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

摘要

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.

1. A method of real-time rotor system condition detection comprising:
measuring a set of loads to obtain measured signals; virtually monitoring the set of loads to obtain estimated signals, the virtual monitoring accomplished through use of an empirical load model representing a real-time environment; subtracting the estimated signals from the measured signals to obtain residuals; comparing the residuals to a categorical model; and identifying a categorical output representative of a rotor system condition within the categorical model.
