Research Title: Numerical Simulation of Complex Turbulent Flows
Research Description: Aircraft are not rigid, but aeroelastic structures. This means that they are susceptible to an in-flight phenomenon known as flutter. Flutter is an aerodynamically induced vibration of the wing, tail or other part of the aircraft, which can result in complete structural failure. Of particular interest are the Australian designed and built General Aircraft Factory (GAF) Nomad N22 and N24 aircraft. The Nomad is a twin-turboprop utility aircraft, originally designed primarily as a short-take-off and landing (STOL) utility aircraft for short/medium-range transportation. The flaperon configuration, unique to the Nomad aircraft, has been identified as the cause of the low-speed flutter problem. The aim of this PhD research project is to attain a better understanding of the development of low-speed flutter for wings of flaperon configuration. This will involve creating grid generation codes and solvers for the Euler and Navier-Stokes equations, coupled with an appropriate turbulent model.

Research Title: A Methodology for Determining Limits Applied to Inductive Wear Debris Sensors
Supervisors: Prof. Sylvester Abanteriba (RMIT SAMME, primary supervisor), Dr Eddie Ly (RMIT SMGS, second supervisor), Dr David Forrester (DSTO Melbourne, research consultant, Mr Andreas Pelz (Rolls Royce, Deutschland, research consultant)
Research Description: The presence of wear debris in lubricating oil systems can be a valuable indicator of incipient failure of important dynamic components such as gears, bearings and shafts. Traditionally, wear debris has been detected by the laboratory analysis of routine oil samples, inspection of magnetic chip detectors or the analysis of filter elements, all of which have significant limitations. Recently, in-line inductive wear debris sensors have been developed commercially that can be installed in the scavenge oil lines of a lubricating oil system to detect wear debris in near-real time. These sensors have found some application in the wind power, aviation and general industrial sectors. One important aspect that has been missing in relation to these sensors is a validated and logical methodology for setting appropriate limits. As with all condition monitoring techniques, if no meaningful limits are applied then the program is likely to degenerate into a data collecting exercise potentially resulting in incipient failures being undetected. The proposed research would develop and investigate several novel methodologies associated with establishing and applying wear debris limits specifically for application to in-line inductive wear debris sensors. Additionally, validation of the methods will be attempted using experimental data derived from full scale gearbox test rigs. Finally, a method for modifying the derived limits based on the consequences of failure will be developed.
