1. 5 Steps to Heaven ? A Rolls-Royce Perspective

2. 2 ? 2008 Rolls-Royce plc

3. 3 ? 2008 Rolls-Royce plc Rolls-Royce?s four markets

4. 4 ? 2008 Rolls-Royce plc Rolls-Royce Group plc - 2007

5. 5 ? 2008 Rolls-Royce plc Video: ?New Thinking, Joined Up Thinking'

13. 13 ? 2008 Rolls-Royce plc Legacy data is largely unstructured and is captured and stored in a variety of ways. Development of ontologies for hardware description, failure mechanism etc. allow us to make sense of unstructured legacy data. K-Search provides a means of interrogating legacy data and presenting structured search results back to the user K-Search is a learning system that builds an understanding of document content such that after the ?learning process? >95% rate of correct automated document content classification can be achieved.

15. 15 ? 2008 Rolls-Royce plc Marine Off-shore Supply and Service Vessel

16. 16 ? 2008 Rolls-Royce plc

17. 17 ? 2008 Rolls-Royce plc Leading edge burns away over time Causes: cooling blockage, oxidation Condition that typically occurs on high time engines (primarily on-condition engines) Causes increased stress on the 1st stage blade leading to high cycle fatigue (secondary damage) Turbine blade fracture leads to in flight shut down and a 2x shop visit cost

18. 18 ? 2008 Rolls-Royce plc Vane distress showed up as performance changes. Data fusion allows clear signature to be set Fuel flow, turbine temp, pressure & speed 50 hour window after detection with 96% confidence of preventing HPT blade failures Allows time to schedule removal Thresholds set to balance false positives and false negatives Relatively small number of false alerts and false negatives

19. 19 ? 2008 Rolls-Royce plc The alternative of not having EHM for this issue Allow HPT-1 blade failures Pull engines in mod campaign Implement a 50 hr boroscope inspection interval 8 yr EHM Savings estimated at over $60M Based on mod campaign or inspections both ($$$$) Savings continue as engines age and experience vane distress

20. 20 ? 2008 Rolls-Royce plc So What?s the Problem ?

21. 21 ? 2008 Rolls-Royce plc Quantitative User friendly Intelligent Collection of Knowledge (QUICK)

24. 24 ? 2008 Rolls-Royce plc Example results ? 826 tests

25. 25 ? 2008 Rolls-Royce plc

26. 26 ? 2008 Rolls-Royce plc Different perspectives ? system boundaries

27. 27 ? 2008 Rolls-Royce plc EHM Intelligence Dichotomy Fleet centred view - the realisation of full value by having an accurate, real time fleet view of the state of all assets Platform centric view - Devolving EHM intelligence to the local platform to compensate for: limitations in communicating with a central information hub (a lack of infrastructure and capacity) Requirements for assets to operate and be maintained autonomously Concerns for data privacy and IPR
