Abstract (en)
[origin: EP3926141A1] A gas turbine stator vane includes, an airfoil (13), having a leading edge (13a) and a trailing edge (13b), an outer platform (14), connected to an outer end of the airfoil (13), and an inner platform (15), connected to an inner end of the airfoil (13). The inner platform (15) has a front edge (15a) and an aft edge (15b) at the leading edge (13a) and at the trailing edge (13b) of the airfoil (13), respectively and includes a stator aft sealing portion (19) at the aft edge (15b) and at least one aft sealing rib (20), integral with the inner platform (15) and delimited by adjacent aft grooves (21) that extend parallel to each other all along the aft edge (15b) in the stator aft sealing portion (19), whereby in use the stator aft sealing portion (19) contacts a respective adjacent rotor portion of a gas turbine rotor (3) in response to thermal expansion only at the at least one aft sealing rib (20).
