Gas Turbine Rotor/Case Structural Response to Rotating Stall: Experimental Documentation and Analytical Approach,
Abstract
This work presents experimental data describing the forcing functions and structural responses characterizing gas turbine rotor/case system vibration due to rotating stall in an axial-flow compressor. Two data sets with fundamentally different response characteristics are presented; one is supersynchronous and the other subsynchronous. Conventional beam-element rotor dynamics analysis is shown to be severely limited in its ability to predict these responses. A new analytical approach, which significantly increases structural response predictive capability for these phenomena, is briefly discussed.
