Abstract : An evaluation of the application of damping treatments to turbomachinery rotating and static components based on measured response characteristics of compressor and turbine stages was performed. In the evaluation, data from a shrouded fan stage, an integral turbine stage, and two stator vane assemblies were used. From the data the contributions due to material damping, interface damping and aerodynamic damping comprising the total system damping were obtained. Based on these identifications a basis for the application of damping treatments which would be effective in controlling resonant response amplitudes is established. (Author)
