A method of real-time rotor fault detection includes measuring a set of loads to obtain measured signals and virtually monitoring the set of loads to obtain estimated signals. The estimated signals are subtracted from the measured signals to obtain residuals and the residuals are compared to a categorical model. A categorical output representative of a rotor fault is identified within the categorical model.

Rotor system health monitoring using shaft load measurements and virtual monitoring of loads

A system for monitoring for pushrod faults in an aircraft includes a pushrod; a sensor () mounted on the pushrod (), the sensor () wirelessly transmitting measured pushrod load data; a receiver () receiving the measured pushrod load data; a model () receiving flight data and generating a modeled pushrod load profile; and a fault detector () comparing measured pushrod load data to the modeled pushrod load profile to detect a pushrod fault.
