Zusammenfassung:	A gas turbine conical flange bolted joint. 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.
