Abstract

The preliminary design phase of a turbine rotor has an important impact on the architecture of a new engine definition, as it sets the technical envelope of the product to be designed. Additionally, preliminary design cycle times are increasingly critical in capturing business opportunities in an ever competitive environment. Improving the accuracy of the preliminary design (pre-detailed design) is also necessary as not only does it significantly reduce the overall development of an engine, but also because any mistakes made at this stage can be extremely hard to rectify.

Previously, typical pre-detail fixing design cycle time was greater due to the lack of communication between specialist owned and built software and non-optimized data management. This paper presents a way to change that by detailing a single platform Design and Analysis tool for the fixing as part of a larger pre-detailed design tool. The fixing tool created allows the user, through a single graphical user interface, to design and analyze a fixing using tools for each discipline through the integration of C.A.D. & F.E.A running in batch mode.

Apart from significantly reducing design cycle time, the fixing tool is also seeking to improve the quality of the fixings and is extremely user friendly as it provides the design engineer all the information he would need for the pre-detailed design of a fixing at his finger tips.
