Abstract
The monitoring method includes the steps of: acquiring a first signal from an acceleration sensor; calculating a transform in the frequency domain of the first signal to obtain an initial sequence of samples, each of the samples having a respective amplitude and a respective frequency; processing the initial sequence of samples to obtain a final sequence of samples; calculating a sixth-order moment of the final sequence of samples; and comparing the sixth-order moment with at least one predetermined threshold to detect any vibrational irregularity in the helicopter transmission assembly.
