Using average order spectra to determine point ordering

Article scientifique 2023 Anglais

Résumé

Abstract This application used order analysis to identify the main and tail rotors of a helicopter as potential sources of high-amplitude vibration in the cabin. First, rpmfreqmap and rpmordermap were used to visualize orders. The RPM-order map provided order separation throughout the RPM range without the smearing artifacts present in the RPM-frequency map. rpmordermap was the best choice to visualize vibration components at lower RPM during the engine run-up and coast-down.
