Abstract:
A method and apparatus for controlling distortion in the casing of a gas turbine are disclosed. The method uses a split in the flange ID underneath “false” flanges to tune the hoop stiffness of the casing to match the stiffness and behavior of the bolted joint. By matching the hoop carrying capability and load path of the split-line flange, as well as the thermal mass effect, the distortion can be channeled to a higher order distortion mode that can evenly distribute the deflection and approach a pure circular form.
