This dictates that a novel approach to the design of electrical architectures for EPA is required which addresses the current uncertainty in the availability of suitable FM technologies for future EPA electrical architectures. Therefore, a ﬁrst-of-kind FM strategy map is presented which identiﬁes projections on the progression of key areas of future EPA-speciﬁc FM technology development and acts as a pre-cursor to future FM technology roadmaps. Furthermore, the FM orientated early-stage electrical architecture design methodology presented in this thesis derives feasible, FM-capable electrical architectures for a given EPA concept and captures signiﬁcant assumptions which impact the down selection process. Since any novel EPA electrical architecture will require some form of testing in hardware, a novel framework for strategic FM demonstrator development is then proposed and the FM test goals for diﬀerent levels of demonstrator are identiﬁed. This strategic development of critical aspects of FM and early integration of FM requires a portfolio of FM demonstrators and test beds for EPA and is crucial if unproven, future EPA electrical architectures are to reach high conﬁdence.
