Significance of output:

Following the EU FP5 ATOS project, our project partner Rolls-Royce plc. (Ian Care, Ian.Care1@rolls-royce.com) sponsored a research on friction detection using acoustic emission (AE) techniques for hybrid contacts (£5k), which have been considered for the main shaft bearings on new generation aero-engines. This paper demonstrates that AE has a potential to significantly improve the monitoring capabilities of current technologies (vibration and temperature) by providing early warnings and detecting different contact physics. This can save millions of pound for transmissions and engine manufacturers. The results have been fed into another PhD programme sponsored by GE Aviation (Dr Honor Powrie, Honor.Powrie@ge.com).
