Abstract
A dovetail joint between a rotor wheel and a bucket includes a male dovetail component on the rotor wheel and a female dovetail component in the bucket, wherein the male dovetail component includes four laterally projecting hooks, each hook from an uppermost hook to a lowermost hook decreasing in radial thickness and increasing in axial length. Each hook has a substantially flat top surface to effectively increase the average thickness, and a neck between the respective hooks having enlarged fillets. The new dovetail joint reduces peak stresses so as to avoid or minimize stress corrosion cracking.
