Abstract
Blade Diagnostics Corporation proposes to study the feasibility of developing a field mistuning tool and an associated approach for managing the mistuning problem in integrally bladed rotors (IBRs). The field inspection tool will determine the frequencies of individual blades in IBRs using the methods developed at Carnegie Mellon University (CMU). The tool will be a faster, automated version of the machine now used for this purpose at CMU and will consist of computer controlled vibrometers, software, and an internet connection to a data/knowledge base. The measurement machine will use CMU developed software to project how the IBR will vibrate when in the engine and will tell the operator that the IBR is acceptable or needs refurbishing. The machine would be used when the part is first manufactured and at regular inspection intervals. The resulting data will characterize how mistuning changes with usage and can be used with probabilistic methods for prognostics to help manage the fleet and reduce the likelihood of HCF failures.
