SYSTEM FOR AN ACTUATOR

Abstract: a system for identifying a failure of the primary load path in an actuator. the actuator includes a screw shaft and a nut assembly moveable along the screw shaft. the nut assembly comprises a primary nut for transmitting load through the actuator along a primary load path, and a secondary nut for transmitting load through the actuator along a secondary load path. the nut assembly is configured such that, in normal operation, the secondary nut is not engaged with the screw shaft and load is transmitted through the actuator along the primary load path, and such that, upon failure of the primary load path, the secondary nut is configured to engage the screw shaft and transmit load through the actuator along the secondary load path. the system includes a strain gauge configured to be mounted to the actuator and to measure vibrations of the actuator.
