Abstract

The present invention relates to a stator (9) for a turbine (7), the stator (9) comprising at least two circumferentially neighbouring vanes (1), wherein the vanes (1) each comprise an airfoil (2) and an inner diameter platform (3) at the inner end of the airfoil (2) as well as an inner diameter platform cavity (13) with the inner diameter platform cavity (13) being in particular delimited by at least one side wall (15) of the inner diameter platform (3). An improved sealing of the stator (9) and thus an enhanced efficiency of the respective turbine (7) is achieved, when a gap between facing side walls (15) of circumferentially neighbouring vanes (1) is used to form an intermediate cavity (22). The invention further relates to a turbine (7) comprising such a stator (9) as well as to such a vane (1) of such a stator (9).
