Abstract (en)
[origin: EP2011966A2] The device has a monoblock drum including turbine discs (11, 12), where a rim (12J) of the disc (12) includes slots in which feet (6P) of blades (6) of a turbine of a gas turbine engine are slid in axial manner. The blades are axially retained by axial retaining segments (18). A hole (12P) is formed in a rear shell (14) below the rim that is in communication at inner side of a monoblock drum with the slots of the disc (12). A passage is formed in the segments. The segments include a base housed in a groove formed in the drum.
