Title: Jim Austin, University of York


1
Grid-based on-line aeroengine diagnostics The
DAME pilot project
  • Jim Austin, University of York

2
The Problem
  • Information is being gathered at growing rates at
    an international level
  • This information needs to be fully utilized
  • Technology is needed to integrate and exploit the
    data
  • Grid is a part of the answer to this

3
Aims
  • To build a distributed, Grid based, diagnostic
    maintenance system
  • To prove the technology on a Rolls Royce
    Aeroengine diagnostic maintenance problem
  • Demonstrate the process of building a Grid based
    system
  • To deliver grid-enabled technologies that
    underpin the application

4
The Application
  • The support of engine diagnostics on a global
    scale.
