Abstract (en)

[origin: EP3023590A1] A turbine rotor assembly (1) includes: a rotor disc (2) formed with a plurality of axial grooves (3) on an outer periphery of the rotor disc (2); and a group (5n) of rotor blades arranged along a circumferential direction of the rotor disc (2) and engaged with the axial grooves (3) via blade stoppers (4). Each blade stopper (4) includes: a base section (41) fitted into the axial groove (3); and bend sections (42) disposed on opposite ends of the base section (41) so as to protrude from the axial groove (3) in an axial direction and bended in a radial direction of the rotor disc (2) to contact an axial end surface of the rotor disc (2). At least one of the bend sections (42) at the opposite ends includes an inward-and-outward bend part (42o, 42i) protruding outward and inward in the radial direction of the rotor disc (2).
