Unsteady Aerodynamics & Aeormechanics of Multi-Stage Turbomachinery Blading

摘要

The overall research objective was to develop the technology needed to predict accurately significant blade row forced response in a multistage environment, thereby providing accurate predictions of HCF in turbine engine blade rows. Specific objectives included: development of a benchmark standard multistage transonic research compressor; providing a quantitative understanding and predictive capability for multi-stage blade row forced response; investigating techniques to control the flow induced vibrations; considering the issue of robustness including the role of variability and fluid structure interactions.
