Industrial applications such as aviation systems widely suffer from a particular type of fault known as No-Fault-Fault (NFF). Term NFF points to the fact that real failure remains hidden during the general troubleshooting due to its random nature. Hence, the potential failure cannot be fixed by evaluating technicians; and of course, it profoundly adds to the maintenance costs. Read more Read less

Cause of NFF is attributed to various issues including oxidation, mechanical stresses (vibration) electromagnetic fields, poor design and bad/wrong operation. They cause various intermittency issues in; for instance, chassis, PCBs, connectors, cables and wires as the system gradually ages. The intermittent fault is a malfunction of a device or system that occurs at intervals (presenting irregularity) in a device or system that functions normally at other times. In many industrial applications such as in-line replaceable unit (LRU) of aviation systems, intermittent faults found in the power chain of a system can be cascaded into other electronic circuitry, processors, microcontrollers, and memories causing random intermittent failures.

Applicants are invited to investigate the impact of intermittency on control systems and conduct research in designing No-Fault-Found resistant control. The student will have the opportunity to work with National Instruments products including Compact-Rio and Labview in developing control systems, fault injection and emulation, collaborating with experts in the prognostics, diagnostics and condition monitoring field, as well as being part of our active and dynamic research centre at Cranfield.

The Integrated Vehicle Health Management (IVHM) Centre is a major collaborative venture at Cranfield, started in 2008, with funding from the East of England Development Agency (EEDA). IVHM is a consortium of core industrial partners, (Boeing, BAE Systems, Rolls-Royce, Meggitt, Thales, MOD and Alstom); and from EPSRC. The investment, over the first five years of operation, was approaching £10M. We are now in our eighth year of exploitation, and the Centre has grown into other sectors (rail, energy, health and agriculture), and is financially self-sustaining; many of the partners (and others) are funding Applied Research projects, and there is a growing revenue from EPSRC, TSB and EU funded work.

Cranfield Doctoral Network

Research students at Cranfield benefit from being part of a dynamic, focused and professional study environment and all become valued members of the Cranfield Doctoral Network. This network brings together both research students and staff, providing a platform for our researchers to share ideas and collaborate in a multi-disciplinary environment. It aims to encourage an effective and vibrant research culture, founded upon the diversity of activities and knowledge. A tailored programme of seminars and events, alongside our Doctoral Researchers Core Development programme (transferable skills training), provide those studying a research degree with a wealth of social and networking opportunities.
