摘要： A bucket to wheel dovetail attachment includes axially spaced radially extending wheel fingers having discrete sections (22, 24, 26) of decreased axial thickness in a radial outward direction with transition fillets (28, 30) between sections of different thicknesses. The wheel fingers define wheel finger slots (20) for receiving correspondingly shaped bucket dovetail fingers (44). Pins (49) interconnect the buckets (12) and rotor wheel (10). The slot bottoms likewise have fillets (34). The fillets on the wheel fingers and slot bottoms have a blend of different radii with the larger radii outward of the smaller radii to reduce stress concentrations and to avoid stress corrosion cracking in steam turbine applications.

摘要： A method has been developed for predicting a remaining operational life of a turbine component (10) including: obtaining crack flaw data (30) regarding current crack flaws in the turbine component; using the crack flaw data with data (28) regarding the structure and operating conditions of the turbine component to determine (27) force loads applied to the turbine component and generate crack propagation data; applying a probalistic analysis (34) to the crack flaw data and the generated crack propagation data to generate a statistical distribution of crack data (36), and applying the statistical distribution of crack data to predict a time to failure (46) of the component by iteratively determining the force loads for successive periods of time.
