A single platform D&A (Design & Analysis) tool is outlined in this paper that allows a user, through a single GUI (Graphical User Interface), to create a turbine rotor fixing as well as analyze the structural integrity of the fixing. This is done through the integration of CAD (Computer Aided Design) and FEA (Finite Element Analysis) software running in batch mode, driven by the GUI. This SPIE (Single Platform Integration Environment) captures the strength of CAD software to create a fully parameterized fixing that is able to model legacy, current designs and provides flexibility to design fixings not yet conceived. Using the automated use of FEA software through a secure and reliable gateway, stress analysis can be performed and the results displayed back to the user through the GUI. This tool provides a significant increase in quality and time savings to design a fixing when compared to the previous design methodologies. What used to take hours to design and analyze through the use of isolated specialist built and owned tools with little communication between them and non-ideal data management, now takes minutes; a reduction of up to 10 fold in the time taken.
