Abstract

TITLE: Ventilated turbine rotor. The invention relates to a turbine rotor, in particular of a low pressure turbine of a turbomachine, mounted centered on an axis X and comprising: a disc (20), an annular shell (60) including a radial fixing flange (61), the radial flange (61) being fixed to the disc (20) by a fixing member (70), a flange (80) including a first wall (82) which extends axially and a second wall (81) which extends radially outwards from the first wall (82), a ventilation circuit (90) configured to put into fluidic communication a radially internal cavity (15) formed of a radially internal side of the shell (60), with a radially external cavity (16) delimited by the flange (80) and the disc (20), the ventilation circuit (90) including at least one recess (91) provided on an upstream radial face (210) of the disc (20).
