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.
