Abstract:
A physics–based model is used to investigate the relationship between operating conditions
and design parameters on the creep life of a stationary gas turbine high pressure
turbine (HPT) blade. A performance model is used to size the blade and to determine its
stresses. The effects of radial temperature distortion, turbine inlet temperature, ambient
temperature and compressor degradation on creep life are then examined. The results
show variations in creep life and failure location along the span of the blade enabling
better informed design and maintenance decisions.
