Failure mechanisms and design considerations for fault tolerant aerospace drives

This paper considers existing More Electric technologies in commercial aircraft, observing recent technologies adopted by aerospace and discussing the reasons restricting the application of other designs. Fault tolerant drives are considered, assessing where reliability may affect application in aerospace. Failure conditions and design issues are proposed which will present challenges in the evolution of laboratory prototypes to actual aerospace hardware. Results are presented from fault tolerant drives, highlighting some of these design considerations.
