Abstract
A failure detection mechanism for a geared rotary actuator having plural output stages. Each output stage has a planetary gearing set and the failure detection mechanism senses relative movement between planet gear shafts of adjacent planetary gearing sets when there is normal drive through one planetary gearing set and a back-drive through the other. The failure detection mechanism includes structure operable when a failure is sensed to either prevent further drive through the geared rotary actuator, or to activate mechanism to signal a pilot of an airplane that the failure has occurred.
