Abstract (en)

Gas turbine comprises a compressor part (7) and a turbine part (13) that are rotationally fixed together. A tie rod (4) and compressor disks (29) are provided in the compressor part, and turbine disks (41) in the turbine part. The compressor disks are fixed centrally on the tie rod. The turbine disks are decentrally fixed. The gas turbine also comprises a multi-fixing disk (35) between a rear compressor disk and a front turbine disk. The multifixing disk is fixed centrally to the compressor disks. <??>Preferred Features: The multi-fixing disk is fixed decentrally to the turbine disks. An intermediate part (38) is arranged between the multi-fixing disk and a turbine disk to adjust the distance between the disks. A decentral bore (53) in the turbine disks allows the introduction of steam to the turbine blades for cooling.
