Bearings fault detection in helicopters using frequency readjustment and cyclostationary analysis
An automated framework is introduced to deal with bearing monitoring in helicopters. The innovation rests on the proposal of the readjustment of the fault frequency. The innovation rests on a statistical estimator to allow decision making. The method is applied on data from two test-benches and from flight data.
