Current aircraft propulsor designs have one engine or motor per propulsor. A failure of one engine or motor results in failure of one propulsor, and requires emergency landing. Many fatal accidents are attributed to engine failure. New configurations to increase urban mobility need high reliability for safety. To increase safety, we will develop an intelligent propulsor drivetrain enabling continued flight in the presence of motor failures. Specifically, we plan to design and build a propulsor drivetrain that adapts to motor failures to maintain constant thrust when sufficient power remains.
