‘Causality’ in in-service information and design actions

Research output: Contribution to conferencePaper, not in proceeding


In the global market of air transport, integration of products and services is now seen as being necessary for the long-term success of engine manufacturers. This paper describes research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. Our collaborating aerospace company now offers TotalCareTM contracts, under which it leases engines to airlines while remaining responsible for their maintenance. The aims of our ongoing research are to: (1) understand the current flows of in-service information to designers; (2) understand the in-service information requirements of designers; (3) develop, based on this understanding, the most appropriate theories and methods to support designers in their new task. The work presented in this paper aims at understanding the use of in-service information in a design task by examining the executed design changes, and the rationale behind these changes. In an attempt to address this aim, a case study involving the redesign of the ‘burner seal’ of an aero engine, is used. The redesign is based on the in-service experience of the existing burner seal.
