Beschreibung
Zusammenfassung:	The invention relates to a turbine rotor, of a low-pressure turbine of a turbine engine for example, including a first disk, an annular seal ring including a radial flange on which is formed a scalloping defined by a plurality of scallops offering a locally increased surface, circularly distributed, said radial flange being attached to the rotor between the first disk and the second disk and a flow circuit including at least one lunule, suitable to place into fluid communication a radially inner cavity and a radially outer cavity, the lunule being formed on the radial flange of the seal ring said lunule being provided on at least one scallop.
