In-Service Information Flows to Designers

Research output: Contribution to conferencePaper, not in proceeding


This research is triggered by the emerging ‘power by the hour’® paradigm, in which aero engines are
effectively leased to airlines, with the manufacturing company remaining responsible for their
maintenance and repair throughout their service life. By incorporating knowledge about the
performance of existing products into the design phase of new products, it is hoped to tackle some of
the in-service problems at the design stage. In the aerospace sector, it is standard design practice to
utilise the experience gained from past projects, but that from in-service has not been given sufficient
attention. In this context, the aims of our ongoing research are: (1) to understand the current flows of
in-service information to designers; (2) to understand the in-service information requirements of
designers; (3) to develop the most appropriate theories and methods to support designers in their new
task of creating engines which will perform reliably and economically throughout their service life.
This paper presents the results of the initial phase of research project and addresses the first aim of the
research. In particular, this paper investigates the various in-service information sources available to
designers, and their content. The information stored in these sources is examined to investigate its
ability to answer the designers’ questions regarding in-service information.
