Abstract: A bolted flange assembly for securing rotating components in a gas turbine. The bolted flange assembly includes two rotating wheels, each wheel having at least one arm extending towards a spacer positioned partially between the two rotating wheels, wherein each arm has a flange surface facing the spacer. Either each flange surface or a surface of the spacer is conical, i.e., non-perpendicular to a centerline of the gas turbine, such that in an unconstrained state, a heel end of each flange surface is closer to the spacer than a toe end of each flange surface; and a bolt extending through the arm of each rotating wheel and the spacer.

Abstract: A method of repairing a turbomachine rotor wheel including a first outer circumferential edge extending to a second outer circumferential edge through a circumferential surface, a dovetail interface extending across the outer circumferential surface between the first and second outer circumferential edges, and a bucket mounted to the dovetail interface includes identifying a defect on one of the first and second outer circumferential edges of the rotor wheel adjacent the bucket, securing the bucket in the dovetail interface to substantially constrain axial movement, and removing a portion of the one of the first and second outer circumferential edges to remove the defect.
