Tribological Assessment of Exit Guide Vane Support Tabs in a Jet Engine

Exit guide vanes are critical components at the rear of the low-pressure compressor in jet engines, responsible for directing airflow to maximize efficiency. This study focuses on evaluating and characterizing wear patterns on the support tabs of an engine-run exit guide vane with the aim of improving the longevity of future designs.

In this presentation, findings from this investigation will be discussed, including the observed types of wear and the techniques employed for evaluation. Analysis methods include white light interferometry, scanning electron microscopy, elemental analysis, and x-ray photo spectroscopy.
