Rotor assembly for gas turbine with a sealing wire

摘要

The present invention relates to a rotor assembly (1) for a rotary machine such as a gas turbine. The present solution provides a sealing wire (8) located inside a groove (6) engraved in the rotor body (3). The sealing wire (8) is responsive to radial centrifugal forces acting during normal operation of the machine, and moves radially in the groove (6) until a sealing configuration is achieved such to prevent damaging hot leakage towards machine components. Gas turbine comprising such a rotor assembly (1).
