In this paper, the development and implementation of a novel approach for fault detection of
an aircraft auxiliary power unit (APU) has been demonstrated. The developed approach …

This paper presents a comprehensive evaluation of the near-field acoustics of an aircraft
auxiliary power unit (APU), based on experimental data acquired from an in-situ APU. The …

Acoustic emission (AE) technology is one of the most established diagnostic techniques for
rolling bearing monitoring in rotating machinery. The application of high-frequency AE for …

A journal bearing in operation is subjected to harsh and extreme conditions and may fail in a
number of different ways. The failure mechanisms involve complex tribological science. As …

Journal bearing fault diagnostics is crucial in numerous sectors where journal bearings are
extensively used to support and guide rotating shafts in machinery such as compressors …

Journal bearings are critical components for many important machines. Lubrication analysis
techniques are often not timely and cost effective for monitoring journal bearings. This …
