FIELD: engines and pumps.
SUBSTANCE: invention relates to gas turbines, namely, to turbo-machine high rpm loaded rotors. The gas turbine engine disk-to-shaft joint incorporates the disk external member fitted on the shaft shank splines. The turbine disk external member is furnished with axial diametrically opposite slots with their cross-section sizes exceeding those of lengthwise cross-section of the nut locking axially the turbine disk by 0.1 to 1.0 mm.
EFFECT: higher reliability of turbine operation.
