Abstract

In a gas turbine rotor of disc-type construction with a tie rod braced at least at one location along the length thereof against compressor or turbine discs by ring-shaped intermediate members, the intermediate members includes substantially conically expansible turning rings having a wider diameter end engageable in a circular groove formed in a lateral surface of one of the discs, the turning rings having at the smaller diameter end thereof an inner peripheral surface with which they are braced on the tie rod.
